the correct answer is right and why each distractor is wrong.
SECTION 1: PHARMACOLOGY
Q1 – Q40 | Drug Classifications, Mechanisms of Action, Indications, Contraindications, Side Effects, and Drug
Interactions
Q1: A 62-year-old male with a history of myocardial infarction is prescribed lisinopril 10 mg daily.
Three days after starting therapy, he presents to the pharmacy reporting a persistent dry cough. The
patient asks the technician if this could be related to his new medication. Which response by the
technician is most accurate?
A. Discontinue the lisinopril immediately and contact the prescriber to switch to losartan.
B. The dry cough is a common, benign side effect of ACE inhibitors caused by bradykinin
accumulation and should be reported to the prescriber for evaluation. [CORRECT]
C. Increase fluid intake because the cough is a sign of dehydration from the diuretic effect.
D. Take an over-the-counter cough suppressant containing dextromethorphan to mask the symptom.
Correct Answer: B
Rationale: ACE inhibitors like lisinopril inhibit the breakdown of bradykinin, leading to its accumulation in the lungs
and triggering a persistent dry cough in up to 20% of patients. This is a class effect; switching to an ARB (such as
losartan) is the appropriate clinical action, but the technician must route this through the prescriber—not recommend
self-discontinuation. Dextromethorphan would mask the symptom without addressing the cause, and the cough is
unrelated to dehydration.
Q2: A prescriber writes a new prescription for metformin 500 mg twice daily for a patient newly
diagnosed with type 2 diabetes. Which of the following patient statements, if overheard by the
technician, should be escalated to the pharmacist immediately?
A. “I take this medication with breakfast and dinner to reduce stomach upset.”
B. “I am scheduled for a contrast-enhanced CT scan of my abdomen tomorrow morning.”
[CORRECT]
C. “My doctor told me to monitor my blood sugar twice a week.”
D. “I have switched from regular soda to diet soda this week.”
Correct Answer: B

Rationale: Metformin carries a boxed warning for lactic acidosis, and iodinated contrast media can acutely impair
renal function, precipitating metformin accumulation and life-threatening lactic acidosis. Standard guidance is to hold
metformin at the time of contrast administration and restart only after renal function is confirmed normal 48 hours
post-procedure. The other statements reflect appropriate self-management behaviors and do not require urgent
escalation.
Q3: A patient brings in a new prescription for warfarin 5 mg daily. During data entry, the technician
notes the patient’s profile also lists levofloxacin 500 mg daily for a urinary tract infection started
yesterday. Which action is most appropriate?
A. Fill both prescriptions as written; no interaction exists between warfarin and levofloxacin.
B. Notify the pharmacist before dispensing, because fluoroquinolones can significantly increase INR
and bleeding risk when combined with warfarin. [CORRECT]
C. Substitute the levofloxacin with amoxicillin without contacting the prescriber.
D. Counsel the patient to take both medications at the same time of day to improve adherence.
Correct Answer: B
Rationale: Fluoroquinolones (including levofloxacin, ciprofloxacin) inhibit CYP450 metabolism and displace warfarin
from plasma proteins, sharply raising INR and bleeding risk. This is a clinically significant drug interaction that requires
pharmacist review and likely INR monitoring within 3–5 days. Auto-substitution is outside the technician scope, and
simultaneous administration does not mitigate the interaction.
Q4: A technician receives a prescription for hydrochlorothiazide 25 mg daily. Which of the following
laboratory values, if present on the patient’s profile, would be of greatest concern to the pharmacist
counseling on this medication?
A. Serum potassium 4.2 mEq/L
B. Serum sodium 138 mEq/L
C. Serum potassium 2.9 mEq/L [CORRECT]
D. Serum glucose 95 mg/dL
Correct Answer: C
Rationale: Thiazide diuretics like hydrochlorothiazide promote renal potassium excretion, and a baseline potassium of
2.9 mEq/L already indicates hypokalemia—adding a thiazide could worsen it to a dangerous level, causing arrhythmias.
The pharmacist would typically recommend potassium supplementation or a potassium-sparing alternative. The other
values are within normal ranges and would not contraindicate thiazide therapy.
Q5: A patient asks the technician about the difference between acetaminophen and ibuprofen for
treating a mild headache. The technician should explain that the primary distinction is:
A. Acetaminophen reduces inflammation, while ibuprofen only reduces pain and fever.
B. Ibuprofen is an NSAID that reduces pain, fever, and inflammation, while acetaminophen reduces
pain and fever but has minimal anti-inflammatory effect. [CORRECT]
C. Both medications work through the same mechanism but differ only in dosing frequency.
D. Acetaminophen is safer than ibuprofen for patients with kidney disease, but ibuprofen is safer for patients
with liver disease.
Page 2
,PTCB Exam 2026/2027 — Actual Exam Test Bank 180 Questions | 100% Correct Answers
Correct Answer: B
Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes,
providing anti-inflammatory, analgesic, and antipyretic effects. Acetaminophen works primarily in the central nervous
system to reduce pain and fever but lacks peripheral anti-inflammatory activity. NSAIDs carry renal and GI risks;
acetaminophen carries hepatic risk at high doses.
Q6: A patient newly started on sertraline 50 mg daily for depression calls the pharmacy reporting
agitation, sweating, confusion, and muscle twitching that began after a dose increase to 100 mg.
Which condition should the technician recognize as the most likely emergent concern?
A. Anticholinergic toxicity
B. Serotonin syndrome [CORRECT]
C. Neuroleptic malignant syndrome
D. Acute dystonia
Correct Answer: B
Rationale: Sertraline is a selective serotonin reuptake inhibitor (SSRI), and the triad of agitation, diaphoresis, confusion,
and neuromuscular hyperactivity (tremor, clonus, hyperreflexia) following a dose increase is classic for serotonin
syndrome. This is a medical emergency requiring immediate prescriber notification and possible emergency department
referral. The other conditions involve different drug classes and symptom profiles.
Q7: A pharmacy technician is preparing to dispense a prescription for albuterol HFA 90 mcg, 2 puffs
every 4–6 hours as needed. The patient asks whether the medication is a "rescue" inhaler or a
"controller" medication. The technician’s best response is:
A. It is a long-acting controller medication that should be used daily even when asymptomatic.
B. It is a short-acting beta-2 agonist (SABA) used as a rescue inhaler for acute bronchospasm and
should not be used on a fixed daily schedule. [CORRECT]
C. It is an inhaled corticosteroid that reduces airway inflammation over weeks of use.
D. It is an anticholinergic that works by blocking muscarinic receptors in the lungs.
Correct Answer: B
Rationale: Albuterol is a short-acting beta-2 agonist (SABA) that provides rapid bronchodilation within minutes, making
it the standard rescue inhaler for acute asthma symptoms or exercise-induced bronchospasm. Long-acting controllers
include inhaled corticosteroids (e.g., fluticasone) or LABAs (e.g., salmeterol), which should never be used for acute
rescue because of their slower onset.
Q8: A 70-year-old female is started on amlodipine 5 mg daily for hypertension. At her two-week
follow-up, she reports significant swelling in her ankles. The technician recognizes this adverse effect
is:
A. A sign of worsening heart failure that requires immediate discontinuation.
B. A common, dose-dependent side effect of dihydropyridine calcium channel blockers caused by
precapillary vasodilation. [CORRECT]
C. Caused by fluid retention from sodium reabsorption in the kidneys.
D. An allergic reaction requiring a switch to an ACE inhibitor.
Page 3
, PTCB Exam 2026/2027 — Actual Exam Test Bank 180 Questions | 100% Correct Answers
Correct Answer: B
Rationale: Amlodipine is a dihydropyridine calcium channel blocker that preferentially dilates arterioles; the resulting
pressure gradient causes fluid to leak into dependent tissues, producing peripheral edema. This is dose-dependent,
benign, and unrelated to heart failure or allergy. Reducing the dose or switching to a non-dihydropyridine (e.g.,
diltiazem) typically resolves the edema.
Q9: A pharmacy technician is checking the inventory of amlodipine, lisinopril, and
atorvastatin—three of the most dispensed medications in the United States. Which drug class does
atorvastatin belong to?
A. Angiotensin-converting enzyme (ACE) inhibitors
B. HMG-CoA reductase inhibitors (statins) [CORRECT]
C. Calcium channel blockers
D. Beta-adrenergic blockers
Correct Answer: B
Rationale: Atorvastatin inhibits HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis, reducing
LDL cholesterol and cardiovascular event risk. Lisinopril is an ACE inhibitor, amlodipine is a calcium channel blocker,
and beta-blockers include agents like metoprolol and atenolol. Knowing therapeutic classes is foundational PTCB
knowledge.
Q10: A patient is prescribed sulfamethoxazole/trimethoprim (Bactrim DS) for a urinary tract
infection. The patient’s profile also shows lisinopril 20 mg daily. Which interaction is of greatest
clinical concern?
A. Increased risk of tendon rupture
B. Hyperkalemia due to additive potassium-retaining effects [CORRECT]
C. QT prolongation from CYP3A4 inhibition
D. Reduced efficacy of the antibiotic
Correct Answer: B
Rationale: Trimethoprim acts as a potassium-sparing agent similar to amiloride; combined with an ACE inhibitor
(lisinopril), which also reduces aldosterone-mediated potassium excretion, the risk of clinically significant hyperkalemia
rises sharply—especially in elderly patients or those with renal impairment. This often warrants potassium monitoring or
temporary therapy adjustment.
Q11: A patient brings in a prescription for oxycodone 5 mg/acetaminophen 325 mg (Percocet), take 1
tablet every 6 hours as needed for pain, quantity 30, with 2 refills written. The technician should
recognize that:
A. This is a Schedule II controlled substance and cannot have refills; the prescription must be filled
within 30 days of issuance and may require a new prescription for additional quantities.
[CORRECT]
B. This is a Schedule III substance and may be refilled up to 5 times within 6 months.
C. This is a Schedule IV substance with refills permitted for one year from the date of issuance.
D. Acetaminophen combination products are Schedule V and may be refilled as written.
