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 A
Explanation
The statement "I realize that life must go on, but sometimes I wonder why" suggests that the client is experiencing ongoing feelings of sadness, questioning, and possibly struggling to find meaning or purpose in life after the loss of her spouse. This statement indicates a need for bereavement counseling to help the client navigate the grieving process and address the emotional challenges associated with the loss.
Correct Answer is B
Explanation
This is the first action the PN should take when noticing that the UAP consistently records subnormal temperatures when using a tympanic thermometer. Observing how the UAP obtains temperatures will help the PN identify any errors or problems with the technique, equipment, or documentation. The PN can then provide feedback and guidance to the UAP to ensure accurate and reliable temperature measurements.
