The recommended method of screening for overweight in children and adolescents is measuring the child's:

Choice A reason: This is not a good choice. Septic shock is a type of distributive shock that occurs when an infection causes a systemic inflammatory response that leads to vasodilation, hypotension, and organ dysfunction. Septic shock is not the most common type of shock in children, although it can be a serious and life-threatening condition.

Choice B reason: This is not a good choice. Anaphylactic shock is a type of distributive shock that occurs when an allergic reaction causes a severe and rapid hypersensitivity response that leads to bronchoconstriction, angioedema, and hypotension. Anaphylactic shock is not the most common type of shock in children, although it can be a medical emergency that requires immediate treatment.

Choice C reason: This is not a good choice. Distributive shock is a broad category of shock that occurs when there is a loss of vascular tone and blood volume distribution that leads to hypoperfusion and tissue hypoxia. Distributive shock can be caused by various factors, such as sepsis, anaphylaxis, neurogenic injury, or adrenal insufficiency. Distributive shock is not the most common type of shock in children, although it can be a complex and challenging condition to manage.

Choice D reason: This is the correct choice. Hypovolemic shock is the most common type of shock in children. Hypovolemic shock occurs when there is a loss of blood or fluid volume that leads to decreased preload, cardiac output, and blood pressure. Hypovolemic shock can be caused by various factors, such as hemorrhage, dehydration, vomiting, diarrhea, or burns. Hypovolemic shock can be a life-threatening condition that requires prompt fluid resuscitation and correction of the underlying cause.

Choice A reason: This is not a good choice. Watching for signs of cyanosis and administering high dose steroids are not the first steps in managing infective endocarditis. Cyanosis is a late sign of hypoxia and steroids are not indicated for this condition.

Choice B reason: This is the correct choice. Obtaining blood cultures, administering high dose antibiotics, and assessing for cardiac decompensation are the priority interventions for a child with infective endocarditis. Blood cultures are needed to identify the causative organism and guide antibiotic therapy. High dose antibiotics are needed to eradicate the infection and prevent further damage to the heart valves. Cardiac decompensation is a serious complication of infective endocarditis that can lead to heart failure and shock.

Choice C reason: This is not a good choice. Starting high dose antibiotics, obtaining serial blood cultures, and putting the child on high flow oxygen are not the best order of management for infective endocarditis. Blood cultures should be obtained before starting antibiotics to avoid false negative results. High flow oxygen may not be necessary unless the child has signs of hypoxia or respiratory distress.

Choice D reason: This is not a good choice. Obtaining CBC, CXR and starting child on high dose aspirin are not the first steps in managing infective endocarditis. CBC and CXR are useful tests to monitor the infection and the cardiac function, but they are not as urgent as blood cultures. High dose aspirin is not recommended for infective endocarditis as it can increase the risk of bleeding.
