Answer to Question 1

B
Feedback:
Adverse effects include photosensitivity, headache, dizziness, nausea, vomiting, dry mouth, and fever. Generally, adverse effects of norfloxacin do not include liver toxicity, bone marrow depression, or congestive heart failure.

Answer to Question 2

A
Feedback:
Maintain a cholinergic blocking drug on standby, such as atropine, to use as an antidote for excessive doses of cholinergic drugs to reverse overdose or counteract severe reactions arising from use of cholinergic agonists. Atropine will block cholinergic effects that are causing this patient's heart rate to decline. Bethanechol will slow the heart rate further whereas propranolol and pseudoephedrine will not reverse the cholinergic stimulation.
