A nurse is assessing a client who has a prescription for cefaclor. Which of the following findings should the nurse recognize as an indication of an allergic reaction?

A) Document the administration of the medication: Documentation of medication administration is an essential step in the medication administration process, ensuring accurate recording of the time, dose, route, and client's response to the medication. However, before administering a controlled substance, the nurse should first identify the client using two identifiers to prevent medication errors.

B) Identify the client using two identifiers: This is the correct initial action. Verifying the client's identity using two identifiers, such as name and date of birth, is a crucial safety measure to ensure that the medication is administered to the correct individual. By confirming the client's identity, the nurse helps prevent medication errors and promotes patient safety.

C) Remove the medication from the medication dispensing cabinet: While obtaining the medication from the medication dispensing cabinet is necessary for administration, it should occur after confirming the client's identity. Identifying the client using two identifiers is the priority to ensure accurate medication administration.

D) Compare the amount of medication available to the inventory record: Verifying the amount of medication available against the inventory record is an important step in medication management to maintain adequate stock levels and prevent medication shortages. However, it is not the first action the nurse should take before administering a controlled substance. Confirming the client's identity is the priority to ensure safe medication administration.

A) Urinary output: Confusion and pitting edema can be signs of fluid overload, a potential complication of TPN administration. Assessing urinary output can help determine if the client is experiencing fluid overload by evaluating the kidneys' ability to excrete excess fluid. Decreased urinary output may indicate renal impairment or inadequate fluid elimination, which can exacerbate fluid overload and contribute to symptoms such as confusion and edema.

B) Blood glucose level: Monitoring blood glucose levels is important in clients receiving TPN, especially if they have diabetes or are at risk of hyperglycemia due to TPN's high glucose content. However, in this scenario, the client's symptoms of confusion and pitting edema suggest a more immediate concern related to fluid status rather than glucose regulation.

C) Weight: Monitoring weight is essential in assessing fluid balance and detecting changes in hydration status. However, assessing weight may not provide immediate information on the client's current fluid overload status. While weight changes over time can indicate fluid retention or loss, assessing urinary output is more direct in evaluating the client's response to slowing the TPN infusion rate.

D) Heart rate: Changes in heart rate can occur in response to fluid volume overload or dehydration. However, assessing heart rate may not provide immediate information on the client's current fluid status. Monitoring heart rate is important in assessing cardiovascular function but may not be the most relevant assessment immediately after slowing the TPN infusion rate in a client with signs of fluid overload
