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: 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: In a client with left homonymous hemianopsia, there is a loss of vision on the right side of both eyes. Placing the bedside table on the right side of the bed ensures that essential items are within the client's field of vision, minimizing the risk of injury or accidents. Teaching the client to scan to the right and orienting them using the clock method may be helpful strategies, but placing the bedside table on the right side of the bed is a more direct and immediate intervention to enhance the client's safety and independence.

Correct Answer: D

Rationale: In a right-hemispheric stroke, the expected findings include left-sided hemiplegia (Choice B), loss of depth perception (Choice C), and impulse control difficulty (Choice A). Aphasia (Choice D) is typically associated with left-hemispheric strokes. Therefore, aphasia is not an expected finding in a client who has experienced a right-hemispheric stroke.

Correct Answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.
