A client is receiving oxygen at 2 L/min via a nasal cannula. What oxygen concentration is the client receiving?

Choice A rationale
The deltoid muscle is not typically used for injections in newborns. It is not as developed as the vastus lateralis and does not have as much muscle mass.

Choice B rationale
The ventrogluteal muscle is generally not used for injections in newborns. It is not as accessible or as well developed as the vastus lateralis.
Choice C rationale
The dorsogluteal muscle is not recommended for injections in newborns due to the risk of damaging the sciatic nerve.
Choice D rationale
The vastus lateralis muscle is the preferred site for intramuscular injections in newborns. It is the most developed muscle in this age group and is free of major nerves and blood vessels.

Choice A rationale
Turning the torso at the waist when reaching for objects can actually increase the risk of back injury. It’s important to keep the back straight and bend at the knees when lifting or reaching for objects.
Choice B rationale

Using ice packs intermittently for 48 hours is a common recommendation for acute lower back pain. Ice can help reduce inflammation and numb the area, providing relief. It’s important to use the ice packs intermittently, not continuously, to avoid frostbite.
Choice C rationale
Using 10 lb arm weights to start strengthening the back muscles is not recommended for someone with acute lower back pain. Heavy lifting can exacerbate the pain and potentially cause further injury. It’s better to start with gentle, low-impact exercises and gradually increase intensity as the back heals.
Choice D rationale
Staying in bed except for toileting during the first 24 hours is not typically recommended for acute lower back pain. While rest is important, prolonged bed rest can actually lead to muscle stiffness and increased pain. It’s generally recommended to stay as active as possible without exacerbating the pain.
