Q

what is xerostomia

A

when salivary glands are in the path of treatment (radiation)
causes permanent dry mouth

22
Q

what does xerostomia increase risk in pt for

A
  • dental cavities (saliva is a natural protectant)
  • oral infections
  • halitosis (bad breath)
  • change in taste buds-nutrition help
  • difficulty swallowing
23
Q

what helps with xerostomia

A

mouth swabs, sprays, artificial saliva

increase fluid intake

24
Q

radiation and chemo cause what is laryngeal cancer pt

A

mouth sores

25
what is surgical management of laryngeal cancer determined by
size, location, and degree of cancer
26
what are the types of surgery for laryngeal cancer
laser laryngoscopy laryngectomy radical neck dissection neck dissection (removal of neck muscles/lymph nodes)
27
what is the normal flow of air when we talk
trachea, larynx, mouth, formation of words
28
what is a laryngectomy
complete removal of larynx
29
how is the trachea adjusted in laryngectomy
- rerouted through neck - no more connection to mouth, no words out of mouth - can still eat, esophagus not altered
30
what is the biggest concern with laryngectomy
communication (need to re teach how to talk)
31
what is nursing priority with laryngectomy pt
airway management
32
why do laryngectomy pts have drain
to collect blood from site and ensure patent airway
33
why can aspiration not occur in laryngectomy pt
trachea completely separated from esophagus (trach rerouted to neck)
34
what type of management is necessary post laryngectomy
- pain management (PCA)- very uncomfortable - before initiating eating, Barium swallow - speech rehabilitation
35
describe the types of speech rehabilitation
- electrolarynges-easiest to use (robot voice) - esophageal speech-burp air up to form words (air from esophagus) - tracheoesophageal puncture- one way valve to make sound (most normal voice) * not everyone is a candidate for this
36
post op care of laryngectomy
- trach care, sterile technique with suctioning - cough secretions up - do not suction unless sats drop - change inner cannula each shift - maintain fluid intake - may choke when swallow-relearn by head forward and food at back
37
broadly describe what asthma is
- immune response gone wrong (overboard reaction to normal response) - reversible airflow obstruction and wheezing - intermittent occcurence
38
describe bronchiole during asthma attack
Normal bonchiole: wide open lumen (easy for air to pass through) asthmatic bronchiole: very small lumen (difficult for air to pass through)
39
patho of asthma attack
1) trigger (ie dust) 2) IgE pick up trigger and carry to mast cells 3) mast cell releases excessive histamine response
40
what are the arterial CO2 levels early and late in asthma attack
early: decreased CO2 late: increased CO2
41
how is asthma classified
based on response to asthma drugs
42
s/s of asthma attack
cough, increased mucus, SOB, chest tightness, wheezing and prolonged expiration, retractions
43
when is asthma attack an emergency
if symptoms do not respond to usual treatment in 30 min, seek medical attention
44
what are indicators of hypoxemia
tachycardia, increased restlessness, tachypena
45
potential triggers of asthma attack
hypersensitivity, URI, exercise, air pollutants
46
how is asthma diagnosed
pulmonary function test and peak expiratory flow rates
47
describe pulmonary function test (PFT)
looking for reversibility of airway obstruction | *hallmark of asthma
48
describe peak expiratory flow rates
most valuable in determining severity and effectiveness of treatment how well are they moving air in and out?
49
what is a firm diagnosis of asthma
20% less than what is normal (PEFR) OR increased by greater than 12% after rescue drug
50
what is the management of asthma
A-adrenergics (beta 2 agonists and Albuterol) S-steroids (inhaled) T-theophylline (when not responsive to meds) H-hydration (IV with severe distress) M-maintain patent O2 sat (>90) A-anticholinergics
51
what is important education for pt taking corticosteroids
rinse mouth out after inhaled corticosteroids to prevent thrush
