A client smoking in his bathroom has dropped a cigarette butt into a wastepaper basket, which begins to smolder. Which of the following actions is the nurse’s priority?

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.

A. Assessing a client who experiences unilateral calf pain when ambulating.
Unilateral calf pain in a client who is ambulating can be indicative of a potential deep vein thrombosis (DVT), which is a serious condition that requires prompt assessment and intervention. DVTs are a risk after surgery, and early detection is crucial to prevent complications such as a pulmonary embolism. Assessing the client experiencing calf pain is the priority to determine the cause and initiate appropriate interventions.

B. Reassuring the partner of a client who sustained a closed head injury:
While providing support and reassurance to family members is important, it is not as urgent as assessing a client with potential signs of a DVT.

C. Taking a telephone prescription about a client who is to be transferred from PACU:
While obtaining and implementing orders in a timely manner is important, assessing and addressing a potential DVT takes precedence due to the immediate risk to the client's well-being.

D. Reinforcing a client’s dressing for the surgical site of an above-the-knee amputation:
Dressing reinforcement is important for wound care, but it is not as urgently needed as assessing a client with possible signs of a DVT. The assessment of calf pain takes priority.
