Chapter 18 Practice Quiz 2 1. Heart valves function to A. pump the blood B. prevent clots from entering the heart C. direct the blood flow through the heart D. measure the blood pressure 2. The right and left atrioventricluar valves open when the A. atria contract B. papillary muscles contract C. atria relax D. ventricles contract 3. During atrial systole, the upper chambers contract and open the AV valves so that blood can be pumped into the A. ventricles B. veins C. atria D. arteries 4. Blood flows past the aortic semilunar valve when the contracts.
However, can cause myopathy which can lead to rhabdomyolysis. Unexplained muscle pain should be reported. Can also cause an elevation of liver enzymes and these may be monitored periodically. Generally will not see a statin and a fibrate given concurrently due to the increased risk of rhabdomyolysis and
Year 10 Pre-Diploma Biology Heart Dissection Introduction This lab practical allows you to identify and compare the size, shape and tissue type of the major chambers and vessels of the heart. The goal of the lab is not just to observe anatomy, but to associate structure with function. The heart is a pump for blood that comes into the right atrium, goes out to the lungs through the right ventricle, returns through the left atrium, and leaves again through the left ventricle - a double circulation. Each chamber is separated by valves that prevent the backflow of blood. Try and figure out where the various components are, how each works, especially how the shape, composition, and even texture of each part contribute to its function.
Blood pressure and analysis Recording of Blood pressure and analysis of B/P reading Explain how blood pressure is measured using an aneroid sphygmomanometer? An aneroid sphygmomanometer is an instrument for measuring blood pressure in the arteries, especially one consisting of a pressure gauge and a rubber cuff that wraps around the upper arm and inflates to constrict the arteries. (www.answers.com) The principle of measurement consists in recording not the blood pressure directly in the artery but the arterial counter pressure by squeezing the artery on which the pressure is measured. The doctor uses a cuff, which will be gradually filled with air to press the artery below. The doctor/ nurse listens to, using his stethoscope, to the noise emitted by blood at the time of its passage in the artery.
Initially it would rise in an attempt to compensate and hold the blood pressure up, but after awhile the body would tire and his heart rate would fall. With his blood pressure low he would not be getting proper circulation to his brain and this would lead to disorientation. 4. It would be a very poor idea. The alcohol in the beer is a diuretic and would make him urinate more than typical.
The first factor when diagnosing Don with emphysema would be the shortness of breath. A person with emphysema normally experiences episodes of decreased airflow. This is due to the over-inflated alveoli that are not exchanging gases when a person breathes, due to little or no movement of gases out of the alveoli. The increased BP and respiratory rate show in the test that Dr. Murphy ordered show that Don has two big symptoms that could conclude he has emphysema. With this knowledge Dr. Murphy could easily notice that Don had underlying emphysema.
This allows blood to circulate more easily without putting more strain on your heart. This can also be beneficial during exercise reducing the risk of shortness of breath. Fourth is Synthroid® or levothyroxine sodium. This medication is used to treat hypothyroid and is prescribed to over 70 million people. Hypothyroidism is a condition when your thyroid is not working 100%.
Louis P Gangarosa et al said iontophoresis of lidocaine drug can provide deeply analgesic effects with shorter time span. The study was showing result of lidocaine hydrochloride decreasing pain. Pain was decreased due to lidocaine drug penetrate more deeply Penetration of lidocaine ion through stratum corneum . Stratum corneum is most resistance layer of the skin iontophoresis lidocaine transfer through this layer Kalbitz et al 1996. Lidocaine ion transfer all layers of tissue through active electrode including ligaments and tendon Massimiliano Nino et al 2010.
Central nervous system disturbances may be noted with decreased cardiac output. •Observe for chest pain or discomfort; note location, radiation, severity, quality, duration, associated manifestations such as nausea, and precipitating and relieving factors. Chest pain/discomfort is generally indicative of an inadequate blood supply to the heart, which can compromise cardiac output. Clients with heart failure can continue to have chest pain with angina or can re-infarct. •If chest pain is present, have client lie down, monitor cardiac rhythm, give oxygen, run a strip, medicate for pain, and notify the physician.
Doctors who lack proper training or those who have impairment problems tend to believe that their patients are honest about issues concerning prescriptions. These may include certain issues such as losing prescriptions, or early refills. This, however, only happens when the doctor fails to identify a drug abuse problem in the patient. Another ethical dilemma in the same field occurs when doctors do not disclose full patient history in the medical file of the patient. This may cause other doctors to prescribe the wrong drug thus putting the life of the patient at risk, either due to possible
