A nurse is caring for client who has sepsis and a prescription for vancomycin 1 g in 250 mL dextrose 5% (D,W) over 2 hr by IV intermittent bolus. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["125"]
To calculate the IV pump rate:
- Total volume of dextrose solution: 250 mL
- Time for infusion: 2 hours
- The pump rate is calculated as total volume divided by time: 250/2
- This results in a pump rate of 125 mL/hr
Therefore, the nurse should set the IV pump to deliver 125 mL/hr.

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.
