A nurse is teaching a client about states of matter. Which statement by the client
indicates correct understanding of a gas?
a. "Particles are tightly packed and vibrate in place."
b. "Particles have no mass and no energy."
c. "Particles move freely and fill the container."
d. "Particles are fixed in a rigid structure."
✔️ Correct Answer: c. "Particles move freely and fill the container."
Rationale:
Gas particles have high kinetic energy, are widely spaced, and move freely, allowing them
to fill any container. Solids have tightly packed particles, while liquids have intermediate
movement. NCLEX focus: Matter and States of Matter.
A student is comparing physical and chemical changes. Which example represents a
chemical change?
,a. Melting ice
b. Breaking glass
c. Rusting iron
d. Dissolving sugar in water
✔️ Correct Answer: c. Rusting iron
Rationale:
Rusting iron forms iron oxide, a new substance, indicating a chemical change. The other
options are physical changes because no new substance is formed. NCLEX focus: Physical
vs Chemical Changes.
A nurse explains energy transfer. Which process best demonstrates conduction?
a. Heat rising from a radiator
b. Warm air circulating in a room
c. Heat moving through a metal spoon
d. Energy transfer through sunlight
✔️ Correct Answer: c. Heat moving through a metal spoon
Rationale:
Conduction is heat transfer through direct contact, especially in solids like metals. The
other options describe convection or radiation. NCLEX focus: Heat Transfer Mechanisms.
Which scenario best demonstrates Newton's First Law of Motion?
a. A car accelerating when gas is applied
b. A ball rolling until friction stops it
c. A rocket launching into space
d. A force causing a change in direction
✔️ Correct Answer: b. A ball rolling until friction stops it
Rationale:
Newton's First Law states that an object in motion stays in motion unless acted upon by
an external force. Friction eventually stops the ball. NCLEX focus: Newton's Laws of
Motion.
,A nurse is reviewing chemical reactions. Which is a characteristic of an exothermic
reaction?
a. It absorbs heat from surroundings
b. It releases heat to surroundings
c. It stops all particle motion
d. It requires no energy input
✔️ Correct Answer: b. It releases heat to surroundings
Rationale:
Exothermic reactions release energy, usually as heat. Endothermic reactions absorb
energy. NCLEX focus: Thermochemical Reactions.
Which layer of Earth is primarily responsible for generating the magnetic field?
a. Crust
b. Mantle
c. Outer core
d. Inner core
✔️ Correct Answer: c. Outer core
Rationale:
The liquid iron in the outer core generates Earth's magnetic field through convection and
motion of conductive material. NCLEX focus: Earth's Interior Structure.
A student observes water boiling. What phase change is occurring?
a. Condensation
b. Melting
c. Vaporization
d. Sublimation
, ✔️ Correct Answer: c. Vaporization
Rationale:
Boiling is a form of vaporization where liquid changes to gas due to heat energy. NCLEX
focus: Phase Changes of Matter.
Which organelle is responsible for energy production in a cell?
a. Nucleus
b. Ribosome
c. Mitochondria
d. Golgi apparatus
✔️ Correct Answer: c. Mitochondria
Rationale:
Mitochondria produce ATP through cellular respiration, supplying energy for cellular
activities. NCLEX focus: Cell Structure and Function.
A nurse explains ecosystems. Which is an example of a biotic factor?
a. Sunlight
b. Water
c. Temperature
d. Plants
✔️ Correct Answer: d. Plants
Rationale:
Biotic factors are living components of an ecosystem, such as plants and animals. NCLEX
focus: Ecology Basics.
Which process is responsible for removing waste from a cell?
