NFDN 1002-Unit 6 Oxygenation 2024/2025 Actual Exams

Questions with 100% Correct Verified Answers Graded A

What assessment techniques are required to assess oxygen needs of a client? Health history, physical examination (inspection, palpation, percussion and auscultation), vital signs (resps and O2 sats) What are physiological factors that can impact a client's oxygen status?

  • Hypoxia
  • Cardiomyopathic condition
  • Peripheral Tissue
  • Respiratory disorders including hyperventilation
  • Anemia What conditions can affect chest wall movement?
  • Pregnancy
  • Obesity
  • Musculoskeletal abnormalities
  • Trauma
  • Neuromuscular diseases
  • CNS alterations
  • Influences of chronic disease What lifestyle factors can influence oxygenation?
  • Nutrition and obesity
  • Inadequate exercise (rate and depth respirations decrease)
  • Smoking and substance abuse (associated with cOPD, lung cancer)
  • STRESS AND ANXIETY (great we're all dead) arterial blood gases (ABGs)

needle in artery-a test performed on arterial blood to determine levels of oxygen, carbon dioxide, and other gases present A pulmonary angiography -- looks at blood vessels in the lungs for blood clots that could end up going to the brain What is a scope of the bronchi called? bronchoscopy Why would a sputum culture be obtained? Tuberculosis What age-related changes might be seen in the respiratory system?

  • Alterations in the thorax that occur from ossification of costal cartilage, decreased space between vertebrae, and diminished respiratory muscle strength lead to impairment of chest expansion and oxygenation
  • Cough mechanism changes can lead to retention of pulmonary secretions, airway plugging and atelectasis if cough suppressants are not used with caution Which skin test is unreliable in older adults? the tuberculin skin test - frequently displays false-positive and negative skin tests Why are respiratory infections more common in elderly people? changes in immune function lead to a decrease in cell-mediated and humoral immunity making them at increased risk What pharmacological treatments can maintain and improve a client's oxygenation status? bronchodilators, steroids, mucolytics and low-dose anti-anxiety medications Types of oxygen therapy to reduce dyspnea
  • Cardiopulmonary Reconditioning through exercise
  • Breathing techniques
  • Cough control
  • Relaxation techniques
  • Biofeedback
  • Meditation Examples of airway maintenance that mobilize pulmonary secretions
  • Humidification
  • Nebulization
  • Chest physiotherapy
  • Postural Drainage (use of positioning to draw secretions from specific segments of the lungs and bronchi into the trachea) When is oropharyngeal or nasopharyngeal suctioning used? When patient is able to cough effectively but unable to clear secretions by expectorating or swallowing When is orotracheal or nasotracheal suctioning required? Necessary when a patient with pulmonary secretions is unable to manage secretions by coughing and does not have an artificial airway Why is the nose route preferred over oral route when suctioning? Stimulation of gag reflex is minimal How long should suctioning be performed for? 10 seconds How is tracheal suctioning accomplished? Through an artificial airway such as an endotracheal tube or tracheostomy tube How big should a suction catheter be? one-half the size of the internal diameter of the artificial airway To avoid trauma to the mucosa of the lung when suctioning, what measures should be taken? Never apply suction pressure while inserting the catheter and maintain suction pressure less than 150 mm Hg in adults. Apply suction intermittently Open suctioning involves a ----catheter

sterile catheter that is opened at the time of suctioning Closed suctioning involves what type of catheter? a multiple-use suction catheter encased in a plastic sheath. When is closed suctioning most often used? On patients who require mechanical ventilation to support their respiratory efforts as it permits continuous delivery of oxygen while suction is performed Types of artificial airways Oral/Endotracheal and tracheal Presence of an artificial airway places a patient at high risk for what? infection and airway injury What aids in the promotion and maintenance of lung expansion? ambulation, positioning, incentive spirometry and chest tubes Name the methods of oxygen delivery nasal cannula, low/high flow devices, oxygen masks (simple, partial rebreathing and venturi masks) Important teachings for patients on oxygen O2 is highly combustible, no smoking, avoid open flames and no electrical shavers! Also no vaseline What position is best for clients to promote airway clearance? 45 - 90 degree elevation - high fowler's position Describe deep breathing techniques With patient in High Fowlers position, instruct them to place hand over abdomen and take slow deep breaths through the nose and push abdomen against their hand. Inform the patient they will feel middle fingers separate during inhalation how does deep breathing promote airway clearance? opens air passages and increases lung volume

How does coughing promote airway clearance? Mobilizes secretions decreasing the risk for pneumonia, clears airway and promotes lung expansion and gas exchange What is the purpose of pursed lip breathing? Deep inspiration and prolonged expiration - prevents alveolar collapse and increases arterial O saturation What is the purpose of incentive spirometry? Promotes deep breathing to prevent or treat atelectasis, promotes lung expansion and prevents pulmonary complications Describe the process of using an MDI

  1. shake inhaler vigorously 5-6 times
  2. Client exhale
  3. Mouth around mouthpiece - avoid exhalation slots
  4. Advise to inhale deeply and slowly through the mouth 3-5 seconds
  5. Hold breath for 10 seconds
  6. Wait 20-30 seconds in between inhalations
