Correct Answer: A

Rationale: An ankle-foot orthotic is the correct choice to prevent a plantar flexion contracture in a paralyzed limb. An ankle-foot orthotic helps maintain proper alignment of the foot and ankle, preventing the foot from being permanently fixed in a pointed-down position. Continuous passive motion machines are typically used to promote joint movement after surgery and would not address the prevention of contractures in this case. Abduction splints are used to keep the legs apart and would not address the specific issue described. Sequential compression devices are used to prevent deep vein thrombosis by promoting circulation in the lower extremities and are not indicated for preventing plantar flexion contractures.

Correct Answer: D

Rationale: Re-assessing the client's situation before providing care is the most appropriate action in this scenario. By re-evaluating the client, the nurse can better understand the cause of the anxiety and tailor the care accordingly. Diverting the client's attention (Choice A) may not address the underlying issue causing anxiety. Calling for additional help (Choice B) is not the initial step required unless there is an urgent need. Documenting the planned action (Choice C) should come after reassessing the client to ensure accuracy and relevance.

Correct Answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.

Correct Answer: B

Rationale: The correct action is to ask the client if they are having pain. Pain can lead to temporary increases in blood pressure. Addressing pain as a potential cause is the initial step before considering medication adjustments. Requesting an antihypertensive medication or an antianxiety medication without assessing pain first would not address the immediate concern. Returning to recheck the BP can be done after addressing the potential pain issue.

Correct Answer: C

Rationale: The correct position for a client immediately following a liver biopsy is right side-lying with a pillow under the costal margin. This position helps prevent bleeding by applying pressure to the biopsy site. Placing the client supine with the right arm raised above the head (Choice A) or supine with the head of the bed elevated (Choice B) are not ideal positions for post-liver biopsy care as they do not provide the necessary pressure to the biopsy site. Left side-lying with the head of the bed flat (Choice D) is also not recommended as it does not assist in preventing bleeding after a liver biopsy.
