A nurse is collecting data on a client who has oxygen toxicity. Which of the following findings should the nurse expect?

Choice A reason: Tachycardia is not an adverse effect of oxygen therapy. Tachycardia is a condition where the heart rate is faster than normal, usually above 100 beats per minute. Tachycardia can be caused by various factors, such as fever, infection, pain, or anxiety. Tachycardia can also be a sign of hypoxemia, which is a low level of oxygen in the blood, and may indicate the need for oxygen therapy.

Choice B reason: Cracks in oral mucous membranes are an adverse effect of oxygen therapy. Cracks in oral mucous membranes are a sign of dryness and irritation caused by the oxygen flow. Oxygen therapy can reduce the natural moisture and lubrication of the mouth and nose, leading to discomfort and increased risk of infection. To prevent or treat this problem, the nurse should provide the client with humidified oxygen, oral care, and hydration.

Choice C reason: Excessive pulmonary secretions are not an adverse effect of oxygen therapy. Excessive pulmonary secretions are a sign of inflammation and infection in the lungs, which can impair gas exchange and cause coughing, wheezing, and dyspnea. Excessive pulmonary secretions can be a symptom of pneumonia, which is a common cause of respiratory failure and may require oxygen therapy.

Choice D reason: Poor skin turgor is not an adverse effect of oxygen therapy. Poor skin turgor is a sign of dehydration, which is a loss of fluid from the body. Dehydration can be caused by various factors, such as vomiting, diarrhea, fever, or inadequate intake. Dehydration can affect the blood volume and pressure, and may worsen the oxygen delivery to the tissues. To prevent or treat this problem, the nurse should monitor the client's fluid balance and provide adequate hydration.

Choice A reason: Spinach is a good source of potassium, but not the best. According to the USDA, one cup of cooked spinach contains 839 mg of potassium, which is about 18% of the recommended daily intake (RDI) for adults².

Choice B reason: Baked potato is the best source of potassium among the choices. According to the USDA, one medium baked potato with skin contains 941 mg of potassium, which is about 20% of the RDI for adults². Potassium is an essential mineral that helps regulate fluid balance, nerve and muscle function, and blood pressure.

Choice C reason: Banana is a popular source of potassium, but not the best. According to the USDA, one medium banana contains 422 mg of potassium, which is about 9% of the RDI for adults².

Choice D reason: Cheese is a poor source of potassium. According to the USDA, one ounce of cheddar cheese contains only 28 mg of potassium, which is less than 1% of the RDI for adults². Cheese is high in sodium, which can counteract the benefits of potassium and increase the risk of hypertension.
