An infant with respiratory depression requires resuscitation with Narcan. The infant weighs 5 pounds, 13 ounces, and the order is for 0.1 mg/kg. Narcan is available as 0.4 mg/mL drug. What is the correct mL to administer?

the correct mL to administer is 0.66mL

Explanation:

1 pounds = 0.454kg

1ounces = 0.0283kg

1000mL = 1kg

1ml = 0.001kg

therefore,

5 pounds = 2.27kg

13 ounces = 0.369kg

total weight of the infants = 2.27 + 0.369 = 2.639kg

the order is for 0.1 mg/kg i. e for every 1kg = 0.1mg is used

therefore for 2.639kg = 0.2639mg

Narcan is available as 0.4 mg/mL drug.

1ml = 0.001kg

? = 2.639kg

? = 2639mL

0.4mg for 1ml

0.2639mg = 0.66mL

the correct mL to administer is 0.66mL
