In the Hospital Case Scenario Flashcards
(57 cards)
What is normal arterial carbon dioxide tension (PaCO2)? (Potter and Perry 965)
35-45mmHG
What is normal arterial oxygen tension (PaO2)? (Potter and Perry 965)
80-100mmHG
What can cause hyperventilation? (Potter and Perry 965)
Anxiety, infections, drugs, acid-base imbalance, hypoxia, fever, chemically induced
What can cause hypoventilation? (Potter and Perry 965)
Severe atelectasis, COPD,
What is hypoxia? (Potter and Perry 965)
Inadequate tissue oxygenation at the cellular level
What can cause hypoxia? (Potter and Perry 965)
Deficiency in oxygen delivery or oxygen utilization at the cellular level, decreased hemoglobin level, diminished conc of inspired oxygen (high alt.), inability of tissues to extract oxygen from blood (cyanide poisoning), decreased diffusion of oxygen from alveoli to blood, poor tissue perfusion (shock), impaired ventilation (rib frac, chest trauma)
How is the cardiac and respiratory system different in an older patient? (Potter and Perry 966)
Development of atherosclerotic plaques in arterial system
-Osteoporosis leads to changes in size and shape of thorax
-Trachea and bronchi become enlarged
-Alveoli enlarge, decreasing SA available for gas exchange
-Functional cillia reduced, decreases effectiveness of coughing mechanisms
-Increased risk of respiratory infections
-Ventilation and transfer of respiratory gases decline due to lungs being unable to expand fully
What are signs and considerations in changes to respiratory and cardiac system of older adults? (Potter and Perry 966)
When cardiac problems become acute, they necessitate immediate hospitalization
-Existing/developing atherosclerosis or hypertension results in increased consequences in older adults
-Mental status changes (forgetfulness/irritability) are first signs of respiratory problems
-Older people may not complain about dyspnea until it affects ADLs
-Changes in cough mechanisms result in retention of pulmonary secretions, airway plugging, and atelectasis
-Age related changes to chest structure and muscle strength can affect ability to cough, increasing risk of respiratory infections
-Sedentary older adults who are immunocompromised are at greater risk of respiratory complications, should be encouraged to take influenza and pneumococcal vaccines
What are lifestyle risk factors that decrease cardiopulmonary function? (Potter and Perry 966)
Poor nutrition
-Inadequate Exercise
-Smoking
-Excessive substance use
-Stress
How can poor nutrition decrease cardiopulmonary function? (Potter and Perry 966)?
Obesity decreases lung expansion
-Increase body weight increases oxygen demands to meet metabolic needs
-Malnourished patient may experience muscle wasting, resulting in decreased muscle strength and respiratory excursion
-Reduced cough efficiency results in retention of pulmonary secretions, increases risk of infection
-High fat diets increase cholesterol and atherogensis in coronary arteries
-Obesity and malnourishment increases risk of anemia
-High carbs diets increase carbon dioxide load for patients with co2 retention
How can exercise increase cardiopulmonary function? (Potter and Perry 966)
Increases body metabolic activity and oxygen demand, which over time, increases the rate and depth of respiration
-30-60 minute exercise per day results in lower pulse and bp, lower cholesterol level, increased blood flow, and greater oxygen extraction by working muscles (good things!)
What are exercise recommendations for increasing cardiopulmonary function? (Potter and Perry 966)
-30-60 minutes exericse per day
-150 minutes moderate to vigorous activity per week
-(achievable by 10 minutes of aerobic activity at a time)
What are diet recommendations for increasing cardiopulmonary function? (Potter and Perry 967)
High # of fresh fruits, vegetables, dietary fibre, nonaminal protein, low-fat dairy products, and reduced sat fat in cholesterol
-High potassium may prevent hypertension
-Reduce intake of conc sugars (ultra-processed foods + beverages) helpful for pts with coronary heart disease
-Total intake of free sugars should not exceed 10% of total daily calorie intake
How does excessive substance use decrease cardiopulmonary function? (Potter and Perry 967)
Results in poor nutritional intake and decrease in hemoglobin production due to decreased iron intake
-Depresses respiratory center, reducing rate and depth of respiration and amount of inhaled oxygen, direct injury to lung tissues
What should be done during the nurse’s health history of a patient’s cardiopulmonary function? (Potter and Perry 968)
Pain
-Fatigue
-Smoking
-Dyspnea
-Coughing
-Wheezing
-Environmental or Geographic Exposure
-Past Respiratory Infections
-Allergies
-Health Risks/Family Health History
-Medications
How is cardiac chest pain subjectively felt in women? (Potter and Perry 968)
May be a sensation of choking, breathlessness, or pain that radiates through to back
What occurs during the physical examination of the cardiopulmonary system? (Potter and Perry 970)
Inspection
-Skin + mucous membrane colour
-General appearance
-LOC
-Adequate systemic circulation
-Breathing patterns
-Chest wall movement
-Nail Clubbing
Palpitation
-Amount+Type of thoracic excursion
-Tenderness
-Tactile fremitus
-Thrills/Heaves
-Cardiac point of maximal impulse
-Abnormal masses or lumps
-Peripheral pulses
-Edema
Percussion
-Abnormal fluid or air in lungs
-Diaphragmatic excursion
Auscultation
-Heart and lung sounds
What is generally done during the assessment phase of caring for a pt’s cardiopulmonary function? (Potter and Perry 968)
-Identify recurring and present signs and symptoms associated with the patient’s impaired oxygenation
-Ask patient about use of medication
-Determine patient’s normal and current activity status
-Determine patient’s tolerance to activity
What is generally done during the planning phase of caring for a pt’s cardiopulmonary function? (Potter and Perry 976)
-Select nursing interventions that promote optimal oxygenation in the primary care, acute care, or restorative and continuing care setting
-Consult with other health care providers as needed
-Involve pt and family in designing plan of care
Which health care professionals do nurses work with when delivery primary care of cardiopulmonary function? (Potter and Perry 976)
Physiotherapists
-Nutritionists
-Community based nurses
What are objectives, teaching strategies, and evaluation methods for a pt with cardiovascular disease? (Potter and Perry 978)
Objectives
-Patient will describe risk factors assoc with cardiovasc disease
-Patient will demonstrate health promotion behaviors
Strategies
-Explain patient about modifying risk factors
-Inform patient about other risk factors for cardiovasc disease
-Discuss patient importance of regular bp and blood cholesterol monitoring
-Educate pt on low-fat, low-salt, and calorie appropriate diets
-Educate patient about benefits of exercising 30-60 min per day to reduce weight and lower bp
Evaluation
-Patient will describe modifiable and nonmodifiable risk factors for cardiovasc disease
-Patient will verbalize strategies for balanced nutrition
-Obtain pt weight and bp
-Monitor patient serum cholesterol levels
What are various health teachings that nurses should provide to patients to increase cardiopulmonary function? (Potter and Perry 978)
Vaccinations
->Annual influenza vaccines recommended everyone +6 months
->Esp pts with chronic illnesses
-> Anyone in close contact with high risk groups
->Pneumococcal vaccine recommended for pts w/ increased risk of developing penumonia
-Healthy Lifestyle Behaviors
->Diet
->Stress

–>Walking
–>Pulse taking

Dyspnea Management
-Airway Maintenance (Humidification, Nebulization, Chest physiotherapy)
-Suctioning
-Artificial Airway
-Maintenance and Promotion of Lung Expansion
-Maintenance and Promotion of Oxygenation
-Restoration of Cardiopulmonary Functioning
How should dyspnea management be delivered as a nursing intervention to cardiopulmonary dysfunction? (Potter and Perry 980)?
Underlying process of dyspnea must be treated before using a combination of pharmacological measures, oxygen therapy, physical therapy, and psychosocial techniques
