A nurse is collecting data on a client who has mitral valve stenosis. 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: This statement indicates a need for further teaching, as it is incorrect. The client does not need to catheterize the stoma, as the urine flows continuously from the ileal conduit to the pouch. Catheterization can cause infection and damage to the stoma.

Choice B reason: This statement is correct, as the client will need to measure the stoma each week for the first 6 to 8 weeks after surgery. The stoma may change in size and shape as it heals, and the client will need to adjust the size of the pouch opening accordingly.

Choice C reason: This statement is correct, as the client will always have to wear a pouch to collect the urine. The client can choose from different types of pouches, such as one-piece or two-piece systems, and change them as needed.

Choice D reason: This statement is correct, as the client will need to cleanse around the stoma with soap and water at least once a day. This helps to prevent skin irritation and infection. The client should avoid using alcohol, perfumes, or lotions on the stoma.
