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.
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.

Choice A is not correct because a 1-inch needle may be too long for subcutaneous injection.
A shorter needle, such as a 3/8 to 5/8 inch needle, is typically used for subcutaneous injections.

A smaller gauge needle, such as a 25- or 27-gauge needle, is typically used for subcutaneous injections.
