Correct Answer: C

Rationale: Dehydration is the primary factor to consider in this scenario. Dehydration leads to decreased skin turgor and tenting, where the skin does not return to its normal position when pinched. While thin, parchment-like skin, loss of adipose tissue, and diminished skin elasticity can contribute to skin changes, they are not the primary cause of the significant tenting observed.

Correct Answer: B

Rationale: A client who has tuberculosis requires airborne precautions, including placing the client in a room with negative-pressure airflow to reduce the risk of infection transmission. Choices A, C, and D are incorrect. Carrying soiled linens in a mesh bag, providing disposable plates and utensils for an HIV-positive client, and disposing of blood-saturated dressing in a biohazard bag do not specifically address preventing the spread of tuberculosis, which requires airborne precautions.

Correct Answer: A

Rationale: The correct answer is A. Advocacy in nursing involves ensuring clients' safety, health, and rights. Nurses advocate for their clients by promoting autonomy, informed decision-making, and protecting their rights. Choice B is incorrect because advocacy goes beyond just supporting client complaints; it encompasses a broader scope of ensuring holistic care and well-being. Choice C is incorrect as advocacy does not mean making all decisions for the client but rather empowering them to make informed choices. Choice D is incorrect as advocacy is a crucial component of nursing responsibilities, as it involves standing up for clients' best interests and ensuring their rights are respected.

Correct Answer: A

Rationale: To maintain the patency of a nasogastric (NG) tube, it is essential to flush the tube with 30 ml of water before and after medication administration. This action helps ensure that the tube remains open and free from blockages. Flushing the tube prevents any medication residue from causing blockages, maintaining its patency. Choice B is incorrect because administering medication with food does not relate to maintaining tube patency. Choice C is incorrect as verifying tube placement by aspirating stomach contents is related to confirming correct tube placement, not maintaining patency. Choice D is also incorrect because diluting the medication with normal saline is not primarily aimed at maintaining the tube's patency.

Correct Answer: A

Rationale: The correct answer is A: Pain related to ischemia. This nursing diagnosis should have priority because addressing the pain caused by ischemia is crucial in managing the client's myocardial infarction. Pain management is essential not only for the client's comfort but also for improving outcomes and reducing complications. Choices B, C, and D are not the priority in this scenario. Risk for altered elimination: constipation (Choice B) is not as immediate a concern as managing the client's pain. Risk for complication: dysrhythmias (Choice C) may be a potential concern but addressing the client's pain takes precedence. Anxiety related to pain (Choice D) is important to address but should come after managing the pain itself.
