Q1
A patient has increased heart rate and sweating during stress. This response is controlled
primarily by:
A. Parasympathetic nervous system
B. Somatic nervous system
C. Sympathetic nervous system
D. Endocrine system only
Answer: C
Rationale: Fight-or-flight is mediated by the sympathetic nervous system.
Q2
Which situation best demonstrates negative feedback?
A. Child growth spurt
B. Blood glucose returning to normal after insulin release
C. Labor contractions increasing
D. Blood clot formation
Answer: B
Rationale: Negative feedback restores balance.
Q3
A patient has damage to the cerebellum. Which finding is expected?
,A. Memory loss
B. Loss of balance and coordination
C. Paralysis of breathing
D. Loss of vision
Answer: B
Rationale: Cerebellum controls coordination.
Q4
Which electrolyte imbalance most directly affects cardiac rhythm?
A. Sodium
B. Calcium
C. Potassium
D. Chloride
Answer: C
Rationale: Potassium is critical for cardiac electrical activity.
Q5
A drug blocks ribosomes. What is the primary effect?
A. No ATP production
B. No protein synthesis
C. No DNA replication
D. No lipid formation
Answer: B
Rationale: Ribosomes make proteins.
Q6
Which structure prevents food from entering the airway?
A. Diaphragm
B. Epiglottis
, C. Trachea
D. Bronchi
Answer: B
Rationale: Epiglottis closes during swallowing.
Q7
A patient has low hemoglobin. The main expected symptom is:
A. High blood pressure
B. Low oxygen delivery
C. Increased digestion
D. Muscle hypertrophy
Answer: B
Rationale: Hemoglobin carries oxygen.
Q8
Which hormone increases blood glucose levels?
A. Insulin
B. Glucagon
C. Estrogen
D. Melatonin
Answer: B
Rationale: Glucagon raises blood glucose.
Q9
Which kidney structure is responsible for filtration?
A. Loop of Henle
B. Glomerulus
C. Ureter
D. Bladder
