Progressive spinal muscular atrophy of infancy presents with:
- A. Severe generalised weakness
- B. Fasciculations in the tongue
- C. Loss of spinothalamic tract function
- D. Spontaneous fibrillation on electromyography
Correct Answer: A
Rationale: Progressive spinal muscular atrophy presents with severe weakness and tongue fasciculations. Spinothalamic tract function is preserved, and electromyography shows fibrillation.

In childhood asthma:
- A. Over 90% of patients show exercise-induced bronchoconstriction
- B. Hypercapnia is the first physiological disturbance in status asthmaticus
- C. Infants are unresponsive to bronchodilators
- D. Spontaneous cure occurs before adolescence
Correct Answer: D
Rationale: Spontaneous cure before adolescence is a recognized phenomenon in childhood asthma, though not all cases resolve. Other options are incorrect: exercise-induced bronchoconstriction is common but not universal, hypercapnia occurs late in status asthmaticus, and infants do respond to bronchodilators.
Sinus bradycardia in neonates is considered if sinus rate is
- A. <100 beats/min
- B. <90 beats/min

- D. <70 beats/min
Correct Answer: A
Rationale: Sinus bradycardia in neonates is typically defined as a heart rate <100 beats/min.
SVT in children differ from physiologic sinus tachycardia by all the following EXCEPT
- A. sudden onset and termination
- B. persistent ventricular rate of >180 bpm
- C. fixed RR interval on ECG
- D. evident change in heart rate with activity
Correct Answer: D
Rationale: Physiologic sinus tachycardia can show changes in heart rate with activity, unlike SVT which has a fixed rate.
Dome and dart P wave in lead V1 in electrocardiogram is suggestive of which of the following?
- A. Dextrocardia
- B. Left atrial ectopic rhythm
- C. Biatrial enlargement
- D. Mitral stenosis
Correct Answer: C
Rationale: The dome and dart P wave morphology is characteristic of biatrial enlargement, often seen in conditions like mitral stenosis and atrial fibrillation.
All of the following immune-mediated diseases are associated with antineutrophil cytoplasmic antibody, except
- A. Wegener granulomatosis
