enzyme (ACE) inhibitors?
a) Increase heart rate
b) Increase blood pressure
c) Decrease blood pressure
d) Increase renal blood flow
Answer: c) Decrease blood pressure
Rationale: ACE inhibitors block the conversion of angiotensin I to angiotensin II, a
potent vasoconstrictor, leading to vasodilation and decreased blood pressure.
2. A patient is prescribed warfarin. What is the most important aspect of patient
education regarding this medication?
a) Take the medication on an empty stomach
b) Avoid foods high in vitamin K
c) Take the medication only with food
d) Discontinue the medication during illness
Answer: b) Avoid foods high in vitamin K
Rationale: Warfarin works by inhibiting vitamin K-dependent clotting factors.
Consuming large amounts of vitamin K-rich foods (e.g., leafy green vegetables)
can interfere with the effectiveness of the medication.
3. Which class of medications is used to treat acute asthma exacerbations by
relaxing bronchial smooth muscle?
a) Leukotriene modifiers
b) Beta-2 adrenergic agonists
c) Inhaled corticosteroids
d) Mast cell stabilizers
Answer: b) Beta-2 adrenergic agonists
Rationale: Beta-2 agonists, such as albuterol, are bronchodilators that quickly
relieve acute asthma symptoms by relaxing the smooth muscles in the airways.
,4. Which side effect is most commonly associated with the use of digoxin?
a) Hypokalemia
b) Nausea and vomiting
c) Tinnitus
d) Hypotension
Answer: b) Nausea and vomiting
Rationale: Digoxin, a cardiac glycoside, can cause gastrointestinal disturbances,
including nausea and vomiting, especially if the levels become toxic.
5. A nurse is caring for a patient on a statin medication for hyperlipidemia.
Which of the following lab values should the nurse monitor closely?
a) Liver function tests
b) Complete blood count
c) Creatinine clearance
d) Serum potassium levels
Answer: a) Liver function tests
Rationale: Statins can affect liver function. Therefore, it is important to monitor
liver enzymes (e.g., AST, ALT) regularly while a patient is on statin therapy.
6. Which of the following medications is most commonly used to treat type 2
diabetes mellitus by increasing insulin sensitivity?
a) Metformin
b) Glipizide
c) Insulin glargine
d) Pioglitazone
Answer: a) Metformin
Rationale: Metformin is a biguanide that works by decreasing glucose production
in the liver and increasing insulin sensitivity in peripheral tissues, making it a first-
line treatment for type 2 diabetes.
, 7. What is the main function of calcium channel blockers in the treatment of
hypertension?
a) Increase heart rate
b) Decrease heart rate and relax blood vessels
c) Increase cardiac output
d) Increase peripheral vascular resistance
Answer: b) Decrease heart rate and relax blood vessels
Rationale: Calcium channel blockers inhibit the entry of calcium into the heart and
vascular smooth muscle, causing a reduction in heart rate, myocardial
contractility, and vasodilation, which helps lower blood pressure.
8. Which medication is commonly used as a first-line treatment for generalized
anxiety disorder (GAD)?
a) Diazepam
b) Sertraline
c) Haloperidol
d) Lithium
Answer: b) Sertraline
Rationale: Sertraline is a selective serotonin reuptake inhibitor (SSRI) commonly
used to treat anxiety and depression. SSRIs are considered first-line therapy for
generalized anxiety disorder.
9. A patient is receiving an opioid analgesic. Which of the following is the most
appropriate nursing action to prevent opioid-related constipation?
a) Increase fluid intake and encourage physical activity
b) Administer a stool softener only when constipation develops
c) Restrict fluid intake to prevent diarrhea
d) Administer a laxative after each dose of the opioid
