REVIEW QUESTIONS AND CORRECT
ANSWERS
Which physiological process explains why a child who has chills and a temperature of
104° F (40° C) is at risk of developing dyspnea? ✅Fever increases metabolic
demands, requiring increased oxygen need.
In which condition do the lungs remove carbon dioxide faster than it is produced by
cellular metabolism? ✅Hyperventilation
An elderly patient reports to a health care provider office for a routine physical
examination. The patient tells the nurse, "I experience shortness of breath with activity."
The nurse recognizes that which normal physiological change accounts for the patient's
condition? Select all that apply. One, some, or all responses may be correct.
✅Enlarged alveoli
Calcified airways
Changed thoracic shape
Which information is correct regarding physiological factors that affect oxygenation?
✅Carbon monoxide (CO) poisoning decreases the oxygen-carrying capacity of the
blood
The nurse reviews a patient's cardiopulmonary health history and identifies that which
diagnosis impacts cardiac oxygenation? ✅Angina pectoris
Which statement is true regarding respiratory physiology? ✅Ventilation is the process
of moving gases into and out of the lungs.
Which condition involves collapsed alveoli that prevent the normal exchange of oxygen
and carbon dioxide? ✅Atelectasis
Which age population displays an enlarged and calcified trachea and bronchi on an x-
ray? ✅Older adults
Which condition causes bluish discoloration of the skin and mucous membrane?
✅HYPOXIA
Which patient would be experiencing hypoxia caused by increased metabolic rates?
Select all that apply. One, some, or all responses may be correct. ✅Patient who has a
fever
Patient in the third trimester of pregnancy
, Which clinical manifestation is a late sign of hypoxia? ✅CYANOSIS
Which parameter would the nurse monitor in a patient who has developed hypoxia as a
result of severe anemia? Select all that apply. One, some, or all responses may be
correct. ✅PULSE RATE
RESPIRATORY RATE
SKIN COLOR CHANGE
The nurse monitors the oxygen saturation of a patient who is experiencing a cardiac
dysrhythmia. Which is the rationale for the nurse's action? ✅An irregular cardiac
rhythm decreases perfusion.
Which consideration would be included in a diet plan for the patient whose baseline
blood pressure is 170/100 mm Hg and serum cholesterol is 240 mg/dL? Select all that
apply. One, some, or all responses may be correct. ✅Restrict intake of salt
Include chicken
Increase intake of omega-3 fatty acids
Which condition causes decreased tissue oxygenation because of the decreased
oxygen-carrying capacity of the blood? ✅ANEMIA
Which information would the nurse include in an educational session for a group of
nurses regarding physiological factors that prevent adequate oxygenation in patients?
Select all that apply. One, some, or all responses may be correct. ✅ANEMIA
HIGH ALTITUDE
Which condition causes a patient's inability to lie flat, increased blood pressure,
increased pulse, and experience dizziness and a decreased level of consciousness?
✅HYPOXIA
Which information would the nurse share with the patient about the normal mechanism
of respiration? Select all that apply. One, some, or all responses may be correct.
✅Normal breathing is quiet with minimum or no effort.
Ventilation is the process of air moving in and out of the lungs.
The diaphragm is an important muscle that helps in breathing.
Which nursing action would the nurse perform first for the patient lying supine in bed,
short of breath? ✅Raise the head of the bed to 45 degrees
Which intervention is a simple and cost-effective method for reducing pulmonary
secretions stasis and reduced chest wall expansion in a patient who has decreased
mobility? ✅Frequent change of position
