SECTION ONE: QUESTIONS 1–100
1. A nurse is administering a medication with a high first-pass effect. Which route of
administration is the most appropriate to ensure the drug reaches systemic
circulation effectively? A. Oral B. Sublingual C. Intravenous D. Rectal C.
Intravenous Explanation: The first-pass effect refers to the metabolism of a drug
by the liver before it reaches systemic circulation. Intravenous administration
bypasses the liver initially, ensuring 100% bioavailability.
2. Which laboratory value is most critical for a nurse to monitor in a patient receiving
vancomycin? A. Serum creatinine B. Potassium level C. White blood cell count D.
Partial thromboplastin time A. Serum creatinine Explanation: Vancomycin is
nephrotoxic; therefore, monitoring renal function via serum creatinine and blood
urea nitrogen is essential to prevent kidney damage.
,3. A patient is prescribed warfarin. Which patient statement indicates an understanding
of the teaching provided? A. I will increase my intake of green leafy vegetables. B. I
will use a soft-bristled toothbrush to prevent gum bleeding. C. I will take ibuprofen if I
develop a headache. D. I will stop the medication if I see small bruises. B. I will
use a soft-bristled toothbrush to prevent gum bleeding. Explanation: Warfarin
increases bleeding risk. Using a soft toothbrush minimizes trauma to the gums, which
is a standard safety precaution for patients on anticoagulants.
4. When a nurse administers a medication that binds to a receptor and produces a
response, the drug is classified as a(n): A. Antagonist B. Partial agonist C. Agonist D.
Non-competitive inhibitor C. Agonist Explanation: An agonist is a drug that
binds to a receptor and produces a biological response similar to the body’s
endogenous substances.
5. A patient is taking levothyroxine. What time of day should the nurse instruct the
patient to take this medication? A. At bedtime with a snack B. With breakfast to
prevent nausea C. 30 to 60 minutes before breakfast D. At noon with a full glass of
water C. 30 to 60 minutes before breakfast Explanation: Levothyroxine
absorption is significantly decreased by food. Taking it on an empty stomach in the
morning ensures optimal therapeutic levels.
6. A nurse is assessing a patient for extrapyramidal symptoms (EPS) after the
administration of haloperidol. Which finding is considered an early sign of EPS? A.
Tardive dyskinesia B. Akathisia C. Hypertension D. Bradycardia B. Akathisia
Explanation: Akathisia (restlessness and the urge to move) is one of the earliest signs
of extrapyramidal side effects associated with typical antipsychotic medications.
7. Which class of antihypertensive drugs is contraindicated in pregnant patients due to
the risk of fetal renal failure? A. Beta-blockers B. Calcium channel blockers C. ACE
inhibitors D. Diuretics C. ACE inhibitors Explanation: ACE inhibitors are
classified as pregnancy Category X because they can cause severe fetal
malformations and renal failure.
8. A patient is experiencing an anaphylactic reaction to a newly administered antibiotic.
What is the nurse's priority intervention? A. Administer oral diphenhydramine B.
Stop the infusion of the antibiotic C. Contact the provider for an order D. Place the
patient in the Trendelenburg position B. Stop the infusion of the antibiotic
Explanation: The immediate priority in an anaphylactic reaction is to remove the
offending agent (the antibiotic) to stop the exposure.
9. Which drug is the antidote for benzodiazepine overdose? A. Naloxone B. Protamine
sulfate C. Flumazenil D. Acetylcysteine C. Flumazenil Explanation: Flumazenil
, is a benzodiazepine receptor antagonist used specifically to reverse the effects of
benzodiazepine toxicity.
10. A nurse is teaching a patient about the use of nitroglycerin patches. Which
instruction is accurate? A. Apply the patch to the same site every day. B. Remove the
patch at night to prevent tolerance. C. Cut the patch in half if the dose is too strong.
D. Keep the patch on while swimming or showering. B. Remove the patch at night
to prevent tolerance. Explanation: A nitrate-free interval of 10 to 12 hours is
required daily to prevent the development of drug tolerance.
11. Which insulin preparation has the shortest onset of action? A. NPH B. Regular C.
Lispro D. Glargine C. Lispro Explanation: Rapid-acting insulins like Lispro have
an onset of action within 15 minutes, which is faster than regular or intermediate-
acting insulins.
12. A nurse is caring for a patient on long-term corticosteroid therapy. The nurse should
monitor the patient for which common adverse effect? A. Hypoglycemia B. Weight
loss C. Hyperglycemia D. Hypotension C. Hyperglycemia Explanation:
Corticosteroids stimulate gluconeogenesis and increase insulin resistance, frequently
leading to elevated blood glucose levels.
13. Which class of antibiotics is associated with the risk of tendon rupture, especially in
older adults? A. Fluoroquinolones B. Aminoglycosides C. Tetracyclines D. Macrolides
A. Fluoroquinolones Explanation: Fluoroquinolones (e.g., ciprofloxacin) carry
a black box warning for the increased risk of tendinitis and tendon rupture.
14. A patient is prescribed digoxin. Which assessment finding should lead the nurse to
withhold the medication? A. Heart rate of 52 beats per minute B. Blood pressure of
110/70 mmHg C. Serum potassium of 4.2 mEq/L D. Respiratory rate of 16 breaths per
minute A. Heart rate of 52 beats per minute Explanation: Digoxin is a
negative chronotrope. It should be withheld if the apical pulse is less than 60 beats
per minute in an adult to prevent symptomatic bradycardia.
15. What is the primary purpose of adding epinephrine to a local anesthetic solution? A.
To decrease the systemic absorption of the anesthetic B. To increase the duration of
the anesthetic effect C. To prevent local allergic reactions D. To enhance the
anesthetic onset speed B. To increase the duration of the anesthetic effect
Explanation: Epinephrine causes local vasoconstriction, which keeps the anesthetic at
the site of injection for a longer period, thereby prolonging the duration of action.
16. A nurse is administering albuterol to a patient with asthma. What is the expected
therapeutic effect? A. Decreased bronchial inflammation B. Bronchodilation C.
Suppression of cough reflex D. Increased mucous production B. Bronchodilation
, Explanation: Albuterol is a short-acting beta2-agonist that relaxes bronchial
smooth muscle, resulting in bronchodilation and improved airflow.
17. Which statement by a patient demonstrates an understanding of how to take
sublingual nitroglycerin for chest pain? A. I will swallow the pill with a full glass of
water. B. I will place the tablet under my tongue and let it dissolve. C. I will crush the
tablet before placing it under my tongue. D. I will place the tablet between my cheek
and gum. B. I will place the tablet under my tongue and let it dissolve.
Explanation: Sublingual nitroglycerin is designed for rapid absorption through the
mucous membranes under the tongue and should not be swallowed or chewed.
18. A patient is receiving heparin therapy. Which test is used to monitor the effectiveness
of heparin? A. Prothrombin time (PT) B. International normalized ratio (INR) C.
Activated partial thromboplastin time (aPTT) D. Platelet count C. Activated partial
thromboplastin time (aPTT) Explanation: The aPTT is the standard laboratory test
used to monitor the therapeutic efficacy and safety of heparin infusion.
19. Which dietary instruction is most appropriate for a patient taking spironolactone? A.
Increase intake of bananas and oranges. B. Avoid salt substitutes containing
potassium. C. Take the medication with a high-protein meal. D. Decrease intake of
calcium-rich foods. B. Avoid salt substitutes containing potassium.
Explanation: Spironolactone is a potassium-sparing diuretic. Patients must avoid
extra potassium sources to prevent life-threatening hyperkalemia.
20. A patient asks why they are prescribed a "spacer" with their metered-dose inhaler
(MDI). What is the nurse's best response? A. It makes the medication taste better. B.
It increases the amount of medication delivered to the lungs. C. It prevents the need
to shake the inhaler. D. It helps you hold your breath longer. B. It increases the
amount of medication delivered to the lungs. Explanation: Spacers reduce the
amount of medication that is deposited in the mouth and throat, increasing the
volume that reaches the lower airways.
21. A nurse is preparing to administer morphine sulfate. Which of the following is the
most important assessment before administration? A. Blood pressure B. Respiratory
rate C. Oxygen saturation D. Pain level on a scale of 0-10 B. Respiratory rate
Explanation: Morphine is a potent opioid analgesic that causes dose-dependent
respiratory depression. Assessing the respiratory rate is critical for patient safety.
22. Which medication is most commonly used to treat an acute gout flare? A. Allopurinol
B. Probenecid C. Colchicine D. Acetaminophen C. Colchicine Explanation:
