1. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?

A. Both statements are true
B. Both statements are false
C. The first statement is true; the second is false
D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are indeed true. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.

2. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

A. reducing cholesterol synthesis
B. suppressing inflammation
C. reducing blood clotting
D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

3. A nurse is planning care for a toddler who has burns over 50% total body surface area. Which of the following actions should the nurse include in the plan of care?

A. Administer enteral feedings
B. Limit intake of vitamin C
C. Limit dietary protein
D. Administer insulin prior to meals

Correct answer: A

Rationale: Administering enteral feedings is crucial for ensuring adequate nutrition and supporting healing in toddlers with extensive burns. Burns over 50% total body surface area can lead to increased metabolic demands, making it essential to provide nutrition through enteral feedings to meet the child's needs for healing and recovery. Limiting intake of vitamin C or dietary protein would be detrimental in this scenario as the child requires increased amounts of nutrients to support healing. Administering insulin prior to meals is not indicated in this case as the priority is to provide adequate nutrition to promote healing.

4. Worldwide, what is the most common nutrient deficiency?

A. magnesium deficiency
B. iron deficiency
C. selenium deficiency
D. zinc deficiency

Correct answer: B

Rationale: Iron deficiency is the most common nutrient deficiency globally. It leads to anemia and affects many populations, especially women and children. Magnesium, selenium, and zinc deficiencies are important, but they are not as prevalent as iron deficiency on a global scale.
