The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["45"]

To find the answer, we can use the following formula:

(microdrops/minute) = (mL/hour) x (microdrops/mL) / 60

Substituting the given values, we get:

(microdrops/minute) = (45) x (60) / 60

Simplifying, we get:

(microdrops/minute) = 45

Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.

Correct Answer is ["1200"]

Explanation

To find the answer, we can use the following formula:

(units of heparin) = (mL/hour) x (hours) x (units per mL)

Substituting the given values, we get:

(units of heparin) = (25) x (12) x (20,000 / 500)

Simplifying, we get:

(units of heparin) = (25) x (12) x (40)

(units of heparin) = 1200

Therefore, the client should receive 1200 units of heparin in 12 hours.

Correct Answer is ["20.7 mL\/hour"]

Explanation

To find the answer, we can use the following steps:

- Calculate the dosage of dopamine in mcg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60

- Calculate the concentration of dopamine in the solution by dividing the amount of dopamine in mg by the volume of solution in mL and multiplying by 1000

- Divide the dosage of dopamine by the concentration of dopamine in the solution to get the volume to be delivered in mL/hour

- Round the result to the nearest tenth

Using these steps, we get:

- (dosage of dopamine in mcg/hour) = (91) x (3) x (60) = 16,380 mcg/hour

- (concentration of dopamine in solution) = (400 / 250) x (1000) = 1600 mcg/mL

- (volume to be delivered in mL/hour) = (16,380) / (1600) = 10.2375 mL/hour

- (rounded volume to be delivered in mL/hour) = 10.2 mL/hour

Therefore, the nurse should program the infusion pump to deliver 10.2 mL/hour of dopamine in 5% dextrose injection to the patient.
