Final answer:
The correct answer is 1 hour later.
Step-by-step explanation:
The correct answer is B) 1 hour after.
When taking sodium polystyrene sulfonate, it is recommended to hold other oral medications for 1 hour after taking it. This is because sodium polystyrene sulfonate can interfere with the absorption of other medications, reducing their effectiveness.
For example, if you take a medication at 8 AM, you should wait until 9 AM to take sodium polystyrene sulfonate to ensure optimum absorption of both medications.
