MULTIPLE CHOICE

1. Becky is a nursing student who is completing her clinical rotation on a pulmonary unit. She is documenting her patient assessment. Which of the following best describes the movement of air in and out of the lungs?
A.
Ventilation
B.
Diffusion
C.
Respiration
D.
Perfusion

ANS: A
The lungs assist with 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 body’s organs and tissues.

PTS: 1 DIF: Cognitive Level: Application REF: 801
OBJ: Describe the structure and function of the cardiopulmonary system
TOP: Nursing Process: Assessment MSC: Client Needs: Physiological Integrity

2. Joan is a nursing student who has been studying the cardiopulmonary system. She has been explaining to a patient with chronic obstructive lung disease about how the gasses in the lungs move between the airspaces and the bloodstream. This is best described as which of the following?
A.
Ventilation
B.
Diffusion
C.
Respiration
D.
Perfusion

ANS: D
The lungs assist with ventilation, the movement of air in and out of the lungs, and diffusion, the movement of gases between air spaces and the bloodstream.

4. When giving CPR, Amelia is artificially 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 lungs assist with 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 body’s organs and tissues.

PTS: 1 DIF: Cognitive Level: Knowledge REF: 801
OBJ: Identify the physiological processes involved in ventilation, perfusion, and exchange of respiratory gases TOP: Nursing Process: Assessment
MSC: Client Needs: Physiological Integrity

5. Ginny is a student nurse caring for Harry, a 49-year-old patient, who is experiencing shortness of breath. About which of the following laboratory tests should Ginny be most concerned?
A.
Hemoglobin
B.
White blood cell count
C.
Bilirubin
D.
Creatinine

ANS: A
Hemoglobin transports most oxygen and serves as a carrier for both oxygen and carbon dioxide.
