Final answer:
The nurse should administer half a tablet of the 100mg metoprolol tartrate tablet per dose to equal the prescribed 50mg BID.
Step-by-step explanation:
The student is asking how many tablets of metoprolol tartrate should be administered per dose when the order is for 50mg twice daily (BID), but the available tablets are 100mg. To determine the number of tablets per dose, a simple calculation is needed:
- Divide the ordered dose (50mg) by the strength of the tablet available (100mg).
- This calculation yields 0.5, which means half of the 100mg tablet is required for the ordered dose.
So the nurse should administer half a tablet per dose to provide the ordered 50mg of metoprolol tartrate.
