On the day of surgery, a client with diabetes who takes insulin on a sliding scale is ordered to have nothing by mouth and all medications withheld. The client's 6 a.m. glucose level is 300 mg/dL. The nurse should:
- A. Withhold all medications as ordered.
- B. Administer the insulin dose dictated by the sliding scale.
- C. Call the physician for specific orders based on the glucose level.
- D. Notify the surgery department.
Correct Answer: C
Rationale: A glucose level of 300 mg/dL indicates significant hyperglycemia, which poses risks during surgery. Calling the physician for specific orders ensures appropriate insulin administration while adhering to NPO and surgical protocols.

The client asks the nurse, 'Why can't the doctor tell me exactly how much of my leg they're going to take off? Don't you think I should know that?' The nurse responds, knowing that the final decision on the level of the amputation will depend primarily on:
- A. The need to remove as much of the leg as possible
- B. The adequacy of the blood supply to the tissues
- C. The ease with which a prosthesis can be fitted
- D. The client's ability to walk with a prosthesis
Correct Answer: B
Rationale: The level of amputation depends primarily on the adequacy of blood supply to the tissues, as determined intraoperatively. Sufficient perfusion is necessary for healing and preventing further necrosis. Removing excess tissue, prosthesis fitting, or walking ability are secondary considerations.
