Final answer:
Routine follow-up for a 22-year-old woman on Isotretinoin therapy includes monitoring hepatic enzymes, triglyceride levels, and ensuring the absence of pregnancy but not necessarily platelet count, which is not generally affected by this medication.
Step-by-step explanation:
In a 22-year-old woman using Isotretinoin (Accutane) therapy, the Nurse Practitioner (NP) ensures follow-up to monitor all of the following except platelet count. Isotretinoin is a medication used to treat severe acne that can have multiple systemic side effects. Therefore, healthcare providers must monitor patients for potential adverse effects. Specifically, hepatic enzymes and triglyceride measurements are checked routinely because isotretinoin can affect liver function and elevate triglyceride levels, which may increase the risk of pancreatitis. Additionally, due to its high teratogenicity, it is essential that the patient is not pregnant and takes precautions against pregnancy while on isotretinoin. Pregnancy must be avoided and is checked consistently because of the risk of severe birth defects associated with isotretinoin. However, routine monitoring of the platelet count is not generally necessary unless the patient presents specific clinical indications.
