WGU D236 Patho - Megan/Shay’s Study Guides |
Flashcards made from Megan's study guide for
D236 Pathophysiology at WGU.
What is the primary determinant of oncotic pressure? **** Albumin
Form of osmotic pressure exerted by proteins **** Oncotic Pressure
What is the difference between adult and child immunity? **** Naive T Cells
Fluid and electrolyte levels are regulated by _________________, which regulates
actions such as thirst, ADH, the kidneys, and RAAS. **** Osmoreceptors
What are the causes of dehydration? **** #Excessive loss
#Inadequate intake
#Both
What s/sx are associated with dehydration? **** #Dry mucous membranes
#Decreased skin turgor
#Decreased urine output
#Low blood pressure
#Tachycardia
#Weak heart rate
#Confusion
A patient with a viral illness and severe vomiting has an elevated CO2 level and pH of
7.53. She is breathing slowly. What condition does she have? **** Metabolic alkalosis
The patient's pH and CO2 levels are both elevated (moving in the same direction). This
indicates metabolic alkalosis. The CO2 level is high because her respiratory system is
attempting to compensate for the high pH by exhaling less and retaining more CO2.
Normal CO2 level **** 35-45
Normal pH level **** 7.35-7.45
Normal HCO3 level **** 22-26
Michael's pulmonary edema leads to respiratory acidosis. How does pH impact
Michael's basal metabolic panel? Choose 3 answers.
His CO2 level is increased because his lungs have difficulty removing it from the
bloodstream.
,His calcium level is reduced because the elevated concentration of H+ makes it easier
for Ca+ to bind to albumin.
His CO2 level is decreased because his lungs have difficulty adding it into the
bloodstream.
His sodium level is decreased due to hypervolemia.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the
bloodstream, K+ moves from cells into the bloodstream. **** His CO2 level is increased
because his lungs have difficulty removing it from the bloodstream.
His sodium level is decreased due to hypervolemia.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the
bloodstream, K+ moves from cells into the bloodstream.
A hormone panel was done on a patient with congestive heart failure and fluid volume
overload. Which elevated hormone on the patient's chart is indicative of the body's
attempt to reduce the fluid overload?
Antidiuretic hormone (ADH)
Brain natriuretic peptide (BNP)
Aldosterone
Renin **** BNP
BNP is released when fluid volume excess is present.
Normal sodium level **** 135-145
Hyponatremia is indicated by what lab result? S/Sx? **** Na < 135
Loss of energy or fatigue
Nausea and vomiting
Headache
Confusion
Muscle spasms
Low blood pressure
Dark scanty urine
Irritability, disorientation and neurological manifestations
Seizures
,Hypernatremia is indicated by what lab result? S/Sx **** Na > 145
Hypocalcemia is indicated by what lab result? S/Sx? **** Calcium < 8.5
Overexcitability of the muscles
Muscle twitching
Paresthesia (numbness/tingling)
Chvostek and Trousseau sign (twitching on the cheek when touched)
Cardiac dysrhythmias
Hypercalcemia is indicated by what lab result? S/Sx? **** Calcium > 10.5
Muscle weakness
Loss of muscle tone
Spontaneous fractures
Kidney stones
Cardiac dysrhythmias
Normal magnesium level **** 1.6-2.6
Hypomagnesemia is indicated by what lab result? S/Sx? **** Magnesium level < 1.6
Tay-Sachs Disease **** An autosomal recessive inherited genetic disorder caused by a
recessive allele (chromosome 15) that leads to the accumulation of certain lipids in the
brain. Seizures, blindness, and degeneration of motor and mental performance usually
become manifest a few months after birth, followed by death within a few years.
Marfan Syndrome **** Inherited autosomal dominant trait (only one abnormal copy of
the Marfan gene inherited from one parent) FBN1 gene. Genetic connective tissue
disorder that can affect aorta and heart valve structures.
**If one parent has Marfan syndrome, each child has a 50% chance of inheriting the
abnormal gene and developing the condition. If both parents have the condition, the risk
of their child inheriting the abnormal gene and developing Marfan syndrome increases
to 75%.
Turner Syndrome **** A chromosomal disorder in females in which either an X
chromosome is missing, making the person XO instead of XX, or part of one X
chromosome is deleted.
Underdeveloped ovaries (sterile)
Short stature (under 4' 7")
Amenorrhea
Webbing of the neck
Edema
Underdeveloped breasts/wide nipples
Respiratory rate increases during exercise. How does this increased respiratory rate
allow the body to maintain a homeostatic pH level? **** The increased exhalation of
CO2 helps to increase pH.
