1. What does oliguria lead to in patients with acute kidney injury?

• A. Hypophosphatemia and overgrowth of bone tissue
• B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
• C. Sodium retention and elevated levels of potassium
• D. Edema due to increased urine production

Correct answer: C

Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.

2. Men generally have a higher RDA than women, except during pregnancy and lactation when women’s nutritional needs increase significantly.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is TRUE. Men typically require a higher Recommended Dietary Allowance (RDA) than women due to physiological differences. However, during pregnancy and lactation, women's nutritional needs increase significantly to support the growth and development of the baby. Therefore, during these stages, women may require a higher RDA compared to men. This exception is crucial to consider when evaluating nutritional requirements based on gender.

3. Each statement is true of rickets, except one. Which is the exception?

• A. Rickets is being diagnosed more frequently in the United States.
• B. Rickets is caused by vitamin C deficiency.
• C. Tachetic deformities such as bow legs or knock-knees develop.
• D. A narrow and distorted chest occurs.

Correct answer: B

Rationale: Rickets is caused by vitamin D deficiency, not vitamin C deficiency. It usually occurs in children who are 1 to 3 years old. The name rickets came from the word 'wrikken,' meaning 'to bend or twist.' Common manifestations of rickets include tachetic deformities like bow legs or knock-knees, a narrow and distorted chest, and failure of the epiphyses of bones to develop normally, resulting in twisted and warped bones. While the diagnosis of rickets may be increasing in the United States, it is not caused by a lack of vitamin C.

4. Which foods increase iron absorption when consumed with nonheme iron? (SATA)

• A. Kiwi
• B. Strawberries
• C. Coffee
• D. A, B

Correct answer: D

Rationale: Kiwi and strawberries are high in vitamin C, which increases iron absorption.

5. 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.
