1. A client with a history of atrial fibrillation is prescribed diltiazem. The nurse should monitor for which potential side effect?
- A. Hypotension
 - B. Tachycardia
 - C. Headache
 - D. Hyperglycemia
 
Correct answer: A
Rationale: The correct answer is A: Hypotension. Diltiazem is a calcium channel blocker that can cause hypotension by relaxing blood vessels and reducing blood pressure. Monitoring blood pressure is essential to detect and manage this potential side effect. Choices B, C, and D are incorrect because diltiazem typically does not cause tachycardia, headache, or hyperglycemia as common side effects.
2. A client with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium. The nurse should instruct the client to report which potential side effect?
- A. Dry mouth
 - B. Blurred vision
 - C. Nausea
 - D. Tachycardia
 
Correct answer: A
Rationale: The correct answer is A: Dry mouth. Tiotropium, a commonly prescribed medication for COPD, can cause dry mouth as a side effect. While it may not be severe, clients should report it if it becomes bothersome. Dry mouth is a common side effect of tiotropium due to its anticholinergic properties. Blurred vision, nausea, and tachycardia are not typically associated with tiotropium use in the context of COPD.
3. A client with a history of stroke is prescribed clopidogrel. The nurse should monitor for which potential side effect?
- A. Bleeding
 - B. Weight gain
 - C. Nausea
 - D. Headache
 
Correct answer: A
Rationale: When a client with a history of stroke is prescribed clopidogrel, the nurse should monitor for potential side effects, especially bleeding. Clopidogrel is an antiplatelet medication that works by preventing blood clots. One of the major risks associated with clopidogrel is an increased tendency to bleed. Therefore, monitoring for signs of bleeding, such as easy bruising, blood in stool or urine, or prolonged bleeding from minor cuts, is crucial to ensure patient safety and early intervention if needed.
4. A client with a diagnosis of schizophrenia is prescribed olanzapine. The nurse should monitor for which potential side effect?
- A. Weight gain
 - B. Insomnia
 - C. Dry mouth
 - D. Headache
 
Correct answer: A
Rationale: When a client with schizophrenia is prescribed olanzapine, the nurse should monitor for weight gain as a potential side effect. Olanzapine is known to cause metabolic changes that can lead to weight gain, making it crucial for the nurse to closely monitor the client's weight during treatment. This side effect is significant as it can impact the client's overall health and well-being, so early detection and intervention are essential to manage it effectively.
5. A client with a diagnosis of generalized anxiety disorder is prescribed alprazolam. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
 - B. Dry mouth
 - C. Nausea
 - D. Headache
 
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Alprazolam, a medication commonly used to treat anxiety disorders, can cause drowsiness as a common side effect. Clients should be advised not to drive or operate heavy machinery until they know how the medication affects them to ensure their safety.
