If 150 mg of a drug is ordered IVP stat over 2 minutes, and the concentration of the drug is 75 mg/mL, find the total number of milliliters, and indicate how many milliliters you will administer per minute.

A.

1 mL total, 1 mL/min.

B.

2mL total, 1 mL/min.

C.

4 mL total, 2 mL/min.

D.

10 mL total, 5 mL/minute

Respuesta :

Answer:

(B) 2mL total, 1 mL/min.

Step-by-step explanation:

Given:

Amount of drug ordered = 150 g

Time = 2 minutes

Concentration of the drug = 75 mg/mL

now,

Concentration = Amount of drug / volume  .........(1)

thus,

Volume = Amount of drug / Concentration

or

Volume = 150 g / (75 g/mL)

or

Volume = 2 mL

also,

milliliters to administer per minute = Volume / time

or

milliliters to administer per minute = 2 mL / 2 min = 1 mL/min

Hence, the correct answer is option (B)
