A nurse is preparing to administer amoxicillin 100 mg PO every 8 hr to a toddler who weighs 20 kg. The recommended dosage range is 20 to 25 mg/kg/day. Which of the following actions by the nurse is appropriate?

A. While administering 0.9% sodium chloride is an important step to maintain venous access and to help dilute any blood that might still be in the tubing, it is not the first action to take if a transfusion reaction is suspected. This step should occur after the transfusion is stopped and the patient’s safety is ensured.
B. The immediate priority when a transfusion reaction is suspected is to stop the transfusion immediately. This action helps to prevent further exposure to the potentially harmful blood product and mitigates the risk of worsening the reaction. Stopping the transfusion also allows for prompt medical assessment and intervention.
C. Returning the unit of blood to the blood bank is important for investigation and to determine the cause of the reaction, but it should be done after stopping the transfusion and ensuring the client’s safety. The blood bank may require the returned unit to confirm any issues with the blood product.

D. Obtaining a blood sample from the client is crucial for diagnostic purposes and to identify the cause of the reaction, but this should be done after the transfusion has been stopped. The sample may help in diagnosing the type of reaction or in managing it, but it does not address the immediate safety concerns.

A. Abdominal pain is not a direct manifestation of respiratory acidosis. However, it may be associated with other conditions or complications but is not a primary indicator of respiratory acidosis.
B. Lethargy or drowsiness is a common symptom of respiratory acidosis. The increased CO₂ levels lead to an acidic environment that can affect brain function, resulting in decreased alertness, confusion, or drowsiness.
C. Numbness or tingling of the fingers is more commonly associated with respiratory alkalosis, which is characterized by a decreased level of CO₂ and increased blood pH. This condition can cause peripheral numbness and tingling due to altered blood pH affecting nerve function.
D. Dry skin is not a direct manifestation of respiratory acidosis. While it might be a sign of dehydration or other systemic issues, it is not specifically linked to respiratory acidosis.
