Multiple-Choice (A–D), For Each Question.
Each Question Includes The Correct Answer
Expert-Verified explanation
,Which medication would the nurse plan on educating the patient about if the nurse
notes from the patient's chart that the primary health care provider is considering
adding a tricyclic antidepressant (TCA) to the patient's treatment regimen?
A. Doxepin
B. Trazodone
C. Amoxapine
D. Maprotiline
Correct Answer: A. Doxepin
Expert Rationale: Doxepin is classified as a tricyclic antidepressant (TCA), which
functions by inhibiting the reuptake of norepinephrine and serotonin in the central
nervous system, thereby enhancing neurotransmitter levels and improving mood.
Trazodone is classified as a serotonin antagonist and reuptake inhibitor (SARI), not a
TCA. Amoxapine and maprotiline, though sometimes categorized with TCAs due to
structural similarities, have atypical profiles and are less commonly used as
prototypical TCAs. Thus, education would primarily focus on doxepin when a TCA is
ordered.

,Which medication does the nurse anticipate administering to a patient with a
suspected overdose of oxazepam?
A. Naloxone
B. Naltrexone
C. Nalmefene
D. Flumazenil
Correct Answer: D. Flumazenil
Expert Rationale: Oxazepam is a benzodiazepine. Flumazenil acts as a specific
benzodiazepine receptor antagonist and is used as an antidote in benzodiazepine
overdose by competitively inhibiting the action of benzodiazepines at GABA receptor
sites. Naloxone, naltrexone, and nalmefene are opioid antagonists and are not
effective for benzodiazepine toxicity.
---
Which system would the nurse assess to determine whether bethanechol has had a
therapeutic effect?
A. Gastric
, B. Urinary
C. Muscular
D. Neurologic
Correct Answer: B. Urinary
Expert Rationale: Bethanechol is a direct-acting cholinergic agonist primarily indicated
for the management of postoperative and postpartum nonobstructive urinary
retention. Assessment of therapeutic effect is based upon improved urinary output
and bladder emptying, reflecting the drug's action on the detrusor muscle of the
bladder.
---
By which age do the processes of gastric emptying and gastrointestinal (GI) motility,
which are unpredictable in neonates and infants, approach those of adults?
A. 6–8 months
B. 9–10 months
C. 11–12 months
D. 13–14 months
