Perspective, Third Canadian Edition Test: Chapter 09 Activity Name: Chapter 09 – public health epidemiology CHN e.g., monitoring and tracking sexually transmitted infections over time – exposure-oriented epidemiology CHN e.g., studying the effects of a vegetarian diet on the health outcomes of children – disease-oriented epidemiology CHN e.g., studying the distribution of cervical cancer in social districts within a health region – occupational epidemiology CHN e.g., monitoring and tracking asbestos-related illnesses over time in a particular occupational group Learning Objective: Chapter Essay Questions Feedback: Hints: – increased the recording of death statistics CHN e.g., HHN provide information for the completion of the death certificates – used the death statistics to explain and publicize the reality of the horrid situation CHN e.g., CHNs have been very vocal in publicizing the effects and causes of homelessness – used polar diagrams to demonstrate that what was killing the soldiers was contagious diseases CHN e.g., CHNs can use Venn diagrams to illustrate the multiple host/agent/environmental factors influencing heart disease – implemented sanitation practices that proved to authorities that her ideas were correct CHN e.g., CHNs educate people about how HIV is transmitted and correct myths about how it is not transmitted Learning Objective: Chapter Essay Questions Feedback: Hints: Name: Date: Course: Stamler/Yiu: Community Health Nursing: A Canadian Perspective, Third Canadian Edition Test: Chapter 09 10 Sexually transmitted infections Health promotion – health education on human sexuality development – social marketing campaign to promote healthy sexual choices, such as condom use, abstinence, and limited sexual partners – specific protection – accessibility to free condoms and sexual health counselling Early diagnosis and prompt treatment – STI testing at easily accessible free clinics – treatment of STIs and case follow-up to treat contacts Disability limitation – testing of cure after STI treatment for high-risk persons – counselling for people with nontreatable STIs such as herpes Rehabilitation – HIV/AIDS support agencies – HIV/AIDS hospices Learning Objective: Chapter Essay Questions Feedback: Hints: Name: Date: Course: Stamler/Yiu: Community Health Nursing: A Canadian Perspective, Third Canadian Edition Test: Chapter 09 11 See Table 9.1 for more details – consistency CHN e.g., Everyone who drank the contaminated camp water got sick – strength CHN e.g., People who drank the most water got the most sick – specificity CHN e.g., Giardia parasites in the water made people sick with an enteric illness Influenza virus in the water would not make people sick with an enteric illness – time relationship CHN e.g., A person can’t get influenza until after exposure to the virus – congruence (coherence) CHN e.g., Since influenza can be transmitted through mucous membrane exposure, a person whose hands are contaminated with influenza virus and who rubs her eyes with her hands is more likely to get sick than someone does not touch her face with her hands – sensitivity CHN e.g., The greater the discrimination between those who got sick from eating raw meat and those who got sick from eating cooked meat, the greater the sensitivity to the disease being spread through raw meat – biological/medical CHN e.g., A child who plays with a child with chickenpox is more likely to get sick than one who plays with a child who is not sick – plausibility CHN e.g., Research has demonstrated that moderate exercise may be more helpful to prevent cardiac disease – experiments and research CHN e.g., Replicated studies over time add to the weight of evidence that smoking causes lung cancer – analogy factors (transfer of knowledge) CHN e.g., It is reasonable to develop a vaccine for the serotypes of HPV that cause cervical cancer, since other specific viruses have successfully been prevented through vaccination Learning Objective: Chapter Essay Questions Feedback: Hints: Name: Date: Course: Stamler/Yiu: Community Health Nursing: A Canadian Perspective, Third
