The practical nurse (PN) selects the ventrolateral site to administer an intramuscular (IM) injection to an adult. Identify the Injection site.

A callus is a normal response of the body during bone healing, where new bone tissue forms around the fracture site to provide stability and support. It helps in the process of bridging the fracture and promoting healing.
The PN can provide reassurance to the client by explaining that the presence of a callus indicates that the bone is healing and progressing toward recovery. It is important to educate the client about the expected timeline for bone healing and the need for continued follow-up with the healthcare provider.
Incorrect:

A. Prepare to assist in applying a new cast to reduce pressure points: This choice assumes that the client's concern is related to discomfort or pressure points caused by the current cast.
However, the client's concern is about the formation of a callus, which is a normal part of bone healing. There is no indication that a new cast is necessary at this point.
B. Report the client's concern to the healthcare provider: While it's important to address client concerns and communicate any changes in their condition to the healthcare provider, in this case, the formation of a callus is an expected part of the bone healing process. It is not necessary to report this concern to the healthcare provider as it is a normal occurrence.
D. Teach the client strategies to prevent further calluses: The formation of a callus in this context is a natural response of the body to promote bone healing. It is not necessary to teach the client strategies to prevent further calluses, as callus formation is a temporary and beneficial part of the healing process.

This is the correct answer because BUN and creatinine are the most important laboratory values to monitor for nephrotoxicity, which is the damage or injury to the kidneys caused by certain drugs or chemicals.
Nephrotoxicity can impair the kidneys' ability to filter waste products from the blood, resulting in elevated levels of BUN and creatinine. The normal range for BUN is 7 to 20 mg/dL, and for creatinine is 0.6 to 1.2 mg/dL. The practical nurse (PN) should review these values before administering an antibiotic that can cause nephrotoxicity, such as aminoglycosides, cephalosporins, vancomycin, or sulfonamides. The PN should also monitor the client for signs and symptoms of nephrotoxicity, such as decreased urine output, edema, hypertension, fatigue, nausea, and confusion.
