Ati rn dosage calculation rn maternal newborn proctored assessment 3.2 ( 35 Questions)
Question 1 of 35 :
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 sulphate 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.)
Correct Answer: 0.12
Calculation:
Prescribed dose = 15 mg
Available concentration = 75 mg per 0.6 mL
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (15 mg / 75 mg) x 0.6 mL
= 0.2 x 0.6 mL
= 0.12 mL.
