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.

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: A

Rationale: The priority action for the healthcare professional is to obtain the client's baseline vital signs and oxygen saturation. This will provide essential information on the client's current physiological status and help guide further assessment and intervention. Assessing the vital signs and oxygen saturation can help identify any immediate concerns like hypoxia or sepsis, which require prompt attention. While obtaining a complete history and considering a pneumococcal vaccine may be important in the overall care of the client, assessing the vital signs and oxygen saturation takes precedence to address the client's immediate physiological needs.

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.

Correct Answer: D

Rationale: Sinusitis is an inflammation of the sinus cavities, which can cause tenderness and pain around the eyes (orbital areas). Palpation of the orbital areas can help identify tenderness and swelling associated with sinusitis. Auscultation of the trachea and percussion of the frontal sinuses are not relevant assessment techniques for sinusitis. Inspection of the nasal mucosa may reveal signs of inflammation, but palpation of the orbital areas is a more direct method to assess for tenderness and swelling in this specific condition.
