Question 1 of 5
How soon after a potentially infectious bite should a person be treated for rabies?
Correct Answer: B
Rationale: The correct answer is B: Within 24 hours. Rabies post-exposure prophylaxis should ideally be initiated as soon as possible after a potentially infectious bite to prevent the virus from spreading and causing symptoms. Immediate treatment is crucial to prevent the virus from reaching the central nervous system. Waiting beyond 24 hours increases the risk of the virus reaching the brain and becoming fatal. Choices A, C, and D are incorrect because waiting for 6 months, a week, or 2 weeks respectively would significantly delay treatment, allowing the virus to progress and potentially become untreatable.
Question 2 of 5
Which of the following organisms is the causative agent of skin infections and toxic shock syndrome?
Correct Answer: B
Rationale: The correct answer is B: Staphylococcus aureus. This bacteria is known to cause skin infections and toxic shock syndrome due to its ability to produce toxins that can lead to severe symptoms. Staphylococcus aureus is commonly found on the skin and can enter the body through cuts or wounds, causing infections. Other choices are incorrect because Pseudomonas aeruginosa typically causes infections in immunocompromised individuals, Micrococcus luteus is a common skin bacterium that is not typically pathogenic, and Propionibacterium acnes is associated with acne, not skin infections or toxic shock syndrome.
Question 3 of 5
What is soor?
Correct Answer: D
Rationale: The correct answer is D: Oral candidiasis. Soor is a term used to describe oral candidiasis, a fungal infection caused by Candida species. This infection presents as white patches on the tongue, inner cheeks, and roof of the mouth. The other choices (A, B, C) refer to different types of fungal infections affecting various parts of the body, not specifically the oral cavity. Therefore, based on the description of soor and its characteristics, the correct answer is D.
Question 4 of 5
Which bacteria are capable of forming spores to survive extreme conditions?
Correct Answer: C
Rationale: Rationale: 1. Both Clostridium botulinum and Bacillus anthracis are known to form spores. 2. Spore formation is a mechanism for survival in harsh conditions. 3. Both bacteria are capable of causing severe diseases in humans. Summary: - Choice A and B are incorrect because each bacteria listed is capable of spore formation. - Choice D is incorrect as both bacteria mentioned can form spores to survive extreme conditions.
Question 5 of 5
A married couple applied to the genetic consultation in order to consult about their child with multiple abnormalities (microcephaly, idiocy etc). The woman has had an illnesses during her pregnancy but she didn't take any teratogens or mutagens. The parents' and the child's karyotype is normal. Anamnesis study revealed that the family kept a cat. What gravidic disease caused the child's abnormalities?
Correct Answer: A
Rationale: The correct answer is A: Toxoplasmosis. Toxoplasmosis is a parasitic infection caused by Toxoplasma gondii, which can be transmitted to humans through contact with infected cat feces. During pregnancy, Toxoplasma infection can result in severe birth defects such as microcephaly and mental retardation in the child. In this case, the presence of a cat in the family and the child's abnormalities suggest a possible link to Toxoplasmosis. Other choices are incorrect because: B: Leishmaniasis is a parasitic disease transmitted by sandflies and does not typically cause the specific birth defects mentioned in the scenario. C: Dysentery is a bacterial infection that primarily affects the intestines and does not cause the neurological abnormalities described. D: Balantidiasis is a parasitic infection caused by Balantidium coli, a ciliated protozoan, but it is not associated with
