HESI LPN
The rate of change in velocity over a period of time.
Acceleration
A compound that is a hydrogen or proton donor. It is corrosive to metals, changes blue litmus paper red,
and becomes less acidic when mixed with bases.
Acids
Which is NOT true of epithelial tissue?
a) it is vascular
b) it rest on a basement membrane
c) it helps form certain glands
d) it lines cavities in the body
A) it is vascular
- Epithelial tissue is avascular, menaing it lacks bblood vessels.
Which is NOT produced by an exocrine gland?
a) milk
b) digestive enzymes
c) adrenaline
d) saliva
C) adrenaline
- Adrenaline is produced by the adrenals, which are exocrine glands
The imaginary line that separates the body into superior and inferior regions is called the ___.
Transverse plane
- the transverse (horizontal) plane separates the body into superior (upper) and inferior (lower) parts.
The sagittal, or vertical plane separates the body into left and right halves, and the coronal plane
separates the body into dorsal and ventral (back and front) sections.
The pyloric sphincter is located between ___.
The stomach and small intestine.
- the pyloric sphincter permits food to pass from the stomach to the small intestine.
Blood vessels enter and exit bones through ___.
,foramina
- Foramina are small openings in the body which allow cranial nerves, arteries, and veins to pass through
solid structures.
Which cells are responsible for bone formation?
osteoblasts
- osteoblasts are the main cells that make up bones. In organized groups, they produce a calcium and
phosphate-based mineral that helps contribute to bone strength and density.
Which one of these is a reason bones are considered to be organs?
They contain nervous and connective tissue
- Although it may not seem like it, bones are rigid organs. In order to be classified as an organ, in addition
to performing a certain function in the body, a structure must contain more than one type of tissue. So,
because bones are made of both nervous and connective tissues, they meet one of the criteria of an
organ. The other answer choices about cells and framework are true, but these are not reasons why
bones are considered an organ.
What is the correct order of the flow of waste through the large intestine?
Cecum, ascending colon, transverse colon, descending colon, sigmoid colon.
- From ingestion to excretion, the correct order that waste travels through the body is cecum, ascending
colon, transverse colon, descending colon, and sigmoid colon.
A person with AB- should NOT receive blood from which other blood type?
AB+
- Although both AB+ and AB- blood have A and B antigens, the person with AB- blood lacks a special
protein, or "Rhesus" Factor (Rh), circulating in their blood. If they are given blood that has the Rh factor
present, their body will make antibodies to this foreign substance and complication will occur. This is
especially true in pregnancy situations where the mother is Rh- and the baby she is carrying is Rh+
Which blood type is considered the universal donor?
O-
- O- blood lacks both A and B antigens and the Rh factor, making it the only blood type that can donate
to everyone.
- O- is the best donor because it does not have A, B, or Rh antigens.
- AB+ is the universal receiver because it does not have A, B, or Rh antibodies.
What us the ONLY artery in the body to carry oxygen-poor blood?
Pulmonary artery
, - Most arteries in the body carry oxygen-rich blood away from the heart, but the pulmonary artery
carries oxygen-poor blood from the right ventricle of the heart to the lungs. The vena cava would not be
correct because it is not an artery, it is a vein and the question as for artery.
Chocolate cysts of the ovaries are attributed to ___.
Endometriosis
- Endometriosis is a condition in which the tissue from the uterus (endometrium) grows in other parts of
the body, such as the ovaries or bowel. If a woman has endometrial tissue in her ovary, the tissue bleeds
and builds up over time, and as the blood ages it turns brown, hence the term "chocolate cysts".
Which is NOT true of synovial joints.
They are found in the intervertebral discs of the spinal column.
- Instead of a synovial joint, the intervertebral discs of the spinal column form a fibrocartilaginous joint,
which allows slight movement of the vertebrae of the spine.
- They have a fluid-filled capsule that surrounds their articulating surface.
- They are the most moveable joint type in the body.
- They are the most common joint in the body.
True of SYNOVIAL JOINTS
Ligaments connect ____.
bone to bone
- Ligaments connect bone to bone, and tendons connect muscle to bone.
What is the largest muscle in the human body?
Sartorius
- The longest muscle in the human body is the sartorius muscle, which is located in the anterior thigh.
Where is the hyoid bone located?
Neck
- The hyoid bone is located between the chin and thyroid cartilage
Which of these is considered the primary pacemaker of the heart?
SA node
- The sinoatrial (SA) node is located in the right atrium and is responsible for generating the electrical
impulses that cause the heart to beat.
In which location does a sperm cell first fertilize an egg?
Fallopian tube
