ATI n200 Med Surg Exam 6 Questions
Extract:
Question 1 of 5
Which finding would most concern the nurse when caring for a client diagnosed with a bowel obstruction?
Correct Answer: D
Rationale: Frank blood in the N/G suction container indicates possible bowel ischemia or perforation, which requires immediate intervention and is the most concerning finding. Urine specific gravity of 1.035 suggests dehydration, which is concerning but less urgent. Colicky pain is expected in bowel obstruction, and mild hyponatremia (serum sodium 132 mEq/L) is not immediately life-threatening.
Question 2 of 5
Which sign or symptom would the nurse expect to find in a client diagnosed with ulcerative colitis?
Correct Answer: A
Rationale: Frequent liquid, bloody stools are a hallmark of ulcerative colitis due to colon inflammation. A hard abdomen, low-grade fever, and urinary incontinence are less specific or unrelated.
Question 3 of 5
The nurse suspects that the client hospitalized with severe ulcerative colitis, may be developing the complication of toxic megacolon. Which assessment finding supports these suspicions?
Correct Answer: C
Rationale: An enlarging abdominal girth indicates distension, a key sign of toxic megacolon due to colonic dilation. Tenesmus, hyperactive bowel sounds, and anal fissures are associated with ulcerative colitis or other conditions but are not specific to toxic megacolon.
Question 4 of 5
Two nurses are confirming the dose of an insulin infusion for a client in DKA. The current rate of the client's infusion is 13 mL/hr. At this institution, continuous insulin infusions are mixed with 75 units of insulin in 150 mL of normal saline. What dose (units/hour) is the client currently receiving? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 6.5
Rationale: Insulin concentration is 75 units/150 mL = 0.5 units/mL. At 13 mL/hr, the dose is 0.5 × 13 = 6.5 units/hr.
Question 5 of 5
The client with irritable bowel disease (IBD) is prescribed sulfasalazine, a sulfonamide antibiotic. Which intervention should the nurse implement when administering the medication?
Correct Answer: B
Rationale: Adequate hydration (2000 mL daily) prevents crystalluria and kidney stones, a side effect of sulfasalazine. Bruising, once-daily dosing, and stool assessment are not primary concerns.
