What is the primary function of hemoglobin in red blood cells?
सही उत्तर: क) A. Transporting oxygen from the lungs to tissues throughout the body.
Hemoglobin’s primary function is binding and transporting oxygen molecules from inhaled air to tissues where it's needed for cellular respiration. Options B & C relate to blood pressure regulation and clotting processes respectively, while option D relates to thyroid hormone production.

A patient presents with severe muscle weakness affecting proximal muscles disproportionately. Blood tests reveal elevated creatine kinase (CK) levels. Which of the following biochemical abnormalities is MOST likely associated with this presentation?
सही उत्तर: ग) C. Mitochondrial dysfunction and impaired oxidative phosphorylation.
Elevated CK levels coupled with proximal muscle weakness strongly suggests mitochondrial dysfunction, as this impairs the ability to perform oxidative phosphorylation – a key energy source for these muscles. Options A & B are incorrect, and option D is physiologically impossible.

-
Which cellular component is most directly involved in the process of oxidative phosphorylation?
सही उत्तर: ख) B. Mitochondria
Oxidative phosphorylation takes place within the mitochondria, where the electron transport chain generates a proton gradient used to produce ATP. The other options are involved in different cellular processes such as protein synthesis, lipid/protein modification and packaging respectively.

The primary role of the hormone aldosterone in maintaining homeostasis is:
सही उत्तर: ग) C. Stimulating the reabsorption of sodium and water by the kidneys.
Aldosterone is a key regulator of electrolyte balance, specifically enhancing sodium and water reabsorption in the distal convoluted tubules of the kidney, leading to increased blood volume. Options A and D are incorrect as aldosterone increases sodium levels, while option B describes the effect of ADH.

Which of the following statements accurately describes the primary function of amylase in the human body?
सही उत्तर: ग) C. Hydrolyzing carbohydrates like starch into simpler sugars such as maltose.
Amylase is an enzyme primarily responsible for breaking down complex carbohydrates (starch) into smaller, absorbable sugar molecules – maltose and glucose. Options A and B describe functions of lipase and glycogen synthase respectively, while option D relates to calcitonin’s role.

A 28-year-old woman is diagnosed with cervical intraepithelial neoplasia grade 2. Which of the following management strategies would be MOST appropriate?
सही उत्तर: ग) Cone biopsy for histological examination and potential excision
A cone biopsy is essential to obtain a tissue sample for accurate diagnosis and to assess the extent of the disease. Following a cone biopsy, further treatment (excising the lesion) is usually indicated based on the pathology results. Observation alone isn’t sufficient for grade 2 CIN. Total hysterectomy isn't typically the initial approach.

A newborn is diagnosed with congenital heart disease characterized by a systolic murmur, cyanosis, and tachypnea. Which of the following conditions is MOST commonly associated with this presentation?
सही उत्तर: ख) Transposition of the Great Arteries
Tetralogy of Fallot, a complex cyanotic heart defect, frequently presents with these symptoms – a systolic murmur, cyanosis, and tachypnea. The other conditions present differently in terms of their physical findings. ASD can be asymptomatic or have milder symptoms.

In a pregnant woman experiencing severe pre-eclampsia, which of the following interventions would be MOST critical to prevent maternal mortality?
सही उत्तर: क) Administration of magnesium sulfate
Magnesium sulfate is the cornerstone in managing seizures associated with severe pre-eclampsia. While other measures might be beneficial, magnesium sulfate directly addresses the most life-threatening complication - status epilepticus. Increased sodium would worsen fluid retention, blood pressure monitoring doesn’t treat the underlying issue, and bed rest alone wouldn't prevent potentially fatal neurological complications.

A 32-year-old woman presents with vaginal bleeding, lower abdominal pain, and a foul-smelling discharge. Based on these symptoms, which of the following conditions is MOST likely?
सही उत्तर: ग) Pelvic Inflammatory Disease (PID)
The combination of vaginal bleeding, lower abdominal pain, and foul-smelling discharge strongly suggests Pelvic inflammatory disease (PID). While other options could cause bleeding, the specific symptoms point most strongly to PID. Hydatidiform mole presents with distinct features absent here. Placenta previa results in vaginal bleeding but not typically a discharge. Normal postpartum bleeding is expected but doesn’t usually involve pain and discharge.

-
Which of the following is the MOST appropriate initial management for a neonate presenting with signs and symptoms suggestive of neonatal sepsis?
सही उत्तर: ख) Perform a rapid blood culture and initiate broad-spectrum antibiotic therapy while awaiting results
Rapid blood cultures and initiation of broad-spectrum antibiotics are crucial in managing suspected neonatal sepsis. Delaying treatment can be catastrophic. The other options are inappropriate - immediate antibiotics without investigation risk antibiotic resistance, passive observation is unacceptable, and simply administering fluids doesn’t address the underlying infection.
