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 ["A","C","E"]

Explanation

C. Face the client when speaking.

E. Provide the daughter with written instructions.

Choice A rationale:

Including the family in the discharge teaching is essential, especially when dealing with a client who has communication barriers such as hearing loss and illiteracy. Involving the daughter in the teaching process ensures that she is aware of the client's care needs and can provide support at home.

Choice B rationale:

Encouraging the client to attend reading classes is not a practical intervention for an older adult with hearing loss. Reading classes may not address the immediate communication needs of the client, and the client's primary caregiver, in this case, is the daughter who will provide daily care and support.

Choice C rationale:

Facing the client when speaking is a crucial intervention when dealing with someone who has hearing loss. By facing the client, the nurse ensures that the client can see their lips and facial expressions, which can aid in lip-reading and understanding the communication better.

Choice D rationale:

Speaking loudly when teaching is not always the best approach for clients with hearing loss. While it may seem intuitive to speak loudly, it can distort speech and make it more challenging for the client to understand. Clear and slow speech, along with visual cues, is often more effective.

Choice E rationale:

Providing the daughter with written instructions is essential, especially when the client has limited reading skills. Written instructions can serve as a reference guide for the daughter, helping her provide care and support to her father accurately.

A. Serum sodium level. B. Hematocrit. C. Neutrophil count. D. Platelet count.

Correct Answer is C

Explanation

Choice A rationale:

Serum sodium level. Rationale: While electrolyte imbalances can be significant, in the context of purulent drainage at a postoperative site, monitoring serum sodium levels is not the top priority. Other laboratory values are more relevant in this situation.

Choice B rationale:

Hematocrit. Rationale: Hematocrit measures the proportion of red blood cells in the blood and is not directly related to wound drainage or infection. It is not the most relevant parameter to assess in this situation.

Choice C rationale:

Neutrophil count. Rationale: Neutrophils are a type of white blood cell that plays a key role in the body's immune response, particularly against bacterial infections. Elevated neutrophil counts can indicate an ongoing infection, so monitoring this value is important when assessing purulent wound drainage.

Choice D rationale:

Platelet count. Rationale: Platelet count measures the number of blood clotting cells in the blood and is not directly related to wound drainage or infection. It is not the most relevant parameter to assess in this situation.
