A nurse is teaching a client who has heart failure about fluid restrictions. Which of the following instructions should the nurse include?

Correct Answer: B

Rationale: The correct answer is B: 'Limit fluid intake to 1-2 liters per day.' For clients with heart failure, fluid restriction is essential to prevent fluid overload. Restricting fluid intake to 1-2 liters per day helps maintain fluid balance and prevents exacerbation of heart failure symptoms. Choices A, C, and D are incorrect because consuming 3 liters, 4 liters, or limiting water intake to 1 liter per day, respectively, can lead to fluid overload in clients with heart failure.

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: D

Rationale: The correct instruction is to use the peak flow meter after using the rescue inhaler. This ensures accurate monitoring of asthma control during symptoms. Choice A is incorrect because peak flow measurements should be done before taking medications. Choice B is incorrect as the client should blow into the meter quickly and forcefully to get an accurate reading. Choice C is also incorrect as peak flow should be measured regularly, not just when feeling short of breath.

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.
