Question 1

Which is false regarding the treatment of a myxoedema coma?

Accepted Answer

Thyroxine should not be given in full dosage prior to blood results in the treatment of myxoedema coma because of the risk of precipitating adverse effects, especially in the elderly or those with heart disease. Initial treatment should be cautious, and adjustments should be made based on clinical response and laboratory results.

Question 2

Which is not a feature of hypothyroidism?

Accepted Answer

Opthalmopathy, particularly Graves' ophthalmopathy, is more commonly associated with hyperthyroidism, especially Graves' disease, rather than hypothyroidism. The other options listed are typical features of hypothyroidism.

Question 3

Which drug is not a possible precipitant of myxoedema coma?

Accepted Answer

Ranitidine is not associated with precipitating myxedema coma. Myxedema coma is a severe form of hypothyroidism, and drugs like lithium, amiodarone, benzodiazepines, and phenytoin can interfere with thyroid function or exacerbate an existing hypothyroid condition, but ranitidine, a histamine H2 receptor antagonist used to reduce stomach acid, does not have this effect.
