A 10-year-old child with pneumonia is receiving oxygen at 5 L/minute via a nasal cannula.
When planning care for this child, what principle of oxygen administration should the nurse keep in mind?

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.

Choice A rationale
Administering the medication at 1000, 1600, 2200, and 0400 would not be the best schedule because it does not evenly distribute the doses throughout the day. This could lead to periods of subtherapeutic medication levels and periods of potential toxicity.
Choice B rationale
Administering the medication with meals and a bedtime snack is not the best schedule for this medication. While some medications need to be administered with food, there is no indication

that this medication needs to be. Furthermore, this schedule could lead to uneven distribution of the medication throughout the day.
Choice C rationale
Giving the medication in equally divided doses during waking hours is not the best schedule because it does not take into account the half-life of the medication or the patient’s sleep schedule. This could lead to subtherapeutic levels of the medication during the night.
Choice D rationale
Administering the medication at 0800, 1200, 1600, and 2000 is the best schedule for this medication. It evenly distributes the doses throughout the day, which can help maintain a therapeutic level of the medication and reduce the risk of toxicity.
