A physician gives the following order: "Infuse 0.9% sodium chloride solution, 2.5 L over 15 hours." What is the mL/hr flow rate for continuous infusion?
41.67 mL/hr
166.67 mL/hr
250 mL/hr
1000 mL/hr
The Correct Answer is B
To calculate the flow rate in mL/hr for a continuous infusion, we need to divide the total volume to be infused by the total time of infusion, and then convert the units as necessary.
In this case, the total volume is 2.5 L, which is equivalent to 2500 mL (1 L = 1000 mL), and the total time is 15 hours.
Flow rate = Total volume to be infused / Total time of infusion Flow rate = 2500 mL / 15 hours
Flow rate = 166.67 mL/hr
Therefore, the flow rate for continuous infusion of 0.9% sodium chloride solution in this case is 166.67 mL/hr.

Correct Answer is B
Explanation
If one dose of medication is 25 mg and each vial contains 50 mg of medication, then each vial contains two doses..
To calculate the number of vials required for 5 days of treatment, we first need to calculate the total number of doses required. Since the client requires two injections per day, the total number of doses required for 5 days would be:.
Total number of doses = 2 doses/day x 5 days. Total number of doses = 10 doses.
Since each vial contains two doses, we need a total of 10/2 = 5 vials for 5 days of treatment..
Therefore, the nurse would need 5 vials of the medication for 5 days of treatment for the client.
Correct Answer is C
Explanation
The patient is ordered to receive 5 mg of Lopressor over 60 seconds, which is equivalent to 1 minute. The concentration of Lopressor is 1 mg/1 mL, which means there is 1 mg of Lopressor in 1 mL of solution. To calculate how many milliliters per minute the nurse should administer, we can use the following formula:
5 mg / 1 mg per 1 mL = X mL X = 5 mL per minute.
