Question 1
Which body system is responsible for bringing oxygen into the body and expelling carbon
dioxide?
A) The circulatory system
B) The digestive system
C) The respiratory system
D) The endocrine system
E) The nervous system
Correct Answer: C) The respiratory system
Rationale: The respiratory system's primary function is gas exchange. It takes in oxygen
from the air through the lungs and removes carbon dioxide, a waste product of cellular
metabolism, from the bloodstream.
Question 2
Which body system is responsible for transporting a constant supply of nutrients and oxygen to
body cells?
A) The respiratory system
B) The cardiovascular system
C) The lymphatic system
D) The integumentary system
E) The skeletal system
Correct Answer: B) The cardiovascular system
Rationale: The cardiovascular (or circulatory) system uses the heart to pump blood through
a network of vessels. This blood carries essential oxygen and nutrients to every cell in the
body while transporting waste products to be excreted.
Question 3
A patient presents with red bumps near a previous cut. The area is swollen, painful, warm to the
touch, and full of pus. These symptoms are most closely associated with:
A) Type 1 Diabetes
B) Seasonal Influenza
C) MRSA (Methicillin-resistant Staphylococcus aureus)
D) Coronary Artery Disease
E) Autism Spectrum Disorder
Correct Answer: C) Red bumps near a previous cut that are swollen, painful, warm to touch,
and full of pus
Rationale: MRSA is a bacterial infection resistant to many antibiotics. It often appears as a
skin infection that looks like a spider bite or an infected sore, characterized by heat,
swelling, and purulent (pus) drainage.

Question 4
Which of the following is considered a controllable risk factor for Coronary Artery Disease
(CAD)?
A) Increasing age
B) Family history of heart disease
C) High cholesterol levels
D) Gender at birth
E) Ethnic background
Correct Answer: C) High cholesterol levels
Rationale: While age, genetics, and gender are non-modifiable (uncontrollable), high
cholesterol can be managed through diet, exercise, and medication, thereby reducing the
risk of plaque buildup in the arteries.
Question 5
Which recommendation aligns with the U.S. Physical Activity Guidelines for school-aged
children (ages 6-17)?
A) 150 minutes of moderate activity per week
B) 30 minutes of vigorous activity three times a week
C) 60 minutes or more of moderate to vigorous physical activity daily
D) Stretching for 10 minutes every morning
E) Walking at least 2,000 steps per day
Correct Answer: C) Complete 60 minutes or more of moderate to vigorous physical activity
daily.
Rationale: Health guidelines state that children and adolescents need significantly more
activity than adults to support healthy growth, bone density, and cardiovascular health.
The target is one hour every single day.
Question 6
Which exercise is an example of a "muscular endurance" activity?
A) A single heavy lift of a barbell
B) A 40-yard dash
C) Cycling uphill for an extended period
D) Touching your toes for 30 seconds
E) Floating in a swimming pool
Correct Answer: C) Cycling uphill
Rationale: Muscular endurance is the ability of a muscle or group of muscles to perform
repetitive contractions against resistance for an extended period. Cycling uphill requires
constant, sustained muscle exertion over time.
Question 7
To prevent fire and burns within the home, what does the CDC specifically recommend?
, 3
A) Keeping a fire extinguisher in the bedroom
B) Using only electric heaters in the bathroom
C) Maintaining home smoke alarms on every floor
D) Leaving windows open at night
E) Painting walls with fire-retardant chemicals
Correct Answer: C) Maintain home smoke alarms on every floor.
Rationale: Early detection is the most effective way to prevent fire-related deaths and
injuries. The CDC emphasizes having functional smoke alarms on every level of a
residence, especially near sleeping areas.
Question 8
What is a standard recommendation for maintaining good dental hygiene and preventing
periodontal disease?
A) Using a toothpick after every meal
B) A dental exam and professional cleaning every six months
C) Brushing your teeth once every 24 hours
D) Avoiding all crunchy vegetables
E) Replacing your toothbrush once a year
Correct Answer: B) a dental exam every six months.
Rationale: Regular professional cleanings remove tartar that brushing cannot, and exams
allow for the early detection of cavities and gum disease, which are linked to overall
systemic health.
Question 9
Which sleep stage is characterized by slow breathing and a decreasing heart rate that occurs just
before entering deeper sleep?
A) Stage 1
B) Stage 2
C) Stage 3
D) REM (Rapid Eye Movement)
E) Stage 4
Correct Answer: B) stage 2
Rationale: Stage 2 is a period of light sleep before the body enters the deep sleep stages.
During this time, the heart rate slows down, body temperature drops, and brain waves
become more rhythmic.
Question 10
Which of the following is an effective strategy for improving sleep hygiene and overall sleep
quality?
A) Exercising vigorously 30 minutes before bed
B) Checking work emails right before turning off the lights
