MULTIPLE CHOICE

 

1. Which term should the nurse use to best describe the movement of air in and out of the patient’s lungs?

a.	Ventilation
b.	Diffusion
c.	Respiration
d.	Perfusion

 

 

ANS:   A

The primary functions of the lungs include ventilation, the movement of air in and out of the lungs, and diffusion, the movement of gases between air spaces and the bloodstream. Respiration is the exchange of oxygen and carbon dioxide during cellular metabolism. The heart supports perfusion, the movement of blood into and out of the lungs to the organs and tissues of the body.

 

PTS:    1                      DIF:    Cognitive Level: Remembering (Knowledge)

REF:    800

OBJ:    Describe the structure and function of the cardiopulmonary system.

TOP:    Nursing Process: Implementation      MSC:   Client Needs: Physiological Integrity

 

2. The nurse is educating a patient who has recently been diagnosed with chronic obstructive pulmonary disease (COPD). The nurse explains how the gasses in the lungs move between the air spaces and the bloodstream. Which process is the nurse describing?

a.	Ventilation
b.	Diffusion
c.	Respiration
d.	Perfusion

 

 

ANS:   B

Diffusion is the movement of gases between air spaces and the bloodstream. One of the primary functions of the lungs includes ventilation, the movement of air in and out of the lungs. Respiration is the exchange of oxygen and carbon dioxide during cellular metabolism. The heart supports perfusion, the movement of blood into and out of the lungs to the organs and tissues of the body.

d.	Perfusion

 

 

ANS:   C

Respiration is the exchange of oxygen and carbon dioxide during cellular metabolism. The primary functions of the lungs include ventilation, the movement of air in and out of the lungs, and diffusion, the movement of gases between air spaces and the bloodstream. The heart supports perfusion, the movement of blood into and out of the lungs to the organs and tissues of the body.

4. When giving CPR, compressions are causing the heart to pump blood into and out of the lungs to the body’s organs. This movement of oxygenated blood is best described as which of the following?

a.	Ventilation
b.	Diffusion
c.	Respiration
d.	Perfusion

 

 

ANS:   D

The heart supports perfusion, the movement of blood into and out of the lungs to the organs and tissues of the body. The primary functions of the lungs include ventilation, the movement of air in and out of the lungs, and diffusion, the movement of gases between air spaces and the bloodstream. Respiration is the exchange of oxygen and carbon dioxide during cellular metabolism.
