Diabetic emergencies are acute complications of diabetes that can be life-threatening and require immediate medical attention. The main types include:
Hypoglycemia: Occurs when blood sugar levels drop too low, often due to excessive insulin, skipped meals, or increased physical activity. Symptoms include sweating, shakiness, confusion, rapid heartbeat, and in severe cases, seizures or loss of consciousness. Immediate treatment involves consuming fast-acting carbohydrates like glucose tablets or juice, followed by a longer-acting source like a sandwich.
Hyperglycemia: Involves elevated blood sugar levels, which can lead to diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS). Causes include insufficient insulin, illness, or stress. Symptoms may include frequent urination, excessive thirst, fatigue, blurred vision, and nausea.
Diabetic Ketoacidosis (DKA): A serious condition primarily affecting people with type 1 diabetes, where the body breaks down fat for energy, producing ketones and acids. It is often triggered by infection, missed insulin doses, or other stressors. Symptoms include fruity breath, abdominal pain, vomiting, and rapid breathing. Treatment requires intravenous fluids, insulin, and electrolyte replacement in a hospital.
Hyperosmolar Hyperglycemic State (HHS): More common in type 2 diabetes, this involves extremely high blood sugar levels without significant ketones. It is often linked to dehydration or illness. Symptoms include severe dehydration, confusion, and seizures. Hospital treatment focuses on fluid replacement and insulin therapy.
Prevention involves regular blood sugar monitoring, adhering to medication plans, maintaining a balanced diet, and recognizing early warning signs. Always seek emergency medical help if symptoms worsen.

Question 1:
What is the primary symptom of severe hypoglycemia in a diabetic patient?
A. Excessive thirst
B. Confusion or loss of consciousness
C. Frequent urination
D. Blurred vision
Answer: B
Explanation: Severe hypoglycemia can cause neuroglycopenia, leading to confusion or loss of consciousness due to low blood glucose levels, requiring immediate intervention like glucose administration.
Question 2:
Which blood glucose level is typically considered an emergency for hypoglycemia?
A. Above 200 mg/dL
B. Between 100-140 mg/dL
C. Below 70 mg/dL
D. Between 140-180 mg/dL
Answer: C
Explanation: Blood glucose below 70 mg/dL indicates hypoglycemia, which can progress to severe symptoms if not treated promptly, potentially leading to seizures or coma.
Question 3:
What is the first-line treatment for a conscious patient experiencing hypoglycemia?
A. Administer insulin
B. Give oral glucose or sugary drinks
C. Provide a high-protein meal
D. Inject glucagon
Answer: B
Explanation: For a conscious patient, quickly raising blood glucose with simple carbohydrates like juice or candy is effective, as it addresses the immediate low blood sugar.
Question 4:
In diabetic ketoacidosis (DKA), what is a key laboratory finding?
A. Low blood pH and high ketones
B. Elevated sodium levels
C. Low blood glucose
D. Normal anion gap
Answer: A
Explanation: DKA involves metabolic acidosis from high ketone bodies, resulting in low blood pH and elevated ketones, often due to insulin deficiency in type 1 diabetes.
Question 5:
What symptom might indicate hyperosmolar hyperglycemic state (HHS) in a diabetic emergency?
A. Fruity breath
B. Extreme dehydration and altered mental status
C. Rapid weight gain
D. Hypoglycemia
Answer: B
Explanation: HHS is characterized by severe hyperglycemia and dehydration, leading to altered mental status, commonly in type 2 diabetes patients with insufficient fluid intake.
Question 6:
How should you position a patient with suspected diabetic coma?
A. Sitting upright
B. On their side in the recovery position
C. Standing with support
D. Flat on their back without elevation
Answer: B
Explanation: The recovery position helps maintain an open airway and prevents aspiration in unconscious patients, which is crucial during diabetic emergencies like hypoglycemia or DKA.
Question 7:
What is a common trigger for diabetic ketoacidosis?
A. Overeating
B. Infection or illness
C. Excessive exercise
D. High insulin doses
Answer: B
Explanation: Infections or illnesses increase insulin resistance and stress hormones, leading to DKA by disrupting glucose metabolism and ketone production.
Question 8:
In a hyperglycemic emergency, what electrolyte imbalance is frequently observed?
A. Hyperkalemia
B. Hyponatremia
C. Hypokalemia
D. Hypercalcemia
Answer: C
Explanation: Hyperglycemic states like DKA cause shifts in potassium, often leading to hypokalemia due to insulin therapy and osmotic diuresis, requiring careful monitoring.
Question 9:
What is the immediate action for a diabetic patient with blood glucose over 600 mg/dL?
A. Administer oral medications
B. Seek medical help and hydrate
C. Exercise vigorously
D. Skip the next insulin dose
Answer: B
Explanation: High blood glucose above 600 mg/dL indicates a hyperglycemic emergency, where hydration and professional medical intervention are essential to prevent complications like HHS.
Question 10:
Which medication is commonly used to treat DKA?
A. Oral sulfonylureas
B. Intravenous insulin
C. Beta-blockers
D. Antihistamines
Answer: B
Explanation: Intravenous insulin is administered to rapidly correct hyperglycemia and ketoacidosis in DKA, helping to restore metabolic balance.
Question 11:
What sign might indicate impending diabetic coma from hyperglycemia?
A. Sweating and tremors
B. Deep, rapid breathing (Kussmaul respirations)
C. Bradycardia
D. Hypertension
Answer: B
Explanation: Kussmaul respirations occur as the body attempts to compensate for metabolic acidosis in conditions like DKA, signaling a severe hyperglycemic emergency.
Question 12:
For a patient in hypoglycemic shock, when should glucagon be used?
A. If the patient is conscious and eating
B. If the patient is unconscious and cannot swallow
C. As a preventive measure before meals
D. Only in type 2 diabetes
Answer: B
Explanation: Glucagon is injected when the patient is unconscious, as it raises blood glucose by promoting glycogen breakdown in the liver when oral intake is not possible.
Question 13:
What is a potential complication of untreated hyperglycemia in diabetes?
A. Hypoglycemic episodes
B. Cerebral edema
C. Weight loss benefits
D. Improved vision
Answer: B
Explanation: Rapid correction of hyperglycemia can lead to cerebral edema, a serious complication, especially in children with DKA, due to fluid shifts in the brain.
Question 14:
In diabetic emergencies, what role does blood ketone testing play?
A. It monitors hydration levels
B. It detects ketosis early in DKA
C. It measures insulin levels directly
D. It assesses exercise tolerance
Answer: B
Explanation: Elevated blood ketones indicate developing ketoacidosis, allowing for early intervention to prevent progression to a full emergency.
Question 15:
What is the typical onset time for symptoms in hypoglycemia versus hyperglycemia?
A. Hypoglycemia is slower, hyperglycemia is rapid
B. Both are rapid
C. Hypoglycemia is rapid, hyperglycemia is slower
D. Neither has a typical onset
Answer: C
Explanation: Hypoglycemia symptoms can appear quickly due to low blood sugar affecting the brain, while hyperglycemia develops more gradually over hours or days.
Question 16:
How does alcohol consumption affect diabetic emergencies?
A. It prevents hypoglycemia
B. It can mask hypoglycemia symptoms
C. It always causes hyperglycemia
D. It improves insulin sensitivity
Answer: B
Explanation: Alcohol can inhibit gluconeogenesis and mask symptoms of hypoglycemia, increasing the risk of severe episodes in diabetic patients.
Question 17:
What is a key difference between DKA and HHS?
A. DKA has higher blood glucose
B. HHS has more pronounced acidosis
C. DKA occurs in type 2 diabetes only
D. HHS has extreme hyperglycemia with minimal ketones
Answer: D
Explanation: HHS features very high blood glucose and dehydration with little to no ketones, unlike DKA which involves significant ketosis and acidosis.
Question 18:
In a diabetic patient, what should be monitored closely during treatment of DKA?
A. Blood pressure only
B. Fluid balance and electrolytes
C. Temperature alone
D. Respiratory rate only
Answer: B
Explanation: Monitoring fluid balance and electrolytes is critical in DKA treatment to prevent complications like hypokalemia or fluid overload from intravenous fluids.
Question 19:
What is the recommended follow-up after a hypoglycemic episode?
A. Discontinue insulin entirely
B. Review and adjust diabetes management plan
C. Increase carbohydrate intake permanently
D. Avoid all exercise
Answer: B
