Nursing Elites

1. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

• A. Spinach
• B. Cantaloupe
• C. Chicken
• D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.

2. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.

3. Why is bleeding in the leg of a pregnant woman considered as an emergency?

• A. Blood volume is greater in pregnant woman; therefore, blood loss is increased
• B. There is an increase blood pressure during pregnancy increasing the likelihood of hemorrhage
• C. Pregnant woman are anemic, all forms of blood loss should be considered as an emergency especially if it is in the
• D. The pressure of the gravid uterus will exert additional force thus, increasing the blood loss in the lower extremities

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. The nurse notes that the fall might also cause a possible head injury. The patient will be observed for signs of increased intracranial pressure which include:

• A. Narrowing of the pulse pressure
• B. Vomiting
• C. Periorbital edema
• D. A positive Kernig's sign

Correct answer: C

Rationale: Periorbital edema is a sign of increased intracranial pressure. It is caused by fluid accumulation around the eyes due to compromised drainage. Narrowing of the pulse pressure is more indicative of shock than increased intracranial pressure. While vomiting can be a sign of increased intracranial pressure, it is not as specific as periorbital edema. A positive Kernig's sign is associated with meningitis, not increased intracranial pressure.

5. Proteolytic enzymes are most likely to break down which food type?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.
