Correct Answer: A

Rationale: The correct answer is A: Administer analgesics regularly. Postoperative pain management often requires a scheduled, around-the-clock administration of analgesics to maintain a consistent level of pain relief and minimize the risk of breakthrough pain. Choice B, administering pain medication PRN (as needed), may lead to inadequate pain control as the medication is not given preemptively. Choice C, encouraging deep breathing exercises, can be beneficial for pain management but should be used as an adjunct to analgesic therapy. Choice D, providing distraction techniques, may help some patients cope with pain but should not be the primary method of pain management postoperatively.

Correct Answer: C

Rationale: The correct answer is C because checking blood sugar levels every morning before breakfast is a crucial aspect of managing diabetes effectively. This practice helps individuals monitor their blood sugar levels regularly and adjust their treatment plan as needed. Option A is incorrect as consuming a bedtime snack based on blood sugar levels alone may not be an appropriate approach to managing diabetes. Option B is incorrect as relying on more sugar-free candy does not address the overall dietary management of blood sugar levels. Option D is incorrect as avoiding physical activity when blood sugar is below 100 mg/dL can hinder diabetes management, as exercise is generally beneficial for controlling blood sugar levels.

Correct Answer: C

Rationale: The correct answer is to monitor aPTT for a patient receiving heparin therapy. The activated partial thromboplastin time (aPTT) is used to assess and adjust heparin dosage to ensure the patient is within the therapeutic range for anticoagulation. Monitoring the aPTT helps in preventing both clotting and bleeding complications. Platelet count (Choice A) is important to monitor for patients receiving antiplatelet therapy, not heparin. PT/INR (Choice B) is typically monitored for patients on warfarin therapy, not heparin. Monitoring the complete blood count (CBC) (Choice D) is essential for various conditions but is not specific to monitoring heparin therapy.

Correct Answer: A

Rationale: Corrected Rationale: Changing the central line dressing daily is crucial in preventing infection at the insertion site. This practice helps maintain a clean and sterile environment around the central line, reducing the risk of pathogens entering the bloodstream. Monitoring for redness (choice B) is important but may not directly prevent infection. Checking the central line site every shift (choice C) is essential for early detection of any issues but does not solely prevent infection. Flushing the line with saline (choice D) is a necessary procedure for maintaining central line patency but does not primarily prevent infection.

Correct Answer: D

Rationale: The correct answer is to apply a hydrocolloid dressing. For a stage 2 pressure injury, maintaining a moist environment is crucial for healing. Hydrocolloid dressings help achieve this by promoting autolytic debridement and creating a barrier against bacteria while allowing the wound to heal. Applying a dry dressing (Choice A) may not provide the necessary moisture for healing. Cleansing the wound with normal saline (Choice B) is essential, but a hydrocolloid dressing is more specific for promoting healing in this case. Performing debridement as needed (Choice C) is not typically indicated for stage 2 pressure injuries, as they involve partial-thickness skin loss without slough or eschar.
