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?
"Stem cells can be used as a source of reserve cells for the entire blood production system."

have produced the trait independently. Which of the following explanations best captures the genetic
explanation for this?

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

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
