質問 1：
During a community outbreak of influenza, a public health laboratory performs rapid antigen testing on nasopharyngeal swabs. A test for influenza A is positive, but the influenza B test is negative. Subsequently, RT-PCR is performed on the same sample, and it is negative for both influenza A and B viral RNA. The MOST likely explanation for this discordant result is:
A. The rapid antigen test yielded a false positive result, and the RT-PCR was a true negative.
B. The patient was infected with a novel influenza strain not detected by either assay.
C. The rapid antigen test has low sensitivity, resulting in a false positive.
D. The RT-PCR assay has a high limit of detection, missing a low viral load.
正解：A
質問 2：
Which of the following viruses is an enveloped, double-stranded DNA virus known to cause latent infections often reactivated during immunosuppression?
A. Poliovirus
B. Rotavirus
C. Influenza A virus
D. Cytomegalovirus (CMV)
正解：D
質問 3：
A patient with a history of valvular heart disease undergoes a dental procedure and subsequently develops a bloodstream infection with Streptococcus mutans. This organism gains access to the bloodstream primarily due to:
A. Production of potent extracellular enzymes.
B. Transient bacteremia resulting from the procedure.
C. Formation of a protective biofilm on the teeth.
D. Active invasion of the oral mucosa.
正解：B
質問 4：
A laboratory worker sustains a needlestick injury while handling a blood sample known to be positive for Hepatitis B surface antigen (HBsAg) and Hepatitis B e antigen (HBeAg). The worker has completed the HBV vaccination series and has a documented anti-HBs titer >10 mIU/mL one month ago. What is the recommended post-exposure prophylaxis?
A. Hepatitis B vaccine booster dose only
B. No treatment required
C. Both HBIG and HBV vaccine booster dose
D. Hepatitis B immune globulin (HBIG) only
正解：B
質問 5：
A clinical microbiology laboratory is implementing a new multiplex nucleic acid amplification test (NAAT) for the detection of respiratory viral pathogens. To ensure the quantitative accuracy of the assay, it is essential to include:
A. Only positive and negative controls.
B. External quality assessment samples.
C. Internal controls to monitor for PCR inhibition.
D. Calibration standards with known concentrations of target nucleic acids.
正解：D
質問 6：
A patient with a history of liver transplantation develops a bloodstream infection with a Gram-negative bacterium. The isolate is identified as Sphingomonas paucimobilis. This opportunistic pathogen is known for its ability to:
A. Exhibit intrinsic resistance to a broad spectrum of antibiotics.
B. Degrade a wide range of environmental pollutants.
C. Produce potent exotoxins that directly damage host tissues.
D. Form biofilms on indwelling catheters and prosthetic devices.
正解：A
