A nurse is preparing to administer metoprolol 5 mg IV bolus to a client for heart rate control. Available is metoprolol injection 1 mg/mL. How many mL should the nurse administerperdose?

A. Furosemide 10mg IV bolus every 12 hours:

Furosemide is a loop diuretic commonly used in heart failure management to reduce fluid overload. The prescribed dose of 10 mg IV bolus every 12 hours is within the typical range for furosemide administration in acute heart failure.

B. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain:

Morphine sulfate is often used in the management of acute pain, including pain associated with myocardial infarction. The prescribed dose of 2 mg IV bolus every 2 hours PRN for pain is appropriate and aligns with standard pain management protocols.

C. Laboratory testing of serum potassium upon admission:

It is common practice to perform laboratory testing, including serum potassium levels, upon admission for clients with acute heart failure, especially if they are receiving diuretics or other medications that can affect electrolyte balance. This prescription is appropriate and necessary for monitoring the client's condition.

D. 0.9% normal saline IV at 150 mL/hr continuous:

This prescription raises a concern because administering 0.9% normal saline at a rate of 150 mL/hr continuously may lead to fluid overload in a client with acute heart failure. The rate of IV fluid administration should be carefully assessed based on the client's fluid status, renal function, and hemodynamic parameters to avoid exacerbating heart failure symptoms.

A. Notify the blood bank of the discrepancy:

This choice suggests that there is a discrepancy between the blood type of the unit on hand (type B) and the client's blood type (type AB). However, in reality, there is no discrepancy in this case because individuals with type AB blood are universal recipients and can receive blood from donors of any blood type, including type B. Therefore, there is no need to notify the blood bank of any discrepancy.

B. Administer the blood as ordered:

This choice is the correct action. Type AB individuals are known as universal recipients because they can safely receive blood from donors of any blood type (A, B, AB, or O) without causing a major transfusion reaction. Since the client has type AB blood and the unit of blood on hand is type B, the nurse can administer the blood as ordered without concerns about blood type compatibility.

C. Complete an incident report:

Completing an incident report is typically done when an unexpected event or error occurs during patient care. In this scenario, there is no error or unexpected event related to blood type compatibility, so there is no need to complete an incident report.

D. Contact the provider for further orders:

Contacting the provider for further orders would be necessary if there were a specific reason or concern related to the blood transfusion that requires clarification or additional instructions. However, in this case, there are no issues with blood type compatibility, so contacting the provider is not necessary.
