Feedback: oxygen and carbon dioxide during respiration. The alveoli do not

NURS 325 Exam 3-Fundamentals.
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 Assess the patient’s home for common hazards, including the
Feedback: 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
1.42 out of 1.42 points

NURS 325 Exam 3-Fundamentals.
c.
Pulse oximeter
d.
Yankauer suction tip
catheter
Response A blood pressure cuff is needed. The diastolic aortic pressure is a
Feedback: 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 effects of increased afterload, it will
not help determine the presence of afterload. A Yankauer suction
tip catheter is used to suction the oral cavity.

• Question 5
1.42 out of 1.42 points
The nurse is admitting a patient with uncontrolled diabetes mellitus. It is the
fourth time the patient is being admitted in the last 6 months for high blood
sugars. During the admission process, the nurse asks the patient about
employment status and displays a nonjudgmental attitude. What is the
rationale for the nurse’s actions?
Selected
b.
Answer:
A person’s compliance is affected by economic status.
Answers: a.
Employment status is an internal variable that impacts
compliance.
b.
A person’s compliance is affected by economic status.
c.
Noncompliant patients thrive on the disapproval of
authority figures.
d.
External variables have little effect on compliance.
Response A person’s compliance with treatment is affected by economic
Feedback: status. A person tends to give a higher priority to food and shelter
than to costly drugs or treatments. External variables can have a
major impact on compliance. Employment status is an external
variable, not an internal variable. A person generally seeks
approval and support from social networks, and this desire for
approval affects health beliefs and practices; noncompliance does
not occur from thriving on disapproval of authority figures.
