EXAM 3 NURS 5315 UTA(ACTUAL 2024-
2025)QUESTIONS WITH ANSWERS
pathologic hallmarks of emphysema - <<Answers>>>*
dilation of airways and the destruction of the alveolar walls
causing a decrease in a decrease in elastic recoil
* air is trapped in lungs
* the thoracic cavity changes shape (Barrel shape)
* alveolar desctruction occurs form ballue in the lung tissue
* ballue pockets air and does not assist with gas exchange
* all this causes hypoxemia, hypoventilation, and hypercapnia
* CM= pursed lipped breathing, tripod position, high
metabolic rate, thin, HYPER-RESONANT PERCUSSION
Chronic Brochitis - <<Answers>>>* productive cough fir 3
months for two consecitive years
* mucous secreting cell undergo hyperplasia and increase
mucous production
* the mucous can be hard to clear due to its viscosity and
impaired ciliary function
* hyperplasia of the cells is triggered by an irritant such as
smoking
* this usually impairs larger airwars but can eventually
involve all the airways
* airway becomes narrow and causes obstruction and air
retention
, EXAM 3 NURS 5315 UTA(ACTUAL 2024-
2025)QUESTIONS WITH ANSWERS
* the thorax expands and person becomes hypoxic,
experiences low tidal volumes, and hypoventilates
* ppl experience poor exercise tolerance, wheezing and
dyspnea
* will show obstruction on PFT and a decreases FEV1
* hypoxia causes polycythemia and cyanosis, this may lead to
pulmonary hypertension and cor pulmonale
Pneumonia - <<Answers>>>2 types= community acquired
and hospital acquired
* inmmation or process that causes a build up of inflammartor
exudate in the alveolar sacs
* can be cause by bacterial, viral, fungal, ro aspiration
* elderly have a highest mortality
* Risk Factors= advanced age, suppressed immune system,
underlying lung disease, alcohol abuse, decreased level of
consiousness, chest trauma, dysphagia, smoking, intubation,
malnutrition, immobility, cardiac and liver disease, and
residing in a nursing home
Community Acquired Pneumonia - <<Answers>>>* outside
hospital
* step pneumoniae- is the most common cause of PNA
* staph aureus- arrizes from influenza or viral pneumonia
, EXAM 3 NURS 5315 UTA(ACTUAL 2024-
2025)QUESTIONS WITH ANSWERS
* strep pyogens- from viral infection such as influenza or
measels
* Klebsiella pneumoniae- common in hospitalized debilitated
pts, diabetes, or alcoholics, high mortality rate in elderly
* haemophilus influenza- common in infants and children and
COPD adults
Hospital Acquired Pneumonia - <<Answers>>>* 48 hours
after being admitted
* common cause= gram negative bacteria such as Klebsiella
Pseudomonas aeruginosa and E-Coli.
Patho of Pneumonia - <<Answers>>>* aspiration of oral
secretions or inhalation of microorganisms from a sneeze,
cough, or a person talking
* endotrachial tubes are colonized with bacteria
* once the bacteria enters the alveolar sac, that immune and
inflammatory cascade are triggered
*CM- CAP= is acute onset and PCP present insidiously, this
is important to remember for diagnosis
- dyspnea, fever, cough, chills, malaise, pleuretic chest pain,
pulmonary rales, tactile fremitus, egophony, and whispered
pectoriloquy
Pulmonar Disease - <<Answers>>>*classified into 2 broad
categories
-restrictive vs obstructive
