Nursing Elites

1. Nutrients that may help decrease high blood pressure levels include:

• A. magnesium and sodium
• B. protein and monounsaturated fat
• C. calcium and potassium
• D. dietary fiber and plant sterols

Correct answer: C

Rationale: Calcium and potassium play vital roles in regulating blood pressure, with potassium helping to balance the negative effects of sodium.

2. Cancers that arise from epithelial tissues are known as:

• A. Leukemias
• B. Myelomas
• C. Carcinomas
• D. Sarcomas

Correct answer: C

Rationale: The correct answer is C: Carcinomas. Carcinomas are cancers that originate from epithelial tissues, which are the tissues lining the surfaces of organs and structures in the body. Leukemias (choice A) are cancers of the blood-forming cells, not epithelial tissues. Myelomas (choice B) are cancers that develop in plasma cells in the bone marrow, not epithelial tissues. Sarcomas (choice D) are cancers that arise from connective tissues like bone, cartilage, or muscle, not epithelial tissues. Therefore, choices A, B, and D are incorrect in the context of cancers originating from epithelial tissues.

3. A factor contributing to the risk for dehydration in the older adult is that _____.

• A. drinking fluids causes loss of bladder control
• B. older adults do not seem to notice mouth dryness as readily as younger people
• C. increased fluid intake will decrease the intake of nutrient-dense foods
• D. changes in intestinal motility contribute to excess fluid loss

Correct answer: C

Rationale: Older adults may not notice mouth dryness as readily as younger individuals, increasing their risk for dehydration, especially if they do not consciously increase fluid intake.

4. What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?

• A. Prevent mediastinal shift
• B. Promote chest expansion of the remaining lung
• C. Drain fluids and blood accumulated post-operatively
• D. Remove the air in the lungs to promote lung expansion

Correct answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.

5. A nurse is instructing a group of clients regarding calcium-rich foods. Which of the following foods should the nurse include in the teaching as the best source of calcium?

• A. 1?2 cup ice cream
• B. 1 ounce Swiss cheese
• C. 1 cup milk
• D. 1 cup cottage cheese

Correct answer: D

Rationale: Cottage cheese is the best source of calcium among the options provided. It is rich in calcium and provides a significant amount per serving. 1 cup of cottage cheese contains more calcium compared to 1?2 cup of ice cream, 1 ounce of Swiss cheese, or 1 cup of milk. Ice cream is not a significant source of calcium and is often high in sugar and fat. Swiss cheese and milk contain calcium, but cottage cheese has a higher calcium content per serving, making it the best choice for meeting calcium needs.
