ATI Fundamentals

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: B

Rationale: The correct answer is, 'I take this medication to prevent asthma attacks.' Bronchodilators are commonly used to relieve bronchospasm in conditions such as asthma. This medication helps to dilate the airways, making it easier to breathe and preventing asthma attacks. The other options are incorrect: option A is inaccurate as bronchodilators do not decrease immune responses, option C is incorrect as bronchodilators are typically taken on an empty stomach for better absorption, and option D is false as bronchodilators have a rapid onset to provide quick relief of symptoms.

Correct Answer: D

Rationale: During the removal of a chest tube, instructing the client to perform the Valsalva maneuver is essential. This maneuver involves holding the breath and bearing down, which helps prevent air from entering the pleural space during tube removal, reducing the risk of pneumothorax. Instructing the client to lie on their left side, use the incentive spirometer, or cough at regular intervals is not appropriate during the chest tube removal process.

Correct Answer: D

Rationale: When caring for a client with dysphagia, it is crucial to ensure safe feeding practices. Assigning an assistive personnel to feed the client slowly may not be appropriate as it can increase the risk of aspiration. Thickened liquids, having suction equipment available, and placing food on the unaffected side of the mouth are all appropriate measures to support a client with dysphagia in safe eating and drinking.

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.
