1. Which stoma would you expect a malodorous, enzyme-rich, caustic liquid output that is yellow, green, or brown?
- A. Ileostomy.
- B. Ascending colostomy.
- C. Transverse colostomy.
- D. Descending colostomy.
Correct answer: A
Rationale: An ileostomy would have a malodorous, enzyme-rich, caustic liquid output that is yellow, green, or brown.
2. Your patient with peritonitis is NPO and complaining of thirst. What is your priority?
- A. Increase the I.V. infusion rate.
- B. Use diversion activities.
- C. Provide frequent mouth care.
- D. Give ice chips every 15 minutes.
Correct answer: C
Rationale: The correct answer is C: Provide frequent mouth care. In a patient with peritonitis who is NPO and thirsty, the priority is to maintain oral hygiene and provide comfort by moistening the mouth with frequent mouth care. This helps alleviate the sensation of thirst and maintains oral health. Increasing the IV infusion rate (choice A) may not address the patient's discomfort directly related to thirst. Using diversion activities (choice B) is not as critical as addressing the patient's immediate need for oral care. Giving ice chips every 15 minutes (choice D) is not recommended for a patient with peritonitis who is NPO, as it can lead to complications or worsen the condition.
