A patient asked the nurse what cardiac glycosides do to improve his condition.
What is the nurse's best response?

Choice A rationale

Acetaminophen is an analgesic and antipyretic but does not have antitussive properties.

Choice B rationale

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that provides analgesic effects but does not have antitussive properties.

Choice C rationale

Aspirin is an analgesic and anti-inflammatory medication but does not have antitussive properties.

Choice D rationale

Codeine is an opioid that provides both analgesic and antitussive effects. It is commonly used to treat mild to moderate pain and to suppress cough.

Choice A rationale

Cholinergic agonists primarily stimulate the parasympathetic nervous system rather than the central nervous system, affecting activities like digestion, salivation, and decreased heart rate.

Choice B rationale

Parasympathetic nervous system is the correct answer. Cholinergic agonists mimic acetylcholine and stimulate parasympathetic responses, promoting rest-and-digest functions such as reducing heart rate and enhancing glandular secretions.

Choice C rationale

The sympathetic nervous system is not stimulated by cholinergic agonists. Instead, this system is activated by adrenergic agonists, which prepare the body for fight-or-flight responses, increasing heart rate and blood pressure.

Choice D rationale

Voluntary nervous system control is not the primary target of cholinergic agonists. This system governs skeletal muscle movement and is influenced by neuromuscular junctions rather than the autonomic responses modulated by cholinergic drugs. .
