Nursing Elites

1. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

• A. Serum glucose of 300 mg/dL
• B. Serum potassium of 4.5 mEq/L
• C. Serum bicarbonate of 15 mEq/L
• D. Serum pH of 7.28

Correct answer: D

Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.

2. A client with peptic ulcer disease is being taught about lifestyle modifications by a nurse. Which client statement indicates a need for further teaching?

• A. ‘I should avoid drinking alcohol to prevent irritation of my ulcer.’
• B. ‘I should take my antacids regularly, even if I don’t have symptoms.’
• C. ‘I should avoid eating spicy foods to prevent irritation of my ulcer.’
• D. ‘I should limit my caffeine intake to prevent irritation of my ulcer.’

Correct answer: B

Rationale: The statement ‘I should take my antacids regularly, even if I don’t have symptoms’ indicates a misunderstanding. Antacids should only be taken when symptoms are present to neutralize excess stomach acid. Taking antacids regularly when not experiencing symptoms may lead to metabolic alkalosis. Choices A, C, and D are correct statements for a client with peptic ulcer disease as they all focus on avoiding irritants that can exacerbate the condition.

3. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

4. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.

5. A client with chronic renal failure (CRF) is placed on a protein-restricted diet. Which nutritional goal supports this dietary change?

• A. Reduce production of urea nitrogen (BUN)
• B. Decrease the risk of hyperkalemia
• C. Promote healing of injured nephrons
• D. Promote the elimination of albumin

Correct answer: A

Rationale: The correct answer is A: Reduce production of urea nitrogen (BUN). A protein-restricted diet is essential for clients with chronic renal failure to decrease the production of urea nitrogen, as the kidneys cannot effectively excrete it. This helps in managing the accumulation of waste products in the body. Choices B, C, and D are incorrect. Choice B is not directly related to a protein-restricted diet but focuses on managing potassium levels. Choice C is not a direct nutritional goal of a protein-restricted diet but aims at supporting kidney function. Choice D is not a target of a protein-restricted diet but relates more to managing protein loss in the urine.
