All questions

Question 1

A prescription for hydralazine is received by the pharmacy. To prevent a potential dispensing error with its common look-alike/sound-alike counterpart, hydroxyzine, which of the following is the most critical workflow step?

  1. Verify the medication's indication with the patient's profile. (correct answer)
  2. Store the medication in a refrigerated environment.
  3. Use a separate, designated tray for counting the tablets.
  4. Apply an auxiliary label that says "Take with food."
Explanation: Hydralazine (an antihypertensive) and hydroxyzine (an antihistamine) are a well-known look-alike/sound-alike (LASA) pair. A critical safety check in the workflow is to verify the drug's indication (use) against the patient's diagnosis or profile. This helps confirm the correct medication was prescribed and selected. The other options are incorrect; neither drug requires refrigeration, a special counting tray (unless it's an allergen like sulfa), or a "Take with food" label as a primary safety measure against LASA errors.

Question 2

A technician has just filled a prescription for sulfamethoxazole/trimethoprim. To prevent cross-contamination, what is the most important action to take before using the counting tray for another patient's medication?

  1. Wipe the tray and spatula with a dry cloth.
  2. Visually inspect the tray for any tablet residue.
  3. Rinse the tray and spatula with warm water.
  4. Clean the tray and spatula with 70% isopropyl alcohol. (correct answer)
Explanation: Sulfa drugs are a common cause of severe allergic reactions. To prevent cross-contamination that could harm a subsequent patient with a sulfa allergy, the counting tray and spatula must be thoroughly cleaned with 70% isopropyl alcohol to remove all drug residue. A dry wipe, visual inspection, or water rinse is insufficient to guarantee the removal of all particles.

Question 3

A pharmacy stocks hydrochlorothiazide 25 mg and hydralazine 25 mg in bottles that look very similar. What is the most effective strategy to prevent a technician from pulling the wrong medication from the shelf?

  1. Store the medications in different, non-adjacent locations. (correct answer)
  2. Order both medications from the same manufacturer.
  3. Place a sticker on the shelf reminding staff to be careful.
  4. Store one bottle on a higher shelf than the other.
Explanation: The most effective error-prevention strategy for look-alike/sound-alike (LASA) medications is to physically separate them in inventory. Storing them in non-adjacent locations (e.g., on different shelves or with several other medications in between) significantly reduces the risk of confirmation bias and grabbing the wrong bottle by mistake. While reminders can be helpful, physical separation is a more robust engineering control.

Question 4

When entering a new prescription for a patient named Robert Johnson, the technician finds three existing profiles for "Robert Johnson" in the pharmacy system. What is the most appropriate action to prevent a medication error?

  1. Ask the patient for their date of birth to select the correct profile. (correct answer)
  2. Create a new profile to avoid confusion with the others.
  3. Select the profile with the most recent prescription fill.
  4. Ask the patient to spell their full name again.
Explanation: Using a second identifier is essential to distinguish between patients with the same name. The date of birth is the most common and reliable second identifier. This ensures the new prescription is added to the correct patient's record, preventing serious errors related to allergies, duplicate therapies, and drug interactions. Creating a new profile would lead to a fragmented and unsafe patient record.

Question 5

The final step in the workflow before a medication is bagged for sale is the pharmacist's verification. How should the technician best prepare the materials for this check?

  1. Place only the labeled vial in the verification area.
  2. Place the labeled vial and the original stock bottle in the verification area.
  3. Place the labeled vial, original stock bottle, and the original prescription in the verification area. (correct answer)
  4. Place the stock bottle back on the shelf and bring the labeled vial to the pharmacist.
Explanation: For an accurate final check, the pharmacist must be able to compare all relevant items. This includes the final product (labeled vial), the source product (original stock bottle to check NDC, lot, and expiration), and the original order (prescription). Presenting all three items together allows the pharmacist to systematically verify the "five rights" of medication administration and is a critical safety step in the workflow.

Question 6

A patient returns a sealed, unopened prescription bag to the pharmacy, stating they no longer need the medication. According to standard safety and legal practice, what should be done with this medication?

  1. It can be returned to the pharmacy's active stock if the package is untampered.
  2. It must be segregated from active inventory and processed for disposal or reverse distribution. (correct answer)
  3. It can be given to a different patient who has a prescription for the same medication.
  4. It should be immediately disposed of in the pharmacy's regular trash container.
Explanation: Once a medication has left the control of the pharmacy, its integrity and proper storage conditions cannot be guaranteed. For patient safety, it cannot be returned to stock and dispensed to another patient, even if it appears sealed and unopened. The correct procedure is to isolate it from regular inventory and handle it according to the pharmacy's policy for returned or expired medications, which usually involves a reverse distributor.

Question 7

While filling a prescription, a technician catches an error where the wrong strength was pulled from the shelf. The error was corrected before the medication was dispensed to the patient. This event should be documented as a:

  1. sentinel event.
  2. dispensing error.
  3. near miss. (correct answer)
  4. adverse drug event.
Explanation: A near miss, also known as a close call, is a medication error that is caught before it reaches the patient. Reporting near misses is a crucial part of a pharmacy's quality assurance program because it helps identify weaknesses in the workflow that can be corrected to prevent future errors from actually reaching patients.

Question 8

When a patient comes to the counter to pick up a completed prescription, which two pieces of information are most commonly used to verify their identity and ensure the right medication is given to the right person?

  1. First name and phone number
  2. Last name and prescribing doctor
  3. Full name and date of birth (correct answer)
  4. Home address and last four digits of social security number
Explanation: The industry standard for patient safety is to use at least two patient identifiers to verify identity before dispensing medications. The most common and effective combination is the patient's full name and their date of birth. This helps prevent errors, especially when multiple patients have the same or similar names.

Question 9

A technician is preparing an oral suspension of amoxicillin that requires reconstitution. Which two auxiliary labels are most important to place on the bottle to ensure patient safety and medication efficacy?

  1. "May Cause Drowsiness" and "For External Use Only"
  2. "Shake Well Before Using" and "Refrigerate" (correct answer)
  3. "Take With Food" and "Avoid Direct Sunlight"
  4. "For the Eye" and "Do Not Chew"
Explanation: Oral suspensions are not uniform solutions and require shaking to ensure the medication is evenly distributed for accurate dosing. Most reconstituted amoxicillin products require refrigeration to maintain chemical stability for the duration of therapy. These two instructions are critical for the safe and effective use of the medication. The other options are incorrect for this drug and dosage form.

Question 10

A technician is in the middle of counting warfarin 5 mg tablets when the phone rings. What is the safest course of action for the technician to take?

  1. Leave the tablets on the counting tray and answer the phone.
  2. Finish counting the warfarin, secure the medication, and then answer the phone. (correct answer)
  3. Answer the phone while simultaneously finishing the count to save time.
  4. Ask another technician to answer the phone while continuing to count.
Explanation: Warfarin is a high-alert medication where dosing errors can have severe consequences. Interruptions are a major cause of medication errors. The safest practice is to complete the critical task of counting the medication without distraction, secure it, and then attend to the secondary task (answering the phone). Multitasking or leaving medications unattended increases the risk of error.

Question 11

Which of the following environmental factors in a pharmacy is most likely to contribute to a medication error during the filling process?

  1. Bright, overhead lighting
  2. Frequent interruptions and distractions (correct answer)
  3. A comfortable room temperature
  4. Organized and clearly labeled shelves
Explanation: While all environmental factors play a role, frequent interruptions and distractions are one of the most significant causes of medication errors. When a technician's focus is broken while counting, selecting a drug, or entering data, the risk of making a mistake increases dramatically. Pharmacies often implement strategies like "no interruption zones" to mitigate this risk.

Question 12

During data entry, a technician types the directions for an eye drop as "instill 1 drop in the right eye daily". Which abbreviation correctly corresponds to "right eye"?

  1. O.D. (correct answer)
  2. O.S.
  3. O.U.
  4. A.D.
Explanation: The Latin abbreviation for right eye is O.D. (oculus dexter). O.S. (oculus sinister) is the left eye, and O.U. (oculus uterque) is both eyes. A.D. (auris dextra) means right ear. While these abbreviations are considered error-prone and writing them out is preferred, technicians must know their meanings to correctly process prescriptions.

Question 13

While entering a new prescription for amoxicillin, the technician reviews the patient's profile and sees a documented allergy to penicillin. What is the most appropriate next step in the workflow?

  1. Contact the prescriber's office to request a different antibiotic.
  2. Dispense the medication and have the pharmacist counsel the patient.
  3. Stop the filling process and immediately alert the pharmacist to the potential interaction. (correct answer)
  4. Make a note in the computer system about the allergy and continue filling the prescription.
Explanation: A penicillin allergy is a contraindication for amoxicillin due to cross-sensitivity. This is a critical clinical issue that requires a pharmacist's intervention. The technician's role is to identify this DUR (Drug Utilization Review) alert and halt the workflow to bring it to the pharmacist's immediate attention for resolution. Technicians should not make clinical decisions or contact prescribers about therapeutic alternatives independently.

Question 14

A pharmacy's policy requires an independent double-check when filling prescriptions for certain medications. This procedure is most critical for which of the following drug classes?

  1. Antibiotics
  2. High-alert medications (correct answer)
  3. Over-the-counter (OTC) medications
  4. Generic medications
Explanation: High-alert medications are drugs that bear a heightened risk of causing significant patient harm when used in error. Examples include insulin, anticoagulants (like warfarin), and certain narcotics. Safe workflow for these medications often includes a mandatory independent double-check by another technician or a pharmacist to verify the drug, strength, and dose are correct before dispensing.

Question 15

A handwritten prescription is received with the direction "ss tab po qhs". The abbreviation "qhs" is on the list of error-prone abbreviations. What is the proper interpretation?

  1. One-half tablet by mouth every hour.
  2. One-half tablet by mouth at bedtime. (correct answer)
  3. One to two tablets by mouth quickly.
  4. One-half tablet by mouth with a snack.
Explanation: "qhs" (quaque hora somni) means "at bedtime." It is considered error-prone because it can be mistaken for "qh" (every hour). Best practice is to write out the instruction, but a technician must know its correct meaning. "ss" means one-half, and "po" means by mouth. Therefore, the correct interpretation is "one-half tablet by mouth at bedtime."

Question 16

A pharmacy computer system flags a prescription for celecoxib because the patient's profile shows a severe allergy to sulfa. This alert is an example of a workflow tool designed to prevent:

  1. a drug-disease interaction.
  2. an incorrect dosage form error.
  3. a therapeutic duplication.
  4. a drug-allergy interaction. (correct answer)
Explanation: Celecoxib (Celebrex) contains a sulfonamide chemical group and is contraindicated in patients with a sulfa allergy. The computer system's alert is a Drug Utilization Review (DUR) function that warns the pharmacy staff of a potential drug-allergy interaction, which could cause a serious adverse reaction. This safety feature allows for pharmacist intervention before the drug is dispensed.

Question 17

A prescription is written for "levothyroxine 0.125 mg". How should this dose be entered into the pharmacy computer system to adhere to best practices for preventing medication errors?

  1. .125 mg
  2. 0.125 mg (correct answer)
  3. 0.1250 mg
  4. 125.0 mcg
Explanation: According to the Institute for Safe Medication Practices (ISMP), a leading zero should always be used before a decimal point for doses less than one (e.g., 0.125) to prevent the decimal from being missed. Conversely, trailing zeros (e.g., 0.1250) should never be used as they can be misread and lead to a tenfold overdose if the decimal is not seen. Therefore, "0.125 mg" is the safest representation.

Question 18

During the prescription filling process, what is the primary safety-related purpose of scanning the barcode on the manufacturer's stock bottle?

  1. To check the medication's expiration date automatically.
  2. To verify that the selected medication's NDC matches what was entered for the prescription. (correct answer)
  3. To automatically deduct the quantity from the pharmacy's perpetual inventory.
  4. To identify if the medication is a hazardous drug that requires special handling.
Explanation: The primary safety function of barcode scanning during the filling workflow is to verify that the National Drug Code (NDC) on the selected stock bottle matches the NDC associated with the prescription being filled. This confirms that the correct drug, strength, and dosage form have been selected, preventing wrong-drug errors. While scanning may trigger inventory updates, its main purpose in this context is safety verification.

Question 19

To ensure accuracy before a prescription is passed to the pharmacist for final verification, a technician's self-check should involve comparing which three items?

  1. Original prescription, printed label, and manufacturer's stock bottle. (correct answer)
  2. Patient's ID card, printed label, and filled vial.
  3. Original prescription, patient's insurance card, and stock bottle.
  4. Printed label, filled vial, and pharmacy's daily log.
Explanation: A fundamental safety check in the dispensing workflow is for the technician to compare the original prescription (or computer image), the label that was printed, and the manufacturer's stock bottle that was pulled. This "triple check" helps catch errors in drug selection, strength, and directions before the product is sent for the pharmacist's final check.
