HESI (Entrance Exam) Questions and Correct
Answers
What are the most abundant elements of the human body?
✓ ~~~ Carbon, Hydrogen, Oxygen, Nitrogen
90% of the human body is composed of just four elements which are:
✓ ~~~ Carbon, Hydrogen, Oxygen, Nitrogen
The smallest unit of an element that still retains the chemical and physical properties
of the element is called:
✓ ~~~ Atom
Subatomic particles are:
✓ ~~~ Protons (positive), Neutrons (neutral) and Electrons (negative)
All matter is composed of basic substances called
✓ ~~~ Elements
An atom that tells you how many protons an atom has is called:
✓ ~~~ Atomic Number
The number of protons and neutrons is called:
, ✓ ~~~ Mass Number
What is isotope?
✓ ~~~ The same element but different number in protons and neutrons-Mass Number
(protons plus neutrons) minus Atomic Number (number of protons) equals the
number of neutrons.
What is radioactive isotope?
✓ ~~~ Atom whose nucleus undergoes degeneration and in the process gives off
radiation
What is a molecule?
✓ ~~~ Atoms bonded together to form a chemical unit
What is a compound?
✓ ~~~ Combining different atoms
What is ionic bond?
✓ ~~~ Ions with opposite charges attract
What are ions?
✓ ~~~ Particle that is electrically charged because it has gained or lost one or more
eletrons
What is a covalent bonds?
, ✓ ~~~ Atoms sharing electrons instead of losing or gain them
What is polar bond?
✓ ~~~ Bond created when electrons shared by adjacent atoms are shared unequally
hydrophilic means
✓ ~~~ water-living
Hydrophobic means
✓ ~~~ water-fearing
What is electrolyte?
✓ ~~~ Substances that release ions when puts into water
What is pH?
✓ ~~~ a measure of hydrogen ion concentration
Anterior position
✓ ~~~ a body part is located towards the front (ventral)
Posterior position
✓ ~~~ a body part is located toward the back. (dorsal)
Superior position
, ✓ ~~~ a body part is located ABOVE another part or towards the head
Anatomy
✓ ~~~ structure as well as its relationship with other structure
Physiology
✓ ~~~ function of the body
Proximal
✓ ~~~ a body part is CLOSER to a specific point of origin or attachment or closer to
the trunk of the body
Distal
✓ ~~~ a body part is FARTHER from the specific point of the origin or attachment
Superficial -external
✓ ~~~ a body part is located near the surface
Deep (internal)
✓ ~~~ a body part is located away from the surface
A sagittal plane (median) cuts the body
✓ ~~~ right down the middle
