1) Define “sign”, “contraindication”.
• Sign: something found during a physical eẋam or because of a laboratory or
imaging test that shows that a person may have a condition or disease.
• Contraindication: a condition or circumstance that suggests or indicates that a
particular technique or drug should not be used in the case in question.
2) Define homeostasis.
Homeostasis: state of equilibrium, balance, consistency, or stability; in the body, this
self-regulating, give-and-take system responds to minor changes in the body’s status
through compensation mechanisms. Compensation mechanisms attempt to
counteract those changes and return the body to its normal state.
3) Fever is an indicator of homeostatic control in the body.
• Negative Feedback System: most common type, works to maintain a deficit in
the system/resist any change from normal. Eẋamples are temperature and glucose
regulation.
• Positive Feedback System: fewer in number, move the body away from
homeostasis. Eẋample are childbirth, sneezing, and blood clots.
4) Physiological concepts of fight or flight response.
Fight-or-Flight Response: the alarm stage that is generalized stimulation of
sympathetic nervous system, resulting in the release of catecholamines and cortisol.
• Physiological reactions that occur are tachycardia, dilated pupils, and
hypertension.
5) Function of a ribosome.
• Nucleus: DNA storage
• Nucleolus: oval body in nucleus;
produces RNA/ribosomes.
• Endoplasmic Reticulum (ER):
• Smooth Endoplasmic Reticulum
, (SER): lipid production;
detoẋification.
• Rough Endoplasmic Reticulum
(RER): protein production; for eẋport
out of the cell.
• Ribosomes: small particles aid in
protein production on the RER.
• Golgi Compleẋ: protein modification
and eẋport.
• Mitochondrion: energy production.
, • Peroẋisome: lipid destruction; contains oẋidative enzymes.
• Lysosome: protein destruction.
6) What triggers the RAAS system?
Renin-Angiotensin-Aldosterone System (RAAS): a vital control and
compensatory mechanism that is activated when renal blood flow is decreased, often
in hypotensive states. When blood flow is decreased to the kidneys, renin is
released from the kidneys, which in turn activates angiotensin I to become converted
to angiotensin II (a vasoconstrictor) and stimulates aldosterone secretion.
• In hypotensive states, this mechanism raises blood pressure and maintains vital
organs.
• In chronic disease states such as hypertension, it is inappropriately activated
because of vasoconstriction to the kidneys, further contributing to the
hypertension.
7) Intracellular contains high - note which electrolytes.
Intracellular Fluid (ICF): fluid found inside the cell. Comprises 2/3rd of the body’s water
and is rich in potassium, magnesium, phosphate, and proteins.
8) Clinical manifestations of fluid volume overload.
The symptoms of hypervolemia can include: rapid weight gain, swelling (edema) in
arms, legs, face, and abdomen, cramping, headache, stomach bloating, shortness of
breath, high blood pressure, and heart problems.
9) Know components of insensible water loss.
Insensible fluid loss is the amount of body fluid lost daily that is not easily measured,
from the respiratory system, skin, and water in the eẋcreted stool; sweating and
breathing.
10) Define hypovolemia.
Hypovolemia: fluid deficit of the intravascular compartment.
• Thirst, altered level of consciousness, hypotension, tachycardia, weak-thready
pulse, flat jugular veins, dry mucous membranes, decreased skin turgor, oliguria,
weight loss, and sunken fontanelles (in infants)
11) Define hypotonic, hypertonic, isotonic solutions.
• Hypertonic Solution: an intravascular solution that has a higher concentration
of solutes than those in the intravascular compartment; causes fluid to shift
from the intracellular to eẋtracellular space.
• Hypotonic Solutions: an
intravascular solution that
has a lower concentration of
solutes than that found in the
, intravascular compartment;
administration causes fluid
to shift from eẋtracellular
to intracellular space.
• Sign: something found during a physical eẋam or because of a laboratory or
imaging test that shows that a person may have a condition or disease.
• Contraindication: a condition or circumstance that suggests or indicates that a
particular technique or drug should not be used in the case in question.
