The healthcare provider prescribes regular insulin 10 units/hr IV. The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline. How many mL/hr should the nurse program the infusion pump? (Enter numerical value only.)
Correct Answer: 10 mL/hr

Imaging Studies
A 19-year-old female client presents to the emergency department reporting tightness in her chest and difficulty breathing. The client's friend, who accompanied the client to the emergency department, reports she was at a park playing soccer with a group of college friends when the symptoms started. The park is close to a residential area where a fire was burning and there was a moderate breeze in the air. The client reported itching eyes and coughing. Approximately 15 minutes into the game, the client stopped running and held her hand on her chest, saying it felt tight. The client had difficulty catching her breath.

Question 3 of 5
The nurse is conducting an admission assessment of an infant with heart failure who is scheduled for repair of restenosis of coarctation of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Which pathophysiologic mechanism supports these findings?
Correct Answer: A
Rationale: Coarctation of the aorta narrows the aortic lumen, reducing blood flow to the lower extremities, causing higher blood pressure in the arms and weaker pulses in the legs.
Question 4 of 5
A client with chronic kidney disease on peritoneal dialysis exhibits redness, tenderness, and drainage around the catheter site on the abdominal wall. While planning care, the nurse is most concerned about preventing which complication related to these findings?
Correct Answer: B
Rationale: Redness, tenderness, and drainage suggest an exit site infection, a common peritoneal dialysis complication, which must be prevented to avoid progression to peritonitis.
Question 5 of 5
A client who had a biliopancreatic diversion procedure (BDP) 3 months ago is admitted with severe dehydration. Which assessment finding warrants immediate intervention by the nurse?
Correct Answer: B
Rationale: Occult positive emesis indicates vomiting, which can exacerbate dehydration through significant fluid loss, requiring immediate intervention in a post-BDP client already dehydrated.
