CLINICAL MANIFESTATIONS AND
ASSESSMENT OF RESPIRATORY DISEASE
ACTUAL TEST PAPER WITH VERIFIED
ANSWERS
●● What is hypoxemia?
Answer: Reduction of oxygen in arterial blood (PO2).
●● What is hypercapnia?
Answer: Increased blood carbon dioxide due to inadequate ventilation.
●● What does ventilation refer to?
Answer: The act of breathing, moving air in and out of the lungs.
●● What does respiration refer to?
Answer: The process of gas exchange at the cellular level in the alveoli.
●● What is ventilation/perfusion mismatching?
Answer: A condition where there is an imbalance between air reaching
the alveoli and blood flow in the pulmonary capillaries.
●● What is a common cause of hypoxemia?
, Answer: Inadequate oxygen in the air, respiratory disorders, or
dysfunction of the CNS.
●● What are the clinical manifestations of acute hypoxemia?
Answer: Central cyanosis, increased respiratory rate, tachycardia, and
potential decompensation leading to bradycardia and death.
●● What is the role of the kidneys in chronic hypoxemia?
Answer: The kidneys release erythropoietin to increase red blood cell
production.
●● What are some disorders that lead to poor ventilation?
Answer: Pneumonia, cystic fibrosis, lung cancer, and pleural effusion.
●● What is a common diagnostic tool for assessing hypoxemia?
Answer: Pulse oximetry and arterial blood gases (ABGs).
●● What are some treatments for hypoxemia?
Answer: Supplemental oxygen, bronchodilators, and mechanical
ventilation.
●● What is the physiological effect of hypercapnia?
Answer: It produces respiratory acidosis due to elevated levels of CO2.
