Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?

• A. INR of 2.5.
• B. PTT of 45 seconds.
• C. Hemoglobin of 12 g/dL.
• D. Platelet count of 150,000/mm³.

Correct answer: A

Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.

2. A patient with rheumatoid arthritis is taking prednisone. What is an important side effect for the nurse to monitor?

• A. Hyperglycemia
• B. Bradycardia
• C. Hypotension
• D. Hyperkalemia

Correct answer: A

Rationale: The correct answer is hyperglycemia. Prednisone, a corticosteroid, can lead to elevated blood sugar levels as a side effect, particularly in patients with diabetes or those predisposed to developing diabetes. Monitoring for hyperglycemia is crucial to prevent complications like diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome.

3. A client with heart failure is receiving digoxin (Lanoxin). Which finding indicates that the medication is effective?

• A. Increased heart rate.
• B. Decreased pedal edema.
• C. Elevated blood pressure.
• D. Improved urine output.

Correct answer: B

Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.

4. Which client's laboratory value requires immediate intervention by a nurse?

• A. A client with GI bleeding who is receiving a blood transfusion and has a hemoglobin of 7 grams.
• B. A client with pancreatitis who has a fasting glucose of 190 mg/dl today and had 160 mg/dl yesterday.
• C. A client with hepatitis who is jaundiced and has a bilirubin level that is 4 times the normal value.
• D. A client with cancer who has an absolute neutrophil count < 500 today and had 2,000 yesterday.

Correct answer: D

Rationale: The correct answer is D. A sudden drop in neutrophil count to below 500 indicates severe neutropenia, putting the client at high risk for infections. Neutrophils are essential for fighting off infections, and a significant decrease in their count can compromise the client's immune response. Immediate intervention is necessary to prevent the development of serious infections in the client with neutropenia.

5. A client with a history of diabetes mellitus presents with confusion, sweating, and palpitations. What should the nurse do first?

• A. Check the client's blood glucose level.
• B. Administer 10 units of insulin.
• C. Give the client a high-protein snack.
• D. Measure the client's blood pressure.

Correct answer: A

Rationale: The correct first action for a client presenting with confusion, sweating, and palpitations, suggestive of hypoglycemia, is to check the client's blood glucose level. This step helps to confirm if the symptoms are due to low blood sugar levels and guides appropriate interventions. Administering insulin without knowing the current blood glucose level can be dangerous and is not recommended as the initial step. Offering a high-protein snack may be necessary after confirming hypoglycemia, but checking the blood glucose level takes precedence. Measuring blood pressure is not the priority in this situation; addressing hypoglycemia is the immediate concern.
