Step-by-step explanation:
The nurse should include instruction A) Engage in safe sex practices using barrier methods in the teaching for the client newly diagnosed with hepatitis C.
Hepatitis C is primarily transmitted through exposure to infected blood. While sexual transmission is less common, it is still possible. Therefore, engaging in safe sex practices using barrier methods, such as condoms, can help prevent the spread of the virus to sexual partners.
Additionally, the nurse should also emphasize the importance of getting tested and treated for hepatitis C and avoiding behaviors that increase the risk of further liver damage, such as excessive alcohol consumption.
