The nurse is caring for a client admitted with severe exacerbation of posttraumatic stress disorder that is experiencing flashbacks and hypervigilance. Which is the priority for the nurse to address when caring for this client?

Choice A reason: Offering dessert to stop yelling uses bargaining, not distraction, and may reinforce agitation in Alzheimer’s, where cortical and amygdala damage impairs emotional regulation. This approach risks escalating distress by focusing on the behavior, which the client cannot control due to neurocognitive deficits, making it ineffective.

Choice B reason: Asking if the client wants to finish the meal focuses on the agitation’s context, potentially worsening distress in Alzheimer’s due to impaired reasoning from cortical degeneration. This confrontational approach does not redirect attention, failing to leverage preserved procedural memory, which distraction techniques use to calm neurobiological agitation.

Choice C reason: Suggesting to watch television is a distraction technique, redirecting attention from agitation triggers in Alzheimer’s. By engaging preserved sensory and procedural memory, it reduces amygdala-driven emotional distress without confronting cognitive deficits, aligning with neurobiological strategies to manage agitation and promote calm in dementia care.

Choice D reason: Stating misunderstanding focuses on the client’s communication deficits, likely increasing frustration in Alzheimer’s due to hippocampal and cortical damage. This does not distract from agitation triggers and may exacerbate distress, as the client cannot process or correct their behavior, making it an ineffective response compared to redirection.

Choice A reason: Tylenol with Codeine (acetaminophen and codeine) in tablet form (1T) typically refers to a standard dose, but in liquid form, the concentration varies. Assuming a common elixir (120 mg acetaminophen/12 mg codeine per 5 mL), 15 mL delivers the standard dose. 15.5 mL slightly exceeds this, risking overdose and potential hepatotoxicity from acetaminophen, making it incorrect.

Choice B reason: Tylenol with Codeine elixir is commonly 120 mg acetaminophen and 12 mg codeine per 5 mL. One tablet equivalent (1T) typically corresponds to 15 mL, delivering 360 mg acetaminophen and 36 mg codeine, aligning with standard dosing for pain relief. This volume ensures therapeutic efficacy without exceeding safe limits, matching pharmacological guidelines.

Choice C reason: A 40 mL dose of Tylenol with Codeine elixir (120 mg acetaminophen/12 mg codeine per 5 mL) would deliver 960 mg acetaminophen and 96 mg codeine, far exceeding safe single-dose limits. This risks acetaminophen-induced liver toxicity and opioid-related respiratory depression, as it disrupts the therapeutic window, making this choice scientifically inappropriate.

Choice D reason: A 30 mL dose of Tylenol with Codeine elixir (120 mg acetaminophen/12 mg codeine per 5 mL) provides 720 mg acetaminophen and 72 mg codeine, doubling a typical single dose. This excessive amount increases the risk of hepatotoxicity and opioid side effects like sedation or respiratory depression, rendering it unsuitable for standard administration.
