A nurse is caring for a client who has pneumonia and has been receiving oxygen therapy for several days.
Which of the following findings should the nurse identify as an indication of an adverse effect of oxygen therapy?

Choice A rationale:

Administering insulin is a crucial step in managing diabetic ketoacidosis (DKA), as insulin deficiency is a primary cause of DKA12. However, it is not the first action to take when a patient presents with both DKA and hypoxia. While insulin helps to reduce blood glucose levels and suppress the production of ketones, it does not address the immediate life-threatening condition of hypoxia.

Choice B rationale:

Hypoxia, or low levels of oxygen in the body, is a medical emergency that requires immediate attention. Supplemental oxygen can help increase the oxygen levels in the patient’s blood, thereby alleviating hypoxia. In the context of a patient with DKA and hypoxia, providing supplemental oxygen would be the first action to take to stabilize the patient’s condition before addressing the DKA12.

Choice C rationale:

Checking the patient’s glucose level is an important part of managing DKA, as hyperglycemia is a key feature of this condition. However, it is not the first action to take in this scenario. While monitoring glucose levels can guide the administration of insulin and other treatments for DKA, it does not address the immediate threat posed by hypoxia.

Choice D rationale:

Administering intravenous fluids is another important step in managing DKA12. Dehydration is a common complication of DKA due to excessive urination caused by high blood sugar levels. However, similar to Choices A and C, while it is an important part of treatment, it is not the first action to take when a patient presents with both DKA and hypoxia.

Choice A rationale:

Tachycardia, or a rapid heart rate, is not typically an adverse effect of oxygen therapy. Oxygen therapy is often used to help people with conditions like COPD, COVID-19, emphysema, and sleep apnea get enough oxygen to function and stay well. While tachycardia can be a symptom of these conditions, it is not directly caused by the oxygen therapy itself.

Choice B rationale:

Cracks in the oral mucous membranes can indeed be an adverse effect of oxygen therapy. Oxygen therapy involves the delivery of highly concentrated oxygen, which can cause irritation and dryness in the airways, including the oral mucous membranes. This can lead to cracks and discomfort in the mouth. Therefore, it’s important for healthcare providers to monitor patients receiving oxygen therapy for signs of this adverse effect.

Excessive pulmonary secretions are not typically a direct adverse effect of oxygen therapy. While conditions that often require oxygen therapy, such as pneumonia and COPD, can lead to increased pulmonary secretions, these are symptoms of the underlying disease rather than the oxygen therapy itself.

Choice D rationale:

Poor skin turgor is not typically an adverse effect of oxygen therapy. Skin turgor refers to the elasticity of the skin, and poor skin turgor is often a sign of dehydration. While oxygen therapy can cause dryness of the mucous membranes, it does not typically affect the hydration status of the skin.
