A client with persistent low back pain has received a prescription for an electronic stimulator (TENS) unit. After the nurse applies the electrodes and turns on the power, the client reports feeling a tingling sensation. How should the nurse respond?

A) Incorrect- Dullness bilaterally on percussion is not a normal finding, but it is not an immediate concern after thoracentesis. It may indicate fluid accumulation or consolidation in both lungs, which could be related to other conditions such as pneumonia or heart failure.
B) Incorrect- Serosanguinous drainage from the chest tube is expected after thoracentesis, as long as it is not excessive or continuous. The nurse should monitor the amount and color of the drainage and document it accordingly.
C) Incorrect- Diminished breath sounds in the left lower lobe are also expected after thoracentesis, as the procedure removes fluid and air from the pleural space and reduces lung expansion. The nurse should auscultate the lungs before and after the procedure and compare the findings. The breath sounds should improve gradually as the lung re-expands.
D) Correct- This is a sign of tension pneumothorax, which is a life-threatening complication of thoracentesis. Tension pneumothorax occurs when air accumulates in the pleural space and creates positive pressure that pushes the mediastinum (the heart, great vessels, and trachea) to the opposite side of the chest. This can impair venous return, cardiac output, and respiratory function. The nurse should report this finding to the healthcare provider immediately and prepare to assist with needle decompression or chest tube insertion.

A) Incorrect- This behavior is not safe for maintaining balance. Bending from the waist can increase the risk of falling. Clients should bend at the knees and use proper body mechanics to pick up objects from the floor.
B) Correct- Widening the stance provides a broader base of support, which can help improve balance and stability while working near the sink. This is a safe behavior to maintain balance.
C) Incorrect- Locking the knees while standing can lead to instability and decreased balance. It is recommended to keep the knees slightly flexed to maintain better balance.
D) Correct- Bringing a heavy object close to the body before lifting minimizes strain on the back and helps maintain balance. This is a safe behavior when lifting objects.
E) Incorrect- Leaning forward to pull an object from a high shelf can disrupt the center of balance and increase the risk of falling. It's important to use a step stool or ask for assistance when reaching for items on high shelves.
