1. Which food provides a 1-ounce serving of grains for a preschool child?

• A. 1 cup of ready-to-eat cereal flakes
• B. 1⁄2 slice of whole wheat bread
• C. 1⁄2 of a 6-inch flour tortilla
• D. 1 cup of cooked rice

Correct answer: A

Rationale: The correct answer is A: 1 cup of ready-to-eat cereal flakes. For a preschool child, 1 cup of ready-to-eat cereal flakes provides a 1-ounce serving of grains, meeting the requirement. Choice B, 1⁄2 slice of whole wheat bread, is not the correct answer as it does not constitute a 1-ounce serving of grains. Similarly, choice C, 1⁄2 of a 6-inch flour tortilla, does not offer a 1-ounce serving of grains. Choice D, 1 cup of cooked rice, also does not provide a 1-ounce serving of grains for a preschool child, making it an incorrect choice.

2. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?

• A. No—absorbed compounds show up in urine, not feces
• B. Yes—absorbed compounds show up in feces, not urine
• C.
• D.

Correct answer: A

Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.

3. The nurse knows that after receiving the blood from the blood bank, it should be administered within:

• A. 1 hour
• B. 2 hours
• C. 4 hours
• D. 6 hours

Correct answer: D

Rationale: Blood transfusions need to be administered promptly after receiving the blood from the blood bank to ensure patient safety and effectiveness. Waiting too long can lead to complications such as bacterial growth in the blood product, which can be harmful when infused. Administering the blood within 6 hours is crucial to prevent such risks. Choices A, B, and C are incorrect because waiting for 1, 2, or 4 hours respectively can increase the likelihood of complications associated with delayed transfusion.

4. Which factor contributes to the development of bone diseases in patients with Chronic Kidney Disease (CKD) due to retention?

• A. Iron
• B. Sodium
• C. Potassium
• D. Phosphorus

Correct answer: D

Rationale: The correct answer is phosphorus. Retention of phosphorus in patients with Chronic Kidney Disease (CKD) contributes to the development of bone disorders, including osteodystrophy, because it disrupts the balance of calcium and phosphorus in the body. This imbalance leads to a variety of bone diseases. The other options - iron, sodium, and potassium - while important in the overall metabolic function, are not directly linked to the development of bone diseases in CKD patients due to retention.

5. Which substance would most likely need to be restricted in patients with heart failure who use diuretics to help reduce fluid retention?

• A. potassium
• B. magnesium
• C. sodium
• D. chloride

Correct answer: C

Rationale: Sodium restriction is crucial in heart failure management to prevent fluid retention, which can worsen symptoms of heart failure.
