A nurse is planning care for a toddler who has epiglottitis. Which of the following interventions should the nurse include?

A. Incorrect. Encouraging clients to establish a timeline for grieving might not be appropriate or helpful, as grief processes are individual and non-linear.
B. Correct. Coping with changes in family dynamics is a relevant topic for a support group of this nature, as suicide often brings significant family changes.
C. Incorrect. Focusing on preventing suicide is not the primary goal of this support group; coping and healing are more appropriate.
D. Incorrect. Allowing clients to share negative aspects of their relationship can promote emotional healing and understanding, which is essential in this context.

Based on the information provided, the following findings require immediate follow-up:

A. Witnessing their family's death: The client witnessing their family's death during the tornado is a traumatic event that may have significant psychological implications. This finding requires immediate attention and further assessment to address the client's emotional well-being.

B. Caregiver reporting client acting differently than usual: The caregiver's concern about the client "not being themselves lately" is important and may indicate changes in the client's behavior or mental state. This requires immediate follow-up to explore the reasons behind the change in behavior.

D. Startles easily during thunderstorm: The client's heightened startle response during thunderstorms may be indicative of increased anxiety or trauma-related symptoms. This finding requires further evaluation and intervention.

G. Smoking marijuana to clear their mind: The client's use of marijuana to cope with their emotions and thoughts indicates maladaptive coping mechanisms. This finding requires immediate follow-up to address substance use and provide appropriate support.

H. Client experiences nightmares: The client's nightmares are likely related to the traumatic event they witnessed, and they may be experiencing symptoms of post-traumatic stress disorder (PTSD). This finding requires immediate attention and assessment to provide appropriate mental health support.

The other findings mentioned (C, E, F) are not concerning based on the information provided and do not require immediate follow-up. However, they may still be relevant for the client's overall assessment and care plan. The nurse should prioritize addressing the immediate mental health and emotional needs of the client, given the recent traumatic experience they went through.
