A nurse is teaching a client who has acute kidney injury (AKI) about the oliguric phase. Which of the following information should the nurse include in the teaching?
The glomerular filtration rate (GFR) recovers.
Urine output is less than 400 mL per 24 hours.
BUN and creatinine levels decrease.
Renal function is reestablished.
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A reason:Cardiac enzyme studies do not provide information about the heart's structure or the mobility of the heart valves; imaging studies are used for that purpose.
Choice B reason:While cardiac enzymes indicate damage to heart tissues, they do not pinpoint the exact location of an MI; imaging studies are needed for localization.
Choice C reason:Cardiac enzymes are not used to diagnose pulmonary congestion; they are specific markers for myocardial injury.
Choice D reason:Cardiac enzyme levels, such as troponin, rise when there is damage to the heart muscle, which is why they are used to assess the degree of damage after an MI.
Correct Answer is A
Explanation
Choice A reason:Taping the connections on the client's chest tube is essential to maintain a closed system and prevent air leaks, which could lead to a pneumothorax.
Choice B reason:Positioning the client in a supine position is not recommended as it may not facilitate optimal drainage from the pleural space.
Choice C reason:Stripping the chest tube, which involves applying pressure and sliding the fingers down the tube to remove clots, is not routinely recommended as it can generate high negative pressures and damage lung tissue.
Choice D reason: The chest tube drainage system should be placed below the level of the client's heart to allow for gravity drainage of pleural fluid and air.
