Study Notes

Cyanosis

Cyanosis is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood
A hemoglobin level of 15 g/dl does not show cyanosis until 5 g/dl becomes unoxygenated
Patients with anemia rarely manifest cyanosis
Patients with polycythemia, a condition with abnormally high red blood cell count, may appear cyanotic even if adequately oxygenated
Assessment of cyanosis is affected by factors like room lighting, the patient's skin color, and the distance of blood vessels from the surface of the skin
Central cyanosis, assessed by observing the color of the tongue and lips, indicates a decrease in oxygen tension in the blood
Peripheral cyanosis, caused by decreased blood flow to the body's periphery, does not necessarily indicate a central systemic problem

Chest Configuration

The normal ratio of the anteroposterior diameter to the lateral diameter of the chest is 1:2
Barrel Chest: over inflation of the lungs with an increased diameter of the thorax. It can be associated with conditions like emphysema
Funnel Chest (Pectus Excavatum): a depression in the lower portion of the sternum. It occurs with rickets or Marfan’s syndrome
Pigeon Chest (Pectus Carinatum): displacement of the sternum with an increased diameter. It occurs with rickets, or severe kyphoscoliosis
Kyphoscoliosis: elevation of the scapula and an S-shaped spine. It occurs with osteoporosis and skeletal disorders

Breathing Patterns and Respiratory Rates

Observe for the use of accessory muscles like sternocleidomastoid, scalene, and trapezius muscles during inspiration, and abdominal and internal intercostal muscles during expiration

Breath Sounds

Bronchial sounds: loud, harsh, and high-pitched, typically heard over the trachea or at the right apex
Vesicular breath sounds: soft, low-pitched, predominantly inspiratory, appreciated especially at the posterior lung bases
Bronchovesicular sounds: heard during inspiration and expiration, with a mid-range pitch and intensity
Bronchophony describes vocal resonance that is more intense and clearer than normal
Egophony describes voice sounds that are distorted

Magnetic Resonance Imaging (MRI)

Remove all metal items, including hearing aids, hair clips, and medication patches with metallic foil components
Nurses should assess for implanted metal devices before MRI
Lie flat and remain still for 30 to 90 minutes while the table moves
Loud humming or thumping noise is heard; earplugs are offered to minimize it
Communicate with MRI staff via a microphone and earphones
Patients with claustrophobia should be offered antianxiety medications

Fluoroscopic Studies

Used to assist with invasive procedures like chest needle biopsy or transbronchial biopsy, performed to identify lesions

Pulmonary Angiography

Involves the rapid injection of a radiopaque agent into the vasculature of the lungs for radiographic study of the pulmonary vessels
Obtain informed consent before angiography
Assess for known allergies to radiopaque dye
Check anticoagulation status and renal function
NPO for 6 to 8 hours
Inform the patient about warm flushing sensation or chest pain during dye injection

Radioisotope Diagnostic Procedures (Lung Scans)

Eg: Ventilation-perfusion scan

Bronchoscopy

Direct inspection and examination of the larynx, trachea, and bronchi through a bronchoscope
Informed consent needed
NPO for 4-8 hours
Preoperative medications to suppress cough reflex, sedate the patient, and relieve anxiety
Remove dentures and other oral prostheses
Usually performed under local or moderate sedation
After the procedure, the patient must not eat until cough reflex returns
Respiratory status is monitored for hypoxia, hypotension, tachycardia, dysrhythmias, hemoptysis, and dyspnea
Sedation given to patients with respiratory insufficiency may precipitate respiratory arrest

Thoracoscopy

Diagnostic procedure in which the pleural cavity is examined with an endoscope
Informed consent and NPO
Monitor vital signs, pain level, and respiratory status postoperatively
Look for signs of bleeding and infection at the incisional site

Thoracentesis

Aspiration of pleural fluid for diagnostic or therapeutic purposes

Biopsy

The excision of a small amount of tissue, may be performed to permit examination of cells from the pharynx, larynx, and nasal passages
Pleural Biopsy: Monitor for complications like shortness of breath, bleeding, or infection
Lung Biopsy: Monitor for complications like shortness of breath, bleeding, or infection
Lymph Node Biopsy

Oxygen Therapy

Oxygen is a colorless, odorless, tasteless gas that is essential for the body to function properly and to survive
Oxygen therapy is the administration of oxygen at a concentration of pressure greater than that found in the environmental atmosphere
Air that we breathe contains approximately 21% oxygen
When oxygen is used at high flow rates, it should be moistened by passing it through a humidification system to prevent it from drying the mucous membranes of the respiratory tract

Methods of Oxygen Administration

Nasal Cannula
Simple Mask
Partial Re-Breather Mask
Non-Re Breather Mask (NRBM)
Venturi Mask
Oxygen Hood
Oxygen Tent
AMBU Bag
Tracheostomy Collar
T-piece

Nasal Cannula (Pongs)

1 L/min=24%, 2 L/min =28%, 3 L/min =32%, 4 L/min =36%, 5 L/min =40%, 6 L/min=44%
Advantages: Client able to talk and eat with oxygen in place, easily used in home setting, safe and simple, easily tolerated

Simple Oxygen Mask

Delivers 35% to 60% oxygen
A flow rate of 6 to 10 liters per minute
It has vents on its sides which allow room air to leak in at many places, thereby diluting the source oxygen

Medical Management of Laryngeal Cancer

Treatment options include surgery, radiation therapy, and adjuvant chemoradiation therapy
Early-stage tumors and lesions without lymph node involvement may benefit from external-beam radiation therapy or conservation surgery
Stage III and IV tumors may require total laryngectomies with or without postoperative radiation therapy or chemotherapy

Surgical Treatment of Laryngeal Cancer

Vocal Cord Stripping, Cordectomy, Laser Surgery, Partial Laryngectomy, Total Laryngectomy

Speech Therapy

Communication includes writing, lip speaking, reading, and word boards

Deficient knowledge about the surgical procedure and postoperative course
Anxiety related to the diagnosis of cancer and impending surgery
Ineffective airway clearance related to excess mucus production secondary to surgical alterations in the airway
Impaired verbal communication related to anatomic deficit secondary to removal of the larynx and to edema
Imbalanced nutrition: less than body requirements, related to inability to ingest food secondary to swallowing difficulties
Disturbed body image and low self-esteem secondary to major neck surgery, change in appearance, and altered structure and function
Self-care deficit related to pain, weakness, fatigue, musculoskeletal impairment related to surgical procedure and postoperative course

Nursing Interventions for Laryngectomy

Providing preoperative patient education: If a complete laryngectomy is planned, the patient must understand that their natural voice will be lost. Teach coughing and deep breathing exercises, and assists with return demonstrations
Reducing anxiety: Address patient and family's fears and misconceptions, providing opportunities for open communication and discussion. Visits from previous laryngectomy patients can reassure patients about the possibility of rehabilitation
Maintaining a patent airway: Position the patient in the semi-Fowler or Fowler position post-anesthesia to promote lung expansion and decrease surgical edema. Administer IV fluids and nutrients, if necessary
Promoting Patients' Knowledge: Explain treatments in simple manner and using appropriate language
Monitoring and Preventing Potential Complications: Assess for signs and symptoms of shock, multisystem organ failure, and respiratory failure, atelectasis and pleural effusion. Assess for confusion or cognitive changes
Teaching patients self-care: Instruct patient to: Continue taking full course of antibiotics as prescribed, increase activities gradually after fever subsides, do breathing exercises, stop smoking, avoid stress, fatigue, sudden changes in temperature, and excessive alcohol intake, take influenza vaccine (pneumovax)

Pulmonary Tuberculosis (TB)

Infectious disease primarily affecting lung parenchyma, caused by Mycobacterium tuberculosis
Spreads to various body parts including meninges, kidney, bones, and lymph nodes
Infection usually occurs 2 to 10 weeks after exposure
Active disease may develop due to compromised immune system response
Global public health problem linked to poverty, malnutrition, overcrowding, substandard housing, and inadequate healthcare

TB Transmission

Spread via airborne transmission
Infected person releases droplet nuclei through talking, coughing, sneezing, laughing, or singing
Larger droplets settle, smaller remain suspended, inhaled by susceptible person

Risk Factors for TB

Close contact with someone who has active TB
Immunocompromised status
Alcoholism
People lacking adequate health care (eg, homeless or impoverished, minorities, children, and young adults)
Preexisting medical conditions, including diabetes, chronic renal failure, silicosis, and malnourishment
Immigrants from countries with a high incidence of TB (eg, (southeastern Asia, Africa, Latin America)
Institutionalization (eg, long-term care facilities, prisons)
Living in overcrowded, substandard housing
Health care workers -administration of aerosolized medications, sputum induction procedures, bronchoscopy, suctioning, coughing procedures, caring for the immunosuppressed patient, and administering anesthesia and related procedures (e.g., intubation, suctioning)
