Question

Doctor's order: Infuse 50mg of Amphotericin B in 250ml NS over 4 hr 15 min; Drop factor : 12gtt/ml. What flow rate ( ml/hr) will you set on the IV infusion pump? ____ ml/hr

Answer 1

59 ml/hr

Explanation:

Amount of solution = 250 ml

Flow rate = 250 ÷ 4.25 hrs = 58.82352941176 ml/hr

since answer is required in ml/hr and not gtt/hr,

Therefore answer = 59 ml/hr to the nearest flow rate.

Answer 2

59 ml/hr.

Explanation:

Given:

time, t = 4hr 15min

= 4.25 h.

Volume = 250 ml

Infusion time = total volume/time

= 250/4.25

= 58.8 ml/hr.
