Which of the following describes an adverse reaction of Narcan?

Narcan, or naloxone, is an opioid antagonist used to reverse the effects of opioid overdose. When administering Narcan, it is important to be aware of potential adverse reactions that may occur.

Each listed option represents a valid and recognized adverse reaction associated with Narcan. Palpitations can occur as the body responds to the sudden reversal of opioids, particularly in individuals with underlying cardiovascular conditions. Severe hypotension, while not as common, can also occur when opioid sedation is abruptly counteracted, leading to rapid changes in cardiovascular status. Excitement and tremors may arise as the opioid effects are negated, resulting in symptoms of withdrawal in opioid-dependent individuals.

By selecting all of the above as the answer, it encompasses the range of potential adverse reactions that practitioners should monitor for when administrating Narcan. Being aware of these possible side effects is crucial for ensuring patient safety and effectively managing any adverse events that might arise during treatment.
