A pediatrician is examining a 6-month-old infant presenting with acute diarrhea. Based on current WHO guidelines, what zinc supplementation dosage would be recommended for this child?
सही उत्तर: ख) 20 mg/day
WHO recommends a daily dose of 20 mg of zinc sulfate for children with acute diarrhea above six months. This is due to zinc's role in supporting the immune system and inhibiting diarrheal pathogens. A higher dosage (30 or 40mg) could be toxic while a lower one (10mg) may not provide sufficient benefit.

A pregnant woman in her third trimester develops sudden onset of severe headache, visual disturbances, and hypertension. What is the most likely diagnosis?
सही उत्तर: ग) Eclampsia
The presentation of severe headache, visual disturbances, and hypertension during pregnancy strongly suggests Eclampsia, characterized by a sudden increase in blood pressure with neurological symptoms. Gestational hypertension is defined as elevated blood pressure without other signs of preeclampsia; preeclampsia adds proteinuria or organ dysfunction, which are not indicated here.

In a breech presentation during vaginal delivery, what is the MOST important factor influencing the likelihood of successful vaginal delivery?
सही उत्तर: ख) Maternal Muscle Tone
Fetal head size and position are critical in breech presentations. A smaller fetal head will make delivery more difficult. Maternal muscle tone, placental location, and fetal weight have less direct influence on the vaginal delivery outcome compared to the fetal head’s ability to pass through the pelvis.

A 3-year-old child presents with fatigue, irritability, and a maculopapular rash that started on the trunk and spread to the extremities. Physical examination reveals enlarged lymph nodes. Which condition is MOST likely?
सही उत्तर: ग) Roseola Infantum
Roseola infantum (sixth disease) presents with high fever followed by a maculopapular rash that typically starts on the trunk and spreads to the face, neck, and extremities. Measles is also characterized by a maculopapular rash but often involves respiratory symptoms like cough and coryza. Chickenpox presents with vesicles and rubella with slightly different rash characteristics.

A neonate presents with persistent cyanosis despite treatment with oxygen. Chest X-ray reveals an ‘egg-on-a-string’ cardiac silhouette. This finding is MOST suggestive of:
सही उत्तर: ख) Tetralogy of Fallot
The 'egg-on-a-string' appearance on chest X-ray, indicative of a slender aorta, is characteristic of Tetralogy of Fallot, a cyanotic congenital heart defect. Pulmonary hypertension would present differently, while transthyroid disease and rubella syndrome have different clinical presentations.

A newborn infant with persistent vomiting and irritability has a palpable abdominal mass. Which of the following conditions is MOST likely?
सही उत्तर: ख) Pyloric Stenosis
Pyloric stenosis, characterized by an enlarged pyloric antrum and forceful vomiting, presents with a palpable abdominal mass. Intussusception involves telescoping of the bowel, also causing vomiting and pain. Gastroesophageal reflux is not typically associated with a palpable mass. Hirschsprung's disease involves absence of nerve cells in the colon.

In a singleton pregnancy, how does fetal urine production contribute to polyhydramnios?
सही उत्तर: ग) Stimulation of amniotic fluid secretion
Fetal urine production is the primary driver of polyhydramnios in a singleton fetus. Decreased fetal renal function would not lead to increased urine output. Increased placental perfusion and direct hormonal effects are not the main contributors. Stimulation of amniotic fluid secretion is a secondary consequence.

A 6-month-old child presents with fever, lethargy, and a characteristic “washerwoman sign” (a blanching rash appearing in streaks on the limbs). The most likely diagnosis is:
सही उत्तर: क) Kawasaki Disease
Kawasaki disease classically presents with a fever, rash resembling a ‘washerwoman’s hands,’ conjunctivitis, and changes to the mucous membranes. Roseola is characterized by high fever followed by a maculopapular rash. Measles and rubella present with different types of rashes and are less likely given this specific presentation.

Which of the following is the primary mechanism by which skin-to-skin contact prevents neonatal hypothermia?
सही उत्तर: घ) Direct heat transfer
Skin-to-skin contact facilitates direct heat transfer from the mother's body to the infant, warming the baby effectively. Increased metabolic rate and vasoconstriction would actually *reduce* heat loss. Improved vascular permeability is not a mechanism for heat regulation.

A pregnant woman presents with severe lower abdominal pain, vaginal bleeding, and fetal parts palpable vaginally. The most likely diagnosis is:
सही उत्तर: ख) Abruptio Placenta
Abruptio placenta (placental abruption) is characterized by premature separation of the placenta from the uterine wall, causing bleeding and fetal parts to be felt vaginally. The other options are less likely given the specific clinical presentation described. Placenta previa typically involves bleeding around the cervix, while miscarriage involves fetal demise and expulsion. Ectopic pregnancy involves implantation outside the uterus.
