Which of the following statements BEST describes the primary indication for performing an escharotomy in a burn patient (2079)?
सही उत्तर: ख) To relieve tension within the burned skin and facilitate expansion
Escharotomy is specifically indicated when there is excessive tension within the burn eschar, leading to tissue breakdown. This allows for expansion of the skin and relieves pressure. The other options address different aspects of burn management but aren’t the primary rationale for this procedure.

The presence of ‘Battle’s sign’ (hemoperitoneum secondary to splenic rupture) is MOST suggestive of which of the following conditions?
सही उत्तर: ख) Liver abscess
Battle's sign directly relates to hemoperitoneum, which is a hallmark of liver abscesses. While other options can cause abdominal pain and potentially lead to peritonitis, Battle’s sign specifically points towards this etiology. Pancreatitis usually doesn’t present with this finding.

A 35-year-old male presents with severe abdominal pain, nausea, and vomiting. Physical examination reveals guarding and rebound tenderness. Imaging shows a large, inflamed bowel loop causing obstruction. Which of the following surgical approaches is MOST appropriate in this scenario (2079)?
सही उत्तर: ग) Laparoscopic sigmoidectomy
Laparoscopic sigmoidectomy is the most effective and minimally invasive approach for a large, inflamed bowel loop causing obstruction. Total colectomy would be indicated in cases of diffuse colonic disease or severe complications. The other options are either excessively aggressive or less precise than this specific intervention.

Which of the following procedures is MOST commonly used as the initial treatment for a patient presenting with acute appendicitis according to established surgical protocols (2079)?
सही उत्तर: क) Appendicectomy with primary anastomosis
Appendicectomy with primary anastomosis is the gold standard initial treatment for acute appendicitis. The other options represent alternative approaches that are not typically employed as the first-line intervention. Conservative management isn't effective in most cases, while interval appendectomy is reserved for specific situations.

Which of the following best describes the primary role of central chemoreceptors in regulating respiration? (a) Detection of increased carbon dioxide levels in arterial blood (b) Response to changes in pH levels in the cerebrospinal fluid (c) Stimulation by low partial pressures of oxygen in arterial blood (d) Measurement of temperature fluctuations in the brainstem
सही उत्तर: घ) (d) Measurement of temperature fluctuations in the brainstem
Central chemoreceptors located in the medulla oblongata are highly sensitive to changes in carbon dioxide (CO2) levels in cerebrospinal fluid. A rise in CO2 stimulates these receptors, which then increases ventilation rate to expel excess CO2 and maintain blood pH homeostasis. Options (a), (b), and (d) describe other physiological mechanisms.

The ‘suspensory ligament of Treitz’ extends from the lower third of the esophagus to which structure? (a) The diaphragm (b) The ascending aorta (c) The carina of the trachea (d) The vertebral column
सही उत्तर: ग) (c) The carina of the trachea
The suspensory ligament of Treitz attaches to the lower third of the esophagus and its primary function is to support the esophageal hiatus (opening) through which the esophagus passes into the thorax. Option (a) describes the diaphragm’s structure; (c) refers to a respiratory structure, and (d) relates to the vertebral column.

The process of peristalsis in the esophagus relies on rhythmic contractions of smooth muscle, driven by: (a) Sympathetic nervous system stimulation (b) Parasympathetic nervous system stimulation (c) Somatic nervous system stimulation (d) Voluntary muscular control
सही उत्तर: ग) (c) Somatic nervous system stimulation
Peristalsis is mediated by the autonomic nervous system, specifically the parasympathetic nervous system. This system releases acetylcholine, which stimulates smooth muscle contraction to propel food along the digestive tract. (a) and (c) involve conscious control; (d) is incorrect as peristalsis occurs without conscious effort.

Which of the following structures is *primarily* responsible for transmitting proprioceptive information regarding knee joint position? (a) Tibial nerve (b) Femoral nerve (c) Posterior cruciate ligament (d) Anterior tibial nerve
सही उत्तर: घ) (d) Anterior tibial nerve
The posterior cruciate ligament (PCL) is a major stabilizer of the knee and contains proprioceptors that sense joint position and movement, providing crucial feedback for balance and coordinated movements. Options (a), (b), and (d) are peripheral nerves primarily involved in sensation but not specifically proprioception related to joint positioning.

The primary function of the juxtaglomerular apparatus within the kidney is to: (a) Regulate blood glucose levels (b) Produce red blood cells (c) Control renal fluid filtration and blood pressure regulation (d) Transport nutrients from the small intestine
सही उत्तर: ग) (c) Control renal fluid filtration and blood pressure regulation
The juxtaglomerular apparatus consists of the macula densa and the granular cells. The macula densa detects changes in sodium concentration in the distal convoluted tubule, while the granular cells secrete renin, playing a key role in blood pressure regulation and fluid balance. Option (a) is related to pancreatic function, (b) to hematopoiesis, and (d) to digestive processes.

Which of the following findings would MOST likely indicate a diagnosis of congenital heart disease in a newborn infant?
सही उत्तर: ग) C. Absence of Peripheral Pulses
Option B is incorrect because normal variability in heart rate is common in newborns. Option C is incorrect as the absence of peripheral pulses would suggest severe circulatory compromise. The correct answer, option 2 (Persistent Murmur), is a common finding associated with congenital heart defects, indicating abnormal blood flow patterns. Option D is an expected physiological finding in a healthy newborn.
