Nearing the end of her 18-hour work shift, a resident sees a patient with extremely high blood glucose levels. She writes the patient a prescription for insulin; however, in her exhaustion, she closes her "U" (for "units"), and it looks more like an extra zero. As a result, the pharmacist dispenses an insulin dose that's ten times stronger than the patient needs. Which of the following is a latent unsafe condition in the system that contributes to the resident's error? - Answer long ...

Swiss cheese model of accident causation - Answer Serious adverse events are almost always the result of multiple failed opportunities to stop a hazard from causing harm Latent conditions - Answer defects in the design and organization of processes and systems — things like poor equipment design, inadequate training, or insufficient resources. These errors are often unrecognized, or just become accepted aspects of the work, because their effects are delayed. Active failures - Answe...

Swiss Cheese Model - Answer of accident causation idea that harm is caused by a series of systemic failures in the presence of hazard. the cheese is a level of safety system: usually effective because the holes don't line up When the hole line up: cause hazards What are latent condition - Answer defects in the organization of processes and systems ie. inadequate training, limited resources, poor equipment these are all often overlooked because of delayed effects Wha...

According to WHO, in developed countries worldwide, what is the approximate likelihood that a hospitalized patient will be harmed while receiving care? - Answer 10% According to WHO, in developed countries up to 10 percent of hospital patients may be harmed while receiving care. Since the publication of To Err Is Human in 1999, the health care industry overall has seen which of the following improvements? - Answer Wider awareness that preventable errors are a problem More than a d...

Which of the following is a latent unsafe condition in the system that contributes to the resident's error? - Answer Long Work Schedule To prevent this problem from happening again, which of the following would be the best course of action? - Answer Develop a system that prevents messy handwriting from causing miscommunication that leads to error. "Latent errors" are best defined as: - Answer Defects in the design and organization of processes and systems. What is the active...

electromyography - Answer tool used in both research and clinical settings to identify muscle activity electromyogram - Answer electrical signal associated with muscle contraction EMG recording requirements - Answer -electrodes (detects myoelectric signal; function as transducers) -amplifier (small amplitude of myoelectric signal requires amplitude to allow for interpretation) transducers - Answer join circuit for ion flow within muscle and electron flow in recording equipm...

What processes sensory information ? - Answer Central Nervous System What information is being provided to the CNS for processing? - Answer Sensory input from periphery How does the CNS respond to sensory input from periphery? - Answer Used to make appropriate motor output What phenomenon is the CNS considered to be & why? - Answer "Black Box" - Internal processes are inferred (inability to measure internal processes) What is one primarily focused on for informati...

Attention - Answer -selectively concentrating on a particular stimulus while ignoring other perceivable information -attention is a *limited resource* types of stimuli - Answer 1. exogenous attention = external (bottom - up) ex: alarms, stop light, touching a hot stove, etc. 2. endogenous attention = internal/intention (top - down) ex: having a conversation during the middle of a loud party or consciously paying attention and deciding how to interpret braille attentional/change...

What is Motor Learning? - Answer the study of the acquisition and/or modification of movement Changes in internal process that determine an individual's capabilities for performing a motor task Motor Skill - Answer an activity that requires voluntary movement to achieve a goal Skill acquisition - Answer learning the knowledge and skills necessary for effective performance Skill refinement - Answer Learner has discovered the most effective way to perform this task and i...

why is the CNS considered to be a "black box"? - Answer due to its inability to measure internal processes the information processing model is primarily focused on... - Answer reaction time 3 stages of information processing? - Answer stimulus identification response selection response initiation/programming simple reaction time - Answer 1 stimulus, 1 response ex: light stimulus and press a key 200ms Go/No-go reaction time - Answer 2 stimulus, 1 response ex:...
