Question 1

A patient presents with a serum TSH of 0.1 mIU/L and elevated free T4. Which condition does this most likely indicate?

Accepted Answer

Hyperthyroidism

Answer

A suppressed TSH with elevated free T4 is the hallmark of hyperthyroidism, where excess thyroid hormone feeds back to suppress pituitary TSH secretion.

Question 2

Which cranial nerve is responsible for the afferent limb of the corneal reflex?

Accepted Answer

CN V1 (Ophthalmic branch of Trigeminal)

Answer

The ophthalmic branch of the trigeminal nerve (CN V1) carries sensory input from the cornea, forming the afferent limb of the corneal reflex.

Question 3

Kussmaul breathing is a compensatory mechanism most associated with which acid-base disturbance?

Accepted Answer

Metabolic acidosis

Answer

Kussmaul breathing (deep, rapid respirations) is a respiratory compensation for metabolic acidosis, eliminating CO2 to raise blood pH.
