NURS 2063 Practice Exam Questions
with Answers
Symptoms - ✔✔Subjective characteristics of disease felt only by the patient
sign - ✔✔If the doctor, nurse, or anyone notice evidence of disease such as a fever
Homeostasis - ✔✔A tendency to maintain a balanced or constant internal state; the regulation
of any aspect of body chemistry, such as blood glucose, around a particular level
Epinephrine is released during a stress response True or False - ✔✔True; Aka Adrenaline
function of mitochondria - ✔✔powerhouse of the cell, ATP production, and Production of the
cell energy.
The effective of the RAAS system -
renin-angiotensin-aldosterone system - ✔✔is essential for long-term blood pressure regulation.
It involves a complex system of hormones, proteins and enzymes.
vasodilation - ✔✔A widening and increase of the diameter of a blood vessel.
vasoconstriction - ✔✔Reduces blood flow and heat transfer by decreasing the diameter of
superficial blood vessels.
Hyperplasia - ✔✔the enlargement of an organ or tissue because of an abnormal increase in the
number of cells in the tissues.
, Apply the concept of homeostasis - ✔✔1.Stimulus produce change in variable (body
temperature falls), 2.Receptor detect change (detected by thermoreceptors in skin),
3.Information sent along Afferent pathway to control center, 4. Control centre process message
(in the thermoregulatory centre in brain).
Endoplasmic Reticulum - ✔✔an internal membrane system in which components of cell
membrane and some proteins are constructed. (Smooth & Rough ER)
Function of hormone renin - ✔✔Renin is an enzyme that helps control your blood pressure and
maintain healthy levels of sodium and potassium in your body. (When blood volume or sodium
levels in the body are low, or blood potassium is high, cells in the kidney release the enzyme,
renin. Renin converts angiotensinogen, which is produced in the liver, to the hormone
angiotensin I.)
Hydrostatic pressure capillaries - ✔✔The pressure that blood exerts in the capillaries is known
as blood pressure. The force of hydrostatic pressure means that as blood moves along the
capillary, fluid moves out through its pores and into the interstitial space.
Increased hydrostatic capillary action causes edema (T/F) - ✔✔(True) Edema- Is swelling or
excessive fluid.
include high venous pressure (e.g., heart failure, venous blockage) or excessive fluid and
sodium retention (e.g, acute renal failure).
What body functions cause fluid volume deficits? - ✔✔Blood loss from cuts/wounds Through
the gastrointestinal system: vomiting and diarrhea Abnormally excessive urination (polyuria);
can be caused by excessive intake of diuretic substances or medications or from renal disorder.
Tetany - ✔✔a symptom characterized by the involuntary contraction of muscles that leads to
painful muscle cramps, spasms of the voice box (i.e., larynx), and sensory disturbances.
What electrolyte is associated with muscular tetany? - ✔✔Hypocalcemia - aka LOW calcium
tetany (muscle twitching/spasms)
