This Chapter 4 exam assesses the nursing assistant's understanding of body systems and structure, observation and reporting of resident
changes, common disorders and conditions, care of the older adult, and rehabilitation and restorative principles. Each item is written at the
application and analysis level, requiring learners to apply anatomy and prioritize safe care in realistic clinical situations.

Section 1: Body Systems and Structure
1. A resident fractures a hip after a minor fall. Which change in the skeletal system of an older adult most directly
contributes to this outcome?
A. Thickening of long bones
B. Greater joint flexibility
C. Increased muscle bulk
D. Loss of bone density and calcium over time ✓ Correct Answer
Rationale: Bone density and calcium content decline with age, leaving bones brittle and more prone to fracture after
minimal trauma.
2. A resident has weakness when rising from a chair. Which muscular change of aging best explains this
difficulty?
A. Increased fast-twitch fibers
B. Loss of muscle mass and tone ✓ Correct Answer
C. Excess joint lubrication
D. Stronger tendons
Rationale: Aging reduces muscle fiber number and tone, which decreases strength and makes transfers more difficult.
3. An older adult reacts more slowly to a hot surface. Which age-related change in the nervous system explains the
delayed response?
A. Faster nerve conduction
B. Slower processing and reflex speed ✓ Correct Answer
C. Heightened pain perception
D. Increased sensory input
Rationale: Nerve conduction and brain processing slow with age, delaying reaction time and protective withdrawal from
heat.
4. A resident's pulse becomes irregular during morning care. The most likely age-related cardiovascular change
contributing to this finding is:
A. Lower resting blood pressure always
B. Wider vessel elasticity
C. Thickened, stiffer heart valves and vessels ✓ Correct Answer
D. Increased coronary blood flow
Rationale: Aging stiffens vessels and valves, which can produce irregular rhythms and reduce cardiac efficiency.
5. An older resident tires quickly during ambulation. Which respiratory change of aging explains decreased
endurance?
A. Higher oxygen saturation at rest ✓ Correct Answer
B. Increased lung elasticity
