Which of the following responsibilities should a nurse undertake during postmortem care?

Providing emotional support to family members is a crucial responsibility of a nurse during postmortem care. After a patient's death, family members often experience a range of emotions, including grief, shock, and confusion. The nurse's role includes offering compassionate support, allowing family members to express their feelings and providing comfort during a challenging time. This support can help families process their loss and assist in their emotional healing.

While aspects such as initiating organ donation procedures, arranging funeral services, and facilitating cultural and religious rituals are also important in the context of postmortem care, those responsibilities may not fall directly within the nurse's scope of practice or primary duties. Instead, nurses are typically focused on the immediate task of supporting the family members as they navigate their grief, thus making emotional support a paramount aspect of postmortem care.
