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?
The Correct Answer is ["5"]
To calculate how many milliliters (mL) of metoprolol 1 mg/mL solution should be administered to deliver a 5 mg IV bolus dose, you can use the following formula:
Dose (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case:
Desired dose = 5 mg
Concentration = 1 mg/mL
Dose (mL) = 5 mg / 1 mg/mL = 5 mL
Therefore, the nurse should administer 5 mL of metoprolol 1 mg/mL solution per dose to deliver a 5 mg IV bolus for heart rate control.

Correct Answer is ["B","E"]
Explanation
A. Confirm that the room number matches the medical record.Room numbers should never be used as a sole method to identify a client. Room assignments can change, and relying on them could lead to errors.
B. Compare the client identification number to the blood component tag number.Matching the client identification number to the blood component tag ensures the blood is being administered to the correct client. This is a key step in preventing transfusion errors.
C. Verify the provider's prescription with another RN.While this is an important step in the blood administration process, it is not specifically related to identifying the client.
D. Ask the client to verbalize if the blood type is Rh-negative or positive.Clients may not know their blood type, and relying on their verbal confirmation is unsafe. The blood type must be confirmed through laboratory testing and matched with the blood being administered.
E. Scan the barcode on the client's identification band.Scanning the barcode on the client’s identification band is a reliable and commonly used method for verifying the client’s identity in modern healthcare settings. This ensures that the blood is administered to the correct client.
Correct Answer is ["1"]
Explanation
If the nurse needs to administer vancomycin 500 mg PO daily divided into four equal doses, and the available capsules are vancomycin 125 mg each, the nurse would administer:
500 mg total daily dose ÷ 4 doses = 125 mg per dose
Since each capsule contains 125 mg of vancomycin, the nurse would administer 1 capsule with each dose.
