Practice Questions & Rationales
As a medical-surgical nursing educator, I have developed this study guide to bridge clinical
practice with pharmacy technician certification preparation. The questions below reflect the
cognitive complexity required for safe pharmacy practice, emphasizing critical thinking and
prioritization—skills essential for both the PTCE and real-world pharmacy operations.
SECTION 1: PHARMACOLOGY & THERAPEUTIC CLASSIFICATIONS
Question 1
A patient presents a new prescription for lisinopril. During a follow-up call two weeks later, the
patient reports a persistent, dry, nonproductive cough that interferes with sleep. Which action is
most appropriate for the pharmacy technician?
A. Recommend an over-the-counter cough suppressant
B. Tell the patient to continue the medication and reassess in one month
C. Document the complaint and refer the patient to the pharmacist for evaluation
D. Suggest taking the medication at bedtime to minimize cough
Correct Answer: C
Detailed Rationale:
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor, and persistent dry cough is a well-
documented class effect occurring in approximately 5–20% of patients . While the cough is not
life-threatening, it significantly impacts quality of life and may lead to nonadherence. The
pharmacy technician’s role is to recognize this as a potential adverse drug event requiring
pharmacist intervention. The pharmacist may consider switching to an angiotensin receptor
blocker (ARB) such as losartan, which is less likely to cause cough .
Why the Other Options Are Incorrect:
A: Recommending an OTC cough suppressant is inappropriate because the cough is caused by a
prescription medication, not a primary respiratory condition. Suppressing the symptom does
not address the underlying drug effect, and some OTC products may interact with
antihypertensive therapy.
B: Advising the patient to continue and reassess in one month delays appropriate intervention
and may result in the patient discontinuing the medication independently, potentially leading
to uncontrolled hypertension.
D: Changing the administration time does not mitigate ACE inhibitor-induced cough, which is a
systemic pharmacologic effect unrelated to timing. This advice falls outside the technician’s
scope and could delay appropriate management.

Question 2
During medication profile review, a technician notices that a patient on chronic warfarin therapy
has been prescribed sulfamethoxazole/trimethoprim for a urinary tract infection. What is the
technician’s priority action?
A. Process the prescription as written and counsel the patient on bleeding precautions
B. Alert the pharmacist immediately because of the significant drug interaction
C. Contact the prescriber to request an alternative antibiotic without consulting the pharmacist
D. Note the interaction in the patient’s profile and proceed with filling
Correct Answer: B
Detailed Rationale:
Sulfamethoxazole/trimethoprim can significantly potentiate warfarin’s anticoagulant effect,
substantially increasing bleeding risk . This interaction occurs through multiple mechanisms,
including inhibition of warfarin metabolism and displacement from protein binding sites. The
technician’s scope of practice includes identifying and escalating potential drug interactions to
the pharmacist, who can then evaluate the clinical significance and determine whether to
contact the prescriber for an alternative agent or adjust warfarin dosing with close INR
monitoring .
Why the Other Options Are Incorrect:
A: Processing the prescription without pharmacist review disregards a potentially life-
threatening interaction. Counseling on bleeding precautions is insufficient when a safer
alternative may be available.
C: Contacting the prescriber is a pharmacist responsibility, not a technician function. The
technician should escalate to the pharmacist, who will then communicate with the prescriber.
D: Simply documenting the interaction without escalation fails to protect the patient.
Documentation alone does not constitute appropriate intervention for a clinically significant
drug interaction.
Question 3
A patient with type 2 diabetes has been prescribed metformin. When organizing this medication
by pharmacologic class, where should the technician place it?
A. GLP-1 receptor agonist
B. Biguanide
C. Sulfonylurea
D. DPP-4 inhibitor
Correct Answer: B
Detailed Rationale:
Metformin belongs to the biguanide class of antidiabetic agents. It works primarily by decreasing
hepatic glucose production and improving insulin sensitivity. Common adverse effects include
gastrointestinal upset and, rarely, lactic acidosis in patients with renal impairment.
Understanding drug classifications is foundational to the Pharmacology for Technicians domain
of the PTCE .

Why the Other Options Are Incorrect:
A: GLP-1 receptor agonists include semaglutide, liraglutide, and dulaglutide. They mimic incretin
hormones to increase insulin secretion and slow gastric emptying.
C: Sulfonylureas include glipizide and glyburide. They stimulate insulin release from pancreatic
beta cells and carry a risk of hypoglycemia.
D: DPP-4 inhibitors include sitagliptin and linagliptin. They prevent the breakdown of incretin
hormones, enhancing insulin secretion in a glucose-dependent manner.
SECTION 2: MEDICATION SAFETY & ERROR PREVENTION
Question 4
During final inventory review, a pharmacy technician discovers a bottle of nitroglycerin 0.4 mg
sublingual tablets that has been transferred from its original manufacturer container into a
standard amber prescription vial. What is the most appropriate action?
A. Refrigerate the vial to preserve potency
B. Add a desiccant packet and return it to active inventory
C. Dispense the medication if the expiration date has not passed
D. Remove the medication from inventory and notify the pharmacist
Correct Answer: D
Detailed Rationale:
Sublingual nitroglycerin tablets are highly volatile and must be dispensed and stored in their
original, tightly closed, light-resistant glass container. The original packaging is specifically
designed to protect the medication from environmental factors that degrade potency .
Transferring the tablets to a generic amber vial compromises their stability, and the medication
should not be dispensed because its potency cannot be assured. This is a classic medication
safety question testing knowledge of special storage requirements for high-alert medications.
Why the Other Options Are Incorrect:
A: Refrigeration is not recommended for nitroglycerin and does not reverse degradation that has
already occurred from improper storage.
B: Adding a desiccant does not restore stability compromised by removal from the original
container. The original container itself provides necessary protection.
C: An unexpired date does not guarantee potency when storage requirements have been
violated. Dispensing this medication could result in therapeutic failure during an acute angina
episode.

Question 5
A prescription is presented for a pediatric patient: amoxicillin 400 mg/5 mL suspension, “Take 7.5
mL by mouth every 12 hours for 10 days.” How many milligrams of amoxicillin will the patient
receive per dose?
A. 400 mg
B. 500 mg
C. 600 mg
D. 800 mg
Correct Answer: C
Detailed Rationale:
The concentration is 400 mg per 5 mL, which equals 80 mg/mL. To calculate the dose: 80 mg/mL
× 7.5 mL = 600 mg per dose . This type of calculation appears frequently on the PTCE and requires
proficiency with ratio and proportion. The technician must be able to verify that prescribed doses
align with safe pediatric ranges and accurately calculate quantities to dispense.
Why the Other Options Are Incorrect:
A: 400 mg would be the dose if the patient received 5 mL, not 7.5 mL.
B: 500 mg does not correspond to any logical calculation from the given concentration and
volume.
D: 800 mg would require 10 mL of the suspension, exceeding the prescribed 7.5 mL volume.
Question 6
A pharmacy technician receives a prescription for warfarin 2.5 mg tablets with the following
directions: “Take 1 tablet daily except Sunday; take 2 tablets on Sunday.” How many tablets
should be dispensed for a 30-day supply?
A. 30 tablets
B. 31 tablets
C. 35 tablets
D. 42 tablets
Correct Answer: C
Detailed Rationale:
The patient takes 8 tablets per week (1 tablet × 6 days + 2 tablets × 1 day). Over 30 days
(approximately 4.3 weeks), the requirement is approximately 34.3 tablets, so 35 tablets are
needed to provide the full 30-day regimen . This question tests the technician’s ability to interpret
complex sig codes, calculate days’ supply, and determine accurate dispensing quantities—all
essential for preventing both under- and over-dispensing.
Why the Other Options Are Incorrect:
A: 30 tablets would provide only 1 tablet daily, which does not account for the Sunday double
dose.
B: 31 tablets is an arbitrary number that does not align with the weekly dosing pattern.
D: 42 tablets would dispense 6 tablets per week, exceeding the prescribed amount and creating
a risk of diversion or waste.
