Med Surg Test 1 part 1 Flashcards
Cxr
Chest x ray
Peak flow meter measures
lung capacity
V/q scan
nuclear medicine scan that uses radioactive material (radiopharmaceutical) to examine airflow (ventilation) and blood flow (perfusion) in the lungs.
purpose of V/Q scan
look for pulmonary embolism (PE)
gallium scan
look for swelling (inflammation), infection, or cancer in the body. It uses a radioactive material called gallium and is a type of nuclear medicine exam.
before an ABG test,
check that platelet levels are norma
do an Allen test
Hypoventilation assessment findings
Diminished breath sounds,
decreased respiratory effort,
use of accessory muscles
Hypoventilation interventions
Position q2h to promote ventilation/perfusion matching,
encourage slow deep breaths
Impaired Gas Exchange interventions
evaluate ABG
suction as indicated
Not positioning
the best way to determine need for O2 therapy
ABG
CO2 narcosis
loss of sensitivity to high levels of CO2
If a large volume of nitrogen in the lungs is replaced with oxygen, the oxygen may subsequently be absorbed into the blood, reducing the volume of the alveoli, resulting in
Absorption atelectasis
Tracheostomy indications
Long term airway management Upper airway obstruction Upper airway bleeding Inability to clear lower airway secretions Long term mechanical ventilation Sleep apnea Laryngeal or tracheal fracture Airway burns
oral care: Avoid glycerin swabs or mouthwash containing
alcohol
Weaning from a Tracheostomy Tube: gradually decrease
tube size
Weaning from a Tracheostomy Tube: cuff is deflated when patient can manage
secretions
patient that can NEVER be intubated
laryngectomy
pink puffer
emphysema
emphysema sputum
minimal
chronic bronchitis sputum
excessive
cor pulmonale is common in which COPD
chronic bronchitis
Cor pulmonale
hypertrophy of right side of the heart with or without heart failure resulting from pulmonary hypertension
In copd, pulmonary htn is caused by constriction of the
pulmonary vessels in response to alveolar hypoxia with acidosis further potentating the vasoconstriction.
Goal for copd pt: eats over
50% of diet
2 very important questions to ask an asthma pt
have you ever taken steroids
ever been intubated because of asthma
Peak expiratory flow rate
a person’s maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person’s ability to breathe out air
incentive spirometer
used to help patients improve the functioning of their lungs
ipratropium
Cholinergic antagonists
montelukast
Leukotriene antagonists
Immunomodulators
cromolyn
Stepwise approach for managing asthma: quick relief
short acting bronchodilator, up to 3 treatments at 20 minute intervals
course of systemic corticosteriods
Stepwise approach for managing asthma: step 2
symptoms 80%
Low dose inhaled steroids,
cromylyn,
leukotriene modifier,
course of systemic steroids
Stepwise approach for managing asthma: step 3
-daily symptoms with pef >60
low to medium dose inhaled steriods,
theophylline,
leukotriene modifier
Stepwise approach for managing asthma: step 4
symptoms or continual or frequent at night, pef
high dose inhaled steroids, steroids, long acting inhaled b agonists
status asthmaticus
Severe, life-threatening, acute episode of airway obstruction
Intensifies once it begins, often does not respond to common therapy
status asthmaticus Treatment
IV fluids,
potent systemic bronchodilator,
steroids,
epinephrine,
helpful eating pattern for someone with lower resp problem
4 to 6 smaller meals a day
An accumulation of fluid within the intrapleural space that may reflect and increase in pleural fluid formation or a decrease in its reabsorbtion from the intrapleural space or both
Pleural effusion
An inflammation of the lung parenchyma usually associated with a marked increase in interstitial and alveolar fluid
Pneumonia
Pneumonia: the breath sounds over the area of consolidation will be
bronchial breath sounds
common adventitious sounds with pneumonia
Wheezing, rhonchi, crackles
Pleurisy
inflammation of the pleura
Virchow’s triad
Venous stasis
Endothelial injury
Hypercoagulable state
Pulmonary embolism symptoms
chest pain
Fast/irregular HR
Light headed
Fast breathing
Acute Respiratory Failure: ABG value: Pao2
less than 60
Acute Respiratory Failure: ABG value: Sao2
less than 90
Acute Respiratory Failure: ABG value: Paco2
greater than 50
Acute Respiratory Failure: ABG value: pH
less than 7.30
Raynaud’s Disease
some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress. In Raynaud’s disease, smaller arteries that supply blood to your skin narrow, limiting blood circulation to affected areas
