A client with a history of heart failure is prescribed furosemide. Which assessment finding indicates the medication is effective?
Increased urine output
Elevated blood pressure
Increased heart rate
Weight gain
The Correct Answer is A
Choice A reason: Furosemide, a loop diuretic, promotes urine output by inhibiting sodium reabsorption in the kidneys, reducing fluid overload in heart failure. Increased urine output indicates effective diuresis, alleviating pulmonary and peripheral edema, making it the primary sign of therapeutic efficacy.
Choice B reason: Elevated blood pressure is not an expected effect of furosemide, which reduces preload and blood volume, often lowering pressure. Effective diuresis is shown by increased urine output, as this directly reflects fluid removal, critical for heart failure management.
Choice C reason: Increased heart rate is not a direct indicator of furosemide efficacy. Diuresis reduces cardiac workload, potentially stabilizing heart rate, but urine output is the primary measure, as it confirms fluid excretion, the medication’s main action in heart failure.
Choice D reason: Weight gain indicates fluid retention, the opposite of furosemide’s goal. Effective diuresis causes weight loss due to fluid excretion. Increased urine output is the key sign, as it directly measures the diuretic’s action in reducing heart failure-related fluid overload.

Correct Answer is B
Explanation
Choice A reason: Arterial blood gases assess oxygenation and acid-base balance, critical for diagnosing respiratory distress severity. However, this diagnostic measure does not immediately relieve airway obstruction. Clearing secretions is prioritized to restore ventilation, as hypoxia can rapidly cause tissue damage or cardiac arrest in acute respiratory distress.
Choice B reason: Suctioning removes airway secretions, directly addressing breathing difficulty. Secretions obstruct airways, reducing oxygen delivery to alveoli and impairing gas exchange. Immediate suctioning restores patency, enhances ventilation, and prevents hypoxia, making it the priority intervention to stabilize the client’s respiratory function in acute distress.
Choice C reason: PRN analgesia addresses pain, which is not indicated as the primary issue. Pain relief does not resolve airway obstruction or improve breathing. Administering analgesia prematurely could mask respiratory symptoms, delaying critical airway management and potentially worsening hypoxia by neglecting the underlying obstruction.
Choice D reason: An antipyretic reduces fever, improving comfort but not addressing breathing difficulty. Fever is secondary, and treating it does not restore airway patency or oxygenation. Airway management is prioritized in respiratory distress to prevent hypoxia and ensure effective gas exchange before managing fever symptoms.
Correct Answer is B
Explanation
Choice A reason: Platelet count assesses bleeding risk but does not measure warfarin’s anticoagulant effect. Warfarin inhibits clotting factors, monitored by INR. Platelet counts are relevant for antiplatelet drugs, not anticoagulants, making INR the priority for evaluating warfarin efficacy in atrial fibrillation.
Choice B reason: INR measures warfarin’s anticoagulant effect by assessing prothrombin time, reflecting vitamin K-dependent clotting factor inhibition. In atrial fibrillation, therapeutic INR (2.0–3.0) prevents thromboembolism. Monitoring INR ensures effective anticoagulation, making it the critical lab value for warfarin therapy management.
Choice C reason: Hemoglobin level detects bleeding, a warfarin side effect, but does not assess its therapeutic effect. INR directly evaluates anticoagulation, ensuring stroke prevention in atrial fibrillation. Hemoglobin is secondary, monitored for complications, not efficacy, making INR the priority lab value.
Choice D reason: Serum potassium is unrelated to warfarin’s anticoagulant action. Electrolyte imbalances may affect cardiac rhythm in atrial fibrillation, but INR measures warfarin’s effect on clotting factors, ensuring therapeutic anticoagulation, making it the essential value to monitor for medication efficacy.
