Let's solve this step-by-step.
1. Understand the given data:
- The physician orders Cefazolin sodium 1 gram to be diluted in 50 mL of normal saline (NS).
- The entire 50 mL solution needs to be infused over a period of 60 minutes.
2. Determine the volume infused per minute:
To find out how much Cefazolin solution is administered per minute, we divide the total volume by the total infusion time:
[tex]\[
\text{Volume per minute} = \frac{50 \text{ mL}}{60 \text{ minutes}} = 0.8333 \text{ mL per minute}
\][/tex]
3. Convert the infusion rate per minute to per hour:
Since there are 60 minutes in an hour, we multiply the volume per minute by 60 to find the volume infused in an hour:
[tex]\[
\text{Volume per hour} = 0.8333 \text{ mL/min} \times 60 \text{ minutes} = 50 \text{ mL/hour}
\][/tex]
Therefore, the nurse would administer 50 mL of the Cefazolin solution in an hour.
