A nurse is teaching an older adult client about vitamin D deficiency. The nurse should encourage the client to consume an adequate amount of vitamin D to prevent which of the following complications?
Dry eyes
Fractures
Infection
Swelling
The Correct Answer is B
Choice A reason: Dry eyes are not caused by vitamin D deficiency, but by other factors such as aging, medication, environmental conditions, or eye diseases. Vitamin D does not have a direct role in eye health or function.
Choice B reason: Fractures are caused by vitamin D deficiency, as vitamin D helps the body absorb calcium, which is essential for bone health and strength. Vitamin D deficiency can lead to osteoporosis, a condition in which the bones become brittle and prone to breaking.
Choice C reason: Infection is not caused by vitamin D deficiency, but by other factors such as exposure to pathogens, weakened immune system, or poor hygiene. Vitamin D may have some role in modulating immune responses, but it is not a primary factor in preventing infection.
Choice D reason: Swelling is not caused by vitamin D deficiency, but by other factors such as injury, inflammation, fluid retention, or allergic reaction. Vitamin D does not have a direct role in regulating fluid balance or reducing inflammation.

Correct Answer is B
Explanation
Choice A reason: Consuming ten percent of total calories from saturated fat is not a part of the DASH diet because it is too high for most adults. The DASH diet recommends consuming less than seven percent of total calories from saturated fat, which translates to about 16 g of saturated fat per day for an average adult who consumes 2,000 calories per day.
Choice B reason: Consuming foods that are high in calcium is a part of the DASH diet because it can help lower blood pressure by relaxing the blood vessels and reducing the force of contraction of the heart. The DASH diet recommends consuming 1,000 to 1,200 mg of calcium per day, which can be obtained from dairy products, leafy greens, beans, nuts, and fortified foods.
Choice C reason: Increasing intake of refined carbohydrates is not a part of the DASH diet because it can raise blood sugar and insulin levels, which can increase blood pressure and damage the blood vessels. The DASH diet recommends consuming 45 to 55 percent of total calories from carbohydrates, but mostly from whole grains, fruits, and vegetables, which are rich in fiber and antioxidants.
Choice D reason: Limiting sodium intake to 3,200 milligrams per day is not a part of the DASH diet because it is too high for most adults. The DASH diet recommends limiting sodium intake to 2,300 milligrams per day or less, which can help lower blood pressure by reducing fluid retention and vascular resistance.
Correct Answer is D
Explanation

Choice C reason: Almonds are incomplete proteins, but they can be combined with other foods to form complete proteins.
