Question 1:
A nurse is caring for a newborn who weighs 3,500 g. The nurse should record
the newborn's weight as how many kg? (Round the answer to the nearest tenth.
Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 3.5
To convert the weight of the newborn from grams to kilograms, one needs to divide
the number of grams by 1,000 since there are 1,000 grams in a kilogram. Therefore, a
newborn who weighs 3,500 grams would be recorded as weighing 3.5 kilograms.

Question 2:
A nurse is preparing to administer dextrose 5% in 0.9% sodium chloride 250 mL
IV to infuse over 4 hr to a pregnant client who has a blood glucose level of 65
mg/dL. The nurse should set the IV pump 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.).
Explanation
Correct Answer: 63
To calculate the infusion rate for the IV pump, the total volume of the IV fluid (250 mL)
should be divided by the time over which the infusion is to take place (4 hours). This
calculation results in an infusion rate of 62.5 mL/hr. Since the infusion pump cannot be
set to a decimal, the rate is rounded to the nearest whole number, which is 63 mL/hr.

Question 3:
A nurse is preparing to administer acetaminophen 0.65 g PO to a client for a
report of postpartum pain. Available is acetaminophen 325 mg tablets. How
many tablets should the nurse plan to administer? (Round the answer to the
nearest whole number. Use a leading zero if it applies. Do not use a trailing
zero.)
2/24
, Explanation
Correct Answer: 2
To convert grams to milligrams, the value in grams is multiplied by 1,000. Therefore,
0.65 grams of acetaminophen is equivalent to 650 milligrams. If one tablet contains
325 milligrams, the number of tablets needed would be 650 mg divided by 325 mg per
tablet, which equals 2.

Question 4:
A nurse is reviewing a new prescription with the parent of a newborn who is to
receive ferrous sulfate 15 mg PO daily. Available is ferrous sulfate drops 75
mg/0.6 mL. How many mL should the parent administer to the newborn each
day? (Round the answer to the nearest hundredth. Use a leading zero if it
applies. Do not use a trailing zero.)
Explanation
Correct Answer: 0.12
To determine the correct dosage of ferrous sulfate drops for the newborn, one must
use the formula: (Desired Dose / Concentration) = Volume to Administer. In this case,
the desired dose is 15 mg, and the concentration available is 75 mg per 0.6 mL.
Therefore, the calculation would be (15 mg / 75 mg) * 0.6 mL, which equals 0.12 mL.
