Which of the following observations indicates that a patient might tolerate ice chips after surgery?

The indication that a patient might tolerate ice chips after surgery is linked to the presence of active bowel sounds. Active bowel sounds suggest that the gastrointestinal system is returning to function, which is a positive sign that the patient may be able to handle oral intake, even if it begins with something as gentle as ice chips.

In post-operative care, it is essential to assess the functioning of the digestive system before advancing a patient's diet. Active bowel sounds usually indicate that peristalsis is occurring, which means the intestines are working properly and could manage the introduction of small amounts of fluid or food.

Other observations, such as complaints of nausea or absence of flatulence, indicate potential gastrointestinal disturbances, which may warrant caution in advancing the diet. A feeling of thirst, while indicative of a desire for fluids, does not provide sufficient information about the patient's ability to tolerate them safely. Therefore, the presence of active bowel sounds is the most reliable indicator for starting ice chips post-surgery.
