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: Lactated Ringer’s

Lactated Ringer’s solution is an isotonic crystalloid that contains electrolytes similar to those found in blood plasma. While it is commonly used for fluid resuscitation, it does not provide a significant source of calories and therefore is not the best option to temporarily replace TPN.

Choice B: 0.9% sodium chloride

0.9% sodium chloride, also known as normal saline, is an isotonic solution that is used to expand volume and correct electrolyte imbalances. Like Lactated Ringer’s, it does not contain a significant amount of calories and is not suitable as a temporary replacement for TPN.

Choice C: 3% sodium chloride

3% sodium chloride is a hypertonic saline solution used in controlled settings to treat specific conditions such as hyponatremia. Due to its high concentration of sodium, it is not appropriate for routine fluid replacement and does not provide calories.

Choice D: Dextrose 10% in water

D10W is the preferred choice in this scenario because it provides a source of glucose, which can help maintain blood glucose levels when TPN is not available. It is important to monitor the patient’s blood glucose levels while infusing D10W to ensure they remain within a safe range. When a TPN container is delayed, Dextrose 10% in water is the most appropriate temporary solution to infuse until the next container becomes available, as it provides necessary calories in the form of glucose to the patient.
