Contact precautions mean you must wear a gown and gloves to enter. This protects you from the patient and their room.

Q: Why do doctors use broad-spectrum antibiotics for empirical therapy?

Empirical therapy is a best guess. Doctors use a drug that kills many types of germs until they know exactly what the patient has.

Q: Which factors from this list change the risk of infection? 1. Indwelling devices, 2. Staffing levels, 3. Length of stay.

Devices, enough staff, and how long a patient stays all impact infection risk. These are key medical factors.

Q: On the first day, 8 patients had an infection out of 600 total patients. What is the rate per 1,000 patients?

Divide 8 by 600. Then multiply by 1,000. The answer is 13.3.

Test 01: Isolation, Surveillance, and Safety

This initial test focuses on Contact Precautions, Outbreak Investigation, and Rate Calculations to build your certification foundation.

Contact Precautions: Healthcare workers must always wear a gown and gloves before entering the room of an isolated patient.

Rate Calculation: To find infection rates, divide the total infections by patient days and then multiply by one thousand.

Exposure Response: Following a needle stick injury, the immediate priority is washing the affected site with soap and water.
