Question Easy: A 45-year-old female presents to her GP with fatigue, weight gain, and cold intolerance. Blood tests reveal low levels of free T4 and elevated TSH. What is the most likely diagnosis? 🩺
A) Hyperthyroidism
B) Hypothyroidism
C) Cushing’s syndrome
D) Addison’s disease
E) Grave’s disease
Explanations & Answers:
Question Easy Answer: B) Hypothyroidism
Question Easy Explanation: The symptoms of fatigue, weight gain, and cold intolerance combined with the lab findings of low free T4 and elevated TSH point towards hypothyroidism. According to NICE guidelines, these findings are classic for an underactive thyroid gland, where the pituitary gland compensates by producing more TSH trying to stimulate thyroid hormone production.
Question Medium: A 60-year-old man is diagnosed with Parkinson’s disease. He is started on a medication that helps to restore dopamine levels in the brain. Which medication is he most likely taking? 💊
A) Rivastigmine
B) Levodopa
C) Carbamazepine
D) Amitriptyline
E) Lamotrigine
Question Medium Answer: B) Levodopa
Question Medium Explanation: Levodopa is the most effective treatment for Parkinson’s disease symptoms as it is a precursor to dopamine. This medication helps to replenish the reduced dopamine levels seen in Parkinson’s disease and is usually combined with carbidopa to prevent peripheral conversion. NICE guidelines recommend levodopa as a first-line treatment for managing motor symptoms in Parkinson’s disease.
Question Hard: A 33-year-old woman presents with sporadic headaches, sweating, and palpitations. Her BP is found to be 165/100 mmHg during an episode. Urinary catecholamines are elevated. What is the most appropriate first-line medication to manage her condition before potential surgical intervention? 🔍
A) Atenolol
B) Labetalol
C) Methyldopa
D) Phenoxybenzamine
E) Doxazosin
Question Hard Answer: E) Doxazosin
Question Hard Explanation: The patient’s symptoms and elevated urinary catecholamines suggest pheochromocytoma. Before surgical resection of the tumour, NICE guidelines recommend starting an alpha-blocker to control hypertension due to catecholamine release. Phenoxybenzamine, a non-selective alpha-blocker, is a traditional choice, but doxazosin, a selective alpha-1 blocker, can also be used. Beta-blockers like atenolol should only be introduced after adequate alpha-blockade to prevent unopposed alpha-adrenergic receptor stimulation.
Medical fact of the day: Did you know that the pituitary gland, often dubbed the “master gland,” weighs less than 1 gram but controls numerous vital hormonal functions in the body, including growth, metabolism, and reproductive health?
