A nurse is caring for a client who is receiving oxygen therapy via a nasal cannula. How should the nurse explain to the client how this method of oxygen delivery performs?
Delivers a low concentration of oxygen.
Delivers a constant rate of oxygen.
Delivers a high concentration of oxygen.
Delivers a constant flow of a specific concentration of oxygen.
The Correct Answer is D
Choice A Reason:
“Delivers a low concentration of oxygen” is incorrect because a nasal cannula can deliver varying concentrations of oxygen depending on the flow rate set by the healthcare provider. The concentration can range from low to moderate, typically between 24% to 44%.
Choice B Reason:
“Delivers a constant rate of oxygen” is partially correct but not entirely accurate. While the flow rate can be constant, the key aspect is the specific concentration of oxygen delivered, which is more relevant to the client’s understanding.
Choice C Reason:
“Delivers a high concentration of oxygen” is incorrect because nasal cannulas are generally used for low to moderate oxygen delivery. High concentrations of oxygen are typically delivered through other devices like non-rebreather masks or high-flow nasal cannulas.
Choice D Reason:
“Delivers a constant flow of a specific concentration of oxygen” is correct. This explanation accurately describes how a nasal cannula works. It provides a continuous flow of oxygen at a specific concentration, which is adjusted based on the client’s needs and the healthcare provider’s prescription.

Correct Answer is A
Explanation
Choice A reason: This statement reflects denial, which is a common initial reaction in the grief process. The client is not accepting the reality of their prognosis and believes the doctor is exaggerating. Denial serves as a defense mechanism to protect the individual from the emotional impact of the diagnosis. It is a way for the client to cope with the overwhelming news by rejecting its truth.

Choice B reason: This statement reflects anger, another stage in the grief process. The client is expressing disbelief and frustration towards the doctor’s competence. Anger often follows denial and is directed towards others as a way to cope with the emotional pain. It is not indicative of denial but rather a progression in the grieving process.
Choice C reason: This statement reflects acceptance of the physical symptoms and the reality of the client’s condition. The client acknowledges their lack of energy and the impact of the illness on their daily life. This is not a sign of denial but rather an acceptance of their current state.
Choice D reason: This statement reflects acceptance and gratitude towards the doctor. The client recognizes the efforts made by the healthcare team and accepts that their time is limited. This is a sign of acceptance, the final stage in the grief process, where the individual comes to terms with their situation.
Correct Answer is A
Explanation
Choice A reason: Guided meditation and other nonpharmacological pain interventions can help reduce the perception of pain, which may allow for lower doses of pain management medications. This is beneficial as it can reduce the risk of side effects and dependency associated with higher doses of pain medications1. Studies have shown that integrating nonpharmacological methods like guided meditation can enhance overall pain management and improve the quality of life for patients2.
Choice B reason: Guided meditation is a complementary therapy and is not intended to replace pain medications entirely. While it can significantly aid in pain management, it is typically used alongside pharmacological treatments to provide a holistic approach to pain relief3. Relying solely on guided meditation without appropriate medical supervision and medication can lead to inadequate pain control.
Choice C reason: Guided meditation is not limited to hospital settings or licensed therapists. Many guided meditation resources are available online, through apps, or in community centers, making it accessible to a broader audience4. Patients can practice guided meditation at home, which provides flexibility and convenience in managing chronic pain.
Choice D reason: Pain medications are often prescribed on a regular schedule to maintain consistent pain control, especially in chronic pain conditions. While nonpharmacological interventions can reduce the need for frequent dosing, they do not eliminate the necessity for scheduled pain medications5. It is essential to follow a healthcare provider’s recommendations for medication administration to ensure effective pain management.
