Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to begin CPR. Even though the living will requests no resuscitation, without a written do-not-resuscitate (DNR) order from the provider, the nurse is ethically and legally bound to initiate CPR to provide life-saving measures until further confirmation is obtained. Notifying the family (Choice A) may cause a delay in providing immediate care. Waiting for further instructions (Choice C) can be time-consuming and compromise patient outcomes. Documenting the event (Choice D) is important but should follow after initiating CPR to ensure patient safety and adherence to protocols.

Correct Answer: B

Rationale: The correct first action the nurse should take when preparing to administer a blood transfusion is to verify the blood type and crossmatch. This step is crucial to ensure compatibility and prevent transfusion reactions. Obtaining the client's consent is important but should follow the verification process. Taking baseline vital signs is necessary before starting the transfusion, but confirming compatibility takes precedence. Priming the IV with normal saline is a step done before starting the transfusion, after ensuring blood compatibility.

Correct Answer: A

Rationale: The correct answer is A: Potassium supplements. Lisinopril, an ACE inhibitor, can increase potassium levels in the body. Therefore, the nurse should instruct the client to avoid potassium supplements to prevent hyperkalemia, a potentially dangerous condition. Choices B, C, and D are incorrect because they do not have significant interactions with lisinopril that would lead to adverse effects like hyperkalemia.

Correct Answer: A

Rationale: Benzodiazepines can increase intraocular pressure, which is why they must be used cautiously in patients with glaucoma. In clients with this condition, benzodiazepines can potentially worsen symptoms and lead to further complications involving the eyes. Therefore, administering benzodiazepines to a client with glaucoma should be done with caution. Choices B, C, and D are not directly contraindicated with benzodiazepines, making them less likely to cause harm compared to administering to a client with glaucoma.

Correct Answer: A

Rationale: Corrected Rationale: Atorvastatin, an HMG CoA reductase inhibitor, can lead to hepatotoxicity. Therefore, monitoring liver function through regular tests is essential. Baseline liver function should be assessed, followed by tests at 12 weeks after starting therapy and periodically thereafter. This monitoring helps detect early signs of liver damage, including jaundice, nausea, and dark urine. Incorrect Choices Rationale: B) Renal function test is not directly affected by atorvastatin. C) Hearing screenings and D) Visual acuity screenings are not indicated for monitoring while on atorvastatin therapy.
