Question 1 of 5
A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?
Correct Answer: D
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.
Question 2 of 5
The client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value is most concerning?
Correct Answer: A
Rationale: A serum potassium level of 6.0 mEq/L is most concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications such as arrhythmias and cardiac arrest. Immediate intervention is required to lower potassium levels. Choice B, serum creatinine of 2.5 mg/dL, is elevated but expected in ESRD due to impaired kidney function. Choice C, serum calcium of 8.0 mg/dL, is within the normal range and not typically a priority in this situation. Choice D, hemoglobin of 10 g/dL, is slightly low but not an immediate concern for a client scheduled for hemodialysis unless significantly lower and causing severe symptoms.
Question 3 of 5
A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?
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.
Question 4 of 5
A client with a history of chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
Correct Answer: A
Rationale: The correct answer is A: Serum potassium level. In a client receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increased demand for potassium. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because erythropoietin therapy specifically impacts potassium levels, not white blood cell count, hemoglobin level, or serum calcium level.
Question 5 of 5
A client with cirrhosis is admitted with ascites and jaundice. Which clinical finding is most concerning?
Correct Answer: C
Rationale: The correct answer is C. Confusion and altered mental status are the most concerning clinical findings in a client with cirrhosis because they may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Peripheral edema (choice A) and increased abdominal girth (choice B) are common manifestations of cirrhosis but are not as acutely concerning as signs of hepatic encephalopathy. Yellowing of the skin (choice D) is due to jaundice, which is already present in the client and does not directly indicate a worsening condition like confusion and altered mental status.
