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?
- A. Administer the medication as prescribed.
- B. Monitor the client for a rash or hives.
- C. Contact the healthcare provider.
- D. Give with prescribed antihistamine.
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.

A client with chronic asthma receives a prescription for montelukast, a leukotriene modifier. Which statement by the client indicates to the nurse that medication teaching was effective?
- A. I should take this medication only when I am having an asthma attack.
- B. I will not need to use my inhalers twice a day when I start this medicine.
- C. This medication will stop an asthma attack immediately.

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?
- A. Advise the caregiver that the purpose of the medication is to promote sleep, so a change in medication may be needed.
- B. Explain to the caregiver that insomnia is a common and temporary side effect when the medication is first started.
- C. Instruct the caregiver to withhold the medication until the dosage can be decreased to ensure the client's safety.
- D. Notify the healthcare provider that the dosage of the medication may need to be increased to manage the client's insomnia.
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.

- A. pH.
- B. Phosphate.

The nurse should notify the healthcare provider about which scheduled medication?
- A. Captopril.
- B. Acetaminophen.
- C. Omeprazole.
- D. Prednisone.

Rationale: Acetaminophen can cause liver toxicity, manifesting as jaundice, especially with high doses. Captopril, omeprazole, and prednisone are less commonly associated with jaundice.
Ferrous sulfate elixir is prescribed for a client with iron deficiency anemia. Which instruction should the nurse provide this client about taking the liquid medication?
- A. Use a straw to ingest.
- B. Swallow undiluted.
- C. Mix with an antacid.
- D. Take with a glass of milk.
Correct Answer: A
Rationale: Using a straw prevents tooth staining from ferrous sulfate. Undiluted swallowing risks staining, antacids reduce absorption, and milk inhibits iron absorption due to calcium.
