A client with chronic kidney disease is receiving IV therapy with a potassium-containing solution. The nurse should carefully monitor the client for which complication?

A) This choice is incorrect because administering IV medications rapidly may increase the risk of an allergic reaction, especially in a client with a history of multiple drug allergies.

B) This choice is incorrect because switching to oral medications may not be appropriate or feasible for all IV medications. The nurse should consider alternative medications only after performing a thorough allergy assessment and consulting with the healthcare provider.

C) This choice is incorrect because the choice of IV catheter gauge is not directly related to preventing allergic reactions. It should be based on the medication's compatibility and viscosity.

D) This choice is correct. A thorough allergy assessment is essential in a client with a history of multiple drug allergies to identify potential allergens and prevent exposure to allergenic medications. The nurse should communicate allergies to the healthcare team and document them in the client's medical record, using allergy alerts or wristbands, to ensure safe medication administration.

A) This choice is correct. The client's sudden onset of hives, facial swelling, and difficulty breathing suggests a Type I (Immediate) hypersensitivity reaction, also known as anaphylaxis. Type I hypersensitivity reactions occur within minutes to hours after exposure to an allergen, leading to the release of histamine and other inflammatory mediators.

B) This choice is incorrect because Type II (Cytotoxic) hypersensitivity reactions involve antibodies attacking specific cells or tissues, leading to cell destruction. They are not associated with the symptoms described by the client.

C) This choice is incorrect because Type III (Immune Complex-Mediated) hypersensitivity reactions involve the formation of immune complexes that deposit in tissues and trigger inflammation, but they do not typically present with generalized hives and facial swelling.

D) This choice is incorrect because Type IV (Delayed) hypersensitivity reactions occur 24 to 72 hours after exposure to an allergen and are mediated by T cells, leading to localized skin reactions like contact dermatitis. They are not associated with the rapid onset of symptoms described by the client.
