Ineffective movements

All activities within the laboratory must be well stractured and organized to avoid ineffective movements or actions. This ineffectiveness can be corrected with the proper layout of instruments and work areas in the laboratory and a proper laboratory activity plan. 

LAXATIVES. The nurse records file results of administration on the patient s chart. If excessive bowel movements or severe prolonged diarrhea occur or if file laxative is ineffective, the nurse notifies file primary health care provider. If a laxative is ordered for constipation, the nurse encourages a liberal fluid intake and an increase in foods high in fiber to prevent a repeat of this problem. 

During the early stage of Intoxication, activity is reduced, movements are slow and ineffective, and the subject is generally unable to offer effective resistance and tends to be relatively tractable. Once this period (a few hours) has passed, his behavior becomes increasingly unpredictable, energetic, and dangerous. 

Tourette s syndrome (TS) is a hyperkinetic movement disorder with symptoms of sudden, rapid and brief, recurrent, stereotyped motor movements or sounds (tics) and can range from mild to severe. TS is commonly treated with dopamine antagonists such as haloperidol, which may be effective but has significant adverse side effects and is ineffective in up to 30% of cases. While the etiology is not known it is proposed that, unlike PD, TS represents a disorder of excess dopamine transmission in the striatum (Shapiro et al., 1989 Wolf et al., 1996), either through dopamine excess or receptor hypersensitivity. 

A second lipothrophic factor is betaine, which is effective because the transfer of at least one of its methyl groups to homocysteine is very efficient and can replenish methionine for choline formation. In the absence of sufficient lipotrophic factors, a fatty liver develops, and there is insufficient movement of fats either ingested or synthesized in the liver to the adipose tissue. As fats enter or are synthesized in the liver, they are repackaged or packaged as VLDLs to be moved out for transport from the blood to adipose tissue. The VLDLs contain protein, triacylglycerol, cholesterol, cholesterol esters, and phospholipids, especially phosphatidylcholine (lecithin). If one has either a protein deficiency or a lipotrophic factor deficiency, the movement of triacylglycerol s from the liver to adipose is ineffective and a fatty liver can develop. Choline can be present in the diet and need not be synthesized de novo. Phospholipid synthesis has been discussed previously (Chapter 15). 

DA (3,4-dihydroxyphenylethylamine Table 10-1) is the metabolic precursor of NE and Epi it is a central neurotransmitter particularly important in the regulation of movement see Chapters 12, 18, and 20). In the periphery, DA is synthesized in epithelial cells of the proximal tubule and is thought to exert local diuretic and natriuretic effects. DA is a substrate for both MAO and COMT and thus is ineffective when administered orally. Classification of DA receptors is described in Chapters 12 and 20. 

Gut and liver catechol-O-methyltransferase Postganglionic sympathetic nerve terminals Preganglionic S3Tnpathetic nerve terminals Vascular smooth muscle cell receptors A semiconscious patient in the intensive care unit is being artificially ventilated. Random spontaneous respiratory movements are rendering the mechanical ventilation ineffective. A useful dmg to reduce the patient s ineffective spontaneous respiratory activity is (A) Baclofen Dantrolene Pancuronium Pyridostigmine Succinylcholine... 

Adams (2006) reported that the electrokineticaUy induced movement of bare nanoiron (i.e., nanoscale ZVI) was ineffective in penetrating the porous matrix under a hydraulic gradient, probably due to the nanoiron agglomerating to form particles that were too large to effectively migrate through the porous matrix.
