Answer to Question 1

C
Feedback:
Nicotinic receptors are located in the central nervous system (CNS), the adrenal medulla, the autonomic ganglia, and the neuromuscular junction. Stimulation of nicotinic receptors causes muscle contractions, autonomic responses, and release of norepinephrine from the adrenal medulla. Increased GI motility, decreased heart rate, and pupil constriction are the result of stimulation of the muscarinic receptors.

Answer to Question 2

A
Feedback:
Aminoglycosides are contraindicated in the following conditions: known allergy to any of the aminoglycosides; renal or hepatic disease that could be exacerbated by toxic aminoglycoside effects and that could interfere with drug metabolism and excretion, leading to higher toxicity; preexisting hearing loss, which could be intensified by toxic drug-related adverse effects on the auditory nerve. Ototoxicity should be reported and the drug should be stopped. You would not administer the dose and then call the physician, administer the dose and report information to oncoming nurse, or administer the dose and document the finding in the nurse's notes because each additional dose administered could potentially worsen hearing loss.
