In the male, masculinization of the external genitalia depends on the conversion of testosterone to
dihydrotestosterone by which of the following enzymes?
a.) 17 α-hydroxylase.
b.) Aromatase.
c.) 3 β-hydroxysteroid dehydrogenase.
d.) 5-α reductase. - Correct Answer-(d)
Masculinization of the external genitalia relies on the conversion of testosterone to dihydrotestosterone
by 5-α reductase. Dihydrotestosterone results in (i) enlargement of the genital tubercle, which
ultimately forms the penis; (ii) fusion of the folds of the urogenital sinus, which form the penile urethra;
and (iii) fusion of the labioscrotal folds to form the scrotum.
What feature seen on colonoscopy in campylobacter infectious colitis is helpful in diagnosis?
a.) patchy cobble-stoning of disease
b.) aphthous ulceration mimicking obstruction
c.) Deep geographic & serpiginous ulcers
d.) non-necrotizing peri-cryptic granulomas
e.) caseating granulomas - Correct Answer-(b)
Campylobacter infectious colitis: may see aphthous ulcers on colonoscopy
Concerning acute disseminated intravascular coagulation:
a.) Can be a serious complication during
1|Page
,b.) Infection with gram-positive bacteria is the most common etiology.
c.) Platelets and clotting factors should not be transfused as they will "fuel the fire."
d.) Therapy should be directed primarily at correcting the enhanced fibrinolysis with medication.
e.) Early manifestations are easy bruising and mucocutaneous petechiae - Correct Answer-(a)
Acute DIC is classically described in association with obstetrical emergencies such as abruptio placenta
and amniotic fluid embolism. It is also seen with massive brain trauma.
Angiotensin-converting enzyme is produced by which of the following?
a.) Type I pneumocytes
b.) Type II pneumocytes
c.) Hepatocytes
d.) Juxtaglomerular cells
e.) Vascular endothelial cells - Correct Answer-(e)
Type I alveoli: functional gas exhange; Type II: produce surfactant (decr surgace tension), 1% of avleoli.
Vascular endothelial cells (both pulmonary & renal) however make the ACE
Contraindications to lung-volume reduction surgery include all of the following EXCEPT:
a.) severe kyphoscoliosis
b.) previous thoracotomy or pleurodesis
c.) long-standing history of asthma, bronchiectasis, or chronic bronchitis with production of purulent
sputum
d.) significant coronary artery disease
e.) mean pulmonary artery pressure less than 30 mm Hg - Correct Answer-(e)
Contraindications to lung volume reduction surgery include severe kyphoscoliosis; pulmonary
hypertension (mean pulmonary artery pressure > 35 mm Hg or systolic pressure > 45 mm Hg); significant

,coronary artery disease; previous thoracotomy or pleurodesis; or long-standing history of asthma,
bronchiectasis, or chronic bronchitis with production of purulent sputum.
The following are recognized features of Pancoast's tumour except:
a.) ipsilateral Horner's syndrome
b.) wasting of the dorsal interossei
c.) pain in the arm radiating to the fourth and fifth fingers
d.) erosion of the first rib
e.) weakness of abduction at the shoulder - Correct Answer-(e)
Pancoast tumor involves sympathetic chain (Horner's syndrome) and/or ulnar nerve
A 19-year-old, 66-in., female presents for evaluation of lack of menstruation. On physical examination
she is noted to have scant pubic and axillary hair, with Tanner stage 4 breast development. Pelvic
examination reveals a blind ending vaginal pouch with no palpable uterus. The most likely diagnosis:
a.) Müllerian agenesis.
b.) Turner syndrome.
c.) Complete androgen insensitivity.
d.) Transverse vaginal septum. - Correct Answer-(c)
These individuals present with primary amenorrhea and a blind vaginal pouch. They will have normal
breast development, but will have scanty or lack pubic hair. Their internal genitalia will consist of an
absent uterus and tubes with intra-abdominal testes.
The various forms of 21 hydroxylase deficiency are by far the most common cause of congenital adrenal
hyperplasia.
What percentage of myasthenia gravis patients with no thymoma improve after resection?
a.) 1%
3|Page
, b.) 25%
c.) 50%
d.) 75%
e.) 90% - Correct Answer-(e)
Up to 90-95% improvement in symptoms (only 25% if a thymoma is present)
A 55-year-old man who is a long-term smoker has a 2-cm, irregular, noncalcific lesion in the right upper
peripheral lung on a routine chest x-ray. The only abnormality seen on computed tomographic (CT) scan
is the peripheral nodule. He is asymptomatic except for nightly low-grade fevers. Bronchoscopy is
negative. Management should include:
a.) careful observation with serial chest x-rays
b.) mediastinoscopy
c.) trial of antibiotic therapy
d.) skin tests for tuberculosis and fungi
e.) excision of the lesion - Correct Answer-(e)
This should be assumed to be lung cancer until proven otherwise. Skin tests for tuberculosis & fungi are
appropriate to determine whether the patient has come into contact with these organisms, but would
not provide a diagnosis. The lack of calcification in the lesion makes it unlikely that chronic infection is
the cause.
Which of the following statements concerning thoracic outlet syndrome is true:
a.) Improvement of posture & exercises to strengthen the shoulder girdle are acceptable non-surgical
approaches
b.) The most common presentation is a subclavian vein thrombosis
c.) Triceps weakness & weak wrist flexion are a result of radial nerve impingment
d.) Adson's test is positive with a decreased pulse when the head is turned to the contralateral side
e.) The subclavian vein passes posterior to the anterior scalene - Correct Answer-(a)
