Feedback
1 Mumps is transmitted by droplet infection from a cough or a sneeze.
2 Polio enters the body through a fecal-oral route from contaminated food.
3 Herpes simplex is transmitted through close skin contact.
4 West Nile virus is spread through mosquito bites.
Feedback
1 Enterobiasis is a helminth infection caused by pinworms.
2 Creutzfeldt-Jakob disease is caused by a prion.
3 Giardiasis is caused by a protozoan called Giardia lamblia.
4 Coccidiomycosis is a fungal infection.
Feedback
1 Staphylococcus saprophyticus normally colonize the skin, and are not antibiotic
resistant.
2 With widespread use of antibiotics, Staphylococcus aureus strains are found to be
methicillin resistant and vancomycin resistant.
3 Streptococcus pyogenes is not antibiotic resistant.
4 Streptococcus viridans is not antibiotic resistant.
Feedback
1 Abdominal pain is not a sign of meningitis as it does not affect the gastrointestinal
organs.
2 Nuchal rigidity or stiffness in the neck is a symptom of meningitis and can be confirmed
as Kernig’s and Brudzinski signs.
3 Sensitivity to sound is not a key sign of meningitis.
4 Dysuria is a sign of urinary tract infection, not meningitis.
Feedback
1 Leishmaniasis is spread through sandflies. Therefore, using insect repellant to repel
sandflies is one of the preventive measures.
2 There are no vaccines against leishmaniasis.
3 Avoiding vector-infested areas will not help those who mandatorily have to live in the
area, such as soldiers in the Persian Gulf in whom the disease is common. Besides,
Feedback
1 Tissue sampling is used to confirm leishmaniasis, not typhoid.
2 A urine culture is used to confirm a urinary tract infection, not typhoid.
3 Serological antibodies can help diagnose typhoid.
4 A sputum test is used to detect Streptococcus pneumoniae, not typhoid.
Feedback
1 Ciliated respiratory tract cells do the physical act of sweeping away.
2 Alveolar macrophages are only present to phagocytose small organisms.
3 Respiratory epithelial cells secrete interferon, which is the body’s natural antiviral
cytokine.
4 Cervical lymph nodes store WBCs to defend against microorganisms.
Feedback
1 Pseudomonas aeruginosa can cause urinary tract infections in a hospital setting, and
urinary tract catheterization predisposes one to it.
2 Hospital food is not a source of pseudomonas infections, and it is not commonly
transmitted through oral routes.
3 Nebulizers cannot predispose clients to Pseudomonas aeruginosa.
4 Hospital linens are not a common cause of pseudomonas infection as skin contact is not
the method of transmission.
Feedback
1 There are no specific neurological tests to diagnose Legionnaire’s disease.
2 Tissue sampling is not used to diagnose Legionnaire’s disease.
3 Antibody titers have no role to play in diagnosing Legionnaire’s disease.
4 Arterial blood gases are used to diagnose Legionnaire’s disease.
Feedback
1 Pinpoint red macules and petechiae called Forchheimer spots are seen over the soft
palate and uvula in German measles.
2 Dewdrops on a rose petal is the classic pattern of rash of chickenpox.
3 A slapped-cheek appearance that looks like sunburn on the facial skin is the first stage
rash of Fifth disease.
4 Purpura and ecchymotic rash are seen in Neisseria meningitidis.
Feedback
1 Microcephaly is caused by cytomegalovirus.
2 Retinitis is caused by cytomegalovirus.
3 Toxoplasmagondii causes vision impairment in the fetus.
4 Since rubella affects the embryo by causing spontaneous abortion, it is said to have
teratogenic effects.
Feedback
1 Anemia is common to several medical conditions and not specific to malaria.
2 Bilirubin, which is a byproduct of hemoglobin breakdown, is common to other medical
conditions and therefore elevated bilirubin is not considered diagnostic for malaria.
3 Serological testing to diagnose specific antibodies against plasmodium is also diagnostic
for malaria.
4 A urine test will not help to diagnose malaria as it infects the blood and not the urinary
system.
Feedback
1 The African fruit bat is the reservoir for Marburg virus.
2 The white-tailed deer is the reservoir for Lyme disease.
3 Contaminated drinking water is a general reservoir for several infections but not
Neisseria meningitidis.
4 The human nasopharynx is the reservoir for Neisseria meningitidis.
Feedback
1 Prions are not bacterial spores.
2 Prions are abnormal proteins that are infectious.
3 Prions are not fungal in nature.
4 Helminths are worms, while prions are abnormal proteins.
Feedback
1 There are other pathogens that cause hemorrhagic fevers, and all of them are not
reportable or classified as Category A bioterrorism agents.
2 The potent killer combination and high infectivity make them Category A bioterrorism
agents.
3 There are several other pathogens that are transmitted through blood and body fluids
that are not classified as Category A bioterrorism agents.
4 There are several other diseases caused by pathogens that do not have standard
treatment options and they are not classified as Category A bioterrorism agents.
Feedback
1 While there is mental confusion in the variant, there is memory loss in
Creutzfeldt-Jakob disease, and therefore it is difficult to distinguish one from the other.
2 While there are personality changes in Creutzfeldt-Jakob disease, there are psychiatric
problems in the variant, making it difficult to distinguish one from the other.
3 There are problems with hearing, seeing, and smelling in variant Creutzfeldt-Jakob
disease and these symptoms are noted for weeks or months.
4 Involuntary jerky movements found in Creutzfeldt-Jakob disease are similar to poor
muscle coordination and muscle spasms found in variant Creutzfeldt-Jakob disease,
making it difficult to distinguish one from other.
Feedback
1 A blood test will not confirm a tapeworm infection.
2 A stool test can confirm the diagnosis of tapeworm by showing the presence of eggs or
segments of the worm.
3 A urine test cannot confirm a tapeworm infection.
4 Antibody titers are used for infections caused by microbes and not by tapeworm.
Feedback
1 Coccidiomycosis is a fungal infection caused by inhalation of fungal spores in the air.
2 There is no vector involved in the spread of coccidiomycosis. Vector-borne diseases can
be contagious, while coccidiomycosis is not.
3 While it is true that little is known about how prions (abnormal proteins) are formed or
gain entry into humans, it is not the cause of coccidiomycosis.
4 The fungal spores are inhaled from air and do not have an oral entry via contaminated
food.
Feedback
1 Women who contract vaginal candidiasis are not necessarily immunosuppressed and are
not prey to opportunistic infection.
2 Antibiotics destroy lactobacillus that actually keeps the vaginal pH low. This factor is a
protective mechanism to ward off infection.
3 Antibiotic-resistant bacteria do not cause vaginal candidiasis.
4 Antibiotics do not cause a decrease in vaginal pH, and if anything a decreased vaginal

Integrated Process: Nursing Process
Client Need: Safety and Effective Care Environment: Management of Care
Cognitive Level: Evaluation [Evaluating]
Concept: Critical Thinking
Feedback
1. This is correct. A prolonged manifestation could mean an immunocompromised state when
treatment becomes necessary.
2. This is incorrect. Absence of preventive vaccines is not a criterion for medical therapy.
3. This is correct. If the infection is a killer disease and easily transmitted, it is treated to
avoid risk to people in contact with the client.
4. This is correct. If certain stages of infection can cause undue risk to the client, the infection
has to be aborted before the stage is reached.
5. This is incorrect. When the first line of defense fails to contain an infection, the second line
of defense, called adaptive immune system, can contain the infection.
Feedback
1. This is correct. A culture of the infected tissue or body fluid is grown on agar to identify
the microbes.
2. This is correct. The extent of infection can be inferred by the number of microorganisms
per high-power field or volume of substrate.
3. This is incorrect. Antibodies to the antigen (microbes) are inferred from serological testing
as the blood and not the substrate will contain the antibodies.
4. This is correct. The culture medium can be infused with antibiotics to study the growth or
suppression of microbes.
Feedback
1. This is correct. Antibodies are found in blood serum and therefore are specific to
serological testing.
2. This is incorrect. Histology deals with the study of characteristic cell changes.
3. This is correct. Levels of IgM and IgG in the blood serum can predict the stage of
infection.
4. This is incorrect. Antigen identification combines culture and microscopic methods.
5. This is incorrect. Detection of a microorganism’s genetic material is achieved through
polymerase chain reaction (PCR).
Feedback
1. This is correct. The infection was present in the population but had not been detected.
2. This is correct. After a decline in the incidence of an infection, the infection can reoccur.
3. This is incorrect. Antibiotic-resistant bacteria cause reemergence of an infectious disease
and not emergence of an infectious disease.
4. This is incorrect. A breakdown in public health measures causes reemergence of infectious
disease.
5. This is correct. On realizing an established disease has an infectious origin, the disease
becomes an emerging infectious disease.

Cognitive Level:Application [Applying]
Concept: Infection
Feedback:The incubation period is the first stage when the pathogen begins to replicate in the host and has not
yet caused identifiable symptoms. The prodromal stage is the second stage when the host has a vague sense of
illness with an initial appearance of symptoms. The host is highly contagious in this stage. The acute stage is
the third stage when the symptoms become specific and the host experiences the full disease. The host’s
defenses are in full force fighting off the infection. The host remains contagious at this stage. The fourth stage
is the convalescent stage when the pathogen is gradually being eliminated and the infection is being contained
with a resolution of the symptoms. The resolution phase is the fifth and final phase with total elimination of
pathogens from the host and no residual signs or symptoms of the infection.
