ATI n200 Med Surg Exam 6 Questions
Extract:
Question 1 of 5
After having bariatric surgery, a client being discharged tells the nurse, 'I prefer to be independent. I'm not interested in joining a support group.' Which response by the nurse is best?
Correct Answer: A
Rationale: Highlighting the practical benefits of support groups encourages adherence to lifestyle changes without pressuring the client, respecting their autonomy.
Question 2 of 5
The physician ordered cephalexin 4 mg/kg PO Q6 hours. The medication is available at 250 mg/5 mL. The client weighs 245 pounds. What is the correct dose to be administered every 6 hours? (Round the answer to the nearest whole number. Do not use a trailing zero.)
Correct Answer: 9
Rationale: Client weight: 245 lbs ÷ 2.2 = 111.36 kg. Dose: 4 mg/kg × 111.36 = 445.44 mg. Available: 250 mg/5 mL, so 445.44 ÷ (250/5) = 8.91 mL, rounded to 9 mL.
Question 3 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 4 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 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.
