Question | Answer |
---|---|
person breaths in air but it gets stuck in their lungs and can't exhale all the air from their lungs, resulting in the barrel-chested look, in a patient with | COPD |
Because patients w/COPD fully exhale, there is a build-up of | CO2 in the lungs |
The drive for a person to breath islcaused by the low CO2 levels which stimulates the body to | intake more oxygen/air. |
If you give a person with COPD high level of __, more CO2 will build up in their body further decreasing their respiratory rate. | oxygen |
In newborns born very prematurely, growth of the blood vessels supplying the __ may stop for a period of time & when growth resumes, it occurs in a disorganized fashion. | retina |
during disorganized rapid growth, the small blood vessels may bleed and eventually lead to __ | scarring |
may also increase the risk of retinopathy of prematurity | high blood oxygen levels |
In the most severe cases,disorganized rapid growth may ultimately result in __ of the retina from the back of the eye and loss of vision | detachment |
involves abnormal development of lung tissue, characterized by inflammation and scarring in the lungs | bronchopulmonary dysplasia |
bronchopulmonary dysplasia develops in __ __ __ who have received high levels of oxygen for long periods of time or who have been on a ventilator during treatment for respiratory distress syndrome | severely ill infants |
bronchopulmonary dysplasia is __ __ in infants born early (premature) whose lungs were not fully developed at birth. | more common |
insufficient oxygen | hypoxia |
can be administered via endotracheal intubation, nasal cannula, masks, tents, & hoods | oxygen |
O2 delivered at high concentration/prolonged periods of time can cause hypoventilation, particularly w/COPD leading to CO2 retention & | acidosis |
O2 delivered at high concentration/prolonged periods of time can lead to | confusion |
O2 delivered at high concentration/prolonged periods of time can lead to changes in the __ of the lungs | alveoli |
O2 delivered at high concentration/prolonged periods of time can lead to __ in premature infants | blindness |
smoking, matches & electrical equipment that may spark are __ __ in rooms were O2 is used | not allowed |
act by relaxing smooth muscles of bronchial tree, thereby relieving bronchospasm & increasing vital capacity of lungs | bronchodilators |
bronchodilators are used in symptomatic treatment of acute resp. conditions such as | asthma/COPD |
potent bronchodilators that increase vital capacity & decrease airway resistance | sympathomimetics |
sympathomimetics work on smooth muscle in lungs to cause | relaxation |
sympathomimetics can affect the entire __ nervous system | sympathetic |
ease of use, efficacy & portability are all | advantages of MDIs |
manufacturers are DC productions of MDIs due to the | ban on CFC |
provide medication only under pressure of inspiration, rather than through compression valve | breath-actuated inhalers |
andrenergic drug side effects related to __ incl. nervousness, tremor, dizziness | CNS |
andrenergic drug side effects related to __ incl. tachycardia, palpitations, arrhythmias, angina | heart |
andrenergic drug side effects related to __ __ incl. cardiovascular effects | vital signs |
andrenergic drug side effects related to __ __ incl. hyperglycemia | blood sugar |
route of administration for albuterol (Proventil) | MDI, inhal sol, tabs |
route of administration for epinephrine (Primatene, Adrenalin) | MDI, IM/subQ |
route of administration for terbutaline sulfate (Brethine) | SubQ, tabs |
Xanthines, dosage based on response & drug levels; IV slowly | aminophylline |
Xanthines, tabs ER | theophylline (Uniphyl) |
Xanthines, caps ER | theophylline (Theo-24) |
for increasing rate of absorption Xanthines should be taken with | full glass of water on empty stomach |
to decrease irritation caused by Xanthines | take with meals |
IM injection is contraindication for | administration of Xanthines |
side effects related to __ __ incl. nausea, vomiting, epigastric pain, abdominal cramps, anorexia, or diarrhea | GI distress |
