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.
None
None
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 ["A","D","E"]
Explanation
Choice A rationale:
Correcting electrolytes that are out of normal range is a crucial goal of therapy for this client. In diabetic ketoacidosis (DKA), the body’s cells are unable to use glucose for energy due to a lack of insulin. This leads to the breakdown of fat for energy, producing ketones as a by-product. Ketones are acidic and can cause the blood’s pH to decrease, leading to metabolic acidosis. This process also leads to an increased production and excretion of electrolytes such as potassium and sodium. Therefore, correcting these electrolyte imbalances is a key goal of therapy.
Choice B rationale:
While promoting oxygenation to tissues is generally important in critical care, it is not a specific goal in the management of DKA. The primary issues in DKA are metabolic in nature, including hyperglycemia, ketosis, and acidosis.
Choice C rationale:
Preventing hyperventilation is not a specific goal in the management of DKA. Hyperventilation in DKA is a compensatory mechanism for metabolic acidosis (Kussmaul breathing). The body tries to expel more carbon dioxide to reduce the acidity of the blood.
Choice D rationale:
Reversing dehydration is another important goal of therapy for this client. In DKA, high blood glucose levels lead to osmotic diuresis, where water is drawn into the urine from the blood, leading to dehydration. This can cause hypotension and reduced tissue perfusion. Therefore, reversing dehydration through fluid replacement is a key part of treatment.
Choice E rationale:
Replacing insulin is a fundamental goal of therapy for this client. Insulin deficiency is the primary cause of DKA. Insulin allows glucose to enter cells where it can be used for energy, preventing the breakdown of fat for energy and the subsequent production of ketones.
Choice F rationale:
Providing respiratory support may be necessary in severe cases of DKA where the patient’s compensatory respiratory efforts are insufficient to maintain adequate gas exchange. However, it is not one of the primary goals of therapy in DKA management.
Correct Answer is ["B","D"]
Explanation
The correct answer is choice b. Apple juice and d. Chicken broth.
Choice A rationale:
Orange juice is a clear liquid and generally acceptable on a clear liquid diet. However, it is not the best choice for someone following Mormon beliefs due to its acidity, which might not be suitable post-surgery.
Choice B rationale:
Apple juice is a clear liquid and suitable for a clear liquid diet. It is also non-caffeinated and non-alcoholic, aligning with Mormon dietary restrictions.
Choice C rationale:
Hot chocolate contains caffeine and is not considered a clear liquid. It is not suitable for a clear liquid diet and does not align with Mormon dietary restrictions.
Choice D rationale:
Chicken broth is a clear liquid and suitable for a clear liquid diet. It is non-caffeinated and non-alcoholic, making it appropriate for someone following Mormon beliefs.
Choice E rationale:
Black coffee contains caffeine, which is prohibited in the Mormon diet. It is also not recommended on a clear liquid diet.
