When taking a saturated solution of potassium iodide (SSKI), the nurse should instruct the patient to:

• A. Sip medication through a straw to prevent tooth staining.
• B. Double the dose if a dose is missed.
• C. Expect excessive salivation.
• D. Take before meals.

Answer: (A)

Potassium iodide in a saturated solution can stain tooth enamel if the liquid sits on the teeth. Using a straw helps deliver most of the medication toward the back of the mouth and swallow it quickly, reducing contact with the front teeth. After taking, rinse the mouth or brush to remove any residue and protect the teeth. Doubling the dose if a dose is missed is unsafe and can lead to iodide toxicity. Excessive salivation is not a typical expected effect, and taking before meals is not necessary for preventing staining. The key safety point is to minimize contact with teeth by sipping through a straw and then rinsing.
