acetylcholine: chemical transmitter released by certain nerve endings. It was suggested that the dependent prescriber would be able to prescribe certain medications following initial assessment and diagnosis of the patient by the independent prescriber and the development of an agreed clinical management plan (CMP). You have a patient with swallowing difficulties. The main method of renal elimination is by active glomerular filtration. (2006) Basic Pharmacology for Nurses, 14th edn. How many tablets do you give? benzhexol, procyclidine). à Bipolar depression is treated with lithium or certain anticonvulsant drugs. This results in an increased level of serotonin in the neuronal synapse. For use in anxiety, doses tend to be low, with higher doses being reserved for use in insomnia. Stress which can be deemed as unusual or continual such as stress at work or in a relationship. Clinical tip More serious side-effects from chloroquine are ophthalmologic in nature. You should forewarn the patient of this to avoid unnecessary concern in relation to this harmless side-effect. Barber and Robertson build on your existing knowledge of anatomy and physiology to help give a holistic understanding of pharmacology and the relevant body systems. Demonstrate an understanding if what is meant by the term patient group directions. Mosby Elsevier. No need to wait for office hours or assignments to be graded to find out where you took a wrong turn. If bleeding occurs it can be treated with tranexamic acid. You can check your answers on page 176. Now suitably qualified district nurses were able to prescribe from a limited formulary for specific clinical conditions. a) NA b) DA c) BDZ d) GABA-A 4 Neuroleptic medications are used for a) Psychosis b) Neurosis c) Epilepsy d) Parkinsonâs disease 5 Lithium can be described as a) A mood enhancer b) A mood reflector c) A mood inducer d) A mood stabilizer 6 5-hydroxytryptamine is also known as a) Buscopan b) Serotonin c) Adrenaline d) 5-BC g 147 Chapter 8 Drugs used in mental health f 7 Amylobarbitone is an example of a) A barbiturate b) A benzodiazepine c) A tricyclic d) An SSRI 8 Which of the following is a benzodiazepine? Perhaps this is the reason why there is no clearly preferred medicine to treat hypertension from this group of drugs. This will be dealt with later in the chapter as a separate item. Selective toxicity is the ability of the antimicrobial to harm a pathogen (bacteria) without harming our own cells. Saquinavir is an example. You will recall that at the beginning of this chapter we discussed the importance of calcium channels opening in order to bring about the transmission of a nerve signal across a synapse. Short-acting insulins Soluble insulin produces a quick and short-lived effect. What are they? 37 Chapter 3 Local anaesthetics and analgesics Respiratory depression. Other antiviral drugs Aciclovir Figure 4.2 HIV life cycle and related medicines being developed that will be aimed at blocking the actions of integrase. Dispensing pharmacies are able to help with this if asked. The risk of this type of diabetes is also higher if it runs in the family or if the patient is overweight. Cyclo-oxygenase pathways in most pharmacological texts are denoted by the prefix COX followed by the number of the pathway (e.g. pressure increases the patientâs risk of stroke and heart attack, both of which can lead to premature death. For some patients rectal medication is unacceptable and produces anxiety regarding the route of administration. Inhaler technique is an important part of patient education. Cromoglicate This medicine is not a bronchodilator, however, if given prior to an asthmatic attack it prevents the immediate and later bronchoconstrictive reactions to inhaled allergens by stopping the release of mediators such as histamine from mast cells. It cannot be given orally. Both drugs when taken regularly reduce the frequency of ârescueâ bronchodilator intake. Where then do we start with the process of education? Medicines are designed and formulated to be absorbed according to the route of delivery; therefore, getting the route of a drug right is of paramount importance. Malden, MA: Blackwell. This information must be documented on the prescription chart and in the nursing records. He enjoys watching football and having a few pints at his local pub. Drugs used in treating asthma à à à à à à Two groups of drugs are used: bronchodilators and inhaled anti-inflammatories. We can now look at the mechanism of their action. Smith, U. Its duration of action is approximately six hours and therefore is less likely to cause hypoclycaemia. Crushing or splitting tablets. However, its exact mode of action is still not known. Azoles This group of drugs is manufactured synthetically. These types of insulins are the only ones suitable for IV injection.

Basic Pharmacology For Nurses. à Two types: insulin dependent and non-insulin dependent. These were thromboxane, which increased the stickiness, and prostacyclin, which decreased the stickiness. As with heparin, the most obvious side-effect is bleeding. Thrombosis can occur in both arteries and veins. How many should you give? The duration of drug effect relates to the time it takes for the drug to be removed from its site of action. âMicrovascular diseaseâ refers to damage to smaller vessels, resulting in eye problems (retinopathy) and kidney damage (nephropathy). Some SSRIs have associated increased anxiety until the antidepressant effect occurs, and for this reason concomitant use of a benzodiazepine for the first two or three weeks is often recommended in anxiety, with a low starting dose of SSRI building up as tolerated. Reboxitine: a noradrenaline specific re-uptake inhibitor. They may have difficulty walking (ataxia). Alteration of medicines Not only are there problems with the issue of consent, but it also appears that few nurses are aware of the pharmacological dangers to the patient and of the legal implications of tampering with drugs. It is nearly always combined with another substance that stops peripheral enzymes breaking down dopamine. Unlike static PDF Study Guide For Basic Pharmacology For Nurses 16th Edition solution manuals or printed answer keys, our experts show you how to solve each problem step-by-step. This is much preferred by the patient as it decreases the amount of oral analgesia required. This is because some side-effects can be beneficial. Describe why drug interactions occur in absorption, distribution, metabolism and excretion of drugs. Forgetfulness is a large cause of noncompliance. SSRIs have less side-effects and are safer in overdose compared to other antidepressants. However, their ability to suppress the normal inflammatory response has consequences in the masking of infections and decreasing the potential healing properties of all tissue. You should be familiar with the units in Box 1.2 as they are the most common encountered in drug calculation. Serious side-effects are not common but are important when giving information to patients. The absence of a secure or confiding relationship. 7 Your patient weighs 95kg. à Inverse agonists are drugs which can reduce the normal activity of the cell. You cannot give pure dopamine as the blood-brain barrier will not allow it to enter and it is also destroyed quickly by enzymes in the peripheral tissues. As we said earlier, motivation is the key to education. Some companies actually specialize in making drugs in liquid form. How much do you give? JAMES KEOGH, R.N. Damage to the outside of the nerves (the nerve sheaths) is also a problematic complication. if the next message follows along before the nerve has reset itself, the message canât be passed). They can do this as the cell contains packages of an enzyme that breaks down the bacterial walls. Absorption This can be a major factor in drug problems with children under the age of 12. Think of alcohol effects on liver Think about the effects of smoking on the systems of the body Consider the effects of surgery on the movement of the intestine Check the fluid balance Check the urinary output Calculations 1 2 3 4 2000 micrograms 0.6g 1200mg 1g in 10,000 is the weakest 1 2 3 4 5 6 7 8 9 10 360ml 2 tablets 2 tablets A A D C B B D B D A Chapter 2 Case study j, Marek Brodzki Your responsibilities regarding the antibiotics are: This may be a mild allergy Needs to be closely monitored No treatment necessary, although may give antihistamines Report rash to doctor The rash may become a more severe reaction Your responsibilities regarding recording the incident are: Record extent of the rash, when first noticed: is it becoming worse, how irritant is it? Karch, A.M. (2008) Focus on Nursing Pharmacology, 4th edn. This specificity is thought to occur as the drug likes a substance called ergosterol. Eventually the liver stores are exhausted and the reactive byproduct starts to damage the liver tissue itself. However, as noted above, in many developing countries cases of both disease processes continue to rise in number. The newest device on the market at the moment is the insulin jet system which can be used on the abdomen, thighs or buttocks. The virus needs this enzyme to copy its genetic code from a strand of RNA to a strand of DNA. It is derived from the natural world, being synthesized from the bark of the cinchona tree. Good consultation skills should always include the patient. In exceptional circumstances, where medication (not including controlled drugs) has been previously prescribed and the prescriber is unable to issue a new prescription, but where changes to the dose are considered necessary, the use of information technology (such as fax, text message or email) may be used but must confirm any change to the original prescription. Nigrostriatal pathway This is associated with movement disorders produced by these drugs: Parkinsonism: characterized by lack or slowness of movement, muscular rigidity and tremor; 142 dystonia: characterized by sustained muscle contractions causing twisting or repetitive movements or adoption of abnormal postures; akathisia: characterized by restlessness and unease; tardive dyskinesia: characterized by abnormal involuntary movements of the face. Product packaging can be troublesome for people with limited dexterity. Paul Barber is Senior Lecturer at the University of Chester, UK, with 33 years nursing experience.

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. Selegiline This medicine works by stopping the enzyme that breaks down dopamine in the synapses, therefore making more dopamine available. Paracetamol damages the liver if the recommended dose is not followed. This tissue is fibrous in nature and lacks the specialization of the surrounding tissue. Type A: augmented This is where the reaction is an augmentation of the drugâs pharmacology. Oxford: Oxford University Press. The longer the drug is in contact with the absorbing surface the greater the rate of absorption. Local anaesthetics and analgesics Adjuvant drugs Opioid antagonists are used in combination with non-opioid and opioid drugs to facilitate the management of pain in patients, particularly complicated and chronic pain. This in turn is utilized in two metabolic pathways, one of these being the cyclo-oxygenase pathway which creates a number of products, among them prostaglandins (we will revisit these pathways in Chapter 5). Hormonal influences Cortisol, a corticosteroid, is known as the âstress hormoneâ and has been linked to depression. The chapter examines three key areas of mental health intervention: 5 post-traumatic stress disorder (PTSD); 6 mixed anxiety and depressive disorder. Other drugs in this group e.g. Chapter 2 Adverse drug reactions and interactions Clinical tip When working in the clinical setting it is important to be thinking of the age of the person you are dealing with. Demonstrate an understanding of the links between the pharmacology of therapies used in treating asthma, diabetes, hypertension, Parkinsonâs disease and epilepsy and the care given by the health practitioner. Interferons are not just one substance but a range of proteins with different properties. Constriction allows clotting factors to come into contact with damaged vessel. Describe aspects of absorption, distribution, metabolism and excretion of a drug. Chapter 7 Diabetes Diabetes mellitus is a chronic disease of metabolism caused by either an insufficient production of insulin in the body or an insufficient effect of insulin in the peripheral tissues. Edinburgh: Churchill Livingstone Elsevier. Quinine is given to treat malaria. g 40 Chapter 3 Local anaesthetics and analgesics f Opioid analgesics à à à à à à à à à à Given for moderate to severe pain. Clinical tip Pencillin drugs are fairly free from side-effects. Long-acting insulins By mixing insulin with protamine and zinc an even longer action can be elicited. k Anil Khan is a 53-year-old man who has been diagnosed with schizophrenia since the age of 23. Once inside, it can destroy the tubercle bacillus at will. A second side-effect associated with this drug group is called the âon-off â effect. The treatment should not be too sedative as this can be as detrimental as the anxiety itself. A number of neurotransmitters are involved (e.g. This section of the chapter will briefly outline some of the most common protozoal infections. However, it is shown to reduce progression of disease in rheumatoid arthritis. Epilepsy Epilepsy is the most common chronic disabling condition of the nervous system. The daily presence of the pharmacist on the ward, monitoring prescriptions, while liaising with both the medical and nursing team, is of great importance in recognizing any such problems. These sections deliberately repeat the key texts in this field for your ease of reference, and in addition include works specific to the chapterâs topic. The effectiveness of the drug is measured by a blood test known as the prothrombin time, Anticoagulant therapy now expressed as an international normalized ratio (INR). It may be prudent therefore to consider prescribing an antibiotic that can be taken once or twice daily that can be appropriately administered around school hours. In type II diabetes the beta cells may produce small amounts of insulin but not enough to control the levels of glucose in the plasma. Some writers even suggest that pre-filled infusion bags, electronic drip counters and user-friendly drugs such as single-dosed heparin injections all contribute to the deskilling of nurses in terms of their mathematical abilities. Morphine reduces the rate at which the gastrointestinal system moves (motility). The inflammatory response is a local reaction that involves release of antibacterial substances that defend the body from attack. Relapse is common, so the need for open discussion is extremely important. (2007) Pharmacology and Medicines Management for Nurses, 4th edn. All patients should receive a copy of this. Calculations 1 A doctor has prescribed 30mg of prednisolone. Remember to always report any signs or symptoms to the nurse in charge.

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. Most people will have developed antibodies to streptococcal proteins, so often a large bolus dose is used to start therapy, followed by a maintenance infusion. This is a rare disorder which affects the liver and central nervous system, usually following an acute viral illness. Clozapine is a dibenzodiazepine neuroleptic Chapter 8 Drugs used in mental health and exerts its effect via dopamine receptors but also acts at muscarinic and 5-HT receptors. Viruses do not have the ability to reproduce and replicate themselves so they have to borrow these mechanisms from their host cell. Depression sufferers report a poor quality of life or morbidity. 159 Chapter 10 Legal and professional issues Medicines are used for their therapeutic effects and careful administration of these is paramount. These drugs improve patientsâ lives by reducing swelling and tenderness in the joints. You have available 50mg in 1ml. Coben, D. and Atere-Roberts, E.

Occasionally, they may develop a temporary itch inside the penis, a mild discharge or burning on urinating. You may also be involved in checking the stock of controlled drugs at a ward level. Roberts, J. and Williams, A. How many grams of glucose will you have in 50ml? The cell wall and plasma membrane together are called the bacterial envelope. Once the drug has been administered you will have to detail in the controlled drug register the date, time, patient name, amount of drug given, who gave the drug, who witnessed the drug being given, and finally the new stock balance. In other words, you do not raise the threshold at which the nociceptors are stimulated just because the pain is constant. Once patients leave the hospital other members of the primary care team have a duty to continue a more long-term education plan with regard to their medicines. Main classes of drugs are thiazide, diuretics, beta-adrenoreceptor antagonists, angiotensinconverting enzyme inhibitors, calcium antagonists or blockers and alpha-adrenoreceptor antagonists. However, one significant disadvantage is that the drug is not immediately reversible since it is slowly released. They bind to a specific benzodiazepine binding site (or receptor) which is situated on one of the sub-units of the GABA-A receptor. Shuttleworth, A. à Drugs do not offer a cure to the problem. We hope that our book has been one of the first stepping stones in your chosen career as a nurse. Test Bank for basic pharmacology for nurses 16th edition pdf. Explain the mode of action of a range of antibiotics used in practice settings. Karch, A.M. (2008) Focus on Nursing Pharmacology, 4th edn.

You can observe this for yourself in your patients or may even have experienced it following an epidural anaesthetic during labour. Clinical tip It is good practice to advise patients to drink plenty of water when taking aciclovir orally to avoid over-concentration of the drug (six to eight pints of water per day). London: Arnold. The less a drug binds to a plasma protein, the more efficient it is in diffusing and crossing cell membranes. Some drugs have a higher affinity for their targets than even the normal physiological molecule. They are also able to interact negatively with some foodstuffs containing tyramine and dopamine (e.g. An increase in exercise and cessation of smoking are advisable in order to reduce high blood pressure (hypertension) and high fat content in the blood (hyperlipidaemia). It can be used as an adjunct therapy with MAOIs and TCAs. Also, due to the length of time it has been used, many bacteria have developed enzyme systems to combat its effects. It is a group of disorders characterized by both physical and psychological symptoms. The Committee on Safety of Medicines (CSM) issued the following advice which can be found in the BNF (55: March 2008): Clinical tip When a patient starts taking a benzodiazepine it is very important that you warn them of the possible sedative effects and discuss the dangers of driving or operating heavy machinery. These drugs can be grouped as follows: Anticholinergics, used for motor side-effects (e.g. This applies to unionized compounds (drugs without charge), and prevents the entire dose of a drug being excreted at once. The ciprofloxacin inhibits enzymes in the liver that are normally responsible for the metabolism of theophylline. Identify a circumstance when a fibrinolytic drug would be contraindicated. An example of a short-acting drug in this class is salbutamol. It is also possible that tissue damage in one part of the body can lead to pain being perceived in another part of the body. The patient may have to be treated with antifungal lozenges. Some drugs need to be given daily, while others need to be given two, three or four times per day to maintain effective action. It can also be activated by things which are not real threats, but are perceived as real by the anxiety sufferer and can become pathological. Complex partial seizures usually originate from the temporal lobe and are preceded by what is called an aura or warning. It can become problematic in patients having bone marrow transplants and is a leading cause of death in this group of individuals. If this is present medical staff should be informed and you should document the condition of the intravenous site in the nursing care plan. Keratin is what makes up your nails and is introduced to your skin cells before you shed them. Indeed it is estimated that one species, plasmodium vivax, is capable of producing 250 million maturing protozoa from the liver cells in a 14-day period. In 2008 the NMC set out its latest guidance for the administration of medicines. Miconazole This drug can be given in a number of different ways including orally for gastrointestinal infections and as a pessary to treat vaginal candidiasis. 71 Anti-inflammatory drugs 5 Chapter contents Learning objectives Introduction Acute inflammation Chronic inflammation Non-steroidal anti-inflammatory drugs Cyclo-oxgenase pathway 2 inhibitors Aspirin Adverse effects Overdose Paracetamol Histamine Antihistamines Steroids Administration Side-effects Antirheumatoid drugs Sulfasalazine Gold compounds Penicillamine Methotrexate Choloroquine Leflunomide Case studies Key learning points Calculations Multiple choice questions Recommended further reading Learning objectives After studying this chapter you should be able to: Describe acute and chronic inflammatory processes. This is why you will find GTN being given via routes other than orally. tem becomes depleted. Clopidogrel This is a fairly new and powerful antiplatelet medicine. Noncompliance and non-adherence may be an intentional act on behalf of the patient or may be an involuntary act of which they are not even aware. The patient may also suffer more short-term side-effects from the medication, though these quite often improve over a period of time. a gram) to a larger unit (e.g. They have what is termed zero efficacy. It is vital that nurses know the normal dosing schedules for the drugs they are administering (this can easily be found in the British National Formulary â BNF) so that the correct regimen is implemented. These drugs work in the same way as penicillin in that they affect the production of the peptidoglycan wall of the bacterium. (2006) Pharmacology, 2nd edn. (2006) Basic Pharmacology for Nurses, 14th edn. All Type B and many Type A ADRs should be reported to the Medicines & Healthcare Products Regulatory Agency (MHRA) via the yellow card found in the back of the BNF or online. May be preferable in younger patients. Very rarely the drug can have severe hypersensitivity reactions. Calculations 1 A patient requires intramuscular furosimide 20mg. In this way they stop the virus from replicating. This build up of positively charged sodium is termed depolarization. It can be a protective mechanism, whereby we can respond to threats or perceived threats and prepare the body to defend itself or to flee from the danger. How much do you draw up? A third previously unknown cyclooxygenase pathway is initiated by an enzyme found in the brain and spinal cord. It also has a role to play in the kidneys, where it helps to maintain the correct pressure for the kidneys to filter water and waste products. (2005) Treatments and devices for future diabetes management, Nursing Times, 101(18): 30â2. Two major side-effects are associated with giving levodopa. The main reported side-effects include nausea and diarrhoea, loss of sexual desire and libido, some anxiety during initiation of treatment and occasionally sleep disturbances. A more passive form of drug compound movement occurs in the distal tubule of the kidney. Clinical tip While taking Warfarin, patients will have regular blood tests to establish their INR. Lifestyle changes are the first course of action in its treatment. Define the term adjuvant drug. This balancing act, therefore, has three possible end points: Resolution. In addition, nurses are governed by the legislation surrounding medicines. Thiazide diuretics These are usually the first line treatment for mild to moderate hypertension, providing there are no contraindications. Sodium aurothiomalate is administered by deep IM injection whereas auranofin is given orally. How would you put the following information into terms that Louise and her parents will understand: The mode of action of these three classes of medicine? In chronic inflammation, the cells that are found at the site of injury differ from those for acute inflammation. They were first implicated as having a role in depression in the 1960s. à Changes that took place in 2006 enabled nurses and pharmacists to take a further step and prescribe independently to an agreed clinical management plan. à Some evidence exists to suggest that antipsychotics may have a positive benefit in the treatà à à à ment of anxiety. This group of cells are implicated in the inflammatory response by releasing a range of chemicals that contribute to the contraction of bronchial smooth muscle, permeability of small blood vessels and excessive secretion of mucous. a) Anticoagulant therapy b) Morphine c) Steroid medicines d) Angiotensin converting enzyme inhibitors 10 Amphoteracin could be described as being a) A newly-developed medicine b) A synthetic antifungal agent c) A harmless medicine d) An antifungal antibiotic Recommended further reading Adler, M.W. à Prescription charts are written using the generic name. As a nurse when caring for someone who is taking lithium you should be aware of the need for monitoring the personâs fluid intake and also of the implications of sickness and diarrhoea. Antiretroviral therapy Antiviral therapy is aimed at using a combination of agents that act at different points in the replication of the virus within the human cell. It is however unclear as to how its actions relate to its therapeutic effects. If the gate was opened a person would perceive pain; if the gate was closed a person would not. It usually details why the person is taking the drug, side-effects, what an INR means and the importance of taking the medication at the same time each day. This is the thinking behind acetylcholine antagonists. Further exsanguination is possible by applying a large rubber bandage called an esmachs bandage. à Children respond differently to drugs for many reasons, most of which can be related to differences in absorption, distribution, metabolism and excretion of drugs compared with adults. The patient needs to be told to carry this card at all times and to show it to any doctor or dentist treating them. She has bedside nursing experience in medical neurology and the neuroscience ICU. This allows patients to see whether or not they have taken their medication. bradykinin: powerful pain-producing substance. Rosiglitazone may produce side-effects such as water retention. This is unique to prokaryotic cells. 63 Chapter 4 Antimicrobials Irritation and itching of the vulva are also indications of infection. Gastrointestinal symptoms and a raised temperature have also been reported. Muscarinic receptor antagonists The parasympathetic nervous system causes bronchoconstriction; therefore, if these effects on the bronchioles of the lungs were blocked dilatation would take place. Pharmacokinetics is the effect the body has on the drugs. How many ml would you give? The picture for the individual gets much worse if the amoeba breaks through the lining of the gut and invades the peritoneum, causing peritonitis. This effect should wear off after the patient has been taking the medicine for a while. They may be administered directly into joint spaces (intra-articularly) or into the lungs by means of an aerosol. London: Arnold. It reduces the manufacture of a range of clotting factors. If the cap was not placed on the mouthpiece, check the mouthpiece for dirt or other objects. The tighter the bond, the better the drug action. Alpha-glucosidase inhibitors A drug called acarbose is used from this family of medicines to treat type II diabetes. Azaspirodecanediones Buspirone is the only drug in its class available for the treatment and management of anxiety symptoms. If the therapy has to be repeated more serious sideeffects can occur such as bone marrow depression, the development of rashes and dramatic hair loss (alopecia). It is rapidly and completely absorbed when given orally and reaches its maximum effect in the plasma in two hours. Discuss this with reference to: Bacterial and viral infections.

This is important because if the drug enters the tissues rather than going into the vein it may cause local pain and irritation. It acts on fungal DNA. Alteplase à à à à Alteplase converts plasminogen to plasmin. If erythromycin is administered intravenously rather than orally, a degree of inflammation and damage to the vessel that the drug is entering (thrombophlebitis) can be expected. You only have 200mg in 5ml. May slow progression or severity of symptoms Ineveisibly inhibits monoamine oxidase B to decrease metabolism of dopamine Selegiline Add-on therapy for Parkinsonâs disease (may aid wearing off effects). Recently theophylline has also been shown to have some antiinflammatory activity, especially with regard to mast cell activity. à It is essential for the synthesis of plasma clotting factors. Most chapters contain at least two scenarios and, unlike most other books, we have included examples of some of the points that you should have been considering in analysing these scenarios. Morphine is useful in both acute and chronic types of pain. Chemicals liberated by damaged tissue (e.g. The amoeba can now be transported to other organs in the body giving rise to a high temperature and serious consequences. some medicines may cause slower growth). Some protozoa and certainly viruses need the mechanisms from our cells in order to replicate and grow. The drug is given orally as a suspension or tablet. The efficiency of a drug can be affected by the degree by which it binds to proteins within the blood plasma. The body will obviously make more GABA transaminase so the drug has to be given continuously.
