Chapter 26: Asepsis and Infection Control
Yoost & Crawford: Fundamentals of Nursing: Active Learning for Collaborative
Infectious agents include any disease-causing agent and are called pathogens. They include
bacteria, fungi, viruses, and parasites. Normal flora is a group of non–disease-causing
microorganisms that live in or on the body. Germ is a term used for microorganism. A
microorganism is bacteria, fungi, or protozoa. DIF: Understanding OBJ: 26.1 TOP: Assessment

4. The nurse is explaining to the patient why antibiotics are being administered. The answer
would be correct if the nurse stated antibiotics are effective against which microorganism? a. Viruses
b. Fungi
c. Parasites
d. Bacteria
ANS: D
Antibiotics are effective against bacteria, and exact antibiotic sensitivity is tested so that
appropriate antibiotics are prescribed. Infections that are caused by fungi are treated with
antifungal medications. Certain antiviral medications are used to manage the symptoms of a
viral infection. These medications, if given during the early phases of illness, can decrease the
amount of time that the patient has viral symptoms. Treatment for parasitic infections varies
depending on type of parasite. DIF: Understanding OBJ: 26.2 TOP: Teaching/Learning

5. The nurse anticipates correctly that what medication category would be ordered to
treat athlete’s foot? a. Antiviral
b. Antibiotic
c. Antihelminth
d. Antifungal
ANS: D
The nurse would expect to treat athlete’s foot with an antifungal because it is a fungal
infection. An antibiotic treats bacterial infections, antivirals treat viral infections, and
antihelminth treats parasitic worms. DIF: Applying OBJ: 26.2 TOP: Implementation

6. The nurse recognizes that the stethoscope most correctly represents which possible
link in the chain of infection? a. Source
b. Portal of exit
c. Portal of entry
d. Mode of transmission
ANS: D
The stethoscope would be a means for the pathogen to travel from source to host. The source
is the reservoir or host. The portal of exit is where the pathogen escapes from the reservoir of
infection, and the portal of entry is where the microorganism enters the susceptible host. DIF: Understanding OBJ: 26.2 TOP: Assessment
