During which part of the EKG does the depolarization of the ventricular anterior aspect and septum occur? Select one: a. T wave b. Q wave c. R wave d. S wave e. P wave During the plateau of the ventricular muscle action potential, the membrane potential remains basically unchanged. The movements of which two ions are mainly responsible? Select one: a. Sodium influx, calcium efflux b. Potassium influx, calcium efflux c. Potassium efflux, calcium efflux d. Potassium efflux, calcium influx e. Potassium influx, calcium influx f. Potassium influx, sodium efflux g. Sodium influx, potassium efflux Solution Ques-1 Answer: b. Q wave Reason: QRS complex is also known as initial ventricular complex, which is produced due to the ventricular depolarization. Q wave is a negative wave that continues as a positive R wave (tallest wave). R wave is followed by S wave, which is a negative wave. The EKG with Q wave does the depolarization of the ventricular anterior aspect and septum occur because it is generated via downward deflection after P wave. In case lead V1, depolarization meticulously associated with the ventricular anterior aspect and septum & it is not abnormal if it is missing from any particular lead, it is significant if its higher than 1 mm wide. It also considered as abnormal if it is 25% - 33% of total amplitude of the R wave..

1. E1-1 Reporting Amounts on the Four Basic Financial Statements [LO 1-2) Using the following
table and the eqtations underlying each of the four basic financial statements, show (a) that the
balance sheet is in balance, (b) that net income is properly calculated, (c) what caused changes in
the retained earnings account, and (d) what caused changes in the cash account. (Cash outflows
should be indicated with a minus sign.) $19,900 14,600 . Assets Stockholders' Equity 5,300
12,200 10,050 2,150 Net Income Dividends Beginning Retained Earnings Ending Retained
Eamings Cash Flows from Operating Activities Cash Flows from Investing Activities Cash
Flows from Financing Activities Beginning Cash Ending Cash 5,200 6,500 3,300 (2,700) (1,750)
2,700 1,550 b. d.
Solution
a Assets = Liabilities+Stockholder's equity =14600+5300 Assets
reported = 19900 b Net income = Revenue-Expenses
=12200-10050 Net income reported = 2150 c Ending
Retained earnings = Beginning Retained Earnings+Net income-Dividends =5200+2150-
850 = 6500 d Ending Cash = Beginning Cash+Cash Flows from
Operating Activities+Cash Flows from Investing Activities+Cash Flows from Financing
Activities =2700+3300+(2700)+(1750)=1550
