5. Discuss the role of nitrates, beta blockers, and ACE-inhibitors in the patient with an AMI. Nitrates is used to increase collateral blood flow, redistributing blood flow toward the subendocardium; beta blockers is used to reduce heart rate, decrease sympathetic stimulation of the compromised myocardium and prevent life threatening dysrhythmias. ACE inhibitors to prevent ventricular remodeling and the development of heart failure.
Feedback: INCORRECT Another assessment should be completed before assessing for distention. C) Observe the color of the emesis. Feedback: CORRECT Since the client is vomiting, the nurse should first observe the color and appearance of the emesis for any obvious bleeding or other indications of risk to the client’s homeostasis. D) Ask about recent loss of appetite. Feedback: INCORRECT This information is not a high priority at this time.
Please review Module 5, Lesson 4, Topic 2 | | Third nerve palsy, weakness, and ataxia | | Rationale:Correct | | | Question 29 - Correct | Hypertension is usually a compensatory response in the early period of ischemic strokes, therefore, in most cases the blood pressure should not be lowered. | | | Your Answer: | True | | Rationale: Correct | | | Question 30 - Correct | Which diagnostic test is used to visualize any ischemic regions in the brain within minutes of symptom onset? | | | Your Answer: | Diffusion-weighted imaging MRI
Austin Schultz Anatomy Honors February 28, 2013 Tricuspid Regurgitation Definition – Disorder in which the heart's tricuspid valve does not close properly, thus causing blood to flow backward into the right atrium when the lower right ventricle contracts. Caused most commonly by an enlargement of the right ventricle, but may also be caused/worsened through problems with valves on the left side of the heart, pulmonary hypertension (high pressure in lung circulation), or diseases such as endocarditis, which is caused by anything that allows bacteria to enter the blood stream – such as unsanitary conditions during drug abuse. Signs & Symptoms – Include fatigue, active pulsing in neck veins, general swelling (such as that of the abdomen or the feet and ankles), weakness, etc. Diagnostic Test – When gently pressing with their hand on your chest, a health care provider may find abnormalities. A physical exam may show liver and spleen swelling as well as a pulse over your liver.
Lymphocytes main function is fight against bacterial and viral infection. Elevated immune system, it can be predisposing cause of infection or it can slow the healing process. Calcium is 8.7: according to patient ABG values it indicates patient has respiratory alkalosis, it causes increase free calcium to bind to serum albumin which can leads different problems such as tetany. There are other abnormal values such as HCO3=29meq/L indicates alkalosis, PH=7.50indicates alkalosis; PaO2 =59mm/hg indicates hypoxia; PaCO2=25mm/hg indicates alkalosis. Analysis of ABG indicates respiratory alkalosis.
1. Analyze the Hemoglobin (hgb, hb), Hematocrit (hct) and Red Blood Cell Count (RBC’s) together. There are 3 basic reasons for anemia: (1) Blood is not being made (decreased erythropoetin secondary to chronic renal failure, poor nutrition, aplastic anemia, or bone marrow suppression from chemotherapy) (2) Blood is being lost (hemorrhage or bleeding from somewhere) or (3) Blood is being destroyed (some infections cause RBC lysis, transfusion reaction, Sickle cell crisis). Nursing Diagnoses 1. For erythrocytosis (increased RBC count): Risk for injury related to increased clotting ability of blood.
This can be seen under a microscope. The actual metaplasia (reddening) can be seen using a gastroscope to view the lower esophagus. It is important for the pathologist to distinguish between goblet cells of the submucosal glands and true Barrett’s esophagus. This can be done using the histochemical stain Alcian blue pH 2.5 to distinguish true intestinal-type mucins (secretion from goblet cell of Barrett’s esophagus) from a histological mimic like that of a "pseudogoblet cell" in which abundant
Paul Henderson Biology 202 Austen Barnett 18 October 2011 Sickle Cell Anemia Sickle cell anemia is a disease that affects the body’s red blood cells. Sickle Cell Anemia has many symptoms. These symptoms include anemia, (lack of oxygen supply in blood) which makes the affected individual feel weak, cold, dizzy and irritable, it also gives the skin a paler color and may even make the skin appear as a yellowish color. The disease causes many respiratory problems as well, because of poor blood flow in the lungs. Pain is a very common symptom of sickle cell anemia; this pain can be acute or chronic, while acute pain (lasting hours or a few weeks at most) is most common, chronic pain can last multiple weeks or even months.
Therefore breast feeding was highly encouraged to decrease DVT’S or what was considered “milk leg”. Etiology: (description of the cause of the disease, what organs/tissue are affected, what happens to the normal physiology (pathophysiology)?) Deep Vein is mainly caused by a combination of the slowing of the blood and increased clotting in the blood, although there are other factors that can cause clotting such as trauma. Rudolf Virchow (1821-1902) came up with Virchow’s Triad which includes Hypercoagulability (increased clotting), Hemodynamic Changes (slowing of the blood), and Endothelial injury/dysfunction (trauma). It occurs more in males than women and in those 60 years of age and older.
