A nurse is assisting an older adult client who sometimes loses her balance while walking. Which of the following devices should the nurse use when helping the client ambulate?

A. It reflects a desire to improve physical fitness, which is a common and generally positive goal. However, if this statement were accompanied by an excessive focus on weight loss or extreme measures to achieve fitness, it could indicate a problem, but on its own, this statement is not clearly indicative of cognitive distortion.
B. It reflects "all-or-nothing thinking," a common cognitive distortion in eating disorders. This pattern of thinking involves seeing things in black and white, where a small lapse in diet is perceived as a complete failure, leading to excessive and irrational behavior, such as consuming more than intended.
C. It shows a strong fear of gaining weight, which is typical in anorexia nervosa. However, it is more a sign of extreme concern about body image rather than a specific cognitive distortion pattern. Cognitive distortions often involve faulty logic or irrational beliefs, and this statement is more about an emotional response to weight gain.
D. Cutting food into small pieces can be a behavioral characteristic or ritual for someone with anorexia nervosa, but it does not necessarily reflect a cognitive distortion on its own. It might be a way to control portions or prolong the eating process, but it is not a direct example of distorted thinking.

A. This vitamin is water-soluble, not fat-soluble. It is important for immune function, collagen synthesis, and antioxidant protection. Since it is water-soluble, it does not require fat for absorption and is not typically included in fat-soluble vitamin supplements.
B. This vitamin is fat-soluble, meaning it requires fat for absorption. In conditions like acute pancreatitis, where fat absorption may be impaired, supplementation with vitamin A might be necessary to ensure adequate levels. Vitamin A is crucial for vision, immune function, and skin health.
C. This is a water-soluble vitamin involved in carbohydrate metabolism and nervous system function. It does not require fat for absorption and is not typically supplemented in cases of impaired fat absorption. It is important but not related to the fat-soluble vitamin needs in pancreatitis.
D. This is also a water-soluble vitamin necessary for red blood cell formation and neurological function. Although it can be affected in conditions of poor absorption, it is not a fat-soluble vitamin. It requires intrinsic factor for absorption in the intestines but does not relate to fat-soluble vitamin supplementation.
