A physician prescribes clomiphene citrate (Clomid, Serophene) for a woman experiencing infertility. She is very concerned about the risk of multiple births. The nurse’s most appropriate response is:

“This is a legitimate concern. Would you like to discuss this further before your treatment begins?”

“No one has ever had more than triplets with Clomid.” “Ovulation will be monitored with ultrasound so this will

not happen.” “Ten percent is a very low risk, so you don’t need to

worry too much.”
