ATI Fundamentals

Correct Answer: B

Rationale: A Venturi mask is the most appropriate choice for delivering a precise amount of oxygen to a client with dyspnea. Unlike other oxygen delivery devices, the Venturi mask allows for accurate oxygen concentration delivery by controlling the amount of air entrained. This feature is crucial in ensuring the client receives the prescribed oxygen concentration, especially in cases where precise oxygen delivery is required.

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: When assessing a client with a history of asthma, the nurse should identify environmental allergies as a risk factor for asthma. Environmental allergens such as pollen, dust mites, mold, and pet dander can trigger asthma symptoms and exacerbate the condition. Gender, alcohol consumption, and other factors may not directly contribute to the development or exacerbation of asthma.

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: 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.
