question 73

which of the following pairs measures the oxygen level in the blood?
o chest x - ray and auscultation
o culture and sensitivity
o pulse oximeter and arterial blood gas
o spirometry and carboxyhemoglobin

Explanation:

• For the first question: Hemothorax is defined as the accumulation of blood in the pleural cavity (chest cavity). The prefix "hemo - " means blood and "thorax" refers to the chest.
• For the second question: A lobectomy is the surgical removal of a lobe (a section) of the lung. The term "lob - " refers to a lobe.
• For the third question: A pulse oximeter measures the oxygen saturation (\(SpO_{2}\)) in peripheral blood, and arterial blood gas (\(ABG\)) analysis measures the partial pressure of oxygen (\(PaO_{2}\)) in arterial blood.

Answer:

• First question: blood in the chest cavity.
• Second question: a section of a lung.
• Third question: pulse oximeter and arterial blood gas.
