Question

before administering an intermittent tube feeding through a nasogastric tube, the nurse checks for gastric residual volume. which is the best rationale for checking gastric residual volume before administering the tube feeding? answer options: 1 observe the digestion of formula 2 check fluid and electrolyte status 3 evaluate absorption of the last feeding 4 confirm proper nasogastric tube placement

Explanation:

Checking gastric residual volume helps determine if the previous feeding has been absorbed. High residual volume may indicate poor absorption and potential risk of aspiration or over - feeding. It is not mainly for observing formula digestion, checking fluid/electrolyte status, or confirming tube placement.

Answer:

1. Evaluate absorption of the last feeding
