Question 1

A 66-year-old man with type 2 diabetes is confused and very thirsty after 1 week of dysuria and fever. Vital signs: BP 88/52 mm Hg, HR 130/min, RR 20/min, T 38.6°C (101.5°F); glucose 920 mg/dL. Labs: serum osmolality 338 mOsm/kg (normal 275–295), pH 7.34 (normal 7.35–7.45), HCO3− 20 mEq/L (normal 22–26), serum ketones trace (normal negative). What is the nurse's PRIORITY intervention for this patient with a mixed presentation?

  1. Start isotonic IV fluids and closely monitor airway, perfusion, and urine output (correct answer)
  2. Administer sodium bicarbonate to normalize pH before giving insulin
  3. Request a provider order for computed tomography of the head for confusion
  4. Delegate to the licensed practical/vocational nurse to interpret the anion gap and adjust insulin

Explanation: This question tests recognition and treatment of diabetic emergencies, particularly a mixed DKA-HHS presentation in a type 2 diabetes patient with infection. The priority concern is stabilizing dehydration and potential airway compromise from altered mental status. Starting isotonic IV fluids and closely monitoring airway, perfusion, and urine output is the best choice as it addresses hypovolemia and supports organ function in this overlapping syndrome. Administering bicarbonate is not indicated with pH above 7.0; CT head is unnecessary without focal signs; and delegating anion gap interpretation exceeds LPN scope. This follows the ABC framework, ensuring airway and circulation first. Clinical judgment recognizes mixed presentations require fluid priority. A transferable strategy is to treat mixed diabetic emergencies with initial fluids, then insulin, while monitoring for acidosis resolution.

Question 2

A 72-year-old man with type 2 diabetes is being treated for HHS. Vital signs: BP 100/64 mm Hg, HR 110/min, RR 18/min, T 37.9°C (100.2°F); glucose 760 mg/dL. Labs: serum osmolality 330 mOsm/kg (normal 275–295), pH 7.40 (normal 7.35–7.45), HCO3− 24 mEq/L (normal 22–26), serum ketones negative (normal negative). Which assessment finding indicates HHS rather than DKA in this patient?

  1. Serum ketones negative (normal negative) (correct answer)
  2. Heart rate 110/min (normal 60–100)
  3. Blood glucose 760 mg/dL (normal fasting 70–99)
  4. Temperature 37.9°C (100.2°F)

Explanation: This question tests recognition and treatment of diabetic emergencies, distinguishing between hyperosmolar hyperglycemic state (HHS) and diabetic ketoacidosis (DKA) in a type 2 diabetes patient. The priority concern is identifying the absence of ketosis, which defines HHS and guides treatment without bicarbonate. Negative serum ketones indicate HHS rather than DKA, as HHS lacks significant ketone production despite hyperglycemia. Heart rate of 110/min reflects dehydration; blood glucose of 760 mg/dL is severe but common to both; temperature of 37.9°C suggests infection but not specificity. This uses clinical judgment to differentiate based on ketones and acidosis. Prioritization analyzes labs for syndrome identification. A transferable strategy is to check ketones in hyperglycemic crises to tailor therapy, using insulin cautiously in HHS.

Question 3

A 23-year-old man with type 1 diabetes presents with polyuria, polydipsia, and abdominal pain. Vital signs: BP 100/60 mm Hg, HR 118/min, RR 28/min (deep), T 37.7°C (99.9°F); glucose 498 mg/dL. Labs: pH 7.22 (normal 7.35–7.45), HCO3− 14 mEq/L (normal 22–26), anion gap 21 mEq/L (normal 8–12), serum ketones positive (normal negative). Which lab value requires IMMEDIATE attention?

  1. Blood glucose 498 mg/dL (normal fasting 70–99)
  2. Bicarbonate 14 mEq/L (normal 22–26) (correct answer)
  3. Serum ketones positive (normal negative)
  4. Anion gap 21 mEq/L (normal 8–12)

Explanation: This question tests recognition and treatment of diabetic emergencies, emphasizing critical lab values in diabetic ketoacidosis (DKA) for a type 1 diabetes patient. The priority concern is addressing metabolic acidosis that impairs cellular function and can lead to shock. Bicarbonate of 14 mEq/L requires immediate attention as it indicates severe acidosis, prompting urgent insulin and fluid therapy to restore acid-base balance. Blood glucose of 498 mg/dL, positive ketones, and anion gap of 21 mEq/L are consistent with DKA but secondary to the bicarbonate depletion. This applies clinical judgment by prioritizing bicarbonate as a direct measure of acidosis. The prioritization framework uses lab analysis to identify threats to homeostasis. A transferable strategy is to correlate low bicarbonate with pH in DKA for timely intervention.

Question 4

A 75-year-old woman with type 2 diabetes is brought in for lethargy and dry mucous membranes after several days of vomiting from gastroenteritis. Vital signs: BP 94/56 mm Hg, HR 122/min, RR 18/min, T 37.2°C (99.0°F); glucose 880 mg/dL. Labs: serum osmolality 346 mOsm/kg (normal 275–295), pH 7.39 (normal 7.35–7.45), HCO3− 23 mEq/L (normal 22–26), serum ketones negative (normal negative). Which assessment finding indicates HHS in this patient?

  1. Serum osmolality 346 mOsm/kg (normal 275–295) (correct answer)
  2. Bicarbonate 23 mEq/L (normal 22–26)
  3. Arterial pH 7.39 (normal 7.35–7.45)
  4. Serum ketones negative (normal negative)

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically identifying indicators of hyperosmolar hyperglycemic state (HHS) in an elderly type 2 diabetes patient. The priority concern is recognizing severe hyperosmolality causing neurological symptoms and dehydration. Serum osmolality of 346 mOsm/kg indicates HHS as it reflects extreme hypertonicity from prolonged hyperglycemia without ketosis. Bicarbonate of 23 mEq/L, arterial pH of 7.39, and negative ketones are normal and consistent with non-acidotic HHS. This applies clinical judgment by prioritizing osmolality as the defining feature. The prioritization framework analyzes labs to differentiate HHS from DKA. A transferable strategy is to use osmolality and ketone status to confirm HHS and guide rehydration.

Question 5

A 22-year-old woman with type 1 diabetes reports 24 hours of vomiting after a viral illness and now has polyuria, polydipsia, and abdominal pain. Vital signs: BP 92/58 mm Hg, HR 124/min, RR 28/min with deep respirations, T 37.8°C (100.0°F); bedside glucose 486 mg/dL. Labs: arterial pH 7.12 (normal 7.35–7.45), HCO3− 10 mEq/L (normal 22–26), anion gap 26 mEq/L (normal 8–12), serum ketones positive (normal negative). What is the nurse's PRIORITY intervention for this patient?

  1. Administer sodium bicarbonate IV push to rapidly correct the acidosis
  2. Initiate continuous IV regular insulin infusion immediately without giving fluids first
  3. Start large-bore IV access and begin isotonic fluid resuscitation with 0.9% sodium chloride (correct answer)
  4. Delegate to the unlicensed assistive personnel to obtain hourly neurologic checks

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically diabetic ketoacidosis (DKA) in a patient with type 1 diabetes presenting with metabolic acidosis and dehydration. The priority concern is addressing severe dehydration and hypotension to restore perfusion and prevent organ failure. Starting large-bore IV access and beginning isotonic fluid resuscitation with 0.9% sodium chloride is the best choice because it rapidly corrects volume depletion, which is critical before initiating insulin therapy to avoid worsening hypotension. Administering sodium bicarbonate is less optimal as it is not routinely indicated unless pH is below 6.9; starting insulin without fluids risks circulatory collapse; and delegating neuro checks, while important, does not address the immediate life-threatening hypovolemia. This aligns with the ABC prioritization framework, focusing on circulation first, followed by the nursing process of assessment and intervention. Clinical judgment involves recognizing that fluid resuscitation precedes insulin in hypotensive DKA patients to stabilize hemodynamics. A transferable strategy is to always prioritize airway, breathing, and circulation in diabetic emergencies, ensuring volume status is addressed before correcting hyperglycemia or acidosis.

Question 6

A 73-year-old woman with type 2 diabetes is admitted with HHS after 4 days of poor intake and a respiratory infection. Vital signs: BP 90/54 mm Hg, HR 128/min, RR 22/min, T 38.2°C (100.8°F); glucose 1,040 mg/dL. Labs: serum osmolality 352 mOsm/kg (normal 275–295), pH 7.40 (normal 7.35–7.45), HCO3− 25 mEq/L (normal 22–26), serum ketones negative (normal negative). What is the nurse's PRIORITY intervention for this patient?

  1. Obtain a urine specimen for ketones before initiating any therapy
  2. Start isotonic IV fluids and monitor hemodynamic response closely (correct answer)
  3. Administer IV dextrose to prevent hypoglycemia during treatment
  4. Delegate to the unlicensed assistive personnel to adjust the IV fluid rate based on blood pressure

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically hyperosmolar hyperglycemic state (HHS) in an elderly type 2 diabetes patient with infection and poor intake. The priority concern is correcting severe dehydration and hypotension to restore organ perfusion. Starting isotonic IV fluids and monitoring hemodynamic response closely is the best choice as it addresses the massive fluid deficit from osmotic diuresis in HHS. Obtaining urine ketones delays care and is unnecessary in non-ketotic HHS; administering IV dextrose risks worsening hyperglycemia; and delegating IV rate adjustments exceeds UAP scope. This uses the ABC framework, prioritizing circulation. Clinical judgment involves recognizing HHS requires 4-10 liters of fluid initially. A transferable strategy is to prioritize volume resuscitation in HHS before insulin, assessing urine output and vital signs frequently.

Question 7

A 27-year-old woman with type 1 diabetes is admitted for DKA after a skin infection. Vital signs: BP 94/58 mm Hg, HR 122/min, RR 30/min (deep), T 38.2°C (100.8°F); glucose 540 mg/dL. Labs: pH 7.09 (normal 7.35–7.45), HCO3− 8 mEq/L (normal 22–26), anion gap 30 mEq/L (normal 8–12), potassium 4.8 mEq/L (normal 3.5–5.0). What is the nurse's PRIORITY intervention to implement first?

  1. Begin continuous IV regular insulin infusion per protocol
  2. Start 0.9% sodium chloride IV bolus and reassess circulatory status (correct answer)
  3. Administer antiemetic medication as prescribed to control nausea
  4. Obtain a repeat arterial blood gas to confirm acidosis severity

Explanation: This question tests recognition and treatment of diabetic emergencies, focusing on initial steps in severe diabetic ketoacidosis (DKA) for a type 1 diabetes patient. The priority concern is correcting dehydration before addressing hyperglycemia to avoid exacerbating hypotension. Starting 0.9% sodium chloride IV bolus and reassessing circulatory status is the best choice as it restores volume, essential prior to insulin. Beginning IV insulin risks collapse; antiemetics are adjunctive; and repeat ABG is unnecessary with confirmed acidosis. This applies the ABC prioritization, ensuring circulation. Clinical judgment follows DKA protocols emphasizing fluids first. A transferable strategy is to assess vital signs and initiate fluids immediately in hypotensive DKA patients.

Question 8

A 31-year-old woman with type 1 diabetes arrives with polyuria, polydipsia, and abdominal pain after missing insulin while treating a sinus infection. Vital signs: BP 96/60 mm Hg, HR 126/min, RR 32/min (deep), T 37.9°C (100.2°F); glucose 468 mg/dL. Labs: pH 7.14 (normal 7.35–7.45), HCO3− 11 mEq/L (normal 22–26), anion gap 24 mEq/L (normal 8–12), serum ketones positive (normal negative). Which lab value requires IMMEDIATE attention?

  1. Anion gap 24 mEq/L (normal 8–12)
  2. Arterial pH 7.14 (normal 7.35–7.45) (correct answer)
  3. Serum ketones positive (normal negative)
  4. Blood glucose 468 mg/dL (normal fasting 70–99)

Explanation: This question tests recognition and treatment of diabetic emergencies, emphasizing critical lab values in diabetic ketoacidosis (DKA) for a type 1 diabetes patient. The priority concern is addressing severe metabolic acidosis that can lead to coma or death. Arterial pH of 7.14 requires immediate attention as it indicates profound acidosis from ketoacid accumulation, necessitating urgent insulin and fluid therapy. Anion gap of 24 mEq/L and positive ketones support DKA but are secondary to pH; blood glucose of 468 mg/dL is expected but less immediately life-threatening. This applies clinical judgment by prioritizing pH as a marker of acidosis severity. The prioritization framework uses the nursing process to analyze labs for imminent threats. A transferable strategy is to monitor pH and bicarbonate in suspected DKA to guide aggressive treatment.

Question 9

A 67-year-old woman with type 2 diabetes is admitted for HHS after a week of cough and fever. Vital signs: BP 88/54 mm Hg, HR 128/min, RR 20/min, T 38.7°C (101.7°F); glucose 1,100 mg/dL. Labs: serum osmolality 360 mOsm/kg (normal 275–295), pH 7.42 (normal 7.35–7.45), HCO3− 25 mEq/L (normal 22–26), serum ketones negative (normal negative). Which lab value requires IMMEDIATE attention?

  1. Arterial pH 7.42 (normal 7.35–7.45)
  2. Serum ketones negative (normal negative)
  3. Serum osmolality 360 mOsm/kg (normal 275–295) (correct answer)
  4. Bicarbonate 25 mEq/L (normal 22–26)

Explanation: This question tests recognition and treatment of diabetic emergencies, highlighting critical lab values in hyperosmolar hyperglycemic state (HHS) for a type 2 diabetes patient. The priority concern is managing extreme hyperosmolality that causes altered mental status and seizures. Serum osmolality of 360 mOsm/kg requires immediate attention as it drives HHS pathophysiology, necessitating slow correction with fluids. Arterial pH of 7.42, negative ketones, and bicarbonate of 25 mEq/L are normal, confirming non-acidotic state. This uses clinical judgment to prioritize osmolality for guiding rehydration rate. The prioritization framework analyzes labs for neurological risk. A transferable strategy is to calculate effective osmolality in HHS to prevent cerebral edema during treatment.

Question 10

A 25-year-old man with type 1 diabetes presents with DKA after missing insulin due to nausea. Vital signs: BP 98/60 mm Hg, HR 120/min, RR 32/min (deep), T 37.5°C (99.5°F); glucose 480 mg/dL. Labs: pH 7.15 (normal 7.35–7.45), HCO3− 10 mEq/L (normal 22–26), anion gap 27 mEq/L (normal 8–12), potassium 5.2 mEq/L (normal 3.5–5.0). The nurse should QUESTION which treatment order for this patient?

  1. Start 0.9% sodium chloride IV fluids as prescribed
  2. Begin continuous cardiac monitoring
  3. Hold insulin therapy until the anion gap is within normal range (correct answer)
  4. Start IV regular insulin infusion per protocol

Explanation: This question tests recognition and treatment of diabetic emergencies, evaluating orders in diabetic ketoacidosis (DKA) for a type 1 diabetes patient. The priority concern is appropriately timing insulin to resolve ketosis and acidosis. The nurse should question holding insulin therapy until the anion gap is normal because insulin is needed to close the gap by stopping ketogenesis. Starting IV fluids and insulin is standard; cardiac monitoring addresses electrolyte risks. This applies clinical judgment per DKA protocols requiring insulin to normalize the gap. Prioritization uses the nursing process to implement evidence-based care. A transferable strategy is to continue insulin until anion gap closes, even if glucose normalizes, adding dextrose as needed.

Question 11

A 68-year-old woman with type 2 diabetes is admitted with confusion and dehydration after a urinary tract infection. Vital signs: BP 98/60 mm Hg, HR 118/min, RR 18/min, T 38.0°C (100.4°F); glucose 860 mg/dL. Labs: serum osmolality 332 mOsm/kg (normal 275–295), pH 7.38 (normal 7.35–7.45), HCO3− 24 mEq/L (normal 22–26), serum ketones negative (normal negative). Which lab value requires IMMEDIATE attention?

  1. Serum osmolality 332 mOsm/kg (normal 275–295) (correct answer)
  2. Arterial pH 7.38 (normal 7.35–7.45)
  3. Bicarbonate 24 mEq/L (normal 22–26)
  4. Serum ketones negative (normal negative)

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically identifying critical lab values in hyperosmolar hyperglycemic state (HHS) for a type 2 diabetes patient with infection. The priority concern is addressing severe hyperosmolality leading to neurological changes and dehydration. Serum osmolality of 332 mOsm/kg requires immediate attention as it confirms HHS and drives osmotic diuresis, necessitating prompt fluid resuscitation. Arterial pH of 7.38, bicarbonate of 24 mEq/L, and negative ketones are normal and do not indicate acidosis or ketosis, which are absent in pure HHS. This uses clinical judgment by prioritizing labs that explain the patient's confusion and dehydration. The prioritization framework involves analyzing osmolality as the key differentiator in HHS. A transferable strategy is to check serum osmolality in non-ketotic hyperglycemia to guide rehydration therapy.

Question 12

A 70-year-old man with type 2 diabetes is admitted with HHS related to pneumonia. Vital signs: BP 92/58 mm Hg, HR 126/min, RR 20/min, T 38.5°C (101.3°F); glucose 1,010 mg/dL. Labs: serum osmolality 348 mOsm/kg (normal 275–295), pH 7.41 (normal 7.35–7.45), HCO3− 26 mEq/L (normal 22–26), serum ketones negative (normal negative). The nurse should QUESTION which treatment order for this patient?

  1. Begin 0.9% sodium chloride IV bolus as prescribed
  2. Start IV regular insulin infusion per protocol after fluid resuscitation begins
  3. Restrict oral and IV fluids to prevent fluid overload (correct answer)
  4. Monitor serum electrolytes and glucose at frequent intervals per protocol

Explanation: This question tests recognition and treatment of diabetic emergencies, focusing on appropriate orders in hyperosmolar hyperglycemic state (HHS) for an elderly type 2 diabetes patient. The priority concern is managing severe dehydration without causing fluid overload or electrolyte imbalances. The nurse should question restricting oral and IV fluids because HHS requires aggressive rehydration to correct hypovolemia from osmotic diuresis. Beginning 0.9% sodium chloride IV bolus addresses dehydration; starting IV insulin after fluids is standard; and monitoring electrolytes and glucose is essential. This uses clinical judgment to identify contraindicated orders per HHS guidelines. Prioritization follows the nursing process by questioning unsafe interventions. A transferable strategy is to advocate for adequate fluids in HHS, adjusting based on cardiac status and urine output.

Question 13

A 24-year-old man with type 1 diabetes presents with abdominal pain, nausea, and polyuria after a recent gastroenteritis. Vital signs: BP 100/62 mm Hg, HR 120/min, RR 28/min (deep), T 37.6°C (99.7°F); glucose 520 mg/dL. Labs: pH 7.10 (normal 7.35–7.45), HCO3− 9 mEq/L (normal 22–26), anion gap 28 mEq/L (normal 8–12), potassium 5.6 mEq/L (normal 3.5–5.0). The nurse should QUESTION which treatment order for this patient?

  1. Begin 0.9% sodium chloride IV bolus as prescribed
  2. Start continuous IV regular insulin infusion per protocol
  3. Administer potassium chloride 40 mEq IV now (correct answer)
  4. Place the patient on continuous cardiac monitoring

Explanation: This question tests recognition and treatment of diabetic emergencies, focusing on appropriate interventions for diabetic ketoacidosis (DKA) with initial hyperkalemia. The priority concern is safely managing electrolyte imbalances while treating acidosis and hyperglycemia. The nurse should question administering potassium chloride 40 mEq IV now because the patient's potassium is already elevated at 5.6 mEq/L, and insulin therapy will shift it intracellularly, potentially causing hypokalemia later but making immediate supplementation dangerous. Beginning 0.9% sodium chloride IV bolus addresses dehydration; starting IV insulin treats the underlying cause; and cardiac monitoring is prudent for electrolyte shifts. This applies clinical judgment by evaluating electrolyte levels before supplementation, using the nursing process to question unsafe orders. Prioritization follows DKA protocols that withhold potassium if above 5.2 mEq/L initially. A transferable strategy is to assess potassium levels serially in DKA, supplementing only when below 5.2 mEq/L after insulin starts.

Question 14

A 74-year-old man with type 2 diabetes has a mixed presentation after 4 days of diarrhea and poor intake. Vital signs: BP 90/56 mm Hg, HR 124/min, RR 24/min, T 37.8°C (100.0°F); glucose 780 mg/dL. Labs: serum osmolality 326 mOsm/kg (normal 275–295), pH 7.28 (normal 7.35–7.45), HCO3− 17 mEq/L (normal 22–26), serum ketones positive (normal negative). Which assessment finding indicates DKA is present in addition to HHS?

  1. Serum osmolality 326 mOsm/kg (normal 275–295)
  2. Heart rate 124/min (normal 60–100)
  3. Blood glucose 780 mg/dL (normal fasting 70–99)
  4. Arterial pH 7.28 (normal 7.35–7.45) (correct answer)

Explanation: This question tests recognition and treatment of diabetic emergencies, identifying mixed diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) in a type 2 diabetes patient. The priority concern is detecting acidosis amid hyperosmolality, which alters treatment. Arterial pH of 7.28 indicates DKA presence with HHS, as it shows metabolic acidosis from ketones, requiring insulin and fluids. Serum osmolality of 326 mOsm/kg suggests HHS; blood glucose of 780 mg/dL and heart rate of 124/min are nonspecific. This applies clinical judgment by correlating pH with ketones for diagnosis. Prioritization analyzes acid-base status. A transferable strategy is to treat mixed DKA-HHS with fluids first, then insulin, monitoring for acidosis resolution.

Question 15

A 21-year-old man with type 1 diabetes is treated for DKA. Current data: glucose 240 mg/dL, pH 7.32 (normal 7.35–7.45), HCO3− 18 mEq/L (normal 22–26), anion gap 14 mEq/L (normal 8–12), potassium 3.6 mEq/L (normal 3.5–5.0). Vital signs are stable. What is the nurse's PRIORITY intervention at this time?

  1. Stop the insulin infusion because the glucose is now below 250 mg/dL
  2. Add dextrose to IV fluids per protocol while continuing insulin to close the anion gap (correct answer)
  3. Transition immediately to oral diabetes medications and discontinue IV therapy
  4. Delegate to the unlicensed assistive personnel to adjust the insulin infusion rate based on anion gap

Explanation: This question tests recognition and treatment of diabetic emergencies, managing resolving diabetic ketoacidosis (DKA) when glucose decreases but acidosis persists. The priority concern is closing the anion gap without causing hypoglycemia. Adding dextrose to IV fluids per protocol while continuing insulin is the best choice as it allows ongoing ketosis resolution while preventing low glucose. Stopping insulin risks rebound ketosis; transitioning to oral meds is premature; and delegating infusion adjustments exceeds UAP scope. This uses clinical judgment per DKA protocols to continue insulin until gap normalizes. Prioritization follows glucose and gap monitoring. A transferable strategy is to switch to dextrose-containing fluids when glucose falls below 250 mg/dL in DKA, maintaining insulin infusion.

Question 16

A 78-year-old woman with type 2 diabetes is recovering from HHS and is preparing for discharge after treatment for a urinary tract infection. Current labs: glucose 180 mg/dL (normal fasting 70–99), serum osmolality 296 mOsm/kg (normal 275–295), pH 7.40 (normal 7.35–7.45), serum ketones negative (normal negative). The patient states, "If I'm sick and not eating, I should stop checking my blood sugar." What is the nurse's PRIORITY response?

  1. "Correct; checking is only needed when you are eating normally."
  2. "You should check your blood glucose more often when sick and follow your sick-day plan." (correct answer)
  3. "Ask the provider to decide whether you should monitor your glucose during illness."
  4. Delegate to the unlicensed assistive personnel to teach the patient how to adjust diabetes medications

Explanation: This question tests recognition and treatment of diabetic emergencies, focusing on patient education to prevent recurrent hyperosmolar hyperglycemic state (HHS) in type 2 diabetes. The priority concern is correcting misconceptions about self-management during illness to avoid dehydration and hyperglycemia. Responding that you should check blood glucose more often when sick and follow your sick-day plan is best as it promotes early detection and adjustment, preventing HHS. Agreeing with the incorrect statement reinforces error; deferring to provider abdicates nursing role; and delegating teaching exceeds UAP scope. This applies clinical judgment in patient-centered education. Prioritization uses the teaching-learning process. A transferable strategy is to teach sick-day rules, including frequent monitoring and when to seek help, to all diabetes patients.

Question 17

A 22-year-old woman with type 1 diabetes reports 24 hours of vomiting after a recent viral illness and now has polyuria, polydipsia, and abdominal pain. Vital signs: blood glucose 520 mg/dL, blood pressure 92/58 mm Hg, heart rate 124/min, respiratory rate 30/min with deep rapid respirations, oxygen saturation 98% on room air. Labs: arterial pH 7.12 (normal 7.35–7.45), bicarbonate 10 mEq/L (normal 22–26), anion gap 26 mEq/L (normal 8–12), serum ketones positive (normal negative). What is the nurse's PRIORITY intervention for this patient?

  1. Administer sodium bicarbonate intravenously per protocol
  2. Initiate isotonic intravenous fluids (0.9% sodium chloride) with large-bore access (correct answer)
  3. Obtain a urine specimen for culture and sensitivity before starting treatment
  4. Delegate capillary blood glucose checks to unlicensed assistive personnel every hour

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically diabetic ketoacidosis (DKA). The priority concern is addressing severe dehydration and hemodynamic instability, as evidenced by hypotension (92/58 mm Hg) and tachycardia (124/min). Initiating isotonic intravenous fluids (0.9% sodium chloride) with large-bore access is the best choice because fluid resuscitation must precede insulin therapy to prevent cardiovascular collapse and improve tissue perfusion. Sodium bicarbonate (A) is rarely indicated in DKA and only for severe acidosis (pH <7.0); obtaining a urine specimen (C) delays critical treatment; delegating glucose checks (D) is appropriate but not the immediate priority when the patient is hemodynamically unstable. The clinical judgment principle is ABC prioritization - circulation takes precedence over metabolic corrections. A transferable strategy for diabetic emergencies is to always assess and stabilize hemodynamics first before addressing hyperglycemia or acidosis.

Question 18

A 24-year-old woman with type 1 diabetes arrives with polyuria, polydipsia, and abdominal pain after a recent urinary tract infection. Vital signs: blood glucose 560 mg/dL, blood pressure 94/62 mm Hg, heart rate 120/min, respiratory rate 32/min with deep rapid respirations. Labs: arterial pH 7.10 (normal 7.35–7.45), bicarbonate 9 mEq/L (normal 22–26), anion gap 28 mEq/L (normal 8–12), serum ketones positive (normal negative). Which assessment finding indicates diabetic ketoacidosis (DKA) in this patient?

  1. Serum osmolality 290 mOsm/kg (normal 275–295)
  2. Deep, rapid respirations with a low bicarbonate level (correct answer)
  3. Blood glucose above 500 mg/dL without ketones
  4. Confusion with normal arterial pH

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically identifying diagnostic criteria for DKA. The priority concern is recognizing the pathophysiologic hallmarks that distinguish DKA from other hyperglycemic states. Deep, rapid respirations (Kussmaul breathing) with a low bicarbonate level (9 mEq/L) indicates DKA because this compensatory respiratory pattern occurs in response to severe metabolic acidosis. Normal osmolality (A) doesn't indicate DKA; hyperglycemia without ketones (C) suggests HHS; confusion with normal pH (D) could indicate HHS but not DKA. The clinical judgment principle is recognizing the triad of DKA: hyperglycemia, ketosis, and metabolic acidosis with compensatory hyperventilation. A transferable strategy for recognizing DKA is to look for Kussmaul respirations combined with laboratory evidence of acidosis (low pH, low bicarbonate) and positive ketones.

Question 19

A 79-year-old woman with type 2 diabetes is admitted for hyperosmolar hyperglycemic state (HHS) after pneumonia. Vital signs: blood glucose 860 mg/dL, blood pressure 90/56 mm Hg, heart rate 110/min, respiratory rate 18/min. Labs: serum osmolality 332 mOsm/kg (normal 275–295), arterial pH 7.38 (normal 7.35–7.45), bicarbonate 24 mEq/L (normal 22–26), serum ketones negative (normal negative). The provider prescribes several orders. The nurse should QUESTION which treatment order for this patient?

  1. Begin 0.9% sodium chloride intravenous infusion and titrate to blood pressure and urine output
  2. Start regular insulin infusion after initial fluid replacement is underway
  3. Administer furosemide intravenously now for dehydration-related oliguria (correct answer)
  4. Monitor serum electrolytes and glucose at least every 1–2 hours during treatment

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically identifying inappropriate orders in HHS management. The priority concern is preventing iatrogenic complications during treatment of severe dehydration. The nurse should question administering furosemide intravenously for oliguria because diuretics are contraindicated in HHS - these patients have profound volume depletion, and oliguria is due to dehydration, not fluid overload. Starting with isotonic fluids (A) is appropriate for initial resuscitation; insulin after fluids (B) follows correct sequencing; frequent monitoring (D) is essential during treatment. The clinical judgment principle is recognizing contraindications - diuretics worsen dehydration in hyperglycemic emergencies. A transferable strategy is understanding that oliguria in diabetic emergencies indicates severe dehydration requiring fluid replacement, never diuresis.

Question 20

A 30-year-old woman with type 1 diabetes presents with abdominal pain, nausea, and polyuria after a recent dental infection. Vital signs: BP 102/66 mm Hg, HR 114/min, RR 28/min (deep), T 38.0°C (100.4°F); glucose 460 mg/dL. Labs: pH 7.25 (normal 7.35–7.45), HCO3− 15 mEq/L (normal 22–26), anion gap 20 mEq/L (normal 8–12), serum ketones positive (normal negative). What is the nurse's PRIORITY intervention?

  1. Delegate to the unlicensed assistive personnel to obtain a 12-lead electrocardiogram
  2. Provide diabetes diet teaching and reinforce sick-day rules
  3. Obtain a repeat serum ketone level before initiating treatment
  4. Start 0.9% sodium chloride IV fluids and assess response to volume resuscitation (correct answer)

Explanation: This question tests recognition and treatment of diabetic emergencies, specifically initial management of diabetic ketoacidosis (DKA) in a type 1 diabetes patient with infection. The priority concern is addressing dehydration and shock from osmotic diuresis. Starting 0.9% sodium chloride IV fluids and assessing response to volume resuscitation is the best choice as it stabilizes hemodynamics before insulin. Providing diet teaching is for later; repeating ketones delays care; and delegating ECG exceeds UAP scope. This follows ABC prioritization, focusing on circulation. Clinical judgment recognizes fluids as foundational in DKA. A transferable strategy is to secure IV access and bolus fluids in unstable diabetic emergencies, reassessing frequently.
