Correct Answer: A

Rationale: The correct answer is A: 'Dangle the patient at the bedside.' When a patient has been in bed for an extended period and needs to be ambulated, it is essential to dangle the patient at the bedside first. Dangling involves helping the patient sit on the edge of the bed with their legs over the side before standing up. This action helps prevent orthostatic hypotension, a sudden drop in blood pressure when moving from lying down to standing up, which can lead to dizziness or fainting. Encouraging isometric exercises (choice B) or suggesting a high-calcium diet (choice C) are not the first actions to take before ambulating a patient. Maintaining a narrow base of support (choice D) is related to assisting with ambulation but is not the initial step that should be taken.

Correct Answer: B

Rationale: Checking the placement of the NG tube before each feeding is crucial as it ensures the tube is correctly positioned, reducing the risk of complications such as aspiration or improper delivery of feedings. Flushing the NG tube with water before and after each feeding can disrupt the feeding schedule and is not a standard procedure. Administering medications through the NG tube every 4 hours may not be necessary for all patients and should be based on specific medication requirements. Increasing the feeding rate without proper assessment and monitoring can lead to feeding intolerance or complications, making it an inappropriate intervention.

Correct Answer: B

Rationale: The correct answer is B. Nurses have a legal and ethical obligation to honor a client's do-not-resuscitate (DNR) order, regardless of any request for resuscitation during a family visit. It is crucial for the nurse to explain to the client that the DNR order must be respected. Choice A is incorrect because starting resuscitation against the client's documented wishes goes against the principle of autonomy. Choice C is inappropriate as it disregards the client's autonomy and legal directives. Choice D is not the best option as the nurse should prioritize honoring the client's decision as per the DNR order.

Correct Answer: B

Rationale: The nurse's priority action should be to withhold the medication until the trough level is obtained. This is crucial to ensure accurate dosing based on the patient's levels. Administering the medication before the peak level is obtained (choice A) can lead to incorrect dosing. Administering the medication based on the previous trough level (choice C) may not reflect the current levels accurately. Ensuring that the medication is administered within 2 hours of the peak level (choice D) is not necessary for obtaining accurate peak and trough levels.

Correct Answer: B

Rationale: Encouraging stretching exercises is the most appropriate nursing intervention to help a patient with chronic pain maintain mobility. Stretching exercises can improve flexibility, prevent stiffness, and promote better range of motion in patients with chronic pain. Providing opioids (Choice A) may help control pain but does not directly address mobility. Teaching the patient to use assistive devices (Choice C) may be beneficial but does not focus on improving mobility directly. Recommending complete bed rest (Choice D) can lead to deconditioning and further loss of mobility, which is not recommended for chronic pain management.
