A male client with acute kidney injury (AKI) is scheduled for his first hemodialysis treatment and asks the practical nurse (PN) how the treatments will be evaluated for effectiveness. The PN explains that blood samples will be collected for analysis. Which laboratory value should the PN explain as the best indicator of each hemodialysis?
Elevated potassium.
Decreased calcium.
Lowered hemoglobin.
Decreased creatinine.
The Correct Answer is D
Hemodialysis is a procedure used to remove waste products and excess fluid from the blood when the kidneys are unable to function properly. One of the waste products that accumulate in the blood during kidney dysfunction is creatinine. Creatinine is a byproduct of muscle metabolism, and its levels in the blood are normally regulated and eliminated by the kidneys. In AKI, the kidneys are not able to effectively filter and eliminate creatinine, leading to elevated levels in the blood. Hemodialysis helps to remove excess creatinine from the blood, resulting in decreased creatinine levels.
A- Elevated potassium levels (hyperkalemia) are common in AKI and can be life-threatening. Hemodialysis helps to remove excess potassium from the blood, restoring normal levels.
However, the best indicator of the effectiveness of hemodialysis in managing hyperkalemia would be monitoring the potassium levels before and after the session rather than considering it as the "best" indicator.
B- Decreased calcium levels can occur in kidney dysfunction due to impaired activation of vitamin D and decreased absorption of calcium from the intestines. While hemodialysis can help restore calcium levels, it may not be the primary laboratory value used to evaluate the effectiveness of each session.
C- Lowered hemoglobin levels can be seen in AKI due to various factors, including decreased production of red blood cells and blood loss. Hemodialysis can help remove waste products and excess fluid, but it may not directly address the underlying causes of lowered hemoglobin levels.

Correct Answer is B
Explanation
A. Using a cushion when sitting may provide comfort, but it does not directly address the client's elevated blood pressure or changes in mental status related to chronic kidney disease (CKD).
B. Weighing every morning is crucial in managing CKD, particularly with elevated blood pressure, as it helps monitor fluid retention, which can indicate worsening kidney function or fluid overload. This intervention is essential for assessing the client's condition and adjusting treatment as needed.
C. Performing range of motion exercises is important for maintaining mobility, especially in an immobile client; however, it does not directly address the pressing issues of elevated blood pressure and altered mental status.
D. Documenting abdominal girth can be important for assessing fluid retention, but it is less immediate than daily weight monitoring for a client with CKD showing significant symptoms.
Correct Answer is C
Explanation
Heart rate of 90 beats per minute with premature ventricular contractions (PVCs) noted on telemetry: This finding indicates an abnormality in the heart's electrical conduction system. PVCs are extra, abnormal heartbeats that originate in the ventricles. They can sometimes be benign, but they can also be associated with underlying heart conditions or electrolyte imbalances. Since the client is experiencing dizziness and tingling, which could be related to cardiac function, it is important to report this finding to the healthcare provider for further evaluation and appropriate management.
Incorrect:
A. Regular heart rate of 100 beats per minute on telemetry: This finding describes a heart rate within the normal range (60-100 beats per minute for adults). It does not indicate any immediate concerns or abnormalities that would require reporting to the healthcare provider in this context.
B. Hypoactive bowel sounds on assessment: Following a small bowel resection, it is common for bowel sounds to be temporarily reduced or absent due to the surgical manipulation and the bowel's response to anesthesia. Hypoactive bowel sounds alone do not directly relate to the client's reported symptoms of dizziness and tingling in digits, nor do they suggest an immediate need for reporting to the healthcare provider.
D. Hyperactive bowel sounds on assessment: Hyperactive bowel sounds, characterized by increased loudness and frequency, can occur due to conditions such as gastroenteritis or bowel obstruction. However, in the context of a client who has undergone a small bowel resection and is on NPO status, hyperactive bowel sounds would not be expected and may indicate a potential complication. While it is important to monitor and document this finding, it is not directly related to the client's reported symptoms and does not require immediate reporting to the healthcare provider in this scenario.
