The healthcare provider prescribes epinephrine 0.01 mg/kg intramuscularly for a child with asthma who weighs 55 pounds. The available medication is labeled 1 mg/mL. Based on the child's weight, how many mL should the nurse administer?
(Enter numerical value only. If rounding is required, round to the nearest hundredth.)
Answer and Explanation

The Correct Answer is ["0.25"]

Let’s calculate step by step:

 

Convert weight to kilograms

55 lb÷2.2=25 kg

Determine dose in mg

0.01 mg/kg×25 kg=0.25 mg

Available concentration

1 mg/mL

Calculate volume to administer

0.25 mg1 mg/mL=0.25 mL

Final Answer: 0.25

Correct Answer is ["120"]

Explanation

To calculate the infusion rate in mL/hour, we can use the following formula:

Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:

200 mg/40 mL = 5 mg/mL

We can calculate the infusion rate as follows:

2 mg/minute x 60 / 5 mg/mL = 24 mL/hour

However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:

200 mL / (120 minutes) = 100 mL/hour

So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:

2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:

X = (2 x 60 x 1) / 5 = 24 mL/hour

So we should program the infusion pump to deliver 6 mL/hour.

Correct Answer is ["8"]

Explanation

The total daily dose is 80 mg (20 mg x 4). Since the medication is available in 10 mg tablets, we can calculate the number of tablets required as follows:

80 mg / 10 mg per tablet = 8 tablets
