A nurse is caring for a school-age child with respiratory failure due to pneumonia. Which position should the nurse encourage to allow for maximal lung expansion?

Prone

Supine

Side-lying

Upright

Answer and Explanation

The Correct Answer is D

Choice A rationale
The prone position, which involves lying flat on the stomach, is not typically recommended for a child with respiratory failure due to pneumonia. While prone positioning can be beneficial in

certain cases of severe acute respiratory distress syndrome, it does not generally allow for maximal lung expansion.
Choice B rationale
The supine position, which involves lying flat on the back, is not typically recommended for a child with respiratory failure due to pneumonia. This position can make it more difficult for the lungs to expand fully, potentially worsening respiratory distress.
Choice C rationale
The side-lying position is not typically recommended for a child with respiratory failure due to pneumonia. While this position can be comfortable for resting, it does not generally allow for maximal lung expansion.
Choice D rationale
The upright position is typically recommended for a child with respiratory failure due to pneumonia. Sitting upright can help to maximize lung expansion and improve oxygenation.

Correct Answer is A

Explanation

The correct answer is Choice A. The client is receiving an oxygen concentration of 28%. Nasal cannulas can deliver oxygen at a flow rate ranging from 1 to 6 liters per minute (L/min), with

each additional liter increasing the fraction of inspired oxygen (FiO2) by 4%. Therefore, at 2 L/min, the client is receiving an oxygen concentration of 28%78.

A. Turn the torso at the waist when reaching for objects. B. Use ice packs intermittently for 48 hours. C. Use 10 lb arm weights to start strengthening the back muscles. D. Stay in bed except for toileting during the first 24 hours.

Correct Answer is B

Explanation

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.
