Q1 An IP was asked to provide infection prevention consultation to a long-term care facility LTCF. As a part of this consultation, she checks to make sure which of the following program component are in place : 1- Decolonizing residents with MRSA. 2- Establishing AB Stewardship program. 3- Implementing an annual influenza vaccination program. 4- Collecting environmental cultures of high-touch areas. a- 1,2. b- 2,3. c- 3,4. d- 1,4.

Answer : (B) 2,3. Rationale : Antibiotic resistance continue to pose a significant problem for residents in LTCF because of the overuse and misuse of the AB. AB stewardship refer to coordinated interventions designed to improve and measure the appropriate use of AB by promoting the selection of the optimal AB drug regimen, dose, duration of the therapy and route of administration. The IDSA and SHEA support broad implementation of AB stewardship program across healthcare setting including LTCF. In addition, it is recommended that flue vaccine be provided to all residents of LTCF. Influenza outbreak in LTCF may have severe and even deadly consequences for residents. Because Flue is easily transmitted, it is important that flue vaccination is offered to all residents to provide both individual protection and "herd immunity" (i.e. group protection)in the LTCF. Research has shown greater effectiveness of flue vaccine program among the geriatric and population and long-term care residents.

Q2 In a study of whether Operation room A (ORA) is associated with a higher number of surgical site infection (SSI) than Operation room B (ORB). The IP is testing whether: H0 : OR A SSI rate = OR B SSI rate Ha : OR A SSI rate ≠ OR B SSI rate The IP concludes that SSI rate in OR A is not equal to the SSI rate in OR B, but in reality the two rates are equal . what type of error has she committed: a- No Error has been committed. b- She committed type I error. c- She committed type II error. d- She committed an error equal to β.

Answer : (B) type I error Rationale : If the IP concluded that the SSI rate in OR A is not equal to the SSI rate in OR B then she rejected the null hypothesis. However, in this case the null hypothesis was true; therefore she has committed error type I, the value equal to α.

Q3 When are the IgM AB to hepatitis A virus (HAV) detectable in the blood: a- 30 days after exposure. b- 5 -10 days after exposure. c- 1- 4 days after exposure. d- 15-20 days after exposure.

Answer : (B) 5- 10 days after exposure Rationale: hepatitis A is an acute liver disease caused by HAV. Clinical features of the illness are not specific for HAV infection, so serological diagnosis is necessary, IgM AB to HAV (IgM anti-HAV) , which are used to diagnose acute HAV infection, are detectable within the first 3 weeks of exposure and are present at onset of jaundice. Titer declines over 4-6 weeks and AB are usually not detectable after 6-12 months. IgG anti-HAV is also detectable at the onset of jaundice, but it remain life long, indicating immunity to HAV.
