Exam Questions and CORRECT Answers
What contribution does the heart and lungs make with oxygenation and perfusion? - CORRECT
ANSWER - Lungs help with oxygenation and heart helps with perfusion
What is perfusion? - CORRECT ANSWER - Gas exchange
What removes CO2 from our blood? - CORRECT ANSWER - Perfusion
What is the normal O2 saturation? - CORRECT ANSWER - 92-100%
What are S/S of hypoxia? - CORRECT ANSWER - Confusion, blue, lethargic
What is the "pacemaker" of the heart? - CORRECT ANSWER - SA node (sinoatrial node)
What is angina? - CORRECT ANSWER - Temporary blockage of a vessel, resulting in
chest pain
What are the two types of angina? - CORRECT ANSWER - Stable and unstable
What is the difference between stable and unstable angina? - CORRECT ANSWER -
Stable- symptoms go away with rest and nitroglycerin
Unstable- symptoms are not relieved with rest or nitroglycerin
What causes heart failure? - CORRECT ANSWER - heart does not pump effectively

Measures the volume of air in liters exhaled or inhaled by the patient over time. The benefit of
using- expands the lungs.
It is a good thing to use 10-15x an hour.
What does the pulse oximetry measure? - CORRECT ANSWER - the peripheral arterial
oxyhemoglobin saturation of the arterial blood (SpO2)
What are the lab studies for the respiratory? - CORRECT ANSWER - Arterial blood gas,
cardiac biomarkers (troponin levels show damage to heart tissue), CBC, cytologic studies
Total Lung Capacity (TLC) - CORRECT ANSWER - what the lungs can hold; measured
by pulmonary function test (PFT)
What should the total cholesterol be? - CORRECT ANSWER - Less than 200
How much O2 can a nasal cannula deliver? - CORRECT ANSWER - Up to 5 liters
How much O2 can a simple mask deliver? - CORRECT ANSWER - 10-15L
