What would be the best source of drug information for a nurse?

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. .

Choice A rationale

The rebound effect is typically associated with decongestants rather than topical nasal steroids. It occurs when nasal congestion worsens after stopping decongestant use.

Choice B rationale

Local ulceration is a potential adverse reaction to topical nasal steroids due to the localized irritation and thinning of the nasal mucosa with prolonged use.

Choice C rationale

Increased nasal drainage is not a common adverse reaction to topical nasal steroids. These medications typically reduce inflammation and decrease nasal drainage.

Choice D rationale

Suppression of healing is not an adverse reaction associated with topical nasal steroids. These drugs are more likely to reduce inflammation and promote healing of the nasal mucosa.
