A nurse is preparing to assist a provider with the insertion of a nontunneled percutaneous central venous catheter into a client's subclavian vein. Which of the following actions should the nurse take?

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: C

Rationale: The correct instruction the nurse should include is to advise the client to eat foods that are rich in potassium. Furosemide is a loop diuretic that can cause the loss of potassium, leading to hypokalemia. Eating foods high in potassium can help prevent this electrolyte imbalance. Choice A is incorrect because furosemide does not directly interact with magnesium. Choice B is incorrect because furosemide is usually taken in the morning to prevent nighttime diuresis. Choice D is incorrect because furosemide is a diuretic that typically leads to a decrease in blood pressure rather than an increase.

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: D

Rationale: The correct statement to include in the teaching about amniocentesis is that the client should report if they experience any contractions after the procedure. This is crucial because contractions could indicate preterm labor or other complications following the amniocentesis. Choices A and B are incorrect as a full bladder is not required for the procedure, and magnesium sulfate is not typically given before an amniocentesis. Choice C is incorrect as the procedure usually takes about 20-30 minutes to complete.

Correct Answer: B

Rationale: In end-stage liver disease, the liver's inability to convert ammonia into urea leads to elevated ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Therefore, the correct answer is B. Elevated albumin (Choice A) is not typically seen in end-stage liver disease as liver dysfunction often leads to decreased albumin levels. Decreased total bilirubin (Choice C) is unlikely in end-stage liver disease, as bilirubin levels tend to be elevated due to impaired liver function. Decreased prothrombin time (Choice D) is also not expected in end-stage liver disease, as impaired liver function results in prolonged prothrombin time.
