A nurse is providing education to a new graduate nurse regarding the correct application and use of a simple face mask for a client with a respiratory rate of 24/min and an oxygen saturation of 89%. Which of the following statements by the new graduate nurse indicates an understanding of the procedure?
I should clean the face mask with soap and water once per shift.
I should place the mask over the bridge of the nose first and then cover the mouth.
The mask should be positioned to cover only the mouth to allow for nasal expiration.
I can adjust the oxygen flow rate independently if the client's saturation does not improve.
I can adjust the oxygen level
Correct Answer : B,C,E
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.

Correct Answer is A
Explanation
Choice A rationale
If a patient suddenly experiences numbness and weakness on the right side of their body, including their arm and leg, and a distinct droop on the right side of the patient’s face, these are warning signs of a stroke. The nurse’s first course of action should be to initiate two large- bore IV catheters and review the inclusion criteria for IV fibrinolytic therapy. This is because rapid administration of fibrinolytic therapy can significantly improve outcomes in patients with acute ischemic stroke.
Choice B rationale
Continuous observation for transient episodes of neurologic dysfunction is important, but the immediate priority is to prepare for potential fibrinolytic therapy.
Choice C rationale
Elevating the head of the bed to 30 degrees and keeping the head and neck in neutral alignment can be beneficial in certain situations, but it is not the immediate priority in this scenario.
Choice D rationale
Administering aspirin can help prevent further clot formation and platelet aggregation in patients with acute coronary syndrome or those at high risk of cardiovascular disease.
However, in the case of a suspected stroke, immediate medical evaluation and potential fibrinolytic therapy are the priorities.
Correct Answer is D
Explanation
Choice A rationale
Mixing the dextrose in a 50 mL piggyback for a total volume of 100 mL is not the appropriate method for administering the medication. This would dilute the dextrose, reducing its concentration and potentially making it less effective.
Choice B rationale
Diluting the dextrose in one liter of 0.9% normal saline solution is not the appropriate method for administering the medication. This would significantly dilute the dextrose, reducing its concentration and potentially making it less effective.
Choice C rationale
Requesting the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution is not the appropriate method for administering the medication. While dextrose is often a component of TPN solutions, in this case, the patient requires a concentrated dose of dextrose to treat insulin shock.
Choice D rationale
This is the correct answer. Administering the undiluted dextrose slowly through the currently infusing IV is the appropriate method for administering the medication. This allows for the rapid administration of a concentrated dose of glucose, which is necessary to quickly raise the patient’s blood glucose level in the case of insulin shock.
