A male client attends a community support program for mentally impaired and chemical-abusing clients. The client tells the practical nurse (PN) that his drugs of choice are cocaine and heroin. What is the greatest health risk for this client?

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.

The most important intervention for the practical nurse (PN) to implement when applying an ice pack to a client is to secure a protective cover over the bag. This is essential to protect the client's skin from direct contact with the ice pack, which can cause tissue damage, frostbite, or discomfort.
Securing a protective cover, such as a thin cloth or towel, between the ice pack and the client's skin helps to create a barrier and prevent excessive cold exposure. It allows for the therapeutic benefits of the ice pack, such as reducing swelling and pain, while minimizing the risk of skin damage.
Incorrect:

A. While wrapping the bag in place for comfort is important, it is not the most critical intervention compared to ensuring the protection of the client's skin.
C. Giving directions to leave the pack in place is a general instruction for the client to follow the prescribed treatment, but it does not specifically address the importance of using a protective cover.
D. The type of ice used, whether crushed or cubed, may vary based on availability and preference, but it does not take precedence over the need to protect the client's skin with a cover.
