Introduction
This comprehensive examination is designed to rigorously assess the knowledge and skills essential for success on the
Pharmacy Technician Certification Board (PTCB) certification exam. The assessment covers the top 200 prescription
drugs, focusing on brand/generic names, therapeutic classifications, mechanisms of action, side effect profiles, and
critical safety information. It integrates foundational theory with applied professional knowledge, including regulatory
and legal compliance, ethical standards, and real-world clinical scenarios. The following 200 multiple-choice questions
are structured to evaluate your understanding of drug information, pharmacy calculations, inventory management,
and patient interaction. Each question is followed by a detailed rationale to reinforce learning, emphasizing the
,practical decision-making required in a contemporary pharmacy setting. Prepare to demonstrate your readiness for this
pivotal step in your professional career.
SECTION ONE: QUESTIONS 1 – 100
1. A patient presents a prescription for Levothyroxine. Which of the following is the correct brand name for this
medication?
A. Synthroid
B. Levoxyl
C. Euthyrox
D. All of the above
🟢 Correct answer: D
🔴 Explanation: Levothyroxine is a synthetic thyroid hormone available under multiple brand names, including
Synthroid, Levoxyl, and Euthyrox. All are bioequivalent and interchangeable with a physician's approval. Therefore, all
options are correct.
2. A technician is preparing a 250 mL IV bag of Normal Saline to which 1 gram of Cefazolin is added. The final
concentration of the solution is:
A. 1 mg/mL
B. 2 mg/mL
C. 4 mg/mL
D. 0.4 mg/mL
🟢 Correct answer: C
🔴 Explanation: 1 gram is equal to 1000 mg. Dividing the total milligrams by the total volume (1000 mg / 250 mL)
yields a concentration of 4 mg/mL. This is a fundamental pharmacy calculation.
,3. Albuterol is primarily classified as which type of adrenergic agonist?
A. Alpha-1 agonist
B. Beta-1 agonist
C. Beta-2 agonist
D. Alpha-2 agonist
🟢 Correct answer: C
🔴 Explanation: Albuterol is a short-acting beta-2 adrenergic agonist. It is selective for the beta-2 receptors found in
the bronchial smooth muscle, causing bronchodilation with minimal cardiac effects compared to beta-1 agonists.
4. A patient with a sulfa allergy should avoid which of the following medications?
A. Amoxicillin
B. Hydrochlorothiazide
C. Omeprazole
D. Levothyroxine
🟢 Correct answer: B
🔴 Explanation: Hydrochlorothiazide (HCTZ) is a thiazide diuretic. Thiazides contain a sulfonamide group and are
known to cross-react in patients with a true sulfa allergy. Amoxicillin, Omeprazole, and Levothyroxine do not contain
this chemical moiety.
5. What is the recommended storage temperature range for most refrigerated medications in a pharmacy?
A. 20°C to 25°C
B. 15°C to 30°C
C. 2°C to 8°C
D. -20°C to -10°C
🟢 Correct answer: C
🔴 Explanation: The standard refrigerator temperature range for storing medications (excluding vaccines which may
, have different requirements) is 2°C to 8°C (36°F to 46°F). This range ensures the stability of most biological and
temperature-sensitive products.
6. A pharmacist is reviewing a prescription for a controlled substance and finds it is missing the DEA number.
What is the appropriate action for the technician to take?
A. Look up the DEA number in the patient's profile.
B. Fill the prescription and note the missing number later.
C. Process the prescription using the prescriber's NPI number.
D. Flag the prescription for the pharmacist to call the prescriber to obtain it.
🟢 Correct answer: D
🔴 Explanation: A DEA number is a legal requirement for a controlled substance prescription to be valid. The
technician cannot guess or use a substitute number. The pharmacist must contact the prescriber's office to obtain
the valid DEA number before dispensing.
7. Which of the following is the antidote for a suspected overdose of Acetaminophen?
A. Naloxone
B. Flumazenil
C. Acetylcysteine
D. Atropine
🟢 Correct answer: C
🔴 Explanation: Acetylcysteine (Mucomyst) is the specific antidote for acetaminophen toxicity. It works by
replenishing glutathione stores in the liver, preventing the toxic metabolite from causing hepatic necrosis. Naloxone
is for opioid overdose, and Flumazenil is for benzodiazepines.
8. A patient is prescribed Warfarin. In addition to the medication, the pharmacy should provide counseling
regarding:
A. Avoiding potassium-rich foods.
B. Monitoring for signs of lactic acidosis.
