CHAPTER 8 Cost-Volume-Profit Analysis ANSWERS TO REVIEW QUESTIONS 8-1 a. In the contribution-margin approach‚ the break-even point in units is calculated using the following formula: Break-even point = fixed expenses unit contribution margin b. In the equation approach‚ the following profit equation is used: sales volume ⎞ ⎛ unit variable sales volume ⎞ ⎛ unit fixed ⎜ ⎟ −⎜ ⎟ − ⎜ sales price × ⎟ ⎜ expense × ⎟ expenses = 0 in units ⎠ ⎝ in units ⎠ ⎝ This equation is solved for the sales volume in units

we are laying in bed asleep‚ sitting listening to a teacher‚ or walking down the hallway‚ the cardiovascular and respiratory systems work together to regulate oxygen and waste throughout the body. When an activity becomes strenuous for a prolonged period of time‚ these systems must adapt to increase the capabilities of oxygen and waste management. The main function of the respiratory system is the exchange of gases with

Analysis Paper: Fluid Volume Deficit “Fluid volume is a term that describes the balancing of input and output of fluid in the body” (Welch 2010). This balance can be affected by many factors: inadequate intake‚ shock‚ vomiting‚ diarrhea‚ or too much output. It can also be caused by third spacing. Fluid volume balance is very important to monitor patients because it can affect every body system and can easily be altered. Fluid volume deficit is more commonly referred to as dehydration.

REPSIRATORY DEPTH Depth- amplitude of each respiratory movement The depth of ventilation refers to the amount of air that is inhaled and exhaled. The amount of air inhaled and exhaled in one cycle is called the tidal volume. The more the chest cavity expands‚ the greater the depth of the ventilation. Full expansion of the chest wall with full relaxation on exhalation is a good indicator of adequate depth of breathing and adequate tidal volume. Many books will try and apply numbers in milliliters

anatomy and physiology of the respiratory system to be able to carry out a respiratory assessment. It is essential that nurses are able to recognise and assess symptoms of respiratory dysfunction to provide early‚ effective and appropriate interventions to improve patient outcomes. It is necessary for a nurse to have a comprehensive knowledge base of the anatomy and physiological process of a healthy functioning pulmonary system‚ in order to carry out a respiratory assessment (Jenkins‚ 2003‚ p124

Respiratory System WebQuest Introduction The primary function of the respiratory system is to supply the blood with oxygen. The respiratory system does this through breathing. Breathing is a natural process that we use to obtain oxygen‚ unlike eating or drinking to get energy. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The respiratory tract is responsible for taking the gases

find myself increasingly more interested in knowing how and why these clinical advances become the best practice in rehabilitating individuals. As a Respiratory Therapist‚ my rehabilitation practice is not as traditional as other Allied Health rehabilitation experience. Many of my respiratory clients are individuals requiring some sort of respiratory support; either with invasive mechanical ventilation‚ inhaler treatments or non- invasive support such as BIPAP/CPAP therapy. Rehabilitation of a ventilated

Respiratory syncytial virus (RSV) Introduction of the Lungs: The primary role of our respiratory system is the exchange of gases in our blood stream. As we inhale our lungs take in Oxygen (O2)‚ as we exhale our lungs release Carbon Dioxide (CO2). The major parts of the respiratory system consist of; The upper respiratory tract consists of the nose‚ sinuses‚ mouth‚ larynx and throat. The lower respiratory tract consists of trachea‚ bronchial tubes and the lungs. The right lung

do any daily activities‚ you wouldn’t be able to walk or run anywhere because you wouldn’t have the energy to move. If you didn’t intake any energy it wouldn’t just affect the way that you live your life‚ it would affect your internal organs as they wouldn’t be able to work. The body may also need energy for when you become ill. When you are ill your body wastes energy trying to get better. So it requires more energy when it is ill so you can still complete your daily activities while being ill
