A pressure-volume loop develops a pronounced “beak” at the upper portion of inspiration. Which statements correctly describe this finding? I. The pressure-volume loop can be used to recognize alveolar overdistentionII. Upper-loop beaking is consistent with excessive alveolar inflationIII. Persistent overdistention increases the risk of VILI, barotrauma, and pneumothoraxIV. Correction may include reducing VT during volume control or reducing inspiratory pressure during pressure control

Serial pressure-volume loops demonstrate that a patient now requires more pressure to achieve the same tidal volume than earlier. How should this change appear on the loop?

A 68-year-old patient with severe COPD is receiving volume-controlled ventilation and develops progressive dynamic hyperinflation. The expiratory flow waveform fails to return to baseline before the next breath begins. Which ventilator adjustment would be least appropriate for correcting this problem?

Four capstone teams describe the AI agents in their systems. Each description lists what the agent reads, what it can access, and where it can send output. ReleaseBot, Team 1. Reads open issues and comments on the team’s public GitHub repo, where any GitHub user can post. Holds a token scoped to that one public repo only. Can open pull requests and post comments on the same repo. VendorDigest, Team 2. Reads every email that arrives at the purchasing inbox, where any outside sender can write. Can search the company’s contract database, including pricing negotiated with other vendors. Posts a daily summary to a Slack Connect channel that is shared with the company’s external vendors. PolicyHelper, Team 3. Reads the HR handbook, which only the HR team can edit after a review step. Can look up any employee’s personnel record. Can send email to any address, inside or outside the company. DocTranslate, Team 4. Reads text that any visitor pastes into a public web form. Has no access to any database, file store or user account. Returns the translation only to the visitor’s own browser session. Which agent combines all three legs of the lethal trifecta: access to private data, exposure to untrusted content, and the ability to communicate externally?

An executive’s AI assistant prepares a briefing every morning. It works from these sources: The executive’s calendar. Invitations from any sender, inside or outside the company, are added automatically. The assistant reads each event’s title, attendee list, and description. Documents linked from meetings. Many sit in shared folders where outside participants, such as vendors, have edit rights. Web pages about the companies on the agenda. The assistant finds and fetches them on its own. A chat window, where the executive types requests such as “brief me on today’s meetings”. A system prompt, written by the developer and changeable only by the company’s IT team. In an indirect prompt injection, the attacker places instructions in content the agent will read, without ever talking to the agent. Which of the following are channels for indirect prompt injection into this assistant? Select all that apply.
