2. hyperglycemia.
3. urine formation.
4. aspiration.
Answer: 4
1. Abdominal cramping would not be life-threatening.
2. Tea would not cause hyperglycemia.
3. It would not be desirable to prevent urine formation.
4. Keeping a client NPO for at least 8-10 hours prior to surgery reduces the risk of aspirating stomach contents.
