and Rationales |Pass Guaranteed
Introduction
The Patient Safety and Quality Assurance domain constitutes approximately 12.5%
of the Pharmacy Technician Certification Exam (PTCE). This comprehensive
question bank is designed to test your knowledge across all key subtopics,
including:
• High-alert medications and LASA (Look-Alike/Sound-Alike) drugs
• Medication error prevention strategies
• Error-prone abbreviations and leading/trailing zeros
• Issues requiring pharmacist intervention
• Event reporting systems (MedWatch, VAERS, DEA forms)
• Root-Cause Analysis (RCA) and Quality Improvement
• Types of prescription errors
• Hygiene, cleaning, and PPE standards
• Barcode scanning and technology safeguards
• Continuous Quality Improvement (CQI) programs
Section 1: High-Alert Medications & LASA Drugs
,1. A pharmacy technician receives a prescription for hydralazine but notices
the stock bottle of hydroxyzine is nearby. This situation is a prime example of
which type of risk?
A. Therapeutic duplication
B. Adverse drug reaction
C. Look-alike/sound-alike (LASA) error
D. Drug-drug interaction
Correct Answer: C
Rationale: Hydralazine and hydroxyzine have similar spellings and can be easily
confused during order entry or filling. This is a classic LASA risk that requires
strategies like separation of inventory or Tall Man lettering to prevent.
2. Which of the following is considered a high-alert medication according to
the Institute for Safe Medication Practices (ISMP)?
A. Acetaminophen
B. Insulin
C. Loratadine
D. Multivitamin
Correct Answer: B
Rationale: Insulin is classified as a high-alert medication because dosing errors can
lead to severe hypoglycemia or hyperglycemia, causing significant patient harm.
3. What is the primary purpose of using Tall Man lettering on medication
labels?
A. To make labels easier to read for elderly patients
B. To distinguish look-alike/sound-alike drug names
C. To comply with insurance billing requirements
D. To indicate the drug’s-controlled substance schedule
Correct Answer: B
Rationale: Tall Man lettering uses uppercase letters to highlight differences in
,similar drug names (e.g., hydroxyzine vs. hydralazine), reducing the risk of
selection errors.
4. Which of the following pairs represents a LASA medication risk?
A. Amoxicillin and penicillin
B. Ceftriaxone and cefazolin
C. Glipizide and glyburide
D. Lisinopril and amlodipine
Correct Answer: C
Rationale: Glipizide and glyburide are both antidiabetic medications with similar
names and are a well-known LASA pair that can be confused during dispensing.
5. A technician is storing medications in the pharmacy. Which strategy best
prevents LASA errors?
A. Storing all medications alphabetically regardless of class
B. Separating look-alike/sound-alike medications on different shelves
C. Placing all high-alert medications together
D. Storing medications by expiration date only
Correct Answer: B
Rationale: Physically separating LASA medications reduces the likelihood of
selecting the wrong product during dispensing.
6. Which of the following is a high-alert medication that requires special
double-check procedures?
A. Vitamin C
B. Heparin
C. Diphenhydramine
D. Calcium carbonate
Correct Answer: B
Rationale: Heparin is a high-alert anticoagulant. Dosing errors can cause serious
bleeding or clotting events, so independent double-checks are recommended.
, 7. What does the abbreviation "LASA" stand for in medication safety?
A. Long-Acting Safety Assessment
B. Look-Alike/Sound-Alike
C. Low-Alert Safety Analysis
D. Licensed Alternative Safety Agent
Correct Answer: B
Rationale: LASA stands for Look-Alike/Sound-Alike, referring to medications that
can be easily confused due to similar names or packaging.
8. Which of the following medications is classified as high-alert due to its
narrow therapeutic index?
A. Warfarin
B. Acetaminophen
C. Ibuprofen
D. Cetirizine
Correct Answer: A
Rationale: Warfarin has a narrow therapeutic index, and small dosing errors can
lead to severe bleeding or thrombosis. It is classified as a high-alert medication.
9. A pharmacy technician notices that two insulin products have similar
packaging. What should the technician do?
A. Ignore the similarity and continue dispensing
B. Alert the pharmacist and suggest separating the products
C. Combine the products on the same shelf for convenience
D. Remove one product from inventory
Correct Answer: B
Rationale: Alerting the pharmacist and separating similar products is the
appropriate action to prevent LASA errors. The technician should not make
inventory decisions independently.
