A nurse is preparing to administer a hazardous IV medication to a client. Which of the following actions should the nurse take?

A) Instruct the ’lient that their central line dressing must be changed every 24 hr: While it's essential to maintain proper hygiene a’d care for a central line to prevent infection, changing the dressing every 24 hours may not be necessary. The frequency of dressing changes depends on institutional policies and the client's condition. Providing accurate informat’on about dressing changes based on specific guidelines is important for the client's safety and the prevention of central l’ne-related infections.

B) Instruct the client to weigh themselves daily and record their weight: This is the correct instruction. Monitoring daily weight allows for the assessment of fluid status and the effectiveness of TPN therapy. Weight gain or loss can indicate fluid retention or depletion, respectively, which may necessitate adjustments to the TPN prescription. Recording daily weights provides valuable data for healthcare providers to evaluate the client's response to TPN and make appropriate m’difications to the treatment plan.

C) Instruct the client that one container of TPN may infuse for up to 72 hr: The duration of TPN administration varies depending on factors such as the client's nutritional needs, medical condition, ’nd the stability of the TPN solution. While some TPN solutions may be stable for up to 24-48 hours, infusing for 72 hours could increase the risk of contamination and compromise the integrity of the solution, leading to adverse effects. Providing accurate information about the duration of TPN infusion based on the specific prescription ensures the client's safety and the efficacy of therapy.

D’ Instruct the client to speed up the rate of their TPN infusion if it falls behind schedule: Altering the rate of TPN infusion without healthcare provider guidance can lead to complications such as hyperglycemia, electrolyte imbalances, or fluid overload. TPN infusion rates are carefully prescribed based on the client's nutritional needs and metabolic status’ If the infusion falls behind schedule, it's essential for the client to contact th’ir healthcare provider for guidance on adjusting the infusion rate or managing any potential issues.

A) Give diphenhydramine IM: Diphenhydramine is an antihistamine that can help alleviate allergic symptoms such as itching, hives, and mild allergic reactions. However, in the case of an anaphylactic reaction, which is a severe and potentially life-threatening allergic reaction, diphenhydramine alone may not be sufficient. While it can be administered as an adjunctive therapy, it is not the primary intervention for anaphylaxis. Therefore, giving diphenhydramine IM should not be the next action after stopping the medication infusion.

B) Elevate the client's legs and feet: Elevating the client's legs and feet is a supportive measure that can help improve venous return to the heart and mitigate symptoms of hypotension. However, in the context of an anaphylactic reaction, the priority is to address airway compromise and cardiovascular collapse, as these are life-threatening complications. Elevating the legs and feet may be considered after administering epinephrine and ensuring stabilization of the client's airway, breathing, and circulation.

C) Replace the infusion with 0.9% sodium chloride: While stopping the infusion of the offending medication is essential in managing an anaphylactic reaction, replacing it with 0.9% sodium chloride solution alone does not address the systemic effects of anaphylaxis. The priority is to administer medications such as epinephrine to reverse the allergic response and stabilize the client's condition. Therefore, replacing the infusion with 0.9% sodium chloride should not be the next action after stopping the medication infusion.

D) Administer epinephrine IM: Epinephrine is the first-line treatment for anaphylaxis due to its rapid onset of action and ability to reverse bronchoconstriction, vasodilation, and increased vascular permeability associated with the allergic reaction. Administering epinephrine IM helps counteract the severe manifestations of anaphylaxis, including respiratory distress and hypotension. Therefore, it is the most appropriate next action after stopping the medication infusion and assessing the client's respiratory status.
