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 client with iron deficiency anemia is being taught about dietary recommendations by a nurse. Which of the following dietary recommendations should the nurse include as a food that enhances iron absorption when consumed with nonheme iron?

• A. Tomato juice
• B. Tea
• C. Milk
• D. Dried Beans

Correct answer: A

Rationale: Tomato juice is the correct answer because it contains vitamin C, which enhances the absorption of nonheme iron. Vitamin C helps convert nonheme iron into a form that is easier for the body to absorb. Tea and milk should be avoided when consuming nonheme iron as they can inhibit iron absorption. Dried beans, although a good source of iron, do not enhance iron absorption when consumed with nonheme iron.

3. Which of the following is a normal finding during assessment of a Chest tube in a 3 way bottle system?

• A. There is a continuous bubbling in the drainage bottle
• B. There is an intermittent bubbling in the suction control bottle
• C. The water fluctuates during inhalation of the patient
• D. There is 3 cm of water left in the water seal bottle

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

5. A client with pre-dialysis end-stage kidney disease is being taught about diet. Which of the following instructions should the nurse include?

• A. Increase intake of dietary phosphorus.
• B. Eliminate foods high in protein from your diet.
• C. Reduce intake of foods high in potassium.
• D. Increase intake of sodium-containing foods.

Correct answer: C

Rationale: In pre-dialysis end-stage kidney disease, reducing intake of foods high in potassium is crucial as impaired kidney function can lead to potassium buildup in the blood, which can be dangerous. High potassium levels can cause irregular heartbeats and even cardiac arrest. Therefore, advising the client to reduce potassium-rich foods is essential to prevent complications. Choices A, B, and D are incorrect. Increasing dietary phosphorus, eliminating foods high in protein, or increasing sodium-containing foods are not appropriate recommendations for a client with pre-dialysis end-stage kidney disease as they can exacerbate the condition.
