A nurse is monitoring a client following a thoracentesis. The nurse should identify which of the following manifestations as a complication and contact the provider immediately?

A. “Check your oxygen equipment once each week.”
Checking the oxygen equipment once a week is insufficient. The equipment should be regularly inspected for safety, including tubing, connections, and the condition of the oxygen concentrator or tank.

B. “Do not adjust the oxygen flow rate.”
The nurse should include in the teaching that the client should not adjust the oxygen flow rate without consulting their healthcare provider. Adjusting the oxygen flow rate without proper guidance can lead to inappropriate oxygen delivery, which may be harmful.

C. “Store unused oxygen tanks horizontally.”
Oxygen tanks should be stored in an upright position to prevent damage to the tank valve. Storing them horizontally can increase the risk of leaks or damage.

D. “Keep wool blankets on your bed.”
Wool blankets and other items that generate static electricity should be avoided near oxygen equipment, as they can increase the risk of fire. The client should be advised to use non-static bedding and clothing.

A. Decreased lung sounds
A decrease in lung sounds could indicate a pneumothorax, which is a potential complication of thoracentesis. It requires prompt evaluation.

B. Heart rate 110/min and regular
A heart rate of 110/min is within a normal range, and regular rhythm is generally acceptable post-thoracentesis. It may be related to pain or anxiety but is not an immediate concern.

C. Oxygen saturation of 95%
An oxygen saturation of 95% is within an acceptable range. While maintaining adequate oxygenation is important, this finding does not suggest an immediate complication.

D. Subcutaneous emphysema
Subcutaneous emphysema involves the presence of air in the subcutaneous tissues and can indicate a communication between the pleural space and subcutaneous tissues. This requires immediate attention.

E. Trachea midline
The trachea being midline is a normal finding and does not indicate an immediate problem post-thoracentesis.

F. Puncture site dry
A dry puncture site is expected after a thoracentesis. This finding is normal and indicates appropriate wound care. It is included in the list to ensure recognition of normal post-procedure findings.
