Correct Answer: C

Rationale: The correct answer is C. In a nonstress test, the client is required to press a handheld button whenever fetal movement is felt, which is then recorded on the monitor. This action helps assess the baby's heart rate in response to its movements, providing valuable information about the baby's well-being. Choices A, B, and D are incorrect because the nonstress test does not involve determining the length of the cervix, monitoring blood pressure, or being completed in 5 minutes. These aspects are not part of the nonstress testing procedure and are unrelated to the purpose of the test.

Correct Answer: A

Rationale: The correct answer is a low-protein diet for a patient with chronic kidney disease. In chronic kidney disease, the kidneys may have difficulty filtering waste products from protein metabolism, leading to a buildup of toxins in the body. Therefore, reducing protein intake can help lessen the workload on the kidneys. Choices B, C, and D are incorrect. A high-protein diet would increase the workload on the kidneys, while a low-sodium diet is beneficial for conditions like hypertension or heart failure but not specifically targeted for chronic kidney disease. A high-sodium diet can worsen fluid retention and hypertension in patients with kidney disease.

Correct Answer: D

Rationale: When a client refuses medication, the nurse should inform the client of the possible consequences of refusal. This action helps the client understand the risks associated with not taking the medication. Asking the client to discuss their feelings (choice A) is important but should follow after informing them of the consequences. Explaining the importance of the medications (choice B) might not address the immediate concern of the client. Documenting the refusal and withholding the medication (choice C) should be done after informing the client of the consequences and attempting to address their concerns.

Correct Answer: C

Rationale: The correct instruction is to apply the prosthesis immediately upon waking each day. This helps the client adjust to and maintain mobility. Choice A is incorrect because wearing the prosthesis for only 2 hours at a time may not be sufficient for proper adjustment. Choice B is incorrect as removing the prosthesis every other day is not a standard practice and may hinder the client's mobility. Choice D is incorrect because elevating the stump for 24 hours after applying the prosthesis is unnecessary and not a recommended practice.

Correct Answer: A

Rationale: Muscle weakness is a characteristic finding in hyperkalemia. High levels of potassium can affect the normal function of muscles, leading to weakness. Nausea and increased thirst are not typically associated with hyperkalemia. Restlessness is more commonly seen in conditions such as hypoxia or anxiety, not specifically in hyperkalemia.
