Question

A child has been prescribed 240 mL of fluid to administered by micro drip set over 6 hours, the nurse will regulate IV at
1. 160 drops/min
2. 120 drops/min
3. 40 drops/min
4. 60 drops/min 

Answer 1

Correct Answer - Option 3 : 40 drops/min

Explanation:

Drops per minute (gtss/min)

Common drop factors:

Macro	10 gtt/1 mL
	15 gtt/1 mL
	20 gtt/1 mL
Micro	60 gtt/1 mL

 

\(gtss/\min = \frac{{\left( {Total\;Volume} \right)\left( {Drop\;Factor} \right)}}{{Time\;in\;minutes}}\)

Given: 240 ml, 6 hours, Micro drip = 60 gtt/1 mL

\(gtss/\min = \frac{{\left( {240} \right)\left( {60} \right)}}{{6\times 60}} =40 \,drops/min\)
