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 D
Explanation
Choice A reason:
Monitor your child’s temperature daily: Monitoring temperature is important for children with sickle cell anemia as they are prone to infections. A fever can be an early sign of infection, which can be serious for these children. Normal body temperature for children ranges from 36.5°C to 38°C. However, while monitoring temperature is important, it is not the most critical daily advice compared to ensuring adequate hydration.
Choice B Reason:
Restrict outdoor play to 1 hour per day: Limiting outdoor play is not typically necessary unless the child is experiencing extreme fatigue or pain. Physical activity is generally encouraged to maintain overall health, but it should be balanced with rest and hydration. Therefore, this advice is not as crucial as ensuring the child stays hydrated.
Choice C Reason:
Apply cold compresses when your child expresses pain: Cold compresses are not recommended for managing pain in sickle cell anemia. Instead, warm compresses or heating pads are often suggested to help relieve pain by improving blood flow. Cold can cause vasoconstriction, which may worsen pain and complications.
Choice D Reason:
Offer your child fluids frequently to meet their daily fluid goals: Staying well-hydrated is essential for children with sickle cell anemia. Adequate hydration helps prevent sickle cell crises by reducing blood viscosity and promoting better blood flow. This is the most appropriate and critical advice for daily care.
Correct Answer is D
Explanation
Choice A reason:
Releasing traction every hour to perform skin care: Releasing traction every hour is not recommended as it can disrupt the alignment and healing process of the fractured femur. Skin care is important, but it should be performed without compromising the traction setup.
Choice B Reason:
Releasing traction once every 8 hours to check circulation: While checking circulation is crucial, releasing traction every 8 hours is not necessary and can interfere with the therapeutic benefits of traction. Circulation can be monitored without releasing the traction.
Choice C Reason:
Maintaining continuous traction until 1 hour before the scheduled surgery: Continuous traction is essential to maintain the alignment of the fractured femur. However, there is no need to release traction 1 hour before surgery unless specifically instructed by the surgical team.
Choice D Reason:
Maintaining continuous traction and checking the position of traction: This is the most appropriate action. Continuous traction ensures proper alignment and healing of the fractured femur. Regularly checking the position of traction helps prevent complications and ensures the effectiveness of the treatment.
