مريض بانسداد أمعاء ركب له أنبوب أنفي معدي للتفريغ على شفط متقطع. أي ملاحظة تدل أن العلاج فعال؟

A client with bowel obstruction has an NG tube on intermittent suction. Which finding shows treatment is working?

1. Less distension and nausea, and he starts passing flatus
2. Drainage in the canister suddenly stops completely
3. The abdomen becomes harder and tender to touch
4. Vomiting increases despite the tube

Answer: A) Less distension and nausea, and he starts passing flatus. Effective decompression shows as less distension and nausea and return of flatus. Sudden cessation of drainage may mean a blocked tube; a rigid tender abdomen may mean perforation or strangulation.
