NUR2063 EXAM 3 LATEST 2025 WITH CORRECT QUESTIONS AND DETAILED
ANSWERS/ALREADY GRADED A+
Homeostasis - (answer)•state of equilibrium or balance within and organism
•Fluids and electrolytes exist within the body, are dynamic in nature, and are maintained
in constant balance, or homeostasis, within the body
fluid volume deficit - (answer)•Fluid deficit occurs when total body fluid levels (mostly
water) are insufficient to meet the body's needs may also be referred to as dehydration
•Fluid volume deficits may result from vomiting and diarrhea
Fluid Volume Excess - (answer)•Daily fluid intake should equal the amount of fluid lost
•Third spacing: significant fluid increases in the transcellular compartment, which does
not exchange easily among other ECFs
Types: Edema, Water intoxication
Eukaryote - (answer)•is any cell or organism that possesses a defined nucleus
Mitochondria - (answer)•Have own DNA and ribosomes
•Produces adenosine triphosphate (ATP) for energy
what happens When arterial blood pressure decreases - (answer)•renin is released from
the kidneys and works on angiotensinogen (from the liver), converting it to angiotensin I.

ANSWERS/ALREADY GRADED A+
What is the role of renin-angiotensin-aldosterone system, antidiuretic hormone (ADH),
and natriuretic peptides - (answer)Control of fluid and electrolyte balances is maintained
The renin-angiotensin-aldosterone system (RAAS) also assist in - (answer)•maintaining
blood pressure and intravascular fluid status
What happens when renin converts angiotensinogen (from the liver), converting into
angiotensin I - (answer)•Angiotensin I is then converted to angiotensin II in the lungs by
angiotensin-converting enzymes
what is the role of Angiotensin II - (answer)•is a potent vasoconstrictor that also
stimulates the release of aldosterone
What produces Aldosterone - (answer)Hyopthalamus
What releases Aldosterone and why - (answer)The adrenal cortex releases and releases in
response to changes in blood osmolality
What is the role of Aldosterone - (answer)promotes the retention of the sodium and water
in the kidneys, restoring blood volume
directly influences water reabsorption in the distal tubules and collecting ducts in the
kidneys

ANSWERS/ALREADY GRADED A+
What may cause Fluid volume deficient - (answer)•hemorrhage, excessive loss of GI fluids
(e.g., vomiting, diarrhea).
What are the symptoms of Fluid volume deficient - (answer)thirst, weight loss, lungs clear
to auscultation, tachycardic.
What may cause fluid volume excess - (answer)•heart failure, end-stage kidney failure,
etc.
What are the symptoms of Fluid volume excess (FVE) - (answer)•crackles in the lungs,
hypertension, bounding pulses.
Where is the highest loss of daily fluids - (answer)in the urinary tract
Osmosis - (answer)•process which water travels through a selectively permeable
membrane so the concentrations of a substance that is soluble in water (solutes) are the
same on both sides of the membrane. (ex. movement of water between the interstitial and
intracellular compartments).
what type of movement is osmosis - (answer)Through osmosis water passively moves
from an area of lower particle concentration to an area of higher particle concentration.
Where does Potassium mostly exist in the body - (answer)•exists predominately in the
intracellular fluid whereas sodium and chloride exists predominately in extracellular fluid.

ANSWERS/ALREADY GRADED A+
hypokalemia - (answer)When potassium levels in the body is less than 3.5 mEq/L
hyperkalemia - (answer)When potassium levels in the body is greater than 5 mEq/L
Both hypokalemia and hyperkalemia can cause - (answer)cardiac arrhythmias
Hypocalcemia - (answer)When calcium level is below 8.5 mg/dL
Hypocalcemia can result in - (answer)•positive Chvostek's sign(contraction of the corner
of the patient's eye and mouth when the facial nerve is tapped gently and positive
Trousseau's sign (spasm of the and hand and wrist [sign of tetany]).
Hyponatremia - (answer)•<135 mEq/L
Causes from excessive sodium losses or increased water gains (dilutional hyponatremia)
Hyponatremia requires - (answer)•frequent neuro assessment due to possible fatal
cerebral edema. Due to fluid shifts in the cerebral cortex, cerebral edema and increased
intracranial pressure may develop.
Electrolyte Normal Ranges - (answer)Sodium: 136-144mEq/L
Potassium: 3.7-5.2 mEq/L
