Introduction
Quality control is a technique used to evaluate objects that people use on a day-to-day basis. This technique is used to evaluate the ingredients in food and see if they are accurate. The objective of this quality control experiment was to examine different acid and base materials and test their pH levels. As a part of the experiment, a procedure was formed to create NaOH and HCl standard solutions and then conduct acid-base titrations to decipher between the acid-base materials. The standard solutions were used to dilute the acid-base materials for the titrations and then test what pH level each one possessed. Titration was used “for determining the quantity or concentration of a substance in a solution” (Dartmouth College, 1997). In this experiment, the substances were the acid or base materials. As a hypothesis, the standard solution NaOH was going to determine the acidic substance and the HCl solution was going to determine the basic substance.
Methods
Materials- As a group, proper lab attire was worn at all times. Once the lab bins were obtained, other materials were retrieved and brought back to the lab bench. The materials included pH strips and reagent chemicals such as phenolphthalein and bromothymol blue. These reagent chemicals emanate a certain color to help determine whether each substance was an acid or a base. According to Senese (1997), Bromothymol turns blue when it comes in contact with a base and phenolphthalein turns pink when it comes in
The purpose of this lab is to test substances and to determine the physical and chemical properties of substances.

The mixture might have contained more or less than 5 drops of bromophenol blue, which might have resulted in the indication of the lab.
The nurse is challenged with the care of patients over a lifespan. Each stage of life brings its own physical and emotional changes which directs the care needs. The care needs of the pediatric patient will be much different from the needs of the geriatric population. The geriatric population has very specific needs which has prompted the government to establish the Quality Assurance & Performance Improvement (QAPI) program. The QAPI provides the framework for nursing facilities to develop and implement changes which address deficiencies the facility was found to have. Also, the QAPI program requires practices and policy be put in place to monitor care of the residents. The purpose of this paper is to list some of the changes the elderly go through as they age, and demonstrate these changes in a quality improvement project. After review of literature, I will discuss the challenges, barriers, and solutions as related to quality improvement. Lastly, I will discuss the quality of care for the geriatric in the future.
By using the pH paper to measure the solutions A through E it would point out what substance is an acid and which one was basic. Also, by adding Bromothymol blue and Phenolphthalein afterwards to the solution it would indicate what color it would turn to when mixed into an acid and a base.
In the preceding chapters basic elements for the proper execution of analytical work such as personnel, laboratory facilities, equipment, and reagents were discussed. Before embarking upon the actual analytical work, however, one more tool for the quality assurance of the work must be dealt with: the
By using acid-base titration, we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein's color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of the range of phenolphthalein.. The methyl red indicator and the phenolphthalein indicator were unsuitable because their pH ranges for their color changes did not cover the equivalence points of the trials in which they were used. However, the
As a part of quality improvement (QI) it is excellent practice for healthcare organizations to gather and analyze data in order to identify areas strength plus areas of weakness to promote improvement in patient care. Hospitals gather and use data to improve patient care. If the facility in this scenario gathered data on NSI’s as part of QI and then presented this information to the staff it could recognize strengths and point of areas of weaknesses. Quality improvement can lead to increases with staff satisfaction. Knowledge of this areas and lead to educational needs and staff awareness which can empower the staff to do better in areas of weakness. In the case scenario, awareness could have led to improvement in restraint use, pressure
And that testing solution should have a ph of 7.5 or lower. If results were less than 200 PPM more sanitizing agent needed to be added and then rechecked. If results were more than 300 PPM more water needed to be added and then checked again. Once sanitizing levels were checked they needed to be indicated on the log form. Lastly, she went over wearing of proper slip-resistant shoes in kitchen.

Briefly discuss one or more ways nurses can become involved in setting and auditing patient care standards or participating in other quality control/improvement activities within their organization.
Lindsey, I am with you. I also think that the total quality control method should be the desirable one in the healthcare services. In the modern world, everywhere, the people give priority to the quality of products and services. This is especially true in the case of healthcare services. By maintaining the quality, we can ensure the safety. According to the Institute of Medicine, there is a direct relation between the improved health services and the health outcomes of people. (United States Department of Health and Human Services: Health Resources and Services Administration, n.d.). The quality improvement is the ongoing process to achieve higher standards of performance. This process analyses the performance and tries to improve it to
orporations measure the quality through statistics and commit to producing products without defect. Companies create stronger leaders and employees when quality control implemented and used properly. By educating employees through training processes followed and corrective actions documented preventing mistakes and production issues. Regulations required by city and state so corporations can distribute goods safely. Without a quality control process, corporations run the risk of delivering defective or contaminated goods. The manufacturing industry needs specific regulations and quality control measures to protect consumers, protect product integrity, and the environment.
2. Statistical process control (SPC) involves inspecting a random sample of the output from a process and deciding whether the process is producing products with characteristics that fall within a predetermined range. SPC answers the question of whether the process is functioning properly or not. 3. Acceptance sampling is the process of randomly inspecting a sample of goods and deciding whether to accept the entire lot based on the results. Acceptance sampling determines whether a batch of goods should be accepted or rejected. The tools in each of these categories provide different types of information for use in analyzing quality. Descriptive statistics are used to describe certain quality characteristics, such as the central tendency and variability of observed data. Although descriptions of certain
