QUESTION 1
An initial disturbance in a system sets off a chain of events that
does not favor stability and often abruptly displaces a system
from its steady state. What is this called?
a. Positive Feedback
b. Negative Feedback
c. Disease
d. Homeostasis
Correct Answer: a. Positive Feedback
Rationale: Positive feedback mechanisms amplify or reinforce the
initial disturbance, moving the system further away from
homeostasis. Unlike negative feedback which works to restore
balance, positive feedback creates a cascade that can rapidly
,displace a system from its steady state. Examples include blood
clotting and childbirth.
QUESTION 2
What organ shrinks with age?
a. Prostate
b. Gums
c. Heart
d. All of the above
Correct Answer: b. Gums
Rationale: Gum tissue undergoes atrophy with age, leading to
receding gums. The prostate actually enlarges with age (benign
prostatic hypertrophy), and while the heart may change with age,
it does not typically shrink as a primary age-related change. Gums
shrink due to decreased collagen production and bone
resorption.
QUESTION 3
Which of the following is true?
, a. An infant will have a slower heart rate than an adult
b. The elderly have better temperature sensations
c. There are more sweat glands in an elderly person
d. There is less thirst perception in the elderly
Correct Answer: d. There is less thirst perception in the
elderly
Rationale: The elderly have diminished thirst perception due to
age-related changes in the hypothalamus and osmoreceptors.
This puts them at increased risk for dehydration. Infants actually
have faster heart rates than adults, temperature sensation
decreases with age, and sweat gland数量 decreases with age.
QUESTION 4
Which of the following is true?
a. Women snore more than men
b. Men have higher calcium levels
c. Women have a lower hemoglobin than men
d. Men have a lower creatinine level than women
Correct Answer: c. Women have a lower hemoglobin than
men
