A nurse is preparing to administer a blood component to a client. Which blood component is responsible for promoting clot formation and controlling bleeding?

A) Incorrect: A slight increase in blood pressure is not a significant vital sign alteration that requires immediate reporting before initiating the transfusion. It could be related to various factors, such as anxiety or pain.

B) Incorrect: A respiratory rate of 22 breaths per minute is within the normal range for an adult and does not require immediate reporting before starting the transfusion.

C) Incorrect: A decrease in heart rate from 88 to 72 beats per minute is not a critical vital sign alteration. As long as the heart rate remains within the client's baseline range, it does not need immediate reporting.

D) Correct: An elevated temperature of 38.5°C (101.3°F) may indicate a fever, which could be a sign of an infection or an adverse reaction to the transfusion. The nurse should report this vital sign alteration to the healthcare provider before proceeding with the transfusion to determine the appropriate course of action.

A) Incorrect: Increasing the rate of the blood transfusion is not the appropriate action when the client is experiencing respiratory distress. Rapid transfusion may exacerbate the TRALI and lead to further complications.

B) Correct: Administering oxygen via a nasal cannula or face mask is a priority action for a client experiencing respiratory distress. Providing supplemental oxygen can help improve oxygenation and prevent further complications.

C) Incorrect: Placing the client in a supine position with legs elevated is not the appropriate action for a client with respiratory distress. This position may worsen the client's breathing difficulties.

D) Incorrect: Restarting the transfusion with a different blood product is not indicated in the presence of suspected TRALI. The nurse's priority is to manage the client's respiratory distress and discontinue the transfusion if necessary.
