Stable vital signs mean what?
Vitals signs are remaining the same as base line set
Coffee-ground emesis
Digested blood that is vomited out and is sign of upper GI bleeding
Melena
Dark sticky feces, covered in digested blood. Sign of upper GI bleeding
Hematochezia
stool containing bright red blood ie hemorrhoids
Hematuria
Blood in pee caused by renal injury or illness
Ecchymosis
Purple bluish colouring under the skin, localized blood collection
Hematoma
A localized collection of blood in the soft tissues after injury
Peripheral pulses
Peripheral pulses are the places where you can feel your heartbeat in your body, like your wrist or neck. Heart strength is related to stroke volume and pulse pressure
Pulse pressure
the difference between the systolic and diastolic pressures
What is the first number in BP
Systolic
What is the last number in BP
Diastolic
Stroke volume
the volume of blood pumped forward with each ventricular contraction
Cardiac output
amount of blood pumped by the heart per minute
SVxHR=CO
Golgi complex
synthesis and packaging of various carbohydrates and protein molecules (enzymes)
Lysosomes
contain digestive enzymes
Ribosomes
contain RNA and protein
Peroxisomes
neutralize toxins, such as alcohol. Found in liver
The body relies on what to maintain its delicate acid base balance?
Buffers
One of the main buffers is
Bicarbonate HCO3
H20 combines with CO2 to make
Carbonic acid
In the lungs carbonic acid breaks down into
water and carbon dioxide
In the kidneys the H2CO3 breaks down into
H+ and HCO3
Baroreceptors
respond to changes in blood pressure, located in carotid artery, aorta, and kidneys
A blood pH greater than 7.45 is
Alkalosis
A blood pH less than 7.35 is
acidosis
A patient is breathing at a rate of 6 per minute, shallow and laboured. What type of acid base imbalance would you expect
Respiratory acidosis
A patient who has been experiencing severe diarrhea for several days. What type of acid base imbalance would you expect?
Metabolic acidosis (loss of sodium bicarb)
A patient who has been experiencing severe vomiting for several days. What type of acid base imbalance would you expect?
Metabolic alkalosis ( loss of stomach acids)
A patient who is hyperventilating due to anxiety may experience what type of imbalance?
Respiratory alkalosis(blowing off CO2)
A patient in diabetic ketoacidosis or sepsis may be experiencing this imbalance?
(Metabolic acidosis)
Patients with DKA often experience Kussmaul respirations (deep, rapid, sighing ventilations) in an attempt to blow off the CO2 and decrease acidosis
Explain the process of the breakdown of glucose to ATP
Glucose is broken down into pyruvic acid
Anaerobic Pathway- the absence of oxygen -> lactic Acid. Oxygen can later convert Lactic acid back to Pyruvic acid otherwise it diffuses to the liver and is metabolized Aerobic Pathway with oxygen -> Acytel Coenzyme A -> Citric Acid Cycle (releases CO2, NADH to the ETS)
Kreb’s Cycle -> ATP is the by-product of the breakdown of CoA, NAD, FAD released and combine with energized electrons -> ETS
What is a virus?
Takes over metabolic process of a host cell and uses the host cell to replicate it.
What is apoptosis?
Normal cell death
What are pyrogens?
Released by white blood cells and causes fever to develop
What is bacteria?
Single cell organisms. That when enter the body reproduce rapidly They possess a capsule that protects them from ingestion and destruction
What structures are part of your immune system?
Tonsils
Spleen
Lymphoid tissue
(Thymus gland and bone marrow- T-lymphocytes mature here)
(Lymph nodes)
skin
Stomach acid
cilia
Basophils
Is a white blood cell contain histamine granules released during inflammatory and allergic response.
Eosinophils
Is a white blood cell release substances that damage or kill parasitic invaders
Neutrophils
Is a white blood cell Most abundant white blood cell, protect against infection, destroy and foreign antigens
Monocytes
Is a white blood cell mature in blood where they differentiate into macrophages. (scavengers for the tissues)
Lymphocytes
Is a white blood cell mediate the acquired immune response. 2 types B lymphocytes and T lymphocytes
Mast cells
Is a white blood cell that plays a role in allergic reactions, immunity and wound healing
What is native immunity
natural immunity, non specific cellular and antibody response that operates as the first line of defense against pathogens
Acquired immunity
acquired immunity, arises when the body is exposed to a foreign substance or disease and produces antibodies to that invader (vaccine or getting the disease)
What is Cell-mediated immunity
T-cell lymphocytes recognize antigens and contribute to the immune response by either secreting cytokins or becoming cytotoxic and killing infected cells
What is Humoural immunity
B-cell lymphocytes produce antibodies, react with a certain antigen, have a compliment of 20 proteins circulating untill needed
Define perfusion
Delivery of oxygen and nutrients and removal of wastes for the cells, organs and tissues by circulatory system.
Define hypoperfusion
Occurs when the level of tissue perfusion decreases below normal
Define Shock
Shock is a medical condition characterized by an abnormal state in which the body fails to receive an adequate supply of oxygen and essential nutrients required for proper cellular metabolism. This results in a disturbance of normal cell functioning and can lead to insufficient blood circulation to vital organs.
What are the two types of shock
Central and peripheral
What are the 2 types of central shock
Cardiogenic and obstructive
What are the two types of peripheral shock
Hypovolaemic and distributive
What is cardiogenic shock
When a heart is unable to pump enough, blood for the bodies needs. Poor, cardiac output.
What is Hypovolaemic shock
Depleted, intravascular volume. Hypovolemic shock occurs when there is a significant loss of blood or fluids from the body, leading to a decrease in the volume of blood circulating in the bloodstream.
What is obstructive shock?
Obstructing tissue perfusion. Obstructive shock is a type of shock that occurs when there is an obstruction in the flow of blood through the circulatory system, preventing the heart from effectively pumping blood.
What is distributive shock?
Distributive shock is when vasodilation occurs, blood vessels open up too wide, causing blood to spread out everywhere. The heart and brain do not get enough blood, leading to low BP and tachycardia.
What are the three kinds of distributive shock?
Septic shock, anaphylactic, shock, and neurological shock
What are symptoms of the first phase of shock 
- Compensated shock 2. Agitation, anxiety, and restlessness. 3. Sense of impending doom. 4. Weak and rapid pulse. 5. Cool clammy or pale skin. 6. Shortness of breath. 7. thirst 8. Normal BP
What are the symptoms of the second face of shock?
- decompensated shock 2. Altered LOC
- laboured breathing. 4. Weak or no pulse. 5. ashen skin. 6. hypotension 7. impending cardiac arrest.
What are the symptoms in the last phase of shock?
Irreversible damage or Death
What is hypotension
Low BP
What is hypertension
High BP
