NUR 2063 Essential of Pathophysiology
Exam Questions And Answers 2025 Update.
Symptoms - Answer✔Subjective characteristics of disease felt only by the patient
sign - Answer✔If the doctor, nurse, or anyone notice evidence of disease such as a fever
Homeostasis - Answer✔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 - Answer✔True; Aka Adrenaline
function of mitochondria - Answer✔powerhouse of the cell, ATP production, and Production of
the cell energy.
The effective of the RAAS system -
renin-angiotensin-aldosterone system - Answer✔is essential for long-term blood pressure
regulation. It involves a complex system of hormones, proteins and enzymes.
vasodilation - Answer✔A widening and increase of the diameter of a blood vessel.
vasoconstriction - Answer✔Reduces blood flow and heat transfer by decreasing the diameter of
superficial blood vessels.
Hyperplasia - Answer✔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 - Answer✔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 - Answer✔an internal membrane system in which components of cell
membrane and some proteins are constructed. (Smooth & Rough ER)

Function of hormone renin - Answer✔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 - Answer✔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) - Answer✔(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? - Answer✔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 - Answer✔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? - Answer✔Hypocalcemia - aka LOW
calcium
tetany (muscle twitching/spasms)
Symptoms of dehydration - Answer✔thirst, headache, fatigue, loss of appetite, dry eyes, dry
mouth, dark-colored urine
Osmosis - Answer✔Diffusion of water through a selectively permeable membrane.
Clinical manifestations of fluid excess - Answer✔peripheral edema, periorbital edema,
anasarca, cerebral edema, dyspnea, bounding pulse, tachycardia, jugular vein distension,
hypertension, polyuria, rapid weight gain, crackles, and bulging fontanelles.
2 Electrolytes that contains higher levels of extracellular fluid? - Answer✔(Sodium and
Chloride.) in biology, body fluid that is not contained in cells. It is found in blood, in lymph, in
body cavities lined with serous (moisture-exuding) membrane, in the cavities and channels of
the brain and spinal cord, and in muscular and other body tissues.
Intracellular fluid contains higher levels of which electrolyte? - Answer✔(Potassium) The fluid is
often secreted by cells to provide a constant environment for cellular operations.
