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 B
Explanation
Choice A rationale:
Drinking electrolyte fluid replacements may be necessary if the client is dehydrated due to diabetic ketoacidosis (DKA). However, addressing the increased thirst, which is a sign of DKA, should involve insulin administration to correct the underlying problem of high blood sugar.
Choice B rationale:
Giving a dose of regular insulin as prescribed is the most appropriate action to address increased thirst in a client with type 1 diabetes and early signs of DKA. Elevated blood sugar levels are the cause of the increased thirst, and insulin helps lower blood sugar levels.
Choice C rationale:
Resuming normal physical activity may not be advisable when a client is experiencing early signs of DKA. Strenuous physical activity can exacerbate hyperglycemia, and the primary focus should be on insulin administration and rehydration.
Choice D rationale:
Measuring urine output over the next 24 hours is important for monitoring hydration status in a client with DKA. However, the immediate priority is to address the increased thirst and hyperglycemia with insulin therapy.
Correct Answer is B
Explanation
Choice A rationale:
“I should take this medication with food to prevent stomach upset.” Rationale: This statement is not accurate for fluconazole. While some medications should be taken with food to reduce stomach upset, fluconazole is typically taken on an empty stomach. Taking it with food may reduce its absorption.
Choice B rationale:
“I should avoid drinking alcohol while taking this medication.” Rationale: This is the correct response. Fluconazole can interact with alcohol and may lead to increased side effects or reduced effectiveness of the medication. Therefore, it is essential to avoid alcohol while taking fluconazole.
Choice C rationale:
“I should use a barrier method of contraception while taking this medication.” Rationale: While it is generally a good practice to use barrier contraception during treatment for a fungal infection to prevent potential spread to a partner, this statement does not specifically address fluconazole's requirements or interactions.
Choice D rationale:
“I should stop taking this medication if I develop a rash.” Rationale: This statement is not entirely accurate. While it is important to monitor for skin rashes as they can be a sign of an allergic reaction, the decision to stop taking fluconazole should be made in consultation with a healthcare provider. It is not an automatic response to developing a rash.
