A nurse is completing an assessment of a client who has a gastric ulcer. Which of the following findings should the nurse expect? (Select all that apply).

Choice A reason: The GFR does not recover during the oliguric phase; instead, it is typically reduced, reflecting impaired kidney function.

Choice B reason: Urine output of less than 400 mL per 24 hours is characteristic of the oliguric phase of AKI. This phase can last from 1 to 7 days after kidney injury and is a crucial time for monitoring and managing the patient's fluid and electrolyte balance.

Choice C reason: BUN and creatinine levels do not decrease during the oliguric phase. They usually increase due to reduced kidney function and the inability to excrete these waste products.

Choice D reason: Renal function is not reestablished during the oliguric phase. This phase is part of the course of AKI where renal function is at its lowest, and recovery has not yet begun.

Choice A reason: Anorexia, or loss of appetite, is not typically a direct manifestation of left-sided heart failure. While it can be associated with many medical conditions and may occur in the context of heart failure due to overall decreased well-being, it is not a specific indicator of left-sided heart failure.

Choice B reason: Weight gain can be associated with heart failure, but it is more commonly a sign of right-sided heart failure, where fluid accumulates in the body tissues, causing swelling and weight increase. In left-sided heart failure, weight gain is not as prominent because the primary issue is the backup of blood into the lungs, not fluid retention in the tissues.

Choice C reason: A distended abdomen can occur in heart failure due to fluid accumulation; however, it is more characteristic of right-sided heart failure, where the failure of the right ventricle leads to systemic congestion, including the abdominal area. In left-sided heart failure, the primary effect is on the lungs, not the abdomen.

Choice D reason: Dyspnea, or difficulty breathing, is a hallmark symptom of left-sided heart failure. It occurs due to the backup of blood in the pulmonary circulation, which leads to pulmonary congestion and reduced oxygen exchange. Patients may experience shortness of breath, especially during exertion or when lying flat (orthopnea), and may wake up at night with shortness of breath (paroxysmal nocturnal dyspnea).

Left-sided heart failure, often caused by conditions like valvular heart disease, leads to a decrease in the heart’s ability to pump blood effectively. This results in a buildup of pressure in the lungs, manifesting as dyspnea, which is an important symptom for nurses and other healthcare providers to recognize and manage promptly.
