2. 600ml NSS over 12hrs. What do you set the pump at?.
3. 300ml D5W over 2hrs with 20mEq K, 15gtts/ml What is the flow rate by gravity?
4. 500ml 1/2NSS at 25ml/hr How long will this run over?
5. 120ml to run over 1/2hr with macrodrip 10gtts/ml What is the flow rate by gravity?
2) Rate = volume÷ time.
Rate. = 600 ml ÷ 12hr.
= 50ml/hr.
3) flow rate by gravity = volume (min) ÷ time (hr) × drop factor.
Flow rate = (300 × 15) ÷ 120
= 4500÷120
= 37.5.
Flow rate by gravity is 37.5 gtt/min.
4) Rate = volume ÷ time
time = volume ÷ rate.
= 500 ml ÷ 25ml/ hr.
= 20 hr.
5) flow rate by gravity = volume × drop factor ÷ time.
= 120× 10 ÷ 30
= 4 ×10 .
= 40.
Flow rate is 40 gtt/min.
