What is the most common type of shock in children?
septic
anaphylactic
distributive
hypovolemic
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A reason: Chromosomal mutation is not the cause of hypertrophic pyloric stenosis. The exact cause is unknown, but it may be related to genetic, environmental, or hormonal factors.
Choice B reason: Slow feeding will not be sufficient to manage hypertrophic pyloric stenosis. The infant will have persistent vomiting, dehydration, and weight loss due to the obstruction of the pylorus.
Choice C reason: Dietary restrictions will not be effective for hypertrophic pyloric stenosis. The infant will not be able to tolerate any oral intake until the pylorus is surgically corrected.
Choice D reason: Surgery will be necessary to treat hypertrophic pyloric stenosis. The surgery is called pyloromyotomy, which involves cutting the thickened muscle of the pylorus to allow the stomach to empty into the duodenum.
Correct Answer is B
Explanation
Choice A reason: This is not a good choice. Adult heart disease can cause volume overload, but so can pediatric heart disease. Volume overload is a condition where the heart has to pump more blood than normal, which can lead to heart failure and pulmonary edema. Volume overload can be caused by various factors, such as valvular defects, hypertension, or anemia.
Choice B reason: This is the correct choice. Adult heart disease is usually acquired, meaning that it develops over time due to factors such as aging, lifestyle, or infection. Pediatric heart disease is usually congenital, meaning that it is present at birth due to genetic or environmental factors that affect the development of the heart.
Choice C reason: This is not a good choice. Heart failure can occur in both adult and pediatric heart disease. Heart failure is a condition where the heart cannot pump enough blood to meet the body's needs, which can lead to symptoms such as fatigue, shortness of breath, and edema. Heart failure can be caused by various factors, such as coronary artery disease, cardiomyopathy, or arrhythmias.
Choice D reason: This is not a good choice. Digoxin is a drug that can be used for both adults and children with heart disease. Digoxin is a cardiac glycoside that increases the force and efficiency of the heart contractions, slows down the heart rate, and improves the symptoms of heart failure. Digoxin can be used for conditions such as atrial fibrillation, heart failure, or congenital heart defects. However, digoxin has a narrow therapeutic range and requires careful monitoring of the blood levels and the patient's response.
