ATI Fundamentals

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: 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: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

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.
