Chapter 16: Infection Prevention and Control: Protective Mechanisms and Asepsis
Williams: deWit's Fundamental Concepts and Skills for Nursing, 5th Edition
MULTIPLE CHOICE
1. When a patient in the ambulatory clinic is diagnosed as having pneumococcal pneumonia,
the nurse is aware that this infection:
a. is viral and will not respond to antibiotics.
b. is bacterial and should respond to treatment with antibiotics.
c. is fungal and is caused by the alteration of the normal flora of the lung.
d. is resultant from a resistant organism and extreme caution must be taken.
ANS: B
The coccal suffix indicates a bacterial infection with round cocci, which are bacteria that
usually respond to antibiotic therapy.

2. The nurse explains to the patient who has pneumococcal pneumonia that the lungs serve as
the:
a. mode of transfer.
b. transmission of the disease.
c. reservoir.
d. organisms that cause the infection.
ANS: C
The reservoir is the place where the organism is found, such as a wound or, in this case, the
infected lungs. Droplets are modes of transmission from the reservoir.

3. The patient inquires about how his body will kill pathogens unassisted by antibiotics. The
nurse responds that a process called phagocytosis will:
a. stimulate the body to make more white blood cells.
b. create antibodies against the pathogen.
c. engulf and destroy the pathogen.
d. stimulate the production of interferons.
ANS: C
Phagocytes that are stored in the GI tract, liver, and spleen kill pathogens by engulfing and
destroying the invaders and cleaning up the debris.

4. The nurse explains that the immunizations against hepatitis B will:
a. stimulate the body to make antibodies the hepatitis B antigen.
b. offer immediate protection from hepatitis B by the injection of ready-made
antibodies.
c. introduce live antigens into the body that will stimulate the production of
antibodies.
d. offer protection against hepatitis A, C, and D, in addition to hepatitis B.
ANS: A
Artificially acquired immunization is achieved by introducing killed or attenuated pathogens
that are recognized as antigens by the immune system but that are not able to cause disease.
These antigens stimulate the formation of antibodies specific to hepatitis B only.

5. A mother and her 2-week-old infant, who is breastfed, have been exposed to chicken pox.
Although the mother had chicken pox as a child, she is concerned about her baby. The nurse
explains:
a. the infant is at risk because the baby has not been immunized against the disease.
b. both infant and mother are at risk because the mother’s immunity was acquired too
long ago to be effective.
c. the baby should receive immune globulin to protect him from the infection.
d. neither are at risk, because the mother has naturally acquired immunity, and she
passes antibodies to the baby through the breast milk.
ANS: D
Having had a disease such as chicken pox provides lifelong naturally acquired immunity,
which allows the mother to pass on antibodies through the placenta and breast milk to
protect the infant until his immune system is more mature.

6. Health personnel should wash their hands with soap and water at the beginning of the shift
for:
a. 10 seconds.
b. 15 seconds.
c. 1 minute.
d. 2 minutes.
ANS: B
Hand hygiene as suggested by the CDC should be done at the beginning of the shift for 15
seconds (30 seconds or longer in specialty areas).
