Answers xvii Conversion of dosages to mL/hour Sometimes it may be necessary to convert a dose (mg/min) to an infusion rate (mL/hour) purchase 250mg keftab otc. Conversion of mL/hour back to a dose 48 You have dopexamine 50mg in 50mL and the rate at which the pump is running is 21 mL/hour generic keftab 250mg. There have been numerous articles highlighting the poor performance of various healthcare professionals discount keftab 500mg free shipping. The vast majority of calculations are likely to be relatively straightforward and you will probably not need to perform any complex calculation very often generic 250 mg keftab visa. It is difficult to explain why people find maths difficult purchase keftab 750 mg otc, but the best way to overcome this is to try to make maths easy to understand by going back to first principles. Maths is just another language that tells us how we measure and estimate, and these are the two key words. It is vital, however, that any person performing dose calculations using any method, formula or calculator can understand and explain how the final dose is actually arrived at through the calculation. Working from first principles and using basic arithmetical skills allows you to have a ‘sense of number’ and in doing so reduces the risk of making mistakes. However, this is not to say that calculators should not be used – calculators can increase accuracy and can be helpful for complex calculations. The main problem with using a calculator or a formula is the belief that it is infallible and that the answer it gives is right and can be taken to be true without a second thought. This infallibility is, to some extent, true, but it certainly does not apply to the user; the adage ‘rubbish in equals rubbish out’ certainly applies. An article that appeared in the Nursing Standard in May 2008 also highlighted the fact that using formulae relies solely on arithmetic and gives answers that are devoid of meaning and context. The article mentions that skill is required to: extract the correct numbers from the clinical situation; place them correctly in the formula; perform the arithmetic; and translate the answer back to the clinical context to find the meaning of the number and thence the action to be taken. How can you be certain that the answer you get is correct if you have no ‘sense of number’? You have no means of knowing whether the numbers have been entered correctly – you may have entered them the wrong way round. For example, if when calculating 60 per cent of 2 you enter: 100 60 × instead of 60 100 You would get an answer of 3. Another advantage of working from first principles is that you can put your answer back into the correct clinical context. You may have entered the numbers correctly into your formula and calculator and arrived at the correct answer of 1. For example: 1 You have: 200mg in 10mL From this, you can easily work out the following equivalents: 100mg in 5mL (by halving) 50mg in 2. If your answer means that you would need six ampoules of an injection for your calculated dose, then common sense should dictate that this is not normal practice (see later: ‘Checking your answer – does it seem reasonable? Using it will enable you to work from first principles and have a ‘sense of number’. The rule works by proportion: what you do to one side of an equation, do the same to the other side. In whatever the type of calculation you are doing, it is always best to make what you’ve got equal to one and then multiply by what you want – hence the name. Make everything you know (the left- hand side or column L) equal to 1 by dividing by 12: 12 apples =1 apple 12 As we have done this to one side of the equation (column L), we must do the same to the other side (column R): £. So multiply 1 apple (column L) by 5 and don’t forget, we have to do the same to the other side of the equation (right-hand side or column R): Checking you answer: does it seem reasonable? Working from first principles ensures that the correct units are used and that there is no confusion as to what the answer actually means. In reality, we would have completed the calculation in three steps: 12 apples cost £2. As stated before, it is good practice to have a rough idea of the answer first, so you can check your final calculated answer. Your estimate can be a single value or, more usually, a range in which your answer should fall. If the answer you get is outside this range, then your answer is wrong and you should re-check your calculations. The following guide may be useful in helping you to decide whether your answer is reasonable or not.

Changing public attitudes towards drink-driving discount keftab 250mg line, the adoption of legal measures and enhanced enforcement have certainly contributed to the decrease of road deaths attributed to alcohol order 500mg keftab overnight delivery. Thanks to these projects keftab 125 mg, it is possible to study and compare the opinions and attitudes and reported behaviour of the road users in different countries keftab 375 mg otc. The subjects covered a range of subjects order keftab 125 mg free shipping, including the attitudes towards unsafe traffic behaviour, self-declared (unsafe) behaviour in traffic, and support for road safety policy measures – overall over 222 variables. A Belgian polling agency coordinated the field work to guarantee a uniform sampling procedure and methodology. The results of the 2015 survey are published in a Main report and six thematic reports:  Speeding  Driving under the influence of alcohol and drugs  Distraction and fatigue  Seat belt and child restraint systems  Subjective safety and risk perception  Enforcement and support for road safety policy measures There are also 17 country fact sheets in which the main results per country are compared with an European average. An overview of the data collection method and the sample per country can be found in the Main report. The present thematic report on driving under influence of alcohol and drugs embraces the following questions: Where you live, how acceptable would most other people say it is for a driver to….? In order to assess if the answers were significantly different from one group to another (for example men vs. Part two (further analyses) consists of inferential statistics (logistic regression models describing the relationship between several explanatory variables such as gender, age, level of education, driving frequency, attitudes towards impaired driving, support of measures, acceptability of impaired driving, risk perception and the binary dependent variable ‘presence or absence of self-reported drink-driving, respectively self-reported drug-driving’). Descriptive analysis The first part of this chapter (descriptive analysis) focuses on the attitudes and opinions towards drink-driving, resp. The acceptability of such behaviours and the opinion about the risks related to these behaviours are analysed in detail. In the second part of this chapter, the analyses will concentrate on self-reported driving under the influence of an impairing substance, including medication. Acceptability of impaired driving (other people and personally) Two similar questions were asked in order to find out the level of acceptability of the behaviour ‘driving under the influence of an impairing substance’:  ‘Where you live, how acceptable would most other people say it is for a driver to drive under the influence of.? A large majority of the respondents (about 97%) were of the opinion that driving under the influence of an impairing substance is unacceptable, rather unacceptable or were neutral (scores 1 to 3) and only 3. Most of the respondents seem to believe that other people somewhat find these behaviours more acceptable than they do: the percentages of persons answering that ‘others’ find it acceptable to drive under the influence of an impairing substance ranged between 5. The level of acceptability of the three behaviours ‘drink-driving’, ‘drug-driving’ and ‘drink-drug-driving’ is very close. Drink-driving seems to be a little bit more acceptable than driving under the influence of both alcohol and drugs. In all countries, the same phenomenon can be observed: the respondents consider that other people somewhat more readily accept drink-driving or drug-driving than they do themselves. The ‘perceived social acceptability rates’ on this matter are the lowest in the same two countries where the level of personal acceptability was the smallest (1. The countries with the lowest and highest acceptability (perceived social as well as personal) rates for ‘drink-driving’ also have the lowest and highest acceptability rates for drink-drug-driving. An exception is the country with the second highest personal acceptability rate: Poland in place of France. The acceptability rate of drug-driving by country reveals an interesting fact: the country with the maximum respondents indicating that it is acceptable to start driving 1 hour after using drugs (other than medication) is Finland, whereas it has one of the lowest acceptability rate for drink-driving (see also point 4 Discussion. The country with the second highest personal acceptability rate of drug- driving is Italy (4. The ‘perceived social acceptability rates’ on this matter are the highest in Greece (13. The fact that the respondents consider that other people more readily accept drink-driving or drug- driving than they themselves do, can also be observed in the gender or age groups. The next two figures focus on the personal acceptability of drink-driving, drug-driving, and drink-drug-driving. For the three topics, the level of personal acceptability is clearly smaller among women than among men (Figure 2). Notes: (1) % of acceptability: scores 4 and 5 on a 5-point scale from 1 ‘unacceptable’ to 5 ‘acceptable’. The level of acceptability of driving under the influence of an impairing substance clearly depends on the age group (Figure 3).

The dose should be calculated so as to correspond to 10-16 mg/kg/dose of lumefantrine; 10 mg/kg/day of amodiaquine; 20 mg/kg/day of piperaquine). Clinical condition of young children can deteriorate rapidly; it may be preferable to start parenteral treatment straight away (see next page). Antimalarial treatment During pregnancy, see Antimalarial treatment in pregnant women. The dose is expressed in quinine salt: – Loading dose: 20 mg/kg to be administered over 4 hours, then, keep the vein open with an infusion of 5% glucose over 4 hours; then – Maintenance dose: 8 hours after the start of the loading dose, 10 mg/kg every 8 hours (alternate quinine over 4 hours and 5% glucose over 4 hours). For children under 20 kg, administer each dose of quinine in a volume of 10 ml/kg of glucose. Do not administer a loading dose to patients who have received oral quinine, mefloquine within the previous 24 hours: start with maintenance dose. Symptomatic treatment and management of complications Hydration Maintain adequate hydration. Adjust the volume according to clinical condition in order to avoid dehydration or fluid overload (risk of pulmonary oedema). Severe anaemia – Blood transfusion is indicated: • In children with Hb < 4 g/dl (or between 4 and 6 g/dl with signs of decompensation ). Hypoglycaemia may recur: maintain regular sugar intake (5% glucose, milk, according to circumstances) and continue to monitor for several hours. Notes: – In an unconscious or prostrated patient, in case of emergency or when venous access is unavailable or awaited, use granulated sugar by the sublingual route to correct hypoglycaemia. Coma Check/ensure the airway is clear, measure blood glucose level and assess level of consciousness (Blantyre or Glasgow coma scale). In the event of hypoglycaemia or if blood glucose level cannot be measured, administer glucose. If the patient does not respond to administration of glucose, or if hypoglycaemia is not detected: – Exclude meningitis (lumbar puncture) or proceed directly to administration of an antibiotic (see Meningitis, Chapter 7). Oliguria and acute renal failure Look first for dehydration (Appendix 2), especially due to inadequate fluid intake or excessive fluid losses (high fever, vomiting, diarrhoea). Restrict fluids to 1 litre/day (30 ml/kg/day in children), plus additional volume equal to urine output. As with other methods for treating hypoglycaemia, maintain regular sugar intake, and monitor. Clinical features Inoculation may be followed by an immediate local reaction (trypanosomal chancre). Signs include intermittent fever, joint pain, lymphadenopathy (firm, mobile, painless lymph nodes, mainly cervical), hepatosplenomegaly and skin signs (facial oedema, pruritus). Signs of the haemolymphatic stage recede or disappear and varying neurological signs progressively develop: sensory disturbances (deep hyperaesthesia), psychiatric disorders (apathy or agitation), disturbance of the sleep cycle (with daytime somnolence alternating with insomnia at night), impaired motor functions (paralysis, seizures, tics) and neuroendocrine disorders (amenorrhoea, impotence). Patients often die of myocarditis in 3 to 6 months without having developed signs of the meningo- encephalitic stage. Patients receiving pentamidine can be treated as outpatients but those receiving suramin, eflornithine (with or without nifurtimox) or melarsoprol should be hospitalised. In the event of an anaphylactic reaction after the test dose, the patients must not be given suramin again. It is nonetheless recommended not to postpone the trypanocidal treatment for more than 10 days. Treatment in pregnant women All trypanocides are potentially toxic for the mother and the foetus (risk of miscarriage, malformation, etc. Prevention and control – Individual protection against tsetse fly bites: long sleeves and trousers, repellents, keeping away from risk areas (e. Transmission by contaminated blood transfusion and transplacental transmission are also possible. The disease is only found on the American continent in the area between the south of Mexico and the south of Argentina. Chronic phase – Follows a long latent period after the acute phase: cardiac lesions (arrhythmia and conduction disorders, cardiomyopathy, heart failure, chest pain, thromboembolism) and gastrointestinal lesions (megaoesophagus and megacolon). Laboratory Acute phase – Thin or thick film: detection of the parasite in blood or lymph nodes.
