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 A
Explanation
To determine the mL per dose of heparin, we can use the following formula:
mL per dose = (total units needed) / (concentration of heparin in units/mL). Substituting the values given in the
Question :.
mL per dose = 10,000 units / 20,000 units/mL = 0.5 mL per dose.
Therefore, the client should receive 0.5 mL per dose of heparin from the vial containing a concentration of 20,000 units/mL.
Correct Answer is C
Explanation
The number of tablets and their weight only provide information about the total amount of medication in the vial (100 tablets x 333 mg = 33,300 mg or 33.3 g).
