Correct Answer is D
Explanation
Choice A rationale
Apnea, defined as a temporary cessation of breathing, is not a typical new-onset finding in pulmonary embolism. While severe pulmonary embolism can lead to respiratory compromise, the initial physiological response is usually hyperventilation and tachypnea as the body attempts to compensate for impaired gas exchange and hypoxemia. Apnea suggests a more profound central nervous system or respiratory center depression.
Choice B rationale
A wet cough, characterized by the production of mucus or sputum, is more commonly associated with conditions causing fluid accumulation in the airways, such as pneumonia, bronchitis, or heart failure. In pulmonary embolism, the primary issue is obstruction of pulmonary arteries, leading to V/Q mismatch and hypoxemia, which typically presents with a dry cough or hemoptysis if infarction occurs.
Choice C rationale
Dull chest pain is a less specific symptom and can be associated with various conditions. While chest pain can occur in pulmonary embolism due to pleural irritation or myocardial ischemia from increased right ventricular workload, it is often described as sharp, pleuritic, and sudden in onset. Dull pain might be more indicative of musculoskeletal issues or stable angina.
Choice D rationale
Tachypnea, an abnormally rapid rate of breathing, is a hallmark and early clinical sign of pulmonary embolism. The presence of a pulmonary embolus obstructs blood flow to a portion of the lung, leading to ventilation-perfusion (V/Q) mismatch and hypoxemia. The body compensates by increasing the respiratory rate to improve oxygen uptake and carbon dioxide elimination.
