NURS 325 - Exam 3: Fundamentals. Questions with Answers. Complete Solutions Guide.
Question 1
1.42 out of 1.42 points
A nurse explains the function
... [Show More] of the alveoli to a patient with respiratory
problems. Which information about the alveoli’s function will the nurse share
with the patient?
Selected
Answer:
a.
Carries out gas
exchange
Answers: a.
Carries out gas
exchange
b.
Regulates tidal
volume
c.
Stores oxygen
d.
Produces
hemoglobin
Response
Feedback:
The alveolus is a capillary membrane that allows gas exchange of
oxygen and carbon dioxide during respiration. The alveoli do not
store oxygen, regulate tidal volume, or produce hemoglobin.
Question 2

A home care nurse is inspecting a patient’s house for safety issues. Which
findings will cause the nurse to address the safety problems? (Select all that
apply.)
Selected
Answers:
a.
Stairway faintly lit
b.
Scatter rugs in the kitchen
c.
Absence of smoke alarms
Answers: a.
Stairway faintly lit
b.
Scatter rugs in the kitchen
c.
Absence of smoke alarms
d.
Level thresholds between bathroom and
bedroom
e.
Bathtub with grab bars
f.
Low-pile carpeting in the living room
Response
Feedback:
Assess the patient’s home for common hazards, including the
following: (1) loose area rugs and runner placed over carpeting, (2)
poor lighting in stairways, and (3) absence of smoke alarms.
Because of reduced depth perception, patients can trip on throw
rugs, runners, or the edge of stairs. A bathtub with grab bars is
safe and does not need to be addressed. Teach patients and family
members to keep all flooring in good repair, and advise them to
use low-pile carpeting. Thresholds between rooms need to be level
with the floor.
Question 3

The nurse suspects the patient has increased afterload. Which piece of
equipment should the nurse obtain to determine the presence of this
condition?
Selected
Answer:
a.
Blood pressure cuf
Answers: a.
Blood pressure cuf
b.
Oxygen cannula
c.
Pulse oximeter
d.
Yankauer suction tip
catheter
Response
Feedback:
A blood pressure cuf is needed. The diastolic aortic pressure is a
good clinical measure of afterload. Afterload is the resistance to
left ventricular ejection. In hypertension the afterload increases,
making cardiac workload also increase. A pulse oximeter is used to
monitor the level of arterial oxygen saturation; it will not help
determine increased afterload. While an oxygen cannula may be
needed to help decrease the efects of increased afterload, it will
not help determine the presence of afterload. A Yankauer suction
tip catheter is used to suction the oral cavity.

windows; and Extinguish the fire using an appropriate
