A nurse is to administer a 500ml bolus of normal saline to a patient over 1 hour?
The Correct Answer is ["500"]
To calculate the infusion rate in ml/hr for a 500 ml bolus to be administered over 1 hour, you can simply set the pump to deliver the entire volume in the specified time:
500 ml / 1 hour = 500 ml/hr
So, the pump should be set at 500 ml/hr to administer the 500 ml bolus over 1 hour.

Correct Answer is B
Explanation
A. There is no need for the client to lie flat for an extended period after a DEXA scan. The procedure is non-invasive and does not require immobilization.
B. Emptying the bladder before the test is essential to ensure a clear and accurate scan of the pelvis and lower spine. A full bladder might obstruct the view and affect the accuracy of the results.
C. DEXA scans do not typically require the use of IV dye. It is a simple X-ray procedure that measures bone density, and no contrast material is usually needed.
D. Fasting is not necessary for a DEXA scan. The procedure does not involve ingesting or injecting any substances that require fasting.
Correct Answer is ["250"]
Explanation
To calculate the infusion rate, you first need to determine the total volume to be infused and the total time over which the infusion will occur.
Three 1L bags need to be infused over 12 hours.
Total volume = 3 bags * 1000 mL/bag = 3000 mL
Total time = 12 hours
Now, to find the rate in milliliters per hour (mL/h), divide the total volume by the total time:
Infusion rate = Total volume / Total time
Infusion rate = 3000 mL / 12 hours = 250 mL/h
