The ratio of chest compressions to ventilations in neonatal resuscitation is:
सही उत्तर: क) 3:1
Neonates receive 3 compressions to 1 breath (90 compressions and 30 breaths per minute), because asphyxia is the usual cause of arrest. 30:2 is the single-rescuer ratio for older children and adults.

In neonatal resuscitation, positive pressure ventilation is given at a rate of:
सही उत्तर: ख) 40-60 breaths per minute
PPV at 40-60 breaths/minute is started if the baby is apnoeic, gasping or has heart rate below 100/min after the initial steps. 100-120/min is the compression rate in older children and adults.

Under IMNCI, fast breathing in a child aged 2-12 months is defined as a respiratory rate of:
सही उत्तर: ग) 50 breaths per minute or more
Cut-offs are 60/min under 2 months, 50/min at 2-12 months and 40/min at 12 months to 5 years. Fast breathing is the key sign of pneumonia in this algorithm.

Haemoglobin electrophoresis in beta-thalassaemia major typically shows:
सही उत्तर: ग) Markedly raised HbF
Absent or reduced beta-chain synthesis means little HbA, and gamma chains persist to form HbF, which is markedly raised. HbS is the abnormal haemoglobin of sickle cell disease.

The most common enzyme deficiency causing congenital adrenal hyperplasia is:
सही उत्तर: घ) 21-hydroxylase
21-hydroxylase deficiency (over 90% of CAH) raises 17-hydroxyprogesterone and can cause ambiguous genitalia in girls and salt wasting. 11-beta-hydroxylase deficiency causes hypertension.

-
A sweat chloride concentration consistent with the diagnosis of cystic fibrosis is:
सही उत्तर: क) 60 mmol/L or more
Sweat chloride of 60 mmol/L or above supports CF; 30-59 is intermediate and below 30 is unlikely. The defect is in the CFTR chloride channel.

-
The most common mechanism causing Down syndrome is:
सही उत्तर: ख) Meiotic non-disjunction
About 95% of Down syndrome results from non-disjunction, mostly in maternal meiosis I, and its risk rises with maternal age. Translocation accounts for about 4% and may be inherited.

-
Hypsarrhythmia on EEG is characteristic of:
सही उत्तर: ख) West syndrome (infantile spasms)
West syndrome is the triad of infantile spasms, hypsarrhythmia and developmental regression; ACTH or vigabatrin are used. Absence epilepsy shows 3 Hz spike-and-wave discharges.

-
A simple febrile seizure lasts less than:
सही उत्तर: ग) 15 minutes
Simple febrile seizures are generalised, last under 15 minutes and do not recur within 24 hours in a child aged 6 months to 5 years. Focal, prolonged or recurrent seizures make it complex.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The most common extracranial solid tumour of childhood, with raised urinary VMA, is:
सही उत्तर: घ) Neuroblastoma
Neuroblastoma arises from neural crest cells, often in the adrenal medulla, and secretes catecholamines whose metabolites (VMA, HVA) appear in urine. Wilms tumour is the commonest renal tumour of childhood.
