SBAR report from day shift nurse:

Situation: Mrs. Jacobson is an 85-year-old white female who was admitted last evening after falling and fracturing her hip. X-rays have been taken and show left intertrochanteric hip fracture. Mrs. Jacobson is scheduled for surgery tomorrow.

Background: Mrs. Jacobson has a 10-year history of osteoporosis, and her daughter reports that recently Mrs. Jacobson has been having dizzy spells.

Assessment: Mrs. Jacobson's vital signs are stable. Her pain is under control with morphine every 4 hours, and I medicated her at 1400. Her pain level was 2 after the morphine. The skin is intact; color and sensation around the hip area are within normal limits. A Morse Fall Scale assessment was completed on admission, and her score was 45. Fall precautions were implemented.

Recommendation: You will need to reposition Mrs. Jacobson as she needs to be turned every 2 hours. You should perform a focused musculoskeletal assessment, reinforce safety, and provide patient education on fall risk. Assess her pain level and medicate for pain if needed.

A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate the volume of household bleach that should be diluted with water to make 500.0 mL of a pH = 10.00 solution. Use the Ka of hypochlorous acid found in the chempendix.Ionization Constants

A)Which of the following is NOT a valid boundary condition for a particle inside a 1D box of finite length L? For this problem, assume that the potential energy outside the box is infinite.

1-When x = 0, PHI = 0.

2-The particle can only be inside the box.

3-The wave function is complex.

4-If the wavefunction is normalized, the integral of the complex conjugate from 0 to L will be 1.

Lester Hollar is vice president for human resources for a large manufacturing company. In recent years, he has noticed an increase in absenteeism, which he thinks is related to the general health of the employees. Four years ago, in an attempt to improve the situation, he began a fitness program in which employees exercise during their lunch hour. To evaluate the program, he selected a random sample of eight participants and found the number of days each was absent in the six months before the exercise program began and in the last six months. Below are the results.

At the .05 significance level, can he conclude that the number of absences has declined? Estimate the p-value.

a. State the decision rule for 0.1 significance level: H₀ : μ_d≤ 0; H₁ : μ_d > 0. (Round the final answer to 3 decimal places.)

Reject H₀ if t > _________

b. Compute the value of the test statistic. (Round the final answer to 3 decimal places.)

Value of the test statistic: ____________

c. Estimate the p-value? (Round the final answer to 4 decimal places.)

p-value: ____________-

d. What is your decision regarding H₀?

At the 0.05 significance level,  (reject or do not reject?)  H₀.

2. The company declared and paid a property dividend of land that had a book value of $20,000 and a fair market value of $80,000 to common shareholders on June 3.

3. The company used the treasury method to retire 2,000 shares when the market price was $34 per share.

1.   Bubble Sort
Implement a bubble sort program that will read from a file “pp2.txt” from the current directory a list of intergers (10 numbers to be exact), and the sort them, and print them to the screen. You can use redirection to read data from a given file through standard input, as opposed to reading the data from the file with the read API (similar to Lab #1). You can assume the input data will only have 10 numbers in the file, and that the numbers will be valid integers. You must implement 3 functions, including main(), bubblesort(), and swap(). The function declarations are included, and they must be followed exactly to receive full points. All your code should be contained in the bubblesort.c file, and the Makefile.

Usage:./sort
For example, if you type:
./sort
INPUT: 1 3 2 8 4 9 8 3 10 14
OUTPUT: 1 2 3 3 4 8 8 9 10 14

Bubblesort.c:
#include <stdio.h>
void bubblesort(int [], int);
void swap(int*,int*);

int main()
{
   printf("edit the bubblesort.c file to implement your bubble sort\n");
   return 0;
}

The file that should be read:

pp2.txt:

1 3 2 8 4 9 8 3 10 14
