Question 1 of 5
A client with chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?
Correct Answer: A
Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.
Question 2 of 5
A client with cirrhosis is admitted with jaundice and ascites. Which assessment finding is most concerning?
Correct Answer: C
Rationale: In a client with cirrhosis presenting with jaundice and ascites, yellowing of the skin (icterus) is the most concerning assessment finding. This indicates significant liver dysfunction and a high level of bilirubin in the blood. Yellowing of the skin suggests a severe impairment of the liver's ability to process bilirubin, which can lead to serious complications. Peripheral edema and increased abdominal girth are common manifestations of cirrhosis but are not as acutely concerning as skin yellowing. Confusion and altered mental status are also critical findings in cirrhosis, indicating hepatic encephalopathy, but skin yellowing is more closely associated with the severity of liver dysfunction in this scenario.
Question 3 of 5
The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
Correct Answer: A
Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease (CKD) is receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can stimulate red blood cell production, leading to an increased demand for potassium. This increases the risk of hyperkalemia, making it crucial to monitor potassium levels closely. Choices B, C, and D are incorrect because erythropoietin therapy primarily affects red blood cell production, not hemoglobin, white blood cell count, or serum calcium levels.
Question 4 of 5
The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?
Correct Answer: C
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.
Question 5 of 5
The nurse is caring for a client with a chest tube following a pneumothorax. Which finding requires immediate intervention?
Correct Answer: C
Rationale: Subcutaneous emphysema is the most critical finding requiring immediate intervention in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, which can lead to respiratory compromise. Oxygen saturation of 94% is slightly low but may not require immediate intervention. Crepitus around the insertion site can be a normal finding post-procedure. Drainage of 50 ml per hour is within the expected range for a chest tube output and does not indicate an immediate concern.
