Question 6# Print Question

With respect to diabetic ketoacidosis (DKA), which ONE of the following statements is TRUE?

A. Kussmaul breathing (deep rapid respiration) is the result of elevated serum osmolality due to hyperglycaemia
B. Standard urine ward tests detect acetoacetate but not beta-hydroxybutyrate
C. The presence of metabolic alkalosis with normal or elevated HCO3 excludes the diagnosis
D. Hyperkalaemia is likely to develop because the acidosis is corrected with treatment


Question 7# Print Question

Regarding the management of DKA, which ONE of the following statements is TRUE?

A. A loading dose of insulin is recommended in both adults and children
B. The water deficit of an average adult is approximately 100 mL/kg or 5–10 L
C. Initial hypokalaemia <3.5 mmol/L indicates less severe disease
D. When venous pH is <7.2, sodium bicarbonate is recommended to correct metabolic acidosis


Question 8# Print Question

Regarding complications that may occur due to treatment of DKA, all of the following are true EXCEPT

A. Severe hypokalaemia may cause cardiac arrest
B. Hyperchloraemic normal anion gap (AG) metabolic acidosis may develop
C. If the neurological state is altered during therapy, intravenous mannitol should be given only when a head CT confirms cerebral oedema
D. Hypo-phosphataemia is a feature


Question 9# Print Question

Regarding hyperglycaemic hyperosmolar state (HHS), which ONE of the following statements is TRUE?

A. HHS is associated with significantly higher mortality than DKA
B. Onset is often rapid following intercurrent illness
C. Blood glucose is generally elevated to the same level as in patients with DKA
D. Serum osmolality remains in the normal range


Question 10# Print Question

In the management of HHS, which ONE of the following statements is TRUE?

A. Since patients have a degree of insulin resistance, initial insulin therapy is indicated at a higher rate than for management of DKA
B. Potassium deficit is lower than in DKA, so replacement therapy is not usually required
C. Initial corrected hyper-natraemia indicates a good prognosis
D. Heparin is indicated preventing thromboembolic events
