A newborn presents with tachypnea, nasal flaring, retractions, and grunting. The chest X-ray reveals a ground-glass appearance bilaterally. Which of the following is the MOST likely diagnosis in 2024?
सही उत्तर: ख) Respiratory Distress Syndrome (RDS)
RDS, also known as hyaline membrane disease, is the most common cause of tachypnea, nasal flaring, retractions, and a ground-glass appearance on chest X-ray in preterm infants. While pneumonia or bronchiolitis can present similarly, RDS’s characteristic presentation makes it the most probable diagnosis. Pneumonia and bronchiolitis typically show more consolidation.

Which of the following interventions is MOST effective in assessing peripheral arterial disease (PAD) based on ankle-brachial pressure index (ABPI)? a) Ultrasound Measurement of Arteries b) Measurement of Systolic Blood Pressure c) Measurement of Ankle and Brachial Artery Pressures d) Echocardiography
सही उत्तर: ग) c) Measurement of Ankle and Brachial Artery Pressures
The ABPI (ratio of ankle to brachial blood pressures) is the gold standard non-invasive measure for assessing PAD. It directly relates peripheral and central arterial perfusion. The other options are not used for this purpose.

In 2023, what receptor phenotype is most frequently associated with breast cancer in patients carrying germline mutations in the *BRCA1* gene? a) Estrogen Receptor Positive (ER+) b) Progesterone Receptor Positive (PR+) c) HER2-Negative (HER2-) d) Triple Negative Breast Cancer (TNBC)
सही उत्तर: क) a) Estrogen Receptor Positive (ER+)
Germline *BRCA1* mutations are strongly associated with ER+ breast cancers, particularly those with high expression of the estrogen receptor. While TNBC is also linked to *BRCA1*, ER positivity is more direct.

Which of the following conditions is MOST strongly associated with chronic infection with *Schistosoma haematobium*? a) Squamous Cell Carcinoma of the Bladder b) Transitional Cell Carcinoma of the Bladder c) Adenocarcinoma of the Bladder d) Sarcoma of the Bladder
सही उत्तर: ख) b) Transitional Cell Carcinoma of the Bladder
*Schistosoma haematobium* infection is a well-established risk factor for transitional cell carcinoma (TCC), also known as urothelial cancer, of the bladder. Other cancers have different etiologies.

A patient presents with bruising behind the ear following a minor head injury. Which cranial bone is most likely fractured? a) Parietal Bone b) Temporal Bone c) Frontal Bone d) Occipital Bone
सही उत्तर: ग) c) Frontal Bone
Battle’s sign (bruising behind the ear) is a classic indicator of fractures within the temporal bone, which houses important cranial nerves and blood vessels. The other bones have different associated signs of injury.

Dukes’ staging system is primarily utilized for classifying and determining the prognosis of which type of cancer? a) Lung Cancer b) Breast Cancer c) Bladder Cancer d) Colorectal Cancer
सही उत्तर: ग) c) Bladder Cancer
Dukes’ staging (Dukes A-D) specifically describes the stages of bladder cancer based on tumor characteristics, grade, and lymph node involvement. The other options represent cancers with different established staging systems (e.g., TNM for lung cancer).

The Krebs cycle (Citric Acid Cycle) takes place within which organelle?
सही उत्तर: ग) Mitochondrion
The Krebs cycle is a central metabolic pathway occurring within the mitochondrial matrix. This cycle converts acetyl-CoA into carbon dioxide and generates energy carriers. Options 1, 2, and 3 are involved in other cellular processes.

Which hormone primarily stimulates the uptake of glucose from the blood by cells?
सही उत्तर: क) Insulin
Insulin is crucial for lowering blood glucose levels by promoting glucose uptake into cells. This effect relies on its interaction with insulin receptors. Options 2, 3, and 4 are involved in increasing or maintaining blood glucose.

-
Which of the following biochemical reactions contributes most significantly to the breakdown of glycogen?
सही उत्तर: क) Oxidation of fatty acids
The breakdown of glycogen into glucose is primarily achieved through a process called glycolysis. This involves the sequential breakdown of glucose molecules, as opposed to fat oxidation or gluconeogenesis. Option 3 represents glucose synthesis.

In a newborn diagnosed with persistent ductus arteriosus, which of the following medications would be MOST effective in maintaining patency? (a) Ibuprofen (b) Epinephrine (c) Prostaglandin E1 (d) Morphine
सही उत्तर: घ) (d) Morphine
Prostaglandin E1 (PGE1) is the drug of choice for maintaining patency of the ductus arteriosus in newborns by directly constricting the ductal smooth muscle. Options (a), (b), and (d) have different mechanisms and are not effective.
