Multiple Choice
Identify the choice that best completes the statement or answers the question.
____ 1. The nurse is reviewing the arterial blood gas results for a patient with a respiratory disorder. What should the nurse recognize as being the most important chemical regulator of respiration?
| a. | The blood level of oxygen |
| b. | The blood level of nitrogen |
| c. | The blood level of carbon dioxide |
| d. | The amount of hemoglobin in red blood cells |
____ 2. The nurse is reviewing the results of a patient’s pulmonary function tests. Which result describes the air remaining in lungs after normal expiration?
| a. | Tidal volume |
| b. | Expiratory reserve |
| c. | Forced vital capacity |
| d. | Functional residual capacity |
____ 3. The nurse is reviewing the exchange of gases in the blood stream with a patient prescribed oxygen therapy. How should the nurse explain the transport of carbon dioxide in the blood?
| a. | As CO2 in plasma |
| b. | As bicarbonate ions in plasma |
| c. | As hydrogen ions in red blood cells |
| d. | As part of hemoglobin in red blood cells |
____ 4. A patient is having problems with oxygenation of body tissues. What is important for the nurse to consider about the transport of oxygen in the blood?
| a. | It is in blood plasma as free oxygen. |
| b. | It travels on red blood cell membranes. |
| c. | It is bonded to hemoglobin in blood plasma. |
| d. | It is bonded to hemoglobin in red blood cells. |
____ 5. The nurse is reviewing the physiology of the respiratory system with a patient being treated for pneumonia. What structure should the nurse identify as sweeping mucus and pathogens from the nasal cavities and trachea to the pharynx?
| a. | Ciliated epithelium |
| b. | Alveolar macrophages |
| c. | Elastic connective tissue |
| d. | Simple squamous epithelium |
MULTIPLE CHOICE
Carbon dioxide is usually the major regulator of respiration because even small changes in its blood level change the pH. A. Fluctuations in oxygen level have no effect on pH, and an adequate oxygen level in the blood can be maintained even if breathing ceases for a few minutes. B. Nitrogen does not control respirations. D. Hemoglobin level affects tissue oxygenation but is not the most important regulator of respiration.

Functional residual capacity is the air remaining in lungs after normal expiration. C. Forced vital capacity is the maximum amount of air expired forcefully after maximum inspiration. B. Expiratory reserve is the amount of air beyond tidal volume in the most forceful exhalation. A. Tidal volume is the air inspired and expired in one breath.
PTS: 1 DIF: Moderate
KEY: Client Need: Physiological Integrity—Reduction of Risk Potential | Cognitive Level: Application
Most carbon dioxide is carried in the blood in the form of bicarbonate ions in the plasma. A. C. Hydrogen ions do not transport CO2, and it is not carried in plasma as CO2. D. Hemoglobin carries oxygen.
PTS: 1 DIF: Moderate
KEY: Client Need: Physiological Integrity—Physiological Adaptation | Cognitive Level: Application
Hemoglobin carries oxygen in the blood. B. C. Hemoglobin is in red blood cells, not on cell membranes or in plasma. A. Oxygen is not transported free in plasma.
PTS: 1 DIF: Moderate
KEY: Client Need: Physiological Integrity—Physiological Adaptation | Cognitive Level: Application
The mucosa in the nose and trachea is ciliated epithelium; mucus with trapped dust and microorganisms is swept upward toward the pharynx and is usually swallowed. D. Simple squamous epithelium does not have cilia. B. Alveolar macrophages destroy foreign particles in the alveoli, not the trachea. C. Connective tissue does not fight pathogens.
