Upon auscultation at the apex, the APRN hears a grade 3 systolic heart murmur that is soft and blowing in character. What does this finding suggest?
Aortic stenosis (AS)
Mitral valve regurgitation (MVR)
Tricuspid stenosis (TS)
Austin-Flint murmur
The Correct Answer is B
Choice A reason: Aortic stenosis typically presents with a systolic ejection murmur heard best at the right upper sternal border with radiation to the neck. It is often harsh rather than soft and blowing.
Choice B reason: Mitral valve regurgitation produces a holosystolic, soft, blowing murmur best heard at the apex and radiating to the axilla. A grade 3 murmur is moderately loud without a thrill, consistent with this description.
Choice C reason: Tricuspid stenosis produces a diastolic murmur, often heard at the lower left sternal border, sometimes increasing with inspiration. The murmur in this case is systolic and located at the apex, making TS unlikely.
Choice D reason: Austin-Flint murmur is a diastolic murmur associated with severe aortic regurgitation and is heard at the apex. The murmur described here is systolic, not diastolic, and therefore does not fit this diagnosis.

Correct Answer is C
Explanation
Choice A reason: HPV vaccination is recommended for girls and women, but the optimal age for routine vaccination is 11-12 years, not the entire 9-26 age range.
Choice B reason: Similarly, vaccination is recommended for boys and men, with routine administration starting at 11-12 years.
Choice C reason: Routine HPV vaccination is recommended for both girls and boys at ages 11-12 to maximize immune response before potential exposure to HPV, making this the correct age group.
Choice D reason: The vaccine can be given up to age 26, but the recommendation is specifically for children ages 11-12 for routine immunization.
Correct Answer is B
Explanation
Choice A reason: Discontinuing an antidepressant after only two weeks with minimal improvement is premature; SSRIs often require 4–6 weeks for full efficacy.
Choice B reason: Making no changes is appropriate at this stage, as early treatment response is modest. The clinician should continue monitoring and reassess after sufficient treatment duration.
Choice C reason: Adding an augmenting agent is not indicated yet, given the patient has only had two weeks of therapy and lacks significant side effects.
Choice D reason: Switching antidepressants is premature at this early stage of treatment; efficacy assessment requires adequate duration.
