How to validate Credit Card Numbers? Most credit card number can be validated using the Luhn algorithm, which is more or a less a glorified Modulo 10 formula! The Luhn Formula: • Drop the last digit from the number. The last digit is what we want to check against • Reverse the numbers • Multiply the digits in odd positions (1, 3, 5, etc.) by 2 and subtract 9 to all any result higher than 9 • Add all the numbers together • The check digit (the last number of the card) is the amount that you would need to add to get a multiple of 10 (Modulo 10) Luhn Example: Steps Total Original Number: Drop the last digit: Reverse the digits: Multiple odd digits by 2: Add digits from line above Add all numbers: Mod 10: (85 + X) modulo 10 = 0 , thus X=5 (last digit of card) List of credit card number formats Credit Card Issuer Starts With ( IIN Range ) Length ( Number of digits ) American Express 34, 37 15 Diners Club - Carte Blanche 300, 301, 302, 303, 304, 305 14 Diners Club - International 36 14 Diners Club - USA & Canada 54 16 Discover 6011, 622126 to 622925, 644, 645, 646, 647, 648, 649, InstaPayment 637, 638, 639 16 JCB 3528 to Laser 6304, 6706, 6771, Maestro 5018, 5020, 5038, 5893, 6304, 6759, 6761, 6762, MasterCard 51, 52, 53, 54, Visa Visa Electron 4026, 417500, 4508, 4844, 4913, Data to Evaluate Simplified Issuer Codes for Final Project: VISA: 45 44 MasterCard: 51 53 American Express (AMEX): 37 34 Discover: 60 JCB: 31 33 Diners Club - North America: 54 55 Diners Club - Carte Blanche: 30 Diners Club - International: 36 Maestro: 58 LASER: 67 Visa Electron: 48 49 InstaPayment: 63 Final Project - Credit card numbers and the case of Mobius Duck How to validate Credit Card Numbers?

The first search was conducted on a general browser that yielded several results. It was then performed on reputable journal databases, including MEDLINE, Elsevier, and PubMed. Some websites were also identified to provide relevant information about the topic, and they were included in the literature review. A search of the reference list of the identified articles was also performed to find additional eligible articles.
Nursing fatigue has adverse impacts, including taking a toll on patient care. Sharon Weinstein notes that the healthcare of nurses determines the quality of care patients receive (Weinstein, 2020). Therefore, it is essential for healthcare organizations to address nursing fatigue at appropriate times to avoid the adverse impacts of the issue. Nurse fatigue is an impediment to the quality of care nurses offer. Various factors cause nursing fatigue, including the practice environment.
Environmental factors leading to nurse fatigue include long work hours, distressing patient events, physical or mental factors causing fatigue, and low hours of sleep (Knupp et al., 2018). Good nurse manager ability plays a vital role in addressing the issues experienced by the healthcare professionals. Nursing fatigue is a significant challenge to the wellbeing of care providers. According to Kolthoff & Hickman (2017), geriatric nurses have a higher chance of developing compassion fatigue and burnout because of their exposure to a lot of suffering and loss. The authors identified an average prevalence of burnout and compassion fatigue with unmatched compassion satisfaction.
The lack of measures to address nurse fatigue causes other challenges like absenteeism or nurse turnover. Nurse fatigue is dangerous to both patients and nurses. The impact of nursing fatigue is a reduced ability to perform one’s responsibilities (Ulrich, 2018). Patients who rely on primary care providers are at risk because of issues like medication errors or incompetence that could jeopardize the health of patients. Nurses also face a threat when they do not take necessary precautions to address the health issues they face.
The culture adopted in organizations determines the dedication allocated to address the needs of its professionals. The common causes of nurse fatigue include declined nurse satisfaction, negative patient outcomes, and heavy workloads. However, addressing nursing fatigue faces a challenge from the culture in the profession (Steege & Rainbow, 2017). The ‘supernurse’ culture indicates that nurses and their organizations play a crucial role in addressing the challenge through adopted cultures. The physical health environment of nurses determines the nursing fatigue and wellbeing of the professionals.
According to Wingler and Keys (2019), the physical environment of a nurse can determine whether their wellbeing improves or deteriorates. The organizational environment should always strive to ensure that nurses have the most conducive work environments to nurse fatigue and other health complications. It is also essential to the wellbeing of patients. The working routines of nurses also determine their compassion fatigue and should be addressed to ensure their wellbeing. The responsibilities of a nurse are multidimensional and can cause fatigue in the professionals.
Nurse leaders can address this through the identification of efficient work schedules that will mitigate nurse fatigue. According to Min et al. (2019), work schedules have proven to be the most effective interventions for healthcare managers to ensure the wellbeing of their nurses. Addressing nursing fatigue is essential to the wellbeing of nurses and their patients. The American Nurse suggests a series of interventions to address nurse fatigue, including scheduling and self-management. The article emphasizes the significance of personal initiative in addressing nurse fatigue.
The early identification of nurse fatigue is essential in effectively addressing the issue. According to Kelton et al. (2014), it is essential that both nurses and their supervisors note the identifiers of nurse fatigue early to avoid its adverse consequences in later stages. The measure is preventive and effective for the healthcare providers. References American Nurse. (2020, July 14). American nurse: The Official Journal of the American Nurses Association (ANA) .

Nurse Fatigue Thesis+introduction Nurse fatigue is a daunting problem that has been widely regarded as a threat to both nurse and patient health. Nurse exhaustion is described as an emotional feeling, mental or genuinely feeling drained or exhausted due to nursing demands ("Fighting the Effects of Nurse Fatigue," 2017).
Nurse exhaustion is common due to high-strength responsibilities, a lack of sleep, and long work hours (Steege & Rainbow, 2017). Institutions are abstracts, and their efficacy and success depend on the persons entrusted with the responsibility of seeing the provision of services in such institutions; the healthcare system is not an exception to this deposition. Nurses are often exposed to extreme sadness and misfortune, which has been linked to the development of burnout fatigue. Sympathy exhaustion refers to a lack of business-related satisfaction, but it may also refer to situations where the job brings more pain than happiness. The risk of empathy exhaustion varies from one nurse to the next, depending on their level of involvement and their role, with those dealing with more mature adults being at higher risk.
Kolthoff & Hickman (2017) found that average levels of burnout, compassion fatigue, and compassion satisfaction were recorded by forty two nurses working on a geriatric medicine unit in an exploratory, descriptive study on compassion fatigue, compassion satisfaction, and burnout. Nurse fatigue affects the nurses' ability to deliver and reduces the quality of service issued to the patients, thus affecting the health outcome, and the new nurses who still have less experience are the most affected. There is a need for deliberative administrative and personal efforts to reduce nurse fatigue. These efforts by the nurses include having a sufficient sleep and on the side of the administration checking on the working hours of every nurse.

Final Project: Validating Credit Card Numbers using the Luhn Algorithm
Overview
In the digital age, verifying credit card numbers is a critical task to prevent fraud and maintain data integrity. This project utilizes the Luhn algorithm to validate a collection of credit card numbers and identify their issuers. The task includes reading data from a file, validating credit card numbers, and writing the results into separate files for valid and invalid cards. The completion of this project will demonstrate your understanding of programming concepts, algorithms, and data processing techniques, particularly in Java.
Problem Statement
You are tasked with implementing an application to validate credit card numbers for an investigation into a case known as "Mobius Duck." The main objectives are as follows:
1. Evaluate each number against the Luhn algorithm to determine validity.
2. Identify the issuer of each valid credit card number.
3. Store valid and invalid numbers in separate arrays.
4. Write valid numbers into `valid_cards.txt` and invalid numbers into `invalid_numbers.txt`.
Luhn Algorithm
The Luhn algorithm, also known as the modulus 10 algorithm, is a straightforward checksum formula used to validate a variety of identification numbers, including credit card numbers. The steps for using the Luhn algorithm are as follows:
1. Drop the last digit of the number (this is the check digit).
2. Reverse the digits of the number.
3. Multiply odd-positioned digits by 2. If the resulting product is greater than 9, subtract 9.
4. Sum all the digits together.
5. The check digit is valid if the result is a multiple of 10.
Implementation
Java Classes
The main application will consist of three Java classes: `CreditCardValidator`, `CardIssuer`, and `Main`.
1. `CreditCardValidator` Class: This class contains methods to validate credit card numbers using the Luhn algorithm and determine the issuer based on predefined starts with (IIN) codes.
2. `CardIssuer` Class: This class maintains the issuer information and provides a method to get the issuer based on the card number.
3. `Main` Class: This class serves as the driver, handling file input/output and coordinating the validation process.
Code Example
Here is a snippet of how the implementation would look:
```java
import java.io.*;
import java.util.*;
public class CreditCardValidator {
public boolean validateCardNumber(String cardNumber) {
int total = 0;
boolean alternate = false;
for (int i = cardNumber.length() - 1; i >= 0; i--) {
int n = Integer.parseInt(cardNumber.substring(i, i + 1));
if (alternate) {
n *= 2;
if (n > 9) {
n -= 9;
}
}
total += n;
alternate = !alternate;
}
return (total % 10 == 0);
}
public String getIssuer(String cardNumber) {
Map
cardIssuers.put("34", "American Express");
cardIssuers.put("37", "American Express");
cardIssuers.put("51", "MasterCard");
cardIssuers.put("52", "MasterCard");
cardIssuers.put("53", "MasterCard");
cardIssuers.put("54", "MasterCard");
cardIssuers.put("55", "MasterCard");
cardIssuers.put("40", "Visa");
cardIssuers.put("41", "Visa");
cardIssuers.put("45", "Visa");
cardIssuers.put("60", "Discover");
for (String prefix : cardIssuers.keySet()) {
if (cardNumber.startsWith(prefix)) {
return cardIssuers.get(prefix);
}
}
return "Unknown Issuer";
}
}
```
