A 10-year-old boy presents with a sudden onset 'slapped cheek' rash, accompanied by a lacy rash extending down his limbs. Which of the following conditions is MOST likely?
सही उत्तर: घ) Rubella
The characteristic features – ‘slapped cheek’ rash and a lacy rash on the extremities - are highly indicative of rubella (German measles). Roseola presents differently, Hand-foot-and-mouth is typically associated with oral lesions and Measles has distinct systemic symptoms.

A pregnant woman presents with severe abdominal pain and vaginal bleeding. Initial investigations reveal a stable hemodynamically, but there is evidence of an ectopic pregnancy. What medication would be the MOST appropriate first-line treatment?
सही उत्तर: ख) Methotrexate
Misoprostol (a prostaglandin analogue) is the standard initial treatment for unruptured ectopic pregnancies, inducing uterine contractions to expel the pregnancy. Methotrexate targets rapidly dividing cells and would be reserved for later stages of management. Hydrocortisone and tranexamic acid are used in different situations.

In a newborn infant demonstrating signs of respiratory distress, what is the generally accepted initial rate for positive pressure ventilation delivered via nasal cannulae?
सही उत्तर: ख) 40-45 breaths per minute
The initial rate for positive pressure ventilation in neonatal resuscitation, as per current guidelines (e.g., 2020), is typically between 30-35 breaths per minute. This ensures adequate oxygen delivery while minimizing the risk of overdistension.

Which of the following hormonal imbalances is MOST commonly associated with primary amenorrhoea in a female presenting with absent uterus and scanty pubic hair?
सही उत्तर: ग) Elevated levels of Oestrogen
Elevated oestrogen levels are strongly linked to primary amenorrhoea, particularly when accompanied by the clinical presentation described – absent uterus and scanty pubic hair. Testosterone and hCG have different roles in female reproductive function, while progesterone is typically involved in maintaining menstruation.

The term ‘engagement’ in obstetrics refers to which of the following?
सही उत्तर: ख) The descent of the fetal head to the level of the ischial spines

A patient undergoes a total hip arthroplasty (THA) for osteoarthritis. Six months post-operatively, the patient reports increasing pain at the surgical site and swelling. Radiographs reveal loosening of the femoral head. What is the MOST likely cause of this complication?
सही उत्तर: ग) C. Nerve damage leading to chronic pain stimulation.
Option 2 is correct, as loosening of the femoral head is a well-recognized complication of THA primarily due to mechanical wear and tear between the articulating surfaces of the prosthetic components. Options A, C, and D represent alternative causes of post-operative pain or complications.

Which enzyme plays a crucial role in converting glucose-6-phosphate into fructose-6-phosphate, representing an early step in glycolysis?
सही उत्तर: ख) B. Hexokinase
Option B is correct – Hexokinase catalyzes the phosphorylation of glucose to glucose-6-phosphate, initiating glycolysis. Options A, C, and D are enzymes involved in later stages or alternative pathways of carbohydrate metabolism.

The process of peristalsis in the digestive tract relies primarily on which physiological mechanism?
सही उत्तर: घ) D. Sequential contractions and relaxations of circular and longitudinal smooth muscles
Option D is correct – Peristalsis involves rhythmic waves of muscular contraction that propel food along the digestive tract. Options A describes a more complex, active mechanism; B incorrectly relates to pressure dynamics; and C inaccurately states that relaxation drives peristalsis.

Which of the following statements accurately reflects the role of mitochondria in cellular metabolism?
सही उत्तर: ग) C. The site of ATP production through oxidative phosphorylation
Option C is correct – Mitochondria are the powerhouses of the cell, generating most of the cellular ATP (adenosine triphosphate) via oxidative phosphorylation. Options A, B, and D describe roles of other organelles like ribosomes, chloroplasts, and lysosomes.

The term ‘glomerular filtration rate’ (GFR) is most closely related to which of the following physiological processes?
सही उत्तर: ख) B. Filtration of water and small solutes from Bowman's capsule into Bowman's space
Option B is correct – GFR directly measures the rate at which fluid is filtered across the glomerulus. Option A describes insulin’s function; C relates to erythropoiesis, and D pertains to the renin-angiotensin system.
