NUR206 EXAM 2 PRACTICE SOLUTION SET
2026 COMPLETE QUESTIONS AND ANSWERS
REVIEW
◉ Why can children have respiratory issues? Answer: more upper
respiratory infections due to high exposure rate in schools
◉ Why can the elderly have respiratory issues? Answer: less muscle
tone
alveoli less elastic leading to reduced lung capacity
prone to pneumonia and hypoxia
◉ What lifestyle factors affect respiratory function? Answer:
smoking, inactivity, obesity, poor nutrition (anemia0
◉ What environmental factors affect respiratory function? Answer:
pollution, asbestos, coal dust, industrial chemicals, high altitude
(less available oxygen), extreme temps, allergies
◉ What is thoracentesis? Answer: procedure where a needle
removes fluid or air from the pleural space
,◉ Why might a thoracentesis be needed? Answer: relieve pressure,
improve breathing, or send fluid for testing
◉ What is a nasopharyngeal/oropharyngeal airway? Answer: plastic
tube placed in the nose or mouth to keep the tongue from blocking
the airway in unconscious or sedated pts
◉ Is a nasopharyngeal/oropharyngeal airway for short term or long
term use? What should the nurse do when one of these is in place?
Answer: short term (emergency)
suctions secretions, monitor airway, take vitals
◉ What is a endotracheal tube? Answer: inserted through the mouth
into the trachea; sterile procedure
emergency or surgery for medical ventilation
◉ What is a tracheostomy? Answer: surgical opening in the trachea
for long-term ventilation; sterile procedure
◉ What is a tracheostomy tube for? Answer: bypasses the mouth
and nose for longer term airway support
, ◉ what is mechanical ventilation? Answer: assisted or complete
ventilation by a ventilator - patient can not breathe on their own
◉ what is spirometry? Answer: A machine to assess the capacities of
the lung and pulmonary function tests - COPD
◉ What is arterial blood gas (ABGs)? Answer: a blood draw from
artery to assess the pH, O2, and CO2 levels of the blood - sterile
procedure
◉ What is pulse oximetry? Answer: a clip with sensor on it is placed
on patient's finger, ear, or forehead to assess oxygen saturation of
the arterial blood
◉ How can pulse oximetry cause an incorrect reading? Answer: can
be inaccurate if patient is anemic, has nail polish, or poor circulation
◉ What is the normal oxygen saturation? Answer: 95-100%
◉ O2 less than 85% results in ____________ Answer: tissue damage
◉ O2 less than 70% results in ____________ Answer: life threatening
emergency
