Question

a client who has just had a triple - lumen catheter placed in their right subclavian vein reports chest pain and shortness of breath. the clients blood pressure is decreased from baseline and, on auscultation of their chest, the nurse notes unequal breath sounds. a chest x - ray is immediately ordered by the health care provider. what diagnosis should the nurse suspect?
myocardial infarction (mi)
pneumothorax
pulmonary embolism
heart failure

Explanation:

1. Analyze each option:

• Myocardial infarction (MI): Typically presents with chest pain, but unequal breath sounds and the context of a recently placed catheter make this less likely. MI is more related to heart muscle damage from blocked coronary arteries, not directly associated with catheter placement - related chest and breath issues.
• Pneumothorax: A complication of central line (like triple - lumen catheter) placement in the subclavian vein. It can cause chest pain, shortness of breath, decreased blood pressure (due to compromised respiratory function and possible mediastinal shift), and unequal breath sounds (because air in the pleural space collapses the lung on one side).
• Pulmonary embolism: Usually presents with sudden shortness of breath, chest pain, and may have other signs like tachycardia, but it is more associated with deep vein thrombosis and blood clots traveling to the lungs. The immediate complication of subclavian catheter placement is less likely to be a pulmonary embolism compared to pneumothorax.
• Heart failure: Presents with signs like edema, dyspnea on exertion, and has a more chronic or progressive onset in most cases. The acute onset after catheter placement and unequal breath sounds are not typical of heart failure.

1. Based on the client's recent triple - lumen catheter placement in the subclavian vein and the symptoms (chest pain, shortness of breath, decreased BP, unequal breath sounds), pneumothorax is the most likely diagnosis.

Answer:

B. Pneumothorax
