Question 1

1. Initiate facility procedure to replace the PCA medication cartridge using appropriate double-checks (correct answer)
2. Tell the client to press the button more frequently
3. Hold all opioid medication until the provider evaluates the client
4. Delegate to assistive personnel to obtain a pain score again in 15 minutes

Explanation: This question tests PCA safety and monitoring when medication supply is depleted. The priority concern related to PCA is maintaining continuous pain control by promptly replacing empty cartridges. Initiating facility procedure to replace the PCA medication cartridge using appropriate double-checks addresses the highest priority PCA issue by ensuring safe resumption of therapy. Telling the client to press more frequently is ineffective with an empty cartridge; holding opioids risks uncontrolled pain; delegating pain scores delays resolution. The decision-making principle for PCA monitoring is to follow medication safety protocols, including independent double-checks for high-alert drugs like opioids. Inventory checks prevent interruptions. A transferable strategy for monitoring clients on PCA is to anticipate cartridge changes based on usage rates and prepare in advance to minimize pain flares.

Question 2

1. The nurse pressing the PCA button on a schedule for the client (correct answer)
2. The client using the PCA button when pain begins to increase
3. Using repositioning and splinting along with PCA
4. Assessing pain and sedation at regular intervals while on PCA

Explanation: This question tests PCA safety and monitoring regarding proper administration roles. The priority concern related to PCA is maintaining the patient-controlled aspect to prevent overdose. The nurse pressing the PCA button on a schedule for the client should be questioned because it bypasses safety features and risks oversedation. The client using the button when pain increases is correct; using repositioning and splinting with PCA is appropriate; assessing pain and sedation regularly is essential. The decision-making principle for PCA monitoring is to adhere to patient-only activation to ensure doses align with perceived pain. Ethical guidelines prohibit proxy dosing. A transferable strategy for monitoring clients on PCA is to educate staff and clients on PCA principles to reinforce safe, autonomous use.

Question 3

1. Respiratory rate of 16/min while resting
2. Pain score of 4/10 after major surgery
3. Oxygen saturation of 97% on room air
4. Nausea and vomiting after opioid PCA use (correct answer)

Explanation: This question tests PCA safety and monitoring for common opioid side effects. The priority concern related to PCA is gastrointestinal side effects like nausea and vomiting, which can lead to dehydration or aspiration. Nausea and vomiting after opioid PCA use indicate a complication of PCA therapy because they are frequent adverse effects requiring antiemetic intervention. A pain score of 4/10 is acceptable postoperatively; oxygen saturation of 97% on room air is normal; respiratory rate of 16/min is within range. The decision-making principle for PCA monitoring involves distinguishing between expected side effects and serious complications, addressing symptoms promptly. Multimodal approaches reduce reliance on opioids. A transferable strategy for monitoring clients on PCA is to preemptively order antiemetics and monitor for GI symptoms to enhance comfort and adherence.

Question 4

1. Blood pressure of 116/68 mm Hg
2. Pain score of 3/10 after thoracic surgery
3. Heart rate of 74/min while resting
4. Oxygen saturation of 90% on 2 L/min with new excessive sleepiness (correct answer)

Explanation: This question tests PCA safety and monitoring in a COPD client with new sedation symptoms. The priority concern related to PCA is hypoxia combined with excessive sleepiness suggesting opioid-induced depression. Oxygen saturation of 90% on 2 L/min with new excessive sleepiness requires immediate intervention because it indicates worsening respiratory status needing dose reduction or support. A pain score of 3/10 is adequate; heart rate of 74/min is normal; blood pressure of 116/68 mm Hg is stable. The decision-making principle for PCA monitoring is to interpret oxygen saturation in context with sedation and respiratory effort, especially in lung disease. Trends guide interventions. A transferable strategy for monitoring clients on PCA is to use continuous capnography in COPD clients to monitor CO2 levels alongside oxygenation.

Question 5

1. Heart rate of 66/min
2. Pain score of 2/10 after major surgery
3. Blood pressure of 110/64 mm Hg
4. Falling asleep mid-sentence with respiratory rate 9/min (correct answer)

Explanation: This question tests PCA safety and monitoring for subtle signs of oversedation in high-risk clients. The priority concern related to PCA is intermittent arousal with low respiratory rate indicating progressive depression. Falling asleep mid-sentence with respiratory rate 9/min indicates a complication of PCA therapy because it reflects excessive sedation risking apnea in sleep apnea clients. A pain score of 2/10 is effective; blood pressure of 110/64 mm Hg is normal; heart rate of 66/min is within range. The decision-making principle for PCA monitoring is to intervene on early sedation signs before full unresponsiveness develops. Sedation scales quantify risk. A transferable strategy for monitoring clients on PCA is to perform frequent arousal tests, such as verbal stimulation, to assess depth of sedation.

Question 6

1. Blood pressure of 116/72 mm Hg
2. Pain score of 2/10 after surgery
3. Heart rate of 68/min while resting
4. Increasing difficulty awakening the client with oxygen saturation 91% and respiratory rate 10/min (correct answer)

Explanation: This question tests knowledge of PCA safety and monitoring in a postoperative client using intravenous opioids. The priority concern with PCA is opioid-induced respiratory depression and excessive sedation, particularly in clients with risk factors like obesity. The assessment finding of increasing difficulty awakening the client combined with an oxygen saturation of 91% and respiratory rate of 10/min requires immediate intervention because it indicates potential opioid overdose and compromised airway, necessitating actions like stopping the PCA and administering naloxone. A pain score of 2/10 is expected and indicates effective pain control, a heart rate of 68/min is within normal limits for a resting adult, and a blood pressure of 116/72 mm Hg is also normal and does not suggest instability. When monitoring PCA, nurses should prioritize assessing sedation levels and respiratory status over vital signs that are within normal ranges. Decision-making involves using tools like the Pasero Opioid-Induced Sedation Scale to evaluate arousal and intervening promptly if sedation increases. A transferable strategy for monitoring clients on PCA is to perform frequent assessments of respiratory rate, oxygen saturation, and level of consciousness, especially in the first 24 hours postoperatively, to prevent adverse events.

Question 7

1. Delegate to assistive personnel to ambulate the client in the hallway
2. Encourage the client to press the PCA button before pain becomes severe
3. Request a provider order to add a basal (continuous) PCA infusion
4. Ensure continuous oxygen saturation monitoring and frequent sedation/respiratory assessments (correct answer)

Explanation: This question tests PCA safety and monitoring in a high-risk client with obstructive sleep apnea. The priority concern related to PCA is the increased risk of respiratory depression due to somnolence and apnea. Ensuring continuous oxygen saturation monitoring and frequent sedation/respiratory assessments addresses the highest priority PCA issue by enabling early detection of hypoxia or oversedation. Encouraging button presses is standard but not priority over monitoring; requesting a basal infusion increases risk in apnea; delegating ambulation does not address monitoring needs. The decision-making principle for PCA monitoring is to heighten surveillance in clients with sleep disorders using tools like continuous oximetry. Risk stratification guides frequency of assessments. A transferable strategy for monitoring clients on PCA is to incorporate home CPAP use postoperatively and monitor for apnea episodes during sleep.

Question 8

1. Blood pressure of 118/72 mm Hg
2. Pain score of 3/10 after bowel surgery
3. Heart rate of 60/min at rest
4. Respiratory rate of 8/min with decreased level of consciousness (correct answer)

Explanation: This question tests PCA safety and monitoring for critical vital sign changes. The priority concern related to PCA is respiratory depression with altered consciousness in a cardiac client. Respiratory rate of 8/min with decreased level of consciousness requires immediate intervention because it signals potential arrest needing urgent reversal. A pain score of 3/10 is acceptable; heart rate of 60/min is normal; blood pressure of 118/72 mm Hg is stable. The decision-making principle for PCA monitoring is to prioritize respiratory assessments, intervening if rate falls below 10/min with sedation. ABC framework guides actions. A transferable strategy for monitoring clients on PCA is to set alarm parameters on monitors for low respiratory rates to prompt immediate checks.

Question 9

1. Assess the IV site and tubing for kinks or infiltration and correct the occlusion (correct answer)
2. Increase the opioid concentration in the PCA cartridge
3. Teach the client to wait 30 minutes between button presses
4. Delegate to assistive personnel to silence the alarm and notify the nurse if it returns

Explanation: This question tests PCA safety and monitoring in response to equipment alarms. The priority concern related to PCA is resolving occlusions to restore medication delivery and pain control. Assessing the IV site and tubing for kinks or infiltration and correcting the occlusion addresses the highest priority PCA issue by ensuring uninterrupted therapy. Increasing opioid concentration risks overdose; teaching to wait between presses ignores the alarm; delegating alarm silencing is unsafe without resolution. The decision-making principle for PCA monitoring is to treat alarms as indicators of potential failures requiring immediate nurse intervention. Systematic troubleshooting prevents complications like untreated pain. A transferable strategy for monitoring clients on PCA is to inspect infusion sites and tubing q4h or with alarms to maintain patency and efficacy.

Question 10

1. Increase the oxygen flow rate to 4 L/min to improve comfort during coughing
2. Assess the PCA history (attempts vs. doses delivered) and evaluate whether the client is using the PCA correctly before requesting a dose change (correct answer)
3. Stop the PCA because the client's respiratory rate is elevated
4. Delegate to the UAP to coach the client on PCA use and report back

Explanation: This question tests PCA safety and monitoring, focusing on optimizing pain control for pulmonary hygiene in post-thoracotomy clients. The priority concern is ensuring adequate pain control to enable deep breathing and coughing, which are essential for preventing postoperative pulmonary complications. The correct answer (B) addresses the highest priority by assessing PCA usage patterns and client technique before requesting dose changes, as inadequate pain control during pulmonary hygiene activities increases complication risk. Option A (increasing oxygen) doesn't address the pain issue, option C (stopping PCA) is inappropriate as the respiratory rate is normal for COPD, and option D (delegating PCA education) requires RN assessment and teaching. The decision-making principle is that post-thoracotomy clients need optimal pain control to perform pulmonary hygiene, and PCA effectiveness depends on proper client technique. The transferable strategy is to assess PCA usage patterns and provide pre-emptive dosing education for activities like coughing and incentive spirometry in thoracic surgery clients.

Question 11

1. Pinpoint pupils with increasing somnolence (correct answer)
2. Heart rate of 58/min
3. Pain score of 1/10
4. Blood pressure of 114/68 mm Hg

Explanation: This question tests PCA safety and monitoring, focusing on recognizing signs of opioid toxicity. The priority concern is identifying the constellation of symptoms that indicate dangerous levels of opioid accumulation requiring immediate intervention. The correct answer (A) identifies pinpoint pupils with increasing somnolence as the highest priority finding, as these are classic signs of opioid toxicity that, combined with the low respiratory rate, indicate impending respiratory arrest. Option B (HR 58/min) shows mild bradycardia, option C (pain 1/10) indicates good pain control, and option D (BP 114/68) represents acceptable blood pressure - while the bradycardia may be opioid-related, it is not immediately life-threatening. The decision-making principle is that neurological signs (pinpoint pupils, somnolence) combined with respiratory depression indicate opioid toxicity requiring immediate intervention including naloxone administration. The transferable strategy is to assess pupils and level of consciousness along with vital signs, as these neurological findings often precede complete respiratory arrest.

Question 12

1. The spouse pressing the PCA button for the sleeping client (correct answer)
2. The client using the PCA to treat postoperative pain
3. The client reporting pain 6/10 despite stable vital signs
4. The client having oxygen saturation of 98% on room air

Explanation: This question tests PCA safety and monitoring, specifically the critical safety principle of PCA therapy. The priority concern is preventing proxy use of PCA, which bypasses the built-in safety mechanism of client-controlled administration. The correct answer (A) identifies the spouse pressing the PCA button for a sleeping client as the behavior requiring immediate intervention, as this dangerous practice can lead to overdose and respiratory depression. Option B (using PCA for postoperative pain) is appropriate use, option C (pain despite stable vitals) may require dose adjustment but is not unsafe, and option D (normal oxygen saturation) is expected. The decision-making principle is that only the client should press the PCA button, as consciousness serves as a natural safety mechanism preventing overdose. The transferable strategy is to educate all clients and family members that PCA means "patient-controlled" and explain why proxy use creates life-threatening risks.

Question 13

1. Nausea and dizziness with position change (correct answer)
2. Pain score of 3/10
3. Oxygen saturation of 97% on room air
4. Respiratory rate of 14/min

Explanation: This question tests PCA safety and monitoring, specifically recognizing adverse effects of opioid therapy. The priority concern is identifying complications that can progress to more serious conditions if not addressed promptly. The correct answer (A) identifies orthostatic symptoms (nausea and dizziness with position change) as a complication of PCA therapy that can lead to falls and injury. Option B (pain 3/10) indicates adequate pain control, option C (SpO2 97%) shows normal oxygenation, and option D (RR 14/min) represents normal respiratory rate - these are all expected findings with appropriate PCA use. The decision-making principle is that orthostatic hypotension and associated symptoms represent a significant safety risk requiring intervention such as slower position changes, adequate hydration, and possible dose adjustment. The transferable strategy is to assess for both respiratory depression and cardiovascular side effects when monitoring clients on PCA therapy.

Question 14

1. Delegate to the assistive personnel to obtain repeat vital signs in 30 minutes
2. Request a provider order to increase the PCA dose
3. Teach the client that some pain is expected after surgery
4. Assess the IV site and verify the PCA tubing is connected and unclamped (correct answer)

Explanation: This question tests PCA safety and monitoring in a postoperative client reporting inadequate pain relief. The priority concern related to PCA is ensuring proper functioning of the delivery system to provide effective analgesia without overdose risk. Assessing the IV site and verifying the PCA tubing is connected and unclamped addresses the highest priority PCA issue because it identifies and resolves potential mechanical failures preventing medication delivery. Requesting an increase in PCA dose is inappropriate without confirming system functionality; teaching that some pain is expected does not address the reported malfunction; delegating vital signs does not resolve the immediate issue of non-delivery. The decision-making principle for PCA monitoring involves troubleshooting equipment first when clients report inefficacy, followed by reassessing pain and usage patterns. Regular checks of PCA pump history and infusion sites help ensure safe and effective pain management. A transferable strategy for monitoring clients on PCA is to educate them on proper button use and promptly investigate any reports of malfunction to maintain trust and efficacy in pain control.

Question 15

1. Assess the IV site and verify the PCA tubing is connected and unclamped (correct answer)
2. Administer an as-needed dose of intravenous opioid from a separate order
3. Reinforce use of nonpharmacologic comfort measures and reassess in 30 minutes
4. Delegate to the unlicensed assistive personnel (UAP) to obtain a repeat pain score

Explanation: This question tests PCA safety and monitoring, focusing on troubleshooting PCA delivery problems when pain control is inadequate. The priority concern is identifying mechanical or technical issues that prevent effective PCA medication delivery before considering dose adjustments or alternative medications. The correct answer (A) addresses the highest priority by systematically checking the IV site patency and PCA tubing connections, which are the most common causes of PCA delivery failure. Option B (giving separate opioid) bypasses troubleshooting and could lead to overdose if the PCA begins working, option C (nonpharmacologic measures) delays addressing severe pain, and option D (delegating pain assessment) is inappropriate as PCA troubleshooting requires RN assessment. The decision-making principle is to first verify the PCA system is functioning properly before assuming the medication dose is inadequate. The transferable strategy is to systematically assess the entire PCA delivery system from IV site to pump settings when clients report ineffective pain relief despite multiple attempts.

Question 16

1. Encourage the client to press the PCA button before physical therapy to prevent pain
2. Hold the PCA doses and stimulate the client while applying oxygen and notifying the provider/rapid response per policy (correct answer)
3. Document the findings and reassess in 1 hour
4. Delegate to the UAP to place the client on continuous pulse oximetry

Explanation: This question tests PCA safety and monitoring in high-risk populations, specifically clients with obstructive sleep apnea. The priority concern is early recognition of respiratory depression before it progresses to respiratory arrest. The correct answer (B) addresses the highest priority by immediately stopping the PCA, stimulating the client, applying oxygen, and activating the rapid response team for a client showing signs of opioid-induced respiratory depression (RR 10/min, SpO2 91%, somnolence). Option A (using PCA before therapy) ignores current respiratory compromise, option C (documenting and waiting) delays critical intervention, and option D (delegating monitoring) is inappropriate when immediate nursing intervention is required. The decision-making principle is that clients with OSA are at higher risk for opioid-induced respiratory depression and require immediate intervention at the first signs of compromise. The transferable strategy is to identify high-risk clients (obesity, OSA, elderly) and maintain heightened vigilance for respiratory depression with lower thresholds for intervention.

Question 17

1. Teach the client to press the button only when pain is severe to avoid overmedication
2. Assess whether the PCA is in lockout and verify the prescribed dose, lockout interval, and remaining volume (correct answer)
3. Request an order to increase the PCA dose immediately
4. Delegate to the UAP to check the pump settings and report back

Explanation: This question tests PCA safety and monitoring, specifically troubleshooting inadequate pain relief when the pump shows multiple attempts with few deliveries. The priority concern is determining whether the issue is mechanical, related to lockout settings, or requires dose adjustment. The correct answer (B) addresses the highest priority by systematically assessing the PCA programming (lockout interval, dose settings) and remaining medication volume to identify why deliveries are limited despite multiple attempts. Option A (teaching to wait for severe pain) promotes inadequate pain control, option C (immediately increasing dose) bypasses necessary assessment, and option D (delegating pump assessment) is inappropriate as PCA troubleshooting requires RN expertise. The decision-making principle is to understand PCA lockout mechanisms and assess programming before assuming the prescribed dose is inadequate. The transferable strategy is to review the PCA history report to differentiate between lockout-limited dosing and true inadequate analgesia when clients report poor pain control.

Question 18

1. Pain score of 3/10 with stable blood pressure
2. Increasing drowsiness requiring repeated stimulation (correct answer)
3. Heart rate of 80/min
4. Oxygen saturation of 92% on 2 L/min nasal cannula

Explanation: This question tests PCA safety and monitoring in high-risk cardiac surgery clients with multiple comorbidities. The priority concern is recognizing progressive sedation as an early warning sign of impending respiratory depression. The correct answer (B) identifies increasing drowsiness requiring repeated stimulation as a complication indicating opioid accumulation and impending respiratory compromise. Option A (pain 3/10 with stable BP) indicates adequate pain control, option C (HR 80/min) is normal, and option D (SpO2 92% on oxygen) while slightly low, is less concerning than the altered level of consciousness. The decision-making principle is that progressive sedation often precedes respiratory depression and requires immediate intervention in high-risk clients. The transferable strategy is to use standardized sedation scales and recognize that increasing drowsiness is as important as vital sign changes when monitoring PCA therapy.

Question 19

1. Stop the PCA infusion, attempt to arouse the client, support ventilation as needed, and prepare to administer naloxone per protocol (correct answer)
2. Obtain a pain reassessment and sedation score and reassess again in 30 minutes
3. Call the provider to request an antiemetic order
4. Delegate to the UAP to increase the oxygen flow rate and document the response

Explanation: This question tests PCA safety and monitoring, specifically the emergency response to opioid-induced respiratory depression. The priority concern is recognizing and responding to life-threatening respiratory depression that requires immediate reversal. The correct answer (A) addresses the highest priority with the correct sequence of interventions: stop the PCA, attempt arousal, support breathing, and prepare naloxone for this client showing severe respiratory depression (RR 8/min with difficult arousal). Option B (reassessing in 30 minutes) dangerously delays intervention, option C (requesting antiemetic) addresses a non-existent problem, and option D (delegating oxygen adjustment) is inappropriate when immediate RN intervention is required. The decision-making principle is that respiratory rate below 10/min with altered consciousness constitutes a medical emergency requiring immediate PCA cessation and naloxone administration. The transferable strategy is to memorize the emergency response sequence for opioid overdose: stop the drug, stimulate the client, support ventilation, and administer reversal agent.

Question 20

1. Pain rating of 2/10 while resting in bed
2. Respiratory rate of 8/min with difficult arousal (correct answer)
3. Blood pressure of 108/64 mm Hg
4. Heart rate of 62/min

Explanation: This question tests PCA safety and monitoring, specifically recognizing signs of opioid-induced respiratory depression. The priority concern with PCA therapy is respiratory depression, which can lead to hypoxia, respiratory arrest, and death if not immediately addressed. The correct answer (B) identifies the combination of bradypnea (RR 8/min) and altered level of consciousness (difficult arousal) as the highest priority finding requiring immediate intervention to prevent respiratory failure. Option A (pain 2/10) indicates adequate pain control, option C (BP 108/64) shows acceptable blood pressure, and option D (HR 62/min) represents normal heart rate - none of these findings indicate life-threatening complications. The decision-making principle is that respiratory depression with altered consciousness represents a medical emergency requiring immediate intervention including stopping the PCA, stimulating the client, supporting ventilation, and preparing naloxone. The transferable strategy is to monitor respiratory rate, sedation level, and oxygen saturation together as a triad for early detection of opioid-induced respiratory depression.
