Write answer in between .Q:A 17-year-old previously healthy, athletic male suddenly falls unconscious while playing soccer. His athletic trainer comes to his aid and notes that he is pulseless. He begins performing CPR on the patient until the ambulance arrives but the teenager is pronounced dead when the paramedics arrived. Upon investigation of his primary care physicians office notes, it was found that the child had a recognized murmur that was ruled to be benign. Which of the following conditions would have increased the intensity of the murmur?? A: Inspiration, B: Handgrip, C: Valsalva, D: Placing the patient in a squatting position, E: Passive leg raise,  <response>: This is a clinical vignette about a 17-year-old male who collapsed while playing soccer and died. The question asks about a condition that would increase the intensity of his heart murmur, suggesting the murmur may be related to his sudden cardiac death. The choices describe different maneuvers that can alter blood flow and thus change the intensity of murmurs caused by turbulent flow. Inspiration, handgrip, and valsalva increase venous return and cardiac output, which increases murmur intensity. Squatting and passive leg raise decrease venous return and cardiac output, decreasing murmur intensity.Based on the description, the teenager likely had hypertrophic cardiomyopathy, which can cause dynamic outflow tract obstruction. Valsalva would increase the degree of obstruction and murmur intensity in hypertrophic cardiomyopathy.C: Valsalva
