The practical nurse (PN) reviews instructions for use of polyethylene glycol with a client scheduled for a colonoscopy. Which instruction should the PN include?

Choice A reason: Restlessness, tachycardia, fever, and hypertension suggest serotonin syndrome, a life-threatening paroxetine side effect due to excessive serotonin. Withholding the dose and contacting the provider prevents further serotonin accumulation, allowing urgent assessment and intervention to stabilize the client’s neurological and cardiovascular status.

Choice B reason: A cooling blanket addresses fever but is not the first action for serotonin syndrome. Withholding paroxetine and consulting the provider are critical to stop the syndrome’s progression, as fever is a symptom, not the cause, making this choice secondary to halting the drug.

Choice C reason: Taking the client to a quiet area may reduce stimulation but does not address serotonin syndrome’s physiological cause. Paroxetine’s serotonin excess drives symptoms, requiring drug cessation and medical intervention, not just reassurance, as this condition can rapidly worsen, making this choice inadequate.

Choice D reason: Administering benzodiazepine and acetaminophen is premature without provider guidance, as serotonin syndrome requires specific treatments, like cyproheptadine. Paroxetine must be stopped first, and the provider consulted to confirm diagnosis and manage symptoms, making this choice unsafe and reactive.

Choice A reason: Immune status is critical before administering the influenza vaccine, as immunocompromised individuals may have reduced vaccine efficacy or increased risk of adverse reactions. Conditions like HIV or chemotherapy weaken immune responses, requiring tailored vaccination strategies. Assessing immune status ensures the vaccine is safe and effective, guiding clinical decisions.

Choice B reason: While age influences vaccine type (e.g., high-dose for older adults), it is less critical than immune status for safety. Age is typically already known from records and does not directly affect immediate vaccine administration decisions. This choice is less relevant compared to immune status evaluation.

Choice C reason: Food allergies are generally irrelevant to influenza vaccines, which are not derived from food allergens. However, egg allergies may be considered for certain vaccines due to manufacturing processes, but this is distinct from food allergies broadly. This choice is incorrect as it lacks direct relevance.

Choice D reason: Gender does not impact influenza vaccine administration. Vaccine efficacy and safety are not significantly influenced by gender-specific physiological differences. This choice is incorrect, as it does not provide critical information needed to ensure the vaccine’s safety or effectiveness for the client.
