The nursing instructor has been teaching about antivirals, actions and effects. The instructor realizes that a student needs further instruction when the student makes which statement?

A. An increased risk for CNS depression is not typically associated with opioid agonist-antagonists; instead, these medications may produce a ceiling effect on sedation compared to full agonists.

B. Respiratory depression is more commonly associated with full opioid agonists rather than agonist-antagonists. Agonist-antagonists can sometimes counteract respiratory depression caused by full agonists.

C. Opioid withdrawal symptoms can occur when a client who is dependent on full agonist opioids is given an agonist-antagonist, as these medications can displace the agonist from receptors, leading to withdrawal.

D. Hypotension is a possible side effect of opioids but is not a specific concern with the use of agonist-antagonists in the context of opioid therapy.

A. While metoclopramide may have some effect on gastric acid secretion, its primary role is not to reduce it.

B. Metoclopramide primarily enhances gastrointestinal motility, which helps to facilitate gastric emptying and is especially useful in treating conditions like gastroparesis.

C. Metoclopramide does not specifically relieve abdominal pain; it focuses more on motility and nausea.

D. Although metoclopramide does have antiemetic properties, it primarily acts as a dopamine receptor antagonist rather than directly inhibiting serotonin.
