NURS 1327: DAVIS OXGENATION QUIZ. AN ULTIMATE A+
QUESTIONS AND ANSWERS BREAKDOWN.
Gas exchange that occurs in the alveoli-capillary membrane is referred to as what
type of respiration?
A. External
B. Internal
C. Hyperventilation
D. Hypoventilation
A. External
Rationale: External respiration occurs between the alveoli and capillaries where oxygen
and carbon dioxide exchange occurs.
Premature babies are at higher risk for what respiratory problem?
A. Respiratory Distress Syndrome
B. Upper-Respiratory Infection
C. Asthma
D. Airway Obstruction
A. Respiratory Distress Syndrome
Rationale: Due to an undeveloped alveolar surfactant system, premature babies are at
higher risk for developing respiratory distress syndrome (RDS).
An individual has recently moved from the coast of Florida to the Rocky
Mountains in Colorado. What physiological changes will occur over time to
facilitate oxygenation? Select all that apply.
A. Increased RBC production
B. Increased lung volume and pulmonary vasculature
C. Increased ventilation
D. Arterial chemoreceptors stimulate ventilation
E. Irritation of the membranous lining of the lungs
A. Increased RBC production
Rationale: RBC production increases to aid in transporting oxygen to tissues and
organs.
, B. Increased lung volume and pulmonary vasculature
Rationale: Lung volume and pulmonary vasculature increases, which results in an
increase in the surface area enabling alveolar-capillary gas exchange.
C. Increased ventilation
Rationale: Increased ventilation brings more oxygen into lungs.
D. Arterial chemoreceptors stimulate ventilation
Rationale: As fewer oxygen molecules are inhaled, the depletion of oxygen levels
triggers arterial chemoreceptors that stimulate ventilation.
Test-Taking Tip: A change in altitude does not decrease the percentage of molecules of
oxygen in the air; however, the molecules are more spread out.
What is the most common cause of infectious pharyngitis?
A. Streptococcal Pyogenes
B. Staphylococcus Aureus
C. Influenza Virus
D. Respiratory Syncytial Virus
A. Streptococcal Pyogenes
Rationale: Streptococcal Pyogenes is the most common cause of infectious pharyngitis,
otherwise known as "strep throat".
Test-Taking Tip: Most URIs are caused by viruses and are rarely dangerous to healthy
adults and children.
A client presents with cyanosis, tachypnea, and grunting, and reports having
difficulty breathing. What is the immediate action the nurse should take?
A. Ask questions about symptoms while performing a quick examination.
B. Ask extensive questions about occupation factors. smoking habits, and living
environment.
C. Complete a full assessment, including demographic data, health history,
