A 28-year-old primigravida reports experiencing fetal movement for the first time at 24 weeks of gestation. What is the MOST common reason for this delayed perception?
सही उत्तर: घ) Autonomic Nervous System Delay
The limited pelvic diameter, particularly in primiparous women, often delays the first perception of fetal movements (quickening) until approximately 28-30 weeks. The other options can contribute to discomfort but don't explain the delayed onset.

A pediatrician is evaluating a 6-month-old infant presenting with persistent vomiting and signs of dehydration. The initial laboratory findings show elevated levels of serum electrolytes and BUN. What is the MOST probable underlying cause?
सही उत्तर: घ) Todd's Paralysis
Intestinal obstruction, particularly in infants, can lead to significant electrolyte imbalances and elevated BUN due to fluid loss. GERD typically doesn’t cause such marked electrolyte disturbances. Pyloric stenosis is characterized by projectile vomiting with a characteristic halussy fontanelle.

A 32-year-old female presents with gestational diabetes diagnosed at 28 weeks of gestation. Which of the following interventions is MOST crucial to minimize potential complications?
सही उत्तर: ग) Restriction of dietary carbohydrates to
Frequent monitoring of fetal heart rate and uterine contractions is paramount in gestational diabetes management to detect and address fetal distress or hyperkalemia. While carbohydrate restriction is often recommended, it’s not the most immediate critical intervention. Insulin administration is generally reserved for severe cases, and induction of labor at 39 weeks isn’t a standard practice.

A newborn presents with respiratory distress, cyanosis, and intravenous fluid losses. Initial investigations reveal elevated levels of conjugated bilirubin. Which of the following conditions is MOST likely?
सही उत्तर: घ) Crigler-Najjar Syndrome
Gilbert’s Syndrome is a common genetic condition causing unconjugated hyperbilirubinemia, often presenting in newborns with jaundice. The other options involve conjugated hyperbilirubinemia and are less likely in this clinical scenario. Haemolytic anemia and G6PD deficiency cause elevated indirect bilirubin production.

Which of the following best describes the anatomical relationship between the recurrent laryngeal nerve and the cricothyroid muscle? (a) The recurrent laryngeal nerve innervates the cricothyroid muscle directly, controlling its contraction. (b) The cricothyroid muscle is a branch of the recurrent laryngeal nerve. (c) The recurrent laryngeal nerve provides sensory innervation to the cricothyroid muscle, but not motor control. (d) Neither the recurrent laryngeal nerve nor the cricothyroid muscle exist.
सही उत्तर: घ) (d) Neither the recurrent laryngeal nerve nor the cricothyroid muscle exist.
The recurrent laryngeal nerve primarily carries motor fibers that innervate muscles of the larynx (including the cricothyroid), but it does not directly control the muscle's contraction. The cricothyroid muscle is independently innervated by branches of the superior laryngeal nerve. Options (a) and (b) are incorrect.

The enzyme carbonic anhydrase plays a crucial role in maintaining acid-base balance within the body. Its primary function is: (a) Breaking down glucose into energy. (b) Catalyzing the hydration of carbon dioxide to form bicarbonate ions. (c) Transporting oxygen from tissues to the lungs. (d) Synthesizing collagen for tissue repair.
सही उत्तर: ख) (b) Catalyzing the hydration of carbon dioxide to form bicarbonate ions.
Carbonic anhydrase is essential for converting carbon dioxide and water into carbonic acid (H2CO3), a key step in respiration and maintaining pH balance. Options (a), (c) and (d) describe different metabolic processes or protein functions.

Which of the following statements accurately describes the role of pulmonary surfactant in maintaining lung homeostasis? (a) It increases alveolar surface tension, facilitating gas exchange. (b) It decreases alveolar surface tension, preventing alveolar collapse. (c) It reduces blood flow to the alveoli, decreasing metabolic demands. (d) It promotes inflammation within the alveoli, aiding immune defense.
सही उत्तर: ख) (b) It decreases alveolar surface tension, preventing alveolar collapse.
Pulmonary surfactant is a phospholipid mixture that significantly reduces surface tension in the alveoli, allowing them to expand and contract more easily during breathing. Options (b), (c) and (d) describe incorrect functions or actions related to lung physiology.

The process of glomerular filtration in the kidney primarily involves the movement of fluid and small molecules across which membrane? (a) The Bowman’s capsule membrane. (b) The peritubular capillary membrane. (c) The glomerulus filtration membrane. (d) The visceral pleural membrane.
सही उत्तर: ग) (c) The glomerulus filtration membrane.
The glomerulus filtration membrane, formed by the capillaries within the glomerulus and the surrounding Bowman's capsule, is where fluid and small solutes are filtered from the blood. Options (a), (b) and (d) describe other structures involved in kidney function or respiration.

Which of the following best describes the primary function of the sinoatrial node (SA node)? (a) To conduct electrical impulses from the atria to the ventricles. (b) To initiate and regulate the heartbeat through spontaneous depolarization. (c) To filter blood and produce urine. (d) To contract the atrial muscles, propelling blood into the ventricles.
सही उत्तर: ख) (b) To initiate and regulate the heartbeat through spontaneous depolarization.
The SA node is known as the ‘pacemaker’ of the heart due to its ability to spontaneously depolarize, initiating the heartbeat rhythm. Options (a), (c) and (d) describe functions of other parts of the cardiovascular system. Option (b) accurately describes the mechanism of action of the SA node.

What is the primary diagnostic tool used to assess for splenic rupture following blunt abdominal trauma?
सही उत्तर: ग) C. Ultrasound – Focused Assessment with Sonography for Trauma (FAST)
FAST examination is a rapid, bedside ultrasound technique specifically designed to quickly identify free fluid in the abdomen, which would indicate splenic rupture following trauma. CT scans are more sensitive but slower; MRI and plain radiographs aren't as efficient for this acute assessment.
