The nurse is planning care for a client with type 1 diabetes mellitus. When planning administration for rapid-acting insulin Lispro, the nurse knows to administer it during which timeframe based on the onset of action?

Lispro lasts 24 hours and does not have to be timed with meals.

60 minutes before meals.

15-30 minutes before meals.

2-6 hours before meals.

Answer and Explanation

The Correct Answer is C

A. This statement is incorrect. Lispro is a rapid-acting insulin, and its duration of action is much shorter than 24 hours. It is typically effective for about 3-5 hours.
B. Administering Lispro 60 minutes before meals would be too early, as it peaks in about 1-2 hours after injection and works best when given closer to meal times.
C. Lispro should be administered 15-30 minutes before meals to match the onset of action, which begins within 15 minutes of injection. This timing allows the insulin to be active when blood glucose rises after eating.
D. Lispro does not require administration 2-6 hours before meals, as this would not align with its rapid onset of action.

Correct Answer is ["B","D","E"]

Explanation

A. Intact motor function is not a sign of compartment syndrome. Motor deficits, rather than intact function, would raise concern for this condition.
B. A capillary refill time of 5 seconds is prolonged and indicates impaired circulation, which is a sign of compartment syndrome.
C. A bounding pulse is not consistent with compartment syndrome. Pulses may initially remain normal but can diminish as the condition progresses.
D. Pallor to the lower extremity suggests compromised blood flow, which is a hallmark of compartment syndrome.
E. Numbness and tingling (paresthesia) indicate nerve compression, a common symptom of compartment syndrome.

A. The client who has heart failure and has crackles upon lung auscultation. B. The client who has renal failure and has pitting edema. C. The client who has been NPO for 4 hours in preparation for endoscopy. D. The client who is having an exacerbation of Crohn's disease with diarrhea.

Correct Answer is D

Explanation

A. A client with heart failure and crackles in the lungs is more likely to have fluid volume excess rather than deficit.
B. A client with renal failure and pitting edema is typically at risk for fluid retention and overload, not deficit.
C. Being NPO for 4 hours is unlikely to cause significant fluid volume deficit, as this is a short period without oral intake.
D. A client with Crohn's disease experiencing diarrhea is losing significant fluids and electrolytes, placing them at high risk for fluid volume deficit. Diarrhea is a common cause of dehydration and requires close monitoring.
