1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value is most concerning?
- A. Serum glucose of 300 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: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.
2. 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.
3. A client with hyperthyroidism is admitted to the postoperative unit after subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?
- A. Total calcium 5.0 mg/dL.
- B. Serum sodium 140 mEq/L.
- C. Serum potassium 4.0 mEq/L.
- D. Serum glucose 90 mg/dL.
Correct answer: A
Rationale: The correct answer is A. A calcium level of 5.0 mg/dL is critically low and could indicate hypoparathyroidism, a possible complication after thyroidectomy. Low calcium levels can lead to tetany, seizures, and cardiac dysrhythmias, requiring immediate intervention. Choices B, C, and D fall within the normal range and do not require immediate intervention in this scenario.
4. The healthcare provider is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which clinical finding is most concerning?
- A. Increased fatigue
- B. Elevated blood pressure
- C. Elevated hemoglobin
- D. Low urine output
Correct answer: B
Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure is the most concerning finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention to prevent further damage to the kidneys and other organs. Increased fatigue (choice A) is a common symptom in CKD but may not be as acutely concerning as elevated blood pressure. Elevated hemoglobin (choice C) can be an expected outcome of erythropoietin therapy and is not necessarily concerning. Low urine output (choice D) is important to monitor in CKD but may not be as immediately concerning as elevated blood pressure in this context.
5. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?
- A. Peaked T waves on the ECG
- B. Bradycardia
- C. Muscle weakness
- D. Decreased deep tendon reflexes
Correct answer: A
Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.
