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 C
Explanation
This is the priority action by the practical nurse (PN) because it can help identify and prevent a potential adverse reaction to the medication. A client who is reaching saturation with medication means that the client has reached the maximum level of medication in the blood that can produce the desired therapeutic effect. However, this also means that the client is at a higher risk of developing toxicity or side effects from the medication.
The PN should report the findings of muscle soreness, fatigue, and warm skin to the charge nurse, as these may indicate signs of inflammation, infection, or allergic reaction to the medication. The PN should also monitor the client's vital signs, oxygen saturation, and laboratory values, and document the findings. The charge nurse should notify the health care provider and adjust the medication dosage or regimen as ordered.
Correct Answer is D
Explanation
This comment by the practical nurse (PN) is likely to be the most helpful to the client. By offering to sit with the client, the PN shows empathy, support, and a willingness to provide companionship. This approach acknowledges the client's feelings of isolation and offers a listening ear. It provides an opportunity for the client to express his emotions, thoughts, or concerns if he wishes to do so. The presence of a caring and compassionate individual can help alleviate some of the client's feelings of loneliness and may encourage him to open up and engage in conversation or activities when he is ready.
A. "Come into the recreation area. We have your favorite card game and I will play it with you."
This choice assumes that engaging in a specific activity will automatically help the client and solve his current feelings of reclusiveness. While offering an activity may be beneficial in some cases, it is important to first address the client's emotional state and provide support before suggesting specific activities. Pushing the client to participate in an activity without acknowledging his current feelings may further alienate him and not address the underlying issues causing his reclusive behavior.
B. "Why do you want to stay in your room today?"
This choice may come across as confrontational or judgmental. Asking why the client wants to stay in his room implies that there is something wrong with his decision or that he needs to justify his behavior. This approach may make the client defensive or withdraw further. It is essential to create a safe and supportive environment where the client feels understood and validated, rather than questioning his choices.
C. "I know you are sad about not seeing your family as often, but they are visiting as much as they can."
While acknowledging the client's sadness about not seeing his family is important, dismissing his feelings by stating that his family is visiting as much as they can minimize or invalidate his emotions. It is crucial to provide empathy and validate the client's emotions without making assumptions or downplaying his experiences. This approach may not address the client's current state of reclusiveness or provide the support he needs.
