A nurse is applying cold therapy to a client's face following oral surgery. The nurse should identify that which of the following is a therapeutic effect of cold therapy?

A. Measure the intake and output of a client who has received furosemide: Measuring intake and output is within the scope of practice for assistive personnel. The nurse remains responsible for interpreting the data and notifying the provider of any concerns.

B. Check a client's peripheral IV site for redness or swelling: Assessment of IV sites for complications such as infiltration, phlebitis, or infection requires clinical judgment and should be performed by licensed nursing personnel.

C. Assess the pain level of a client who has received acetaminophen: Pain assessment requires clinical judgment, interpretation of client responses, and knowledge of pain scales. Only licensed nurses should perform pain assessments and determine the effectiveness of interventions.

D. Reinforce teaching with a client about crutch-gait walking: Reinforcing teaching involves understanding and communicating clinical concepts accurately. Even though it may seem routine, instructing or clarifying a gait technique requires nursing knowledge to ensure client safety and proper technique.

A. Headache: Headache can occur during a transfusion reaction but is usually a less urgent symptom. It should be monitored but is not the highest priority.

B. Urticaria: Urticaria (hives) often indicates a mild allergic reaction to the transfusion. It requires intervention but is generally not immediately life-threatening.

C. Dyspnea: Dyspnea signals possible respiratory distress, which may indicate a severe transfusion reaction such as anaphylaxis or transfusion-related acute lung injury (TRALI). This requires immediate attention and reporting to prevent respiratory failure.

D. Hyperthermia: A fever during transfusion suggests a febrile non-hemolytic reaction or infection risk, which is important but typically not as urgent as respiratory distress.
