A nurse is assessing an outbreak of mumps among school-age children. Using the epidemiological triangle, the nurse should recognize that which of the following is the host?

. Engage the family in informal conversation. The first step in caring for a client with dementia is to establish a relationship of trust and comfort with the client and their family. Engaging the family in informal conversation can help the nurse gain insight into the family's needs and concerns, as well as provide an opportunity to establish rapport. Encouraging the family to join a support group, providing information about respite care, and educating the family regarding the progression of dementia are important steps in caring for a client with dementia, but they should follow the initial step of engaging the family in informal conversation.

When caring for a client with terminal cancer who expresses a desire to discontinue enteral tube feedings, the nurse's priority is to ensure that the client's wishes are respected and appropriate steps are taken. The most suitable action is:

c) Explain the process for completing a living will.

A living will is a legal document that outlines a person's preferences regarding medical treatment in the event they are unable to communicate their wishes. In this situation, the client can express their desire to forgo enteral tube feedings through a living will, ensuring that their wishes are documented and legally recognized.

The other options may not be as appropriate:

a) Request the facility chaplain to visit the client:While spiritual and emotional support is important, the immediate concern is ensuring the client's autonomy in decision-making regarding medical interventions.

b) Ask the client to sign an informed consent form:Informed consent typically pertains to specific medical procedures, and discontinuing enteral tube feedings is more aligned with the broader context of advance care planning.

d) Complete an against medical advice form:This form is typically used when a patient refuses a recommended treatment against the medical team's advice. However, in this case, the client is expressing their own treatment preferences, and the focus should be on facilitating advance care planning and documentation.
