Final answer:
The client needs further teaching because they should not resume sexual activity until the UTI is completely cleared.
Step-by-step explanation:
The correct answer is c) I can resume my normal sexual activity without any precautions. This statement indicates a need for further teaching. After being diagnosed with a UTI, it is important for the client to abstain from sexual activity until the infection has completely cleared. Engaging in sexual activity can worsen the infection or introduce new bacteria, prolonging the healing process. The client should be advised to wait until they have finished the full course of antibiotics and have been cleared by their healthcare provider before resuming sexual activity.
