Nur 355 exam 3 Questions and Answers| New Update with 100% Correct Answers
Hypoxia Low oxygen saturation of the body, not enough oxygen in the blood
hypoxemia deficient amount of oxygen in the blood pao2 less than 60, sao2 less than 90
Dyspena difficult or labored breathing, subjective
Respitory Assessment How do they appear? Skin color, sweating, temperature•
Alert and oriented or confused?•
Are they working very hard to breathe?•
Nares are patent, no visible mucous obstructing breathing•
Are the mucous membranes intact?•
Shape of chest should be symmetrical, movements should be symmetrical.•
Obtain vital signs. Count the respirations without the patient knowing
tactile fremitus (palpation) Palpable vibration from patient speaking "99"
Felt at 2nd intercostal space
Decreased vibration = Excess air or accumulation of fluid
Increased vibration = solid mass or consolidation of secretions or infections
palpate trachea Trachea is midline and freely movable, neck is supple and without masses
normal lung sounds bronchial, bronchovesicular, vesicular
Abnormal lung sounds Rales = fluid in the bases (LA)
Wheezing = bronchial constriction (LA)
Rhonchi = large amount of secretion (midlung)
, Stridor = obstruction in (UA)
Artieral Blood Gas a blood test measures the gases in your blood it records bicarb, co2, ph
and pao2 (invasive)
pulse oximetry An assessment tool that measures oxygen saturation of hemoglobin in the
capillary beds. (non-invasive)
Respiratory age related concerns Osteoporosis, kyphosis, stiffening of muscles and bones•
Decrease in strength of diaphragm, intercostals•
Decreased tissue elasticity•
Airway reactivity combined with delayed response to bronchodilators•
Decreased cough reflex•
Increased neutrophil activity combined with decreased production of macrophages
Nasal cannula flow rate 1-6 L/min
24-44%
Simple face mask flow rate 6-10L/min *should be short-term use*
Partial rebreather mask -delivers a bout 60-65%
-Acceptable flow rate 6-10 lpm
- looks like a non-rebreather without any one-way valves
-Low flow device
-Removal of the one-way valve converts NRB mask into a partial rebreather
Venturi mask A face mask and reservoir bag device that delivers specific concentrations of
oxygen by mixing oxygen with inhaled air.
