1. A client is prescribed methylprednisolone for an allergic reaction. The nurse should monitor for which potential side effect of this medication?
- A. Nausea and vomiting
- B. Weight gain
- C. Insomnia
- D. Increased appetite
Correct answer: B
Rationale: When a client is prescribed methylprednisolone, a corticosteroid, the nurse should monitor for weight gain as a potential side effect. Corticosteroids like methylprednisolone can cause weight gain and fluid retention due to their impact on metabolism and sodium retention. Nausea and vomiting are less common side effects of methylprednisolone. Insomnia and increased appetite are not typically associated with methylprednisolone use.
2. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?
- A. Apical heart rate of 60 beats/min
- B. Sweating across the forehead
- C. Poor sucking effort
- D. Respiratory rate of 30 breaths/min
Correct answer: A
Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.
3. A client with hypertension is prescribed atenolol. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Dry mouth
- D. Hypotension
Correct answer: A
Rationale: When a client is prescribed atenolol, a beta-blocker, the nurse should monitor for bradycardia, which is a potential side effect. Atenolol works by slowing the heart rate, so monitoring the client's heart rate is essential to detect and manage bradycardia promptly.
4. A client with a diagnosis of bipolar disorder is prescribed topiramate. The nurse should monitor for which potential adverse effect?
- A. Cognitive impairment
- B. Weight gain
- C. Liver toxicity
- D. Weight loss
Correct answer: A
Rationale: Correct. Topiramate is associated with cognitive impairment as an adverse effect. It is important for the nurse to monitor the client's cognitive function while on this medication to assess for any signs of cognitive decline or impairment. Choice B, weight gain, is incorrect as topiramate is actually associated with weight loss rather than weight gain. Choice C, liver toxicity, is also incorrect as topiramate is not known to cause liver toxicity. Choice D, weight loss, is not the correct answer as topiramate is not associated with weight gain.
5. A client with rheumatoid arthritis is prescribed leflunomide. What instruction should the nurse include in the client's teaching plan?
- A. Avoid alcohol while taking this medication.
- B. Take this medication with food to decrease gastrointestinal upset.
- C. Avoid sunlight while taking this medication.
- D. Report any signs of infection to the healthcare provider.
Correct answer: A
Rationale: Leflunomide can increase sensitivity to sunlight. While it is important to avoid excessive sun exposure, the critical instruction for the client is to avoid alcohol while taking this medication. Alcohol can potentiate the hepatotoxic effects of leflunomide, making it crucial for the client to abstain from alcohol consumption to prevent liver damage.
