A patient diagnosed with a somatic symptom disorder has the nursing diagnosis: Interrupted family processes, related to patient's disabling symptoms as evidenced by the spouse and children assuming roles and tasks that previously belonged to patient. An appropriate outcome is that the patient will:
- A. assume roles and functions of the other family members.
- B. demonstrate a resumption of former roles and tasks.
- C. focus energy on problems occurring in the family.
- D. rely on family members to meet his or her personal needs.
Correct Answer: B
Rationale: The correct answer is B: demonstrate a resumption of former roles and tasks. This outcome implies that the patient will regain the ability to fulfill their own roles and tasks within the family, indicating improvement in the interrupted family processes. This aligns with the goal of promoting the patient's independence and reducing the burden on other family members.
Choice A is incorrect because having the patient assume roles and functions of other family members does not address the underlying issue of the patient's somatic symptom disorder and may lead to further dysfunction within the family.
Choice C is incorrect as it suggests the patient should focus on problems in the family, which may not directly address the interrupted family processes related to the patient's symptoms.
Choice D is incorrect as it promotes dependency on family members to meet the patient's personal needs, which does not encourage the patient to regain their former roles and tasks within the family.
