Correct Answer: B

Rationale: The correct answer is B. The CDC guidelines recommend that healthcare workers wear gloves when coming in contact with blood or body fluids from any client since HIV can be infectious before the client becomes aware of their exposure and/or symptomatic. Choice A is incorrect because placing HIV-positive clients in strict isolation and limiting visitors is not a standard practice for HIV infection control. Choice C is incorrect as mandatory HIV testing for those working with AIDS clients is not a CDC recommendation for routine infection control. Choice D is incorrect because freezing HIV blood specimens at -70°F does not kill the virus; HIV can remain infectious even at very low temperatures.

Correct Answer: C

Rationale: The most crucial instruction for a client who has had a total laryngectomy is to carry a medic alert card stating that they are a total neck breather. This is important because if they experience a cardiac arrest, mouth-to-neck breathing may be required. Choice A about carrying suction equipment is not the most critical as the client may not always need it. Choice B is not as essential as having a medic alert card. Choice D is not directly related to the client's safety due to their laryngectomy.

Correct Answer: D

Rationale: In this scenario, the client presents with significant weight loss, poor hygiene, and inadequate clothing, which are concerning signs of self-neglect. Before taking action, it is crucial for the nurse to collect more data to determine the root cause of these issues. Jumping to conclusions or immediately involving social services without a thorough assessment could potentially harm the client or strain relationships. Discussing the need for mental health counseling with the daughter or simply advising the client to take better care of herself may not address the underlying problem of self-neglect. Therefore, the most appropriate initial action is for the nurse to collect further data to make an informed decision before taking the next steps.

Correct Answer: A

Rationale: The correct nursing intervention in this scenario is to assist the client in finding ways to increase his fluid intake. Clients with COPD, including emphysema, should aim to consume at least three liters of fluids per day to help keep their mucus thin. As the disease progresses, these clients may decrease fluid intake due to various reasons. Suggesting creative methods, such as having disposable fruit juices readily available, can help the client meet this goal. Option B is incorrect as seeing an ear, nose, and throat specialist is not directly related to the client's symptoms. Option C is not the priority in this case, as the main concern is addressing the client's dehydration. Option D does not address the immediate need for managing the client's dehydration and is not the most appropriate intervention at this time.

Correct Answer: A

Rationale: The correct answer is A. Potassium level of 6.0 mEq/L indicates hyperkalemia, which is a critical electrolyte imbalance in clients with chronic kidney disease. Hyperkalemia can lead to life-threatening arrhythmias, making it the priority finding to address. Choice B, a daily urine output of 400 ml, may indicate decreased kidney function but does not pose an immediate life-threatening risk compared to hyperkalemia. Peripheral neuropathy (Choice C) and uremic fetor (Choice D) are common manifestations of CKD but are not as urgent as addressing a potentially fatal electrolyte imbalance like hyperkalemia.
