   4.   All of the above
2. Dose is defined as,
   
   1.   Amount of drug taken to produce intended medical response.
   2.   Amount of drug causing poisoning
   3.   Amount of dosage forms available for drugs
   4.   None of the above
3. Pediatric doses are lesser than normal doses because,
   1.   Of their lower body size.
   2.   Of their lesser body weight
   3.   Their immunity system is not well developed
   4.   Immature state of their hepatic and renal function by which drugs are inactivated and eliminated from the body
4. Geriatric doses are lesser than normal doses because,
   1.   Of their body size.
   2.   Of their body weight.
   3.   Their immunity system is not working well
   4.   Slow drug clearance and increases the possibility of drug accumulation in the body and subsequent toxicity
5. Drug dosage may require adjustment from the usual adult dose for abnormally lean or obese patients because,
   1.   Normal doses are considered suitable for 70 kg (150 pounds) individuals.
   2.   The ratio between the amount of drug administered and the size of the body influences the drug concentration at the site of action.
   3.   Both a & b are right statements
   4.   Both a & b are wrong statements.
6. Drugs have to be given cautiously to females in…..
   1.   Pregnancy
   2.   Lactation
   3.   Menstruation
   4.   All of the above
7. Females usually require a lesser dose as compared to males.
   1.   True
   2.   False
8. The policy to avoid tolerance development is,
   
   1.   Initiating therapy with the lowest effective dose
   2.   Avoiding prolonged administration
   3.   Only “a”
   4.   Both a & b.
9. Some drugs are advised before meals to,
   1.   Avoid dose dumping.
   2.   Avoid interaction with food.
   3.   Improve absorption.
   4.   Both B & C.
10. Some drugs are advised after meals to,
    1.   Improve absorption.
    2.   Better tolerance.
    3.   Only “B”.
    4.   Both A & B.
11. Drug interactions may be “Beneficial”.
    1.   True.
    2.   False.
12. Drug interactions are always “Detrimental”.
    1.   True.
    2.   False.
13. Sedatives dose is required more in day time than in night.
    1.   True: Darkness increases activity of sedatives.
    2.   False: Sunlight increases activity of sedatives.
    3.   True: Because sedatives show better absorption at night.
    4.   False: Because sedatives only show increased absorption in day time.
14. Placebos contain,
    1.   No active medicine but has similar appearance as the original dosage form.
    2.   More active medicine than original dosage form.
    3.   Medicines that are cheaper than original drugs.
    4.   All of the above.
15. A lesser dose is required if the drug is given by,
    1.   Oral route.
    2.   Topical route.
    3.   Intravenous route.
    4.   None of the above.
16. Reduction in particle size increases absorption because it,
    1.   Reduces interaction with food molecules.
    2.   Increases interaction with food molecules.
    3.   Reduces effective surface area.
    4.   ncreases effective surface area.
17. The schedule of dosing ( four times a day, two times a day etc.) is called,
    1.   Dose inspection.
    2.   Dose regimen.
    3.   Dose calibration.
    4.   All of the above.
18. Doses of childrens are calculated by Young’s formula, which formula is right.
    1.   Adult Dose (mg/day) x [Age / (Age+12)]
    2.   Adult Dose (gm/day) x [Age / (Age+24)]
    3.   Adult Dose (mg/day) x [Wt in Kg / (Age+12)]
    4.   Adult Dose (mg/day) x [Wt in Kg / (Age+24)]
19. Clark’s formula to calculate pediatric dose uses body wt in pounds, which of the following formula is correct representation,
    1.   Adult Dose (gm/day) x (Child Weight in Lbs /150)
    2.   Adult Dose (mg/day) x (Child Weight in Lbs /150)
    3.   Adult Dose (mg/day) x (Child Weight in Lbs /250)
    4.   Adult Dose (gm/day) x (Child Weight in Lbs /250)
20. Pediatric dose can be calculated by considering child’s,
    1.   Age.
    2.   Body Weight.
    3.   Body Surface area
    4.   All of the above.
