Question 13

Question
23 year old intravenous drug user, HIV-positive, on HART (antiretroviral) treatment as hospitalised in infectious department with jaundice. When taking blood for blood chemistries and hepatic markers, despite of the use of gloves nurse pricks herself with needles before disposing, together with a syringe, What's the first thing she should do?
Answer
  • Flash with water AND QUICK stop bleeding
  • Flush with water without stopping bleeding
  • Flush with water treated with a disinfectant

Question 14

Question
The results of tests made before 2 months, provided by patient are: CD4 - 451μ/L, (N 500-1300 μ/L), HIV PCR - (-). The results of blood received after 2 days are following Anti HAV IgM (+). HBsAg (-), anti HCV (+), HCV PCR (-). What is the risk to the nurse and what should be done?
Answer
  • The patient has acute hepatitis A, without much risk, controlled HIF infection, no risk of transmission
  • The patient has acute hepatitis A. without much risk. controlled HIF infection but the nurse held a 28-day course with HART, insignificant risk of hepatitis C
  • The patient has acute hepatitis A, without much risk, controlled HIF infection but the nurse held a 28-day course with HART, nevertheless monitoring tor HCV and HIF in the next six months
