9 Questions
Which of the following is a key factor contributing to high mortality in septic shock?
Kidney failure
Which of the following is true about the q-SOFA scale?
It is used to identify patients at higher risk of poor outcomes due to suspected infection
What is the recommended course of action for infants born to mothers with acute hepatitis B?
A full course of hepatitis B vaccine and hepatitis B immunoglobulin should be given
Which of the following is NOT an example of a disease vector?
Ants
What is the primary mode of transmission for malaria?

Study Notes
Key Points about Infectious Diseases
- The q-SOFA scale has 3 elements and is used to identify patients at higher risk of poor outcomes due to suspected infection.
- Patients with two or more q-SOFA criteria are considered to have increased risk of poor outcomes in suspected infection.
- Septic shock is primarily caused by multiple organ failure, resulting from a dysregulated immune response to an infection.
- Dysfunction of multiple organs, including heart, lungs, kidneys, and liver, contributes to high mortality in septic shock.
- Laboratory tests for liver failure include albumin level and INR/prothrombin time, which reflect the synthetic function of the liver.
- Total anti-HBc antibodies persist for many years after elimination of HBsAg and indicate previous HBV infection.
- Hepatitis E virus infection is typically transmitted through contaminated water or food, not intravenous route, and is dangerous for women in the 3rd trimester of pregnancy.
- There is no vaccine against Hepatitis C.
- Infants born to mothers with acute hepatitis B should receive a full course of hepatitis B vaccine and hepatitis B immunoglobulin to maximize protection and reduce transmission risk.
- Hepatitis B immunoglobulin provides immediate passive immunity by providing protective antibodies against the virus.
- The full course of hepatitis B vaccine is given to provide active immunity against the hepatitis B virus.
- Total anti-HBc antibodies alone cannot distinguish between a resolved infection and ongoing chronic infection.
