NURS 315 CHAPTER 5 EXAM WITH ACTUAL QUESTIONS AND VERIFIED
DETAILED ANSWERS 100% PASS CONCEPTS
Crystalized intelligence - Answer Knowledge accumulated over a lifetime
Fluid Intelligence - Answer New information from non-dominant hemisphere - emotions,
creative capacities, spatial perceptions, aesthetic appreciation
Immunosenescence - Answer aging immune system
Presbycusis - Answer Progressive, irreversible hearing loss that occurs as a result of
age-related changed in the inner ear
Presbyesophagus - Answer a decreased intensity of propulsive waves and an increased
frequency of non-propulsive waves in the esophagus
Presbyopia - Answer inability to focus or accommodate properly due to reduced
elasticity of the lens that results from aging
Alterations are influenced by - Answer Genetic factors, environment, diet, health,
stress, and lifestyle choices
Changes to the body cells - Answer - cells number decrease, leaving decreased number
of functional cells
- Lean body mass decreases
- total body fat increases
, - cellular solids and bone mass decrease
- extracellular fluid remains constant
- intracellular fluid decreases, therefore decreasing total body fluid and increasing the
risk for dehydration especially in older adults
Physical appearance changes - Answer - Loss of subcutaneous fat content = loss of
insulation = intolerance to cold temperature
- graying and thinning hair
- Elongation of ears
- increased facial hair in females
- arcus senilis
- narrower pelvis in females; wider in males
- loss of height
Respiratory changes - Answer Decreased activity
Nasal --> thicker secretions and sensation of nasal stuffiness (connective tissue
relaxation - septal deviation)
Mouth: mouth breathing --> sleep apnea and OSA
