Nursing Elites

1. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

2. A client with a history of 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 B: Administer intravenous insulin and glucose. In the presence of hyperkalemia, the priority intervention is to shift potassium back into the cells to lower serum levels. Insulin, in combination with glucose, helps drive potassium intracellularly. Administering calcium gluconate (choice A) is used to stabilize myocardial cell membranes but does not address the underlying cause of hyperkalemia. Administering sodium bicarbonate (choice C) is not the initial treatment for hyperkalemia. Loop diuretics (choice D) may be used later to enhance potassium excretion but are not the primary intervention for acute hyperkalemia.

3. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning to the nurse?

• A. Serum glucose of 500 mg/dL
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS) as it indicates severe dehydration and hypertonicity. This high serum osmolarity level can lead to neurological complications and requires immediate intervention to prevent further deterioration. Serum glucose levels, blood pressure, and serum pH are important parameters to monitor in HHS, but a significantly elevated serum osmolarity poses a higher risk of complications and warrants urgent attention. High serum glucose levels, like 500 mg/dL, are expected in HHS but do not directly indicate the severity of dehydration. Blood pressure of 140/90 mmHg is within normal limits and may not be directly related to the acute complications of HHS. A serum pH of 7.30 suggests acidosis, which is important to address but may not be as immediately concerning as severe dehydration indicated by high serum osmolarity.

4. A female client with ovarian cancer is receiving chemotherapy. Which laboratory result should the nurse report to the healthcare provider immediately?

• A. White blood cell count of 2,000/mm³
• B. Platelet count of 100,000/mm³
• C. Hemoglobin level of 10 g/dL
• D. Serum creatinine level of 1.5 mg/dL

Correct answer: A

Rationale: A white blood cell count of 2,000/mm³ is critically low and places the client at high risk for infection, requiring immediate intervention. Neutropenia, a low white blood cell count, is a common side effect of chemotherapy. A decreased white blood cell count compromises the immune system's ability to fight infections, making it a priority to address to prevent serious complications. Platelet count of 100,000/mm³ is relatively low but not as urgent as a severely low white blood cell count. Hemoglobin level of 10 g/dL is within the normal range for females and does not require immediate intervention. Serum creatinine level of 1.5 mg/dL is also within the normal range and does not pose an immediate threat to the client's health.

5. After a sudden loss of consciousness, a female client is taken to the ED, and the initial assessment indicates that her blood glucose level is critically low. Once her glucose level is stabilized, the client reports that she was recently diagnosed with anorexia nervosa and is being treated at an outpatient clinic. Which intervention is most important to include in this client's discharge plan?

• A. Describe the signs and symptoms of hypoglycemia.
• B. Encourage a low-carbohydrate and high-protein diet.
• C. Reinforce the need to continue outpatient treatment.
• D. Suggest wearing a medical alert bracelet at all times.

Correct answer: B

Rationale: Encouraging a low-carbohydrate and high-protein diet is crucial for a client recovering from anorexia nervosa to prevent hypoglycemic episodes. Choice A is not the most important intervention at this point since the client is already aware of hypoglycemia based on the recent event. Choice C is important but not the priority in this situation where dietary intervention is crucial. Choice D, suggesting a medical alert bracelet, is not as essential as ensuring proper nutrition to prevent further hypoglycemic episodes.
