*B.* initiate prazosin and schedule a follow-up appointment in 6 weeks
*C.* refer the patient for an ultrasound of the prostate and order a PSA
level
*D.* reassure the patient and schedule a follow-up appointment in six
months
*E.* initiate norfloxacin therapy for 7 days and schedule follow-up in
two weeks - ANS>*Answer: C*
This patient has an isolated nodule of the prostate gland — cancer until

present as diffuse enlargement, and not a discrete nodule.

C. The greater the number of concomitant colonic polyps, the greater
the risk of malignant transformatio
D. The majority of colonic polyps are hyperplastic in origin
E. The majority of colonic polyps are > 3 cm in size. - ANS>Answer: E,

Which term is used to describe the characteristic concave or "spoon-
shaped" nails of iron deficiency anemia?
A. leukonychia
B. koilonychias
C. clubbing
D. onycholysis
E. paronychia - ANS>*Answer: B. Koilonychia*
Koilonychia is a spoon-shaping of the nail itself. It is usually a result of
iron deficiency anemia. Leukonychia is often associated with
hypoalbuminaemia that causes partial or complete white discoloration
,of the nails. Leukonychia may also appear as a rare side effect of
systemic chemotherapy in some oncological patients but may also be
present with arsenic poisoning, renal failure pneumonia, or heart
disease. Clubbing of the nails is an actual thickening or elevation of the
nail bed - it is a sign of release of TNF associated with pulmonary
disorders (tissue necrosis factor) typically found in bronchiectasis, lung
cancers and cystic fibrosis (the nails are NOT necessarily cyanotic.)
Onycholysis is a painless separation of the nail from the nail bed.
Several or all nails are usually affected - there are many causes.
Paronychia is an infection of the nail bed and nail margin, usually from
trauma or more commonly, nail-biting.
Which of the following is NOT a characteristic feature of the nephrotic
syndrome?
A. proteinuria
B. hematuria
C. hypoalbuminemia
D. hyperlipidemia
E. generalized edema - ANS>*Answer: B. Hematuria*
Hematuria is present in NEPHRITIC syndrome. Nephrotic syndrome
characteristically includes proteinuria (>3.5 gm/day), with resulting low
serum albumin, hyperlipidemia, hypertension, hypercoagulability, and
generalized edema (from oncotic third-spacing)
, A patient describes a history of recurrent bouts of uveitis. Her chemistry
panel reveals elevated serum calcium and uric acid levels. Her anergy

adenopathy. Which diagnosis is most likely?
A. Silicosis
B. Sarcoidosis
C. Alpha-1 antitrypsin deficiency
D. Histoplasmosis
E. Tuberculosis - ANS>*Answer: B. Sarcoidosis*
Sarcoid typically presents with hilar lvmphadenopathy and
noncaseating granulomas of the lungs (and other organs). In addition,
patients may get eye involvement (uveitis). Elevations of ACE, Calcium
and uric acid are frequently seen.
