Nursing Elites

1. Which cells in the islet of the pancreas are responsible for synthesizing insulin?

• A. Alpha cells
• B. Beta cells
• C. Gamma cells
• D. Delta cells

Correct answer: B

Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.

2. A nurse is caring for an antepartum client who has iron-deficiency anemia. When teaching the client about nutrition, the nurse should emphasize the need for an increased intake of which of the following foods?

• A. Milk and cheese
• B. Red meat and organ meat
• C. Fresh fruits
• D. Whole grain breads

Correct answer: B

Rationale: The correct answer is red meat and organ meat. These foods are rich sources of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Red meat and organ meat can significantly help in increasing the iron levels in individuals with iron-deficiency anemia, especially in antepartum clients. Fresh fruits, while nutritious, do not provide high amounts of iron. Milk and cheese are not the best sources of iron for individuals with iron-deficiency anemia. Whole grain breads also do not contain as much bioavailable iron as red meat and organ meat.

3. What health instruction will enhance regulation of a colostomy (defecation) of clients?

• A. Irrigate after lunch everyday
• B. Eat fruits and vegetables in all three meals
• C. Eat balanced meals at regular intervals
• D. Restrict exercise to walking only

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. To successfully complete the tasks of older adulthood, an 85 year old who has been a widow for 25 years should be encouraged to:

• A. Invest her creative energies in promoting social welfare
• B. Redefine her role in the society and offer something and offer something of value
• C. Feel a sense of satisfaction in reflecting on her productive life
• D. Look to recapture the opportunities that were never started or completed

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. A nurse is educating a group of older adults in a community center on weight management using the BMI scale. Using the client's height and weight to calculate BMI, which of the following clients has a healthy BMI?

• A. A client with a weight of 128 lb and height of 70 inches
• B. A client with a weight of 150 lb and height of 68 inches
• C. A client with a weight of 200 lb and height of 72 inches
• D. A client with a weight of 133 lb and height of 60 inches

Correct answer: A

Rationale: To determine a healthy BMI, we need to calculate it using the formula: BMI = weight (lbs) / height^2 (inches) x 703. For choice A, BMI = 128 / (70 x 70) x 703 = 18.38, which falls within the healthy BMI range of 18.5-24.9. Therefore, choice A is correct. Choices B, C, and D have BMIs of 22.8, 27.1, and 26.1, respectively, which are outside the healthy range. Thus, choices B, C, and D are incorrect.
