Question 1 of 5
A client is prescribed phenobarbital 100 mg daily for the treatment of seizures. Which statement made by the client indicates an accurate understanding of the medication phenobarbital?
Correct Answer: A
Rationale: The correct answer is A. Phenobarbital should be taken at the same time every day to maintain blood levels and enhance compliance.

One of the potential adverse effects of erythropoietin therapy is hypertension. The increased production of red blood cells can lead to elevated blood pressure levels. Therefore, monitoring for hypertension is essential to ensure the client's safety and well-being while on this medication.

Question 4 of 5
A client has been diagnosed with open-angle glaucoma. The health care provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
Correct Answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye.

Correct Answer: A
Rationale: The correct potential side effect of buspirone is drowsiness.
