Section 1: Anatomy, Physiology, and Terminology
1. Which body system is primarily responsible for the transport of
nutrients, gases, and waste products?
A) Respiratory
B) Digestive
C) Circulatory
D) Lymphatic
Answer: C
Rationale: The circulatory system, including the heart and blood
vessels, acts as the body's primary transportation network.
2. The term "distal" refers to a structure that is:
A) Closer to the point of attachment.
B) Further from the point of attachment.
C) Towards the midline of the body.
D) Away from the midline of the body.
Answer: B
Rationale: In medical terminology, distal describes a position
farther from the center of the body or a point of attachment.
3. Which organ is the primary site for gas exchange in the human
body?
A) Heart
B) Trachea
C) Lungs
D) Liver
Answer: C
Rationale: The lungs contain alveoli where oxygen is absorbed
and carbon dioxide is released.
, 4. A patient experiencing "tachycardia" has:
A) High blood pressure.
B) Low blood sugar.
C) A rapid heart rate.
D) A slow respiratory rate.
Answer: C
Rationale: "Tachy-" means fast and "-cardia" refers to the heart.
5. The central nervous system (CNS) consists of the:
A) Brain and spinal cord.
B) Cranial nerves and spinal nerves.
C) Heart and lungs.
D) Sensory and motor neurons.
Answer: A
Rationale: The brain and spinal cord form the CNS, while the
nerves branching off form the peripheral nervous system.
Section 2: Fundamentals of Electricity and Electronics
6. According to Ohm's Law, if voltage remains constant and
resistance increases, what happens to the current?
A) Increases
B) Decreases
C) Remains the same
D) Becomes zero
Answer: B
Rationale: Ohm's Law (
) dictates that current (
) is inversely proportional to resistance (
).
7. Which electronic component is used to store an electrical charge?
A) Resistor
B) Inductor
,C) Capacitor
D) Diode
Answer: C
Rationale: Capacitors store energy in an electric field.
8. A multimeter set to measure "Continuity" is checking for:
A) Total voltage.
B) A complete path for current flow.
C) The presence of a magnetic field.
D) Battery life.
Answer: B
Rationale: Continuity testing ensures there is a low-resistance path
between two points in a circuit.
9. Which component allows current to flow in only one direction?
A) Transistor
B) Transformer
C) Diode
D) Potentiometer
Answer: C
Rationale: Diodes act as one-way valves for electrical current.
10. In a series circuit, if one light bulb burns out, the other bulbs in the
circuit will:
A) Stay lit.
B) Get brighter.
C) Go out.
D) Flicker.
Answer: C
Rationale: A series circuit provides only one path; an open at any point
stops current flow to all components.
Section 3: Healthcare Information Technology (IT)
11. What does the acronym HIPAA stand for?

medical device integration?
A) 802.11 (Wi-Fi)
B) 10BaseT
C) RS-232
D) USB 3.0
Answer: A
Rationale: Most modern mobile medical devices use Wi-Fi standards
for data transmission to Electronic Medical Records (EMR).

A) Updating antivirus software.
B) A fraudulent attempt to obtain sensitive information by disguised
electronic communication.
C) Connecting a device to a hospital network for the first time.
D) Troubleshooting a printer.
Answer: B
Rationale: Phishing is a significant cybersecurity threat in healthcare
IT.
