Q

Osmosis

A

the movement of a solvent (water) from an area of lower solute concentration to an area of higher solute concentration.

  • in the picture, water can move in and out but the molecules cannot. so because more molecules are outside the cell the water will leave the cell and make it shrink in sizing.

It is when organs are without oxygen for a certain amount of time they die and there is extremely small way to reverse MODS

36
Q

Carpopedal spasm

A

Contorted position in which the fingers or toes flex in a clawlike manner.
May result from hyperventilation, hypocalcemia, resp. alkalosis

37
Q

Hyponatremia

A

Low sodium level
Swelling of cells
S&S muscle weakness, cramps, coma, convulsions

38
Q

Hypermagnesemia

A

Occurs as a result of kidney insufficiency. The body is unable to remove the magnesium taken in from food or drugs.
Lethargic, bit of shortness of breath, very little reflexes

and pancreatic polypeptide.

40
Q

Hypothalamus

A

An area of the diencephalon (middle part of the brain) that is the primary link between the endocrine system and the nervous system; responsible for control of many body functions, including heart rate, digestion, sexual development, temperature
regulation, emotion, hunger, thirst, and regulation of the sleep cycle

41
Q

Thyroid

A

Produces hormones that regulate the body’s metabolic rate-controlling heart, muscle and digestive function, brain development and bone maintenance, temp

42
Q

Acid / Base measurement.
Normal is 7.35 - 7.45

46
Q

Edema

A

Occurs when there is an increase pressure of the venous vessels to where the arterial side cannot move fluid. This causes fluid to leak out of the vessels into the interstitial space

47
Q

A

Total amount of pressure that causes fluid to go through a filter. Filter can be capillary beds, alveoli, ect.

48
Q

Aka anaphylaxis
Widespread dilation of vessels. Blood pools since the container got bigger than the amount of fluid
Wheezing, urticaria, swelling
Treatment: Epinephrine

51
Q

Septic shock

A

Aka sepsis
Fluid leaks out of the vascular system and causes low fluid in the container, bad infection in the blood
Warm hot skin, elevated core temp, hypotension, difficulty breathing, rapid weak pulse, shallow rapid respirations
Treatment: complex hospital management, including antibiotics, ventilators support

52
Q

Neurogenic shock

A

Spinal cord injury of cervical or thoracic spine
Loss of sympathetic nervous system and vasodilation occur
Bradycardia, low BP, signs of neck/spine injury
Treatment: IV fluids, vasopressors, steroids

53
Q

Hypovolemic shock

A

Aka burn shock, blood or fluid loss
The circulating blood is insufficient in adequate oxygen and nutrients to the body. Exogenous Hypovolemic shock - open wound blood loss or plasma loss from diarrhea or vomiting
Endogenous hypovolemic shock - blood/fluid loss contained in the body
Bleeding, burns, fast HR, low BP
Treatment: ABCs. Control the bleeding, keep airway open, keep pt warm, fluids, surgery

54
Q

Cardiogenic shock

A

Heart can out circulate enough blood to the body
Caused by a loss of 40% or more of the heart muscle due to shock, surgery, cardiac arrest, ventricular wall rupture, ventricular aneurysm
Chest pain, irregular pulse, weak pulse, low BP, cyanosis, cool, clammy, mottled or flushed skin, anxiety, Arles, pulmonary edema
Treatment: if lungs are clear can give fluids, CPAP/BPAP

55
Q

Obstructive shock

A

Occurs when the blood flow becomes blocked in the heart or great vessels
Pulmonary embolism, tension pneumothorax, pericardial tamponade

56
Q

Distributive shock

A

Occurs when widespread dilation of the resistant vessels

Anaphylactic shock, septic shock, neurogenic shock

57
Q

Compensated shock

A

Body is able to compensate for blood loss (15% - 30% blood loss)
BP is above 90 SBP - remains normal or a bit elevated narrowing pulse pressure
RR increase and depth
Positive orthodontic tilt test

58
Q

Decompensated shock

A

Aka uncompensated, progressive, hypotensive shock
BP falling - Less than 90 SBP - can be late sign especially in children and infants
Blood volume drops more than 30%
Compensatory mechs begin to fail

59
Q

Irreversible shock

A

Impending death
BP very low 40% + blood volume loss
Blood gets shunted away from liver, kidney and lungs to preserve the heart and the brain

Aggressive treatment may not work since there could be vital organ damage even if the cause of shock is treated and reversed

60
Q

RAAS

A

Renin-Angiotensin-Aldosterone System

Controls long term BP. Slower acting.

61
Q

Sodium potassium pump

A

3 sodium leave the cell and 2 potassium enter the cell. Uses 1 ATP to activate.
