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. Following bariatric surgery, a patient would initially be given what type of diet?

• A. regular diet
• B. pureed diet
• C. clear liquid diet
• D. soft diet

Correct answer: C

Rationale: A clear liquid diet is typically the first step after bariatric surgery to allow the stomach to heal and prevent complications.

3. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

4. Which term is used to describe populations located in lower income, inner city, and rural areas with few supermarkets but numerous small stores stocking limited nutritious food items?

• A. Food fad
• B. Food insecurity
• C. Food desert
• D. Food patterns

Correct answer: C

Rationale: A food desert refers to areas with limited access to affordable and nutritious food, often found in lower-income urban and rural areas.

5. 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.
