Which of the following individuals would be considered to be at risk for the development of
edema?
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?
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:
Negative intrapleural pressure holds the lungs against the chest wall
Increased thrombopoietin levels
,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?
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 blood
to be largely free of plasma proteins?
Bowman Space
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:
"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?
Aortic valve stenosis
"Stem cells can be used as a source of reserve cells for the entire blood production system."
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?
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?
, 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?
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?
Blood backs up into the jugular vein because there are no valves at the point of entry into the
heart.

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
