The nurse who is assessing a clients chest tube insertion site notices a fine crackling sound and feeling upon palpating the area. What action should the nurse take?

Correct Answer: B

Rationale: Crackling (subcutaneous emphysema) indicates air in subcutaneous tissues possibly from a poor chest tube seal. Collaborating with the physician (B) is necessary to evaluate and address the issue as it may require intervention. Discontinuing suction (A) or removing the tube (C) is unsafe without physician guidance. Reinforcing the dressing (D) does not address the underlying cause making B the appropriate action.

Correct Answer: D

Rationale: Arterial blood gas (ABG D) measures $\mathrm{PaO} 2$ and $\mathrm{PaCO} 2$ directly assessing gas exchange efficiency and hypoxia severity. Blood glucose (A) potassium (B) and sodium (C) do not reflect oxygenation status making D the critical lab value for evaluating respiratory function and hypoxia.

Correct Answer: A

Rationale: A comprehensive respiratory history includes lifestyle (A) for risk factors (e.g. smoking) presence of cough (B) for type and duration sputum production (C) for characteristics and pain (D) for location and impact on breathing. Diet (E not listed) is less relevant making A

Correct Answer: B

Rationale: Lung sounds before and after Oxygen saturation after) Documentation includes sputum characteristics (A) for infection monitoring lung sounds before (C) and after (D) to assess effectiveness and oxygen saturation after (E) for hypoxia evaluation. Sterile solution amount (B) is not typically documented making A C D essential for comprehensive records.
