D. Sinus bradycardia shows a slow heart rate and is not associated with an irregular heart rate or significant pulse deficit.
Correct Answer is ["8"]
Explanation
Given:
- IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline.
- The prescribed rate is 8 units/hr.
First, we find out how many units are present in 1 mL of the IV solution:
100 units / 100 mL = 1 unit / 1 mL
Now, since the prescribed rate is 8 units/hr, we need to infuse 8 mL/hr of the IV solution to deliver 8 units of insulin per hour.
So, the nurse should program the infusion pump to deliver 8 mL/hr.
