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) Obtaining a primary and secondary tubing set:
The primary tubing is used for the intravenous access, and the secondary tubing is attached for administering the blood product. This ensures that the blood transfusion will be delivered effectively, and it is a standard practice to use proper IV tubing for blood products to avoid contamination or complications.

B) Ensuring another licensed personnel is available:
. While it is required that two licensed healthcare professionals verify the blood product before starting the transfusion, this action itself is not contraindicated, it is required. Both individuals should independently check the patient's identification, blood type, and the matching of the blood product before administration. Therefore, the answer to the question should not be about ensuring availability of licensed personnel as this is actually a required safety measure, not contraindicated. The actual contraindications involve actions like using inappropriate fluids for transfusion or mismatching blood.

C) Obtaining 0.9% normal saline solution:
This is appropriate and necessary when preparing for a blood transfusion. Normal saline (0.9%) is the only compatible solution that should be used to flush the IV line before and after the transfusion or to prime the blood tubing. Other solutions, such as lactated Ringer's, can cause clotting when mixed with blood, making saline the only appropriate choice.

D) Checking ABO and Rh status of the donor and recipient:
This is essential and mandatory before administering a blood transfusion. It is critical to ensure that the ABO blood group and Rh factor of the donor and recipient are compatible to prevent hemolytic reactions. This compatibility check must be done every time before administering a transfusion, and it is an integral part of ensuring patient safety.

A. Glucagon IM:
Glucagon is used to treat hypoglycemia (low blood sugar), not hyperglycemia. It is typically administered intramuscularly in cases of severe hypoglycemia to rapidly raise blood glucose levels. In acute hyperglycemia, the blood glucose is already elevated, so glucagon is not appropriate. The correct treatment for hyperglycemia includes insulin administration, fluid replacement, and monitoring of electrolytes.

B. Regular insulin IV infusion:
In acute hyperglycemia, particularly in cases of diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS), regular insulin is commonly administered intravenously to reduce blood glucose levels. It acts rapidly to lower blood glucose, and the dose can be adjusted based on the client's response. Therefore, this is an expected intervention in the management of acute hyperglycemia.

C. Potassium laboratory monitoring:
In acute hyperglycemia, particularly during insulin administration, potassium levels should be closely monitored. Insulin can drive potassium into cells, potentially leading to hypokalemia (low potassium levels). Since hyperglycemia treatment can alter electrolyte balance, potassium levels need to be frequently checked to avoid complications like arrhythmias or muscle weakness. This is an important intervention in managing hyperglycemia.

D. IV fluid replacement:
IV fluid replacement is a crucial part of managing acute hyperglycemia, particularly in conditions like DKA and HHS. These conditions cause dehydration due to osmotic diuresis, and fluid replacement helps to restore normal hydration status and support renal function. The nurse would expect IV fluid administration to correct electrolyte imbalances and improve circulatory volume.
