A 6-month-old infant presents with a fever and sudden onset seizure lasting approximately 30 seconds. What is the MOST appropriate initial management?
सही उत्तर: घ) Immediate administration of rectal diazepam
A simple febrile seizure (lasting less than 5 minutes) warrants close observation and monitoring of vital signs. While phenobarbital may be considered, immediate administration is not indicated. Antibiotics are inappropriate without evidence of infection, and rectal diazepam has a slow onset of action.

A newborn presents with projectile vomiting and abdominal distension. An abdominal X-ray reveals a ‘double bubble’ sign. This clinical presentation is MOST likely indicative of:
सही उत्तर: ख) Pyloric stenosis
Pyloric stenosis is the most common cause of vomiting in newborns with a ‘double bubble’ sign on abdominal X-ray. GERD can mimic this presentation, but typically lacks the distinct doubling of the gastric mucosal folds. Intussusception and Meckel's diverticulum are less likely to present with this specific radiographic finding.

Which of the following is a key function of epithelial tissue? (a) Providing structural support for bones. (b) Acting as a barrier between different environments. (c) Producing hormones in endocrine glands. (d) Facilitating gas exchange in the lungs.
सही उत्तर: ख) (b) Acting as a barrier between different environments.
Epithelial tissue specializes in covering surfaces and forming linings, providing protection and acting as barriers. Options (a), (c) and (d) describe functions of other tissue types.

The process of osmosis describes the movement of: (a) Molecules from an area of high concentration to low concentration. (b) Water molecules across a semi-permeable membrane from a region of high water potential to low water potential. (c) Ions in solution. (d) Glucose molecules into cells.
सही उत्तर: ख) (b) Water molecules across a semi-permeable membrane from a region of high water potential to low water potential.
Osmosis specifically refers to the movement of solvent (usually water) across a semi-permeable membrane based on differences in water potential – from an area of higher water potential to lower. Options (a), (c) and (d) describe other types of diffusion.

A patient presents with symptoms of increased thirst (polydipsia) and frequent urination (polyuria). This is most likely due to a problem with: (a) The adrenal glands. (b) The kidneys' ability to reabsorb water. (c) The liver’s production of glucose. (d) The pineal gland’s regulation of melatonin.
सही उत्तर: ख) (b) The kidneys' ability to reabsorb water.
Diabetes mellitus primarily results from a deficiency in insulin, leading to impaired kidney function and the inability to reabsorb water effectively, causing increased urination and thirst. Options (a), (c) and (d) represent different endocrine disorders.

Which of the following best describes the role of the kidneys in maintaining homeostasis? (a) Primarily involved in protein synthesis. (b) Regulating blood volume, electrolyte balance, and pH levels. (c) Producing red blood cells. (d) Absorbing nutrients from the small intestine.
सही उत्तर: ख) (b) Regulating blood volume, electrolyte balance, and pH levels.
The kidneys are central to maintaining homeostasis by regulating fluid and electrolyte balance, as well as acid-base equilibrium in the body. Options (a), (c) and (d) represent unrelated physiological functions.

The primary function of the sinoatrial (SA) node in the heart is to: (a) Conduct electrical impulses from the atria to the ventricles. (b) Generate and initiate rhythmic electrical signals that drive cardiac contraction. (c) Filter blood entering the right atrium. (d) Regulate the rate of breathing.
सही उत्तर: ख) (b) Generate and initiate rhythmic electrical signals that drive cardiac contraction.
The SA node is known as the ‘pacemaker’ of the heart due to its spontaneous generation of electrical impulses. This initiates the heartbeat. Options (a), (c) and (d) represent other functions within the cardiovascular system.

The Glasgow Coma Scale assesses neurological function. The minimum possible score, indicating complete unconsciousness, is which of the following?
सही उत्तर: ख) 4
The Glasgow Coma Scale utilizes a three-part assessment: eye opening, verbal response, and motor response. A score of 3 signifies no discernible responses in any of these categories, indicating complete unconsciousness. Options 4, 5, and 6 represent levels of responsiveness within the scale where some neurological function is still detected.

A newborn infant exhibits persistent jaundice appearing within 24 hours of birth. The infant’s mother has a history of gestational diabetes. Which of the following is MOST likely to be the cause of the infant’s jaundice?
सही उत्तर: घ) Neonatal Jaundice
Newborn jaundice is extremely common, especially in infants with diabetic mothers or those born prematurely due to increased bilirubin production and decreased liver function. While breastfeeding issues and Gilbert's syndrome can cause jaundice, the prompt onset in a diabetic pregnancy strongly points towards neonatal jaundice as the primary diagnosis.

In 2023, a 16-year-old girl is diagnosed with congenital heart disease following prenatal ultrasound. The fetal echocardiogram revealed evidence of twin-to-twin transfusion syndrome (TTTS). Which of the following statements regarding TTTS is MOST accurate?
सही उत्तर: ख) It is more common in monochorionic twins
TTTS primarily occurs in monochorionic twins (where the fetuses share a placenta) which are most susceptible to vascular mismatch. Identical twins cannot develop TTTS as they share the same placental circulation. While TTTS can result in fetal demise, it is frequently treatable with interventions targeting the placental vessels.
