Adult Health Exam 1

Correct Answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

Correct Answer: D

Rationale: Providing preoperative teaching for a client undergoing a thyroidectomy is essential to prepare them for postoperative care. Information about the importance of maintaining neck stability is crucial to prevent complications such as strain on the surgical site. Teaching the client how to care for the surgical drain is important to prevent infections, ensure proper wound healing, and aid in monitoring postoperative recovery. Pain management strategies are vital to ensure the client's comfort and promote optimal recovery. Including all these aspects in preoperative teaching ensures the client is well-prepared for comprehensive postoperative care. Therefore, the correct answer is D because all these elements are essential components of postoperative care for a client undergoing a thyroidectomy. Choices A, B, and C are all important aspects of postoperative care that the nurse should include in the preoperative teaching session.

Correct Answer: B

Rationale: Maintaining hip abduction with pillows is crucial in preventing dislocation of the hip prosthesis postoperatively. This position helps keep the hip joint stable and reduces the risk of the prosthesis becoming displaced. Choices A, C, and D are not as effective in preventing dislocation. Keeping the client in a low Fowler's position does not provide the necessary hip support. While early ambulation is important for circulation and preventing complications, maintaining hip abduction is more specific to preventing prosthesis dislocation. Placing the client in a prone position can increase the risk of hip prosthesis dislocation due to the extreme positioning.

Correct Answer: B

Rationale: When a client presents with a severe headache, the initial action should be to check their blood pressure. This step is crucial as it can help determine if the headache is related to hypertension or other cardiovascular issues. Administering pain relief medication should only be done after assessing the client's vital signs and confirming the cause of the headache. While assessing for associated symptoms like nausea or photophobia is important for a comprehensive evaluation, it should follow checking the blood pressure to address immediate concerns. Offering a quiet environment is indeed beneficial for the client's comfort, but it is not the priority when dealing with a severe headache.
