Nursing Elites

1. Fat-soluble vitamins are different from water-soluble vitamins because the body is able to store only small amounts of fat-soluble vitamins.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: C

Rationale: The statement is correct, but the reason is not correct. A major difference between fat-soluble and water-soluble vitamins is that the body is able to store larger amounts of fat-soluble vitamins. Vitamins A and D are stored for long periods; therefore, minor shortages might not be identified until drastic depletion has occurred. Observable signs and symptoms of a dietary deficiency are often not identified until they are in an advanced state. Water-soluble vitamins, on the other hand, are not stored in the body and are excreted in the urine if taken in excess, making it harder to reach toxic levels.

2. Worldwide, what is the most common nutrient deficiency?

• A. magnesium deficiency
• B. iron deficiency
• C. selenium deficiency
• D. zinc deficiency

Correct answer: B

Rationale: Iron deficiency is the most common nutrient deficiency globally. It leads to anemia and affects many populations, especially women and children. Magnesium, selenium, and zinc deficiencies are important, but they are not as prevalent as iron deficiency on a global scale.

3. A healthcare provider is evaluating a client who reports paresthesia of the hands and feet. The provider should identify this manifestation as an indication of which of the following dietary deficiencies?

• A. Iron
• B. Riboflavin
• C. Vitamin C
• D. Vitamin B12

Correct answer: D

Rationale: Correct! Vitamin B12 deficiency can lead to neurological symptoms, including paresthesia (tingling or numbness) of the hands and feet, due to its role in nerve health. Iron deficiency is more commonly associated with anemia symptoms like fatigue and pallor. Riboflavin deficiency can cause mouth and skin changes. Vitamin C deficiency is linked to scurvy symptoms like bleeding gums and easy bruising.

4. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:

• A. 140 mm Hg and 90 mm Hg, respectively
• B. 150 mm Hg and 80 mm Hg, respectively
• C. 160 mm Hg and 110 mm Hg, respectively
• D. 180 mm Hg and 120 mm Hg, respectively

Correct answer: A

Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.

5. As the head nurse in the OR, how can you improve the effectiveness of clinical alarm systems?

• A. Limit suppliers to a few so that quality is maintained
• B. Implement a regular inventory of supplies and equipment
• C. Adherence to manufacturer’s recommendation
• D. Implement a regular maintenance and testing of alarm systems

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
