Chapter 40: Respiratory Practice Test Flashcards
What body system controls ventilation regulation?
Central nervous system
What do these two chemicals control?
O2 transport
C02 transport
ventilation regulation
What is the purpose of the circulatory system?
Deliver oxygen
This is regulated by these four factors?
Afterload
Preload
Cardiac output (CO)
Contractility
Blood flow
These are the four most common defining characteristics of problems with what body system?
Decreased CO
Ischemia
Heart failure
Hypovolemia
Circulatory
With a patient with COPD receive oxygen via NC ?
No because their lungs work on a CO2 drive. Oxygen can cause COPD patient to stop breathing.
These four factors affect what part of the respiratory system?
Decrease in O2 carrying capacity of the red blood cell
Decreased inspired O2 concentration in the alveoli
Increased metabolic rate
Chest wall movement
Oxygenation
These four major factors affect what body system? History Risk factors Fatigue Pain
Respiratory
What are the four areas you would assess in regards to respiratory during a physical examination?
Breathing patterns
Cough
Respiratory infection
Medications
Activity intolerance Ineffective breathing pattern Ineffective airway clearance Risk for infection Impaired gas exchange Decreased cardiac output Acute pain Fatigue This is what part of the nursing process?
Diagnosis
Providing a patent airway Improving oxygenation Increasing level of independence Set priorities based on the patient’s tolerance level Collaborative care
This is what part of the nursing process?
Planning
Health promotion
Dyspnea management
Safety precautions with oxygen therapy
Mobilization of pulmonary secretions
This is what part of the nursing process?
Implementation
Common disorders of the upper and lower airway include?
Upper Airway: Viruses
Lower Airway: pneumonia, TB, Valley Fever, Aspiration, flu
This requires coordination of respiratory, cardiovascular, and hematological systems
Oxygenation
Ventilation or breathing
Alveolar-capillary gas exchange
Transporting O2 & CO2 between tissues & lungs
Moving O2 & CO2 between systemic capillaries and tissues by diffusion.
This is what process?
Oxygenation
What defense mechanisms are present in respiratory system to prevent entry of foreign bodies, irritants, microorganisms?
Cough
Cillia
This includes inspiration & expiration
Ventilation
Breathing
Adequate ventilation is dependent on?
Clear airway
Intact CNS & respiratory centers in medulla and pons of brainstem
Intact thoracic cavity which expands and contracts
Pulmonary compliance (expansion) and recoil
O2 & CO2 are exchanged through diffusion at the ______?
alveolar capillary membrane
Efficient gas exchange depends on balance between?
Ventilation (V) or air flow & Perfusion (Q) or blood flow
Blood flow to lungs may be normal, but ventilation is reduced ( VQ ratio)
What might reduce airflow, block airway?
Check Module 8 Voiceover
Areas ventilated, but not perfused (VQ ratio)
What might impair perfusion of oxygenated blood?
Check Module 8 Voiceover
This type of patients adjust to higher CO2 levels & breathing is may be controlled with hypoxic drive.
Must be kept slightly hypoxic.
Current research shows only a small % of these pts. have depressed CO2 receptors.
COPD Patient
To control ventilation Keep ____ liter flow & _______ levels as prescribed by physician .
O2
Pulse Oximeter
Receptors in coratid bodies and aortic arch respond to ___ O2 to control ventilation.
decrease
Chemoreceptors in medulla oblongata responds to _____ CO2 or ___ pH to ____ rate/depth of respirations to control ventilation.
increase
decrease
increase
6 Lifestyle Factors affecting oxygenation?
Nutrition, exercise, smoking, BP management, drug abuse, stress
3 Environmental factors affecting oxygenation?
urban pollution, occupational exposure to toxins, diseases
Four physiological factors affecting oxygenation?
Pulmonary or cardiac disease
Musculoskeletal or neuromuscular alterations affecting chest wall movement
Decreased O2 carrying capacity due to anemia or toxins (CO)
Hypovolemia due to blood or fluid loss
Developmental factors due to the aging process that affects oxygenation?
Stiffening of elastin and collagen connective tissue supporting lungs leads to chest wall stiffness.
Decreased Elastic recoil
Osteoporosis alters shape of thorax
Altered alveolar shape decreased surface area
Cilia function decreases
cough reflex
Decreased immune function. Increased risk of pneumonia, flu, TB.
This is an example of what type of body system change that could affect pulmonary function?
Cardiovascular
Does pt. c/o chest pain or difficulty breathing? Possible causes? Is airway patent?
Is skin pale, diaphoretic, dusky, or cyanotic?
This is what part of the nursing process?
Respiratory Assessment
What are VS & pulse oximetry readings?
Is the patient using accessory muscles to breathe? Such as?
This is what part of the nursing process?
Respiratory Assessment
Has the patient’s LOC changed?
Is the patient confused, anxious, or agitated?
Does the patient change position to facilitate breathing? E.g. tripod position
Are they orthopneac?
This is what part of the nursing process?
Respiratory Assessment
Chief Complaint – onset, course, duration of respiratory sx.
Current symptoms possibly R/T Respiratory problem such as?
Respiratory Assessment
Patient/Family History of Lung/Heart Problems
Asthma Emphysema Bronchitis
PE
COPD
TB
Bronchiectasis Allergy hx, exposure
Infections
Lifestyle, med use.
This is what part of the nursing process?
Respiratory Assessment
What conditions may cause this type ofpain?
Can you differentiate between cardiac, pulmonary, & muscular chest pain?
What lung conditions may cause this type of pain?
Chest Pain Assessment
Pulmonary (pleuritic) pain may be Sharp, stabbing, and intermittent May increase with breathing, coughing Dull, aching, and persistent Usually felt on affected side, may be referred May radiate to scapula.
This is what part of the nursing process?
Chest Pain Assessment
What is a cough? Dry? Productive?
Purpose of cough?
What do you want to document about a cough?
Check module 8 Respiratory Voiceover
Present and past work experiences (Why?) Smoking habits Activities of daily living tolerance Cardiac risk factors Stress level Dietary habits Relationship with significant others Recreational habits
This is what part of the nursing process?
