1. What is the primary function of the respiratory system?
A) Circulation of blood
B) Exchange of gases
C) Digestion of food
D) Filtration of lymph
Answer: B
Explanation: The primary function of the respiratory system is to
facilitate the exchange of oxygen and carbon dioxide between the
external environment and the body's cells. This process, known as
respiration, is essential for cellular metabolism and acid-base balance.
2. Which chamber of the heart pumps deoxygenated blood to the
lungs?
A) Left atrium
B) Right atrium
C) Left ventricle
,2|Page
D) Right ventricle
Answer: D
Explanation: The right ventricle receives deoxygenated blood from the
right atrium and contracts, sending it through the pulmonary artery to
the lungs for gas exchange. The left ventricle pumps oxygenated blood
to the systemic circulation.
3. The axial skeleton is composed of the:
A) Upper and lower extremities
B) Skull, vertebral column, and rib cage
C) Pectoral and pelvic girdles
D) Bones of the hands and feet
Answer: B
Explanation: The axial skeleton forms the central axis of the body and
includes the skull, vertebral column, and thoracic cage. It protects the
brain, spinal cord, and thoracic organs, while the appendicular skeleton
comprises the limbs and girdles.
4. What is the normal resting respiratory rate for an adult?
A) 8-10 breaths per minute
B) 12-20 breaths per minute
C) 22-30 breaths per minute
D) 30-40 breaths per minute
Answer: B
,3|Page
Explanation: A normal adult at rest typically breathes 12 to 20 times per
minute. Rates below 12 indicate bradypnea, and rates above 20 suggest
tachypnea, both of which may be signs of underlying pathology.
5. Which of the following is a sign of inadequate breathing?
A) Bilateral chest expansion
B) Use of accessory muscles
C) Regular rhythm
D) Pink, warm skin
Answer: B
Explanation: Accessory muscle use, such as the sternocleidomastoid
and intercostal muscles, indicates increased work of breathing and
respiratory distress. Adequate breathing is characterized by clear
breath sounds, regular rhythm, and normal skin color.
6. The primary muscle of respiration is the:
A) Sternocleidomastoid
B) Pectoralis major
C) Diaphragm
D) Trapezius
Answer: C
Explanation: The diaphragm is a dome-shaped muscle separating the
thoracic and abdominal cavities. Its contraction creates negative

intrathoracic pressure, drawing air into the lungs, and is responsible for
approximately 70% of tidal volume at rest.
7. An adult patient has a heart rate of 110 beats per minute. This is
described as:
A) Bradycardia
B) Normal sinus rhythm
C) Tachycardia
D) Asystole
Answer: C
Explanation: Tachycardia in an adult is generally defined as a heart rate
exceeding 100 beats per minute. Bradycardia is a heart rate below 60
bpm. A rate of 110 bpm may be a compensatory response to stress,
hypovolemia, or fever.
8. The layer of skin containing blood vessels, nerves, and hair follicles is
the:
A) Epidermis
B) Subcutaneous layer
C) Dermis
D) Fascia
Answer: C
Explanation: The dermis lies beneath the epidermis and contains the
vascular network, sensory nerve endings, sweat glands, and hair
