33. One reason that we have such a complex system of belts/zones/storms in Jupiter’s atmosphere is that:

4. The south celestial pole and the north celestial pole lie in the sky directly above

Muscles get energy needed to fuel activity from all of the following except:

4. If no one has ever visited the core of the Earth, how do we know that it is made of metals?

19. One way to measure how long Jupiter takes to rotate is to watch the giant storms in its atmosphere go around. A more fundamental way to measure the rotation is to:

A nurse is assessing an 86 year-old-client client after she returns from abdominal surgery. The nurse checks pre-operative vital signs at 0830 and compares them with the current vital signs at 2230.  After analyzing the assessment data, what action will the nurse take first?  Vital Signs 0830 2203 Pulse 80 90 Respirations 16 18 Blood pressure 90/60 100/80 Temperature 99.5F 97.1F

A 42 year old client has been admitted to the medical surgical unit following 72 hours of severe vomiting and diarrhea. He hasn’t been able to hold down more than a few sips of water at home. Labs were drawn and his results are show below. Which IV fluid is this client most likely to receive as continuous fluid replacement?  Lab Result BUN 26 Creatinine 0.9 Hematocrit 58% Sodium 152 Potassium 3.3

You are developing an application that allows the user to complete sandwich orders. The user must first select a type and side, then enter the quantity of sandwiches and price per sandwich. Finally, the user must click the calculate button. Given the provided template, write the code to meet these requirements: The user should be able to change the sandwich and amount controls until clicking calculate. When the user clicks Calculate: a. Validate a numeric value that was entered and display any errors using a message box. b. Use selected radio button and combo-box values to concatenate and display a summary. c. Use entered textbox values to calculate and display cost. When the user clicks Clear, clear the textbox, label value and radio-button, combo-box selection. When the user clicks Exit, terminate the application.   Directions: Please copy the supplied code below into your answer to this question. Use the spaces to write the missing code and complete the program.   namespace MidtermExam{    public partial class frmOrder : Form    {        // Class-level declarations         // Declare decimal constant for Sales Tax Rate of 6% (1 point)         // Declare integer variable for Quantity (1 point)         // Declare decimal variables for Price, Tax, SubTotal and Cost (1 point)         public frmOrder()        {            InitializeComponent();        }         private void btnCalculate_Click(object sender, EventArgs e)        {            // This procedure calculates the total cost and displays them to the user.             // Get the quantity of sandwiches as input from the user.            //  and Verify that the value is integer and not less than zero. (1 point)            if ( )             {                 // Get the price of each sandwich as input from the user.                // and Verify that the value is decimal and not less than zero.
