A nurse is caring for an asthmatic client who requires a low concentration of oxygen. Which delivery device should the nurse use in order to administer oxygen to the client?
face tent
nasal cannula
nonrebreather mask
simple mask
The Correct Answer is B
A. A face tent delivers oxygen but is typically used for clients who cannot tolerate masks and usually provides variable oxygen concentrations.
B. A nasal cannula is appropriate for delivering low concentrations of oxygen (typically 24% to 44%) and allows the client to eat, talk, and move more easily. It is commonly used for clients who need low-flow oxygen therapy, such as those with asthma.
C. A nonrebreather mask delivers high concentrations of oxygen (up to 100%) and is not suitable when only low oxygen concentrations are needed.
D. A simple mask delivers moderate oxygen concentrations (35% to 50%) and is generally used when higher oxygen levels are required than with a nasal cannula.

Correct Answer is C
Explanation
A. Offering iced tea before bed is not appropriate because tea contains caffeine, which can further disrupt sleep.
B. Sleeping without socks has no relevance to sleep disruption related to nocturia (frequent urination at night).
C. Having the client take a diuretic (furosemide) in the morning is the most appropriate intervention. Diuretics increase urine output, and taking them later in the day can lead to nocturia, which disrupts sleep and may contribute to confusion or disorientation in older adults.
D. Encouraging frequent naps during the day can interfere with the client’s nighttime sleep pattern, potentially worsening insomnia or nighttime disorientation.
