A nurse is preparing to administer amoxicillin 300 mg PO. The amount lable is amoxicillin oral solution 250 mg/5 mL. How many mL should the nurse administer? (Hound the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A.

10 mL

B.

6 mL

C.

5 ml

D.

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 D

Explanation

Ordered dose of 0.9% Sodium Chloride: 20 mL/kg

Child's weight: 55 lbs

Infusion time: 6 hours

Step 1: Convert child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 55 lbs x 0.453592 kg/lb = 24.94756 kg

Step 2: Calculate the total volume of 0.9% Sodium Chloride:

Total volume (mL) = Ordered dose (mL/kg) x Child's weight (kg)

Total volume (mL) = 20 mL/kg x 24.94756 kg

Total volume (mL) = 498.9512 mL

Step 3: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Infusion rate (mL/hr) = 498.9512 mL / 6 hr

Infusion rate (mL/hr) = 83.15853333 mL/hr

Step 4: Round to the nearest whole number:

Infusion rate (mL/hr) ≈ 83 mL/hr

Correct Answer is A

Explanation

Given:

Volume of fluid: 3,000 mL

Infusion time: 24 hours

Formula:

Flow rate (mL/hr) = Volume (mL) / Time (hr)

Step 1: Calculate the infusion rate in mL/hr:

Flow rate (mL/hr) = 3,000 mL / 24 hr

Flow rate (mL/hr) = 125 mL/hr
