A nurse has identified a fluid volume deficit in the patient who has suffered prolonged vomiting and diarrhea.

Which assessment data is most important in identifying that the patient may be developing prerenal acute kidney injury (AKI)?

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.

Choice A rationale
Sepsis is a systemic inflammatory response to infection, often characterized by fever (temperature of 38°C or higher) and tachycardia (heart rate of 120 beats per minute or higher). These symptoms indicate the body’s response to a severe infection.
Choice B rationale
Hypovolemic shock is caused by significant fluid loss, leading to decreased blood volume and perfusion. It typically presents with hypotension and tachycardia, but not necessarily fever.
Choice C rationale
Myocardial infarction (heart attack) is characterized by chest pain, shortness of breath, and other symptoms, but fever and tachycardia are not primary indicators.
Choice D rationale
Pulmonary embolism involves a blockage in the pulmonary arteries, leading to symptoms such as sudden shortness of breath, chest pain, and rapid heart rate, but not typically fever.
