Question 1:
What is the primary action of ACE inhibitors in the treatment of hypertension?
A) Dilate blood vessels
B) Increase heart rate
C) Decrease blood volume
D) Decrease the workload on the heart
Answer: A) Dilate blood vessels
Rationale: ACE inhibitors block the enzyme angiotensin-converting enzyme (ACE), which is
responsible for converting angiotensin I to angiotensin II. Angiotensin II is a potent
vasoconstrictor, so inhibiting its formation leads to vasodilation, which lowers blood pressure.
2. Medications for Respiratory Disorders
Question 2:
A nurse is teaching a patient about the use of a bronchodilator. Which of the following
instructions should the nurse include?
A) Take the medication with food to avoid gastrointestinal upset
B) Use the medication only when shortness of breath occurs
C) Use a spacer to ensure adequate inhalation of the medication
D) Take the medication only if prescribed for long-term use
Answer: C) Use a spacer to ensure adequate inhalation of the medication
Rationale: A spacer is used with inhalers to help ensure that the medication is effectively
delivered into the lungs, especially in patients with poor technique. Bronchodilators should be
used as prescribed, typically before shortness of breath occurs, but a spacer helps improve the
treatment’s efficacy.
Question 3:
Which of the following is a common side effect of corticosteroids?
A) Hypoglycemia
B) Hypotension
,C) Weight gain
D) Decreased appetite
Answer: C) Weight gain
Rationale: Corticosteroids are known to cause fluid retention and increased appetite, which can
lead to weight gain. They can also raise blood glucose levels, leading to hyperglycemia, not
hypoglycemia.
Question 4:
A client is prescribed a course of antibiotics for a bacterial infection. What is the most important
instruction to provide to the patient?
A) Stop taking the antibiotics if symptoms improve
B) Take the medication until the prescribed amount is finished
C) Take the antibiotics with milk to reduce side effects
D) Increase fluid intake while taking the medication
Answer: B) Take the medication until the prescribed amount is finished
Rationale: It is essential for patients to complete the full course of antibiotics, even if they feel
better before finishing the medication. Stopping the medication early can lead to antibiotic
resistance and incomplete eradication of the infection.
Question 5:
A patient is receiving phenytoin for seizure control. Which of the following is a common side
effect of phenytoin that the nurse should monitor?
A) Weight loss
B) Gingival hyperplasia
C) Diarrhea
D) Hypertension
Answer: B) Gingival hyperplasia
Rationale: Phenytoin is associated with a side effect of gingival hyperplasia, where the gums
become swollen and bleed easily. Regular dental checkups and good oral hygiene can help
manage this side effect.
6. Medications for Pain Management
Question 6:
Which of the following medications is an opioid analgesic?
,A) Acetaminophen
B) Ibuprofen
C) Morphine
D) Naproxen
Answer: C) Morphine
Rationale: Morphine is an opioid analgesic, commonly used to manage moderate to severe pain.
Acetaminophen, ibuprofen, and naproxen are non-opioid analgesics and have different
mechanisms of action.
Question 7:
A patient with a history of gastroesophageal reflux disease (GERD) is prescribed omeprazole.
What is the primary action of omeprazole?
A) Inhibit gastric acid production
B) Neutralize stomach acid
C) Increase mucosal protection
D) Promote gastric motility
Answer: A) Inhibit gastric acid production
Rationale: Omeprazole is a proton pump inhibitor (PPI) that works by inhibiting the proton
pump in the stomach, which reduces the production of stomach acid, helping to treat conditions
like GERD.
Question 8:
A patient with type 2 diabetes is prescribed metformin. What is the primary action of metformin
in the management of diabetes?
A) Stimulate insulin release from the pancreas
B) Decrease insulin resistance
C) Increase glucose production in the liver
D) Prevent glucose absorption in the intestines
Answer: B) Decrease insulin resistance
Rationale: Metformin works by decreasing insulin resistance in the body, allowing insulin to
work more effectively and help regulate blood glucose levels.
Question 9:
Which of the following lab tests should be monitored for a patient on warfarin therapy?
A) Hemoglobin
B) Platelet count
, C) Prothrombin time (PT)
D) Creatinine clearance
Answer: C) Prothrombin time (PT)
Rationale: Warfarin is an anticoagulant, and its effectiveness is monitored by checking the
prothrombin time (PT) and international normalized ratio (INR). These tests measure how long it
takes for blood to clot and ensure that the patient is within the therapeutic range.
Question 10:
A nurse is caring for a patient who is prescribed an SSRI (Selective Serotonin Reuptake
Inhibitor). What is a common side effect of SSRIs?
A) Sedation
B) Weight loss
C) Sexual dysfunction
D) Increased appetite
Answer: C) Sexual dysfunction
Rationale: Sexual dysfunction, including reduced libido and difficulty achieving orgasm, is a
common side effect of SSRIs. This class of antidepressants can affect serotonin levels in the
brain, which can impact sexual functioning.
Question 11:
A nurse is caring for a patient who is taking furosemide. Which of the following electrolyte
imbalances should the nurse monitor for?
A) Hyperkalemia
B) Hypernatremia
C) Hypokalemia
D) Hypocalcemia
Answer: C) Hypokalemia
Rationale: Furosemide is a loop diuretic that increases the excretion of potassium, which can
lead to hypokalemia. Monitoring potassium levels is crucial to avoid complications like
arrhythmias.
