hi guys, anyone knows this answer?
16. A 15-year-old boy is brought to the emergency department 30 minutes after a 2-minute episode of loss of consciousness after completing a 400-meter race. On awakening, he says that he feels fine except for shortness of breath. He weighs 82 kg (180 lb) and is 191 cm (75 in) tall. His blood pressure is 110/70 mm Hg, pulse is 70/min and regular, and respirations are 15/min. The lungs are clear to auscultation. A grade 2/6 systolic murmur is heard at the left sternal border with minimal radiation to the neck; the murmur becomes louder when he stands.
For each patient with loss of consciousness, select the most likely diagnosis.
A
) Aortic stenosis
B
) Carotid sinus hypersensitivity
C
) Conversion reaction
D
) Hypertrophic obstructive cardiomyopathy
E
) Hypoglycemia
F
) Mitral valve prolapse
G
) Orthostatic hypotension
H
) Pulmonary embolus
I
) Seizure
J
) Vasovagal syncope
K
) Vertebrobasilar insufficiency
