AUCS 340: Ethics in the Professions Medical Ethics Case Study You work as a registered nurse in a busy urban emergency department. Today you are caring for an adorable four-year old female patient who presents with a broken right arm and several bruises around her abdomen. You suspect that this patient is a victim of accidental trauma (child abuse). If you report your suspicions to the proper authorities, your state laws mandate that the child be removed from the care of the parents until an investigation of the allegation is complete. You know that this may take up to a week. Answer the following questions. 1) What type of ethical problem is this professional facing and why? 2) What steps should this medical professional take and why? 3) What would be the result of the nurse’s actions if this child is found to have a genetic problem and it is not a case of child abuse? 4) Are there other types of professionals who may also be required to report cases of suspected child abuse? If yes, what type of professional would that be? 5) What would you do in this situation?

PHSX 220 Homework 13 D2L – Friday April 28 – 5:00 pm SHM and Pendula Problem 1: Shown below are 6 identical masses attached to springs and hung vertically. The masses are pulled down various distances and then released. The spring constant (k), spring sti ness, and the distance (d) that the mass is pulled down from its equilibrium position are given for each situation. The expression relating k and m to the angular frequency of the system is the same for both a horizontal and vertical spring-block system. Rank the situations based on the time it takes the mass to get from its maximum height to its minimum height from greatest to least. Problem 2: Shown below are systems containing a block resting on a frictionless surface and attached to the end of a spring. The springs are displaced to the right by a distance given in each gure and then released from rest. The blocks oscillate back and forth. The mass and spring constant are given for each system. Rank the cases based on the frequency of oscillation from greatest to least. Problem 3: Shown below are six masses hung on the ends of strings forming a pendulum. The masses have been pulled to the side and released so that they are swinging back and forth. For each pendulum the diagrams give the mass of the swinging object, the frequency of the swing, and how far, in terms of the angle from the vertical, that the masses were initially pulled to the side. Rank the six cases based on the length of the string from greatest to least. Problem 4: Shown below are four spring-cart systsems that consist of a spring connected to a cart. All systems are shown with the cart located at the equilibrium position. The cart is resting on a horizontal frictionless surface. If the cart is pulled to the right a small distance and released, the mass will oscillate back and forth. The amplitude of oscillation, mass of the cart and spring constants for the four cases are provided in the gure. Rank the cases shown based on their frequency of oscillation from greatest to least.
