Quiz Preview

  • 2. 

    A drug's _____ is the amount of time it takes for 50% of the blood concentration of a drug to be eliminated from the body.

    • Loading dose

    • Maintenance dose

    • Peak level

    • Therapeutic range

    • Half-life

    Correct Answer
    A. Half-life
    Explanation
    A drug's half-life is the amount of time it takes for 50% of the blood concentration of a drug to be eliminated from the body (p. 773)

    Rate this question:

  • 3. 

    True or False:In regards to the blood flow relating to pharmocokinetics, patients with imparied ciculatory function absorbe drugs more readily than patients with normal circulatory systems, because the slowly moving blood allows more time for medication to enter the blood.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Absorption is increased with increased blood flow. Patients with impaired ciculatory function aborb drugs LESS RAPIDLY than do patients with normal ciculatory function (p. 772).

    Rate this question:

  • 4. 

    The therapeutic range of a drug

    • Is tested by drawing blood and measuring the level of the drug in the plasma

    • Is the highest plasma concentration

    • Should be measured when absorption is complete

    • Is the amount of time it takes for 50% of the blood concentration of a drug to be eliminated from the body

    • Is the concentration of drug in the blood serum that produces the dired effect without causing toxicity

    Correct Answer
    A. Is the concentration of drug in the blood serum that produces the dired effect without causing toxicity
    Explanation
    A drug's therapeutic range is the concentration of drug in the blood serum that produces the desired effect without causing toxicity (p. 773)

    Rate this question:

  • 5. 

    True or False:Food will always expedite the absorption of medications.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Food in the stomach can delay the absorption of some medications or enhace the rate of absorption of other drugs (p. 773)

    Rate this question:

  • 6. 

    The highest plasma concentration of the drug, which should be measured when absorption is complete, is known as

    • Therapeutic range

    • Serum level

    • Peak level

    • Trough level

    • None of the above

    Correct Answer
    A. Peak level
    Explanation
    The highest plasma concentration of a drug, which is measured when absorption is complete, is known as the peak level. This measurement is important as it helps determine the maximum concentration of the drug in the body, which can be useful in determining the drug's efficacy and potential side effects. Monitoring the peak level allows healthcare professionals to adjust the dosage or frequency of administration if necessary to ensure optimal therapeutic effects.

    • All of the above

    Correct Answer
    A. It is the process of removing a drug, or its metabolites (products of metabolism), from the body
    Explanation
    The KIDNEYS excrete most drugs. The LUNGS are the primary route for the excretion of gaseous substances. Many drugs are excreted through BILE in the gastrointestinal tract. Manufacturers are REQUIRED BY LAW to include information regarding implications for geriatric patients on the package inserts of certain drugs (e.g. psychotropic drugs, nonsteroidal anti-inflammatory agents, oral hypoglycemic agents, anticoagulants, certain broad-spectrum antibiotics, and cardiac drugs) (p. 773).

    Toxic effects (toxicities) are specific groups of symptoms related to drug therapy and carry a risk for permaent damage or death. They are named after the organ or body system affected by tocixity (e.g. hepatotoxicity is damage to the liveR). A cummulative effect occurs when the body cannot metabolize one dose of a drug before another dose is administered. The drug is taken in more frequently that it is excreted, and each new dose increases the total quantity in the body (p. 774)
