Which of the following individuals would be considered to be at risk for the development
of edema? -CORRECTANSWER An 81-year-old man with right-sided heart failure and
hypothyroidism
The family of a 68-year-old man who is in the end stages of small cell lung cancer is
distraught at his visible body wasting that has worsened in recent weeks. Which of the
following phenomena best accounts for the patient's anorexia and cachexia? -
CORRECTANSWER Products of the tumor itself as well as a hypermetabolic state
cause cachexia
Which of the following statements best conveys an aspect of the respiratory pressures
that govern ventilation?
Question options: -CORRECTANSWER Negative intrapleural pressure holds the lungs
against the chest wall
Increased thrombopoietin levels -CORRECTANSWER Following a course of measles, a
5-year-old girl developed scattered bruising over numerous body surfaces and was
diagnosed with immune thrombocytopenic purpura (ITP). As part of her diagnostic
,workup, blood work was performed. Which of the following results is most likely to be
considered unexpected by the health care team?
Which of the following situations related to the transition from fetal to perinatal
circulation would be most likely to necessitate medical intervention? -
CORRECTANSWER Pulmonary vascular resistance, related to muscle regression in
the pulmonary arteries, rises over the course of the infant's first week.
At which of the following locations in the nephron would a nurse practitioner first expect

A 51-year-old female patient who is 2 days postoperative on a surgical unit of a hospital
is at risk for developing atelectasis as a result of being largely immobile. Which of the
following teaching points by her nurse practitioner is most appropriate?
Question options: -CORRECTANSWER "You should breathe deeply and cough to help
your lungs expand as much as possible while you're in bed."
A 66-year-old patient's echocardiogram reveals a hypertrophied left ventricle, normal
chamber volume, and a normal ejection fraction from the heart. What is this patient's
most likely diagnosis? -CORRECTANSWER Aortic valve stenosis
"Stem cells can be used as a source of reserve cells for the entire blood production
system." -CORRECTANSWER A couple who are expecting their first child have been
,advised by friends to consider harvesting umbilical cord blood in order to have a future
source of stem cells. The couple have approached their nurse practitioner with this
request and are seeking clarification of exactly why stem cells are valuable and what
they might expect to gain from harvesting them. How can the nurse practitioner best
respond to the couple's inquiry?
A child possesses a trait that is the result of the interaction of two different genes,
neither of which could have produced the trait independently. Which of the following
explanations best captures the genetic explanation for this? -CORRECTANSWER The
outcome is the result of the interaction between collaborative genes.
A 55-year-old man has made an appointment to see his nurse practitioner because he
has been awakening three to four times nightly to void and often has a sudden need to
void with little warning during the day. What is the man's most likely diagnosis and
possible underlying pathophysiologic problem? -CORRECTANSWER Overactive
bladder that may result from both neurogenic and myogenic sources
As a result of dehydration, a patient's epithelial cells are producing insufficient amounts
of mucus. Consequently, the patient's mucociliary blanket is compromised. Which of the
following changes would a care provider most reasonably anticipate as a direct result of
this change? -CORRECTANSWER Increased amounts of bacteria in the lungs. The
primary role of the mucociliary blanket is to trap foreign particles and bacteria and thus
prevent their entry into the lungs. The impaired ciliary function may result in an
, inadequate mucociliary blanket, but the opposite relationship is unlikely. Decreased
oxygen and increased carbon dioxide levels may eventually result, but not as a direct or
immediate consequence.
An 81-year-old female patient of a long-term care facility has a history of congestive
heart failure. The nurse practitioner caring for the patient has positioned her sitting up at
an angle in bed and is observing her jugular venous distention. Why is jugular venous
distention a useful indicator for the assessment of the patient's condition? -
CORRECTANSWER Blood backs up into the jugular vein because there are no valves
at the point of entry into the heart.
Bacterial -CORRECTANSWER Sputum samples from a patient with pneumonia contain
an infective agent that has a peptidoglycan cell wall, expresses endotoxins, replicates
readily in broth and on agar, grows in clusters, has pili, and does not stain when
exposed to crystal violet. This pneumonia is most likely:
A 45-year-old patient who experienced exposure to radiation during an industrial
accident several years prior is being assessed. Which of the following phenomena may
underlie the genetic changes that have been noted in the patient? -
CORRECTANSWER Base pairs may have been rearranged by the radiation exposure.
Splenomegaly and hepatomegaly -CORRECTANSWER A child has been diagnosed
with thalassemia. Which of the following other health problems is the child at risk for?
