Which medication is commonly used in the treatment of multiple sclerosis?

A. This action is crucial if there is a suspicion of elder abuse, as adult protective services (APS) can investigate the situation thoroughly and take necessary measures to protect the client. However, before making such a notification, it is important to assess the immediate safety of the client and gather preliminary information.
B. This is a prudent initial action to ensure that the client is in a safe environment away from the caregiver, who may be the suspected abuser. It allows the nurse to conduct a private and thorough assessment of the client without the potential influence or intimidation from the caregiver. This step is critical for ensuring the client's safety and obtaining unbiased information.
C. While reporting to the caregiver’s employment agency may be a step in the process, it is not the immediate priority. The primary focus should be on ensuring the client’s safety and assessing the situation before contacting external agencies.
D. While it is important to gather information about how the injury occurred, the immediate priority is to ensure the client's safety and provide an opportunity for a private assessment. The presence of the caregiver during this conversation could influence the client's responses or cause additional stress.

A. Elevated potassium levels (hyperkalemia) can occur in chronic kidney disease, as the kidneys struggle to excrete potassium. However, hyperkalemia does not typically cause visible crystals on the skin. It is more associated with cardiac arrhythmias and muscle weakness rather than skin manifestations.
B. Sodium imbalance is common in chronic kidney disease, often leading to fluid retention and hypertension. However, excess sodium does not result in crystal formation on the skin. Sodium issues are more related to fluid balance and blood pressure, not external crystalline deposits.
C. Urea is a waste product formed from the breakdown of proteins and is normally excreted by the kidneys. In chronic kidney disease, urea accumulates in the blood (uremia) because the kidneys cannot effectively filter it out. Urea can be deposited on the skin and form crystals, leading to a condition known as "uremic frost." This is often observed on the forehead or other areas of the skin and is a direct result of excess urea in the body.

D. Creatinine is another waste product filtered by the kidneys. Elevated levels indicate impaired kidney function, but creatinine itself does not form visible crystals on the skin. Elevated creatinine levels are primarily used as an indicator of kidney function rather than a cause of external skin manifestations.
