Correct Answer: B

Rationale: When assessing a client with a chest tube and drainage system, gentle constant bubbling in the suction control chamber is an expected finding. This indicates that the system is functioning properly. Continuous bubbling in the water seal chamber would suggest an air leak, the drainage system should be positioned upright at chest level to promote proper drainage, and exposed sutures without dressing would be an incorrect finding as they should be covered to prevent infection.

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: C

Rationale: Patients who have experienced a left-hemispheric stroke may exhibit symptoms of agnosia, which is the inability to recognize familiar objects or people. This occurs due to damage to the right hemisphere of the brain, which is responsible for visual and spatial perception. Impulse control difficulty, poor judgment, and loss of depth perception are not typically associated with left-hemispheric strokes.

Correct Answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

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.
