Question 5

A prescription for 'MS Contin' is processed. This medication is considered high-alert due to its active ingredient, morphine sulfate. What is the primary safety measure a technician should observe when handling this type of medication?

  1. Wear gloves due to risk of absorption.
  2. Verify the dose and frequency are appropriate for an opioid.
  3. Check for potential drug interactions with antibiotics.
  4. Ensure it is not stored near look-alike packaging for magnesium sulfate. (correct answer)
Explanation: Morphine sulfate (MS) and magnesium sulfate (MgSO4) are a classic look-alike pair due to their abbreviations. A mix-up could be fatal, as magnesium sulfate is used for seizures or electrolyte replacement and has a vastly different dose. Verifying the dose (B) is always important, but the specific LASA risk with magnesium sulfate is a critical safety concern to address through storage strategies.

Question 6

According to the Institute for Safe Medication Practices (ISMP), which of the following medications is classified as a high-alert medication due to its narrow therapeutic index and high risk of causing significant patient harm if used in error?

  1. Amoxicillin
  2. Warfarin (correct answer)
  3. Loratadine
  4. Ibuprofen
Explanation: Warfarin is an anticoagulant classified as a high-alert medication because errors in dosing can lead to severe bleeding or clotting events. Amoxicillin (antibiotic), loratadine (antihistamine), and ibuprofen (NSAID) have a wider margin of safety and are not on the ISMP list of high-alert medications for community pharmacy.

Question 7

Which of the following medications is a high-alert chemotherapeutic agent that, when used for non-cancer indications like rheumatoid arthritis, has been prone to fatal errors when dosed daily instead of weekly?

  1. Metoprolol
  2. Metformin
  3. Methotrexate (correct answer)
  4. Methylprednisolone
Explanation: Methotrexate is a high-alert medication. For inflammatory diseases, it is typically dosed weekly. Inadvertently prescribing or dispensing it for daily use can lead to severe, life-threatening bone marrow suppression and toxicity.

Question 8

A hospital pharmacy receives an order for vinblastine. This drug should be carefully differentiated from which other high-alert chemotherapeutic agent to prevent a potentially fatal neurotoxic overdose?

  1. Vincristine (correct answer)
  2. Vinorelbine
  3. Carboplatin
  4. Cisplatin
Explanation: Vinblastine and vincristine are a well-known LASA pair of chemotherapy drugs. However, their dosing and toxicity profiles differ significantly. Vincristine has a maximum dose cap due to severe neurotoxicity, and administering a typical vinblastine dose by mistake could be fatal. This is a critical distinction in oncology pharmacy.

Question 9

The ISMP has identified errors involving different dosage strengths of which medication as a cause for concern, often recommending pharmacies stock only one or two common strengths to reduce confusion?

  1. Levothyroxine (correct answer)
  2. Metformin
  3. Azithromycin
  4. Lisinopril
Explanation: Levothyroxine is available in over a dozen closely-spaced strengths (e.g., 100 mcg, 112 mcg, 125 mcg) with color-coded but similar packaging, making it highly susceptible to selection errors. Due to its narrow therapeutic index, these errors can be clinically significant. For this reason, strategies to reduce the risk of mix-ups are crucial.

Question 10

Concentrated injectable potassium chloride is considered a high-alert medication and is often removed from patient care floor stock. What is the primary risk associated with an error involving this medication?

  1. Life-threatening cardiac arrest (correct answer)
  2. Severe hypoglycemia
  3. Anaphylactic shock
  4. Uncontrolled bleeding
Explanation: Administering concentrated potassium chloride intravenously without proper dilution can cause hyperkalemia, leading to fatal cardiac arrhythmias and cardiac arrest. This significant risk is why its storage and administration are tightly controlled.

Question 11

A patient's profile indicates an allergy to codeine. A new prescription is presented for Tylenol with Codeine #3. The pharmacist is counseling another patient.

While the technician correctly identifies the allergy issue, which of the following high-alert medications also poses a significant risk of severe respiratory depression similar to codeine?

  1. Heparin
  2. Insulin
  3. Methadone (correct answer)
  4. Potassium Chloride
Explanation: Methadone, like codeine, is an opioid and high-alert medication that poses significant risk of life-threatening respiratory depression. While heparin (bleeding), insulin (hypoglycemia), and concentrated potassium chloride (cardiac arrest) are also high-alert medications, they do not share the respiratory depression risk profile of opioids.

Question 12

A pharmacy technician is stocking a medication delivery. Which of the following pairs should be stored in separate locations, possibly with a 'Look-Alike/Sound-Alike' warning sticker, to prevent a mix-up?

  1. Metformin and Glucophage
  2. Lisinopril and Zestril
  3. Celecoxib and Citalopram (correct answer)
  4. Amoxicillin and Penicillin
Explanation: Celecoxib (Celebrex, an NSAID) and Citalopram (Celexa, an SSRI antidepressant) are a common LASA pair. Storing them separately is a key safety strategy. The other pairs are either brand/generic for the same drug (A and B) or drugs from the same class that are not considered a primary LASA pair (D).

Question 13

A hospital pharmacy technician is preparing an IV admixture. Which of the following medication classes is considered high-alert due to the risk of causing complete paralysis, including respiratory arrest, if administered to a patient not on mechanical ventilation?

  1. Antibiotics
  2. Neuromuscular blockers (correct answer)
  3. H2-receptor antagonists
  4. Proton pump inhibitors
Explanation: Neuromuscular blockers (e.g., vecuronium, rocuronium) are high-alert medications that cause muscle paralysis. If given to a patient who is not intubated and mechanically ventilated, they will cause respiratory arrest and death. For this reason, they should be segregated from other medications.

Question 14

A pharmacy receives a new prescription for hydralazine. Which of the following medications on the pharmacy shelf presents the most significant risk for a dispensing error due to its look-alike/sound-alike (LASA) name?

  1. Hydroxyzine (correct answer)
  2. Hydrochlorothiazide
  3. Hydromorphone
  4. Hydrocortisone
Explanation: Hydralazine (an antihypertensive) and hydroxyzine (an antihistamine/anxiolytic) are a well-known LASA pair. An error could lead to untreated hypertension or unintended sedation. The other options, while all starting with 'hydro-', are less phonetically and orthographically similar to hydralazine.

Question 15

A mix-up between Novolin and Novolog could have serious consequences for a diabetic patient because:

  1. one is a brand name and the other is a generic.
  2. they have different onsets and durations of action. (correct answer)
  3. one requires refrigeration and the other does not.
  4. they are manufactured by different companies.
Explanation: Novolin (human insulin) and Novolog (insulin aspart) have different pharmacokinetic profiles. For example, Novolog is a rapid-acting insulin taken with meals, while Novolin R is short-acting and Novolin N is intermediate-acting. Using the wrong one can lead to severe hyperglycemia or hypoglycemia due to the mismatch between insulin action and food intake.

Question 16
