A nurse is preparing to administer cefixime to a patient. The dose is 200 mg PO.

Available is cefixime oral suspension 100 mg/mL.

How many milliliters should the nurse administer?

Use a leading zero if it applies. Do not use a trailing zero.

1.9 mL.

2 mL.

2.1 mL.

2.2 mL.

Answer and Explanation

The Correct Answer is B

To calculate the volume of cefixime oral suspension that the nurse should administer, you need to divide the prescribed dose (200 mg) by the concentration of the suspension (100 mg/mL).
This gives you 200 mg ÷ 100 mg/mL = 2 mL.
Therefore, the nurse should administer 2 mL of cefixime oral suspension.
Choice A is incorrect because 1.9 mL would provide a dose of 190 mg.
Choice C is incorrect because 2.1 mL would provide a dose of 210 mg.
Choice D is incorrect because 2.2 mL would provide a dose of 220 mg.

Correct Answer is B

Explanation

Step 1: Calculate the total infusion time in minutes.

24 hours × (60 minutes/hour) = 1440 minutes.

Step 2: Calculate the infusion rate in mL/min.

1200 mL ÷ 1440 minutes = 0.833 mL/min.

Step 3: Calculate the drop rate in gtt/min.

0.833 mL/min × 15 gtt/mL = 12.495 gtt/min.

Step 4: Round to the nearest whole number.

12.495 ≈ 13 gtt/min.

Answer: 13 gtt/min.

A. 2 tablets. B. 2.5 tablets. C. 2.6 tablets. D. 3 tablets.

Correct Answer is B

Explanation

The nurse should administer 2.5 tablets.
To determine the number of tablets needed to administer a dose of 5 mg using 2 mg tablets, you can divide the desired dose (5 mg) by the available tablet strength (2 mg/tablet): 5 mg ÷ 2 mg/tablet = 2.5 tablets.
Choice A is incorrect because administering 2 tablets would only provide a dose of 4 mg (2 tablets x 2 mg/tablet = 4 mg).
Choice C is incorrect because administering 2.6 tablets would provide a dose of 5.2 mg (2.6 tablets x 2 mg/tablet = 5.2 mg).
Choice D is incorrect because administering 3 tablets would provide a dose of 6 mg (3 tablets x 2 mg/tablet = 6 mg).
