A nurse is collecting data on a patient who is experiencing oxygen toxicity.
What symptoms should the nurse anticipate?

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.

Choice A rationale:

Wheezing Wheezing is typically associated with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), rather than being a symptom of hyperkalemia.

Choice B rationale:

Cerebral edema Cerebral edema, or swelling in the brain, is not typically a symptom of hyperkalemia. It’s more commonly associated with traumatic brain injury, stroke, or brain tumors.

Choice C rationale:

Decreased deep tendon reflexes Decreased deep tendon reflexes can be a symptom of hyperkalemia. Hyperkalemia is a condition in which the potassium levels in your blood get too high. Potassium helps nerves send signals between your brain and the rest of your body. High levels of potassium can affect nerve function, leading to symptoms such as muscle weakness or decreased reflexes. Choice D rationale:

Hypoactive bowel sounds Hypoactive bowel sounds, or decreased or absent bowel sounds, are typically associated with conditions affecting the gastrointestinal system, such as ileus or bowel obstruction. They are not typically a symptom of hyperkalemia.
