Nursing Elites

1. A nurse is caring for a client with heart failure receiving digoxin. Which of the following findings should the nurse report to the provider?

• A. Heart rate 60/min.
• B. Blood pressure 110/70 mm Hg.
• C. Serum potassium 4 mEq/L.
• D. Blood pressure 120/80 mm Hg.

Correct answer: B

Rationale: The correct answer is B. A blood pressure of 110/70 mm Hg is a finding that the nurse should report to the provider when caring for a client with heart failure receiving digoxin. Digoxin can cause hypotension, so a low blood pressure reading should be reported promptly to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and would not require immediate reporting. A heart rate of 60/min is considered normal, but any further decrease should be monitored. A serum potassium level of 4 mEq/L is also within the normal range. A blood pressure of 120/80 mm Hg is typically considered normal as well.

2. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory tests should the nurse use to monitor the client's therapeutic response to the medication?

• A. INR
• B. aPTT
• C. Platelet count
• D. Hemoglobin A1C

Correct answer: A

Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.

3. A nurse in a pediatric clinic is reviewing the laboratory test results of a school-age child. Which of the following findings should the nurse report to the provider?

• A. Hgb 12.5 g/dL.
• B. Platelets 250,000/mm³.
• C. Hct 40%.
• D. WBC 14,000/mm³.

Correct answer: D

Rationale: The correct answer is D. A WBC count of 14,000/mm³ is elevated, indicating a potential infection or inflammation, and should be reported to the provider for further evaluation and management. Choices A, B, and C are within normal ranges and do not require immediate reporting as they indicate normal hemoglobin, platelet count, and hematocrit levels for a school-age child.

4. 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.

5. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?

• A. PaO2 of 95 mm Hg
• B. PaCO2 of 55 mm Hg
• C. HCO3 of 24 mEq/L
• D. pH level of 7.35

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.
