Block 1
1. A 3−month old infant with DiGeorge syndrome is brought to the office by his mother 1 week after a 2−week hospitalization
for treatment of an abscess at a previous intravenous site. This was the patient’s second serious infection requiring
admission to the hospital, and his mother thinks that he is getting sick again. She says his temperature this morning was
38.5C (101.3F) and he has not shown interest in feeding today. He was born at term. Physical examination at birth showed
a cleft palate. Echocardiography obtained at birth disclosed a right−sided aortic arch. The infant is 50cm (20 in; 10th
percentile) long and weighs 4593 g (10 lb 2 oz; 3rd percentile); head circumference is 38 cm (15 in; 3rd percentile). Vital
signs now are temperature 38.0C (100.4F), pulse140/min, respirations 28/min, and blood pressure 92/58 mm Hg. Physical
examination discloses a tender area of induration with erythema on the right foot. You suspect the infant has a cellulitis
and arrange for admission to the hospital. Which of the following is the most likely cause of his recurrent infections?
A. Congenital heart defect
B. Hypogammaglobulinemia
C. Insufficiently treated prior infection
D. Malnutrition
E. T−lymphocyte deficiency
2. A 15−year−old boy is brought to the office by his mother 1 hour after having an episode of weakness and numbness of all
extremities, loss of vision, and syncope. The episode lasted 10 minutes, after which he regained consciousness and was
normal. Two weeks ago he had a surfing accident, during which he struck his head and neck on the surfboard. He did not
seek medical attention at the time. On questioning now in the office, he says that since the accident he has had
intermittent episodes of vertigo that have lasted 5 minutes each. Vital signs are normal. Physical examination discloses no
abnormalities. Which of the following are most appropriate next step in evaluation?
A. EEG
B. Emergent MRI/MRA of the brain and cervical spine
C. C. Observation at home
D. Observation in the hospital with plans to reevaluate if he has another syncopal episode

3. A 74−year−old white man comes to the office for evaluation of his blood pressure, which recently showed two sparate
readings of 180/74 mm Hg and 176/78 mm Hg You review this chart and see that his last visit was 3 years ago, at which
time his blood pressure was 164/80 mm Hg. He currently takes no medication. He is 183 cm (6ft) tall and weighs 79 kg
(175 lb), BMI is 24 kg/m^2. Physical examination is normal except for a blood pressure of 170/80 mm Hg. You recommend
an exercise program and diet modification with decreased salt intake. At a follow0up visit 3 months later he has lost 2.2 kg
(5 lb). He says he restricted his salt intake, however, his blood pressure remains elevated at 168/70 mm Hg. You
recommend a trial of pharmacotherapy. You have reviewed the results of a randomized controlled trial assessing the
effects of antihypertensive treatment to reduce the risk for stroke. In this study, 4736men and women with elevated
systolic blood pressure were randomly assigned to a placebo, diuretic, or cardioselective beta−blocking medication.
Patients were monitored for 5 years. The effects of treatment on blood pressure are shown in the table below.
Change in blood pressure (mean mm Hg +/- standard deviation)
Assignment Systolic Diastolic
Placebo −2 +/− 4.2 +1.5 +/− 3.6
Diuretic −12.2+/−6.8* −3 +/− 4.2
Beta−blocking medication −14.3 +/− 10.7** +0.8 +/− 6.9
*p = 0.002, **p<0.01 (compared with placebo)
Item 1 of 2:
Compared with the placebo, which of the following is the most appropriate conclusion based on these data?
A. Beta−blocking medication decreases diastolic blood pressure
B. Beta−blocking medication decreases diastolic blood pressure more than the diuretic
C. Diuretic decreases diastolic blood pressure
D. Diuretic decreases systolic blood pressure
, lOMoAR cPSD| 22891787
E. Diuretic plus beta−blocking medication acts synergistically to decrease bood pressure

macular degeneration and she is not very mobile. After disimpaction and recovery, she falls and breaks her hip on the
second hospital day. You refer to a case−control study of in−hospital hip fractures that notes an odds ratio of 2.0 (95%
confidence interval [CI], 1.2 to 3.3) for the presence of vision impairment. Which of these following is the most
appropriate statement regarding the 95% CI in this study?
A. On repeated trials, the probability that the odds ratio falls outside 1.2 and 3.3 is 5%

up examination. She brings her fingerstick blood glucose log to the office and says, <I check my sugar about the three
times weekly and it has been running high lately.= Medical history is also significant for hypertension, hypercholesteremia,
and coronary artery disease, for which she underwent three−vessel coronary artery bypass grafting 2 years ago.
