Ujian Remedial Farmakokinetik 2015

The correct answer is "Cp maks". Cp maks is the symbol used to represent the highest drug concentration in the blood. This term is commonly used in pharmacokinetics to describe the peak concentration of a drug in the bloodstream after administration. It is an important parameter in determining the efficacy and safety of a drug, as it indicates the maximum therapeutic effect and the potential for adverse reactions.

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.

The correct answer is t 1/2. This refers to the time it takes for a drug to decrease by half its initial concentration. It is commonly used to measure the rate at which a drug is eliminated from the body.

The correct answer is AUC, which stands for Area Under the Curve. This term is commonly used in mathematics and statistics to measure the area between a curve and the x-axis. In the context of the given question, it is likely referring to the area under a specific curve, possibly in a graph or a mathematical function.

The correct answer is Ka. In pharmacokinetics, Ka represents the absorption rate constant, which is a measure of how quickly a drug is absorbed into the bloodstream. It is used to describe the rate at which a drug moves from the site of administration (such as the gastrointestinal tract) into the systemic circulation. Ka is an important parameter in drug absorption studies as it helps to determine the bioavailability and onset of action of a drug.

Volume distribusi adalah parameter farmakokinetika yang menggambarkan sejauh mana obat didistribusikan ke dalam jaringan tubuh setelah diberikan. Ini menunjukkan seberapa luas obat tersebar di luar aliran darah dan dapat memberikan gambaran tentang distribusi obat ke berbagai organ dan jaringan. Semakin tinggi volume distribusi, semakin banyak obat yang terdistribusi ke jaringan tubuh dan semakin rendah konsentrasi obat dalam darah.

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.

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.

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.

The correct answer is "b" because slope is commonly represented by the letter "b" in mathematics and physics. It is a measure of how steep a line or surface is, indicating the rate of change between two points. The letter "b" is used as a standard symbol for slope in equations and formulas, making it the correct choice in this context.

Na CMC adalah pelarut obat yang akan diberikan pada hewan coba.

Jawaban yang benar adalah "Naik". Ketika slope (b) memiliki nilai positif, maka menunjukkan bahwa ada hubungan positif antara variabel independen dan variabel dependen. Dengan kata lain, ketika nilai variabel independen meningkat, nilai variabel dependen juga cenderung meningkat. Oleh karena itu, kecenderungan data adalah naik.

The correct answer is "a". This is because the intercept on the y-axis represents the point where the graph intersects the y-axis. In this context, "a" is the symbol commonly used to represent the y-intercept.

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.

In the laboratory practice "Pharmacokinetic Parameters of Intravenous Drugs", the correct place to collect blood from a rabbit is the ear. This is because the ear veins in rabbits are easily accessible and have a large enough diameter to allow for easy blood collection. Additionally, the ear is a relatively safe and less invasive site compared to other options such as the tail or abdomen.

The correct answer is 10 menit. This suggests that it takes 10 minutes to separate plasma and serum using a centrifuge.

The correct answer is "Vena". The given statement mentions that small blood vessels in a test animal are used for blood collection. Vena refers to veins, which are blood vessels that carry deoxygenated blood back to the heart. Veins are commonly used for blood collection as they are easily accessible and have lower pressure compared to arteries. Therefore, vena is the most suitable answer in this context.

The correct answer is 10.000 rpm because a high centrifuge speed is required in the laboratory practice. Centrifuges are used to separate components of a mixture based on their density by applying centrifugal force. Higher speeds allow for faster and more efficient separation of the components. Therefore, 10.000 rpm is the most suitable speed for this practical application.

The correct answer is 250 g. This suggests that the weight of the mouse used for the practical is 250 grams.

The correct answer is "Distribusi dan eliminasi". Disposisi obat refers to the description of the pharmacokinetic phase, which involves the distribution and elimination of the drug. This means that after absorption, the drug is distributed throughout the body and eventually eliminated from the body through various processes.
