A nurse is assisting with the care of a client who is placed on supplemental oxygen for hypoxia. The nurse should identify that which of the following findings indicate the intervention was effective?

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: Leakage of urine is a sign of urinary retention, as it indicates that the bladder is overdistended and unable to empty completely. The urine may leak around the urethra or through a catheter.

Choice B reason: Dark-colored urine is not a sign of urinary retention. It can be caused by dehydration, certain foods or medications, or liver or kidney problems.

Choice C reason: Cloudy urine is not a sign of urinary retention. It can be caused by infection, inflammation, or stones in the urinary tract.

Choice D reason: Blood in urine is not a sign of urinary retention. It can be caused by trauma, infection, cancer, or coagulation disorders in the urinary tract.
