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 B

Explanation

Choice B rationale:

Choice A rationale:

Gathering information regarding how long it will take for the children to arrive is important but does not address the immediate need for information on the dying process.

Choice C rationale:

Offering to discuss the client's health status with each of the adult children is a good approach for involving them in their father's care but does not provide the immediate information the wife is seeking.

Choice D rationale:

Reassuring the spouse that the healthcare provider will notify when to call the children does not offer information about the dying process itself, which is what the wife is interested in understanding.

A. States her feet are constantly cold along with feeling numb B. Consecutive evening serum glucose greater than 260 mg/dL C. A wound on the ankle that starts to drain and becomes painful D. Reports nausea in the morning but still able to eat breakfast

Correct Answer is B

Explanation

The correct answer and explanation is:

b) Consecutive evening serum glucose greater than 260 mg/dL.

This is the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. Consecutive evening serum glucose greater than 260 mg/dL indicates hyperglycemia, which means that the client's blood sugar is too high and not well controlled by the insulin dose.

The PN should report this finding to the healthcare provider and expect a possible adjustment in the insulin regimen.

a) States her feet are constantly cold along with feeling numb.

This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus.

States her feet are constantly cold along with feeling numb may indicate peripheral neuropathy, which is a complication of diabetes that aﬀects the nerves in the feet and legs. It is caused by chronic high blood sugar levels over time, not by a single dose of insulin.

c) A wound on the ankle that starts to drain and becomes painful.

This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. A wound on the ankle that starts to drain and becomes painful may indicate an infection, which is a risk factor for diabetic clients due to impaired wound healing and immune function. It is not directly related to the insulin dose, although it may aﬀect the blood sugar levels and require more insulin.

d) Reports nausea in the morning but still able to eat breakfast.

This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. Reports nausea in the morning but still able to eat breakfast may indicate morning sickness, which is a common symptom of pregnancy. It is not related to the insulin dose, although it may aﬀect the blood sugar levels and require more frequent monitoring and adjustment.
