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.

Correct Answer is A

Heparin is an anticoagulant that decreases the clotting ability of the blood 1.
Using a soft-bristled toothbrush can help prevent bleeding of the gums while brushing teeth.
Choice B is incorrect because heparin should not be injected deep into the thigh muscle.
Instead, it should be given subcutaneously (under the skin) 2.
Choice C is incorrect because black and tarry stools are not an expected side effect of heparin.
Choice D is incorrect because easy bruising does not indicate that the medication is effective.
Instead, easy bruising may be a side effect of heparin and should be reported to the healthcare provider 1.

Explanation
Protamine sulfate is a medication that can be used to reverse the anticoagulant effects of heparin1.
It is a polycationic protein drug obtained from the sperm of fish and is used to reverse the anticoagulant effect of unfractionated heparin (UFH)2.
Choice B, Deferoxamine, is not the correct answer because it is a medication used to treat iron overload, not to reverse heparin’s effects.
Choice C, Sodium polystyrene sulfonate, is not the correct answer because it is a medication used to treat high levels of potassium in the blood, not to reverse heparin’s effects.
