ATI n200 Med Surg Exam 6 Questions
Extract:
Question 1 of 5
The nurse begins a 1000 mL bag of DS 0.45 Saline plus 20 meq of KCl at 125 mL per hour at 1400. The IV is stopped due to signs of infiltration at 1930. How many milliliters will have infused during that time period? Round to the nearest whole number. Do not use trailing zeros.
Correct Answer: 688
Rationale: From 1400 to 1930 is 5.5 hours (330 minutes). At 125 mL/hour, the total volume infused is 125 × 5.5 = 687.5 mL, rounded to 688 mL.
Question 2 of 5
After vertical banded gastroplasty, a 42-year-old male client returns to the surgical nursing unit with a nasogastric tube to low, intermittent suction and a client-controlled analgesia (PCA) machine for pain control. Which nursing action should be included in the postoperative plan of care?
Correct Answer: D
Rationale: Splinting during deep breathing/coughing prevents atelectasis and protects the incision. Juices, frequent NGT irrigation, and PCA warnings are inappropriate or inaccurate.
Question 3 of 5
A 72-year-old client is admitted to the hospital with a diagnosis of acute exacerbation of diverticulitis. The healthcare practitioner prescribes the IV antibiotic ceftazidime. After confirming the client's allergies, which intervention should the nurse implement NEXT before giving the drug?
Correct Answer: B
Rationale: Ensuring IV patency is the next step to guarantee safe antibiotic delivery. Vital signs, white blood count, and stool specimens are important but not immediate priorities.
Question 4 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 5 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.
