A confused but physically healthy older patient eats a diet very high in cereals and breads, with fruit only once per week and little protein. How does the patient's diet impact her current condition?
A) A lack of vitamin A can affect her night vision.
B) A high-calcium diet can lead to problems with kidney stones.
C) The lack of fruit in her diet can contribute to complaints of constipation.
D) A high-carbohydrate diet can stimulate abnormally high release of insulin, which can add to her confusion.
D
Feedback:
An abnormally high release of insulin can cause hypoglycemia, which first presents in the elderly as a confused state. The patient's high-carbohydrate diet could increase her confusion. There is not enough information to support that the patient is experiencing problems with night vision because of a lack of vitamin A. There is also not enough information to support that the patient is experiencing constipation or has a high intake of calcium.
