UNAR Body Systems, Aging and Common Conditions

Question 1

Which organ system is responsible for moving blood throughout the body?

Accepted Answer

Circulatory (cardiovascular) system

Answer

The heart, blood vessels and blood make up the circulatory system, which delivers oxygen and nutrients to tissues.

Question 2

Which change is a normal part of the aging process?

Accepted Answer

Thinning, drier skin

Answer

Aging skin becomes thinner, drier and more fragile. Sudden confusion, chest pain or complete sensory loss are not normal aging changes and must be reported.

Question 3

A resident with diabetes becomes sweaty, shaky and confused. What should the nursing assistant do?

Accepted Answer

Report immediately to the nurse because it could be low blood sugar

Answer

These are signs of hypoglycemia (low blood sugar), which can become an emergency. Report immediately. Nursing assistants do not give insulin or other medications.

Question 4

Which are signs and symptoms of a stroke that should be reported immediately?

Accepted Answer

Sudden weakness on one side of the body, facial drooping or slurred speech

Answer

Sudden one-sided weakness, facial droop, speech difficulty or confusion are classic stroke signs. Immediate medical attention matters, so notify the nurse right away.

Question 5

A resident with congestive heart failure (CHF) has gained 3 pounds overnight and has swollen ankles. What should you do?

Accepted Answer

Report this to the nurse because it may indicate fluid retention

Answer

Rapid weight gain and swelling (edema) may indicate fluid buildup from worsening heart failure. Accurate weights and prompt reporting help the team adjust treatment.
