B. Stop metformin and start glucose insulin potassium infusion (GIK)
C. Stop metformin and start s.c. intermediate insulin twice daily
D. Stop metformin and start insulin infusion

Answer 25

D. Stop metformin and start insulin infusion

Note: to manage inpatient hyperglycemia we use (basal-bolus + sliding scale insulin SSI) strategy. I will summarize this strategy into steps:
1. Calculate total daily dose TDD which is usually 0.5 Unit/Kg except for 3 conditions “if Cr>1.5 / GFR<60 , age >65, BG <10 mmol/l” we use 0.3 units/Kg instead of 0.5
2. Divide TDD into 50% basal (long acting) given at night before sleep and 50% nutritional insulin (rapid acting) before each meal or use mix (intermediate with short acting insulin e.g. Novolin) twice a day “that’s why answer C is wrong”
3. For SSI, take 5% of TDD this is the number of unit you will administer for every 2.2 mmol/l increase in BG e.g. TDD=50, 5% of 50= 2.5 (round the number down to the nearest whole number in this case 2) so you will add 2 units of insulin for every 2.2 increase in BG. If the patient is eating all or most of each meal: Administer as short-acting insulin (or rapid-acting insulin) before each meal and at bedtime. If the patient is not eating (NPO): Administer as short-acting
insulin every 6 hours
4. Adjust as needed (hypoglycemia: reduce 20% of basal insulin and/or 2 unit from
SSI) (persistent BG> 7.8 with no episodes of hypoglycemia: increase Basal by 20% and/or increase SSI by 2 units

Note: Thyroid hormone affects the rate of bone replacement. Too much thyroid
hormone (i.e. thyroxine) in your body speeds the rate at which bone is lost. If this
happens too fast the osteoblasts may not be able to replace the bone loss quickly
enough.

Question 40

30-year-old female, who has a persistent cough of 5-6 months duration. She had no nasal symptoms & no obvious triggers. She does not complain of heart burn. The cough gets worse mainly at night.

Question 41

A 19-year-old male, with persistent sputum that ranges from clear to yellow to sometime green and purulent. He had previous 2 episodes of hemoptysis. He has had multiple chest infections.

a. Cystic lesions with thickening of bronchial walls b. Normal
c. Alveolar infiltrates
d. Obliteration of the left costophrenic angle

Answer 41

a. Cystic lesions with thickening of bronchial walls b

FYI: Rhonchi are sounds are caused by movement of fluid and secretions in larger airways, and are cleared with coughing. This patient has bronchiectasis most probably due to cystic fibrosis (hints: purulent sputum, hemoptysis, and recurrent chest infections. The cardinal finding of later stages of cystic fibrosis is the presence of bronchial wall thickening. These begin as cylindrical and progress through varicoid to cystic forms. However this is found clearly on CT and CXR can usually be normal in a lot of cases. Hopefully in the exam the question would be clearer.

Question 55

A 64-year-old obese male presented with dyspnea, lower limb edema and abdominal distention. He drinks alcohol occasionally. His LFTs were normal. Serum albumin was 37 g/L.

Dyspnea, lower limb edema and abdominal distention are manifestations of heart failure. SAAG = Serum albumin – Ascitic albumin, SAAG in this stem is > 11.1, therefore indicating a transudate cause. Also, ascitic fluid total protein is used to differentiate the causes of ascites if ascitic or serum albumin is not given, ascitic total protein > 25 is indicative of heart failure.

What would you find in such a patient?
A. Low urine sodium
B. Low renin
C. TSH receptor antibodies
D. High DHEA
E. 21-hydroxylase antibodies

Answer 82

E. 21-hydroxylase antibodies

Note:
1) orthostatic hypotension ” Glucocorticoids play an important role in catecholamine-induced vasoconstriction and myocardial contractility.”
2) hyponatremia ”Glucocorticoids inhibit ADH secretion and thereby prevent excessive water retention. With adrenal insufficiency, ADH secretion is disinhibited causing increased reabsorption of free water with subsequent dilution hyponatremia.
3) hypoglycemia “Glucocorticoids inhibit peripheral glucose utilization and increase gluconeogenesis”

These are the symptoms of low cortisol level (hyporcortisolism). 21-hydroxlase is an enzyme that is produced predominantly in the adrenal cortex and involved in
steroidogenesis. Deficiency of this enzyme is the most common cause of congenital
adrenal hyperplasia.

C. Recurrent hypoglycemia is not significant in a patient with coronary artery disease
D. Alcohol accelerates gluconeogenesis causing hypoglycemia unawareness
E. Recurrent asymptomatic hypoglycemia has no effect on higher cognitive
function

Answer 112

B. In diabetes mellitus type 1, glucagon response to hypoglycemia parallels insulin release contributing to hypoglycemic unawareness

Note: Insulin-dependent individuals with diabetes are at risk for a severe hypoglycemic event that may predispose them to several repeat episodes during which the normal counter regulatory mechanisms that protect against hypoglycemia fail to be activated. This state of hypoglycemia unawareness is characterized by a failure of glucagon release, preventing mobilization of endogenous glucose stores from the liver. Hypoglycemia unawareness characterized by the onset of neuroglycopenia before the appearance of autonomic warning symptoms.

Neurogenic/autonomic
Increased sympathetic activity: tremor, pallor, anxiety, tachycardia, sweating, and palpitations
Increased parasympathetic activity: hunger, paresthesias, nausea, and vomiting

Neuroglycopenic
Agitation, confusion, behavioral changes Fatigue
Seizure, focal neurological signs
Somnolence → obtundation → stupor → coma → death

Question 116

A 25-year old female with type 1 diabetes mellitus on insulin and diabetic nephropathy. Her glucose levels are high and uncontrolled despite taking insulin 3 times daily.

A. Increase in the synthesis of insulin by B-cells
B. Worsening of renal function
C. Increased glucose in the urine
D. She is taking steroids
