• Question 1
1.42 out of 1.42 points
A nurse explains the function 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
Response Feedback:
d.
Produces hemoglobin
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
1.42 out of 1.42 points
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
Response Feedback:
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
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
1.42 out of 1.42 points
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 cuff
Answers: a.
Blood pressure cuff
b.
Oxygen cannula
c.
Pulse oximeter
Response Feedback:
d.
Yankauer suction tip catheter
A blood pressure cuff 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 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 4
1.42 out of 1.42 points
The nurse enters the patient’s room and notices a small fire in the headlight above
the patient’s bed. In which order will the nurse perform the steps, beginning with
the first one?
1. Pull the alarm.
2. Remove the patient.
3. Use the fire extinguisher.
4. Close doors and windows.
