(b) The reduction of placental volume to alleviate maternal discomfort. (c) The reduction of fetal growth rate through dietary modifications for the mother. (d) The selective extraction of a single embryo during IVF cycles.

A newborn infant presents with a heart rate of 180 bpm, tachypnea, and a bounding pulse. Auscultation reveals harsh systolic ejection murmurs. Which of the following conditions is MOST likely? (a) Tetralogy of Fallot. (b) Coarctation of the Aorta. (c) Atrial Septal Defect (ASD). (d) Ventricular Septal Defect (VSD).
सही उत्तर: घ) (d) Ventricular Septal Defect (VSD).
Option (c) is correct as ASD in newborns typically presents with rapid heart rate and ejection murmurs due to increased blood flow. Options (a), (b), and (d) are congenital heart defects, but do not classically present with such a high heart rate.

Which of the following best describes the primary mechanism of action of Meconium Aspiration Syndrome (MAS)? (a) Severe respiratory distress due to pulmonary edema. (b) Hypoxemia resulting from impaired oxygen exchange across alveolar-capillary membranes caused by meconium obstruction. (c) Bronchospasm triggered by hyperinflation of the lungs. (d) Pneumonia secondary to aspiration of gastric contents.
सही उत्तर: ख) (b) Hypoxemia resulting from impaired oxygen exchange across alveolar-capillary membranes caused by meconium obstruction.
Option (b) is correct because meconium blocks the airways, leading to hypoxia. Options (a), (c), and (d) represent alternative causes or complications of respiratory distress in newborns which are not the primary mechanism of MAS.

A pregnant woman at 36 weeks gestation presents with sudden onset of intense lower abdominal pain. Initial examination reveals a fetal heart rate that is significantly decreased. What is the MOST immediate and appropriate initial management?
सही उत्तर: ग) Administration of intravenous fluids
Magnesium sulfate is the standard first-line treatment for preterm labor, addressing uterine hyperactivity which is the primary cause of fetal distress in this scenario. While other interventions may be needed, magnesium sulfate provides immediate stabilization.

A newborn presents with significant respiratory distress and a palpable mass on the forehead. Examination reveals that this swelling crosses suture lines and was present at birth. What is the most likely diagnosis?
सही उत्तर: क) Pneumonia
A cephalohaematoma (option 0) is characterized by a scalp swelling in newborns that crosses suture lines and appears at birth, aligning with the described presentation. Pneumonia (option 1), brachial plexus injury (option 2), and hydrocephalus (option 3) are all potential causes of respiratory distress but don't typically present with this specific clinical feature.

A 6-month-old infant is brought in for evaluation of failure to thrive. Physical examination reveals hepatomegaly, ascites, and a palpable abdominal mass. What is the MOST likely diagnosis?
सही उत्तर: घ) Infantile Liver Hemangioma
The combination of hepatomegaly, ascites, and an abdominal mass strongly suggests infantile liver hemangioma, a benign vascular tumor common in infants. Celiac disease doesn't typically present with these findings, galactosemia affects carbohydrate metabolism, and inflammatory bowel disease has different manifestations.
