Here are the answers to all 40 questions:
Q1. A child able to copy a triangle, ask the meaning of words, climb by alternate feet, help in household tasks, and dress/undress:
Answer: 5 years old
This developmental profile is classic for a 5-year-old child. Copying a triangle, dressing independently, and climbing stairs with alternating feet are all 5-year milestones.
Q2. The Normal reference range for Prothrombin time (PT) is:
Answer: a - 11 to 13.5 seconds
Normal PT is 11-13.5 seconds (INR ~1.0). Values of 14-16 seconds or 7-10.5 seconds are outside the normal range.
Q3. All the following types are primary headaches, EXCEPT:
Answer: d - Headaches caused [by another condition]
Tension, migraine, and cluster headaches are all primary headaches. "Headaches caused by [another condition]" = secondary headaches (e.g., caused by hypertension, infection, tumor). Answer: d.
Q4. All the following types are primary headaches, EXCEPT:
Answer: d - Headaches caused [by another condition]
Same as Q3 - migraine, tension, and cluster are all primary headaches. Any headache attributed to an underlying cause is a secondary headache. Answer: d.

Answer: c - Positive Romberg's sign
Meningeal signs: nuchal rigidity, Brudzinski's sign, Kernig's sign, and Jolt accentuation. Romberg's sign tests proprioception/posterior column function and is a cerebellar/vestibular test - NOT a meningeal sign. Answer: c.
Q9. Disease-specific risk factors of stroke include all conditions, EXCEPT:
Answer: c - Trigeminal neuralgia
Atrial fibrillation and carotid artery stenosis are both direct risk factors for ischemic stroke. Trigeminal neuralgia is a pain condition of CN V and is NOT a stroke risk factor. Answer: c.
Q10. Pain with walking or prolonged standing, radiating from the spinal area into the buttocks, thighs, lower legs, or feet, is named as:
Answer: Neurogenic claudication
This is the classic description of neurogenic claudication from lumbar spinal stenosis. It is differentiated from vascular claudication (DVT/PAD) by its spinal radiation pattern and relief with flexion/sitting.
Q11. Bilateral distal weakness often with sensory loss is mainly caused by:
Answer: d - Peripheral neuropathy (the cut-off option)
Bilateral distal weakness with sensory loss = peripheral neuropathy (stocking-glove pattern). Glucocorticoid treatment causes proximal myopathy; polymyositis and dermatomyositis cause proximal weakness without sensory loss. Answer: d (peripheral neuropathy).

Q14. All are articular structures of the joint, EXCEPT:
Answer: e - Intra-articular ligaments (if listed as extra-articular) OR the cut-off option
Articular structures: articular cartilage, joint capsule, synovium, intra-articular ligaments, articular discs. Periarticular (extra-articular) ligaments are outside the joint capsule. However, the cut-off option e likely refers to bursae - bursae are extra-articular structures. Answer: e (bursae).
Q15. Examining a 25-year-old patient with high fever and severe headache - physical examination in the supine position:
Answer: This describes testing for meningeal signs (Kernig's sign and Brudzinski's sign) in a suspected case of bacterial meningitis. The clinical scenario points to meningitis.
Q16. Kernig's reflex is considered physiological up to the age of:
Answer: b - 2 months
Kernig's sign (resistance to knee extension with hip flexed) is physiological/normal in infants up to approximately 2 months of age, after which it becomes a pathological sign of meningeal irritation.

Rheumatoid arthritis is an autoimmune/immune-mediated inflammatory arthritis. Crystalline arthritis (gout) is metabolic; gonococcal arthritis is infectious; rotator cuff tear is mechanical. Answer: c.
Q18. Which is an extra-articular structure?
Answer: b - Periarticular ligaments
Extra-articular = outside the joint capsule. Periarticular (extra-capsular) ligaments lie outside the joint. Articular cartilage, joint capsule, synovium, and intra-articular ligaments are all within/part of the joint. Answer: b.
Q19. The impaired muscle strength or weakness in the limb is named as:
Answer: b - Paresis
- Paresis = partial weakness/reduced strength
- Paralysis / Plegia = complete loss of movement
- Clonus = rhythmic involuntary muscle contractions (not a term for weakness)
Weakness (partial) = paresis. Answer: b.
Q20. In diabetic patients, condition with slow progression, burning electrical pain, tingling, numbness in the lower extremities:
Answer: Diabetic peripheral neuropathy (distal symmetric polyneuropathy)
This is the classic description of diabetic distal symmetric polyneuropathy - the most common complication of diabetes, presenting with slow-onset burning/tingling/numbness in a stocking-glove distribution.
Q21. Inflammatory causes of joint pain may include all conditions, EXCEPT:
Answer: c - Fibromyalgia
