Nursing Elites

1. This vaccine content is derived from RNA recombinants.

• A. Measles C. Hepatitis B vaccines
• B. Tetanus toxoids D. DPT
• C.
• D.

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.

2. What is the desirable resting systolic blood pressure for adults?

• A. <130 mmHg>
• B. <105 mmHg>
• C. <120 mmHg>
• D. <140 mmHg>

Correct answer: C

Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.

3. 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.

4. Which food is recommended for someone with lactose intolerance?

• A. Skim milk
• B. Cheese
• C. Lactose-free yogurt
• D. Whole milk

Correct answer: C

Rationale: Lactose-free yogurt is suitable for individuals with lactose intolerance as it has reduced lactose content.

5. 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.
