Which of the following interventions would be MOST appropriate for the initial management of respiratory distress in a preterm infant (under 32 weeks gestation) exhibiting signs of RDS (Respiratory Distress Syndrome)?
सही उत्तर: ग) Initiation of surfactant therapy
Initiating surfactant therapy is the standard and most effective initial intervention for preterm infants with RDS. A Nasal Gastric Tube should be avoided as it can cause aspiration. Continuous gastric residual pressure monitoring and manual ventilation are supportive measures but not the primary treatment.

A pregnant woman at 20 weeks gestation presents with sudden onset of severe headache, visual disturbances, and transient proteinuria. Which of the following blood pressure readings would be MOST indicative of pre-eclampsia?
सही उत्तर: ग) 160/100 mmHg
Pre-eclampsia is defined as new-onset hypertension with proteinuria or end-organ dysfunction. A blood pressure reading of 140/90 mmHg strongly suggests pre-eclampsia in a pregnant woman presenting with these symptoms.

What is the MOST likely diagnosis in a newborn exhibiting characteristic 'olive-shaped' testes?
सही उत्तर: घ) Cryptorchidism
The olive-shaped testes in newborns signifies undescended testicles. Klinefelter syndrome involves a male with an extra X chromosome, Congenital Adrenal Hyperplasia causes virilization and ambiguous genitalia, and Cryptorchidism is the general term for undescended testicles.

Which hormone primarily regulates the reabsorption of sodium in the distal convoluted tubule and collecting duct of the nephron? (A) Antidiuretic Hormone (ADH) (B) Aldosterone (C) Atrial Natriuretic Peptide (ANP) (D) Parathyroid Hormone (PTH)
सही उत्तर: ख) (B) Aldosterone
Aldosterone, secreted by the adrenal cortex, plays a major role in sodium reabsorption, directly influencing water balance. ADH is primarily involved in water reabsorption and options (C) and (D) have different primary functions.

A pregnant woman presents with severe abdominal pain. Ultrasound reveals a large fibroid that has significantly increased in size during the second trimester. Which of the following is the MOST probable explanation for this presentation?
सही उत्तर: ख) B) Rapid uterine growth and vascular congestion within the fibroid
Option B is correct. The key factor here is the second-trimester timing, which correlates with significant fetal growth and subsequent pressure on the uterus. This increased pressure can cause vascular congestion within the fibroid, leading to acute pain.

Which of the following symptoms is most indicative of early pregnancy, as described by Hegar's sign?
सही उत्तर: ग) C) Palpable Uterine Soft Encasement
Option C represents Hegar’s sign. This palpable uterine soft encasement is a characteristic physical finding in early pregnancy, demonstrating the expanding uterus and fluid accumulation. The other options can occur in early pregnancy but don't specifically define this key indicator.

In evaluating a newborn’s gestational age, which of the following findings is generally associated with a significantly advanced gestational age?
सही उत्तर: घ) D) Measurement of Head Circumference >35 cm
Option D is correct. A head circumference exceeding 35 cm (approximately 14 inches) typically indicates a gestational age greater than 37 weeks, indicating the fetus has reached a more advanced stage of development and growth.

A 6-month-old infant presents with bilateral edema, hematuria, and hypertension. Laboratory tests reveal elevated serum creatinine and proteinuria. Which of the following conditions is MOST likely?
सही उत्तर: ख) B) Post-Streptococcal Glomerulonephritis
Option B is correct. The presentation – edema, hematuria, hypertension, and proteinuria – strongly suggests post-streptococcal glomerulonephritis, a common autoimmune condition often following a streptococcal infection. While other options could present similarly, the combination points to this specific diagnosis.

What is the primary physiological effect of magnesium sulfate administered during labor that contributes to its potential toxicity?
सही उत्तर: ग) C) Direct blockade of neuromuscular transmission and decreased myotonia
Option C is correct. Magnesium sulfate’s primary mechanism in labor involves blocking voltage-gated calcium channels, reducing muscle excitability (including uterine muscles), and consequently decreasing contractions. The other options represent potential but less direct effects or actions of magnesium.

The primary function of pancreatic lipase in the digestion of fats involves breaking down triglycerides into which of the following products?
सही उत्तर: ग) Monoglycerides and Fatty Acids
Pancreatic lipase hydrolyzes (breaks down) triglycerides, the main components of dietary fat. This reaction yields monoglycerides and fatty acids, facilitating their absorption into the body. Phospholipids are digested by phospholipase A2; steroids by cytochrome P450 enzymes; amino acids by proteases.
