A patient in the intensive care unit has a nasogastric tube and is also receiving a proton pump inhibitor (PPI). The nurse recognizes that the purpose of the PPI is which effect?
- A. Prevent stress ulcers.
- B. Reduce bacteria levels in the stomach.
- C. Reduce gastric gas formation (flatulence).
- D. Promote gastric motility.
Correct Answer: A
Rationale: Stress-related mucosal damage is an important issue for critically ill patients. Stress ulcer prophylaxis (or therapy to prevent severe gastrointestinal [GI] damage) is undertaken in almost every critically ill patient in an intensive care unit and for many patients on general medical surgical units. Guidelines suggest that all such patients receive either a histamine receptor-blocking drug or a proton pump inhibitor.

A patient will be receiving pantoprazole, 20 mg IV daily every morning. The medication, once reconstituted, has a strength of 40 mg/10 mL. Identify how many milliliters the nurse will draw up for this dose.
