1.
Large heart size is seen in all except
Correct Answer
C. TOF
Explanation
Large heart size is not typically seen in Tetralogy of Fallot (TOF). TOF is a congenital heart defect characterized by four specific abnormalities in the heart's structure. These abnormalities include a ventricular septal defect (VSD), overriding aorta, pulmonary stenosis, and right ventricular hypertrophy. While right ventricular hypertrophy may cause some enlargement of the heart, it is not typically as significant as in other conditions such as VSD or pericardial effusion. Therefore, TOF is the exception in this list of conditions associated with large heart size.
2.
Pericardlal effusion can be most reliable differentiated from congestive cardiac failure by
Correct Answer
B. Presence of pulsus paradoxus
Explanation
Pulsus paradoxus refers to an abnormally large decrease in blood pressure during inspiration. This is a characteristic finding in pericardial effusion, where fluid accumulates in the pericardial sac surrounding the heart, causing compression and impaired cardiac filling. In congestive cardiac failure, the primary pathology is impaired pumping function of the heart, leading to fluid accumulation in the lungs and peripheral tissues. The presence of pulsus paradoxus is a reliable indicator of pericardial effusion and can help differentiate it from congestive cardiac failure.
3.
Systemic hypertension is recognized in following conditions except
Correct Answer
D. Hypothyroidism
Explanation
Systemic hypertension is a common symptom of Takayasu's arteritis, Cushing syndrome, and Moya-moya disease. However, it is not typically associated with hypothyroidism. Hypothyroidism is more commonly associated with hypotension (low blood pressure) rather than hypertension (high blood pressure). Therefore, hypothyroidism is the exception among the given conditions.
4.
Clinical features of constrictive pericarditis include each of the following condition except
Correct Answer
D. Small sized heart
Explanation
The clinical features of constrictive pericarditis include prominently descent in grossly engorged jugular veins, pulsus paradoxus, and a quiet precordium without any murmur. However, a small-sized heart is not a characteristic feature of constrictive pericarditis.
5.
The commonest chromosomal anomaly is
Correct Answer
C. Trisomy 21
Explanation
Trisomy 21, also known as Down syndrome, is the most common chromosomal anomaly. It is caused by the presence of an extra copy of chromosome 21, resulting in physical and intellectual disabilities. Trisomy 13 and trisomy 18 are also chromosomal anomalies, but they are less common than trisomy 21. Fragile X syndrome, on the other hand, is not a chromosomal anomaly but a genetic disorder caused by a mutation in the FMR1 gene.
6.
Most common cause of seizures in a one day old neonate is
Correct Answer
C. AspHyxia neonatorum
Explanation
Asphyxia neonatorum refers to a condition where a newborn experiences a lack of oxygen during birth. This can lead to seizures in a one-day-old neonate. Hypoglycemia, inborn errors of metabolism, and hypocalcemia can also cause seizures in neonates, but asphyxia neonatorum is the most common cause in this specific age group.
7.
The most common complication of Mumps in children is :
Correct Answer
B. Aseptic meningitis
Explanation
Aseptic meningitis is the most common complication of Mumps in children. Mumps is a viral infection that primarily affects the salivary glands. However, it can also lead to inflammation of the protective membranes covering the brain and spinal cord, causing aseptic meningitis. This condition is characterized by symptoms such as headache, fever, stiff neck, and sensitivity to light. While other complications like orchitis (inflammation of the testicles), otitis media (middle ear infection), and myocarditis (inflammation of the heart muscle) can occur in Mumps, aseptic meningitis is the most frequently observed complication.
8.
All of the following are true regarding Diphtheria except:
Correct Answer
A. Causes parotitis
Explanation
Diphtheria is a bacterial infection caused by Corynebacterium diphtheriae. It primarily affects the respiratory system and can lead to severe complications. The given statement "Causes parotitis" is incorrect because diphtheria does not cause parotitis, which is inflammation of the salivary glands. Instead, diphtheria primarily affects the throat and can cause a thick grayish coating to form in the back of the throat, making it difficult to breathe. Other symptoms include fever, sore throat, and swollen lymph nodes.
9.
Commonest cause of anaemia during childhood
Correct Answer
B. Iron deficiency
Explanation
Iron deficiency is the commonest cause of anemia during childhood. Iron is essential for the production of hemoglobin, which carries oxygen in the blood. A deficiency in iron leads to a decrease in the production of hemoglobin, resulting in anemia. Iron deficiency can occur due to inadequate intake of iron-rich foods or poor absorption of iron in the body. It is more common in children who have a diet lacking in iron-rich foods or have increased iron requirements due to rapid growth. Vitamin B12 deficiency, pyridoxine deficiency, and folate deficiency can also cause anemia, but they are not as common as iron deficiency in childhood.
10.
Commonest cause of cholestatic jaundice in newborn is
Correct Answer
C. Idiopathic infantile hepatitis
Explanation
The commonest cause of cholestatic jaundice in newborns is idiopathic infantile hepatitis. This condition refers to inflammation of the liver in infants without a known cause. It is characterized by a blockage in the flow of bile, leading to the buildup of bilirubin and resulting in jaundice. Physiological jaundice is a normal condition that occurs in many newborns and resolves on its own without treatment. Choledochal cyst and galactosemia are other conditions that can cause jaundice in newborns, but they are not as common as idiopathic infantile hepatitis.
