When caring for a patient with a colostomy, which nursing action is most important?

Correct Answer: B

Rationale: Emptying the colostomy bag when it is half full is the most important nursing action when caring for a patient with a colostomy. This practice helps prevent leakage, reduces the risk of skin irritation, and promotes patient comfort. Monitoring for signs of infection (Choice A) is essential but not as crucial as maintaining proper colostomy care. Encouraging the patient to eat smaller, more frequent meals (Choice C) can be beneficial for colostomy patients but is not as critical as ensuring timely emptying of the colostomy bag. Applying a skin barrier to prevent irritation (Choice D) is important, but ensuring timely emptying of the colostomy bag takes precedence in preventing complications associated with a colostomy.

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: 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: A

Rationale: The most important instruction to provide when teaching a patient about self-administration of insulin is to rotate injection sites to prevent tissue damage. Rotating injection sites helps prevent lipodystrophy (tissue damage) and ensures proper insulin absorption. Option B is incorrect because the angle of insulin injection varies depending on the patient's body composition. Injecting at a 90-degree angle is not always necessary. Option C is not the most crucial instruction; while storing insulin in the refrigerator is important, it is not the priority when teaching self-administration. Option D is also important for maintaining consistency but is not as critical as rotating injection sites to prevent tissue damage.

Correct Answer: B

Rationale: The most effective intervention in managing a patient with chronic pain is teaching the patient relaxation techniques. Relaxation techniques can help reduce stress, decrease muscle tension, and improve pain management in patients with chronic pain. Administering opioids as prescribed may have risks of dependence and side effects, making it less favorable as a first-line intervention. Encouraging range of motion exercises can be beneficial, but relaxation techniques directly target stress reduction, a common exacerbating factor in chronic pain. Recommending complete bed rest is generally discouraged in chronic pain management as it can lead to deconditioning and worsen pain over time.
