  • 2. 

    Specimens for the microbiology lab should be processed

    • As soon as possible because the length of incubation time does have a bearing on microbiology culture results

    • As a batch because it saves time and the length of incubation time has no bearing on microbiology culture results

    • Have the lowest priority when working on the evening/nite shifts in the laboratory

    • Only by the microbiology department technologists

    Correct Answer
    A. As soon as possible because the length of incubation time does have a bearing on microbiology culture results
    Explanation
    Specimens for the microbiology lab should be processed as soon as possible because the length of incubation time does have a bearing on microbiology culture results. This means that the longer the specimens are left without being processed, the more time bacteria or other microorganisms have to grow and potentially affect the results of the culture. Processing the specimens quickly helps ensure accurate and reliable results.

  • 3. 

    Specimens that are collected in viral transport can be processed for routine bacterial culture and sensitivity testing?

    • TRUE

    • FALSE

    Correct Answer
    A. FALSE
    Explanation
    Specimens that are collected in viral transport media are specifically designed to preserve and transport viruses, not bacteria. Therefore, these specimens cannot be used for routine bacterial culture and sensitivity testing.

    MRSA's are ________________________________ resistant.

    Correct Answer
    Oxacillin
    Explanation
    MRSA's are resistant to Oxacillin.

    This is a gram stain typical of what organism classifcation? - ProProfs

    This is a gram stain typical of what organism classifcation?

    • Pseuodmonas species

    • Staphylococci

    • Streptococci

    • Diptheroids

    Correct Answer
    A. Diptheroids
    Explanation
    Diptheroids are a type of bacteria that are commonly found on the skin and mucous membranes of humans. They are gram-positive bacteria, meaning they retain the crystal violet stain during the gram staining process. This distinguishes them from gram-negative bacteria like Pseudomonas species. Staphylococci and Streptococci are also gram-positive bacteria, but they have distinct characteristics that differentiate them from diptheroids. Therefore, based on the gram stain, the given bacteria are most likely diptheroids.

    A strep culture has been ordered on a throat swab. What pathogenic organisms should be reported?

    • Group A strep that is PYR positive and Latex Grp A positive

    • Group A strep that is PYR negative but latex Grp A positive

    • Group B strep

    • Group F strep

    Correct Answer
    A. Group A strep that is PYR positive and Latex Grp A positive
    Explanation
    The correct answer is "Group A strep that is PYR positive and Latex Grp A positive." This is because a strep culture is specifically ordered to identify Group A streptococcus, which is known to cause various infections such as strep throat. The presence of PYR positivity and positive latex test for Group A strep confirms the identification of this pathogenic organism. Group B strep and Group F strep are not relevant in this context as they are not the target organisms for the strep culture.

    A specimen collected from the Emergency Department for RSV, INFLUENZA A/B, AND RESPIRATORY VIRAL PROFILE needs to be sent down in three separate viral transport media containers.

    • FALSE

    • TRUE

    Correct Answer
    A. FALSE
    Explanation
    ONLY ONE VIRAL TRANSPORT SPECIMEN CONTAINER IS NECESSARY FOR PROCESSING ALL THREE TESTS. KEEPING IN MIND THAT THE SPECIMEN NEEDS TO BE SAVED IN THE MICRO LAB SO THAT IT CAN BE SENT OUT TO IU/CLARIAN FOR THE RESPIRATORY VIRAL PROFILE BY THE MICROBIOLOGY DEPARTMENT THE FOLLOWING SHIFT.

  • 8. 

    The D - test quality control needs to be set up:

    • Monthly

    • Weekly

    • On each day of patient use

    • Daily

    Correct Answer
    A. On each day of patient use
    Explanation
    The D - test quality control needs to be set up on each day of patient use to ensure the accuracy and reliability of the test results. Setting up the quality control on a daily basis allows for regular monitoring and detection of any potential issues or errors that may arise during the testing process. This ensures that the test results are consistently accurate and reliable, providing healthcare professionals with reliable information for patient diagnosis and treatment.

  • 9. 

    What drug was developed to "beat out" the resistance to penicillins?

    Correct Answer
    Oxacillin
    Explanation
    Oxacillin was developed to overcome the resistance to penicillins. It is a type of penicillinase-resistant penicillin, meaning it is not easily broken down by the enzyme penicillinase that some bacteria produce to resist the effects of penicillins. By modifying the structure of the penicillin molecule, oxacillin was able to evade the action of penicillinase and effectively treat infections caused by penicillin-resistant bacteria.

  • 10. 

    The organism Staphlyococcus saprophyticus is

    • Coagulase negative

    • Novobiocin resistant

    • Beta-hemolytic

    • A pathogen of concern for women of childbearing age

    Correct Answer(s)
    A. Coagulase negative
    A. Novobiocin resistant
    A. A pathogen of concern for women of childbearing age
    Explanation
    Staphylococcus saprophyticus is a coagulase-negative bacterium, meaning it does not produce the enzyme coagulase. It is also resistant to novobiocin, an antibiotic commonly used to treat staphylococcal infections. Additionally, it is considered a pathogen of concern for women of childbearing age, as it is a common cause of urinary tract infections in this population.

    What 2 comments need to be added to a urine culture report that has >100,000 CFU/mL Enterococci species that is positive on the Vancomycin Screen and has been confirmed by the Microscan as Enterococcus faecium?

    Correct Answer(s)
    Vancomycin Resistant Enterococci isolated and ENTEROCOCCUS ARE SCREENED FOR VANCOMYCIN RESISTANCE FOR EPIDEMIOLOGICAL PURPOSES. AMPICILLIN IS THE DRUG OF CHOICE FOR TREATING ENTEROCOCCAL INFECTIONS RESTRICTED TO THE URINARY TRACT.
    MVRE
    Explanation
    The two comments that need to be added to the urine culture report are: "Vancomycin Resistant Enterococci isolated and ENTEROCOCCUS ARE SCREENED FOR VANCOMYCIN RESISTANCE FOR EPIDEMIOLOGICAL PURPOSES" and "AMPICILLIN IS THE DRUG OF CHOICE FOR TREATING ENTEROCOCCAL INFECTIONS RESTRICTED TO THE URINARY TRACT." The first comment indicates that the Enterococci species isolated from the urine culture are resistant to vancomycin, which is important information for treatment decisions and infection control measures. The second comment provides guidance on the appropriate drug choice for treating Enterococcal infections that are limited to the urinary tract.

    Rate this question:

  • 12. 

    Which of the following types of gram stains needs to be performed on all shifts?

    • CSF

    • Positive Blood Culture

    • STAT! Body Fluid

    • STAT! gram stain on OR/Surgical specimen

    Explanation
    The correct answer is STAT! gram stain on OR/Surgical specimen. This type of gram stain needs to be performed on all shifts because it is time-sensitive and the results are needed urgently in order to guide immediate patient care decisions during surgery or other invasive procedures.

    The gram positive organsms shown here are more than likely what? - ProProfs

    The gram positive organsms shown here are more than likely what?

    • Diptheroids

    • E.coli

    • Staphlyococci

    • Neisseria species

    Explanation
    The gram positive organisms shown here are more than likely Staphylococci. This can be inferred from their characteristic appearance under Gram staining, where they appear as clusters of spherical cells. Staphylococci are commonly found on the skin and mucous membranes of humans and animals, and they are known to cause a variety of infections, including skin infections, pneumonia, and bloodstream infections.

    Rate this question:

  • 14. 

    Can you tell me "how" MRSA's are penicillin resistant and what the drug of choice is for MRSA infections?
