Part of the Medical Emergencies practice questions exam area.
This page holds 200 free practice questions for Chapter 27, Infectious Diseases, covering microbiology and the chain of infection, infection control, PPE, and exposure reporting, HIV and hepatitis, tuberculosis, influenza, COVID-19, and other respiratory infections, vaccine-preventable childhood diseases, meningitis, rabies, and tetanus, sepsis and septic shock, and MRSA, C. difficile, STIs, and tick-borne disease. They are written for paramedic and EMT students working through Nancy Caroline's Emergency Care in the Streets, 9th edition. Every question shows the correct answer with a short explanation as soon as you tap, so you learn while you test rather than waiting until the end.
Study it two ways: the 10 Question Blitz, a quick round where every right answer lights a siren and any misses lead into Lights & Sirens, a 5-in-a-row drill on that section, or the full 100-question test drawn at random from the whole chapter. After each test you get a score and a section-by-section breakdown. Progress on the full test is saved on your device, so you can stop and pick up later.
Several picnic guests start vomiting 2 hours after eating potato salad left in the sun. The very short onset suggests:
Answer: A. A toxin already formed in the food
Symptoms within a few hours point to a preformed toxin, such as Staphylococcus aureus toxin in food left warm. Infections that must multiply in the body, viruses spreading between people, or parasites take a day or more to cause illness. Treatment is supportive, with attention to dehydration.
During care of a patient with suspected Ebola, a trained observer watches each provider remove PPE. The main reason is to:
Answer: A. Catch self-contamination during doffing
Removing PPE is when most self-contamination happens. A trained observer reads a checklist step by step and watches for breaches so they can be corrected immediately. It is not for timing, supply counts, or charting.
The risk of HIV infection after a needlestick from an HIV-positive patient is about:
Answer: D. 0.3%
The risk is much lower than for hepatitis B. PEP reduces it further.
Most students use the 10 Question Blitz for daily practice and take the full 100-question test in the days before a class exam or NREMT practice. Lights & Sirens after a blitz is the fastest way to close gaps the night before a test.
Every question in this chapter is also listed by section, with answers, on the topic pages above. See all paramedic topics or take the NREMT paramedic practice test.
