Nursing Elites

1. 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.

2. 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.

3. Mrs. Pichay who is for thoracentesis is assigned by the nurse to any of the following positions, EXCEPT:

• A. straddling a chair with arms and head resting on the back of the chair
• B. lying on the unaffected side with the bed elevated 30-40 degrees
• C. lying prone with the head of the bed lowered 15-30 degrees
• D. sitting on the edge of the bed with her feet supported and arms and head on a padded overhead table

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.

• 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

5. Which of the following is a poor food source of iron?

• A. Dried fruits
• B. Cheese
• C. Clams
• D. Legumes

Correct answer: B

Rationale: Iron is an essential nutrient for the body, and while it can be found in many different types of foods, the amounts can vary significantly. Cheese, while a good source of other nutrients like calcium and protein, is not a particularly rich source of iron. On the other hand, clams, legumes, and dried fruits are known to contain higher levels of iron. Therefore, among the provided choices, cheese is considered a poor source of iron. It's important to note that a balanced diet should include a variety of foods to ensure the intake of all necessary nutrients.
