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.

A. Apical pulse rate is different than the radial pulse rate B. Drop in systolic BP by 20 mm Hg when changing positions C. Increase in heart rate by 20% when moving from sitting to standing D. Decrease in systolic pressure by more than 10 mm Hg during inspiration

Correct Answer is D

Explanation

A. A difference between the apical pulse rate and the radial pulse rate is more indicative of a pulse deficit, which is not specific to constrictive pericarditis.
B. A drop in systolic blood pressure by 20 mm Hg when changing positions describes orthostatic hypotension, not paradoxical blood pressure.
C. An increase in heart rate when moving from sitting to standing reflects orthostatic changes, not paradoxical blood pressure.
D. Paradoxical blood pressure refers to a decrease in systolic blood pressure of more than 10 mm Hg during inspiration, which can occur in constrictive pericarditis due to impaired filling of the heart during diastole.
