A nurse is caring for a client who follows a vegan diet. The nurse should identify that the client is at risk for which of the following deficiencies?

A. While it is possible for individuals following a vegan diet to be deficient in magnesium if they do not consume enough plant-based sources, deficiencies in vitamin D are more common due to limited dietary sources and reduced exposure to sunlight.
B. Vitamin C deficiency is rare in individuals following a vegan diet, as many fruits and vegetables are good sources of this nutrient.
C. Vitamin D deficiency is common in individuals following a vegan diet, as the primary dietary sources of vitamin D are animal products such as fatty fish, eggs, and fortified dairy products. Vegans may need to rely on fortified foods or supplements to meet their vitamin D needs.
D. Folic acid deficiency is not typically associated specifically with a vegan diet. However, individuals following any type of restrictive diet should ensure they are consuming adequate amounts of folate-rich foods or consider supplementation if necessary.

Choice A: The recommended daily fiber intake for adults is generally higher than 12 grams. For a balanced diet, women should consume between 22 and 28 grams of fiber per day, and men should consume between 28 and 34 grams per day, depending on their age.

Choice B: Adding 500 calories per day to the diet is typically advised for weight gain, not weight loss. For weight loss, a caloric deficit is usually required, which can be achieved by consuming fewer calories or increasing physical activity.

Choice C: Continuing the current daily caloric intake would not be beneficial if the client's goal is to change their body mass index, especially if their current intake is maintaining a BMI of 28, which is classified as overweight.

Choice D: Referring the client to a weight-loss support group can provide them with emotional support, motivation, and accountability, which are important factors for long-term weight loss success. Support groups can also offer practical advice and a sense of community, which can enhance the weight loss journey.
