BIO 526 Week 1 Discussion: Health and Disease

Introduction

Imagine that you are representing the staff in the health care agency where you work. In anticipation of a possible outbreak of a deadly new strain of flu, the administration has decreed that all staff must present documentation of adequate immunity against this new flu before gaining access to any patient care settings. The required flu vaccine and immunity test have only been developed and marketed in the past year.

Discussion Guidelines

Initial Post

In your initial post answer the following questions:

1. As the staff representative concerned for the rights and safety of your constituents, what questions would you raise about the accuracy of the immunity screening test?
2. Based on your general understanding of disease processes, what concerns would you have about this new flu strain in terms of its impact on staff, clients, and the agency’s readiness to handle an outbreak?

Response Post(s)

Reply to at least two classmates’ initial posts by Sunday.

Lesson 2: Effects of Aging on Health and Disease

The second concept covered this week is the physiological effects of aging. Two specific groups are examined: neonates or infants through the adolescent period, and older adults. The extensive list of learning outcomes is covered in the presented materials.

Learning Outcomes

At the end of this lesson, you will be able to:

Concepts of Altered Health in Children

• Growth and DevelopmentCharacterize the use of percentiles to describe growth and development during infancy and childhood
• Describe the major events that occur during prenatal development from fertilization to birth
• Define the terms low birth weight, small for gestational age, and large for gestational age
• InfancyExplain how the common health care needs of the premature infant differ from the health care needs of the term newborn or infant
• Early ChildhoodDiscuss the common health problems of early childhood
• Middle to Late ChildhoodCharacterize the growth and development that occurs during the early school years
• Discuss the common health problems of middle to late childhood
• AdolescenceCharacterize the physical and psychosocial changes that occur during adolescence

Concepts of Altered Health in Older Adults

• The Older Adult and Theories of AgingDefine young-old, middle-old, and old-old and characterize the changing trend in the older adult population
• Discuss theories of biologic aging
• Physiologic Effects of AgingDescribe the process of bone loss that occurs with aging
• Identify the common changes in blood pressure regulation that occur with aging
• Describe changes that occur in the gastrointestinal tract with aging
• Explain the significance of decreased lean body mass on interpretation of the glomerular filtration rate (GFR) using serum creatinine levels
• Functional Problems Associated with AgingList five symptoms of depression in older adults
• Name a tool that can be used for assessing cognitive function
• Explain the difference between delirium and dementia
• Drug Therapy in the Older AdultList five factors that contribute to adverse drug reactions in the older adult
