1. A client with schizophrenia is prescribed risperidone. Which statement by the client indicates the need for further teaching?
- A. I can stop taking this medication once I feel better.
- B. This medication may cause drowsiness.
- C. This medication might make me feel drowsy.
- D. I should avoid alcohol while taking this medication.
Correct answer: A
Rationale: Clients should not stop taking risperidone abruptly once they feel better without consulting their healthcare provider.
2. A client with hypertension is prescribed lisinopril. The nurse should monitor for which potential side effect?
- A. Dry cough
- B. Hyperkalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril. Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.
3. A client with hypertension is prescribed atenolol. The nurse should monitor the client for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Hypotension
- D. Hyperglycemia
Correct answer: A
Rationale: When a client is prescribed atenolol, a beta-blocker medication used to treat hypertension, the nurse should monitor for bradycardia as a potential side effect. Atenolol works by slowing the heart rate, and one common adverse effect is bradycardia, which is a slower than normal heart rate. Monitoring the client's heart rate is essential to detect and manage this potential side effect promptly. Choices B, C, and D are incorrect because atenolol typically does not cause tachycardia, hypotension, or hyperglycemia as primary side effects. Instead, bradycardia is a common concern due to the drug's mechanism of action in reducing heart rate.
4. A client with chronic heart failure is prescribed furosemide. The nurse should monitor the client for which potential adverse effect?
- A. Increased blood glucose levels
- B. Electrolyte imbalance
- C. Dehydration
- D. Weight gain
Correct answer: C
Rationale: When a client with chronic heart failure is prescribed furosemide, a diuretic, the nurse should be vigilant for potential adverse effects. Furosemide can lead to excessive fluid loss, resulting in dehydration. Dehydration is a significant concern as it can exacerbate heart failure symptoms. Additionally, furosemide can cause electrolyte imbalances, particularly affecting potassium and sodium levels. Monitoring for signs of dehydration and electrolyte disturbances is crucial to prevent complications and ensure the client's safety and well-being. Increased blood glucose levels and weight gain are not commonly associated with furosemide use in heart failure patients, making choices A and D incorrect.
5. A client with a history of stroke is prescribed warfarin. The nurse should monitor for which potential side effect?
- A. Bleeding
- B. Weight gain
- C. Headache
- D. Dizziness
Correct answer: A
Rationale: The correct answer is A: Bleeding. Warfarin is an anticoagulant medication that works by thinning the blood. One of the potential side effects of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as unusual bruising, blood in the urine or stool, or prolonged bleeding from cuts or gums. Prompt recognition and management of bleeding are essential to prevent complications. Choices B, C, and D are incorrect as weight gain, headache, and dizziness are not common side effects of warfarin. Monitoring for bleeding is a priority due to the anticoagulant properties of warfarin.
