Correct Answer: D

Rationale: The correct answer is to monitor food intake and behavior for one hour after meals. This is crucial in caring for a client with an eating disorder as it helps in assessing any immediate risks related to the disorder. Option A is incorrect as it may trigger additional stress for the client and distract from the main focus of managing the disorder. Option B, weighing the client daily, could lead to an unhealthy focus on weight and potentially worsen the client's mental health. Option C, restricting access to mirrors, although it may be beneficial for body image concerns, does not directly address the core issue of monitoring food intake and behavior, which is essential in managing eating disorders.

Correct Answer: C

Rationale: The correct first action for the nurse is to inspect the IV site. This is important to assess for any signs of infiltration or extravasation, which could be causing the burning sensation. Aspirating the IV site for blood return (Choice A) may not be the initial priority as it does not directly address the client's complaint of burning. Slowing the infusion (Choice B) may help alleviate discomfort but should not be done before inspecting the site. Stopping the infusion (Choice D) may be necessary, but inspecting the site should come first to determine the appropriate course of action.

Correct Answer: A

Rationale: During a fire emergency, the priority is the safety of the individual in the room where the fire is located. Removing the client from the room immediately is the first step in the RACE acronym for fire safety: Rescue/Remove, Alarm, Contain, and Extinguish. This action ensures the client's safety before addressing the fire itself. Choice B is incorrect as leaving the client's room to obtain a fire extinguisher can delay the immediate removal of the client from the danger. Choice C is incorrect as pulling the fire alarm should be done after ensuring the client's safety. Choice D is incorrect as evacuating all clients from the unit should come after ensuring the safety of the individual in immediate danger.

Correct Answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.

Correct Answer: A

Rationale: The correct answer is wearing clean gloves while performing a heel stick on an infant. Standard precautions require the use of gloves when there is a risk of exposure to blood or body fluids. Clean gloves are suitable for this task as they provide adequate protection without being sterile. Choice B is incorrect because wearing the same gloves for different clients can lead to cross-contamination, violating standard precautions. Choice C is incorrect as sterile gloves are usually not required for changing a urine bag and nasogastric canister unless a specific aseptic technique is indicated; standard precautions do not demand sterile gloves for such tasks. Choice D is incorrect as donning a gown is not necessary for checking an IV pump unless there is a risk of exposure to bodily fluids that would necessitate full-body protection, which is not indicated in this scenario.
