A school nurse is concerned about the almost skeletal appearance of one of the high school students. Although all of the following nutritional problems can occur in adolescents, which one is most often associated with a negative self-concept?

A. Has both older and younger siblings: This does not specifically relate to the "sandwich generation" concept.

B. Cares for children and aging parents at the same time: The term "sandwich generation" refers to individuals who are simultaneously caring for their own children and their aging parents.

C. There is a role reversal between parents and self: While this may occur in caregiving situations, it doesn't define the "sandwich generation."

D. Assists own parents and spouse's parents: This is similar to option B but specifically refers to assisting one's own parents and the spouse's parents, not necessarily at the same time.

A. "I will make exercise a part of my daily activities." This is a positive and correct statement. Regular exercise is an important component of a healthy lifestyle and should be encouraged.

B. "I should eat a diet high in fats but low in fiber." This statement is incorrect and indicates a misunderstanding of healthy dietary guidelines. A diet high in fats and low in fiber is not recommended for maintaining health and can lead to various health issues like obesity, heart disease, and digestive problems.

C. "I only have one glass of wine a day with dinner." This statement aligns with moderate alcohol consumption guidelines, which suggest that up to one glass of wine per day for women and two for men can be part of a healthy lifestyle.

D. "I will begin a smoking cessation program this week." This statement reflects a positive health choice. Quitting smoking is one of the most beneficial actions a person can take for their health, reducing risks for many diseases.
