1. A patient presents with symptoms of carpal tunnel syndrome.
Which nerve is most likely affected?
A) Ulnar nerve
B) Radial nerve
C) Median nerve
D) Musculocutaneous nerve
Correct Answer: C
Rationale: Carpal tunnel syndrome involves compression of the
median nerve as it passes through the carpal tunnel. This leads to
symptoms of numbness, tingling, and pain in the thumb, index
finger, middle finger, and the radial half of the ring finger. The
ulnar nerve (A) would cause symptoms in the 4th and 5th fingers,
and the radial nerve (B) primarily affects the dorsum of the hand.

,2. Which of the following is an autoimmune disorder that
presents with a butterfly-shaped rash across the cheeks and
nose?
A) Rheumatoid arthritis
B) Systemic lupus erythematosus (SLE)
C) Psoriasis
D) Scleroderma
Correct Answer: B
Rationale: The malar (butterfly) rash is a classic sign of Systemic
Lupus Erythematosus (SLE), an autoimmune disorder. This
photosensitive rash appears across the cheeks and bridge of the
nose. Rheumatoid arthritis (A) presents with joint deformities;
psoriasis (C) presents with silvery scales; scleroderma (D) presents

Which of the following medications is NOT typically used for
treatment?
A) ACE inhibitors
B) Calcium channel blockers
C) Tricyclic antidepressants (Sinequan)
D) Beta-blockers
Correct Answer: C
Rationale: Tricyclic antidepressants like Sinequan (doxepin) are not
used to treat hypertension. They are used for depression, anxiety,
and sleep disorders and can actually cause orthostatic hypotension
as a side effect. ACE inhibitors (A), calcium channel blockers (B),
and beta-blockers (D) are all standard antihypertensive
medications.
4. Which hormone plays a key role in the reabsorption of sodium
ions from primary urine in the kidney?
3
, A) Cortisol
B) Aldosterone
C) ACTH
D) ADH
Correct Answer: B
Rationale: Aldosterone is a mineralocorticoid hormone produced by
the adrenal cortex that controls the reabsorption of sodium ions
from the primary urine in the kidney. This action increases blood
volume and blood pressure. Cortisol (A) is a glucocorticoid; ACTH
(C) stimulates cortisol secretion; ADH (D) regulates water
reabsorption.
5. A patient with a history of thyroidectomy complains of tingling
around the mouth and muscle cramps. This suggests:
A) Hypercalcemia
B) Hypocalcemia
