A Venturi mask is unique from other oxygen delivery methods because it:
allows oxygen to reach lower into the lungs
contains an oxygen reservoir bag
administers the highest percentage of oxygen
has a flow control meter attached
The Correct Answer is D
A. allows oxygen to reach lower into the lungs: While oxygen delivery devices aim to increase alveolar oxygenation, the Venturi mask does not specifically direct oxygen deeper into the lungs. Oxygen distribution depends on tidal volume and patient effort rather than the mask type itself, so this is not the distinguishing feature of a Venturi mask.
B. contains an oxygen reservoir bag: Oxygen reservoir bags are characteristic of non-rebreather and partial rebreather masks, not Venturi masks. These bags store a high concentration of oxygen for inhalation, whereas the Venturi mask relies on precise air-entrainment to deliver a controlled FiO₂.
C. administers the highest percentage of oxygen: Non-rebreather masks deliver the highest concentration of oxygen (up to ~100%), whereas Venturi masks are designed to deliver precise, lower concentrations (e.g., 24–50%) for patients requiring controlled oxygen therapy.
D. has a flow control meter attached: The Venturi mask uses an air-entrainment system with a flow control adapter to deliver a precise and predictable fraction of inspired oxygen (FiO₂). This allows clinicians to carefully titrate oxygen for patients with chronic respiratory conditions, such as COPD, minimizing the risk of hypercapnia from excessive oxygen administration.

Correct Answer is C
Explanation
A. Encourage the client to research the procedure online: While providing additional information can be helpful, asking a client to research a complex surgical procedure online may expose them to inaccurate or misleading information. It also does not address the immediate barrier to comprehension during the consent discussion.
B. Provide the client with a pamphlet of the procedures: Pamphlets can supplement understanding, but they are often written at a reading level that may still be difficult for some clients. They are insufficient on their own to ensure informed consent if the client is struggling to follow the real-time conversation and requires verbal clarification.
C. Ask the surgeon to slow the pace and avoid medical jargon: This action directly addresses the client’s difficulty understanding the procedure. Simplifying language, using lay terms, and slowing the explanation ensures the client can comprehend the information necessary to give informed consent. It reflects advocacy for patient comprehension and supports ethical and legal standards in the consent process.
D. Ask the surgeon to repeat the explanation over again: Simply repeating the explanation at the same pace using the same terminology may not improve understanding. Without adjusting the language or providing clarification, the client may remain confused, and informed consent may still not be achieved.
Correct Answer is B
Explanation
A. "Client found on floor despite repeated reminders to use call light. No injuries noted. Soft wrist restraints applied per provider orders.": Documenting the use of restraints without clear justification or physician orders specific to fall prevention may imply inappropriate use, and this wording also introduces judgment about the patient’s behavior (“despite repeated reminders”), which is not objective or professional documentation.
B. "Client discovered lying on floor in room. Provider called to bedside. No injuries noted. Client returned to bed with bed alarm on, call light in reach.": This entry objectively describes the event, the immediate clinical response, and the interventions implemented to prevent recurrence. It avoids judgmental language and focuses on factual, patient-centered actions, aligning with professional standards for incident documentation in nursing notes.
C. "Client fell out of bed. Provider notified. No apparent injuries. Client reminded to use call light. Side rails up x 4.": While factual, this documentation includes assumptions (“fell out of bed”) and focuses more on restraint or safety devices rather than emphasizing objective observation and immediate care. “No apparent injuries” is slightly less precise than “no injuries noted” in clinical reporting.
D. "Client discovered out of bed on the floor after side rails left down. Client not injured. See incident report.": Including blame or speculative cause (“after side rails left down”) is inappropriate for nursing progress notes, which should remain objective and free from judgment. Referring to an incident report without documenting the nursing assessment and immediate interventions provides incomplete information for continuity of care.
