MRCPUK Endocrinology and Diabetes (Specialty Certificate Examination) Sample Questions:

1. A 61-year-old woman was found incidentally to have a raised serum calcium concentration. She was otherwise well. Her father had undergone a neck operation many years previously.
Investigations:
serum corrected calcium2.78 mmol/L (2.20-2.60)
plasma parathyroid hormone10.8 pmol/L (0.9-5.4)
Her general practitioner thought she had primary hyperparathyroidism.
Which further finding is most likely to cast doubt upon this diagnosis?

A) normal serum phosphate concentration
B) low serum magnesium concentration
C) low urinary calcium excretion
D) normal parathyroid radioisotope scan (sestamibi scan)
E) high serum 25-OH-cholecalciferol

2. A 30-year-old man was reviewed in the diabetes clinic. He had type 1 diabetes mellitus of 6 months' duration, treated with subcutaneous insulin in a basal bolus regimen (short-acting insulin three times daily; long-acting insulin once daily).
Investigations:
haemoglobin A1c52 mmol/mol (20-42)
At what arterialised venous blood glucose threshold would a patient typically expect to develop neuroglycopenic symptoms?

A) 3.1-3.4 mmol/L
B) 3.5-3.9 mmol/L
C) <2.3 mmol/L
D) 2.7-3.0 mmol/L
E) 2.3-2.6 mmol/L

3. A 25-year-old woman who was 4 months pregnant presented with weight loss of 3 kg over the previous 4 weeks, associated with intermittent palpitations, tremor and feeling of warmth. She was not taking any medication.
On examination, her pulse was 100 beats per minute and regular, and her blood pressure was 130/60 mmHg. A symmetrical non-tender goitre was palpable, with an audible bruit. There was no exophthalmos.
Investigations:
serum thyroid-stimulating hormone<0.1 mU/L (0.4-5.0)
serum free T445.2 pmol/L (10.0-22.0)
serum free T322.8 pmol/L (3.0-7.0)
anti-thyroid stimulating hormone receptor
antibodies40 U/L (<7)
What is the most appropriate treatment?

A) propylthiouracil
B) subtotal thyroidectomy
C) propranolol
D) radioactive iodine
E) carbimazole

4. A 28-year-old man presented to his optician with a 6-month history of gradually deteriorating vision. He was found to have a visual field defect and was referred urgently to an ophthalmologist who confirmed the finding, and arranged the following investigations.
Investigations (at 09.00 h):
serum cortisol300 nmol/L (200-700) serum testosterone6.5 nmol/L (9.0-35.0) plasma follicle-stimulating hormone1.2 U/L (1.0-7.0) plasma luteinising hormone1.3 U/L (1.0-10.0) serum thyroid-stimulating hormone2.4 mU/L (0.4-5.0) serum free T411.1 pmol/L (10.0-22.0)
What is the most important next investigation?

A) adrenocorticotropic hormone
B) insulin stress test
C) short tetracosactide (Synacthen@) test
D) random growth hormone
E) prolactin

5. A 32-year-old woman presented at 34 weeks of pregnancy, after an episode of vaginal bleeding. Gestational diabetes had been diagnosed at 28 weeks and insulin was started at 29 weeks. Her pre-pregnancy body mass index was 32 kg/m2 (18-25) and there was no family history of diabetes. She was treated with betamethasone 12 mg over 2 days. She was taking 60 units of insulin subcutaneously daily (40 units prandial in three divided doses, and 20 units intermediate-acting insulin), which had been unchanged for 3 weeks.
On examination, she was apyrexial, her pulse was 96 beats per minute and her blood pressure was 124/74 mmHg. Urinalysis showed blood 1+, protein 1+, glucose 2+, ketones 3+.
Investigations:
serum sodium134 mmol/L (137-144)
serum potassium3.8 mmol/L (3.5-4.9)
serum chloride105 mmol/L (95-107) serum urea5.0 mmol/L (2.5-7.0) serum creatinine90 umol/L (60-110) random plasma glucose7.2 mmol/L
What is the most appropriate next step in management?

A) continue to monitor blood glucose in hospital
B) discharge and monitor blood glucose at home
C) start intravenous insulin
D) increase subcutaneous insulin doses by 2-4 units
E) measure venous bicarbonate
