A person with type 1 diabetes has vomiting, abdominal pain, and deep rapid breathing. Glucose is 385 mg/dL, β-hydroxybutyrate is 5.2 mmol/L, pH is 7.18, and bicarbonate is 12 mmol/L. Which interpretation best fits these findings?

  1. A

    DKA, with metabolic acidosis and significant ketonemia

  2. B

    HHS, because glucose is elevated

  3. C

    Uncomplicated hyperglycemia

  4. D

    Hypoglycemia with respiratory compensation

An adult with DKA is dehydrated and has no known heart or kidney failure. Which approach best describes typical early fluid management?

  1. A

    Begin isotonic IV fluid resuscitation, individualize it to the patient, and frequently reassess clinical status and fluid balance.

  2. B

    Restrict fluids because the glucose is elevated.

  3. C

    Give hypotonic fluid rapidly to correct dehydration.

  4. D

    Monitor glucose only; electrolyte checks are unnecessary.

Select all situations that can be associated with DKA despite a glucose level below 200 mg/dL.

  1. A

    Reduced food intake

  2. B

    Pregnancy

  3. C

    SGLT2-inhibitor use

  4. D

An adult with DKA has a potassium concentration of 3.2 mmol/L. What is the safest initial approach to insulin?

  1. A

    Withhold insulin initially and replace potassium according to protocol; start insulin once potassium is above the protocol threshold.

  2. B

    Start IV insulin immediately because insulin will raise the blood potassium concentration.

  3. C

    Give bicarbonate to correct the potassium concentration.

  4. D

    Stop all fluids until the potassium concentration normalizes.

A patient arrives with suspected DKA, dry mucous membranes, tachycardia, and confusion. Select all appropriate elements of the initial approach.

  1. A

    Assess airway, breathing, and circulation.

  2. B

    Check vital signs, mental status, and hydration.

  3. C

    Obtain urgent glucose, electrolyte, ketone, and acid–base studies.

  4. D

    Look for possible triggers such as infection or missed insulin.

  5. E

    Delay assessment until the patient can drink fluids.

During DKA treatment, a patient's glucose falls to 230 mg/dL while ketones and acidosis remain elevated. What is the usual treatment principle?

  1. A

    Stop insulin as soon as glucose falls below 250 mg/dL.

  2. B

    Add dextrose-containing IV fluid as indicated and continue insulin with ongoing monitoring.

  3. C

    Stop all IV fluids.

  4. D

    Give an oral carbohydrate meal and discontinue monitoring.

Which statement about bicarbonate treatment in adult DKA is most accurate?

  1. A

    Give bicarbonate whenever bicarbonate is below 18 mmol/L.

  2. B

    Do not use bicarbonate routinely; clinicians may consider it for severe acidemia, such as pH below 7.0.

  3. C

    Use bicarbonate instead of insulin and fluids.

  4. D

    Give bicarbonate to avoid potassium monitoring.

During DKA treatment, a patient’s glucose falls to 230 mg/dL, but blood ketones and acidosis remain elevated. Which treatment principle is most appropriate?

  1. A

    Stop insulin as soon as glucose falls below 250 mg/dL, even if ketones remain elevated.

  2. B

    Add dextrose-containing IV fluid as indicated and continue insulin to clear ketones, with ongoing monitoring.

  3. C

    Stop IV fluids once glucose falls below 250 mg/dL.

  4. D

    Give an oral carbohydrate meal and discontinue monitoring.

Which findings best support that adult DKA has resolved and that transition from IV insulin can be considered?

  1. A

    Glucose is below 250 mg/dL, regardless of ketone or acid–base results.

  2. B

    β-hydroxybutyrate is below 0.6 mmol/L and acidosis has resolved, with pH at least 7.3 or bicarbonate at least 18 mmol/L; clinical assessment guides transition.

  3. C

    Urine output has increased, regardless of laboratory results.

  4. D

    The patient has received one dose of subcutaneous insulin.

A patient with type 2 diabetes taking an SGLT2 inhibitor presents with nausea and rapid breathing. Glucose is 184 mg/dL, β-hydroxybutyrate is 4.1 mmol/L, and pH is 7.25. Which conclusion is most appropriate?

  1. A

    DKA is ruled out because the glucose is below 200 mg/dL.

  2. B

    Euglycemic DKA is possible and requires urgent evaluation.

  3. C

    This is HHS because ketones are elevated.

  4. D

    The ketone result is irrelevant when glucose is near normal.
