Which of the following best describes the pathological mechanism underlying septic arthritis?
सही उत्तर: ख) B. Triggered hypersensitivity response involving antibody-mediated activation of neutrophils within the joint space.
Option B is correct because septic arthritis results from bacterial infection triggering a type III hypersensitivity reaction with antibody-mediated neutrophil activation and inflammation within the joint space. Option A is incorrect as viral invasion doesn't directly cause this inflammatory response. Option C is wrong since it describes osteomyelitis, not septic arthritis. Option D misinterprets the changes in synovial fluid.

Temporary hardness of water is caused by: (a) Dissolution of calcium carbonate (b) Presence of magnesium sulfate (c) Reaction with atmospheric gases (d) High levels of iron
सही उत्तर: ख) (b) Presence of magnesium sulfate
Temporary hardness is primarily caused by the dissolution of calcium bicarbonate (which decomposes to calcium carbonate upon heating). The other options represent causes of permanent water hardness. In 2023.

Among routinely used vaccines, the one most sensitive to heat is: (a) Measles vaccine (b) Diphtheria vaccine (c) Oral Polio Vaccine (OPV) (d) BCG vaccine
सही उत्तर: ग) (c) Oral Polio Vaccine (OPV)
Diphtheria vaccines are highly susceptible to heat damage, rendering them ineffective if not properly stored. While all vaccines can be affected by extreme temperatures, diphtheria vaccines exhibit the most pronounced sensitivity. In 2023.

The ‘herd immunity’ concept in disease control refers to:
सही उत्तर: ख) B) The level of immunity within a population that protects those who may not be immune themselves.
Herd immunity describes the protection conferred when a large proportion of a population is immune to an infectious disease. This protects vulnerable individuals who cannot be vaccinated or for whom vaccines are less effective. Option A refers to individual immunity, option C reflects incidence and option D focuses on vaccine efficacy.

Which of the following is the MOST effective method for preventing the spread of Rotavirus infections in young children?
सही उत्तर: ग) C) Vaccination with the Rotarix vaccine.
Vaccination with the Rotarix vaccine is a proven preventative measure against Rotavirus. The other options represent ineffective or potentially harmful interventions. Option A is inappropriate as antibiotics are useless against viruses. Option B is good practice but doesn’t directly prevent the infection.

Which of the following staining techniques is MOST useful in detecting fungal infections of the skin?
सही उत्तर: ख) Periodic acid-Schiff (PAS) stain
The Periodic Acid-Schiff (PAS) stain stains fungi a characteristic magenta color due to their chitinous cell walls. Gram stain fails to detect fungi effectively. *Wright’s* stain is used primarily for blood smears and *H&E* offers no specific advantage in fungal identification.

A 65-year-old male presents with shortness of breath, bilateral crackles, and a history of chronic heart failure. Chest X-ray reveals pulmonary edema. Which of the following drugs is MOST appropriate as an initial treatment?
सही उत्तर: क) Captopril
Captopril, an ACE inhibitor, directly addresses the underlying cause (increased angiotensin II) and reduces fluid retention, a key component of pulmonary edema in heart failure. *Warfarin* and *Clopidogrel* are anticoagulants used for other conditions, not acute heart failure. *Amoxicillin* is an antibiotic and would be ineffective here.

Which pharmacological action is primarily responsible for the neuroleptic effects of Chlorpromazine?
सही उत्तर: ख) Dopamine D2 Receptor Blockade
Chlorpromazine is a potent dopamine D2 receptor antagonist. Blocking this receptor leads to the characteristic antipsychotic effects. While it has some antihistaminic and alpha-blocking properties, its primary therapeutic action rests on dopamine antagonism.

A patient presents with symptoms including fever, chills, and a productive cough with greenish sputum. Gram stain reveals the presence of gram-negative diplococci. Which bacterial infection is MOST likely?
सही उत्तर: ग) Neisseria meningitidis
*Neisseria meningitidis* (meningococcus) are gram-negative diplococci commonly found in patients with the described symptoms. *Streptococcus pneumoniae* is a common cause of pneumonia but typically presents differently on Gram stain. *Haemophilus influenzae* and *Moraxella catarrhalis* frequently cause respiratory infections, however their presentation does not match this case.
