OMSB Endocrine & Diabetes Nursing Practice Questions
Diabetes is one of the most heavily tested topics for Gulf nurses. Expect hypoglycaemia, DKA, insulin safety and thyroid and adrenal emergencies. Below are 5 free sample questions for the OMSB nursing exam, each with the answer and a rationale.
What this topic covers
- Hypoglycaemia recognition and treatment
- DKA vs HHS
- Insulin types, timing and injection technique
- Sick-day rules and Ramadan fasting safety
- Thyroid storm and post-thyroidectomy care
- Adrenal crisis, SIADH and diabetes insipidus
The full bank has 91 endocrine & diabetes nursing questions, part of 1,500 questions across 16 nursing topics.

1. Which group of symptoms is classically associated with hyperglycaemia?
- A. Cold intolerance, weight gain and constipation
- B. Sweating, tremor and palpitations
- C. Polyuria, polydipsia and polyphagia
- D. Bradycardia, hypothermia and lethargy
Show answer and rationale
High blood glucose causes osmotic diuresis (polyuria), leading to thirst (polydipsia), and cellular starvation causes hunger (polyphagia). Sweating, tremor and palpitations are adrenergic signs of hypoglycaemia.

2. A patient asks what the HbA1c test measures. Which explanation is correct?
- A. The amount of insulin the pancreas is producing
- B. Average blood glucose over roughly the previous 2–3 months
- C. Blood glucose at the exact time the sample is taken
- D. Glucose levels over the previous 24 hours only
Show answer and rationale
Glucose binds to haemoglobin over the red cell's lifespan, so HbA1c reflects average glycaemia over about 2–3 months. It does not show daily fluctuations or insulin production.

3. A patient taking insulin plans to start playing football twice a week. Which advice is most appropriate?
- A. Check glucose before exercise and carry fast-acting carbohydrate
- B. Exercise only when blood glucose is below 4.0 mmol/L (72 mg/dL)
- C. Omit all insulin doses on exercise days
- D. Avoid eating anything for 4 hours before exercise
Show answer and rationale
Exercise increases glucose uptake and can cause hypoglycaemia during or hours after activity, so glucose checks and carrying fast-acting carbohydrate are essential. Omitting all insulin risks hyperglycaemia and ketosis, especially in type 1 diabetes.

4. A patient with Addison's disease presents with vomiting, confusion, BP 76/40 mmHg and glucose 3.1 mmol/L (56 mg/dL). Which prescribed treatment is the priority?
- A. Intravenous furosemide to protect the kidneys
- B. Intravenous hydrocortisone with 0.9% sodium chloride and dextrose
- C. Oral fludrocortisone with increased dietary salt
- D. Subcutaneous insulin with potassium replacement
Show answer and rationale
Adrenal crisis is treated urgently with IV hydrocortisone and aggressive IV fluids, with dextrose to correct hypoglycaemia. Oral medicines are unsuitable for a vomiting, shocked patient, and diuretics or insulin would worsen the situation.
Reference: Lewis Medical-Surgical Nursing – adrenal crisis
5. On the first day after transsphenoidal hypophysectomy, a patient's urine output is 400 mL/h for 2 hours with a specific gravity of 1.002. What should the nurse do?
- A. Report the findings promptly as possible diabetes insipidus
- B. Restrict the patient's oral fluid intake
- C. Encourage the patient to cough and deep breathe
- D. Document this as a normal post-operative diuresis
Show answer and rationale
Very high output of dilute urine after pituitary surgery suggests diabetes insipidus, which can rapidly cause dehydration and hypernatraemia and needs prompt treatment. Coughing is avoided after this surgery because it raises intracranial pressure.
Reference: Lewis Medical-Surgical Nursing – pituitary surgery
Study tip
If a diabetic patient is confused or sweaty, check the blood glucose first. Treating hypoglycaemia comes before almost everything else.
