The nurse calculates that 8 ml of cefazolin is to be drawn from a vial after reconstitution. The instructions state that the medication is to be further diluted in 50 mls of NSS for IV administration and to run over 30 minutes. At what rate will the nurse set to infusion pump to deliver the medication?
The Correct Answer is ["116"]
To calculate the infusion rate, we'll follow these steps:
Determine the total volume to be administered:
8 mL (drawn from the vial) + 50 mL (dilution with NSS) = 58 mL
Calculate the infusion rate:
58 mL ÷ 30 minutes = 1.93 mL/minute
Convert mL/minute to mL/hour:
1.93 mL/minute × 60 minutes/hour = 116 mL/hour

Correct Answer is A
Explanation
A. Avoid needle sticks or other invasive procedures as much as possible: This is the most appropriate action for a client with thrombocytopenia. Since thrombocytopenia involves a low platelet count, the risk of bleeding is increased, and minimizing invasive procedures helps prevent complications.
B. Hold all stool softeners and laxatives until otherwise: This statement is not appropriate. Clients with thrombocytopenia should avoid straining during bowel movements, which can be facilitated by the use of stool softeners or laxatives if necessary.
C. Encourage vigorous tooth brushing with a soft bristle toothbrush: This is not advisable. While using a soft-bristled toothbrush is recommended, vigorous brushing could cause gum bleeding. Gentle oral hygiene practices should be emphasized instead.
D. Obtain a core temperature every 8 hours: While monitoring temperature is important, it is not specific to thrombocytopenia management. Other vital signs may be monitored more frequently, but this action does not directly address the primary concern of bleeding risk.
Correct Answer is ["480"]
Explanation
To calculate the infusion rate, you need to determine the total volume to be infused and the time over which it will be infused.
Total volume to be infused = 200 mL
Time for infusion = 25 minutes
Infusion rate = Total volume / Time Infusion rate = 200 mL / 25 minutes = 8 mL/min
To convert this to mL/hour (since infusion pumps are typically set in mL/hour): Infusion rate = 8 mL/min × 60 minutes/hour = 480 mL/hour
