How to diagnose an acid base disorder?
ABG
Etiology of respiratory acidosis
Depression of respiratory center
Lung disease
S/S of respiratory acidosis
Neuro symptoms
Vasodilation
Patients with respiratory acidosis rely on ___ to maintain oxygen
Hypoxic drive
Etiology of respiratory alkalosis
Increased ventilation
Etiology of metabolic acidosis
Increased ingestion of acids
Inability to renally excrete acid
Excess loss of bicarb
Calculate anion gap
Na - (Cl + HCO3)
Etiology of normal anion gap metabolic acidosis
Loss of bicarb
Etiology of elevated anion gap metabolic acidosis
Ingestion of exogenous acid
Elevation of endogenous acid
Etiology of metabolic alkalosis
Excess bicarb
Excess loss of acid
Volume depletion
How to use ABG for acid-base disorders?
- Look at pH
- Look at CO2
- Look at bicarb
MC risk factors for bladder cancer
Smoking
MC type of bladder cancer
Urothelial cell carcinoma
S/S of bladder cancer
Hematuria
Painless
Diagnosis of bladder cancer
Cystoscopy with biopsy
Stages of bladder cancer
CIS: only in bladder lining
Ta: large but still in bladder lining
T1: into connective tissue layer
T2: into muscle layer
T3: into fat layer
T4: full thickness
Treatment of bladder cancer
Superficial (CIS, Ta, T1): transurethral resection
Invasive (T2+): radical cystectomy with urinary diversion
Preferred method of access for hemodialysis
AV fistula
Etiology of isotonic fluid volume deficit
Decreased fluid intake
Excess fluid loss
Third spacing of fluid
S/S of isotonic fluid volume deficit
Dehydration
Management of isotonic fluid volume deficit
Replace fluids with NS
Etiology of isotonic fluid volume excess
Decreased elimination of fluids (CHF, liver failure)
Increased intake of fluids
S/S of isotonic fluid volume excess
Edema
Increased urine output
Treatment of isotonic fluid volume excess
Correction of underlying cause
Diuretics
Restrict fluid and Na intake
Correction of Na when hyperglycemia is present
Corrected Na = measured Na + (0.2 x glucose - 100)
S/S of hyponatremia
Neuro symptoms
Treatment of hyponatremia
Fluid restriction
Hypertonic saline
Diuresis
S/S of hypernatremia
Neuro symptoms
Treatment of hypernatremia
Fluid replacement
S/S of hypokalemia
Cardiac symptoms
Muscle cramps
Fatigue
GI symptoms
U wave on EKG
