10 mL

6 mL

5 ml

7 mL

Answer and Explanation

The Correct Answer is B

Given:

Ordered dose of amoxicillin: 300 mg

Concentration of amoxicillin oral solution: 250 mg/5 mL

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

300 mg / Volume = 250 mg/5 mL

Step 3: Solve for the unknown volume:

Volume = 300 mg / (250 mg/5 mL)

Volume = 300 mg x (5 mL / 250 mg)

Volume = 6 mL

Correct Answer is A

Explanation

1. Determine the total volume to be infused: 100 mL

2. Calculate the infusion time in minutes: 30 minutes

3. Calculate the drip rate (gtt/min):

Drip rate = (Total volume / Infusion time) x Drop factor

Drip rate = (100 mL / 30 minutes) x 15 gtt/mL

Drip rate = 50 gtt/min

Therefore, the correct answer is 50 gtt/min

A. 5 mL B. 20 mL C. 15 mL D. 10 mL

Correct Answer is D

Explanation

Given:

Ordered dose of diphenhydramine: 25 mg

Available diphenhydramine: 12.5 mg/5 mL

Step 1: Set up the proportion:

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

Step 2: Substitute the values:

25 mg / Volume = 12.5 mg/5 mL

Step 3: Solve for the unknown volume:

Volume = 25 mg / (12.5 mg/5 mL)

Volume = 25 mg x (5 mL / 12.5 mg)

Volume = 10 mL
