The nurse notices redness under the chin of a client who is receiving oxygen at 2 L/minute via a nasal cannula. What action should the nurse take?

Choice A rationale
Osteoarthritis is a type of arthritis that occurs when the cartilage that cushions the ends of your bones in your joints gradually deteriorates. Osteoarthritis symptoms often develop slowly and worsen over time. They can include: Pain in the joint during or after use, or after periods of inactivity, Tenderness in the joint when you apply light pressure to or near it, Stiffness in the joint, that may be most noticeable when you wake up in the morning or after a period of inactivity, Loss of flexibility in the joint, Grating sensation or sound when you use the joint. But in this case, the client’s symptoms do not align with those of osteoarthritis.

Choice B rationale
Rheumatoid Arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. Signs and symptoms of rheumatoid arthritis may include: Tender, warm, swollen joints, Joint stiffness that is usually worse in the mornings and after inactivity, Fatigue, fever and loss of appetite. The client’s symptoms align with those of Rheumatoid Arthritis.

Choice C rationale
Carpal Tunnel Syndrome is a condition that causes numbness, tingling and other symptoms in the hand and arm. Carpal tunnel syndrome is caused by a compressed nerve in the carpal tunnel, a narrow passageway on the palm side of your wrist. The anatomy of your wrist, health problems and possibly repetitive hand motions can contribute to carpal tunnel syndrome. But in this case, the client’s symptoms do not align with those of Carpal Tunnel Syndrome.

Choice D rationale
Gout is a common and complex form of arthritis that can affect anyone. It’s characterized by sudden, severe attacks of pain, swelling, redness and tenderness in the joints, often the joint at the base of the big toe. An attack of gout can occur suddenly, often waking you up in the middle of the night with the sensation that your big toe is on fire. The affected joint is hot, swollen and so tender that even the weight of the sheet on it may seem intolerable. But in this case, the client’s symptoms do not align with those of Gout.

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.
