Correct Answer is ["2"]

Explanation

Given:

Ordered dose of Fentanyl: 100 mcg

Concentration of Fentanyl: 0.05 mg/mL

Step 1: Convert mcg to mg:

Ordered dose (mg) = Ordered dose (mcg) / 1000 mcg/mg

Ordered dose (mg) = 100 mcg / 1000 mcg/mg

Ordered dose (mg) = 0.1 mg

Step 2: Set up the proportion:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Step 3: Substitute the values:

0.1 mg / Volume = 0.05 mg/mL

Step 4: Solve for the unknown volume:

Volume = 0.1 mg / (0.05 mg/mL)

Volume = 0.1 mg x (1 mL / 0.05 mg)

Volume = 2 mL

Correct Answer is ["1"]

Explanation

Given:

Ordered dose of loratadine: 5 mg

Concentration of loratadine suspension: 5 mg per 5 mL

1 teaspoon = 5 mL

Step 1: Determine the volume of loratadine suspension to be administered:

Since the ordered dose and the concentration are the same (5 mg), the volume to be administered is 5 mL.

Step 2: Convert mL to teaspoons:

1 teaspoon = 5 mL

Volume in teaspoons = 5 mL / 5 mL/teaspoon

Volume in teaspoons = 1 teaspoon
