Correct Answer: B

Rationale: When a chest tube is accidentally removed, the priority action for the nurse is to immediately seal the insertion site with a gloved hand, a sterile occlusive dressing, or petroleum gauze to prevent air from entering the pleural space and causing a pneumothorax. Applying sterile gauze to the insertion site is not the correct initial action. The first step is to prevent respiratory compromise by ensuring the site is sealed. Therefore, the nurse should not apply sterile gauze to the insertion site first.

Correct Answer: B

Rationale: During a thoracentesis procedure, the focus is on draining fluid or air from the pleural space. An incentive spirometer, which helps improve lung function, is not a necessary supply for this specific procedure. Oxygen equipment, pulse oximeter for monitoring oxygen saturation levels, and sterile dressing for wound care may be needed during or after the procedure.

Correct Answer: D

Rationale: Following chest tube placement, an indwelling urinary catheter is not typically needed or relevant to the care provided. Chest tube placement is primarily concerned with managing pleural effusion or pneumothorax, and urinary catheterization is not directly related to this procedure. Oxygen, sterile water, and enclosed hemostat clamps are commonly used items in the care of a client with a chest tube in place, to ensure proper oxygenation, maintain drainage system integrity, and manage any bleeding that may occur. Therefore, the indwelling urinary catheter should not be available in the client's room following chest tube placement.

Correct Answer: B

Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.

Correct Answer: C

Rationale: Individuals with global aphasia have difficulty understanding and expressing language. Speaking loudly may not improve comprehension and can be perceived as aggressive. Therefore, it is important not to speak loudly to a client with global aphasia. Speaking at a slower rate, using visual aids like flash cards, and breaking down instructions into simple steps can facilitate communication and understanding for the client.
