RAD 105 EXAMINATION QUESTIONS
WITH HIGH SCORING ANSWERS
Factors That Encourage Nosocomial Infections - Answer- Environment
Therapeutic regimen
Equipment
Contamination during medical procedures
Factors Increasing Potential for Nosocomial Infections - Answer- Age
Heredity
Nutritional status
Stress
Inadequate rest or exercise
Personal choice habits
Health history
Inadequate defenses
Bloodborne pathogens - Answer- Disease-causing microorganisms carried in the body
by blood or body fluids, such as hepatitis and HIV.
Considered nosocomial
Others that aren't as prevalent are:
Hep C, Hep D, and Syphilis
HIV - Answer- A virus that attacks and destroys the human immune system.
Responsible for acquired immunodeficiency syndrome (AIDS)
Symptoms: weight loss, muscle and joint pain, glandular pain and swelling, night sweats
May be asymptomatic after exposure to HIV for as long as 10 years
May take up to 1 year for results of blood test to become positive for HIV antibodies
HBV - Answer- hepatitis B virus
Primarily affects liver, resulting in swelling, soreness, and loss of normal function of liver
Symptoms: weakness, fatigue, anorexia, nausea, abdominal pain, fever, and headache
Leads to yellow skin color (jaundice)
Some patients are asymptomatic.
Blood will test positive 2 to 6 weeks after symptoms develop.
Patients can recover in 6 to 8 weeks, but blood tests will always show they were
exposed.

Sterilization
Autoclave
The human body has _______ ,________ , and _______ mechanisms that it uses to
fight infection. - Answer- mechanical, cellular, and chemical
A pacemaker prevents bradycardia by:
1. sensing the patient's heartbeats.
2. pacing the heart when it does not contract.
