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: 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: A

Rationale: The correct answer is, 'I should wash my hands after blowing my nose to prevent spreading the virus.' This statement shows understanding of the importance of hand hygiene in preventing the spread of influenza. Washing hands after activities like blowing the nose can help reduce the risk of transmitting the virus to others. Choices B, C, and D are incorrect as they do not reflect accurate understanding of influenza prevention measures.

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: 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.
