1. Which item is typically fortified with iodine to address iodine deficiency in the population?

• A. Flour
• B. Salt
• C. Canned vegetables
• D. Drinking water

Correct answer: B

Rationale: Iodized salt is the correct answer. Iodine deficiency can lead to thyroid problems, so iodine is added to salt to ensure an adequate intake of this essential nutrient. Flour is often fortified with other nutrients like folic acid, iron, and niacin, but not iodine. Canned vegetables and drinking water are not typically fortified with iodine to address deficiency in the population.

2. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

3. A nurse is educating the parent of a preschool-age child about nutrition. Which is the best snack choice for the nurse to recommend to the parent?

• A. Fruit snacks
• B. Mini wheat bagel with peanut butter
• C. White toast with jelly
• D. Sports drink

Correct answer: B

Rationale: The best snack choice for a preschool-age child recommended by the nurse would be a mini wheat bagel with peanut butter. This option provides a good balance of carbohydrates, protein, and healthy fats, making it a more nutritious choice compared to the other options. Fruit snacks may contain added sugars and lack essential nutrients. White toast with jelly is high in simple carbohydrates and sugars, providing less sustained energy. Sports drinks are often high in sugar and not necessary for a preschool-age child's snack.

4. Which of the following ethical principles refers to the duty to do good?

• A. Beneficence
• B. Fidelity
• C. Veracity
• D. Nonmaleficence

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. 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.
