A nurse is caring for a client who is receiving oxygen at 2 L/min via a nasal cannula. The nurse recognizes the client is receiving which of the following inspired oxygen concentration?
36%
70%
50%
28%
The Correct Answer is D
D. 28%:
When a client receives oxygen via a nasal cannula at a flow rate of 2 L/min, the approximate inspired oxygen concentration is around 24-28%. This is because each liter of oxygen delivered through a nasal cannula adds approximately 4% to the baseline room air concentration of 21%. Therefore, at 2 L/min, the client would be receiving approximately 24-28% inspired oxygen concentration.
A. 36%, B. 70%, C. 50%:
These percentages are not consistent with the oxygen concentration delivered via a nasal cannula at 2 L/min. Higher flow rates or alternative oxygen delivery systems, such as masks or high-flow nasal cannula, would be needed to achieve these concentrations.

Correct Answer is D
Explanation
A) Administer and teach about medications to suppress stage III sleep:
Suppressing stage III sleep is not a primary intervention for sleepwalking and could potentially disrupt the client’s overall sleep quality.
B) Encourage the child to verbalize feelings regarding sleep pattern:
While understanding feelings about sleep patterns may be helpful, it is not the immediate priority in managing sleepwalking.
C) Provide a quiet environment for nighttime sleep:
A quiet environment is generally beneficial for good sleep hygiene but does not directly address the safety concerns associated with sleepwalking.
D) Maintain patient safety during episodes of somnambulism:
Ensuring the client’s safety is the primary focus. Sleepwalking can lead to accidents or injuries; therefore, implementing safety measures to prevent harm during episodes of somnambulism is crucial. This may include securing the environment, using safety gates, and ensuring the client’s immediate surroundings are safe.
Correct Answer is A
Explanation
A. Cancer pain: Cancer pain can result from tumor growth, tissue invasion, or nerve compression caused by cancer. It can be acute or chronic and may vary in intensity. However, in this scenario, the client's pain is specifically associated with dermatitis resulting from radiation therapy, rather than directly from the cancer itself.
B. Acute pain: Acute pain is typically sudden in onset and is often associated with tissue injury or damage. In this case, the painful dermatitis resulting from radiation therapy would be considered acute pain because it is directly related to the recent tissue damage caused by the radiation. Acute pain is usually short-term and resolves as the underlying cause heals or is treated.
C. Chronic pain: Chronic pain persists beyond the expected time for tissue healing and is often associated with conditions such as arthritis or neuropathy. While cancer pain can sometimes become chronic if it persists over time, the pain described in this scenario is more likely to be acute given its association with recent radiation therapy.
D. Neuropathic pain: Neuropathic pain results from damage or dysfunction of the nervous system and can present as shooting or burning sensations. While neuropathic pain can occur in cancer patients, the pain described in this scenario is more likely to be acute and related to tissue damage from radiation therapy rather than neuropathy.
