Correct Answer: B

Rationale: The correct answer is B: Water. Giving sips of water can help dilute the drain cleaner while waiting for emergency transport, which may help reduce the potential harm caused by the ingestion. Choices A, C, and D are incorrect because tea, milk, and soda can interact with the chemicals in the drain cleaner or increase the risk of vomiting, which is not recommended in this situation.

Correct Answer: A

Rationale: The correct action for the nurse to take when applying a thigh-length sequential compression device to a postoperative client is to ensure that two fingers can fit under the sleeves. This action helps prevent the device from being too tight, which could impede circulation. Choice B is incorrect because the device should not be too tight, as it could lead to circulation issues. Choice C is incorrect as the client should be in a comfortable position, not necessarily supine. Choice D is incorrect as sequential compression devices are typically used continuously to prevent blood clots.

Correct Answer: A

Rationale: During passive range of motion (ROM) exercises, the nurse is responsible for moving the patient's joints through their range of motion. The correct technique involves performing movements slowly and smoothly, only going to the point of resistance without causing pain. This technique helps maintain joint flexibility and prevent contractures. Choice A is the correct answer as it reflects the appropriate technique for passive ROM exercises. Choices B and C are incorrect because the patient is not actively participating, and ROM exercises should not cause pain. Choice D is incorrect as movements should be done deliberately and not quickly.

Correct Answer: A

Rationale: During a seizure, the priority is to lower the client to the floor to prevent injury and ensure their safety. Placing a pad under the client's head helps protect the head from injury. Choice B, holding the client's head still, is incorrect as it can lead to harm; it's essential to allow movement during a seizure to prevent neck injury. Choice C, restraining the client, is dangerous and can cause harm by restricting movement. Choice D, placing the client in a supine position, is also not recommended during a seizure as it does not provide adequate protection for the client.

Correct Answer: B

Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the increased risk of hyperglycemia associated with TPN infusion. Elevated blood glucose levels can lead to complications such as hyperglycemia, which can be harmful to the client. While monitoring serum potassium (Choice A), serum sodium (Choice C), and serum calcium (Choice D) are also important aspects of care, when specifically considering TPN administration, blood glucose monitoring takes precedence due to the potential for significant complications related to glucose imbalances.
