Correct Answer: D

Rationale: The correct answer is "I should choose white rice as a side dish." In a low-fiber diet, foods that are low in fiber are recommended to reduce gastrointestinal irritation. White rice is a low-fiber option suitable for this diet. Choices A, B, and C are high-fiber options and not suitable for a low-fiber diet. A fresh pear, refried beans, and bran cereal are all high in fiber, which should be avoided in a low-fiber diet.

Correct Answer: C

Rationale: The correct recommendation for a client with type 1 diabetes mellitus looking for a sweetener is a nonnutritive sugar substitute. Nonnutritive sugar substitutes do not significantly affect blood glucose levels, making them a suitable option for individuals with diabetes. Corn syrup and natural honey are high in sugar and can lead to spikes in blood glucose levels, which is not ideal for someone with diabetes. Guava nectar, while natural, is also high in sugar content and not recommended for individuals with diabetes.

Correct Answer: D

Rationale: Patients with pancreatitis should avoid high-fat foods like cheddar cheese as they can exacerbate symptoms due to the organ's role in fat digestion. Noodles, vegetable soup, and baked fish are generally considered to be lower in fat content and are thus safer choices for individuals with pancreatitis.

Correct Answer: C

Rationale: Vitamin C aids in the absorption of iron by enhancing the body's ability to absorb non-heme iron, which is found in plant-based foods. This vitamin helps convert iron into a form that is more easily absorbed in the intestines. Choices A, B, and D are incorrect because fiber, Vitamin A, and oxalates can actually inhibit the absorption of iron. Fiber can bind to iron and reduce its absorption, Vitamin A does not directly enhance iron absorption, and oxalates found in some foods like spinach and rhubarb can also hinder iron absorption.

Correct Answer: B

Rationale: The correct answer is 0.9% sodium chloride. When a client receiving TPN is awaiting the next container, infusing 0.9% sodium chloride is the appropriate choice to maintain fluid and electrolyte balance. Dextrose solutions are not recommended as they do not provide sufficient nutrition. Lactated Ringer's solution contains electrolytes but lacks essential nutrients found in TPN, making it an inadequate choice during the delay in TPN delivery.
