A 10-year-old child with pneumonia is receiving oxygen at 5 L/minute via a nasal cannula.
When planning care for this child, what principle of oxygen administration should the nurse keep in mind?
Avoid administering oxygen at high levels for extended periods.
Increase the oxygen rate during sleep to compensate for a slower respiratory rate.
Taking a sedative at bedtime slows the respiratory rate, which decreases oxygen needs.
Oxygen is less toxic when it is humidified with a hydration source.
The Correct Answer is A
Choice A rationale
Oxygen therapy is a crucial part of the management for patients with severe pneumonia. However, prolonged administration of high concentrations of oxygen can potentially lead to oxygen toxicity, resulting in damage to the cells of the lungs. This is due to the production of
reactive oxygen species which can damage cell structures. Therefore, it is important to avoid administering oxygen at high levels for extended periods.
Choice B rationale
While it might seem logical to increase the oxygen rate during sleep due to a slower respiratory rate, this is not typically recommended. The body’s oxygen requirements do not significantly change during sleep and increasing the oxygen rate could potentially lead to hyperoxia.
Choice C rationale
Sedatives can indeed slow the respiratory rate, but this does not decrease oxygen needs. In fact, it could potentially lead to respiratory depression and hypoxia, especially in a patient with a respiratory illness like pneumonia.
Choice D rationale
Humidification of oxygen can improve patient comfort, especially with high flow rates, by preventing dryness in the nasal passages. However, it does not make oxygen less toxic.

Correct Answer is C
Explanation
Choice A rationale
While the sensitivity of genetic markers can influence the choice of treatment, it is not the primary pathophysiological process involved in BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify genetic mutations that increase the risk of developing certain types of cancer.
Choice B rationale
BRCA1 and BRCA2 do play a role in protecting mature, functioning breast and ovarian cells. However, this is not the primary reason for conducting BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify mutations that increase cancer risk.
Choice C rationale
This is the correct answer. Mutations in BRCA1 or BRCA2 can significantly increase a person’s risk for developing breast and ovarian cancer. Therefore, identifying these mutations through genetic testing can help determine a person’s cancer risk.
Choice D rationale
While inherited mutations in BRCA1 and BRCA2 can influence the prognosis of breast cancer, the primary purpose of BRCA1 and BRCA2 genetic testing is to identify mutations that increase cancer risk, not to determine prognosis.
Correct Answer is ["A","D","E"]
Explanation
Choice A rationale
Teaching the client how to use guided imagery can be a helpful intervention for coping with feelings related to death and dying. Guided imagery can help the client to relax, reduce stress and anxiety, and find comfort.
Choice B rationale
Instructing the client and family to reconsider end of life choices is not typically an appropriate intervention. The nurse should respect the client’s end of life choices and provide support, rather than suggesting they reconsider.
Choice C rationale
Recording the client’s desire to live is not typically an intervention used in hospice care. The focus in hospice care is on providing comfort and quality of life, rather than on prolonging life.
Choice D rationale
Encouraging the family to bring the client old photographs can be a helpful intervention. Looking at old photographs can stimulate memories and conversations, providing comfort and connection.
Choice E rationale
Encouraging the family to visit frequently can be a beneficial intervention. Frequent visits can provide the client with emotional support and companionship, which can be comforting when coping with feelings related to death and dying.
