Oxygen at 5 L/minute per nasal cannula is being administered to a 10-year-old child with pneumonia. When planning care for this child, which principle of oxygen administration should the nurse consider?

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

Avoid administration of oxygen at high levels for extended periods.

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

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

Answer and Explanation

The Correct Answer is B

A.   Oxygen is less toxic when it is humidified with a hydration source. While humidification can prevent drying of the respiratory mucosa, it does not directly relate to the principle of avoiding high levels of oxygen for extended periods.
B.   Avoid administration of oxygen at high levels for extended periods. This is the correct principle. Prolonged exposure to high levels of oxygen can lead to oxygen toxicity, which can cause lung damage. Oxygen therapy should be titrated to maintain adequate oxygenation without exposing the patient to excessive oxygen levels.
C.   Increase oxygen rate during sleep to compensate for slower respiratory rate. This statement is incorrect. Oxygen therapy should be adjusted based on the patient's oxygen saturation levels and respiratory status, not solely on sleep patterns.
D.   Taking a sedative at bedtime slows respiratory rate, which decreases oxygen needs. While sedatives can depress respiratory rate, leading to decreased oxygen needs, this is not a general principle of oxygen administration. Oxygen therapy should be based on the patient's oxygenation needs rather than medications they are taking.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B","dropdown-group-3":"B"}

Explanation

A. anaphylaxis

The correct answer is A. Anaphylaxis is a severe, life-threatening allergic reaction that can occur in response to medication administration. The client's symptoms of dizziness, headache, burning feeling on extremities, and redness on face and extremities, along with the sudden onset of symptoms after starting vancomycin infusion, are indicative of a possible anaphylactic reaction.

B. arrhythmias

The correct answer is B. Arrhythmias refer to abnormal heart rhythms, which can be

triggered by various factors including medication reactions. Given the client's history of symptomatic bradycardia and the sudden onset of symptoms after starting vancomycin infusion, arrhythmias such as bradycardia or other rhythm disturbances are a concern.

C. Cardiac arrest

The correct answer is C. Cardiac arrest is the cessation of normal heart function, which can be precipitated by severe arrhythmias or anaphylaxis. The client's symptoms, along with the drop in blood pressure, indicate a potential risk of progressing to cardiac arrest if not promptly treated.

D. Necrosis

Necrosis, or tissue death, is not typically associated with the symptoms described in the scenario. While vancomycin infusion can potentially cause tissue irritation or damage at the
injection site, the symptoms described suggest a systemic reaction rather than localized tissue necrosis.

E. Renal failure

Renal failure is not directly indicated by the symptoms described in the scenario. While vancomycin can be nephrotoxic in some cases, the symptoms of dizziness, headache, and redness are more suggestive of an allergic or cardiovascular reaction.

F. Peripheral edema

Peripheral edema, or swelling in the extremities, is not indicated by the symptoms described in the scenario. The client's symptoms, such as dizziness, headache, and redness, are more
indicative of a systemic reaction rather than localized swelling.

A. A B. B C. C D. D

Correct Answer is A

Explanation

A. The neck is the correct location for auscultating a carotid bruit. A carotid bruit is an abnormal sound heard over the carotid artery in the neck, typically indicative of turbulent blood flow due to a narrowing or blockage in the artery.

B. Auscultating the femoral region would not yield information about carotid bruits. The femoral region pertains to the upper thigh area and is not anatomically related to the carotid artery.

C. The cubital fossa is the inner elbow region and is not associated with auscultation for carotid bruits. It is typically used for auscultation of blood pressure using the brachial artery.

D. The navel (belly button) is not a relevant location for auscultation for carotid bruits. It is far from the carotid arteries and would not provide any meaningful information about carotid artery sounds.
