Question 1 of 5
Congenital muscular torticollis is associated with
Correct Answer: A
Rationale: Congenital muscular torticollis is linked to DDH due to shared intrauterine positioning factors.
Question 2 of 5
A 15-year-old male has lost his ability to walk. On physical examination, his ankle and knee deep tendon reflexes are noted to be diminished. The weakness is greatest in peripheral muscles. Cranial nerves all are normal. One week before these symptoms arose, he returned from a camping trip. The most likely diagnosis is
Correct Answer: D
Rationale: Tick paralysis fits this scenario: a camping trip (tick exposure), symmetric peripheral weakness, diminished reflexes, and normal cranial nerves. It resolves with tick removal. Myasthenia gravis causes fatigable weakness; organophosphate poisoning includes autonomic symptoms; spinal muscular atrophy is chronic with atrophy.
Question 3 of 5
Matching: Episodic paralysis
Correct Answer: A
Rationale: Hypokalemia causes episodic paralysis due to potassium shifts affecting muscle function. Other conditions don't feature episodic paralysis.
Question 4 of 5
Matching: External ophthalmoplegia
Correct Answer: D
Rationale: Kearns-Sayre syndrome (mitochondrial disorder) features external ophthalmoplegia. Other conditions don't affect eye muscles this way.
