Q

Explain the Transtheoretical Model of Health Promotion?

A

Addresses disease prevention and health promotion interventions that require a change in health-related behaviours

Contemplation: intent to change in foreseeable future. Likely to ask questions.

Preparation: ambivalence regarding unhealthy behaviour, strong desire to change to healthier habits. Change within the next month.

Action: Changes made, less than 6 months. May not see changes yet, likely to revert to unhealthy behaviours.

Maintenance: Continued over 6 months, started experiencing positive effects.

Changes to gag reflex
Less efficient
164
Changes to chest wall
Ribs and vertebrae subject to osteoporosis Costal cartilage calcifies Respiratory muscles weaken Increase dependence in accessory muscles especially diaphragm Sensitivity to intra-abdominal pressure changes
165
Changes to lungs
Decrease in size and weight and become flabbier Mucosal bed thickens Blood supply to lungs diminishes Elastic recoil diminishes -> early airway closure Age 20-30 alveoli enlarge and walls become thinner 4% loss in SA every 10 years
166
Response to Hypoxia and Hypercapnia
When mechanisms work properly the response to either is increased respiratory rate and depth This response is reduced by 40%-50% between 30 and 80
167
Risk factors that affect respiratory wellness
``` Smoking Second hand smoking Occupational exposure Environmental factors Additional Risk Factors ```
168
Nursing Assessment for respiratory function
Identifying opportunities for health promotion - Assess for risk factors - Vaccinations Detecting and preventing lower respiratory infections Physical assessment findings Promoting health for respiratory wellness - Smoking cessation - Disease prevention - Eliminate exposure to environmental pollutants Eliminating the risk from smoking
169
Prevalence of CHD
36% of men | 39% of women
170
Disease related changes in the heart
Amyloid deposits Liopofuscin accumulation Degeneration of basophils
171
Age related changes in the heart
Slight increase in left ventricular wall thickness Enlargement of left atrium Thickening of atrial endocardium Thickening of atrioventricular valves Calcification in the aortic valve Decrease in pacemaker cells and irregularity in their shape Increased deposits of fat, collagen, and elastic fibres at sinoatrial node
172
Consequences of Changes in the Heart
Changes results in: Heart less able to fully contract Longer diastolic filling and systolic emptying Myocardium more irritable and less responsive to SNS Stress adaptation less efficient
173
Changes in arteries
Tunica intima - thicken, endothelial cells become irregular, elongate Tunica media - increase in collagen, thinning and calcification of elastin (stiffening)
174
Changes in veins
Become thicker More dilated Less elastic Valves in leg veins become less efficient in returning blood
175
Consequences of Changes in Blood vessels
Arteries more vulnerable to atherosclerosis Aorta dilates to compensate for stiffness Increased peripheral resistance Slight increase in systolic BP Impaired baroreceptor function in large arteries – especially during postural changes Diminished ability to increase blood flow to vital organs Left ventricle forced to work harder Arteries stiffen and responsiveness to adrenaline stimulation diminishes -> HR fails to increase or decrease as efficiently
176
Risks for Cardiovascular Disease
``` Race Increased age Diabetes mellitus Heredity Hypertension Social Class Gender Depression Diet / nutrition Alcohol / smoking Hypertension Obesity Physical inactivity Hyperlipidemia Anxiety Stress Isolation Post menopausal ```

189
Signs used to anticipate death
