Nursing Elites

1. Which ethnic group has the lowest rates of type 2 diabetes?

• A. Caucasians
• B. Asian Indians
• C. Pacific Islanders
• D. African Americans

Correct answer: A

Rationale: Statistical data suggest that Caucasians generally have lower rates of type 2 diabetes compared to the other ethnic groups listed in the choices. This is not to say that Caucasians are immune to the disease, but rather that they have fewer reported instances. On the other hand, African Americans and Pacific Islanders are often identified as groups with a significantly higher risk and prevalence of type 2 diabetes. Asian Indians also exhibit higher rates compared to Caucasians. It is important to note that these are general trends observed in statistical data, and individual health outcomes can vary based on various factors such as lifestyle, diet, and genetics, among others. Therefore, the correct answer is A: Caucasians because they generally have the lowest rates of type 2 diabetes when compared to the other ethnic groups mentioned.

2. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.

3. Which nutrient is most important for maintaining fluid balance in the body?

• A. Protein
• B. Sodium
• C. Calcium
• D. Vitamin C

Correct answer: B

Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.

4. What nursing diagnosis would be most appropriate for a patient with heart failure?

• A. risk for infection
• B. fluid volume excess
• C. impaired body temperature
• D. ineffective airway clearance

Correct answer: B

Rationale: The most appropriate nursing diagnosis for a patient with heart failure is 'fluid volume excess.' In heart failure, the heart's reduced pumping ability leads to fluid retention, causing an excess of fluid in the body. This can result in symptoms such as edema, shortness of breath, and weight gain. 'Risk for infection,' 'impaired body temperature,' and 'ineffective airway clearance' are not the most appropriate nursing diagnoses for a patient with heart failure as they do not directly relate to the pathophysiology and common issues seen in heart failure patients.

5. Intrinsic factor from the stomach is needed for the absorption of which vitamin?

• A. vitamin B12
• B. folate
• C. niacin
• D. vitamin B6

Correct answer: A

Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.
