Correct Answer: B

Rationale: Asking the client what the voices are saying is the priority action as it helps assess the content of the hallucinations. This assessment is crucial to determine if the client is at risk of harm to themselves or others. Encouraging the client to listen to music or providing a distraction may not address the underlying issues related to the hallucinations. Administering antipsychotic medication, although important, should come after a thorough assessment of the hallucinations to ensure the right medication and dosage are provided.

Correct Answer: A

Rationale: The correct answer is to ensure that electrical cords are not frayed. Frayed electrical cords pose a fire hazard when oxygen is in use. Keeping oxygen tanks in a horizontal position (Choice B) is important to prevent leaks but is not the priority compared to fire safety. Storing extra oxygen tanks in a closed closet (Choice C) is also important but not as immediate as preventing fire hazards. Applying petroleum-based gel to the inside of the nostrils (Choice D) is unrelated to oxygen therapy safety and is not recommended.

Correct Answer: A

Rationale: The correct answer is A: 'If I eat 500 fewer calories per day, I should lose 1 pound per week.' This statement is accurate because a reduction of 500 calories per day typically results in a weight loss of 1 pound per week. This is based on the principle that a calorie deficit of 3,500 calories equals about 1 pound of body fat. Choices B, C, and D are incorrect because they do not align with the established relationship between calorie reduction and weight loss. Eating 450 fewer calories per day would not lead to a weight loss of 2 pounds per week; similarly, reducing calories by 250 or 300 per day would not result in losing 2 pounds or 1 pound per week, respectively.

Correct Answer: B

Rationale: The correct action for the nurse to take when assisting with the insertion of a nontunneled percutaneous central venous catheter into the subclavian vein is to place the client in Trendelenburg position. This position helps distend the veins and reduces the risk of air embolism during the insertion procedure. Option A, positioning the client in a high-Fowler's position, would not be appropriate as it does not facilitate venous distention. Option C, placing a rolled towel under the client's neck, is not directly related to the procedure and does not serve a specific purpose in this context. Option D, assisting the client into a side-lying position, is also not the correct choice as Trendelenburg position is preferred for this procedure to aid in vein distention.

Correct Answer: D

Rationale: The correct action for the nurse to take first is to ask the family what the provider has discussed with them. This allows the nurse to clarify any misunderstandings and ensures that the family is fully informed before providing further information. Option A is not the best choice because it assumes the need for more information without first understanding what has already been communicated. Option B is premature as the family may not be ready for grief counseling at this stage. Option C, although a good general practice, is not the most appropriate immediate action in this situation where clarifying existing information is crucial.
