A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with increased shortness of breath and a productive cough. The nurse notes the client’s oxygen saturation is 88% on room air. Which of the following interventions should the nurse implement first?
Administering supplemental oxygen.
Encouraging the client to use an incentive spirometer.
Administering a bronchodilator as prescribed.
Positioning the client in high Fowler’s position.
The Correct Answer is A
Choice A rationale
Administering supplemental oxygen is the priority intervention for a client with COPD who has an oxygen saturation of 88% on room air. This low oxygen saturation indicates hypoxemia, which requires immediate correction to prevent further respiratory distress.
Choice B rationale
Encouraging the client to use an incentive spirometer is important for lung expansion and preventing atelectasis, but it is not the priority intervention in this scenario. The immediate concern is to correct the hypoxemia.
Choice C rationale
Administering a bronchodilator as prescribed is important for managing COPD symptoms, but the priority intervention is to correct the hypoxemia by administering supplemental oxygen.
Choice D rationale
Positioning the client in high Fowler’s position can help improve breathing, but the priority intervention is to correct the hypoxemia by administering supplemental oxygen.

Correct Answer is A
Explanation
Choice A rationale
A hypertensive crisis is characterized by severely elevated blood pressure, which can cause severe headache and blurred vision due to increased intracranial pressure.
Choice B rationale
Migraines can cause severe headaches and visual disturbances, but in a patient with a history of hypertension, a hypertensive crisis is more likely.
Choice C rationale
Sinus infections can cause headaches and facial pain, but not typically blurred vision.
Choice D rationale
Gastroenteritis causes gastrointestinal symptoms like diarrhea and vomiting, not headaches and blurred vision.
Correct Answer is A
Explanation
Choice A rationale
Elevated blood ammonia levels are a common consequence of liver dysfunction, particularly in conditions like cirrhosis and alcoholic liver disease. The liver is responsible for converting ammonia, a byproduct of protein metabolism, into urea, which is then excreted by the kidneys. When the liver is damaged, it cannot effectively perform this function, leading to elevated blood ammonia levels. High ammonia levels can cross the blood-brain barrier and cause hepatic encephalopathy, which manifests as confusion, memory loss, and asterixis (a flapping tremor of the hands). These neurological symptoms are consistent with the patient’s presentation.
Choice B rationale
An increased white blood cell count typically indicates an infection or inflammation. While infections can occur in patients with liver disease due to a compromised immune system, the symptoms described (increased blood glucose, blurred vision, memory loss, and asterixis) are more indicative of hepatic encephalopathy rather than an infection.
Choice C rationale
Elevated blood urea nitrogen (BUN) levels can occur in liver disease, but they are more commonly associated with kidney dysfunction. BUN is a measure of the amount of nitrogen in the blood that comes from the waste product urea. While liver dysfunction can affect BUN levels, the symptoms described are more specifically related to elevated ammonia levels and hepatic encephalopathy.
Choice D rationale
A decreased platelet count, or thrombocytopenia, is a common finding in liver disease due to splenic sequestration and decreased production of thrombopoietin. However, thrombocytopenia does not directly cause the neurological symptoms described in the patient. The symptoms of increased blood glucose, blurred vision, memory loss, and asterixis are more specifically related to elevated ammonia levels and hepatic encephalopathy.
