Need to know in Patient Safety | Developmental levels Mobility, sensory, and cognitive status Lifestyle choices Special risks found in health care setting |
Patient Safety according to QSEN | Minimizes risk of harm to patients and providers through both system effectiveness and individual performance. |
Patient Safety according to IOM | New standard for quality care—care that is free of unintended injury from acts of commission or omission, in any setting in which it is delivered. |
Patient Centered Care according to QSEN | Recognize the patient or designee as the source of control and full partner in providing compassionate and coordinated care based on respect for patient's preferences, values, and needs. |
Purpose of the National Patient Safety Goals (TJC website) | The NPSGs were established to help accredited organizations address specific areas of concern in regards to patient safety. |
Risks for Infant, Toddler, and Preschooler | Injuries, lead poisoning, accidents due to particular stage of growth--such as oral activity and children possibly ingesting dangerous substances or choking |
Risks for the School-Age Child | Different environments outside of the home, such as school, school transportation, after school activities, etc. Strangers, sports activities, bicycle related injuries. |
Risks for the Adolescent | greater independence and separate emotionally from family; tension associated with physical and psychological changes and peer pressures can lead to risk-taking behaviors (smoking or drugs); motor vehicle accidents |
Risks for the Adult | lifestyle habits: alcohol/drug use, and smoking; stress leading to accidents or illnesses, such as headaches, gastrointestinal disorders, and infections |
Risks for the Older Adult | physiological changes leading to greater fall risk and other types of accidents such as burns and car accidents |
Risks within the Healthcare Setting | Medical errors: infection, bed sores, and failure to diagnose and treat in time; medication errors; falls, client-inherent accident; procedure-related accidents; equipment-related accidents |
Inflammation | A protective reaction Can be caused by nonliving agents i.e. heat, trauma Always present with infection Infection occurs only through superimposed evasion of microorganisms It establishes an environment for healing |
Infection | Involves invasion of tissue or cells by microorganisms (bacteria, fungi, or viruses) Always has inflammation present Often reveals altered lab values ( i.e. WBCs, positive cultures) |
Infection and Inflammation | can be local, systemic, acute or chronic |
Recognizing Infection | Local or systemic Patient information, clinical appearance (objective and subjective) Vital signs Lab values CBC (Complete Blood Count) Culture reports |
Recognizing Inflammation | Swelling Redness --hyperemia Heat Pain/Tenderness Loss of Function |
Functions of red blood cells (erythrocytes) | carry oxygen from the lungs to body tissues and transfer carbon dioxide from the tissues to the lungs. Oxygen transfer is accomplished via the hemoglobin contained in RBC's. Hemoglobin combines readily with oxygen and carbon dioxide. |
Normal values white blood cells (leukocytes) | normally 5000 to 10,000/microliter, can rise up to 15,000 to 20,000/mm3 and higher during inflammation, high wbc count can indicate infection |
Functions of white blood cells | involved in cellular response of inflammation upon arrival at site; WBC pass through blood vessels and into the tissues; through phagocytosis, neutrophils and monocytes ingest and destroy microorganisms and other small particles |
High red blood cell count (polycethemia) | increases in the RBC count occur at high altitudes because less atmospheric weight pushes air into the lungs, causing a decrease in the partial pressure of oxygen and hypoxia. With strenuous physical training, increased muscle mass demands more oxygen. |
Normal values of red blood cells | 4-6 million/microliter |
Low red blood cell count (anemia) | can occur from either a decrease in the number of red blood cells, a decrease in the hemoglobin content, or both. Red blood cells live for approximately four months in the bloodstream |
Normal levels of platelets | 150,000-400,000/microliter |
Functions of platelets (thrombocytes) | prevent bleeding |
Chain of Infection | Infection occurs in a cycle that depends on the presence of: Infectious agent or pathogen, Reservoir or source for pathogen growth, portal of exit from the reservoir, mode of transmission, portal of entry to a host, susceptible host |
Infectious agent | microorganisms include bacteria, viruses, fungi, and protozoa; can cause disease when there is sufficient number, adequate virulence, ability to enter and survive the host, and susceptibility of the host |
Reservoir | place where a pathogen can survive but may not multiply, may be in food, oxygen, and water; factors that affect bacteria growth are temperature, pH, and light (organisms can thrive in the dark) |
Portal of Exit | for microorganisms to grow and multiply they must exit their host, portals of exits include blood, skin, and mucous membranes, respiratory tract, genitourinary tract, gastrointestinal tract, and transplacental (mother to fetus). |
Modes of Transmission | the specific way a disease is transmitted, most common: (unwashed hands) direct (person-person), physical contact, indirect (susceptible host to inanimate object), droplet (large particles that travel up to 3 ft), airborne, vehicles, vector (mosquitos) |
Portal of Entry | organism enter the body through the same routes they use for exiting |
Susceptible Host | depends on the individual degree of resistance to a pathogen (immune response). Factors that influence susceptibility are age, nutritional status, presence of chronic disease, trauma, and smoking |
pathogenicity | the ability of a pathogen to produce an infectious disease in an organism |
localized infection | localized symptoms (wound infection) pain and tenderness and redness at the wound site |
systemic infection | infection that affects the entire body instead of just a single organ or part, can become fatal if left untreated |
inflammatory response | protective reaction that serves to neutralize pathogens and repair body cells |
nursing actions that control or eliminate infections in the clinical setting | properly administering antibiotics, monitoring response to drug therapy, and using proper hand hygiene and standard precautions; supportive therapy would include proper nutrition and rest |
Role of nurse in infection control | Assess patient’s defense mechanisms (age, nutritional status, stress, disease process), susceptibility and knowledge of infections “Risk for Infection” (lab data and clinical appearance) Consult Infection Control Practitioner (clients with infection) |
Nursing Care | Handwashing Use gloves Elevate foot Aseptic technique for dressing change Discard contaminated dressing, linens, etc. properly Administer medications Management of fever Rest Maintain glucose within normal Healthy diet Teach of infection contro |
Acute/Transient Pain | protective, has an identifiable cause, is of short duration, and has limited tissue damage and emotional response |
Chronic/Persistent Pain | not protective and serves no purpose, lasts longer than anticipated, does not always have an identifiable cause, and leads to great personal suffering, can be cancerous or noncancerous) |
Chronic/Episodic | pain that occurs sporadically over an extended duration of time, may last for hours, days, or weeks (migraine headaches) |
Cancer pain | can be acute and/or chronic, sometimes nociceptive and/or neuropathic; usually due to tumor progression and its related pathological process, invasive procedures, toxicities or treatments, infection , and physical limitation--at actual site or referred |
Inferred pain by pathological process | Nociceptive pain--somatic and visceral and neuropathic pain |
Nociceptive Pain | Damage to bone, soft tissue, or internal organs Usually responsive to nonopioids and/or opioids Types of nociceptive pain: somatic pain and visceral pain |
Somatic Pain | Arises from bone, joint, muscle, skin or connective tissue Usually aching or throbbing in quality and is well localized |
Visceral Pain | Arises from viscera, such as the GI tract and pancreas Described as squeezing, cramping pain, shooting May be due to obstruction of hollow viscous, which causes the cramping and poorly localized pain |
Neuropathic Pain | Abnormal processing of sensory input by the peripheral or central nervous system Treatment usually includes adjuvant drugs A physical cause for reports of excruciating pain may not be evident on examination |
Idiopathic Pain | chronic pain in the absence of an identifiable physical or psychological cause or pain perceived as excessive for the extent of an organic pathological condition |
factors that influence pain | physiological factor (age, fatigue, genes, neurological function), social factors (attention, previous experience, family and social support), Spiritual factors, psychological factors (anxiety, coping style), Cultural Factors ( meaning of pain, ethnicity) |
Pain Assessment | Factors influencing the pain experience Location Intensity Quality Pattern Aggravating/relieving factors Medication history |
Pharmacological Measures: Nursing Responsibilities | Assess pain Determine when to administer analgesics Select the appropriate analgesic Evaluate effectiveness of the analgesics Monitor and manage medication side effects Suggest changes Consider the needs of special populations |
nursing role in pain management | Direct clinical care Patient/family teaching Education of colleagues Indentify system barriers |
Factors Affecting Oxygenation | physiological, developmental, lifestyle, environmental |
Physiological Factors affecting oxygenation*** | reduced oxygen carrying capacity, reduced inspired oxygen concentration, hypovolemia, higher metabolic rate, impaired chest wall movement-pregnancy, obesity, musculoskeletal abnormalities, trauma, neuromuscular diseases, central nervous system alterations |
Developmental Factors affecting oxygenation | infants and toddlers (upper respiratory tract infection), school age children and adolescents (smoking-respiratory infections), young and middle age adults (lifestyle factors-affect cardiopulmonary health) |
The older adult and oxygenation** | trachea & large bronchi become enlarged from calcification of the airways; alveoli enlarge, reducing the surface are available for gas exchange; the number of cilia is reduced, causing a decrease in the effectiveness of the cough mechanism-respiratory inf |
Lifestyle factors affecting oxygenation | habits such as cigarette smoking or unhealthy diets; nutrition, exercise, smoking, substance abuse, stress |
environmental factors affecting oxygenation | pulmonary disease is higher in smoggy, urban areas than in rural areas; patient's workplace --occupational pollutants include asbestos, talcum powder, dust, and airborne fibers |
Alterations in Respiratory Functioning | Atelectasis Aspiration Hyperventilation Hypoventilation Hypoxia |
Atelectasis | collapse of alveoli which prevents normal exchange of oxygen and carbon dioxide |
Aspiration | occurs when fluids are breathed into the lungs or airways leading to the lungs |
Hyperventilation | a state of ventilation in excess of that required to eliminate the carbon dioxide produced by cellular metabolism |
Hypoventilation | occurs when alveolar ventilation is inadequate to meet the body's oxygen demand or to eliminate sufficient carbon dioxide |
Hypoxia | inadequate tissue oxygenation at the cellular level, results form a deficiency in oxygen delivery or oxygen utilization at the cellular level-life threatening condition |
Signs and symptoms of Hypoxia | apprehension, inability to concentrate, declining level of consciousness, dizziness, and behavioral changes, increased pulse rate and increased rate and depth of respiration |
Cyanosis | blue discoloration of the skin and mucous membranes caused by the presence of desaturated hemoglobin in capillaries-late sign of hypoxia |
Objective nursing assessment as related to oxygenation | Inspection, Palpation, Percussion, Auscultation; Laboratory and diagnostic tests Hemoglobin Pulse oximetry Arterial blood gases |
Arterial blood gas analysis | most effective way to evaluate acid-base balance and oxygenation, deviation from normal value will indicate that the client is experiencing an acid-base imbalance; measure of: pH, PaCO2, PaO2, oxygen saturation, and HCO3- |
Inspection as related to oxygenation | Respiratory rate, rhythm, depth, breathing pattern Skin color Breathing postureMuscles used in breathing Clubbing of fingers Capillary refill Level of consciousness |
Diagnostic Tests as related to oxygenation | Hemoglobin Levels: 13.5-18g/dl males, 12-16g/dl female Chest x-ray Pulmonary function studies Lung scan Bronchoscopy Throat culture Sputum specimens |
Pulse Oximetry | Non-invasive Measures arterial oxygen saturation SpO2 Normal is > 95% Ensure accuracy: validate with patient heart rate Ensure accuracy: determine patient’s hemoglobin level Continuous, intermittent, or during ambulation |
pH | Normal arterial blood pH is 7.35 - 7.45; acidic is less than 7.35 and alkaloid is greater than 7.45 |
PaCO2 | partial pressure of carbon dioxide in arterial blood and is a reflection of pulmonary ventilation; normal range is 35 - 45 mm Hg, hyperventilation occurs when the PaCO2 is less than 35mm Hg; hypoventilation occurs when the PaCO2 level is more than 45mm Hg |
PaO2 | partial pressure of oxygen in arterial blood; normal range is 80-100mm Hg; less than 60mm Hg leads to anaerobic metabolism, resulting in acidic production and metabolic acidosis; hyperventilation also causes a decrease in PaO2, or respiratory alkalosis |
Oxygen Saturation | the point at which hemoglobin is saturated by O2, normal range is 95%-99% |
nursing action for atelectasis | hypoventilation occurs so best action is to help improve tissue oxygenation, restoring ventilatory function, treating the atelectasis, and achieving acid base balance. use of incentive spirometer, deep breathing and coughing, pursed lip breathing |
nursing action for hypoventilation | same as atelectasis, add diaphragmatic breathing-if possible, check on oxygen therapy |
nursing action for aspiration | positioning to avoid aspiration, coughing to clear sputum/fluid, maintain a clear airway |
nursing action for hyperventilation | oxygen therapy, diaphragmatic breathing to relax patient, incentive spirometer |
