Passage / Scenario
A child with suspected rheumatic fever, prescribed an antistreptolysin O (ASO) titer.A nurse is caring for a child who was admitted with suspected rheumatic fever. The provider prescribes an antistreptolysin O (ASO) titer. The parent asks the nurse the purpose of the test. Which of the following responses should the nurse give?
Correct answer
A
Rationale
The correct answer is A: This test will confirm if your child had a recent streptococcal infection. The ASO titer measures the level of antibodies in the blood that the body produces in response to a streptococcal infection. Elevated levels indicate recent infection. Choice B is incorrect as ASO titer does not directly indicate rheumatic fever. Choice C is incorrect as it measures antibodies, not immunity. Choice D is incorrect as ASO titer is not used to monitor aminoglycoside levels.
