Correct Answer: C

Rationale: The correct answer is C: 'Take prescribed antihypertensive medications daily.' When providing discharge teaching to a client with hypertension, one of the key instructions is to ensure the consistent intake of prescribed antihypertensive medications. This is crucial for controlling blood pressure levels and reducing the risk of complications associated with hypertension. Choices A, B, and D are incorrect because reducing sodium intake, avoiding foods high in potassium, and limiting fluid intake are important dietary modifications for various health conditions, but they are not the priority when it comes to managing hypertension. The primary focus should be on medication adherence to effectively manage hypertension.

Correct Answer: B

Rationale: The nurse's priority action when finding a client experiencing a seizure is to place the client on their side. This action helps maintain an open airway and prevents aspiration, which is crucial during a seizure. Applying oxygen may be necessary after ensuring a patent airway, while administering an anticonvulsant is not within the nurse's scope of practice during an acute seizure. Notifying the provider can be done after ensuring the client's immediate safety.

Correct Answer: B

Rationale: The correct answer is to discontinue the IV line. The client's symptoms of a burning sensation, redness, and swelling at the IV site indicate phlebitis, which is inflammation of the vein. The priority action in this situation is to remove the source of irritation, which is the IV line, to prevent further complications such as infection or thrombosis. Applying a cold compress may provide temporary relief but does not address the underlying issue. Elevating the limb is not the priority in this case. Increasing the IV flow rate can worsen the phlebitis by causing further irritation to the vein.

Correct Answer: B

Rationale: The correct answer is B. Wearing cotton socks is essential for clients with diabetes as it helps protect the feet and reduces the risk of skin breakdown. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage. Choice C is incorrect as clients with diabetes should cut their toenails straight across to prevent ingrown toenails. Choice D is incorrect as applying lotion between the toes can create a moist environment that may increase the risk of fungal infections.

Correct Answer: D

Rationale: The correct answer is D: Lowered immune function. Older adults often experience a decline in immune function as they age, making them more vulnerable to infections. This weakened immune system can result in increased susceptibility to various pathogens. Choice A, 'Improved nutritional status,' is incorrect because good nutrition can actually help support the immune system. Choice B, 'Increased mobility,' is not directly related to an increased risk of infections. Choice C, 'Chronic conditions,' while they can contribute to a weakened immune system, do not directly address the primary risk factor for infections in older adults.
