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
When a preoperative client expresses fear and uncertainty about undergoing surgery, the priority action for the practical nurse (PN) is to notify the charge nurse of the client's concerns. This is important because the charge nurse can coordinate appropriate interventions and support for the client, ensuring their emotional well-being and addressing their fears.
Correct Answer is B
Explanation
This is the correct answer because it is the best way to assess for signs of ototoxicity, which is a potential adverse effect of aminoglycosides. Ototoxicity is the damage or injury to the inner ear or auditory nerve caused by certain drugs or chemicals. It can result in hearing loss, tinnitus, vertigo, or balance problems. Aminoglycosides are a class of antibiotics that are effective against gram-negative bacteria, but they can also cause ototoxicity by interfering with the function of the hair cells in the cochlea.
The practical nurse (PN) should monitor the client's hearing by asking about any changes in hearing acuity, ringing in the ears, or difficulty understanding speech. The PN should also perform a hearing test using a tuning fork or an audiometer if available. The PN should report any signs of ototoxicity to the healthcare provider and discontinue the aminoglycoside as ordered.
