/in /by

Ms. Blake is an older adult with diabetes and has been too ill to get out of bed for 2 days. She has had a severe cough and has been unable to eat or drink during this time. She has a history of Type I diabetes. On admission her laboratory values show:
Sodium (Na+)
156 mEq/L H
Potassium (K+)
4.0 mEq/L N
Chloride (Cl–)
115 mEq/L H
Arterial blood gases (ABGs)
pH- 7.30; Pco2-40; Po2-70; HCO3-20
METABOLIC ACIDOSIS with respiratory compensation, High anion gap
Normal values
Sodium (Na+)
136-146 mEq/L
Potassium (K+)
3.5-5.1 mEq/L
Chloride (Cl–)
98-106 mEq/L
Arterial blood gases (ABGs)
pH- 7.35-7.45
Pco2- 35-45 mmHg
Po2-80-100 mmHg
HCO3–22-28 mEq/L

Flu? Pneumonia?
Based on these reasons what tests would you order?
Accu check? CXR? Lactic Acid level, serum and urine ketone levels
Describe the molecular mechanism of the development of ketoacidosis. (p. 744) *Pt’s who develop DKA do so bc bicarbonate buffering does not occur, which begins the development of metabolic acidosis
pH 7.30 = acid
CO2 40 = Normal
O2 70 = Low
HCO3 20 = acid
