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.

Explanation
The nurse should administer 10 mL of amoxicillin oral suspension 125 mg/5 mL to give the client a total dose of 250 mg.
Choice A is not the best answer because administering 2 mL of amoxicillin oral suspension 125 mg/5 mL would only give the client a total dose of 50 mg, which is not enough.
Choice B is not the best answer because administering 5 mL of amoxicillin oral suspension 125 mg/5 mL would only give the client a total dose of 125 mg, which is not enough.
Choice C is not the best answer because administering 8 mL of amoxicillin oral suspension 125 mg/5 mL would give the client a total dose of 200 mg, which is not enough.

Sharing passwords can compromise the security and confidentiality of patient information.
For the second question you asked, the correct answer is choice A.
“I’ll use my electric razor for shaving.” This statement indicates that the client understands that warfarin (coumadin) can increase the risk of bleeding and that using an electric razor can help reduce the risk of cuts and bleeding while shaving.
Choice B is not the best answer because taking aspirin while on warfarin (coumadin) can increase the risk of bleeding.
