Which nursing assessment indicates a positive reading of a tuberculin (TB) skin test?

A. "You should inhale through your nose and exhale through your mouth during purse-lipped breathing."

Pursed-lip breathing is a breathing technique commonly used by individuals with COPD to help improve breathing efficiency and manage dyspnea (shortness of breath). During purse-lip breathing, the individual inhales slowly through the nose and exhales slowly and gently through pursed lips, creating a slight resistance to the airflow. This technique helps to keep the airways open longer during exhalation, reduces air trapping, and improves oxygenation.

B. "Your inspiration should be longer than expiration during purse-lipped breathing."

Pursed-lip breathing typically involves making both the inspiration and expiration longer than usual. The focus is on slowing down the breathing rate and extending the exhalation phase to promote better gas exchange and reduce respiratory effort.

C. "You should cough forcefully during exhalation when you are purse-lipped breathing."

Pursed-lip breathing is a gentle breathing technique used to promote relaxation and control of breathing. Forceful coughing during exhalation is not part of purse-lip breathing and may not be appropriate, especially for individuals with COPD who are prone to airway irritation and bronchospasm.

D. "You should be flat on your back when you perform purse-lipped breathing."

The position for performing purse-lip breathing is not specific to lying flat on the back. Individuals can perform purse-lip breathing in various positions that are comfortable and allow for effective breathing, such as sitting upright or leaning slightly forward. The key is to find a position that facilitates relaxation and optimal lung expansion.

A. Prepare the client for endotracheal suctioning.

Endotracheal suctioning is a procedure used to clear secretions from the airway, which may be necessary in cases of respiratory distress. However, it is not the first action to take in this scenario. Before proceeding with suctioning, the nurse should first assess the client's respiratory status and implement interventions to improve ventilation and oxygenation.

B. Elevate the head of the bed.

This is the correct action to take first. Elevating the head of the bed helps improve the client's respiratory mechanics by allowing better lung expansion and reducing the work of breathing. It also helps alleviate symptoms of respiratory distress. This intervention should be implemented immediately to optimize the client's breathing.

C. Request a chest x-ray.

While a chest x-ray may provide valuable information about the client's respiratory status, it is not the first action to take in this acute situation. Chest x-rays require time to be performed and interpreted, which may delay necessary interventions to address the client's immediate respiratory distress.

D. Obtain a sputum culture.

Obtaining a sputum culture may be indicated to identify the underlying cause of respiratory distress, such as infection. However, it is not the first action to take when the client is experiencing acute respiratory distress. The priority is to implement interventions to improve ventilation and oxygenation to stabilize the client's condition.
