A 45-year-old single mother of three teenaged boys has metastatic breast cancer. Her parents live 750 miles away and have only been able to visit twice since her initial diagnosis 14 months ago.

- A. Denial as a primary coping mechanism.
- B. Support systems and coping strategies.

A client has had multiple sclerosis (MS) for 15 years and has received various drug therapies. What is the primary reason why the nurse has found it difficult to evaluate the effectiveness of the drugs that the client has used?
- A. The client exhibits intolerance to many drugs.
- B. The client experiences spontaneous remissions from time to time.
- C. The client requires multiple drugs simultaneously.
- D. The client endures long periods of exacerbation before the illness responds to a particular drug.
