NURA 303 EXAM 2 COMPLETE
QUESTIONS WITH OUTLINED AND
VERIFIED ANSWERS
\.Nasal Cannula
a low-flow/variable performance device and the most commonly used oxygen delivery device,
for all ages.
Delivers Low flow between 1-6 liters
\.High flow nasal cannula
an oxygen therapy that involves the continuous delivery of an air/oxygen mixture thru a
heater/humidifier.
Delivers flow between 30-60 liters and up to 100% humidified oxygen
\.simple mask
also called nonreservoir mask is a low-flow/variable performance device that is used when a
high oxygen level is needed that can't be obtained from nasal cannula or when cannula is not
appropriate to use.
Delivers flow between 5-10 LITERS
\.partial non rebreather
connected to a reservoir bag to collect the patients first part of exhaled air. has 2 valves. you
rebreathe small amount of outside air. used for pt with low o2 in blood
Deliver flow between 10-15 LITERS
\.non rebreather
delivers highest concentration of oxygen through a low flow mask. similar to partial rebreather
but has one valve between bag and mask. doesn't allow you to breath in outside air
,Flow is greater than 10 L
\.venturi mask
high flow performance device delivering the most precise concentration of oxygen. gives 4-6 L
\.what factors affect accuracy of a pulse ox reading
hemoglobin level
preexisting health conditions like COPD
nail polish
\.when is humidification indicated in supplemental oxygen use
- when patient is experiencing discomfort associated with dry upper respiratory tract mucosa
- if a patient has a tracheostomy or artificial airway
- if a patient is having trouble coughing up sputum
\.what is positive airway pressure
uses mild air pressure to keep airways open delivered via mask
\.types of airway pressure- CPAP
continuous mild air pressure to keep airways open
\.types of airway pressure- BIPAP
bilevel air pressure that changes while the pt breathes in and out
\.types of airway pressure- APAP
auto titrating air pressure that changes based on pt breathing pattern
\.how to instruct pt to use an incentive spirometer
- establish volume goal
- assist pt to be upright or semi-fowlers
- remove dentures if they fit poorly
- place spirometer on flat surface. show patient how to hold spirometer in one hand and hold
tube in the other
- tell pt to exhale normally, then place lips securely around mouthpiece
- tell pt to inhale as slowly and as deeply as they can without using their nose
- pt holds breath for 3-5 seconds
- complete 5-10 times every 1-2 hours
, \.crackles
-heard on inspiration.
-soft, high-pitched intermittent popping sounds.
-occurs when air passes through fluid.
-fine crackles: high pitched
coarse crackles: low pitched, sounds like velcro
-heard in lower lobes
heard commonly with pneumonia, COPD, heart failure and bronchitis patients
\.wheezing
- continuous musical sounds.
- occurs when air passes through constricted airways.
- heard on expiration
-heard all over lungs
heard commonly with asthma or tumor patients.
\.what is the difference between ventilation and perfusion
Ventilation: the flow of air into and out of the alveoli
Perfusion: the flow of blood to the alveolar capillaries
\.inhalation
active process
\.exhalation
passive process
\.bradypnea
decrease in respiratory rate
\.apnea
absence of spontaneous breathing
\.hyperventilation
respiration caused by anxiety
\.eupnea
