Amoxicillin 500 mg is ordered for a patient with a sinus infection. Amoxicillin oral suspension 200 mg per 5 mL is available.
How many mL should the nurse administer?

A.

5.5 mL

B.

10.5 mL

C.

12.5 mL

D.

15.5 mL

Answer and Explanation

The Correct Answer is C

The nurse should administer 12.5 mL of amoxicillin oral suspension.

This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:

200 mg / 5 mL = 500 mg / x mL

Cross-multiplying and solving for x gives:

x = 12.5 mL

Therefore, the nurse should administer 12.5 mL of amoxicillin oral suspension to deliver 500 mg of the medication to the patient.

Correct Answer is B

Explanation

This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:

centimeters = inches × 2.54

For example, if a patient's height is 60 inches, then the height in centimeters is:

centimeters = 60 × 2.54
centimeters = 152.4

Therefore, the patient's height is 152.4 centimeters.

Correct Answer is A

Explanation

To find the rate in mL/hr, you need to calculate the following:

- The concentration of nitroglycerin in the IV solution in mcg/mL
- The infusion rate in mL/hr using the formula: Infusion rate (mL/h) = (Dose (mcg/min) x 60 min/h) / Concentration (mcg/mL)

First, convert the concentration of nitroglycerin from mg to mcg by multiplying by 1000:

125 mg x 1000 = 125,000 mcg

Then, divide the amount of nitroglycerin by the volume of the IV solution to get the concentration in mcg/mL:

125,000 mcg / 500 mL = 250 mcg/mL

Next, plug in the values into the formula for infusion rate:

Infusion rate (mL/h) = (42 mcg/min x 60 min/h) / 250 mcg/mL

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 10.08 mL/h

Therefore, the nurse should program the IV pump to deliver **10.1 mL/h** to infuse nitroglycerin at 42 mcg/minute.
