A nurse is caring for a client who has named a person to serve as his health care proxy. The client talks about this type of advance directives. Which of the following statements by the client indicates a need for clarification?

Answer: D

Rationale:

A. "Drink 400 ml every hour until bowel movements are clear": The standard recommendation for PEG is to drink a specific volume, usually 240 ml every 10 to 15 minutes, rather than 400 ml every hour. The goal is to ensure the bowel is adequately cleansed, and this rate is typically more effective in achieving that.

B. "Expect bowel movements to begin 3 hr following completion of solution": Bowel movements often start within an hour or two after starting the PEG solution rather than waiting for 3 hours after finishing it. The timing can vary, but the onset is generally sooner.

C. "To prevent dehydration, drink an additional liter of fluid during preparation time": While it is important to stay hydrated, the specific recommendation for additional fluid intake beyond the PEG solution can vary. Typically, the instructions focus on the volume of PEG solution to drink rather than specifying a set amount of additional fluid.

D. "Abdominal bloating might occur": Abdominal bloating is a common side effect of bowel cleansing preparations like PEG. It can occur due to the large volume of fluid ingested and the rapid movement of the bowel contents, making it a relevant point to include in the instructions.

Answer: B

Rationale:

A. Radial vein in the wrist: The radial vein is not commonly used for IV catheter insertion due to its location and size. The wrist veins can be smaller and more difficult to cannulate compared to veins in the forearm or antecubital area.

B. Median vein in the forearm: The median vein in the forearm is a preferred site for IV catheter insertion in older adults. It is generally more accessible and less prone to complications than veins in the hand or wrist, making it a suitable choice for stable, longer-term access.

C. Dorsal metacarpal vein: While the dorsal metacarpal veins on the hand can be used for IV insertion, they are typically smaller and more difficult to access than veins in the forearm. Additionally, veins in the hand can be more prone to irritation and complications.

D. Ante-cubital vein: The antecubital vein (such as the median cubital vein) is a good site for IV insertion due to its size and accessibility, especially for larger gauge catheters or when longer-term access is needed. However, it is often preferred for more acute situations rather than routine outpatient procedures.
