1. Which two dietary components may help decrease blood cholesterol levels?

• A. Omega-3 fatty acids and soluble fiber
• B. Short-chain fatty acids and insoluble fiber
• C. Trans fatty acids and potassium
• D. Cis fatty acids and calcium

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

2. What is the initial major sign of acute renal failure?

• A. Oliguria
• B. Hematuria
• C. Proteinuria
• D. Glycosuria

Correct answer: A

Rationale: Oliguria, or reduced urine output, is often the initial major sign of acute renal failure. This reduction in urine output indicates that the kidneys are not functioning properly. Hematuria (blood in urine), proteinuria (presence of protein in urine), and glycosuria (presence of glucose in urine) are not typically the initial major signs of acute renal failure. While they may be present in certain conditions, oliguria is the most common and critical indicator of acute renal failure.

3. Knowing that for a comatose patient hearing is the last sense to be lost, as Judy’s nurse, what should you do?

• A. Tell her family that probably she can’t hear them
• B. Talk loudly so that Wendy can hear you
• C. Tell her family who are in the room not to talk
• D. Speak softly then hold her hands gently

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.

4. Which vitamin's recommended dietary allowance (RDA) is significantly increased during pregnancy?

• A. Folate
• B. Thiamine (B1)
• C. Riboflavin (B2)
• D. Niacin (B3)

Correct answer: A

Rationale: The correct answer is A: Folate. During pregnancy, the recommended dietary allowance (RDA) for folate is significantly increased to support fetal development and prevent neural tube defects and other congenital anomalies. Folate plays a crucial role in DNA synthesis and cell growth, making it essential for the rapidly dividing cells of the developing fetus. Thiamine (B1), Riboflavin (B2), and Niacin (B3) are important vitamins, but their RDAs do not undergo as significant an increase during pregnancy as folate's RDA does.

5. Each statement is true of water-soluble vitamins, except one. Which is it?

• A. Act as coenzymes
• B. Deficiencies develop rapidly
• C. Daily intake is necessary
• D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.
