A student asks the pharmacology instructor to explain the action of anticholinergic agents.
What would be the instructor's best response?
They compete with serotonin for muscarinic acetylcholine receptor sites.
They increase norepinephrine at the neuromuscular junction.
They block nicotinic receptors.
They act to block the effects of the parasympathetic nervous system.
The Correct Answer is D
Choice A rationale
Serotonin does not compete with anticholinergic agents at muscarinic acetylcholine receptor sites; anticholinergics target these receptors to inhibit the parasympathetic nervous system.
Choice B rationale
Anticholinergics do not increase norepinephrine at the neuromuscular junction.
Choice C rationale
Nicotinic receptors are primarily affected by different classes of drugs, such as neuromuscular blockers.
Choice D rationale
Anticholinergics inhibit the actions of the parasympathetic nervous system by blocking muscarinic receptors, reducing bodily functions like saliva production, digestion, and urination.

Correct Answer is D
Explanation
Choice A rationale
Determining the type of pain is secondary to assessing pain severity.
Choice B rationale
Intravenous opioids are strong and should be considered only after evaluating pain severity.
Choice C rationale
Administering acetaminophen without assessing pain severity first is not appropriate.
Choice D rationale
Asking the patient to rate their pain helps gauge severity, guiding further pain management steps.
Correct Answer is A
Explanation
Choice A rationale
Asking the patient what time of day the medication is taken can help identify if taking it at a different time might alleviate sleep disturbances. SSRIs like sertraline can cause insomnia if taken later in the day.
Choice B rationale
Recommending a weekly dosage is inappropriate and could potentially disrupt the therapeutic effect. SSRIs should be taken daily, as prescribed.
Choice C rationale
Counseling the patient to take the medication at bedtime could worsen sleep disturbances, as sertraline may cause insomnia in some individuals. Timing should be adjusted based on patient response.
Choice D rationale
Suggesting a lower dose without consulting the provider may not address the issue effectively and could reduce the efficacy of the medication. Dosage adjustments should be made based on clinical assessment and provider recommendation.
