Canadian RN Exam:
Answers and Rationale

1) D - Correct
Rationale: hepatitis B virus may spread through blood and body fluids during unprotected sex

A - Incorrect
Rationale: hepatitis A, and not hepatitis B, is transmitted through contaminated water

B - Incorrect
Rationale: alcohol misuse does negatively affect the liver, but it does not promote the transmission of hepatitis B

C - Incorrect
Rationale: hepatitis B is not transmitted through the fecal-oral route

2) C - Correct
Rationale: utmost care must be taken in handling syringes, needles and other instruments that are contaminated with body fluids

A - Incorrect
Rationale: hepatitis B virus is not transmitted via the fecal-oral route

B - Incorrect
Rationale: this response would only be appropriate if the person were bleeding, as the hepatitis B virus can live outside the body for few hours. Otherwise, private washrooms are not necessary

D - Incorrect
Rationale: this is not the most effective nursing intervention for transmission prevention. Hepatitis B is transmitted via body fluids, not air

3) B - Correct
Canadian RN Exam Rationale: Mr. White's current state of fatigue warrants a balance between periods of activity and rest
