Which lab value is critical to monitor in patients receiving warfarin therapy?

Correct Answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.

Correct Answer: A

Rationale: Administering diuretics is the appropriate management for fluid overload in a patient with heart failure. Diuretics help to reduce fluid retention by increasing urine output, thereby alleviating the fluid overload. Choices B, C, and D are incorrect. Increasing fluid intake would worsen the condition by adding more fluid to an already overloaded system. Providing oral fluids is not specific enough to address the excess fluid in the body, and chest physiotherapy is not indicated for managing fluid overload in heart failure patients.

Correct Answer: A

Rationale: The priority nursing action for a patient with respiratory distress is to administer oxygen. Oxygen therapy is crucial in improving oxygenation levels and relieving respiratory distress, making it the top priority intervention. Repositioning the patient, administering bronchodilators, or providing chest physiotherapy may be necessary interventions depending on the underlying cause, but ensuring adequate oxygen supply should take precedence in addressing respiratory distress.

Correct Answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is crucial in ensuring that the patient receives an adequate supply of oxygen to meet the body's demands. Administering bronchodilators (Choice B) may be beneficial in specific respiratory conditions like asthma or COPD but may not be the primary intervention in all cases of respiratory distress. Administering IV fluids (Choice C) may be necessary in cases of dehydration or shock but would not directly address respiratory distress. Providing chest physiotherapy (Choice D) can help mobilize secretions in conditions like cystic fibrosis but is not the first-line intervention for respiratory distress.
