ECO 403

QUESTION ː A

Gross Domestic Product (GDP) for year 2007.?

ANSWER

                        Formula

Y= C+I+G+NX  

=1700+100+700

                                                           =   2500

NX (means net export –import)

                                            (250-450)     =   -200

                                             = 2500-200

                                                    = 2300 ans.

QUESTION ː B

Net exports (NX) for year 2008?

ANSWERː

                                  Net exports =exports - imports

=450-750

= -300 ans.

QUESTION ːC

 Unemployment rate for the year 2007 and 2008?

ANSWERː

                                    Calculation for 20007

                                           number of unemployment / Total labor force *100

= 79000/700000

                                                                    =0.1129 ans.

                                           Calculation for 2008

                                    number of unemployment / Total labor force *100

= 49000/800000       

= 0.0613 ans.

QUESTION ː D

GDPdeflator for the year 2008 if realGDPand NominalGDPfor this year are RS.2500
million and Rs.2650 million respectively.?

ANSWERː

                                GDP deflator  = nominal GDP / Real GDP * 100

                                                =      2650/2500*100

                                                 = 106 . GDPDEFLATOR ans.

                                                                                                                     .

 is it correct???/?

Examples

1)  Prepare a 1% solution of Brevital (500 mg of powder in bottle).  How many mL of sterile water will you use?

Answer:  First convert 1% solution to mg/cc.  A 1% solution is the same as 1000 milligrams in 100 cc or 10mg/cc.

Percent solutions all are 1000mg/100cc.  For example a 2% = 20mg/cc, 5% = 50mg/cc, 5.5% = 55mg/cc, etc...

Now you have all the information needed to use the IV dosage calculator.  This problem is the same as the doctor ordering a 500 mg IV bag of Brevital:  500 mg = dose ordered, 10mg = dose available, and 1cc = mL available (the last two values come from 10mg/cc obtained above).  The answer is 50cc.

2)  1.4cc of ½% tetracaine (Pontocaine) was given in a subarachoid block.  How many mg were given?

Answer: First convert ½% to mg/cc.  A 0.5% solution is the same as 500mg/100cc (5mg/cc).

Now you have all the information needed to use the mL/hr to dose/hr calculator.  1.4 cc = mL given, 5mg = dose available, and 1cc = mL available.  So 7mg of tetracaine were given.

Epinephrine Solutions

Epinephrine vials are also labeled by concentration of a ratio of medication per mL.  For example, a solution may be labeled as 1:100,000.  This concentration represents 1000mg/100,000mL or 0.01mg/mL.  Here are some others:

CONCENTRATIONDOSAGE EQUIVALENCEPERCENT
1:1,0001mg/mL0.1%
1:10,0000.1mg/mL0.01%
1:100,0000.01mg/mL0.001%
1:200,0000.005mg/mL0.0005%

Example

How many mg of epinephrine are in 5cc of a 1:10,000 solution?

Answer:  First convert 1:10,000 into mg/cc.
1:10,000 = 1000mg/10,000cc = 0.1mg/cc

Next use the IV dose given calculator.  5cc = mL given, 0.1mg = dosage available, and 1cc = mL available.  The answer is 0.5 mg of epinephrine were given.
