Correct Answer is C
Explanation
The ordered dose is 400 mcg, which is equal to 0.4 mg..
The medication is provided as 0.1 mg/mL, so to administer 0.4 mg, the nurse needs to give:.
0.4 mg ÷ 0.1 mg/mL = 4 mL.
Therefore, the nurse should administer 4 mL of atropine sulfate.
Correct Answer is A
Explanation
The infusion was started at 06:57 and completed at 15:45, which is a total time of: 15 hours and 45 minutes - 6 hours and 57 minutes = 8 hours and 48 minutes
To calculate the flow rate, we need to know the total amount of fluid infused and divide it by the total time of infusion:
1 L = 1000 mL
Total time of infusion = 8 hours and 48 minutes = 528 minutes Flow rate = Total amount of fluid infused / Total time of infusion Flow rate = 1000 mL / 528 minutes
Flow rate = 1.89394 mL/min
To convert mL/min to mL/hr, we multiply by 60:
Flow rate = 1.89394 mL/min x 60 min/hr Flow rate = 113.6364 mL/hr
Therefore, the flow rate of infusion in this situation is approximately 114 mL/hr, which corresponds to option A.
