A nurse is reinforcing teaching with an older adult client who is on bed rest about foods high in dietary fiber. Which of the following food items should the nurse indicate is the best source of fiber?

A. Protein intake, especially animal protein (such as meat and dairy), can increase the excretion of calcium and other minerals into the urine, potentially leading to the formation of certain types of kidney stones (like calcium stones). Therefore, clients with a history of kidney stones are generally advised to moderate their intake of animal protein.
B. Some types of tea, particularly black tea, contain oxalates, which are substances that can contribute to the formation of calcium oxalate kidney stones in susceptible individuals. Therefore, clients with kidney

stones may be advised to limit their intake of tea, especially if they have a history of calcium oxalate stones.
C. High dietary sodium intake can increase calcium excretion in the urine, which may lead to the formation of calcium-containing kidney stones. Therefore, clients with kidney stones are often advised to reduce their sodium intake to help prevent stone formation.
D. Adequate fluid intake, primarily in the form of water, is crucial for preventing kidney stones. Increased water intake helps dilute urine and reduces the concentration of stone-forming substances, making it less likely for crystals to form and grow into stones. The goal is typically to produce at least 2 to 2.5 liters (about 8 to 10 cups) of urine per day.

A. Excessive pulmonary secretions can be a sign of airway irritation or infection rather than a direct adverse effect of oxygen therapy. It may warrant further assessment and intervention, but it is not typically attributed to oxygen therapy itself.
B. Dryness and cracking of oral mucous membranes can occur as a result of oxygen therapy. Oxygen delivered at higher concentrations or for prolonged periods can dry out mucous membranes, leading to discomfort and potential cracking.
C. Tachycardia (an elevated heart rate) can occur as a compensatory response to hypoxia or increased metabolic demands rather than as a direct adverse effect of oxygen therapy. However, if oxygen therapy leads to an overcorrection of hypoxemia, it could potentially contribute to changes in heart rate.
D. Poor skin turgor is typically a sign of dehydration or fluid imbalance, not directly related to oxygen therapy. It may be important to assess fluid status in clients receiving oxygen therapy, but poor skin turgor itself is not an adverse effect of oxygen administration.
