Correct Answer: A

Rationale: The correct statement for the nurse to make is to advise the client to check the oxygen equipment daily for proper function. This is crucial to ensure the client's home oxygen therapy is working effectively and safely. Choice B is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous. Choice C is incorrect as oxygen tanks should be stored upright, not lying flat. Choice D is incorrect and unsafe advice, as smoking near an oxygen source can lead to a fire hazard.

Correct Answer: D

Rationale: In a client with a history of myocardial infarction, a respiratory rate of 16/min should be reported to the provider. Changes in respiratory rate can indicate cardiac or pulmonary issues that need further evaluation. The other vital signs provided (blood pressure, heart rate, and LDL cholesterol level) are within normal limits and do not directly relate to potential complications following a myocardial infarction.

Correct Answer: B

Rationale: The correct answer is to assist the client to a sitting position. Placing the client in a sitting position helps facilitate easier access during the thoracentesis procedure by allowing gravity to assist in the removal of pleural fluid. Placing the client in a prone, supine, or lateral position would not provide the optimal positioning needed for a thoracentesis and could make the procedure more challenging or uncomfortable for the client.

Correct Answer: C

Rationale: The correct answer is C: Bananas. Bananas are rich in potassium and should be included in the diet of clients taking furosemide, a potassium-wasting diuretic. Grapes, apples, and rice are not as high in potassium as bananas and would not be as effective in replenishing potassium levels in clients taking furosemide.

Correct Answer: D

Rationale: A WBC count of 15,000/mm3 is elevated, which may indicate infection, a common concern postoperatively. An elevated WBC count suggests the body is fighting an infection, and prompt reporting to the provider is essential for further evaluation and treatment. Serosanguineous drainage on the surgical dressing is expected in the immediate postoperative period, respiratory rate of 16/min is within the normal range, and a heart rate of 90/min is also within an acceptable range postoperatively. Therefore, these findings do not raise immediate concerns that necessitate reporting to the provider.
