Final answer:
The nurse should educate the client about why it's important to inform sexual contacts so they can receive treatment to prevent the spread of chlamydia.
Step-by-step explanation:
The nurse should educate the client about why it's important to inform sexual contacts so they can receive treatment. Although chlamydia may not cause immediate harm like some other sexually transmitted infections (STIs), it still has the potential to cause complications if left untreated. Chlamydia can lead to pelvic inflammatory disease (PID), which can result in infertility or ectopic pregnancy in females. By informing sexual contacts, the client can help prevent the spread of the infection and protect the health of others.
