Which intervention is most effective in preventing deep vein thrombosis (DVT) in a postoperative patient?

Correct Answer: B

Rationale: The most effective intervention in preventing deep vein thrombosis (DVT) in a postoperative patient is to encourage early ambulation and leg exercises. Early ambulation helps promote circulation, preventing stasis and reducing the risk of blood clot formation. Encouraging the patient to drink plenty of fluids (choice A) is important for overall health but is not the most effective intervention for preventing DVT. Administering anticoagulants (choice C) is a valuable intervention in some cases, but it may not be suitable for all postoperative patients. Applying compression stockings (choice D) can help prevent DVT but is generally not as effective as early ambulation and leg exercises in postoperative patients.

Correct Answer: C

Rationale: Elevating the head of the bed to 30-45 degrees is the most appropriate intervention to prevent aspiration in a patient with an NG tube. This position helps reduce the risk of regurgitation and aspiration by promoting the proper flow of contents through the gastrointestinal tract and minimizing the chances of stomach contents entering the airway. Flushing the NG tube with water before each feeding may not directly prevent aspiration. Checking the placement of the NG tube is important but does not specifically address the prevention of aspiration. Providing oral care every 4 hours is essential for maintaining oral hygiene but is not directly related to preventing aspiration in a patient with an NG tube.

Correct Answer: B

Rationale: When a client with a history of substance abuse requests pain medication, the nurse should first assess the patient's pain level. It is important to determine the nature and intensity of the pain before administering any medication to ensure appropriate pain management. Administering medication without assessing the pain level can lead to unnecessary drug administration or inadequate pain relief. Administering a placebo would be unethical and ineffective. Refusing to give any medication without proper assessment can compromise the client's comfort and recovery. Therefore, the correct approach is to assess the patient's pain level first before deciding on the most suitable pain management intervention.

Correct Answer: C

Rationale: The appropriate action when a client is wearing a necklace before surgery is to ask the patient for permission to lock it in a safe. This is in line with hospital policy to secure valuables before entering surgery. Choice A is incorrect because simply placing the necklace in a drawer may not be secure. Choice B is incorrect as taping the necklace to the patient's skin can cause skin irritation and is not a standard practice. Choice D is incorrect because the responsibility for securing valuables typically lies with the healthcare team, not the patient's family.

Correct Answer: B

Rationale: The correct first step for a healthcare professional who suspects a colleague of diverting narcotics is to report the suspicion to the supervisor. This action is essential to protect patient safety, uphold ethical standards, and comply with legal obligations. Confronting the colleague directly may not only escalate the situation but also jeopardize the investigation process. Ignoring the issue and continuing to work could potentially harm patients and violate professional responsibilities. Notifying the pharmacy, while important, should come after informing the appropriate supervisor or authority within the healthcare facility.
