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 B
Explanation
Stomatitis refers to the inflammation of the mouth and oral mucosa, which can cause pain and difficulty swallowing. In the context of a client receiving chemotherapy, stomatitis is a common side effect that can occur due to the effects of chemotherapy on rapidly dividing cells, including those in the oral cavity. When a client develops stomatitis, it is important for the practical nurse (PN) to obtain information about the client's ability to swallow during a focused assessment. This is because stomatitis can significantly impact a client's ability to eat and drink comfortably, which can lead to dehydration and malnutrition. Assessing the client's ability to swallow helps determine the extent of the issue and guides appropriate interventions and support.
Let's briefly evaluate the other options:
a) Urinary output.
Urinary output is not directly related to stomatitis. Stomatitis primarily affects the oral cavity, and its impact on urinary output is minimal or nonexistent. While monitoring urinary output is important for assessing hydration status, it is not the priority in this situation.
c) Frequency of bowel movements.
The frequency of bowel movements is unrelated to stomatitis. Stomatitis primarily affects the mouth, and its presence does not directly influence bowel movements. Assessing bowel movements may be relevant for other concerns, but it is not specifically related to stomatitis.
d) Blood pressure while standing.
Blood pressure while standing, also known as orthostatic blood pressure, is not directly relevant to stomatitis. Stomatitis primarily affects the oral cavity and does not typically have a direct impact on blood pressure. Assessing blood pressure while standing may be appropriate for other health concerns, such as orthostatic hypotension, but it is not the priority in this situation.
In summary, when a client receiving chemotherapy develops stomatitis, the practical nurse should focus on assessing the client's ability to swallow as it directly relates to the impact of stomatitis on the client's nutrition and hydration.

Explanation
Let’s calculate the infusion rate step by step:
- Convert 1 liter to mL: 1 liter = 1000 mL.
- Calculate total infusion time in minutes: 12 hours = 12 × 60 = 720 minutes.
- Calculate the rate in mL/min: Rate = Total Volume ÷ Total Time = 1000 mL ÷ 720 min = 1.39 mL/min.
- Calculate the drip rate in gtt/min: Drip Rate = Rate (mL/min) × Drip Factor (gtt/mL) = 1.39 mL/min × 15 gtt/mL = 20.85 gtt/min.
If rounding is required, we round to the nearest whole number. So, the nurse should regulate the infusion to 21 gtt/min.
