NUR 615 Pharmacology Exam Questions
Along with Their Answers and Rationales
Top Rated A+ 2026
Sample Questions
1. Which class of medications is commonly prescribed to manage hypertension?
o A) Antidepressants
o B) Beta-Blockers
o C) Antipsychotics
o D) Antibiotics
Answer: B) Beta-Blockers
Rationale: Beta-blockers are frequently used to lower blood pressure by reducing heart
rate and myocardial contractility.
2. A patient on warfarin therapy is advised to maintain a consistent intake of which
dietary component?
o A) Carbohydrates
o B) Protein
o C) Vitamin K
o D) Sodium
Answer: C) Vitamin K
Rationale: Vitamin K can affect the effectiveness of warfarin; thus, patients are advised
to keep their intake of vitamin K consistent to avoid fluctuations in INR levels.
3. What is the primary action of ACE inhibitors in the treatment of heart failure?
o A) Decrease heart rate
o B) Increase blood volume
o C) Reduce preload and afterload
o D) Increase contractility
Answer: C) Reduce preload and afterload
Rationale: ACE inhibitors help to decrease the workload on the heart by reducing both
preload and afterload, which is beneficial in heart failure management.
4. Which side effect is most commonly associated with morphine administration?
o A) Insomnia
o B) Nausea and vomiting
o C) Hypertension
, o D) Bradycardia
Answer: B) Nausea and vomiting
Rationale: Morphine can stimulate the chemoreceptor trigger zone in the brain, leading
to nausea and vomiting.
5. A nurse is teaching a patient about the use of metformin for diabetes management.
Which statement by the patient indicates a correct understanding?
o A) "I will take this medication only when my blood sugar is high."
o B) "I must avoid alcohol while taking metformin."
o C) "This medication can cause weight gain."
o D) "I should take this medication on an empty stomach for better absorption."
Answer: B) "I must avoid alcohol while taking metformin."
Rationale: Alcohol can increase the risk of lactic acidosis in patients taking metformin,
so it is important for patients to avoid it.
6. Which medication should a nurse administer to a patient experiencing acute asthma
exacerbation?
o A) Prednisone
o B) Albuterol
o C) Montelukast
o D) Theophylline
Answer: B) Albuterol
Rationale: Albuterol is a short-acting beta-agonist that provides rapid relief of
bronchospasm during asthma exacerbations.
7. What is a primary concern when administering potassium-sparing diuretics?
o A) Hyperkalemia
o B) Hypokalemia
o C) Dehydration
o D) Hyponatremia
Answer: A) Hyperkalemia
Rationale: Potassium-sparing diuretics can lead to elevated potassium levels, so
monitoring serum potassium is essential.
8. A patient with chronic obstructive pulmonary disease (COPD) is prescribed a long-
acting bronchodilator. Which medication might this include?
o A) Levalbuterol
o B) Salmeterol
o C) Albuterol
o D) Ipratropium
, Answer: B) Salmeterol
Rationale: Salmeterol is a long-acting beta-agonist (LABA) indicated for the
maintenance treatment of COPD and provides bronchodilation over an extended period.
9. Which class of drugs is indicated for the management of hyperlipidemia?
o A) Antihypertensives
o B) Statins
o C) Antibiotics
o D) Antivirals
Answer: B) Statins
Rationale: Statins are primarily used to lower cholesterol levels and reduce the risk of
cardiovascular events.
10. When administering digoxin, what is the most important parameter for the nurse to
monitor?
o A) Blood pressure
o B) Heart rate
o C) Respiratory rate
o D) Serum sodium levels
Answer: B) Heart rate
Rationale: Digoxin can cause bradycardia; therefore, monitoring heart rate is critical
before administration.
6. Which lab value should be monitored closely in a patient taking lithium?
o A) Blood urea nitrogen (BUN)
o B) Serum sodium
o C) Thyroid function tests
o D) Serum creatinine
Answer: B) Serum sodium
Rationale: Lithium levels can fluctuate with sodium levels; low sodium can lead to
lithium toxicity, making monitoring crucial.
7. A patient taking digoxin should be monitored for which common side effect?
o A) Hypoglycemia
o B) Visual disturbances
o C) Increased urination
o D) Hypotension
Answer: B) Visual disturbances
Rationale: Digoxin toxicity can cause visual changes such as yellow-green halos around
lights, so monitoring for these symptoms is important.
