A nurse is preparing a client for an electroencephalogram (EEG). When the client asks what the purpose of the procedure is, what is the nurse's best response?

A) Check the identifying information on the unit of blood against the patient’s ID bracelet:
This is the highest priority to ensure patient safety before beginning a transfusion. The risk of transfusion reactions, including hemolytic reactions due to mismatched blood, makes verifying patient identification critical. The nurse must match the blood product with the patient’s information and confirm that the blood product is correct for the patient. This verification is typically done with a second nurse to ensure safety. If the blood is mismatched, it can lead to severe, potentially life-threatening consequences.

B) Stay with the patient for 60 minutes after starting the transfusion:
While it is important to stay with the patient during the transfusion and monitor for adverse reactions, the highest priority before starting the transfusion is verifying patient and blood product compatibility. After starting the transfusion, staying with the patient for the first 15 minutes is critical for monitoring for early signs of a transfusion reaction, but this action occurs after the blood has been correctly matched and started.

C) Add the blood transfusion as a secondary line to the existing IV:
Ensuring proper identification and blood product matching is more critical than deciding whether to use a secondary IV line. The nurse should verify patient and blood compatibility first and then proceed with setting up the IV line for transfusion.

D) Prime new primary IV tubing with lactated Ringer's solution to use for the transfusion:
Priming IV tubing with lactated Ringer’s solution is incorrect for a blood transfusion. Blood should only be administered with normal saline, as other fluids, including lactated Ringer's solution, can cause clotting or hemolysis when mixed with blood products. This action would not be a safe or appropriate step in preparing for a blood transfusion. The correct solution to prime tubing for blood transfusions is normal saline, and this is secondary to ensuring proper patient identification and blood compatibility.

A) Strains are associated with fractured bone that are tearing blood vessels:
Strains refer to injuries of muscles or tendons due to overuse, overstretching, or tearing. A strain does not typically involve fractured bones or tearing blood vessels. Sprains, on the other hand, involve ligaments, not muscles or tendons, and may or may not involve fractures or tearing of blood vessels.

B) "A strain should be treated with heat in the first 24 hours then ice after:
. The general recommendation for the initial treatment of a strain (and sprain) is rest, ice, compression, and elevation (R.I.C.E.) within the first 24-48 hours. Ice should be applied during this period to reduce swelling and inflammation, not heat. Heat may be used after the first 48 hours to promote healing and reduce muscle stiffness, but it should not be used during the acute phase of the injury.

C) A sprain involves stretching or tearing or tearing of ligaments at a joint:
This is the correct statement. A sprain is an injury to a ligament, which is the tissue connecting bones to other bones. It is typically caused by stretching, overextension, or tearing of the ligament, often resulting from a sudden or awkward movement at a joint. Sprains commonly occur at areas such as the ankle, knee, and wrist.

D) A sprain involves tearing of a muscle body or tendon:
. A sprain involves damage to a ligament, not a muscle or tendon. Damage to muscles or tendons is classified as a strain, not a sprain. Strains refer to overuse or tearing of muscle fibers or tendons, not ligaments.
