NURS 5315 OBESITY COMPLETE EXAM QUESTIONS WITH
CORRECT DETAILED ANSWERS GRADED A+
Which brain region is primarily involved in processing reward and pleasure related
to food intake?
A) Amygdala
B) Prefrontal cortex
C) Nucleus accumbens
D) Hippocampus - ✅✅Answer: C) Nucleus accumbens
Rationale: The nucleus accumbens is involved in the reward pathway, which can
contribute to overeating.
What is the primary factor that affects an individual's Basal Metabolic Rate
(BMR)?
A) Gender
B) Muscle mass
C) Stress levels
D) Caffeine intake - ✅✅Answer: B) Muscle mass
,Rationale: Muscle tissue requires more energy at rest, increasing BMR.
How does physical activity help prevent obesity?
A) Increases energy expenditure
B) Decreases muscle mass
C) Lowers blood pressure
D) Reduces insulin secretion - ✅✅Answer: A) Increases energy expenditure
Rationale: Physical activity helps maintain a negative energy balance by increasing
calorie burn.
What is the primary factor that leads to obesity?
A) Energy expenditure consistently exceeding energy intake
B) Balanced caloric intake and expenditure
C) Energy intake consistently exceeding energy expenditure
D) Genetic factors alone - ✅✅Answer: C) Energy intake consistently exceeding
energy expenditure
Rationale: Obesity occurs when caloric intake surpasses caloric expenditure over
time.
, Which part of the brain regulates hunger and satiety?
A) Cerebellum
B) Hypothalamus
C) Brainstem
D) Thalamus - ✅✅Answer: B) Hypothalamus
Rationale: The hypothalamus integrates hunger and satiety signals to regulate food
intake.
What type of neurons in the hypothalamus promote appetite?
A) Anorexigenic neurons
B) Orexigenic neurons
C) Dopaminergic neurons
D) Serotonergic neurons - ✅✅Answer: B) Orexigenic neurons
Rationale: Orexigenic neurons stimulate hunger and reduce metabolism.
Which hormone is known as the "hunger hormone"?
A) Leptin
