Extract:
Question 1 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 2 of 5
Before administering a laxative to a bedfast client, it is most important for the nurse to perform which assessment?
Correct Answer: D
Rationale: Assessing bowel movement frequency and consistency is critical to determine the need for a laxative and monitor its effectiveness. Strength, skin integrity, and urge recognition are less directly related to laxative administration.
Question 3 of 5
A female client who is starting a new prescription for doxycycline hyclate tells the nurse that she takes birth control pills. Which action should the nurse take?
Correct Answer: B
Rationale: Doxycycline can reduce birth control pill effectiveness, requiring additional contraception. Timing separation, contraindication notification, or stopping birth control are incorrect actions.
Question 4 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 5 of 5
A client with cystitis receives a prescription for phenazopyridine. Which information should the nurse explain to the client about its therapeutic effect?
Correct Answer: A
Rationale: Phenazopyridine is a urinary analgesic that relieves pain, burning, and discomfort from irritated bladder mucosa in cystitis. It does not have antibacterial properties, calm spasms, or require specific timing related to sexual intercourse.
