What is the rationale for the order of supplemental oxygen 10 L/min via nasal cannula? Select the best answer.
To prevent hypoxia and tissue damage due to pneumonia.
To lower the blood pressure and reduce the workload of the heart.
To increase the oxygen saturation and improve the respiratory function.
To dilate the bronchioles and decrease the inflammation of the lungs.
The Correct Answer is A
Choice A rationale:
Supplemental oxygen is given to the patient to prevent hypoxia and tissue damage due to pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Hypoxia occurs when the body or a region of the body is deprived of adequate oxygen supply at the tissue level. It can cause serious damage to your heart, brain, and other organs. Hence, supplemental oxygen is administered to ensure that the patient’s tissues receive adequate oxygen.
Choice B rationale:
While supplemental oxygen can indirectly help lower blood pressure by improving oxygen supply and reducing strain on the heart, it is not primarily used for this purpose. Enalapril, which the patient is already taking, is an angiotensin-converting enzyme (ACE) inhibitor that is commonly used to lower blood pressure and reduce the workload of the heart.
Choice C rationale:
Supplemental oxygen does increase the oxygen saturation and improve respiratory function. However, this is a more general rationale for providing supplemental oxygen and not specific to this patient’s condition of pneumonia.
Choice D rationale:
Supplemental oxygen does not directly dilate the bronchioles or decrease inflammation in the lungs. Medications such as bronchodilators and corticosteroids are typically used for these purposes. In this case, supplemental oxygen is being used to prevent hypoxia and tissue damage due to pneumonia.

Correct Answer is C
Explanation
Choice A rationale:
The nurse should respect the client's autonomy and right to make decisions about her own care. It is essential to honor the client's refusal of further treatment, and the nurse should communicate this to the family. In this situation, the client has the capacity to make her own decisions, and her wishes should be respected.
Choice B rationale:
Attempting to persuade the client to participate in the clinical trial for one month is not an appropriate approach. It disregards the client's autonomy and her right to refuse treatment. It's essential to respect the client's decision, and trying to convince her against her will is ethically and legally inappropriate.
Choice D rationale:
While it's important to ensure that the client fully understands the implications of her decision, doing so in front of her children may create additional pressure or discomfort for the client. The best approach is to have a private conversation with the client to assess her understanding and provide information or support as needed.
Correct Answer is C
Explanation
When a preoperative client expresses fear and uncertainty about undergoing surgery, the priority action for the practical nurse (PN) is to notify the charge nurse of the client's concerns. This is important because the charge nurse can coordinate appropriate interventions and support for the client, ensuring their emotional well-being and addressing their fears.
Let's evaluate the other options:
a) Encourage the client to continue with the scheduled surgery.
While it is important to provide support and reassurance to the client, simply encouraging them to continue with the scheduled surgery may not adequately address their specific concerns and fears. The charge nurse and the healthcare team should be involved to provide the necessary support and information to help alleviate the client's anxiety.
b) Document that the client has expressed concerns about the surgery.
Documenting the client's concerns is important for accurate record-keeping and continuity of care. However, it should not be the only action taken. Notifying the charge nurse is crucial to ensure appropriate follow-up and support for the client.
d) Remind the client that the consent has already been obtained.
Reminding the client that they have already signed the informed consent may not effectively address their fears and concerns. Reassurance and support should be provided, and involving the charge nurse and healthcare team is essential to address the client's emotional well-being.
In summary, when a preoperative client confides in the practical nurse (PN) about being frightened and unsure about undergoing surgery, the priority action is to notify the charge nurse of the client's concerns. This allows for appropriate interventions, support, and coordination of care to address the client's fears, ensure their emotional well-being, and provide necessary information about the surgical procedure.
