A neonatal intensive care unit needs electrodes for continuous ECG monitoring of premature infants over several days. The electrodes must conform to the curved surfaces of tiny limbs and torso, remain comfortable, not require removal for X-rays, but the unit has a limited budget. Compare carbon-filled silicone rubber electrodes versus thin-film Mylar electrodes with Ag/AgCl deposition for this application.   Carbon-filled silicone is better because it has lower impedance than thin-film electrodes  Carbon-filled silicone is better because it provides better conformability to curved infant surfaces  Thin-film electrodes are better because they are X-ray transparent and don’t need removal, despite having higher impedance  Both are equally suitable since they’re both flexible electrode types

As an action potential propagates along a nerve axon, it creates electric dipoles. What is the configuration of charges in these dipoles, and how do they relate to measurable surface potentials?   The action potentials produced by excitable cells inside the body have no effect on surface measurements Equal distribution of charges that cancel out any measurable potentials Alternating positive and negative regions that only exist intracellularly Positive charges inside and negative charges outside at the active region; these dipoles generate current loops that create measurable potentials in the extracellular space

What is the output? #include void PrintWaterTemperatureForCoffee(int temp) {if (temp < 195) {printf("Too cold.");}else if ((temp >= 195) && (temp 205) {printf(“Too hot.”);}} int main(void) {PrintWaterTemperatureForCoffee(100);PrintWaterTemperatureForCoffee(300);return 0;}

What is the output if myContact.txt file does not exist?   #include int main(void) {FILE* inputFile = NULL;printf(“Opening the file.”);inputFile =fopen(“myContact.txt”, “r”);if (inputFile ==NULL) {printf(“Could not open the file. “);return 1;}fclose(inputFile);return 0;}     Hints: Opening Modes Description r Searches file. Opens the file for reading only. If the file is opened successfully fopen() loads it into memory and sets up a pointer that points to the first character in it. If the file cannot be opened fopen() returns NULL. w Searches file. If the file exists already, its contents are overwritten. If the file doesn’t exist, a new file is created. Returns NULL, if unable to open the file. It creates a new file for writing only(no reading). a Searches file. If the file is opened successfully fopen() loads it into memory and sets up a pointer that points to the last character in it. If the file doesn’t exist, a new file is created. Returns NULL, if unable to open the file. The file is opened only for appending(writing at the end of the file). r+ Searches file. Opens the file for both reading and writing. If opened successfully, fopen() loads it into memory and sets up a pointer that points to the first character in it. Returns NULL, if unable to open the file. w+ Searches file. If the file exists, its contents are overwritten. If the file doesn’t exist, a new file is created. Returns NULL, if unable to open the file. The difference between w and w+ is that we can also read the file created using w+. a+ Searches file. If the file is opened successfully fopen( ) loads it into memory and sets up a pointer that points to the last character in it. If the file doesn’t exist, a new file is created. Returns NULL, if unable to open the file. The file is opened for reading and appending(writing at the end of the file).  

What is the output? #include void CheckValue(int* pointVar1, int* pointVar2) {if (*pointVar2 < *pointVar1) {printf("%d\n", *pointVar2);}else if (*pointVar1 < *pointVar2) {printf("%d\n", *pointVar1);}} int main() {int num1 = 33;int num2 = 21;CheckValue(&num1, &num2);return 0;}  

What is the output? #include int MyFct(int x) {return x;int y;x = x * 2;y = x + 1;} int main(void) {int a;a = 5;printf(“%d %d”, a, MyFct(a));return 0;}
