Final Flashcards
What is ventilation?
movement of air in and out of the lungs
What is respiration?
oxygen exchange
Which diagnostic test/exam would best measure a client’s level of hypoxemia? A. Chest x-ray B. Pulse oximeter reading C. ABG D. Peak expiratory flow rate
C. ABG
The term “Kussmaul” refers to a high-pitched, harsh, crowing inspiratory sound that occurs due to partial obstruction of the larynx.
A. True
B. False
false. it is “stridor”
What are the arterial blood gases?
PO2 and PCO2
What are 3 interventions for optimal oxygenation?
mechanical ventilator
chest tube drainage
respiratory meds
You are observing your patient use the incentive spirometry. What demonstration by the patient lets you know the patient understands how to use the device properly?
a. The patient inhales slowly on the device and maintains the flow indicator between 600 to 900 level
b. The patient blows on the mouthpiece rapidly.
c. The patient uses the incentive spirometry once a day
d. The patient rapidly inhales on the devices and exhales
a. The patient inhales slowly on the device and maintains the flow indicator between 600 to 900 level
What does an incentive spirometer do?
promote lung expansion
In caring for a client with a tracheostomy, the nurse would give priority to the nursing diagnosis of
A. Risk for Ineffective Airway Clearance
B. Anxiety Related to Suctioning
C. Social Isolation Related to Altered Body Image
D. Impaired Tissue Integrity
A. Risk for Ineffective Airway Clearance
What are 3 examples of oxygen therapy?
cannula, masks, transtracheal catheter
What is the cardiac cycle?
contraction of the two atria and ventricles
What is electrical conduction?
electrical activity that imitates contraction of the myocardium
What is the SA node?
pacemaker of the heart
What do arteries do in the cardiovascular system?
bring oxygenated blood to tissues
What do veins do in the cardiovascular system?
bring deoxygenated blood back to the heart/lungs
What do the brain stem centers do in the cardiovascular system?
regulate cardiac function and blood pressure
What are 4 factors that influence cardiac function?
lifestyle, heredity, diet, exercise, obesity, stress
Why are cardiac issues more frequent in older adults?
ticker and more rigid valves, decreased myocardial strength, lower exercise tolerance
What is an example of an oxygen transport abnormality?
anemia
When doing a cardiovascular assessment what 4 things do you assess in a physical exam?
pain, fatigue, dyspnea, peripheral circulation
In caring for a client with a blockage of the coronary arteries, the nurse would give priority to the nursing diagnosis of
A. Risk for Ineffective Airway Clearance
B. Anxiety Related to Suctioning
C. Social Isolation Related to Altered Body Image
D. Decreased Cardiac Output
D. Decreased Cardiac Output
