Nursing Elites

1. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be elevated?

• A. Serum albumin.
• B. Ammonia.
• C. Bilirubin.
• D. Prothrombin time.

Correct answer: B

Rationale: The correct answer is B: Ammonia. In clients with cirrhosis, impaired liver function can lead to elevated levels of ammonia in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a condition characterized by altered mental status. Serum albumin (Choice A) is typically decreased in cirrhosis due to the liver's reduced synthetic function. Bilirubin (Choice C) levels can be elevated in liver disease but may not always be the most specific marker for cirrhosis. Prothrombin time (Choice D) is prolonged in cirrhosis due to impaired liver synthesis of clotting factors.

2. Which electrolyte imbalance should be closely monitored in patients on diuretics?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Patients on diuretics are at risk of developing hypokalemia due to increased potassium excretion by the kidneys. Hypokalemia can lead to serious consequences such as cardiac arrhythmias. Hyponatremia (choice B) is an imbalance of sodium levels and is not typically associated with diuretic use. Hyperkalemia (choice C) is the opposite condition where potassium levels are elevated and is less common in patients on diuretics. Hypercalcemia (choice D) is an excess of calcium in the blood and is not directly related to diuretic use. Therefore, monitoring for hypokalemia is crucial in patients taking diuretics.

3. A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?

• A. aPTT 75 seconds.
• B. INR 1.2.
• C. Hemoglobin 10 g/dL.
• D. Fibrinogen level 350 mg/dL.

Correct answer: A

Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.

4. A healthcare professional is reviewing the medical record of a client with schizophrenia. Which of the following findings should the professional report to the provider?

• A. Blood pressure: 102/56 mm Hg.
• B. Heart rate: 95/min.
• C. Sore throat.
• D. WBC count 14,000/mm^3.

Correct answer: D

Rationale: An elevated WBC count should be reported to the provider as it may indicate an infection. Elevated white blood cell counts can be a sign of an underlying infection or inflammation. Monitoring and reporting abnormal laboratory values are essential for timely interventions. The other options, such as blood pressure, heart rate, and a sore throat, while important for overall assessment, are not directly related to the potential medical urgency indicated by an elevated WBC count.

5. Which lab value is critical for patients on warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor sodium levels
• D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.
