Respiratory Flashcards
Define tension pneumothorax
air in the pleural space that enters the pleural space through a one way valve leading to
increased pressure on the lungs and
heart. Compressing blood vessels and
limiting venous return -> decreased CO
Symptoms of pneumothorax
Tracheal shift to unaffected side. (upper
mediastinal shift)
montelukast (singular)
used for maintaince therapy. Must be
taken once daily in the evenings.
Interventions for COPD
- provide meals after respiratory treatment.
- high calorie and high protein diet
if the tubing of a chest tube becomes disconnected what should you do?
place the tube in sterile water to prevent
pneumothorax.
thoracentesis procedure
- dawn PPE
- position client in either a lateral position on the unaffected side or leaning over the bedside table
- instruct to hold breath and remain as still as possible
- apply pressure to site after removal of needle
Normal Chest tubes
- fluctuation of drainage in the tubing with inspiration.
- little bubbling in the water seal chamber (continuous bubbling suggests air leak)
- under 100 mL of drainage per hour
- small, dark red clots
interventions for nasal cannula
assess patency of the nares, provide humidification for flow rates greater then 4L, and use a water soluble gel to prevent drying of the nares
disadvantages of face mask
if flow rate is less then 5 L/min can result in rebreathing of CO2
- cannot eat
- moisture and pressure can collect under the mask and cause skin breakdwon
nursing interventions for partial rebreather
make sure the flow rate is high enough so that the bag does not completly deflate during inspiration which causes CO2 buildup.
what are high flow oxygen delivery systems and give examples
they give precise amounts of oxygen regardless of the clients breathing pattern such as the Venturi mask, trach colar, aerosol mask
pros and cons of venturi mask
- Humidification not required therefore its good for people with chronic lung disease but its expensive
- good for avoiding oxygen induced hypoventilation which occurs in COPD patients because you can deliever precise amounts of oxygen
advantages of aerosol mask, face tent, and trach collar
fit loosly therefore good for burns or thick secretions
-have to provide alot of humidification which requires nurse to empty condensation from the tubing often.
s/s of oxygen toxicity
nonproductive cough
- substernal pain
- nasal stuffiness
- n/v
- fatigue
- headache,
- sore throat
intervention for oxygen toxicity
monitor for fatigue, restlessness, dyspnea, tachycardia/pnea, crackles, cyanosis.
-use a positive airway pressure machine to minimize the amount of oxygen needed.
why my patients recieving mechanical ventilation develop fluid retention? what should you do?
decreased cardiac output, activation of RAAS and/or ventilator humidification
Monitor I&O, weight, breath sounds and secretions
how can mechanical ventilation lead to hemodyanmic compromise
it increases the thoracic pressure leading to decreased venous return.
Monitor for tachycardia, hypotension, decreased urine, cool and clammy skin, decreased pulses, decreased LOC
what are the 4 main acute respiratory disorders
rhinitis, sinusitis, influenza, pneumonia
rhinitis
inflammation of the nasal mucosa and often the mucosa in the sinuses that can be viral or bacterial or caused by allergens. Allergens cause histamine release and other mediators which bind the blood vessels and cause leakage, leading to local edema and swelling.
expected findings in rhinitis
- runny nose(rhinorrhea) and nasal congestion
- purulent nasal discharge
- pruritus of the nose, throat, and ears
- itchy, watery eyes
- sore, dry throat
- red, inflamed, nasal mucosa
- low grade fever
interventions for rhinitis
- encourage rest
- increase fluids atleast 2000 mL
- humidifer and/or breathing steamy air
- Antihistamines (brompheniramine/psuedoephedrine)
- Leukotriene inhibitors (montelukast
- Mast cell stabilizers (cromolyn)
- all meds block the release of mediators which lead to blood vessel leakage.
- adverse effects of these medications are important, especially for older adults: vertigo, HTN, and urinary retention
more medications for rhinitis
- Decongestants (phenylephrine)-constrict blood vessels -> decrease edema
- use as prescribed to avoid rebound nasal congestion - Intranasal glucocorticoid sprays
- for prevention - antipyretics
- antibiotics
complementary therapies for rhinitis
- echinacea (herb)
- large doses of vitamin C
- zinc
assessment for sinusitis
- nasal congestion
- headache
- facial pressure which is worse when head is tilted forward
- cough
- bloody or purulent nasal drainage
interventions for sinusitis
- humidifcation
- hot and wet packs
- increase fluid intake and rest and stop smoking
- teach correct admin of nasal sprays
complications of sinusitis
Meningitis and Encephalitis
-contact providor if severe headache, neck stiffness(nuchal rigidity(cannot flex neck)) and high fever develops
