Which of the following factors in patients with chronic venous insufficiency predisposes
them to development of skin ulcers?
A. Increased intravascular oncotic pressure
B. Leakage of fibrinogen and growth factors into the interstitial space
C. Decreased capillary leakage
D. Inherited deficiency of protein C - Answer (u) A. Decreased intravascular oncotic
pressure can cause swelling

A 26 year-old monogamous female presents with cyclic pelvic pain that has been
increasing over the last 6 months. She complains of significant dysmenorrhea and

in a patient with a pelvic mass however, ovarian cancer usually occurs in older women
over age 55 and patients are often asymptomatic until the disease is more advanced

A newborn is being evaluated for perioral cyanosis while feeding associated with
sweating. Vital signs are rectal temperature, 37.8 degrees C (100 degrees F), blood
pressure 80/45 mmHg, pulse 180/min, and respirations 40/min. A grade 3/6 harsh
systolic ejection murmur with a single loud S2 is heard at the left upper sternal border.
Electrocardiogram (ECG) shows right ventricular hypertrophy with right axis deviation.
Chest x-ray shows a boot-shaped heart and decreased pulmonary vascular markings.
Which of the following is the most likely diagnosis?
A. Atrial septal defect
B. Total anomalous pulmonary venous return
C. Coarctation of the aorta
D. Tetralogy of Fallot - Answer (u) A. Although the murmur may be consistent with an
ASD with pulmonary hypertension the chest x-ray would not show decreased pulmonary
vascular markings. With a large left to right shunt large pulmonary arteries and
increased vascularity would be seen.
(u) B. The murmur for TAPVR is a soft systolic murmur at the left upper sternal border
with a split S2 in addition to a short mid-diastolic murmur at the low left sternal border.
(u) C. Cyanosis is usually not the presenting sign for coarctation of the aorta. Infants
may present with heart failure, ECG will show evidence of LVH.
(c) D. This is a common presentation for tetralogy of fallot.

identification of pituitary macroadenoma.
(u) B. PET scan is not the modality of choice for the identification of pituitary
macroadenoma.
(u) C. CT of the brain is not the optimal imaging technique for evaluation of the pituitary
stalk.
(c) D. MRI of the brain provides the best visualization of pituitary tumors.

(u) C. Amoxicillin is not indicated for viral infections.
(u) D. Valacyclovir is indicated for Varicella-Zoster virus infection for decreasing the
incidence of varicella pneumonia only. In healthy children valacyclovir is not indicated
