Final answer:
Clients involving severe trauma, post-operative care requiring special equipment, unexplained severe symptoms, and serious cardiac conditions must be assigned to an experienced RN.
Step-by-step explanation:
The clients who must be assigned to an experienced RN are those with conditions requiring complex assessment and interventions, as their care necessitates a higher level of expertise and judgement. These include:
- A client who was in an automobile crash and sustained multiple injuries.
- A client who has returned from surgery and has a chest tube in place.
- A client with a severe headache of unknown origin.
- A client with chest pain who has a history of arteriosclerosis.
Clients with chronic back pain related to a workplace injury or with abdominal cramps related to food poisoning may not require an experienced RN unless there are complications or other factors increasing the complexity of their conditions.
