Question 1

You advise your pregnant friend to not adopt a new kitten from her neighbor because she could contract

Accepted Answer

Toxoplasmosis is a parasitic infection that can be transmitted through contact with infected cat feces, which can pose a risk to pregnant women and their unborn babies.

Question 2

Epstein-Barr virus has been implicated in all of the following EXCEPT

Accepted Answer

Epstein-Barr virus has been implicated in infectious mononucleosis, nasopharyngeal carcinoma, Burkittʹs lymphoma, and Hodgkinʹs disease, but not endocarditis.

Question 3

Which of the following is the same for both relapsing fever and undulant fever?

Accepted Answer

Both relapsing fever and undulant fever are characterized by rising and falling body temperature.

Question 4

Which of the following leads to all the others?

Accepted Answer

The answer of Which of the following leads to all...

Question 5

A patient complains of fever, severe muscle and joint pain, and a rash. The patient reports returning from a Caribbean vacation one week ago. Which of the following do you suspect?

Accepted Answer

The combination of fever, severe muscle and joint pain, and a rash in a patient with recent travel to the Caribbean suggests dengue, a viral infection transmitted by mosquitoes. The other options listed may also cause fever and rash, but do not typically cause severe muscle and joint pain.

Question 6

Which of the following is NOT a zoonosis?

Accepted Answer

Puerperal sepsis is an infection that occurs after childbirth and is not a zoonosis. The other options (brucellosis, Hantavirus infection, anthrax, and tularemia) are all zoonoses, which are infections that can be transmitted from animals to humans.

Question 7

Which of the following pairs regarding the epidemiology of malaria is mismatched?

Accepted Answer

Ixodes is not a vector for malaria. It is a vector for other diseases such as Lyme disease and tick-borne encephalitis. The correct vector for malaria is Anopheles mosquitoes.

Question 8

Which of the following pairs is mismatched?

Accepted Answer

Cat-scratch disease may cause a small bump or blister at the site of the scratch or bite, but it does not progress to a malignant pustule or septicemia.

Question 9

Which of the following pairs is NOT correctly matched for Gram reaction?

Accepted Answer

Ehrlichia is a gram-negative bacterium, not gram-positive.

Question 10

A characteristic symptom of plague is

Accepted Answer

Plague typically presents with swollen and tender lymph nodes, commonly referred to as buboes.

Question 11

Arthropods can serve as a reservoir for all of the following diseases EXCEPT

Accepted Answer

Arthropods are known to be reservoirs for many diseases, including yellow fever, plague, epidemic typhus, and malaria. However, brucellosis is not typically considered an arthropod-borne disease and is instead usually spread through contaminated food or direct contact with infected animals.

Question 12

A predisposing factor for infection by Clostridium perfringens is

Accepted Answer

The answer of A predisposing factor for infection by Clostridium...

Question 13

Which of the following pairs is mismatched?

Accepted Answer

The answer of Which of the following pairs is mismatched?
...

Question 14

A patient returning from an extended trip into Mexico has the following symptoms: a papule at the site of a previous bug bite and enlarged lymph nodes. Microscopic examination of the papule reveals nucleated cells in white blood cells. The patient most likely has

Accepted Answer

The presence of a papule at the site of a previous bug bite and enlarged lymph nodes suggest a parasitic infection. Leishmaniasis is caused by the protozoan Leishmania, which is transmitted to humans through the bites of infected sand flies. The presence of nucleated cells in white blood cells is also characteristic of Leishmaniasis. Schistosomiasis, brucellosis, and malaria do not typically present with a papule, and anthrax is caused by a bacterium, not a parasite.

Question 15

Which of the following can be transmitted from an infected mother to her fetus across the placenta?

Accepted Answer

Cytomegalovirus is a common viral infection that can be spread from an infected mother to her fetus across the placenta. The other options are bacterial infections that are not typically transmitted in this manner.

Question 16

Which of the following is NOT treated with antibiotics?

Accepted Answer

Ebola is caused by a virus and is not treated with antibiotics, but rather with supportive care to manage symptoms and prevent complications. The other options listed are bacterial infections that can be treated with antibiotics.

Question 17

Human-to-human transmission of plague is usually by

Accepted Answer

Human-to-human transmission of plague can occur through droplets in the air that are released by infected individuals when they cough or sneeze. This is known as the respiratory route of transmission.

Question 18

Which of the following CANNOT be transmitted to humans from domestic cats?

Accepted Answer

Chagas' disease is typically transmitted to humans through vectors such as kissing bugs, and while domestic cats can be infected with the parasite that causes this disease, they are not an important reservoir host and are unlikely to directly transmit the disease to humans. Bartonella, plague, and toxoplasmosis can all be transmitted from domestic cats to humans.

Question 19

Scrapings from a patientʹs rash reveal cercariae. The disease is most likely

Accepted Answer

The presence of cercariae in the rash scrapings suggests swimmer's itch, a parasitic infection caused by the larval stage of certain flatworms. Relapsing fever, Lyme disease, Rocky Mountain spotted fever, and Chagas' disease are not associated with cercariae.

Question 20

Which of the following produces a permanent carrier state following infection?

Accepted Answer

The answer of Which of the following produces a permanent...
