Usually requires more aggressive treatment such as reperfusion therapy. 2. What is the pathophysiology causing Mr. Canton’s cool, clammy skin and aspiratory crackles? Heart Attack, It’s the result of signs and symptoms of left side congestive heart failure. 3.
Atropine acts as an antagonist within the central nervous system, which means it acts as a blocker of specific cellular functions. What part of the autonomic nervous system does atropine block to produce its effect on Dr. Westwood? Atropine was administered in response to the bradycardia; after it was administered it brought up his blood pressure as well has his heart rate. Within the parasympathetic nervous system, Atropine blocks the muscarinic receptor which then blocks acetylcholine (Ach). Because of the blockage of Ach the muscarinic receptor antagonist can block the vagal nerve from affecting the heart, and can then increase the heart
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.
Generic name is tramadol. This is a nonopioid analgesic, but it does have weak agonist activity at mu opioid receptors. However, it causes minimal respiratory depression (although the patient should still be monitored for this). Previously was not a controlled substance, but was switched to a schedule IV in 2014. Notable side effect: seizures. Avoid use in clients with or at high risk for seizures.
Congestive Heart Failure (CHF) Congestive Heart Failure or CHF is a severe circulatory congestion due to decreased myocardial contractility, which results in the heart’s inability to pump sufficient blood to meet the body’s needs. In general, causes can be classified according to the following: a. Volume overload may cause the right ventricle to hypertrophy to compensate for added volume. b. Pressure overload usually results from an obstructive lesion, such as COA c. Decrease contractility can result from problems such as sever anemia, asphyxia, heart block and acidemia.
When the body is at rest, the heart is influenced by the parasympathetic nervous system. The parasympathetic system, originating from the medulla oblongata of the brain reaches the heart through the vagus nerve. The vagus nerve releases a chemical, acetylcholine, which causes the decrease in heart rate (Kenney, Wilmore, Costill,
This occurs when the heart becomes weakened and enlarged, and congestive heart failure follow quickly. The signs and symptoms are left and right heart failure, the autopsy signs would include central hemorrhagic necrosis in the liver. Hypertrophic is the other one which is just as our skeletal muscles hypertrophy in response to increased demand, cardiac muscle undergoes hypertrophy when placed under a high workload for a prolonged period of time. Pathologic hypertrophy is a result of disease that place increased demand on the heart, such as chronic hypertension, valvular damage, and myocardial infarction. The left ventricular hypertrophy is the most common type of hypertrophic heart disease.
This can bring about shortness of breath, leg swelling (called edema), and different issues. Furthermore, organs in your body may not get the oxygen and supplements they have to work legitimately. Heart failure is a perpetual (progressing) condition that creates after some time. It is typically created by fundamental conditions, for example, hypertension or coronary illness. These conditions harm your heart, making the heart muscle hardened or thick.
Outline the body’s response to stress (6 marks) There are two types of stress: acute and chronic stress. Acute stress (short-term stress) causes the body to respond through a process called the sympthomedullary pathways. This immediate response is achieved because of the hypothalamus’s direct link to the nervous system which causes the activation of the sympathetic nervous system (SNS). This is a branch from the autonomic nervous system. The SNS also regulates the sympathetic adrenal medullary system (SAM).
Alcohol has a wide variety street names, invented by users who want to prevent sober people from knowing that they drink. Nicknames include booze, suds, cold one, brew, and much more. Its medical name is ETOH, short for ethyl alcohol. Ingestion of alcohol causes the central nervous system to slow down, and is therefore classified as a depressant. Short term effects in low dosage include relaxation, slow reflexes and reactions, poor
