Correct Answer: B

Rationale: The most effective intervention for managing constipation in a patient is to administer a stool softener as prescribed. Stool softeners help relieve constipation by making the stool easier to pass, especially in postoperative patients. Increasing fluid intake can be beneficial but may not address the underlying cause of constipation. While a high-fiber diet is important for bowel health, it may not provide immediate relief for constipation. Teaching a patient to perform Valsalva maneuvers is not recommended for managing constipation as it can lead to adverse effects like increasing intra-abdominal pressure.

Correct Answer: B

Rationale: The correct method to reduce the risk of infection when handling a urinary catheter is to maintain sterile technique when inserting the catheter. Sterile technique helps prevent introducing pathogens into the urinary system, reducing the risk of infection. Choice A is incorrect because cleaning the catheter tubing with soap and water is not sufficient for preventing infection. Choice C is incorrect as clean gloves and technique are not enough; sterile technique is necessary. Choice D is incorrect as flushing the catheter tubing with sterile water, though important for maintaining catheter patency, does not address the need for sterile technique during insertion to prevent infection.

Correct Answer: B

Rationale: In this scenario, with no DNR order in place and the client not breathing, the nurse should initiate CPR and call for emergency assistance. Option A is incorrect as immediate action is required in the absence of breathing. Option C is incorrect as the nurse should act promptly to provide life-saving measures. Option D is incorrect because the nurse's primary duty is to provide care in the absence of a directive preventing intervention.

Correct Answer: A

Rationale: Using sterile gloves during catheter insertion is crucial to prevent infection. Sterile gloves help maintain asepsis during the procedure, reducing the risk of introducing microorganisms into the urinary tract. Cleaning the insertion site with alcohol, as mentioned in choice B, is important but not as critical as using sterile gloves. Choice C, inserting the catheter as quickly as possible, is not recommended as it can lead to errors and increase the risk of contamination. Choice D, using a smaller catheter size to minimize trauma, is not directly related to preventing infection but rather focuses on patient comfort and reducing tissue damage.

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.
