Final answer:
The client's understanding of self-administering vancomycin is demonstrated by acknowledging the need to report changes in urine, as vancomycin can affect kidney function. Misconceptions about common side effects such as muscle tingling, weakness, and ringing in the ears should be corrected, as these are not typical and could indicate serious issues.
Step-by-step explanation:
The home health nurse is teaching a female client about self-administering vancomycin. The statement by the client that demonstrates understanding of the teaching is "I need to call my provider if my urine changes". This is because vancomycin can have nephrotoxic effects, leading to changes in kidney function reflected in the urine. It is important for the client to monitor for any signs of toxicity or adverse reactions while taking vancomycin, including changes in urine color or consistency, and to report these to the healthcare provider.
Statements such as "Muscle tingling and weakness is an expected side effect of this medication" and "Ringing in the ears is common when taking vancomycin" are not accurate. Although ototoxicity, which may cause ringing in the ears, can occur with vancomycin, it is not common and should be reported as a serious adverse effect. Similarly, muscle tingling and weakness are not typical side effects and could signify a more significant issue. The statement about avoiding food with active cultures is incorrect as well, because incorporating probiotics may actually help maintain a healthy gut flora, particularly important when taking antibiotics that can disrupt the microbial balance.
