Question 1 of 5
A client with a history of anaphylactic reaction to penicillin receives a prescription for cephalexin 500 mg PO twice daily. Which action should the nurse take?
Correct Answer: B
Rationale: Cephalexin may cause cross-reactivity in penicillin-allergic clients, so monitoring for allergic reactions like rash or hives is critical. Administering without monitoring, contacting the provider immediately, or giving antihistamines prophylactically are less appropriate.
Question 2 of 5
An older client with heart failure (HF), coronary artery disease (CAD), and hypertension (HTN), is receiving these daily prescriptions: atenolol, furosemide, and enalapril. Which assessments should the nurse include in evaluating the effectiveness of the medications? (Select all that apply.)
Correct Answer: B,C,D
Rationale: B: Daily weight monitors fluid retention (furosemide effectiveness). C: Heart sounds assess heart failure control (atenolol, enalapril). D: Blood pressure evaluates hypertension management (atenolol, enalapril). Bowel sounds and range of motion are unrelated to these medications’ effects.
Question 3 of 5
A client with narcolepsy receives a new prescription for methylphenidate. Prior to administration of the medication, the nurse should review the medical record for which condition?
Correct Answer: D
Rationale: Methylphenidate, a stimulant, can exacerbate hypertension, requiring careful review of blood pressure history. Hypercholesterolemia, bronchitis, and diabetes are less critical concerns.
Question 4 of 5
During a home visit, the nurse assesses a client with Alzheimer's disease who recently started a new prescription for rivastigmine. The caregiver reports that the client seems to be thinking more clearly but is not sleeping well at night. Which action should the nurse take?
Correct Answer: B
Rationale: Insomnia is a common, often temporary side effect of rivastigmine. Explaining this reassures the caregiver. Rivastigmine is for cognition, not sleep, and withholding or increasing the dose is inappropriate without provider guidance.
Question 5 of 5
The nurse prepares to administer a scheduled dose of labetalol PO to a client with hypertension. The client's vital signs are a temperature of 99° F (37.2° C), a heart rate of 48 beats/minute, respirations of 16 breaths/minute, and a blood pressure of 150/90 mm Hg. Which action should the nurse take?
Correct Answer: D
Rationale: A heart rate of 48 beats/minute indicates bradycardia, a concern with labetalol (a beta-blocker). Withholding the dose and notifying the provider is appropriate to prevent worsening bradycardia.
