NURS 1002 Lecture 5 - The PhysicalChanges with Aging (Part II)
Lecture Objectives
• Identify normal physiological changes associating with aging

• Understand use of Registered Nurses Association of Ontario's (RNAO BPGs) to support
nursing practice, giving consideration to context
• Identify key elements of frailty and nursing assessment tools tailored for the older adult
What are some changes to skin that are associated with aging?
- skin is drier, thinner, and wrinkled
- dermis loses about 20% of thickness
- dermal blood vessels reduced
- collagen synthesis decreases
- loss of connections between epidermis and dermis (tearing/breakdown)
- less integumentary immune cells
- less activation of V D
- "sun spots" -> lentigo changes in irregular melanin production enhanced with sun exposure
- dark spots -> keratosis normal aging of keratinocyte epithelial cells (not cancer)
What are some nursing implications of skin changes associated with aging?
- vulnerable to tearing, bruising, and breakdown
- pressure ulcers
- delayed response to topically-administered toxic agents
- decreased oils/dermal lubricant
- sunlight exposure = premature age-related changes in skin
- decreased circulation = wounds are slower to heal
What are the ABCDE rules of melanoma?
Asymmetry
- one half does not match the other
Border Irregularity

What are pressure ulcer sores risk factors?
- neurological impairments (sensory info of 'pins and needles' or pain may not reach the
brain telling you to change positions)
- weight loss (bony prominences)
- friction and shearing
- immobility
- inadequate nutrition (lack of protein synthesis)
- incontinence (moisture)
- diminished sensation
- excessive body heat/sweating
- advanced age
- chronic conditions (ex. MS - decreases mobility)
Common Places:
- back of head
