    • Disolusi

    • Distribusi

    • Metabolisme

    • Absorbsi

    Correct Answer
    A. Disolusi
    Explanation
    Disolusi adalah proses di mana obat larut dalam cairan tubuh sehingga dapat diabsorbsi oleh tubuh. Fase farmakokinetika mencakup empat tahap yaitu absorpsi (penyerapan obat ke dalam tubuh), distribusi (penyebaran obat ke dalam berbagai jaringan tubuh), metabolisme (pengubahan obat oleh enzim tubuh), dan eliminasi (pengeluaran obat dari tubuh). Oleh karena itu, disolusi termasuk dalam fase farmakokinetika dan bukan merupakan pengecualian.

    Alat yang digunakan untuk mengukur absorban sampel adalah..

    • Spektrofotometer UV-Vis

    • Sentrifuge

    • Vial

    • Tabung Eppendrof

    Correct Answer
    A. Spektrofotometer UV-Vis
    Explanation
    A spektrofotometer UV-Vis is used to measure the absorbance of a sample. This instrument is specifically designed to measure the amount of light absorbed by a sample at different wavelengths in the ultraviolet-visible (UV-Vis) range. By measuring the absorbance, the concentration of the sample can be determined, allowing for analysis of various substances such as chemicals, proteins, and nucleic acids. The other options, such as a centrifuge, vial, and Eppendorf tube, are not suitable for measuring absorbance and are used for other purposes in laboratory settings.

  • 8. 

    Alat yang digunakan untuk memisahkan plasma dan serum adalah..

    • Sentrifuge

    • Vial

    • Tabung Eppendorf

    • Spektrofotometer

    Correct Answer
    A. Sentrifuge
    Explanation
    A centrifuge is a device used to separate plasma and serum from blood samples. It works by spinning the sample at high speeds, causing the heavier components, such as blood cells, to settle at the bottom while the lighter components, such as plasma and serum, rise to the top. This separation is important in various medical and research applications, as plasma and serum contain different components that can provide valuable information about a person's health or be used in further analysis. Therefore, a centrifuge is the correct tool for this purpose.

    • Konsentrasi

    • Slope

    • Intercept

    • Eliminasi

    Correct Answer
    A. Konsentrasi
    Explanation
    The correct answer is "Konsentrasi". Pada kurva baku, nilai absorban yang terbaca pada spektrofotometer mencerminkan nilai konsentrasi obat dalam darah. Absorban adalah ukuran sejauh mana cahaya diserap oleh suatu zat, dan dalam konteks ini, absorban yang terbaca pada spektrofotometer akan berhubungan dengan konsentrasi obat dalam darah. Semakin tinggi konsentrasi obat, semakin tinggi pula nilai absorban yang terbaca pada spektrofotometer.

    Bagian dari darah yang akan diukur absorbannya adalah..

    • Serum

    • Plasma

    • Eritrosit

    • Hemoglobn

    Correct Answer
    A. Serum
    Explanation
    Serum is the correct answer because it refers to the fluid component of blood that remains after the blood has clotted and the clot has been removed. It does not contain any cells or clotting factors, making it suitable for measuring the absorbance of certain substances in the blood. Plasma, on the other hand, is the liquid component of blood that contains clotting factors and other proteins. Erythrocytes (red blood cells) and hemoglobin are cellular components of blood and are not directly measured for absorbance.
