1. Each statement is true, except one. Which is the exception?

A. Infant formulas should be discontinued at approximately 1 year of age
B. Low-fat milk is not recommended for children younger than 2 years
C. Special toddler formulas are available but are unnecessary
D. Vitamin D-fortified whole milk should not be provided until 2 years

Correct answer: D

Rationale: The correct answer is D. Vitamin D-fortified whole milk should be provided starting at age 1 after discontinuing breast feeding or infant formulas, not at 2 years. Providing whole milk at age 2 is appropriate. Choices A, B, and C are correct statements: infant formulas are typically discontinued around 1 year of age, low-fat milk is not recommended for children under 2 years, and special toddler formulas are unnecessary.

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. Which of the following statements are true about iron?

A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
B. It is one of the most common nutrient deficiencies in the world.
C. Its absorption is increased by Vitamin C and during pregnancy.
D. Its absorption is increased by tannic acid and calcium in milk.

Correct answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.

4. What principle is used when the client with fever loses heat through giving cooling bed bath to lower body temperature?

A. Radiation C. Evaporation
B. Convection D. Conduction
C.
D.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Water loss can occur from each, except one. Which is the exception?

A. Respiratory inflammation
B. Strenuous exercise
C. Diarrhea
D. Perspiration

Correct answer: D

Rationale: The correct answer is D, Perspiration. Water loss can occur through respiration inflammation, strenuous exercise, and diarrhea. Perspiration, also known as sweating, is a mechanism by which the body regulates temperature and eliminates some waste products, but it is not a cause of water loss. The body loses water through sweating, but this loss is mainly for cooling purposes, and it is not a primary mechanism for water loss like respiration, exercise, or diarrhea.
