Rationale: The correct answer is C. Asking clients over 18 about their organ donation status upon admission is essential to ensure their wishes are respected.

Rationale: The correct answer is C. When using brimonidine to treat open-angle glaucoma, patients may experience temporary irritation in the eyes.

Correct Answer: B

Rationale: The correct answer is B. Reporting a cough is crucial when taking lisinopril as it can be a sign of a serious side effect, such as angioedema or cough associated with ACE inhibitors. Option A is incorrect because lisinopril can be taken with or without food. Option C is incorrect as facial swelling is not an expected side effect of lisinopril. Option D is incorrect because lisinopril can cause hyperkalemia, so increasing potassium-rich foods without healthcare provider guidance can be dangerous.

Correct Answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.

Correct Answer: B
