(MDC II) Final QUESTIONS AND VERIFIED
ANSWERS WITH RATIONALES JUST
RELEASED.pdf
Uncompensated
pH and one other value is abnormal
Partial compensation
pH, CO2, and HCO3 are all off
Full compensation
pH is normal
Acidosis
reduces the excitability of cardiovascular muscle, neurons, skeletal muscle, and smooth
muscle.
Alkalosis
increases the sensitivity of excitable tissues allowing them to OVERRESPOND without
stimulation
ABG considerations
- Assess cardiovascular w/ acidosis (cardiac arrest from hyperkalemia)
- Assess neuro status
- Fall precautions
Bicarb HC03
kidney compensation (slow and powerful)
, Respiratory PaC02
Respiratory compensation (fast but limited)
Metabolic acidosis causes
DKA, Starvation, diarrhea, kidney failure, dehydration, liver failure, pancreatitis, heavy
exercise, seizure activity, fever, hypoxia, ischemia, ethanol/methanol intoxication
Metabolic acidosis signs and symptoms
bradycardia, hypotension, thready pulse, CNS depression, hyporeflexia, kussmal resp
(with resp compensation), warm, flushed, dry skin.
Metabolic acidosis treatment
hydration and medication to treat underlying problems (DKA - give insulin).
Metabolic alkalosis causes
antacids, blood transfusion, sodium bicarbonate, total parenteral nutrition (TPN),
prolonged vomiting, nasogastric suctioning, hypercortisolism, hyperaldosteronism,
Loop/Thiazide diuretics.
Metabolic Alkalosis s/s
anxiety, irritability, tetany, seizures, POSITIVE CHVOSTEK, POSITIVE TROUSSEAU,
parathesis, hyperreflexia, muscle cramping/twitching, skeletal muscle weakness,
Tachycardia, norm/low BP, increased Digoxin toxicity, decreased respiratory effort
(muscle weakness).
metabolic alkalosis treatment
restore fluid/electrolyte imbalances
Respiratory acidosis cause
