Rationale: The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.

Correct Answer: A

Rationale: The correct answer is A: Nephrotic syndrome. Nephrotic syndrome is characterized by proteinuria (excess protein in urine), hypoalbuminemia (low serum albumin), edema (swelling due to fluid buildup), and hyperlipidemia (elevated blood lipids). These symptoms occur as a result of damage to the kidneys' filtering units. Acute kidney injury, rejection of a kidney transplant, and renal colic do not present with the same combination of symptoms as nephrotic syndrome. Acute kidney injury typically presents with a sudden decrease in kidney function, resulting in a build-up of waste products in the blood. Rejection of a kidney transplant may present with fever, pain at the transplant site, and changes in urine output. Renal colic usually presents with intense pain in the lower back or side, related to kidney stones.

Correct Answer: B

Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.

Correct Answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

Correct Answer: D

Rationale: Phytochemicals are not considered a class of nutrients. While proteins, fats, and carbohydrates are essential macronutrients providing energy and structural support, phytochemicals are non-nutrient compounds found in plants that offer various health benefits but are not essential for sustaining life like the other three choices. Therefore, the correct answer is D.
