Nursing Elites

1. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

2. A client with dyspnea is being admitted to the medical unit. To best prepare for the client's arrival, the nurse should ensure that the client's bed is in which position?

• A. Trendelenburg
• B. Supine
• C. Prone
• D. Fowler's

Correct answer: D

Rationale: Fowler's position (head elevated at 45-60 degrees) improves oxygenation by expanding the lungs, making it the best position for clients with dyspnea. Supine or prone positions restrict lung expansion, and Trendelenburg position (head down) can exacerbate breathing difficulties by increasing pressure on the lungs and diaphragm.

3. 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.

4. A client with chronic kidney disease is admitted with complaints of fatigue and swelling in the lower extremities. What laboratory finding is most important for the nurse to report?

• A. Serum creatinine level of 2.0 mg/dL.
• B. Hemoglobin level of 8 g/dL.
• C. Potassium level of 5.6 mEq/L.
• D. Blood urea nitrogen (BUN) level of 25 mg/dL.

Correct answer: B

Rationale: The correct answer is B. A hemoglobin level of 8 g/dL suggests anemia, which commonly occurs in clients with chronic kidney disease and requires prompt intervention. Reporting this finding is crucial to address the anemic condition. Choices A, C, and D are important in the context of chronic kidney disease but do not directly relate to the symptoms of fatigue and swelling in the lower extremities described in the scenario.

5. A client with a head injury reports severe nausea. What is the nurse's priority action?

• A. Administer anti-nausea medication as prescribed.
• B. Prepare the client for a CT scan.
• C. Elevate the head of the bed and provide an emesis basin.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: Severe nausea in a client with a head injury may be a sign of increased intracranial pressure. The nurse should notify the healthcare provider immediately to ensure timely intervention, as increased pressure can lead to further complications such as brain herniation. Administering anti-nausea medication or preparing for a CT scan may delay necessary treatment for the underlying cause of the nausea, which could be related to the head injury. Elevating the head of the bed and providing an emesis basin may help manage symptoms but should not be the priority over addressing the potential increase in intracranial pressure.
