acidotic
If the pH is <7.35, then it is...
alkalotic
If the pH is >7.45, then it is..
If the pH and bicarb both move in the same direction, then it is metabolic, otherwise it is
respiratory.
What is the rule of Bs for determining if the acid/base balance is respiratory or metabolic?
Metabolic acidosis (both go down)
What is this imbalance:
pH: 7.3
HCO3: 20
, Metabolic alkalosis (both go up)
What is this imbalance?
pH: 7.58
HCO3: 32
Respiratory acidosis
What is this imbalance?
pH: 7.22
HCO3: 35
As the pH goes, so goes my patient, except for potassium
What is the potassium rule with acid-base imbalance?
Everything is UP except potassium
(tachycardia, tachypnea, HTN, seizures, irritability, spastic, diarrhea, borborygmi (increase
bowel sounds) hyperreflexia (3+, 4+) and hypokalemia)
If the pH is over 7.45, what are the symptoms?
Suctioning (because of seizures)
What is the main nursing intervention for a patient with a pH of over 7.45?
Everything is DOWN except potassium
(bradycardia, constipation, absent bowel sounds, flaccid, obtunded, lethargy, coma, hyporeflexia
(0,1+) bradypnea, low bp, hyperkalemia)
If the pH is under 7.35 what are the symptoms?
Pt needs to be ventilated with an Ambu bag (respiratory arrest)
What is the main nursing intervention for a patient with a pH below 7.35?
metabolic acidosis (remember mac kussmaul)
This is the only acid-base imbalance to happen from kussmaul respirations?
Is it lung (if yes pick respiratory) then ask if they are over or under ventilating (over= alkalosis,
under= acidosis)
