Correct Answer: C

Rationale: A low sodium diet is recommended for a client who has hypertension. Therefore, the nurse should recommend 3 oz of chicken breast as the best choice for the client's diet because it contains 30 - 90 mg of sodium. Choice A, 1 packet of reconstituted dry onion soup, and Choice B, 3 oz of lean cured ham, are high in sodium content, which is not suitable for a client with hypertension. Choice D, 1/2 cup of canned baked beans, is also high in sodium, making it a less suitable choice compared to 3 oz of chicken breast.

Correct Answer: B

Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because inspecting the pin site every 4 hours is necessary but not the priority in this case. Choice C is incorrect as it is not essential for two personnel to hold the halo device during repositioning. Choice D is incorrect because applying powder frequently can actually increase the risk of skin issues by clogging pores and causing irritation.

Correct Answer: B

Rationale: When using the ABC approach to client care, the nurse should identify that the priority intervention is administering oxygen. In this scenario, the client's oxygen saturation is only 91%, which is below the normal range of 95% and above. Oxygen is essential for adequate tissue perfusion and oxygenation of vital organs. Administering oxygen takes precedence over other interventions to ensure the client's physiological needs are met first. Choice A can be addressed after ensuring adequate oxygenation. Choice C is important for preventing postoperative complications but is not as urgent as addressing oxygen saturation. Choice D is a common postoperative intervention, but in this case, ensuring adequate oxygenation is the priority over IV fluid administration.

Correct Answer: D

Rationale: The correct answer is D. During an electromyography (EMG) procedure, small needle electrodes are inserted into the muscles to identify muscle weakness and evaluate local nerve responses. This information is crucial for the client to know beforehand. Choice A is incorrect because radioisotopes are not used in EMG procedures. Choice B is incorrect because flushing is not a common occurrence during EMG. Choice C is incorrect because claustrophobia is more relevant to MRI or CT scans, not EMG procedures.

Correct Answer: C

Rationale: The correct answer is C because the client should have a quick-acting source of 15 g of carbohydrates to treat hypoglycemic episodes, such as 4 oz of regular soda. Choice A is incorrect because while exercise can help manage blood sugar levels, it can also increase the risk of hypoglycemia if not properly managed. Choice B is incorrect as skipping insulin when not eating can lead to hyperglycemia, not prevent hypoglycemia. Choice D is incorrect because certain oral diabetic medications can indeed cause hypoglycemia, not just insulin.
