Which of the following food choices contains the least amount of phenylalanine for children with PKU?
Walnuts
Cow’s milk
Bananas
Diet soda with aspartame
The Correct Answer is C
Choice A reason:
Walnuts are a source of protein and contain phenylalanine, an amino acid that individuals with phenylketonuria (PKU) must limit in their diet. While nuts can be a healthy snack for most people, they are not suitable for those with PKU due to their high phenylalanine content. Therefore, walnuts are not the best choice for children with PKU.
Choice B reason:
Cow’s milk is another source of protein and contains significant amounts of phenylalanine. Dairy products, including milk, cheese, and yogurt, are generally high in protein and should be avoided by individuals with PKU. Consuming cow’s milk can lead to elevated levels of phenylalanine in the blood, which can be harmful to children with PKU.
Choice C reason:
Bananas are a fruit that contains very low levels of phenylalanine. Fruits and vegetables are generally safe for individuals with PKU as they are low in protein and phenylalanine. Bananas, in particular, are a good option for children with PKU as they provide essential nutrients without contributing to high phenylalanine levels.
Choice D reason:
Diet soda with aspartame should be avoided by individuals with PKU because aspartame is an artificial sweetener that contains phenylalanine. Consuming products with aspartame can lead to an increase in phenylalanine levels in the blood, which can be harmful to those with PKU. Therefore, diet soda with aspartame is not a suitable choice for children with PKU.

Correct Answer is ["A","B","C"]
Explanation
The correct answers are a) Use a straw to administer the medication, b) Give the medication with vitamin C, and c) It is best to give the medication with food.
Choice A reason:
Using a straw to administer ferrous sulfate is recommended to prevent staining of the teeth. Ferrous sulfate, especially in liquid form, can cause discoloration of the teeth if it comes into direct contact with them. By using a straw, the medication bypasses the teeth, reducing the risk of staining.
Choice B reason:
Giving ferrous sulfate with vitamin C is beneficial because vitamin C enhances the absorption of iron. Vitamin C (ascorbic acid) helps convert iron into a form that is more easily absorbed by the body. Therefore, administering ferrous sulfate with a source of vitamin C, such as orange juice, can improve its effectiveness.
Choice C reason:
It is best to give ferrous sulfate with food to reduce gastrointestinal side effects. While iron is best absorbed on an empty stomach, it can cause stomach upset, nausea, and constipation. Taking the medication with food can help mitigate these side effects, making it more tolerable for the child.
Choice D reason:
Giving ferrous sulfate with milk is not recommended. Dairy products, including milk, can interfere with the absorption of iron. Calcium in milk binds with iron, reducing its bioavailability and effectiveness. Therefore, it is best to avoid giving ferrous sulfate with milk or other dairy products.
Correct Answer is C
Explanation
Choice A reason:
Extracellular hyperglycemia refers to high blood sugar levels outside the cells. While hyperglycemia is a common feature of diabetic ketoacidosis (DKA), it is not the direct cause of the condition. DKA occurs when the body cannot use glucose for energy due to a lack of insulin, leading to the breakdown of fat and protein for energy, which produces ketones and causes acidosis.
Choice B Reason:
Hypoglycemia, or low blood sugar, is not associated with diabetic ketoacidosis. In fact, DKA is characterized by high blood sugar levels. Hypoglycemia is a separate condition that can occur in individuals with diabetes, particularly if they take too much insulin or skip meals.
Choice C Reason:
The use of fat and protein as an energy source is the primary mechanism behind diabetic ketoacidosis. When insulin is deficient, the body cannot utilize glucose for energy. As a result, it breaks down fat and protein to produce energy. This process generates ketones, which are acidic and lead to the development of ketoacidosis.
Choice D Reason:
Increased cellular metabolism of glucose is not related to diabetic ketoacidosis. In DKA, the problem is that cells cannot use glucose effectively due to a lack of insulin. Instead, the body resorts to breaking down fat and protein for energy, leading to the production of ketones and acidosis.
