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.
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
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.
significant risk of developing the prerenal form of acute renal
failure? - ✔✔✔✔-A 22-year-old male who has lost a large amount of
blood following a workplace injury
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?
3|Page
, 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
