Correct Answer is ["22.6"]

Explanation

= 22.56 mL The nurse should administer 22.6 mL (rounded to the nearest tenth).

A. You should wear glasses instead of contacts while taking this medication. B. A yellow tint to the skin is an expected reaction to the medication. C. Lifelong treatment with this medication is necessary. D. The medication causes amenorrhea if taken along with an oral contraceptive.

Correct Answer is A

Explanation

Choice A rationale
Rifampin can cause discoloration of body fluids, including tears, which can stain contact lenses. Therefore, it is recommended to wear glasses instead of contacts while taking this medication.
Choice B rationale
A yellow tint to the skin is not an expected reaction to rifampin. This could indicate jaundice, a sign of liver dysfunction, which requires immediate medical attention.
Choice C rationale

Lifelong treatment with rifampin is not necessary. The typical duration of treatment for active tuberculosis is 6 to 9 months.
Choice D rationale
Rifampin does not cause amenorrhea when taken with oral contraceptives. However, it can reduce the effectiveness of oral contraceptives, so additional contraceptive methods should be used.
