Which component of a sarcomere is directly responsible for muscle contraction?
सही उत्तर: क) Z-disc
The Z-disc marks the boundaries of the sarcomere, and the interaction between actin and myosin filaments (within the A-band, I-band, and H-zone) during muscle contraction is driven by movement at the Z-disc. The H-zone represents the region where thick filaments are present but don't directly participate in power stroke.

Which of the following best describes the primary function of the sinoatrial (SA) node in the heart?
सही उत्तर: ख) To receive and conduct signals from the atrioventricular (AV) node
The SA node, often called the heart's natural pacemaker, generates spontaneous electrical impulses which initiate the heartbeat. The other options describe functions of other components of the conduction system – the AV node relays signals, and the ventricles are stimulated by these impulses. This is based on well-established cardiac physiology.

Whipple’s triad, comprising symptoms of hypoglycemia, confirmed low blood glucose levels, and resolution following glucose administration, is a key diagnostic criterion for which condition?
सही उत्तर: ख) Hypoglycemia
The correct answer is Hypoglycemia. Whipple's triad specifically defines the clinical presentation of hypoglycemia – symptoms like sweating, tremors, confusion (symptoms), a documented low blood glucose reading, and relief upon glucose treatment. The other options represent different metabolic conditions or medical emergencies.

A newborn infant is diagnosed with persistent ductus arteriosus. Which medication would be MOST appropriate to maintain patency of the ductus arteriosus in this case?
सही उत्तर: ग) Prostaglandin E1
Prostaglandin E1 (PGE1) is a commonly used drug to maintain patency of the PDA by stimulating smooth muscle relaxation. Diazepam and Nifedipine are vasodilators, Enalapril is an ACE inhibitor.

A 6-year-old child presents with intermittent episodes of fever, rash, joint pain, and heart murmur. Based on the Jones criteria, which of the following is considered a MAJOR criterion for diagnosing acute rheumatic fever?
सही उत्तर: ख) History of recent streptococcal infection
Evidence of carditis is a major criterion in the Jones criteria, indicating heart damage caused by rheumatic fever. While other options are associated with rheumatic fever, they are only minor or supportive criteria.

Which of the following clinical presentations is MOST suggestive of congenital hypothyroidism?
सही उत्तर: ख) Growth failure and delayed mental development
Growth failure and delayed mental development are classic signs of congenital hypothyroidism. The other options represent symptoms associated with different conditions.

-
Which of the following best describes the mechanism of action of ACE inhibitors in treating hypertension?
सही उत्तर: ख) Blocking sodium reabsorption in the distal tubule
ACE inhibitors work by blocking angiotensin-converting enzyme (ACE), which prevents the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, so inhibiting its production lowers blood pressure. The other options represent alternative mechanisms for managing hypertension.
