Final answer:
The nurse should advise the patient to gradually increase activities to avoid relapse rather than waiting due to infectiousness, as hepatitis A does not typically result in a chronic state or lengthy period of communicability post-recovery.
Step-by-step explanation:
The proper response to a client recovering from hepatitis A asking about returning to work would be:
C. "Gradually increase your activities because relapses may occur in those who return to full activity too soon."
Hepatitis A is often a short-term infection and does not become chronic. However, post-infection, patients can experience fatigue and should cautiously resume activities to avoid relapse.
Following recovery from hepatitis A, individuals are not infectious and can return to work once they feel able. The concern with returning to work too quickly is primarily due to the potential for relapse and fatigue, rather than the risk of transmitting the virus to others.
