Septic shock treatment is aimed at:

A. In diabetic ketoacidosis (DKA), serum bicarbonate is typically decreased, not increased. The decrease is due to metabolic acidosis resulting from the accumulation of ketones.

B. Serum potassium is often elevated in DKA initially due to the shift of potassium from inside the cells to the bloodstream as a result of acidosis. However, potassium levels may drop with treatment, especially with insulin administration, which drives potassium back into cells.

C. Urine pH in DKA is often acidic due to the presence of ketones, which are acidic byproducts of fat metabolism. A urine pH of 4.0 indicates aciduria, which is consistent with ketoacidosis.

D. Serum pH in DKA is typically low (below 7.35), indicating acidosis. A serum pH of 7.5 would suggest alkalosis, which is not typical of DKA.

A. Dyspnea is the medical term for shortness of breath or difficulty breathing. It is a subjective sensation of uncomfortable breathing and is the most appropriate term for this client's description.

B. Aspiration refers to the inhalation of food, liquid, or other foreign substances into the airways, which can lead to choking or pneumonia. This does not describe the sensation of shortness of breath.

C. Hemoptysis refers to coughing up blood, which is unrelated to the sensation of shortness of breath described in the question.

D. Orthopnea is shortness of breath that occurs when lying flat, often associated with heart failure. The description in the question does not specifically mention difficulty breathing while lying down.
