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

Answer and Explanation

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

The correct answer is choice C: Instruct the UAP to lower the bed for safety.

Choice C rationale: When bathing a bedfast client, the bed should be in a flat or low position to reduce the risk of the client sliding down, falling, or experiencing discomfort or injury. By instructing the UAP to lower the bed, the PN ensures client safety during the bathing process.

Choice A rationale: Assuming care of the client immediately might be unnecessary. The PN should first address the safety concern and then determine if additional intervention is needed.

Choice B rationale: While supervising the UAP may be appropriate in certain situations, the priority in this case is to address the immediate safety concern by instructing the UAP to lower the bed. The PN can then decide if supervision or assistance is required.

Choice D rationale: Determining if the UAP would like assistance is considerate, but it is not the priority in this situation. Ensuring client safety by lowering the bed should be addressed first. The PN can then assess whether the UAP needs any help or guidance.

A. Ketonuria. B. Peripheral edema. C. Hypokalemia. D. Elevated blood pressure.

Correct Answer is C

Explanation

Choice A rationale:

Ketonuria is not a common complication of diabetes insipidus. Ketonuria is associated with diabetes mellitus, a different condition that results in the accumulation of ketones in the urine due to insufficient insulin.

Choice B rationale:

Peripheral edema is also an unlikely complication of diabetes insipidus. Diabetes insipidus is characterized by excessive thirst and urination, not fluid retention or peripheral edema.
