1. Which nutrient is most closely associated with the prevention of neural tube defects in a developing fetus for a woman planning to become pregnant?

Correct answer: B

Rationale: The correct answer is folate. Folate, also known as Vitamin B9, is vital for the prevention of neural tube defects in the developing fetus. It is primarily responsible for the creation and repair of DNA, which is essential during rapid growth stages such as pregnancy. While nutrients like calcium, vitamin A, and choline are important for pregnancy, they are not as directly linked to preventing neural tube defects as folate. Calcium is crucial for the baby's bone and teeth development. Vitamin A is essential for vision, immune function, and cellular growth. Choline supports brain development and neural functioning. However, none of these nutrients have the same direct impact on preventing neural tube defects as folate.

2. Mang Carlos has a standing DNR order. He then suddenly stopped breathing and you are at his bedside. You would:

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.

3. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

4. What is the most common type of kidney stone?

Correct answer: B

Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.

5. Match the energy-yielding nutrient to the amount of energy it provides to the body: Carbs, Fats, Proteins.

Correct answer: D

Rationale: The correct answer is D, All of the above. Carbohydrates and proteins provide 4 kcal per gram, while fats provide 9 kcal per gram. Therefore, all three energy-yielding nutrients provide different amounts of energy to the body. Choice A, B, and C are incorrect because each of them individually provides a specific amount of energy per gram, but when considering all nutrients together, they collectively cover the spectrum of energy provision to the body.
