Is a weak acid which is well absorbed in the stomach. As thromboplastin is not part of the blood, this blood clotting pathway is known as the extrinsic pathway. They are the most common ADRs but are associated with lower morbidity and mortality. Their mechanism of action is to increase the affinity of the GABA for the GABA-A receptor. a) Gold compounds b) Methotrexate c) Sulfasalazine d) Chloroquine 10 What is the mode of action of DMARDs? These medicines work by influencing the ribosome in the cell to stop making the viral proteins. The 38 general slowing of the gut may affect the absorption of other drugs. The Human Rights Act (1998) describes the need for nursing care to be given with respect and to be proportionate to the needs of the patient. It is thought that this class of drug interferes with COX2 but has the disadvantage of interfering with COX1. Methotrexate Methotrexate works on DNA, the genetic material within the nucleus of a cell. Basic Pharmacology for Nurses 16th Edition by Willihnganz and Clayton Test Bank Aspirin also has a number of other side-effects which are dealt with in more detail in Chapter 5. we are still learning what the mechanism of action is. Aspirin is a weak acid drug that will readily be absorbed in the stomach due to its acid environment. âMicrovascular diseaseâ refers to damage to smaller vessels, resulting in eye problems (retinopathy) and kidney damage (nephropathy). Two important categories are absent seizures which used to be called petit mal and tonic clonic seizures which used to be called grand mal. The basic principles of pharmacology, pharmacokinetic processes including absorption, distribution, As a result there is a large range of medicines in this group that can be prescribed for infections. The drug should be stopped and an alternative found where necessary. Remember to always report any signs or symptoms to the nurse in charge. Distribution à à à à Drugs are distributed into major body fluids (e.g. Even though Mrs Simpson could, in theory, buy paracetamol over the counter, you should bear the following in mind: Her ability to go shopping. a) They make the nociceptors more sensitive b) They directly stimulate the nociceptors c) They stimulate the release of bradykinin d) They only act on receptors in the central nervous system 2 Local anaesthetic agents work by a) Opening potassium channels b) Opening sodium channels c) Blocking potassium channels d) Blocking sodium channels 3 Why are some local anaesthetics given with adrenaline? Some of them also sensitize the receptors that are responsible for us feeling the sensation of pain (this is further discussed in Chapter 3 on analgesics). Molecules which bind to these receptors are called ligands. A new class of drugs is currently 55 Chapter 4 Antimicrobials are six inhibitors currently available in the United Kingdom). Our partners will collect data and use cookies for ad personalization and measurement. Target sites for drug binding. Macrophages are a type of bacteria-engulfing cell or phagocyte which are protective in function. and Phillips, N. (2006) Nursing Calculations, 7th edn. Middleton, C. (2003) Non-steroidal anti-inflammatory drugs: indications for use. The drug is extremely specific for this enzyme, so enhancing the inhibitory effects of GABA in humans. This results in a fall in all blood cell elements. When developing a teaching plan, nurses should allocate time to discuss with patients what they would like to know about their medication. 107 Chapter 7 Drugs used in chronic conditions Box 7.2 The two types of diabetes 108 Type I Type II Other names Juvenile onset diabetes Insulin-dependent diabetes (IDDM) Maturity onset diabetes Non-insulin-dependent diabetes (NIDDM) Description Little or no insulin produced by the pancreas; insulin is required to sustain life, therefore the individual requires daily insulin in order to survive Pancreas doesnât make enough insulin, or body doesnât use insulin correctly; therefore the individual needs to control their intake of carbohydrates. The main problem with this drug is its serious toxic effects. Pyrazinamide is wellabsorbed orally and becomes widely distributed in the tissues and fluids of the body. By blocking the action of DNA polymerase, the drug Chapter 4 Antimicrobials prevents the host cell making copies of the virus. As the bodyâs blood sugar is constantly elevated, the body develops a 79 Chapter 5 Anti-inflammatory drugs secondary diabetic condition. Calculations 1 Pethidine 100mg in 2ml is available to you. Other genes may be involved in influencing how a person perceives and responds to a certain kind of event or stressor, which may lead to depression in certain people but not in others. Involved in the bodyâs response to stress. Second, it may inhibit ârepetitive firingâ of neurones. Physico-chemical factors relate to the chemical make-up of the drug in relation to human physiological function: Solubility: how soluble the drug is in body fluids. Earlier we discussed tissue injury (see p. 28) and how prostaglandin release is implicated in this. Its duration of action is approximately six hours and therefore is less likely to cause hypoclycaemia. These medications are also available as dry powders, administered by inhalation. Clayton, B.D. Most short-acting beta 2 agonists are available as aerosols to inhale by mouth several times per day. This comes in the form of a drug called Naloxone which has great Chapter 3 attraction to all three opioid receptors. The causation of hypertension is most likely to be due to a number of interrelated factors which may be genetic or environmental. They were first implicated as having a role in depression in the 1960s. Mechanism of action of antibiotics. Hirudin This anticoagulant is a naturally occurring protein found in the salivary glands of medicinal leeches. Side-effects are generally mild: nausea, abdominal pain and headaches are commonplace. Any invasion or abnormal growth pattern of micro-organisms which causes our body to defend itself is an infection. Both models rely on what psychologists call the locus of control. It reduces both substances in the body but because 94 Clinical tip Many hospitals have advice for patients who receive Warfarin, explaining the therapy. It is also possible that the drug may be carcinogenic and it is therefore only used to fight life- or sight-threatening disease. Chapter 2 Adverse drug reactions and interactions Many of these medications have few alternatives that are as effective for some patients, which can mean that reactions may be inevitable. London: Hodder Arnold. thromboxane: implicated in making platelets more sticky. basic pharmacology for nurses 15th edition Sep 25, 2020 Posted By Edgar Wallace Publishing TEXT ID 642ac630 Online PDF Ebook Epub Library basic pharmacology for nurses 18th edition known for its impeccably accurate and up to date drug content this best selling text consistently underscores medication safety Bacteria are classified into a number of types based on how they appear through a microscope â Chapter 4 Antimicrobials Interference with the synthesis of essential bacterial cell components e.g. à Two types: insulin dependent and non-insulin dependent. These sideeffects are linked to prostaglandin inhibition. Clayton, B.D. Recently, a person suffering from leukaemia was receiving regular chemotherapy by IV infusion. Bendroflumethiazide works by stopping the body from selectively reabsorbing sodium. Intracranial bleeding in the baby may occur during delivery. Finally, amoebae move by extending parts of their cytoplasm into false limbs called pseudopodia. Concordance involves the sharing of knowledge, understanding and beliefs by both parties. Valproate may increase this refractory period or time by a small amount. Further exsanguination is possible by applying a large rubber bandage called an esmachs bandage. This type of ADR should always be recorded in the patientâs notes and be easily visible to any future prescriber. Auranofin also has other advantages as well as the way it is administered. Therefore, crushing tablets or separating capsules can alter the delivery system. C: chronic effects. Painful stimuli are received by the nociceptors and then transmitted by two different types of nerve fibres: A delta fibres and C fibres. Finally, other chemical messengers summon these phagocytic cells from the area of damage by the process of chemotaxis. Some drugs are not fully absorbed from the stomach if they are taken at the same time as an antacid preparation. Serotonin is increased at the synapse. Calcium antagonists are well absorbed by the gastrointestinal system and are given in tablet form. (2000) Clinical Pharmacology for Nurses, 16th edn. (2006) Basic Pharmacology for Nurses, 14th edn. In order for the bacteria to survive through replication this information needs to be copied. How many tablets will you give? It is given intravenously and usually is only indicated in high risk patients undergoing certain invasive procedures, for example, coronary angioplasty. Thinning of the skin The patient must also be educated regarding the risks of suddenly stopping their medication. Brenner, G.M. Two distinct areas are implicated: Psychological factors These are known to play a part in the development of many types of depression and can be categorized as follows: Childhood and developmental experiences that are seen as negative, such as: abuse, be it physical, mental or sexual; separation from one or both parents with maternal separation being particularly traumatic; breakdown of the relationship between parents and/or problems with the parent/child relationship. The main method of renal elimination is by active glomerular filtration. If we block the bodyâs ability to respond to the release of histamine then it would seem reasonable to suggest that the inflammatory response, in terms of vasodilation and increased permeability of vessels, will no longer take place. As a result their use is usually confined to treating side-effects of drugs given as neuroleptic agents (e.g. Flucystosine acts on the fungal DNA. The doctor could then prescribe the drugs enterally, therefore making administration lawful. As with Fluconazole, the side-effects when taken orally are mild with gastrointestinal disturbance, itching, low blood sodium (hyponatraemia) and other blood disorders being reported. Severe acute asthma (known as status asthmaticus) is not reversed very easily and, as a result, continues to be fatal and requires prompt treatment. the substantia gelatinosa) that Melzack and Wall (1965) proposed a gate-controlled entry for the sensation of pain into the central nervous system. Therefore it is important to ask the patient a series of questions about their past medical history before administration of this drug. This is due to action on a reported third COX pathway. à Consent is an important area of drug administration. à Drug action can also be affected by drug affinity. Increased sympathetic activity which activates stress hormones and an excessive dietary salt intake, possibly associated with a low potassium intake, are also implicated in the pathogenesis of this disease. Using supporting literature from the internet, what conditions must the nurse have satisfied to become a prescriber? The chapter is only introductory and is not intended as comprehensive coverage of all chronic conditions and their pharmaceutical management. Any infection must be treated early with antibiotics and an increased dose of steroid to compensate for the bodyâs natural response. a) International normalized ratio b) International notifiable ratio c) Internal negative report d) Integrated notice of randomization 8 Aspirin has an effect on the balance of which two substances? g 125 Chapter 7 Drugs used in chronic conditions f à Drugs are often given in combination therapy. Calcium is another example of a body chemical affected by glucocorticoid activity, as glucocorticoids tend to lower the rate of absorption by the gastrointestinal tract and increase its loss via the kidneys. You should warn patients that on certain drugs weight gain can be a significant problem. How much do you draw up? Describe the information given to a patient who is taking anticoagulant therapy, in particular Warfarin. Pain is a difficult concept to define. Patients at risk of developing oral candidiasis are those being treated with antibiotics and steroids and it is important that when applying nystatin orally to these individuals you are aware whether they have dentures. c) The following day after surgery? Earlier in this chapter we described the chemicals that cause inflammation. Infection quite often arises after a person has inhaled the fungi. (2007) Pharmacology and Medicines Management for Nurses, 4th edn. This causes a âdampening downâ effect for all neuronal activity. (2006) Pharmacology, 2nd edn. The extrinsic pathway is therefore triggered by events such as physical injury to the blood vessels. The ADR should always be recorded in the patientâs notes. The aetiology of depression is still unclear. à Poor management of ADRs can lead to poor adherence to medication regimes. Prostaglandins, especially the prostaglandin E series are responsible for making the nociceptors more sensitive. a gram) to a larger unit (e.g. This is largely controlled by: route of administration; rate of absorption; manner of distribution. Antacids such as Gaviscon 16 The main message is to always follow any special instructions given with oral medicines to ensure optimal absorption. In secondary hypertension the elevated blood pressure is caused by renal or endocrine disease. Generally, these drugs have a short period of action. Yeasts, known as cryptococcus neoformans can lead to serious meningitis or endocarditis. Basingstoke: Palgrave Macmillan. You suspect this has been caused by the antibiotics. It is a broad spectrum antibiotic which can be used against gram positive and gram negative organisms. Education allows patients to develop a knowledge and understanding of their disease and its management, and is sometimes equivalent to that of the health professional involved in their care. The internet and its many search facilities have dramatically opened up the amount of information available, however there can be problems with accessing the internet. Trounce, J. SSRIs have less side-effects and are safer in overdose compared to other antidepressants. a) The patient may forget to take the medicine b) It may increase the lithium level in the blood c) It will make the lithium inactive d) Ibuprofen also affects mood 42 g Chapter 3 Local anaesthetics and analgesics f 7 One of the mechanisms of opiates is thought to be a) Blockage of calcium channels b) Opening of calcium channels c) Blockage of sodium channels d) Opening of sodium channels 8 Which of the following is not a receptor for morphine? Penicillamine This drug was discovered in the 1950s as being in the urine of patients who had taken penicillin. February 6, 2017. How much do you need to give 12 units? These drugs are well distributed throughout the body and some do not cross the blood-brain barrier and, therefore, cause less sedation than those that do. This side-effect is rare but can occur in low doses in some individuals. For the first six months of treatment the patient will need a regular blood test (e.g. Understand at a basic level the term âaffinityâ. Nevirapine is 100 per cent bioavailable compared to efavirenz which is between 50 and 60 per cent bioavailable. Assuaging Elizabethâs concerns. Clinical tip It is important as a nurse to recognize that babies, particularly those less than 6 months old may not have a mature liver and therefore drugs are given with great caution. Side-effects are relatively minor but obviously troublesome if you are the one taking the medication. These cells have the ability to reproduce through sexual and asexual means. However, stocks of drugs on the wards and patientsâ individual drug boxes carry both names. The concept of affinity Drugs have what is termed an affinity for their receptors, or chemical targets. g 144 Chapter 8 Drugs used in mental health f à They may help people with mild anxiety to function in certain situations. The cell body houses the nucleus and therefore is the metabolic centre. Coben, D. and Atere-Roberts, E. (2005) Calculations for Nursing and Healthcare, 2nd edn. They include: Figure 8.3 SSRI action uptake of 5-HT from the synapse after it has been released. It takes several days to achieve its effects. The major cation in our discussion here is sodium. It is important that nurses understand the implications attached to choosing routes of administration of drugs based on their absorption. Log in to Reply. If patients are prescribed the drug, they should be advised to get a baseline eye test and repeat this on a six-monthly to yearly basis. check all previous medication). Do not forget that some patients are very knowledgeable about their condition and the medicines that they take. Histamine has an action on a number of different receptors. Antibiotics can be described as being bacteriostatic or bacteriacidal. As with heparin, the most obvious side-effect is bleeding. Drugs can also lead to exaggerated anticoagulant effects if given in conjunction with Warfarin. Oral hygiene and assessment of the mouth is an important aspect of nursing. For example, you need to know some background on the patient even before correctly identifying them. Mosby Elsevier. More serious sideeffects include a drop in white cells in the body (leucopenia). adrenaline receptors). Basically, this drug limits the amount of acid secretion by cells in the stomach wall. This species of protozoa is responsible for diseases such as sleeping sickness and certain forms of vaginitis and urethritis. When absorbed through the stomach after oral administration, the drugs enter blood vessels which go directly to the liver. Complex partial seizures usually originate from the temporal lobe and are preceded by what is called an aura or warning. Press Release WHO/42, 28 September. After being absorbed, cephalosporins are widely distributed in the tissues of the body. Jarvis, J., Burden, A. and Burden, M.L. These cause disease only when our resistance is lowered through other diseases or when our natural barriers have been affected by disease or trauma. The correct dose of aspirin naturally depends on the condition being treated. Deborah Robertson is Senior Lecturer in Adult Nursing in the Faculty of Health and Social Care at University of Chester, UK. Box 5.1 Common side-effects of steroids Secondary hypertension Euphoria Hirsutism Moon-shaped face Masked infection Osteoporosis Adrenal atrophy Clinical tip Peptic ulceration Normal doses of steroids in healthy individuals do not usually pose much of a risk. Nurse prescribers must have an identified prescribing role within their area of practice, be at least three years post-registration and have successfully completed an approved programme of training. (2000) Clinical Pharmacology for Nurses, 16th edn. In chronic inflammation, the cells that are found at the site of injury differ from those for acute inflammation. Most are also available as solutions that can be used with a special apparatus called a nebulizer. Common drug reactions occur in just over 1 per cent of patients taking the medication. Sometimes this results in diarrhoea which can lead to a lack of vitamin K absorption. However, what we do know is that they interfere with a fungal enzyme called P450. Prostaglandins contribute to our natural balance (homeostasis) and have important roles to play within the body. In 2008 the NMC set out its latest guidance for the administration of medicines. Formation of a platelet plug begins with exposure to collagen and elastin fibres. For use against trichomoniasis it is usually given as a single oral dose. Newell, K. and Hume, S. (2006) Choosing the right inhaler for patients with asthma, Nursing Standard, 21: 46â8. Using the BNF is imperative in drug administration Nursesâ basic arithmetic has been criticized for drug errors. Side-effects can also include neutropenia (low level of a type of white blood cell called a neutrophil in the bloodstream). Decrease in nausea. The patient may also need to have blood tests from time to time to make sure that the dose of valproate is enough and not too much or too little for them. However, side-effects do still occur and are divided into local and general. G gamma-aminobutyric acid (GABA): neurotransmitter associated with a dampening effect on brain activity. Doses of drugs can be increased at 6 months and slowly raised to adult doses for many drugs by the age of 12, when organ maturity is achieved. A typical condition caused by infection with dermatophytes (dermatomycoses) is tinea (ringworm). Outline the mode of action of selective serotonin re-uptake inhibitors (SSRIs). If this breaks off, it becomes what is known as an embolus. Patients who have a narrowing of their renal artery (renal artery stenosis) will develop renal failure if treated with this group of drugs as their bodies depend on a fully functioning renin angiotensin cycle. Captopril is a powerful hypotensive drug and therefore patients usually start on a low dose. When the amoeba infects the person, the wall of the large intestine is damaged, so causing ulceration and bleeding. This is called the first pass effect. Some drugs are what are termed pro-drugs â that is the drug itself is pharmacologically inactive until it is metabolized by the liver to its active form. The doctor now wishes to give her a âshort burstâ of high dose steroid to bridge her transition onto methotrexate. Simonson, T., Aarbakke, J., Kay, I., Coleman, I., Sinnott, P. and Lyssa, R. (2006) Illustrated Pharmacology for Nurses. Two types of lymphocyte will have been created by the body: âTâ lymphocytes which naturally attack any foreign antigens, and âBâ lymphocytes which produce the immunoglobulins mentioned earlier which neutralize any toxins produced by the invading bacteria. Another type of antidepressant, selective serotonin re-uptake inhibitors (SSRIs) can appropriately be used in chronic anxiety of longer than four weeksâ duration. When cells are damaged, they release a substance called arachidonic acid. The Regulations lay out five schedules defining the drugs included (see Table 10.1). However, it is possible by blood testing to confirm within a few weeks of infection whether the person has Chapter 4 Antimicrobials acquired the virus. Define the condition rheumatoid arthritis. Large amounts of lymphocytes are found in the area of chronic inflammation. Even though the drug is less likely to cause bleeding, it is contraindicated in pregnancy, uncontrolled hypertension, haemorrhagic cerebrovascular disease and active internal bleeding. P phantom limb pain: the sensation of pain that is still reported from a patient after the removal of a limb/body part. Nair, M. (2007) Diabetes management: nursing management of the person with diabetes mellitus â part 2, British Journal of Nursing, 16(4): 232â5. New York: Churchill Livingstone. The idea of prescribing other than by a doctor was first suggested in 1986 following a review of community nursing services, leading to a report by Baroness Julia Cumberlege. bradykinin: powerful pain-producing substance. She has juvenile chronic arthritis which has been treated with ibuprofen. We will now focus on each of these drug classes. (2006) Respiratory nursing: understanding difficult-to-control asthma, Nursing Times, 102(36): 44â5. Lignocaine and pilocaine are again frequently used and the result is that the patient will feel pressure Chapter 3 but no pain. Their posture becomes affected and they begin to bend forward and walk in small, shuffling steps. also have a significant impact. Sulpiride is a dopamine and 5-HT blocker and is effective in the treatment of schizophrenia. In other words, it produces its own DNA by using a viral enzyme and then embeds the viral DNA into the hostâs DNA. The local anaesthetic in this case is put directly into the cerebrospinal fluid. Glucagon is a hormone which works in an opposite way to insulin and raises the blood glucose level by promoting the breakdown of stored glucose in the liver and muscles. However, its exact mode of action is still not known. adrenaline: hormone produced by adrenal medulla to prepare the body for fight or flight. They can do this as the cell contains packages of an enzyme that breaks down the bacterial walls. Therefore, the concentration of these drugs will rise if given together with protease inhibitors. The chapter will give you an appreciation of pharmacodynamics and pharmacokinetics. This loss of efficacy is probably due to the unrelenting course of the disease. However, using the central nervous system actions of antihistamines can be problematic. Biological factors Biological factors have become a major focus for research into depression and antidepressant drugs. à Checking for allergies is also important. à Being able to read clearly the name of the medicine on the prescription chart and on the packaging is important. HIV is the result of the invasion of a particular lymphocyte called a helper T cell (T4 cells). Lowey, A. This is fortunately rare but can be fatal. The Publisher and Author make no representation, express or implied, with regard to the accuracy of the information contained in this book, and cannot accept any legal responsibility or liability for any errors or omissions which may be made. Treatment for epilepsy is aimed at producing a life free of seizures. Insulin lispro is a special form of human insulin which works more rapidly than actrapid but for a shorter period of time. Abciximab interferes with this process. withdrawal effects are possible with some drugs). Excretion Relatively few drugs have a dramatic effect on drug excretion. Aspirin is a weak acid; therefore, it is absorbed better in an acid environment such as the stomach, although the small intestine absorbs the greatest amount of the drug due to its large surface area. Due to these major problems it is important that gentamycin is kept within a therapeutic range in the plasma. 3 How many milligrams are in 1.2g? Adrenergic side-effects such as hypotension, arrhythmia. Explain the mode of action of non-steroidal anti-inflammatory agents. a) 5 b) 3 c) 2 d) 1 4 What does PGD stand for? One of the most common drugs in this group is gentamycin. They do not cause hypoglycaemia as a side-effect when used on their own but may do so if combined with insulin or a sulfonurea. The drug is metabolized in the liver by a group of enzymes called cytochrome P450. It is the major inhibitory neurotransmitter in the brain and central nervous system. The patient will also be given an anticoagulant card to remind them of the dose they are taking or to be prescribed in the future by either the anticoagulant clinic or the GP. Coben, D. and Atere-Roberts, E. (2005) Calculations for Nursing and Healthcare, 2nd edn. Downie, G., Mackenzie, J. and Williams, A. New medicines are being introduced daily and it is the nurseâs responsibility to gain knowledge regarding the medicines they are dealing with. These drugs have a wider therapeutic index and are therefore less toxic than barbiturates. Isoniazid affects enzymes in the liver that break down certain anti-convulsant drugs. If the dose is increased it can lead to dizziness, ringing in the ears (tinnitus), headaches and blurred vision. 9 You have a syringe of enoxaparin containing 150 mg per ml. Therefore, in opioid overdose, an antidote is necessary. Outline why it is important to recognize the correct route of administration when giving a drug. Higher affinity means that even small amounts of the drug will bind preferentially. In acute asthma the main reason for obstruction of the airways is bronchoconstriction caused by a substance called histamine. The nurse should provide the patient with medication leaflets to promote recall of details given to them during any medication teaching. 9 A client is prescribed 4g of trifluoperazine orally and 5g in 5ml liquid forte is available. The legislation specifies that each PGD must contain the following information (see the Medicines and Healthcare Products Regulatory Agency at www.mhra.gov.uk/Howweregulate/ Medicines): the name of the business to which the direction applies; the date the direction comes into force and the date it expires; a description of the medicine(s) to which the direction applies; class of health professional who may supply or administer the medicine; signature of a doctor or dentist, as appropriate, and a pharmacist; signature by an appropriate organisation; the clinical condition or situation to which the direction applies; a description of those patients excluded from treatment under the direction; a description of the circumstances in which further advice should be sought from a doctor (or dentist, as appropriate) and arrangements for referral; details of appropriate dosage and maximum total dosage, quantity, pharmaceutical form and strength, route and frequency of administration, and minimum or maximum period over which the medicine should be administered; relevant warnings, including potential adverse reactions; details of any necessary follow-up action and the circumstances; a statement of the records to be kept for audit purposes. The drug is well absorbed from the gastrointestinal tract and therefore can be given orally. It is a pro-drug activated by the liver when it first passes through. Acute inflammation An example of this would be an insect bite. The opposite is an external locus of control where the person believes that they have little or no control and that their life circumstances have been dictated by factors external to them. Once they have achieved this they can direct the manufacture of more viruses. She is also on Warfarin for her atrial fibrillation. a) Using a spacer and altering the inhaler technique b) Altering the inhaler technique and taking antifungal lozenges c) Rinsing the mouth and altering their inhaler technique d) Using a spacer and rinsing the mouth after taking the medication 3 Glipizide belongs to which family of hypoglycaemics?
