Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose.

Rationale: Exenatide, a medication commonly used in type 2 diabetes, is known to cause gastrointestinal side effects, such as nausea. Monitoring for nausea is essential as it can lead to decreased appetite and potential weight loss, affecting the nutritional status of the client. While hypoglycemia and hyperglycemia are important to monitor in diabetes management, they are not typically associated with exenatide use. Pancreatitis is a rare but serious adverse effect of exenatide, which requires immediate medical attention if suspected.

Hemoglobin levels serve as a direct indicator of the response to treatment and improvement in the condition. An increase in hemoglobin level to 12 grams/dL suggests that the medication is effectively addressing the anemia associated with CKD.
