A nurse is reviewing a prescription for nystatin 200,000 units in a troche PO 4 times per day. How should the nurse interpret this prescription?

Give the client two troches in the morning and two troches in the evening.

Tell the client to keep the troche under the tongue for 5 min before swallowing it.

Instruct the client to swallow the troche with 240 mL (8 oz) water.

Withhold oral intake until the troche dissolves in the client's mouth.
