Correct Answer: D

Rationale: Referring the client to a weight-loss support group is the most appropriate action for a client with a body mass index of 28. This action can provide the necessary support, guidance, and motivation to help the client achieve their weight loss goals. Encouraging the client to continue their current daily caloric intake (Choice A) may not address the need for weight loss. Recommending a total fiber intake of 12g per day (Choice B) is important for overall health but may not directly address weight loss. Advising the client to add 500 calories per day to their diet (Choice C) would not be beneficial for weight loss in this scenario.

Correct Answer: B

Rationale: Offering mouth rinses with normal saline and water is an appropriate intervention for a nurse caring for a patient with stomatitis following radiation treatment. This intervention can help soothe and clean the mouth, promoting comfort and oral hygiene. Choice A is incorrect because serving foods without sauces or gravies does not directly address the client's stomatitis. Choice C is incorrect because serving hot foods can exacerbate discomfort in the client's mouth. Choice D is incorrect because using a straw can help in preventing further irritation in the client's mouth.

Correct Answer: B

Rationale: To prevent clogging when using high-viscosity formulas in a small-bore jejunostomy, the nurse should flush the tubing with 10 mL of water every 6 hours. This action helps maintain tube patency and prevent blockages. Replacing the bag and tubing every 24 hours (Choice A) is unnecessary and does not specifically address preventing clogging. Administering the feeding by gravity drip (Choice C) or heating the formula prior to infusion (Choice D) are not effective interventions for preventing tubing clogging.

Correct Answer: C

Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.

Correct Answer: C

Rationale: The correct answer is C: 'Wrap gloved fingers with gauze to remove dentures.' This method provides a safe and effective way to remove dentures without causing damage. Choice A is incorrect because flossing dentures is not recommended. Choice B is incorrect as it suggests wiping dentures and storing them dry, which is not the best practice. Choice D is incorrect because using a washcloth may not effectively clean all denture surfaces.
