Which practice guideline should the nurse implement when caring for the patient receiving enteral feedings?

A. Gastric residual volumes of 500 mL should be of concern: Residual volumes ≥500 mL are associated with increased risk of aspiration and feeding intolerance. At this threshold, the nurse should reassess feeding tolerance and notify the provider. B. Gastric residual volume is checked every 2 hours: Routine checking every 2 hours is not recommended and may unnecessarily interrupt nutrition. Many guidelines discourage frequent checks unless the patient shows signs of intolerance. C. Gastric residual volumes of 100 mL should be of concern: A residual of 100 mL is generally considered acceptable and not an indication to stop or hold enteral feedings. Using this low threshold can lead to underfeeding. D. Gastric residual volume is checked every 6 hours: Scheduled routine checks at fixed intervals are no longer universally recommended. Assessment should be guided by patient condition and clinical signs rather than strict timing.
