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 D
Explanation
When a client expresses fear and uncertainty about undergoing surgery, it is important for the practical nurse (PN) to communicate this information to the charge nurse or the healthcare provider. By notifying the appropriate person, the PN ensures that the client's concerns are addressed and appropriate interventions can be implemented.
Options a) and c) are not the priority actions because documenting the client's concerns or reminding them about the signed consent does not address their emotional needs or provide support.
Option b) may not be the most appropriate response, as simply encouraging the client to continue with the scheduled surgery without addressing their fears and uncertainties may not be sufficient to alleviate their anxiety.
Therefore, the best course of action is to notify the charge nurse or healthcare provider so that they can assess the client's concerns, provide reassurance, and address any questions or fears the client may have prior to the surgery.
Correct Answer is A
Explanation
The appropriate action for the practical nurse (PN) in this situation would be to ask the client if he is currently hearing voices. This step is important to assess the client's current state and gather information about his experiences. By directly asking the client about hearing voices, the PN can gain insight into the client's symptoms and determine if there is a need for further intervention or support.
B. Having the unlicensed assistive personnel (UAP) escort the client to his room may not be necessary at this point, as the client may simply be engaging in self-talk or may prefer some time alone. However, if the client's behavior becomes disruptive, agitated, or poses a safety risk, involving the UAP or taking other appropriate measures may be warranted.
C. Recording the event is important for documentation purposes, but it should not be the only action taken. It is crucial to actively assess the client's well-being and address any potential concerns or needs.
D. Administering an as-needed (PRN) dose of haloperidol without further assessment or consulting the healthcare provider would be inappropriate. Medication decisions should be based on a comprehensive evaluation of the client's symptoms and the healthcare provider's recommendations.
