A 5-year-old boy is noted to have a grade II systolic murmur and a widely split S2 murmur on cardiac exam. His vital signs are stable and he has been asymptomatic. Which of the following statement is accurate regarding this child's presentation and likely condition?
A. No further work-up for a presumed venous humB. Chest x-ray, ECG, and echocardiogram would be indicated as next steps to work up a presumed ventricular septal defectC. This patient's murmur is caused by flow through the pulmonary outflow tract and should be evaluatedD. The patient should be scheduled now for cardiac catheterization

C.

Explanation:

The murmur of this patient is possibly caused by an atrial septal defect that induces excessive blood flow through the pulmonary outflow tract, and should be examined.

B is right assess measures but this is not a ventricular septal defect (Vsd) that normally has a holosystolic murmur and a second heart sound that splits with respiration component.

Hence, the correct option is C.

your answer should be c) enjoy!

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
