Question

17. A patient presents to ER for symptoms of croup. The doctor order Dexamethasone 0.6 mg/kg/dose. Patient weight: 14.2kg. How many mg will be ordered for this patient?

18. 1000 mL of D5 ½ NS is ordered to infuse over 8 hours. An infusion pump is used. At what rate should the nurse set the pump? How many mL/hr?
19. The physican ordered 1500 mL of D5 NS to run over 24 hours. The drop rate factor is 10 gtt/mL.
How many mL/hr should infuse?

Answer 1

17. The ordered dosage is 0.6 mg/kg/dose. Therefore, for a patient weighing 14.2 kg, the dosage will be:

0.6 mg/kg x 14.2 kg = 8.52 mg/dose

So, 8.52 mg of dexamethasone will be ordered for this patient.

18. The ordered amount is 1000 ml to be infused over 8 hours. The nurse should set the pump to:

1000 ml ÷ 8 hours = 125 ml/hr

Therefore, the rate on the pump should be set at 125 ml/hr.

19. The ordered amount is 1500 ml to be infused over 24 hours. To calculate the infusion rate, we need to convert 24 hours to minutes (1440 minutes).

The calculation for the infusion rate will be:

1500 ml ÷ 1440 minutes = 1.04 ml/min

Next, we need to convert the ml/min to ml/hr. There are 60 minutes in 1 hour, so we can multiply the ml/min by 60.

1.04 ml/min x 60 = 62.4 ml/hr

Therefore, the infusion rate should be set at 62.4 ml/hr.

Since the drop rate factor is given as 10 gtt/ml, the drip rate will be:

62.4 ml/hr x 10 gtt/ml = 624 gtt/hr

So, the infusion rate for this patient is 62.4 ml/hr, and the drip rate is 624 gtt/hr.
