Passage / Scenario
A nurse is caring for a child who was admitted with suspected rheumatic fever. The provider prescribes an anti-streptolysin O (ASO) titer.A nurse is caring for a child who was admitted with suspected rheumatic fever. The provider prescribes an anti-streptolysin O (ASO) titer. The parent asks the nurse the purpose of the test. Which of the following responses should the nurse make?
Correct answer
D
Rationale
The correct answer is D. The ASO titer test is used to confirm if the child had a recent streptococcal infection by measuring the level of antibodies produced by the body in response to the streptococcal bacteria. This is important in diagnosing rheumatic fever, as it is often preceded by a streptococcal infection.
Choice A is incorrect as the ASO titer does not measure therapeutic blood levels of aminoglycosides. Choice B is incorrect because the test does not directly diagnose rheumatic fever, but rather indicates a recent streptococcal infection. Choice C is incorrect as the test measures antibodies, not immunity.
