A patient presents with sudden onset abdominal pain, nausea, and vomiting. Initial examination reveals tenderness in the right lower quadrant. Ultrasound imaging demonstrates an inflamed appendix. Which of the following is the most immediate surgical intervention indicated?
सही उत्तर: क) Appendectomy
Appendectomy is the standard treatment for acute appendicitis. The other options are treatments for unrelated conditions and do not address the presenting symptoms. This question tests basic knowledge of common surgical emergencies.

What is the primary goal of administering Misoprostol in obstetrics?
सही उत्तर: क) To stimulate uterine contractions for labor induction
Misoprostol is a synthetic prostaglandin analogue primarily used to induce uterine contractions and terminate pregnancy. Its mechanism mimics that of naturally occurring prostaglandins involved in labor.

A pregnant woman at 32 weeks gestation presents with sudden onset vaginal bleeding and severe lower abdominal pain. Clinical examination reveals a closed cervical os. Ultrasonography shows a viable fetus. What is the MOST likely diagnosis?
सही उत्तर: ख) Abruptio Placentae
Abruptio placentae is characterized by premature placental separation, causing bleeding and pain. While placenta previa involves the placenta covering the cervix, it typically presents with lighter bleeding and a higher chance of successful delivery. The other options are less likely in this clinical scenario.

In a newborn infant experiencing respiratory distress syndrome (RDS), which of the following interventions would be MOST immediately implemented?
सही उत्तर: ख) Initiating continuous positive airway pressure (CPAP)
Continuous Positive Airway Pressure (CPAP) is the first-line treatment for RDS, providing lung support and improving gas exchange. While other interventions are important in management, CPAP addresses the primary problem of surfactant deficiency.

A 6-month-old infant presents with recurrent episodes of fever, lethargy, and poor feeding. Physical examination reveals signs of carditis (grade III/IV). Which of the following tests is MOST crucial for confirming a diagnosis of acute rheumatic fever?
सही उत्तर: ग) Echocardiogram
An echocardiogram is the gold standard for detecting carditis, which is a major Jones criterion for acute rheumatic fever. While other tests are useful in evaluation, the echocardiogram directly assesses heart damage associated with the disease.

Which of the following clinical features is MOST suggestive of congenital adrenal hyperplasia (CAH) in a newborn infant?
सही उत्तर: क) Hyperpigmentation of the skin
Hyperpigmentation of the skin is a hallmark clinical sign of CAH due to excessive adrenal androgen production. The other options are less specific and can be seen in various neonatal conditions. Excess cortisol, often associated with CAH, frequently causes hypoglycemia.

Which of the following best describes the action of intravenous immunoglobulin (IVIG) therapy? (A) It directly inhibits viral replication. (B) It induces a cytotoxic response against specific cells. (C) It enhances antibody-mediated immunity by providing preformed antibodies. (D) It suppresses the activity of T lymphocytes.
सही उत्तर: ग) It enhances antibody-mediated immunity by providing preformed antibodies.
IVIG provides patients with a pool of previously produced IgG antibodies, offering immediate passive immunization and stimulating an active immune response that is characteristic of antibody-mediated immunity rather than direct viral inhibition or suppression of T cells.

A biopsy sample from the spleen shows a cluster of large, irregularly shaped cells with multiple nuclei. These cells are surrounded by a clear halo of cytoplasm. This finding is most consistent with: (A) Macrophages. (B) Lymphoblasts. (C) Reed-Sternberg cells. (D) Plasma cells.
सही उत्तर: ग) Reed-Sternberg cells.
Reed-Sternberg cells are characteristic of Hodgkin lymphoma and are defined by their large size, multi-nucleated appearance, and the presence of a cytoplasmic halo, making them uniquely identifiable in biopsies.

Which of the following mechanisms primarily contributes to the anti-tumor effect of methotrexate? (A) Inhibition of DNA synthesis. (B) Stimulation of cell proliferation. (C) Enhancement of oxidative phosphorylation. (D) Interference with microtubule formation.
सही उत्तर: क) Inhibition of DNA synthesis.
Methotrexate's key mechanism is inhibiting dihydrofolate reductase, a crucial enzyme in the synthesis of tetrahydrofolic acid – essential for DNA and RNA production, thereby halting rapidly dividing cancer cells. Options B, C, and D represent alternative mechanisms or are incorrect regarding methotrexate’s effects.

The characteristic ‘apple green’ appearance observed during Prussian blue staining of myocardial tissue is most indicative of: (A) Iron deposition. (B) Calcium phosphate crystal formation. (C) Lipid accumulation. (D) Protein aggregates.
सही उत्तर: क) Iron deposition.
Prussian blue staining specifically detects iron within tissues; the resulting ‘apple green’ color is a characteristic visual indicator of iron overload or hemosiderosis. Calcium phosphate and lipid stains produce different colors, and protein aggregates aren't effectively detected with this method.
