Answer to Question 1
B
Edrophonium is an ultra-short-acting cholinesterase inhibitor used to distinguish between a myasthenic crisis and a cholinesterase inhibitor overdose, because weakness or paralysis can occur with both. If the symptoms are intensified and muscle weakness increases, the crisis is cholinergic, meaning that the patient is having toxic effects from the cholinesterase inhibitor and needs atropine as an antidote. Neostigmine would be given if the patient shows improved muscle strength, because that would indicate that the patient's symptoms are the result of a myasthenic crisis. A second dose of edrophonium would only worsen the symptoms. Pralidoxime is used to treat poisoning caused by irreversible cholinesterase inhibitors.
Answer to Question 2
B
Fluoroquinolone antibiotics increase theophylline levels, so the dose of theophylline may need to be reduced to prevent theophylline toxicity. Changing antibiotics, giving the theophylline once daily, and changing to a LABA are not indicated.
