Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

2. A healthcare provider is assessing a client with a history of hypertension who is currently taking a diuretic. Which assessment finding is most important to report to the healthcare provider?

• A. Potassium level of 3.2 mEq/L
• B. Blood pressure of 148/90 mmHg
• C. Pulse rate of 62 beats per minute
• D. Blood glucose level of 130 mg/dl

Correct answer: A

Rationale: A potassium level of 3.2 mEq/L is low and places the client at risk for cardiac arrhythmias, requiring immediate intervention. Hypokalemia can result from diuretic use and can lead to serious complications such as irregular heart rhythms. Monitoring and correcting potassium levels are crucial in preventing adverse cardiac events. The other options, though important, do not pose an immediate life-threatening risk compared to the low potassium level.

3. A 3-year-old boy with a congenital heart defect is brought to the clinic by his mother. During the assessment, the mother asks the nurse why her child is at the 5th percentile for growth. What response is best for the nurse to provide?

• A. Does your child seem mentally slower than his peers also?
• B. His smaller size is probably due to the heart disease
• C. Haven't you been feeding him according to recommended daily allowances for children?
• D. You should not worry about the growth tables. They are only averages for children

Correct answer: B

Rationale: Heart disease can affect growth, leading to smaller size in children.

4. A client with cirrhosis is admitted with ascites and jaundice. Which assessment finding is most concerning?

• A. Peripheral edema
• B. Confusion and altered mental status
• C. Increased abdominal girth
• D. Yellowing of the skin

Correct answer: B

Rationale: Confusion and altered mental status are concerning signs of hepatic encephalopathy in a client with cirrhosis. Hepatic encephalopathy is a serious complication of liver disease that requires immediate intervention. Peripheral edema may be present due to fluid accumulation, increased abdominal girth can indicate ascites which is common in cirrhosis, and yellowing of the skin is a typical manifestation of jaundice in liver dysfunction, all of which are important but not as immediately concerning as signs of hepatic encephalopathy.

5. 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.
