Correct Answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

Correct Answer: B

Rationale: Type 2 diabetes mellitus is most likely the result of heterogeneous risk factors, such as lifestyle choices and genetics, making it preventable. Type 1 diabetes, on the other hand, is an autoimmune condition that is not preventable. Gestational diabetes occurs during pregnancy and is not entirely preventable. Type 1 and 2 diabetes are distinct conditions, with Type 2 being the type associated with preventable risk factors.

Correct Answer: D

Rationale: It is crucial for new mothers to be aware of potential danger signs after discharge. Poor feeding, high temperature, and convulsions are all critical symptoms that should prompt immediate medical attention. Poor feeding may indicate issues with feeding or underlying health problems. High temperature could be a sign of infection or illness. Convulsions are a serious symptom that could indicate neurological problems or other medical emergencies. By being vigilant and recognizing these signs early, the mother can help ensure the well-being of her newborn. Therefore, the correct answer is 'All of the Above' as all these signs require prompt medical attention to ensure the baby's health and safety.

Correct Answer: C

Rationale: Aortic stenosis is a condition characterized by the narrowing of the aortic valve, leading to reduced blood flow from the heart to the body. This narrowing restricts the amount of oxygenated blood that can reach various tissues, including muscles. As a result, individuals with aortic stenosis may experience exercise intolerance, as their muscles may not receive an adequate oxygen supply during physical activity. This can manifest as fatigue, shortness of breath, and overall decreased exercise capacity. Pallor (choice A) is a pale appearance that may be seen in anemia or other conditions affecting blood flow but is not specific to aortic stenosis. Hyperactivity (choice B) and gastrointestinal disturbances (choice D) are not typically associated with aortic stenosis.

Correct Answer: D

Rationale: To manage the sick child using IMNCI, the correct steps are as follows: Triage based on the severity of illness, Perform a head-to-toe assessment, Identify specific treatments, Provide practical treatment instructions, and Assess feeding while providing counseling. The correct answer, 'D,' focuses on identifying specific treatments, which is crucial in addressing the child's condition effectively. Choice A ('Provide practical treatment instructions') is not the initial step and should come after identifying specific treatments. Choice B ('Triage based on the severity of illness') and Choice C ('Perform a head-to-toe assessment') are essential steps but should follow the identification of specific treatments in the IMNCI approach.
