Correct Answer: D

Rationale: The priority action for the nurse in this situation is to gently lower the client to the floor. This action helps prevent injury to both the client and the nurse. It is important to ensure a safe environment and protect the client from falling, as well as to maintain the nurse's own safety while providing care.

Correct Answer: C

Rationale: Pinching the skin before inserting the needle is essential in elevating the subcutaneous tissue away from the muscle. This technique ensures that the medication is administered into the correct tissue layer, promoting proper absorption and decreasing the risk of injecting into muscle tissue.

Correct Answer: B

Rationale: Theophylline should be administered on a regular around-the-clock schedule to provide the best bronchodilating effect and reduce the potential for adverse effects. The correct dosing schedule of 8 a.m., 4 p.m., and midnight ensures that the client receives consistent dosing throughout the day. Other options do not provide the necessary around-the-clock coverage. It's important to note that food may affect the absorption of the medication, which is why the dosing schedule should not be tied to meal times.

Correct Answer: A

Rationale: Administering oxygen via a non-rebreather mask is the priority intervention for a client with pulmonary edema to improve oxygenation and address respiratory distress. Adequate oxygenation is essential to support vital organ function. Administering furosemide intravenously, inserting a Foley catheter to monitor urine output, and positioning the client in a high Fowler's position are important interventions but are secondary to ensuring optimal oxygenation in this client with pulmonary edema.

Correct Answer: C

Rationale: The Good Samaritan Act shields healthcare professionals who act in good faith and offer reasonable care from malpractice claims, irrespective of the client's outcome. In this scenario, the nurse stopping to render aid at the accident scene and applying pressure to the bleeding groin wound would likely be covered by the Good Samaritan Act, protecting the nurse from legal repercussions related to the subsequent leg amputation.
