Total questions: 10
Worksheet time: 5mins
Which diagnostic method provides information about the viability and antibiotic susceptibility of microorganisms?
Serology
Classical microbiological culture
PCR
When is it most appropriate to collect blood cultures?
At the peak of fever
After finishing antibiotic therapy
Always in the morning, fasting
What is a major limitation of serological diagnostics in infectious diseases?
It is too rapid
It may be unreliable in immunocompromised patients
It does not require blood samples
Which molecular technique is most commonly used to detect pathogen genetic material?
Immunofluorescence
PCR
Light microscopy
How can false-positive results in cultures of biological material be avoided?
Collecting samples under sterile conditions
Extending the transport time to the lab
Mixing samples from different patients
In which situations are rapid antigen tests particularly useful?
In infections requiring immediate therapeutic decisions
In chronic, asymptomatic infections
In epidemiological studies with high sensitivity
Why is culture important in the treatment of bacterial infections?
It allows determination of antimicrobial resistance
The result is immediate
It detects viral infections
Which test is most appropriate for diagnosing acute viral infections (e.g., influenza)?
PCR
Bacterial culture
Detection of IgG antibodies
What is the main advantage of multiplex PCR panels in diagnostics?
They can simultaneously detect multiple pathogens in a single sample
They are always cheaper than culture
They provide results only after several days
Which factor most often determines the choice of diagnostic method in clinical practice?
Cost and time to results
Patient preference
The color of bacterial colonies
