Correct Answer: B

Rationale: The correct answer is B: Driving a car. Driving a car can be physically and emotionally taxing, increasing the risk of complications soon after a myocardial infarction. It requires quick reflexes and decision-making abilities, which may be impaired during the recovery period. Swimming in a pool, light housework, and walking on flat ground are generally safe and beneficial activities for clients following a myocardial infarction as they promote circulation, muscle strength, and overall well-being.

Correct Answer: A

Rationale: Topping fruits with yogurt is the correct recommendation to increase calorie and protein intake for a client on chemotherapy who is losing weight. Yogurt is a good source of protein and adding it to fruits can provide additional calories as well. Choice B, adding cream to soups, may increase calorie intake but does not specifically address protein needs. Choice C, increasing fluids during meals, is important for hydration but does not directly address calorie and protein intake. Choice D, using milk instead of water in recipes, may increase calorie content but does not focus on increasing protein intake, which is essential for clients on chemotherapy.

Correct Answer: D

Rationale: The correct answer is D: 'Redness, swelling, and warmth at the surgical site.' These are specific signs of infection at the surgical site that a nurse should monitor for in a postoperative patient. While fever, chills, and increased pain can also indicate infection, the most direct signs are redness, swelling, and warmth at the surgical site. Therefore, 'D' is the best choice as it directly relates to the site of the surgery and is crucial to monitor for potential postoperative infections.

Administering IV conscious sedation (Choice D) is a high-risk task that requires advanced skills and should be performed by a registered nurse or higher-level provider.

Correct Answer: A

Rationale: The correct answer is to store the current bottle of insulin at room temperature. Insulin should be stored this way to maintain its potency and effectiveness. Choice B is incorrect because massaging the injection site after removing the needle is not recommended practice and can cause bruising. Choice C is incorrect as pulling back on the plunger after injecting insulin can lead to injecting air bubbles into the tissue. Choice D is incorrect as syringes should not be reused multiple times due to the risk of contamination and inaccurate dosing.
