MDC2 Exam 2
Acidosis
The acid base balance of the blood and other ECF is upset by an excess of hydrogen. Arterial blood pH
below 7.35



Causes of metabolic
•Diabetic Ketoacidosis
•Renal failure
•Starvation
•Diarrhea
•Ileostomy
•Hyperthyroidism
•Pancreatitis
•Liver failure
•Dehydration
•Seizure activity
•Ethanol intoxication
•Aspirin toxicity



metabolic acidosis
too much acid



Hydrogen irons of metabolic acidosis are?
Over Produced
Under eliminated



Bicarbonate irons of metabolic acidosis are?
Under producted
Over eliminated



S/S of Metabolic Acidosis
•Kussmaul's breathing •20bpm
•weak
•Confused
•Hypotension
•Cardiac changes (due to Hyperkalemia)
•Nausea
•Vomiting



Interventions for Metabolic Acidosis
•Hydration
•Antidiarrheal medications
•Monitor Electrolytes (potassium)
•Renal Failure

, •Neuro status
•DKA
•Bicarbonate
•Watch for Respiratory distress



Lab assessment for metabolic acidosis
SERUM POTASSIUM HIGH



Respiratory Acidosis
Respiratory function is impaired, causing problems with O2 and CO2 too much Co2 retained



Respiratory Acidosis causes
•COPD
•SEVERE ASTHMA



Acidosis Interprofessional collaborative care: •CNS changes
Lethargy, confusion, stupor,coma



Acidosis Interprofessional collaborative care: Neuromuscular changes
↓ Muscle tone, deep tendon reflexes, facial paralysis, skeletal muscle weakness



Acidosis Interprofessional collaborative care: Respiratory changes
Kussmaul's breathing



Acidosis Interprofessional collaborative care: Skin changes
Warm, dry, and pink (vasodilation)



Acidosis Interprofessional collaborative care: Cardiovascular changes
•Early: ↑ Heart rate, cardiac output changes
Worsening: •Hyperkalemia; ↓ heart rate; T wave peaked and QRS widened; weak peripheral pulses;
hypotension



Priority problem for patient with respiratory acidosis
Reduce GAS EXCHANGE resulting from underlying pulmonary disease.



Interventions for Respiratory Acidosis
•Focus on improving gas exchange
