Correct Answer: B

Rationale: Verifying the correct placement of a nasogastric tube before each feeding is essential to prevent aspiration and ensure that the tube is properly positioned in the stomach or intestine. This action is a priority to maintain client safety. Flushing the tube with water every 4 hours is important for tube patency but is not the priority over verifying placement. Securing the tube with tape and keeping the head of the bed elevated are crucial but are considered secondary measures compared to confirming the correct tube placement.

Correct Answer: B

Rationale: The correct recommendation for a client with chronic venous insufficiency to prevent complications is to wear compression stockings. Compression stockings help improve venous circulation and prevent the worsening of symptoms. While elevating the legs is also beneficial, the priority intervention in preventing complications is wearing compression stockings. Using a heating pad on the legs can actually worsen the condition by dilating blood vessels, and massaging the legs daily can potentially damage fragile skin in clients with chronic venous insufficiency.

Correct Answer: C

Rationale: The correct answer is C: Assessing a client's pain level. This task involves clinical judgment and interpretation, which are within the scope of a licensed nurse's practice. Delegating pain assessment to unlicensed personnel could lead to errors in pain management and inappropriate interventions. Choices A, B, and D involve tasks that can be safely delegated to unlicensed assistive personnel as they do not involve interpretation or nursing judgment. Taking a client's blood pressure, providing oral hygiene, and assisting with ambulation are all routine tasks that can be appropriately assigned to UAP under the supervision of a licensed nurse.

Correct Answer: B

Rationale: The correct answer is to assess for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding in patients. Monitoring for signs of bleeding such as easy bruising, petechiae, blood in urine or stool, or unusual bleeding from gums is crucial. Checking the client's blood pressure (choice A) is important but not the priority in this situation. Assessing the client's neurological status (choice C) is essential in stroke patients but is not the priority related to warfarin therapy. Monitoring intake and output (choice D) is important for overall assessment but is not the priority when a client is on warfarin, as assessing for bleeding takes precedence.

Correct Answer: B

Rationale: The correct action for the nurse to take to assess for blanching in an area of hyperemia is to apply light pressure over the area. Blanching is the temporary whitening of the skin when pressure is applied and then released, indicating that the blood flow is returning to the area. Applying light pressure helps in determining if the hyperemic area blanches, ensuring that blood flow is adequate. Choices A, C, and D are incorrect because documenting findings, applying heat, or using cold compresses are not appropriate actions for assessing blanching in an area of hyperemia.
