    Eosinophils are a type of white blood cell (WBC) that make up approximately 1-4% of the total WBC count.

    Rate this question:

  • 46. 

    Bands are what percent of total WBC

    • 20 - 40

    • 2 - 8

    • 0.5 - 1

    • 40 - 60

    • 0 - 3

    Correct Answer
    A. 0 - 3
    Explanation
    This answer represents the percentage range of bands (immature white blood cells) in the total white blood cell count. The range of 0-3% suggests that bands make up a very small percentage of the total white blood cells.

    Proteus mirabilis

    • Gram positive cocci

    • Gram negative cocci

    • Gram positive bacilli

    • Gram negative bacilli

    Correct Answer
    A. Gram negative bacilli
    Explanation
    The correct answer is "Gram negative bacilli" because Proteus mirabilis is a type of bacteria that is classified as Gram negative bacilli. Gram negative bacteria have a thin peptidoglycan layer in their cell walls, which causes them to retain the counterstain (usually red or pink) in the Gram staining process. Bacilli refers to the shape of the bacteria, which are rod-shaped. Therefore, Proteus mirabilis fits the description of being Gram negative bacilli.

    Effective against gram negative organisms

    • First Generation PCN

    • Antistaphycoccal PCN

    • Extended spectrum PCN

    Correct Answer
    A. Extended spectrum PCN
    Explanation
    Extended spectrum PCN is the correct answer because it is a type of penicillin that is effective against a broad range of gram-negative organisms. Unlike first generation PCN, which primarily targets gram-positive bacteria, and antistaphylococcal PCN, which specifically targets staphylococcal infections, extended spectrum PCN has a wider spectrum of activity and can be used to treat infections caused by both gram-positive and gram-negative bacteria.

    Have good anaerobic coverage

    • First generation PCN

    • Antistaphycoccal PCN

    • Extended spectrum PCN

    Correct Answer
    A. Extended spectrum PCN
    Explanation
    Extended spectrum PCN refers to penicillin antibiotics that have a broader spectrum of activity against various types of bacteria. These antibiotics are effective against both aerobic and anaerobic bacteria, providing good anaerobic coverage. This means that they can effectively treat infections caused by both types of bacteria, which is important as anaerobic bacteria can cause serious infections in certain parts of the body where oxygen is limited, such as the gastrointestinal tract or deep wounds. Therefore, having good anaerobic coverage is a desirable characteristic of extended spectrum PCN.
