ion A: You are a home health care nurse. One of your patients is Frank, a 75 year old man that smoked most his life and now lives alone. You notice that he is losing weight. When asked about eating, he says that "food just doesn't taste right any more". Explain what has happened to Frank's senses to cause this problem. (2 pts)

Smoking reduces the sensitivity of your taste buds by decreasing the taste receptors degree along with having an effect on the sensory nerve. Taste buds of smokers tend to be flatter. When you breathe in, the olfactory nerves send signals to the brain, signaling what you are smelling. Unfortunatley when you breath in cigarette smoke you are causing damage to the olfactory nerves causing them not to be able to register the aromas of foods and other items. Smoking can also result in weight loss by increasing the metabolic rate, decreasing metabolic efficiency, or decreasing caloric absorption.

Situation B: Debbie is a 40 year old slightly overweight woman with Type II diabetes. She has high blood pressure and chronic high blood sugar levels. Why did her primary care physician insist that Debbie visit an eye doctor even though Debbie has never worn glasses? (list at least 2 different disorders that may be involved). (2 pts)

Debbie may have cataracts or glaucoma.

Situation C: Ron is a 47 year old Army veteran with a hearing impairment. Consider the pathways of hearing and answer the following questions:
1. What are the two major categories of hearing loss? (include the structure impaired in each case) (2 pts)
Conductive Hearing Loss ( inner ear- cochlea) and Sensorineural hearing losses (outter ear/ middle ear- external auditory canal/ auditory ossicles)

2. Describe how the Weber & Rinne tests work to differentiate these two disorders. (2pts)

For Rinne: The doctor strikes a tuning fork and places it near the base of your

Ear Cropping Research Paper

...Ear Cropping Puppies Quick, think of a cute Doberman pinscher or Great Dane puppy. Now think of that same puppy under anesthesia. Next to a veterinarian who has a scalpel in their hand prepared to cut away the pinna, "the outer thin membranous part of each ear from the base, around the outside and up to the tip" (Admin, 2010). Imagine the thought that will run through that puppies mind when it wakes up confused and its ears in pain. The procedure just explained is ear cropping, preformed on many breeds of puppies aged 6-12 weeks. It is a purely cosmetic procedure endorsed by the American Kennel Club (AKC). The purpose of this paper is to explain why ear cropping is an unnecessary procedure done for selfish human pleasure. Soon after the American Veterinary Medical Association announced in 2008 "The AVMA opposes ear cropping and tail docking of dogs when done solely for cosmetic purposes. The AVMA encourages the elimination of ear cropping and tail docking from breed standards" (Nolen, 2008), the American kennel club...

Ear Irrigation Research Paper

...The medical assistant is usually directed to perform an ear irrigation on a patient who may have a buildup of cerumen (earwax) in the ear that cannot be removed with a cotton-tipped swab. The swab may push the cerumen deeper into the ear canal, which may become lodged and hardened and making it feel uncomfortable in the individual’s ear, which may also impair their hearing. The irrigation is performed to remove the excessive amount of earwax. Periodically it may be necessary for the medical assistant to first insert a softening solution into the ear to soften the cerumen before starting the irrigation process. Auditory acuity is performed to test the patient’s ability of the ear to perceive sound. Auditory problems might be simple, but if...

Real Ear Measurements Research Paper

...Real Ear Measurements….Do I Need This? Absolutely. If you currently wear hearing aids or are thinking about getting them, you need to know about Real Ear Measurements (REM). It is the main difference between being happy with your hearing aids or still struggling to hear the people and sounds you love. The size and shape of each person’s ear canal is unique to them, like a fingerprint. Recognized as part of the “Gold Standard” of Hearing Care, Real Ear Measurements use a probe tube and a data driven method to confirm that the hearing aid matches the unique “fingerprint” of each person’s ear. It takes extra time, but doing it the right way assures the patient that their hearing aids are delivering maximum benefits, without being too loud...

Visual

...Abstract This paper was written to describe the impact of visual and hearing impairments on student’s academic achievement to teachers and other educators. Having knowledge of these impairments allows the teacher to better serve students with these impairments in the classroom. Hearing and Visual Impairments Hearing and visual impairments have a major impact on a person’s development and academic achievement. Hearing and seeing are critical to speech and language development, communication, and learning. The earlier in a person’s life that they develop or have these impairments, the more serious the development of the person will be effected. In the same manner, the earlier that the problem is identified and intervention begun, the less serious the impact on that person’s development may be (American Speech Language Hearing Association, 2011). Hearing Impairments Hearing impairments are defined as the decreased ability to hear and differentiate sounds. This can range from mild hearing loss to total deafness (March of Dimes, 2010). Humans are able to hear sounds through the brains relationship with the ear. The outer ear absorbs sound waves that travel through the eardrum. These sound waves are then transferred to the middle ear before entering the cochlea. The cochlea is the main receptor organ for hearing and works with inner ear canals that assist with balance to hear and register sounds to the brain. Before an educator can differentiate or modify lesson plans they must...

This I Believe: Loud Music Causes Hearing Loss in Teens

...Logan Nelson Pd.2a Mrs. Downey 5/5/14 English 9 This I believe :Loud music causes hearing loss in teens IPods and MP3s are very important to teens today. We listen to them while we get dressed and on our way to school. We try to sneak our ear buds in during class; we listen after school, while doing our homework, and before bed. IPods and MP3 players have become an important part of the daily schedule, but what teens don't realize is those same devices that entertain us for hours each and every day can be a serious source of hearing loss Most teenagers believe that listening to music for long periods of time is perfectly fine. According to the American Osteopathic Association (AOA) teens should not listen to music for more than one hour every day at a reasonable volume. The reasonable volume for music is 75 decibels witch is about 70% of an IPods volume capacity according to the National Center for Biotechnology Information The effects of frequently listening to loud music include permanent hearing loss. The hair cells in the ear – irreplaceable cells that send electrical impulses to the brain – can die from sustained abuse. After going to a rock concert or listening to a lot of loud music, you might hear a soft ringing in your ears called tinnitus. This is an indication of acoustic trauma that over time could result in hearing loss if precautions aren't taken. Many people think that hearing loss is hereditary but “acoustic trauma produced by exposure to loud sounds” is...

Hearing Assistive Devices

...Hearing Assistive Devices There are several types of hearing loss, which can lead to the need for a hearing assistive device. The types of hearing loss are as follows: Conductive hearing loss, Sensorineural hearing loss, Mixed hearing loss, Central and Functional hearing loss. Conductive hearing loss is when there is not enough sound getting thorough the outer and middle ear. Sensitivity to sound is diminished, but clarity is not changed as long as the sound is loud. Sensorineural hearing loss, sound is flowing normal through the outer and middle ear, but there is impairment in the inner ear auditory nerve (CN VIII) causing hearing loss. A problem with sensorineural lose is that sound is heard, but the person doesn’t understand speech. Mixed hearing loss is a combination of conductive and sensorineural. Central hearing loss is a problem in the central nervous system involving the inability to interpret sound. Functional hearing loss is caused by an emotional or psychological factor in which there is no physical finding of hearing loss (Lewis et al., 2011) Mosby and Elsevier (2009) (Crusse & Kent, 2013). To determine the type of hearing loss, type of hearing device needed and proper fit, there are different doctors with different levels of education a person can see. Choosing a correct hearing specialist is important. An Audiologist can identify and access hearing disorders. They can also select and correctly fit hearing aids. Audiologists can also program cochlear...

Boy Behind a Wall

...Of the paintings from Zimmerli Museum that I may write about, I choose the one of the little boy. In my paper, I will verbally explore every aspect of this portrait. The focus of this painting is a young child, roughly 10-11 years in age. He is dressed solemnly in a cream-colored t-shirt layered with a grayish-green button-down, collared shirt, matched in color to his pants, along with a simple brown belt. He is a brunette with big brown doe eyes, and the dark, inky color of his hair and eyes sets off the rather paleness of his skin. His eyes are very prominent and immediately grab your attention, while his thin rose colored lips seem to disappear into a thin line as one stares into the holes of his eyes. His ears seem to be on the larger side for a boy his size, suggesting an extra sense of hearing and understanding. Slouched on a brown, most likely wooden, chair, he stares deeply past the viewer. He relaxes very comfortably in the chair, comforted by the closeness of his shadow. As one looks into his eyes, you can tell he is seeing far away. Hopeful is a word that could be used to describe the emotion one can feel from his eyes. It is if he is waiting for something or someone. His laid-back posture suggests that he has been waiting a very long time, and since there is no hurry in his demeanor, one senses that he will continue to be waiting a long time. Despite his young age, the boy radiates patience, with no signs of worry or distress. One can imagine that this...

Comp Paper 2

...Introduction to Speech M/W 1:30 Listening Activity Paper 4/27/2015 First allow me to say that I was truly dreading this assignment. I thought to myself, “How am I going to devote 12 hours of any given day to this?” I am just so busy. However, I learned a lot in a short period of time about myself. I realize I was wrong about myself. I truly thought that I was, at all times, a kind and gracious listener. God knows I have preached to my children enough about how important it is to really listen to people. Now I wonder if they take me seriously when I say that. I did not realize how focused I get about our structure and routine. Being a single mom with two honor roll students who are very involved requires structure. I did not realize that when I am in that zone I am literally tuning them out and dismissing what they are expressing to me. This must make them feel pretty unimportant. It also begs the question, will they feel justified tuning me out. I am not aggravated when I am focused on getting things done but I fear I come across that way in my direct and impersonal responses and lack of listening. I also did not realize that I was prioritizing listening to one child over the other according to the time I have with each. I have literally subconsciously been scheduling time to listen to each of them. That means that if the Sienna feels it is important to tell me something during Aidan’s primary time in the car, I may or may not dismiss her. How awful...

Causal Analysis Paper

...Courtney Bunn 21 November, 2014 101 C Causal Analysis According to the Merriam-Webster Dictionary hearing is the “process, function, or power of perceiving sound”; now imagine if that power were gone. Hearing loss is a continuing problem in the U.S. resulting in 28 million Americans having some degree of hearing loss (Noise-Induced 1). There is not just one simple cause to this complex problem; hearing loss can be caused by multiple things such as a disease, aging, or noise. In this paper, I will be discussing how diseases, medication, genetics, aging and noise levels all have an effect on a person’s ability to hear. When we normally think of people who have lost their hearing we tend to think of the elderly. Aging is most definitely a...

Then I will write a paper that describes adaption and how I experienced it in my experiments. The paper will cover the following. I will fully describe process and results of the experiments that I chose. I will also answer what is sensory adaptation. Then I will explain the concept of sensory adaptation, and refer to my text for the definition of sensory adaptation. Next I will explain how adaptation is evident in each of my experimental results. I will provide a comprehensive description of the sensory systems that are involved in the experiments that I performed. This description will include what happens from the receptors to the brain. My discussion will illustrate what was experienced in each experiment. Finally I will discuss how adaptation is important from an evolutionary perspective. Psychology p.3 There are three experiments I will conduct and they are as fallows.

Steven Church Auscultation

...He first introduces the stethoscope and its importance through a text of imagery, contending that “when it touches you, it sings sounds of your body, noises you can barely imagine – the hypnotic pump of organs, the soft ebb and flow of lungs at work – noises that can name you normal, healthy, or not. The intimate instrument – the stethoscope – knows your body in a way your own hands and ears never can” (73). Contradictory to the idea that the application of technology can be harmful to the world, Church begins to establish the great advantage that instruments, such as the stethoscope, can offer. With a stethoscope, doctors can effectively apply the process of auscultation, consequently improving medical procedures and saving the lives of several patients. But while it may appear that Church’s approach is conflicting, the stethoscope actually diverts from complete automation. In truth, the role of a stethoscope fundamentally extends a doctor’s ability to hear. Inventions such as the stethoscope cannot function on their own; they need the intellect and skill of a doctor to be whole (Church 91). In such cases, the stethoscope undeniably...
