A 10-year-old child with pneumonia is receiving oxygen at 5 L/minute via a nasal cannula.
When planning care for this child, what principle of oxygen administration should the nurse keep in mind?

Avoid administering oxygen at high levels for extended periods.

Increase the oxygen rate during sleep to compensate for a slower respiratory rate.

Taking a sedative at bedtime slows the respiratory rate, which decreases oxygen needs.

Oxygen is less toxic when it is humidified with a hydration source.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Oxygen therapy is a crucial part of the management for patients with severe pneumonia. However, prolonged administration of high concentrations of oxygen can potentially lead to oxygen toxicity, resulting in damage to the cells of the lungs. This is due to the production of

reactive oxygen species which can damage cell structures. Therefore, it is important to avoid administering oxygen at high levels for extended periods.
Choice B rationale
While it might seem logical to increase the oxygen rate during sleep due to a slower respiratory rate, this is not typically recommended. The body’s oxygen requirements do not significantly change during sleep and increasing the oxygen rate could potentially lead to hyperoxia.
Choice C rationale
Sedatives can indeed slow the respiratory rate, but this does not decrease oxygen needs. In fact, it could potentially lead to respiratory depression and hypoxia, especially in a patient with a respiratory illness like pneumonia.
Choice D rationale
Humidification of oxygen can improve patient comfort, especially with high flow rates, by preventing dryness in the nasal passages. However, it does not make oxygen less toxic.

Correct Answer is ["A","C","D","E"]

Explanation

Choice A rationale
A sudden change in behavior, especially confusion and agitation, in an elderly patient could be a sign of a urinary tract infection (UTI). Pain during urination is a common symptom of UTIs.
Therefore, it is crucial to inquire if the patient is experiencing any pain during urination.
Choice B rationale

While a high-protein diet can be beneficial for some patients, there is no direct link between increased protein intake and the alleviation of confusion or agitation in elderly patients.
Therefore, this option is not a necessary immediate action for the nurse to take.
Choice C rationale
Reviewing the patient’s current food and medication allergies is important. Certain medications or foods might cause adverse reactions, including confusion and agitation. Therefore, it is crucial to review the patient’s allergies to rule out any potential allergens as the cause of the sudden change in behavior.
Choice D rationale
A recent fall could potentially lead to a head injury, which might cause confusion and agitation. Therefore, it is important to determine if the patient has recently experienced a fall.
Choice E rationale
Providing instructions on how to take the patient’s temperature is important. Fever could be a sign of an infection or other medical condition that might cause confusion and agitation.
Therefore, knowing how to accurately measure the patient’s temperature can help monitor the patient’s condition.

A. Addiction B. Compulsion C. Obsession D. Phobia

Correct Answer is B

Explanation

Choice A rationale
Addiction refers to a chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences. The intricate handwashing ritual that lasts two hours or more described by the client does not indicate substance use or dependency, which are common characteristics of addiction.
Choice B rationale

Compulsion refers to repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rules that must be applied rigidly. The client’s intricate handwashing ritual that lasts two hours or more and their concern about maintaining cleanliness align with the definition of a compulsion.
Choice C rationale
Obsession refers to recurrent and persistent thoughts, impulses, or images that are experienced, at some time during the disturbance, as intrusive and unwanted. While the client’s concern about maintaining cleanliness could potentially be seen as an obsession, the act of handwashing is a behavior, which aligns more with the definition of a compulsion.
Choice D rationale
Phobia refers to an extreme or irrational fear of or aversion to something. The client’s behavior does not indicate an extreme or irrational fear but rather a compulsion to maintain cleanliness through an intricate handwashing ritual.
