Q

3 main parts of the skin

A

Epidermis (outer layer) - primary function is protection

Dermis (inner layer) - provide strength, support, blood and nutrients to epidermis

Subcutaneous tissue - anchor dermis, provide insulation and protection

What is the body's second compensatory mechanism for continued impairment of O2 delivery
Tachycardia - raise the heart rate
55
Respiratory acidosis
Decreased pH increased CO2

Isolation Administer medications as ordered Adequate fluid intake

57
Why should influenza cultures be obtained BEFORE administration of antivirals
To assess for the presence of bacterial infection before presence is masked by medication administration

60
Community acquired pneumonia
Occurs in individuals who have not been recently hospitalized or are living outside of health-care/long term care facilities
61
Hospital acquired pneumonia
Develops in patients after 48 hours of hospital admission
62
Health care associated pneumonia
Onset less than 48 hours after admission in those recently treated (last 30-90 days) by a healthcare agency or living in a nursing home/assisted living
63
Parenchyma
Functional lung tissue
64
Clinical manifestations of pneumonia
Fever, tachycardia, chills, pleuritic chest pain, fatigue Severe forms: purulent or blood streaked sputum, dysrhythmias
65
List 4 ways to diagnose pneumonia
1. Elevated WBC (leukocytosis) 2. ABGs typically reflect a primary respiratory acidosis with hypoxemia (elevated CO2, decreased PaO2 and decreased pH) 3. Sputum cultures 4. Imaging
66
4 ways to treat pneumonia
Oxygen Hydration Bronchodilators Antibiotics
67
Complications of pneumonia
``` Necrotizing bacterial pneumonia Pulmonary fibrosis Acute meningitis Bacteremia Atelectasis Septic shock Acute respiratory failure ```
68
What is empyema
A collection of purulent material in the pleural space | A possible complication of pneumonia
69
Pulmonary hygiene
``` Incentive spirometry Coughing and deep breathing Postural drainage Vibration/percussion Early mobility ``` Is done in an effort to mobilize respiratory secretions and allow expectoration. This reduces the incidence of atelectasis and worsening pneumonia in hospitalized patients
70
How should you position patients with pneumonia in one lung
Position the patient with the GOOD LUNG DOWN to maximize the ventilation and perfusion of functional alveolar units
71
What is activity grouping
In patients with pneumonia approach activities of care with intervals of rest. Fatigue and decreased tissue oxygen delivery limit activity tolerance

74
Induration
Is a raised, hard bump associated with a positive TB result

77
List 4 ways to identify TB as a result of the bodies inflammatory response
Unexplained weight loss, night sweats, fever and chills
78
What color sputum is best associated with presence of TB
Blood tinged or rusty colored as a result of the destruction of lung parenchyma tissue
79
Directly observed therapy
Is in place when trained health-care worker, home health-care nurse, aide or trained individual provides the prescribed TB drugs and watches the patient swallow every dose

84
What is rhinorrhea
Runny nose Associated with clinical manifestation of rhinitis
85
Diagnosis of rhinitis is based on what
History and symptoms
86
What 3 symptoms are used to diagnose acute rhinosinusitis
Purulent nasal discharge, nasal obstruction and facial pain-pressure-fullness
87
Primary lesions
May emerge as a direct result of an infectious disease process, an allergic reaction or an environmental cause Examples: birthmarks, freckles, moles, petechiae, vitiligo, warts, eczema, insect bites, blisters, herpes zoster, chicken pox, acne
88
Secondary lesions
A transformation of the primary lesion that may be caused by manual disturbance of the site that may develop secondary to itching or picking at the site Examples: excoriation, fissure, erosion, ulcer, crust, stretch marks, scars
89
Asthma
Bronchial asthma is an intermittent and reversible airflow obstruction affecting only the airways, not the alveoli
90
Short acting beta agonist
Rapid short term relief SE: tachycardia Ex: ventolin, Proventil, xopenex
