What is the best intervention for a patient with a suspected pulmonary embolism?

Correct Answer: A

Rationale: Administering oxygen is the best intervention for a patient with a suspected pulmonary embolism because it helps alleviate respiratory distress and improve oxygenation. Oxygen therapy is crucial to ensure adequate oxygen levels in the blood due to the obstruction in the pulmonary circulation caused by the embolism. Administering anticoagulants (choice B) is a treatment for confirmed pulmonary embolism rather than a suspected case. Repositioning the patient (choice C) or administering bronchodilators (choice D) would not directly address the underlying issue of impaired gas exchange and oxygen delivery associated with pulmonary embolism.

Correct Answer: A

Rationale: Administering diuretics is the best method to manage fluid overload in a patient with heart failure. Diuretics help to remove excess fluid from the body by increasing urine output, thus reducing the fluid volume in the bloodstream and tissues. Providing oral fluids (choice B) or increasing fluid intake (choice C) would exacerbate the fluid overload rather than managing it. Chest physiotherapy (choice D) is not indicated for managing fluid overload in heart failure; it is more commonly used for conditions affecting the lungs or airways.

Correct Answer: A

Rationale: The correct initial intervention for a patient with chest pain is to administer aspirin. Aspirin helps reduce the risk of clot formation by inhibiting platelet aggregation, which can be beneficial in case the chest pain is due to a cardiac event. Administering nitroglycerin may follow aspirin administration to help relieve chest pain by dilating blood vessels. Providing pain relief is a general approach and may not address the underlying cause of chest pain. Preparing for surgery would not be the initial intervention for chest pain unless there are specific indications for immediate surgical intervention.

Correct Answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

Correct Answer: A

Rationale: The correct answer is to 'Assess the patient for injuries' when a patient experiences a fall. This is crucial to promptly identify any injuries and provide appropriate care. Calling for help may be necessary, but assessing the patient's condition takes precedence to ensure immediate attention to any injuries. Documenting the fall and notifying the healthcare provider would follow after the initial assessment and necessary actions have been taken.
