The primary caregiver of an elderly patient contacts the nurse at the outpatient clinic due to a sudden change in the patient’s behavior.

The caregiver informs the nurse that the patient, who is usually oriented and able to answer Questions, is now confused and agitated.

What actions should the nurse take? (Select all that apply)

Clinical Rationale

Choice B (Correct): To ensure a proper seal and maintain the prescribed $FiO_2$, the mask must be secured over the bridge of the nose first, then pulled down to cover the mouth and chin. A snug fit prevents oxygen from leaking toward the eyes, which can cause irritation, and ensures the client receives the full benefit of the oxygen therapy.

Choice A (Incorrect): Simple face masks used in acute care are generally disposable, single-patient-use items. Cleaning them with soap and water is not standard practice and could introduce contaminants or moisture that compromises the equipment.

Choice C (Incorrect): A client with an oxygen saturation of 89% is hypoxic and requires continuous supplemental oxygen. Taking frequent "breaks" would cause the saturation to drop further, potentially leading to respiratory distress or cardiac strain.

Choice D (Incorrect): For an oxygen mask to be effective, it must cover both the nose and the mouth. Leaving the nose exposed allows the client to inhale room air (21% oxygen), which dilutes the supplemental oxygen and fails to reach the desired therapeutic level.

Choice E (Incorrect): Oxygen is a medication that requires a provider's order. While a nurse may titrate oxygen based on specific standing orders (e.g., "titrate to keep $SpO_2$ > 92%"), a nurse cannot unilaterally "adjust" levels without a protocol or direct order in place.

Choice A rationale
While obtaining an analgesic prescription might help to alleviate the client’s joint pain, it is not the first intervention that should be implemented. The client’s vital signs indicate that they are in a state of shock, which is a medical emergency.

Choice B rationale
Infusing an intravenous fluid bolus is often the first step in treating shock. The client’s low blood pressure and high heart rate suggest that they may be experiencing hypovolemic shock, which can be caused by a severe fluid loss. Administering fluids can help to increase blood volume and improve blood pressure.

Choice C rationale
Administering a PRN oral antipyretic would not address the client’s immediate need. The client’s high temperature is a concern, but the low blood pressure and high heart rate are more immediate concerns.

Choice D rationale

Covering the client with a cooling blanket would address the client’s high temperature, but it would not address the more immediate concerns of low blood pressure and high heart rate.
