A nurse is caring for a client whose current bag of total parenteral nutrition (TPN) has finished infusing, and the next bag is not yet available. Which of the following fluids should the nurse prepare to administer?

A) Hematuria: Hematuria, or blood in the urine, is not typically associated with an allergic reaction to cefaclor. Instead, it may indicate other conditions such as urinary tract infection, kidney stones, or trauma to the urinary tract. While allergic reactions can affect the urinary system, hematuria is not a common manifestation.

B) Pruritus: Pruritus, or itching, is a classic symptom of an allergic reaction to medications, including antibiotics like cefaclor. Itching may occur on the skin or mucous membranes and can range from mild to severe. It is often accompanied by other allergic symptoms such as rash, hives, or swelling. Therefore, the presence of pruritus should alert the nurse to a potential allergic reaction to cefaclor.

C) Slurred speech: Slurred speech is not a typical manifestation of an allergic reaction to cefaclor. It is more commonly associated with neurological conditions, intoxication, stroke, or side effects of certain medications, rather than an allergic response to antibiotics.

D) Tremor: Tremor, or involuntary shaking, is not a characteristic sign of an allergic reaction to cefaclor. Tremors can have various causes, including neurological disorders, medication side effects, or metabolic abnormalities. While tremors can occur in severe allergic reactions (anaphylaxis), they are not among the primary symptoms.

A) Insomnia: While insomnia can be a side effect of some medications, it is not commonly associated with carbamazepine. Therefore, it is not a priority adverse effect for the client to monitor.

B) Blurred vision: This is the correct answer. Blurred vision is a common adverse effect of carbamazepine. It can occur due to the medication's effects on the central nervous system ’nd may indicate the need for dose adjustment or further evaluation by the healthcare provider. Clients should be instructed to report any changes in vision promptly.

C) Tachypnea: Tachypnea, or rapid breathing, is not typically associated with carbamazepine use. While respiratory depression is a concern with some medications, it is not a common adverse effect of carbamazepine.

D) Metallic taste: Metallic taste is a less common adverse effect of carbamazepine. While it may occur, it is not as prevalent or significant as blurred vision, which can impact the client's daily activities and safety.
