1. A practical nurse is reviewing the medication administration record for a client prescribed prednisone. What potential side effect should the nurse monitor for?
- A. Hypoglycemia
- B. Weight loss
- C. Hypertension
- D. Diarrhea
Correct answer: C
Rationale: Prednisone, a corticosteroid, can cause side effects such as hypertension, fluid retention, and weight gain. Hypertension is a common side effect of prednisone due to its impact on sodium and fluid retention in the body. Monitoring blood pressure is crucial to detect and manage hypertension in clients taking prednisone. Choices A, B, and D are incorrect. While prednisone can indirectly affect blood glucose levels, hypoglycemia is not a common side effect. Weight gain, not weight loss, is more prevalent with prednisone use. Diarrhea is not a typical side effect associated with prednisone.
2. A client with a history of atrial fibrillation is prescribed digoxin. The nurse should monitor for which sign of digoxin toxicity?
- A. Bradycardia
- B. Tachycardia
- C. Nausea
- D. Vomiting
Correct answer: A
Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a medication used to treat atrial fibrillation, can lead to toxicity manifesting as various cardiac dysrhythmias, with bradycardia being a notable indicator. Monitoring for bradycardia is crucial as it can indicate the need for dosage adjustment or discontinuation of digoxin to prevent adverse effects. Tachycardia, nausea, and vomiting are not typically associated with digoxin toxicity, making them incorrect choices for monitoring in a client receiving this medication.
3. A client with a diagnosis of bipolar disorder is prescribed lamotrigine. The nurse should monitor for which potential adverse effect?
- A. Rash
- B. Tremors
- C. Hair loss
- D. Weight gain
Correct answer: A
Rationale: The correct answer is A: Rash. Lamotrigine can cause a rash, which may indicate a serious adverse effect like Stevens-Johnson syndrome. Monitoring for a rash is crucial in clients taking lamotrigine to promptly address any potential severe reactions.
4. A client with hypertension is prescribed hydrochlorothiazide. The nurse should monitor the client for which potential side effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: B
Rationale: When a client is prescribed hydrochlorothiazide, the nurse should monitor for hypokalemia as a potential side effect. Hydrochlorothiazide is a diuretic that can lead to potassium loss, hence monitoring potassium levels is crucial to prevent complications related to hypokalemia.
5. A client who is prescribed sildenafil for pulmonary hypertension calls the clinic for advice. Which condition should the practical nurse notify the health care provider immediately and instruct the client to stop taking the medication?
- A. The client is experiencing vision and hearing loss.
- B. The client has an erection lasting longer than 4 hours.
- C. The client is complaining of nasal congestion.
- D. The client is complaining of feeling flushed.
Correct answer: A
Rationale: The correct answer is A. If a client prescribed sildenafil for pulmonary hypertension experiences vision and/or hearing loss or an erection lasting more than 4 hours, the practical nurse should instruct the client to discontinue the medication immediately and notify the health care provider. These symptoms could indicate serious side effects that require prompt medical attention to prevent complications. Choices B, C, and D are incorrect because an erection lasting more than 2 hours (not 4 hours as stated in choice B) is a critical adverse effect that warrants immediate medical attention. Nasal congestion (choice C) and feeling flushed (choice D) are common side effects of sildenafil and typically do not necessitate immediate discontinuation of the medication or emergency intervention.
