A nurse is teaching a client who has a new prescription for sertralihe to treat depression. For which of the following findings should the nurse instruct the client to monitor and report immediately as indicating serotonin syndrome?

A. Atropine: Atropine is not used to treat benzodiazepine toxicity. It is primarily indicated for treating bradycardia, organophosphate poisoning, and certain types of poisoning causing excessive muscarinic effects.
B. Flumazenil: Flumazenil is a benzodiazepine receptor antagonist and is used to reverse the sedative effects of benzodiazepine overdose or toxicity. It competitively inhibits the action of benzodiazepines at the receptor site, reversing their effects.
C. Naloxone: Naloxone is a medication used to reverse opioid overdose by competitively binding to opioid receptors and displacing opioid agonists. It is not effective in treating benzodiazepine toxicity.
D. Activated charcoal: Activated charcoal is used to absorb ingested toxins in cases of poisoning. However, it is not effective in treating benzodiazepine toxicity because benzodiazepines are not effectively absorbed by activated charcoal.

A. 4+ deep-tendon reflexes: Deep-tendon reflexes are typically assessed using a scale ranging from 0 to 4+, with 4+ indicating hyperactive reflexes. In a postpartum client, hyperactive deep-tendon reflexes could indicate a potential complication such as preeclampsia or eclampsia, which require immediate medical attention. Therefore, the nurse should report this finding to the provider promptly.
B. Urine output 2,500 mL/day: A urine output of 2,500 mL/day is within the expected range for a postpartum client and does not require immediate intervention. Adequate urine output is important for assessing renal function and hydration status, but this finding does not indicate an urgent concern.
C. Scant lochia rubra with a few small clots: Scant lochia rubra with small clots is a normal finding in the early postpartum period. Lochia typically progresses from rubra (red) to serosa (pink) to alba (white) over time. As long as the lochia is not excessive or accompanied by large clots, this finding is not concerning and does not require immediate reporting to the provider.
D. Bilateral ankle edema: Mild bilateral ankle edema is common in the postpartum period and is often attributed to hormonal changes and shifts in fluid balance. While the nurse should continue to monitor for signs of worsening edema or other symptoms of preeclampsia, mild edema alone is not typically considered a critical finding requiring immediate reporting to the provider.
