A nurse is preparing to administer azithromycin to a client who is at 16 weeks of gestation and has a positive chlamydia culture. The prescription states "Administer azithromycin 1 g orally now." Available are 250 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
C
Rationale
The correct answer is C: 4 tablets. Azithromycin 1g is equivalent to 1000mg. Since each tablet is 250mg, the nurse should administer 1000mg/250mg = 4 tablets. This dosage is appropriate for treating chlamydia infection. Choice A is incorrect because 8 tablets would be equivalent to 2000mg, which is double the prescribed dosage. Choice B is incorrect as 6 tablets would be 1500mg, which is higher than the prescribed dosage. Choice D is incorrect as 2 tablets would only be 500mg, which is lower than the prescribed dosage.
