A nurse is preparing to administer 0.9% sodium chloride 250 mL IV to infuse over 4 hr to a school-age child. The nurse should ensure the IV pump is set to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["63"]
Step-by-step calculation:
IV rate= Total volume/Time (hours)
250/4 =62.5 mL/hr
Round the answer off: 63L/hr

Correct Answer is ["1.1"]
Explanation
Step-by-Step Solution:
Convert the adolescent's weight from pounds to kilograms.
1 pound is = 0.453592 kilograms.
79 pounds = 79 x 0.453592 = 35.793592 kilograms.
Calculate the total dose of dimercaprol.
The prescribed dose is 3 mg/kg.
The adolescent weighs 35.793592 kg.
The total dose = 3 mg/kg x 35.793592 kg = 107.380776 mg.
Calculate the volume of dimercaprol injection to administer.
The available dimercaprol injection is 100 mg/mL.
To find the volume, we can set up a proportion:
100 mg / 1 mL = 107.380776 mg / x mL
Cross-multiplying:
100x = 107.380776
Solving for x:
x = 107.380776 / 100 = 1.07380776 mL
Round the answer to the nearest tenth: 1.1 mL.
Correct Answer is ["500"]
Explanation
Step 1: Identify the given information:
Volume of the solution: 125 mL
Infusion time: 15 minutes
Step 2: Convert the infusion time to hours:
15 minutes = 15/60 hours = 0.25 hours
Step 3: Calculate the infusion rate in mL/hr:
Infusion rate = Volume / Time
Step 4: Substitute the values:
Infusion rate = 125 mL / 0.25 hr
Step 5: Calculate the result:
Infusion rate = 500 mL/hr
