Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. The nurse is teaching a client about lifestyle changes to manage hypertension. Which of the following should be emphasized?

• A. Increase daily intake of sodium.
• B. Exercise regularly and maintain a healthy weight.
• C. Reduce intake of potassium-rich foods.
• D. Drink alcohol in moderation.

Correct answer: B

Rationale: The correct answer is B. Regular exercise and maintaining a healthy weight are crucial lifestyle changes in managing hypertension. Exercise helps lower blood pressure and improves heart health, while maintaining a healthy weight reduces the risk of hypertension. Choices A, C, and D are incorrect. Increasing daily intake of sodium can elevate blood pressure, reducing intake of potassium-rich foods is not recommended as potassium helps lower blood pressure, and drinking alcohol should be limited or avoided as it can raise blood pressure.

3. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?

• A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
• B. The antagonistic interaction of the medications has reduced their effectiveness.
• C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
• D. The additive effect of the medications has lowered the blood pressure too much.

Correct answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

4. A child newly diagnosed with sickle cell anemia (SCA) is being discharged from the hospital. Which information is most important for the nurse to provide the parents prior to discharge?

• A. Nutritional guidelines to support blood health
• B. Signs of infection to monitor for
• C. When to give pain medication
• D. Instructions about how much fluid the child should drink daily

Correct answer: D

Rationale: Proper hydration is crucial in managing sickle cell anemia (SCA) as it helps prevent sickling of red blood cells and reduces blood viscosity, which can lead to painful crises. Ensuring the child drinks enough fluids is essential to maintain adequate hydration levels and reduce the risk of complications. While nutritional guidelines and recognizing signs of infection are important aspects of care, maintaining proper hydration is the most immediate and critical factor in managing SCA and preventing crises.

5. While providing home care to a client with congestive heart failure, the nurse is asked how long diuretics must be taken. What is the nurse’s best response?

• A. As you urinate more, you will need less medication to control fluid.
• B. You will have to take this medication for about a year.
• C. The medication must be continued so the fluid problem is controlled.
• D. Please talk to your health care provider about medications and treatments.

Correct answer: C

Rationale: Diuretics must be continued as long as the fluid problem persists to prevent heart failure symptoms.
