Weight change may indicate the presence of important underlying
pathology requiring further investigation. Which of the following
,best describes a significant weight change that requires further
evaluation?

decides to undertake a light exercise regimen and loses 15% of

checks her weight irregularly but reports a 5-lb unintended
weight loss over 3 months
c. A 45-year-old recently menopausal female who gains
5% beyond her baseline weight of 140 lb in 6 months
d. A 26-year-old female with a baseline body mass index (BMI)
of 25 who loses 5% of her body weight with 6 months of diet
and exercise modification

A 19-year-old student of art history presents to clinic after a
syncopal (fainting) episode at school. He is notably thin; on a
thorough review of his medical history, he admits that he eats
only minimally to maintain a very low body weight that he
,feels is ideal. He is embarrassed that his issues were
discussed by peers after this episode, especially because he
believes that this is a problem that is only faced by girls and
women. Concerning the two most common eating disorders
(anorexia nervosa and bulimia nervosa), which of the
following statements is true?
a. Men and women are both afflicted, but with a
female:male prevalence ratio estimated at ~2:1.
b. Both of these eating disorders are associated with a body mass
index (BMI) of <17.5.
c. Both of these eating disorders are associated with a real
or imagined fear of appearing fat.
d. Persons with eating disorders are generally easily identified
by their appeara - ANSWER- c. Both of these eating disorders
are associated with a real or imagined fear of appearing fat.
A 55-year-old air traffic control agent reports his home blood
pressure log to clinic after he was diagnosed with hypertension at
a prior visit. He notes that he consistently measures within the
normal range at home, but seems to fall outside the normal range
every time he comes to the clinic. Which of the following blood
pressure measurements is considered to be most accurate (i.e.,
reflecting the patient's "true" blood pressure)?
a. Blood pressure recorded in three positions in the
, health practitioner's office
b. Three separate blood pressure measurements recorded by a
medical technician within 90 minutes of awakening in the
morning in an office setting using an automated device
c. Blood pressure recorded in three positions in the health
practitioner's office after resting for a 10-minute period in a
supine position
d. Regular ambulatory monitoring recorded outside of the office
setting
e. A total of six blood pre - ANSWER- d. Regular ambulatory
monitoring recorded outside of the office setting
A 68-year-old retired college professor presents for routine
physical examination. After the patient has been reading a novel in
the waiting room for ~20 minutes, the technician records his
blood pressure in both arms using an automated device. The
technician notes a 20-mm Hg difference in systolic blood
pressure between the right and left arms; he repeats the readings
10 minutes later and records the same asymmetrical systolic
blood pressure. Which of the following is true regarding this
physical finding?
a. An arm-to-arm difference of up to 20 mm Hg in
systolic blood pressure is considered the upper limits of
normal.
