Question

Going down the croup protocol, how much epinephrine should be given to a 10 kg patient that is 9 months old?

A) 0.1 mg (1 mL of 1:10,000) via nebulizer
B) 0.2 mg (2 mL of 1:10,000) via nebulizer
C) 0.3 mg (3 mL of 1:10,000) via nebulizer
D) 0.4 mg (4 mL of 1:10,000) via nebulizer

Answer 1

The correct answer is B) 0.2 mg (2 mL of 1:10,000) via nebulizer for a 10 kg patient that is 9 months old. The recommended dose for a 10 kg patient is 0.1 mg/kg, which in this case would be 1 mg. Since we are using a nebulizer, the recommended volume is typically halved, resulting in 2 mL.

Step-by-step explanation:

The correct answer is B) 0.2 mg (2 mL of 1:10,000) via nebulizer for a 10 kg patient that is 9 months old.

When managing croup, also known as laryngotracheobronchitis, epinephrine is often administered to alleviate the symptoms. The recommended dose for a 10 kg patient is 0.1 mg/kg, which in this case would be 1 mg.

Since the concentration of the epinephrine solution is 1:10,000, we need to calculate the volume of solution needed to deliver the required dose. The formula to calculate this is: (dose in mg / concentration in mg/mL) x 1 mL = volume in mL. So, applying this formula, we get: (1 mg / 0.1 mg/mL) x 1 mL = 10 mL. However, since we are using a nebulizer, the recommended volume is typically halved, resulting in 5 mL. Therefore, the correct answer is 0.2 mg (2 mL of 1:10,000) via nebulizer.
