A healthcare provider orders atropine sulfate 400 mcg IM as a preoperative medication. The medication is provided as 0.1 mg/mL. How many mL should the nurse administer?
2 mL
3 mL
4 mL
5 mL
The Correct Answer is C
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 D
Explanation
The toddler is ordered to receive 25 mg/kg of Principen IV over 30 minutes. The toddler weighs 22 lb, which is equivalent to 10 kg. To calculate the total amount of Principen the toddler should receive, multiply the weight by the dosage:
10 kg x 25 mg/kg = 250 mg
The Principen dose arrives from the pharmacy prepared in 50 mL of IV solution, which means there is 250 mg of Principen in 50 mL of solution. To calculate how many milliliters per hour the nurse should administer, we can use the following formula:
50 mL / 0.5 hour = X mL per hour X = 100 mL per hour
Therefore, the nurse should administer 100 mL of Principen per hour to the toddler.
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.
