A nurse is reviewing the medical record of a client who is receiving warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider?

Correct Answer: C

Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.

Correct Answer: A

Rationale: The correct answer is A: A history of gastrointestinal bleeding. Patients with a history of gastrointestinal bleeding are at increased risk of complications when taking aspirin due to its effects on platelet function and the gastrointestinal tract. Reporting this finding to the provider is crucial to ensure patient safety. Choices B, C, and D are not directly related to the increased risk associated with aspirin use in patients with a history of gastrointestinal bleeding, making them less relevant in this scenario. While monitoring platelet count and PT are important in patients taking aspirin, a history of gastrointestinal bleeding takes precedence as it directly impacts the safety and effectiveness of aspirin therapy in this client.

Correct Answer: A

Rationale: Muscle weakness is a characteristic finding in hyperkalemia. High levels of potassium can affect the normal function of muscles, leading to weakness. Nausea and increased thirst are not typically associated with hyperkalemia. Restlessness is more commonly seen in conditions such as hypoxia or anxiety, not specifically in hyperkalemia.

Correct Answer: A

Rationale: The signs of hypoglycemia include shakiness, confusion, hunger, dizziness, and lightheadedness. However, the classic and most common early sign is shakiness or tremors. When a patient is experiencing hypoglycemia, a healthcare provider should respond promptly by administering glucose to raise the blood sugar levels. Choice A is correct as it directly addresses one of the primary signs of hypoglycemia. Choices B, C, and D are incorrect because while confusion, irritability, hunger, dizziness, and lightheadedness can also be signs of hypoglycemia, shakiness or tremors are the classic and most common early symptoms that healthcare providers should be particularly vigilant for.

Correct Answer: A

Rationale: The correct nursing priority for a patient experiencing an asthma exacerbation is to administer a bronchodilator. Bronchodilators help in relieving bronchoconstriction and improving breathing. While encouraging deep breathing, providing oxygen therapy, and monitoring oxygen saturation are essential aspects of managing asthma exacerbation, the priority is to administer a bronchodilator to address the acute bronchoconstriction.
