Medication Education Components There are basic components that should be included when teaching about any new medication purchase calcitriol 0.25 mcg fast delivery medications during pregnancy chart. These are (1) medication name buy cheap calcitriol 0.25 mcg line treatment plan for ptsd, (2) purpose buy discount calcitriol 0.25mcg medicine, (3) dosing regimen generic calcitriol 0.25mcg mastercard treatment for vertigo, (4) administration, (5) adverse effects, (6) any special storage needs, (7) associated laboratory testing, (8) food or drug interactions, and (9) duration of therapy. Unfortunately, when taking a medication history, we still have patients who refer to medications by their understood purpose (e. This creates a challenge for the provider who needs to select appropriate therapy. Both the generic name and the brand (trade) name should be given, or at least included in written handouts. Knowing both empowers the patient to catch medication errors in the event that two different providers prescribe the same generic drug under different brand names. Purpose Patients are more likely to participate in activities when they know those activities produce positive outcomes. Knowing the reason the medication is prescribed propels the patient to follow through with the medication plan because the patient is aware that this action helps to achieve the therapeutic goal. Dosing The dosing regimen needs to be reviewed with the patient even though it is written on the prescription label. Doing this ensures that the patient understands how to take the medication and provides an opportunity for the patient to ask questions. For example, “four times a day” may be interpreted in various ways by different people. Can the medication be taken every 4 hours for four doses, or does it need to be spaced out evenly to every 6 hours? Does “once a day” mean that it can be taken at any time, or it is better to take the medication in the morning or evening hours? This is also a good time to explain why drugs should be taken exactly as prescribed. Administration A common patient concern is whether medication should be taken with or without food. Patients also need to be informed of common administration needs that many of us take for granted. For example, suspensions should be shaken (or rolled, if shaking causes foaming) to equally disperse ingredients before administration. Patients need to see how these are administered and should be able to repeat a demonstration before leaving with a prescription. Although that concern is understandable, and the consequences may well be true, patients have a right to know of potential harms that may result from therapy. Therefore providers are ethically obligated to divulge adverse effects and other risks. That said, often the approach used in discussing these can make a difference in how patients view them. You probably know patients who worry about taking drugs when the product labeling (i. Patients may not know that, for most drugs, most adverse effects occur in less than 1% to 2% of those taking the drug. Most patients are unaware that the long list of adverse effects represents all effects reported during clinical trials, regardless of whether a direct association to the drug is known. When discussing adverse effects, focus on the adverse effects that are common and avoid undue attention on rare and unanticipated effects. If complex effects such as liver injury or pancytopenia may occur, teach patients the signs and symptoms to report. Let patients know that many adverse effects – most commonly nausea and sedation – are usually temporary and go away with continued medication use. Patients are often willing to endure short term adverse effects for long term health improvement. For example, some antibiotic suspensions, insulins, and rectal suppositories need to be refrigerated. Medications such as sublingual nitroglycerin and dabigatran [Pradaxa] need to be stored in their original container to prevent drug breakdown and loss of potency. Laboratory Testing Laboratory testing is sometimes necessary to determine whether a medication remains safe and effective. For example, liver enzymes may need to be checked periodically for drugs that can cause liver damage. Serum drug levels may need to be checked when maintaining therapeutic levels is challenging. They also need to know why the monitoring is necessary because those who understand the purpose are more likely to adhere to testing schedules. Rather than telling them that a blood test is needed, let them know the type of blood test, e. Patients need to know, in advance, how often testing is needed so they can make plans. In some practices, testing takes place at locations other than the primary clinic. Patients who are unfamiliar with the area need directions to the testing site and where to go after arrival. If they understand the need for testing, they are more likely to adhere to testing schedules. If exercise testing is needed, patients should be told to bring comfortable shoes. It is important to let patients know of anything they need to do prior to arrival. Food or Drug Interactions Many medications interact with certain foods or other drugs (including alcohol and other recreational drugs). Patients need to know of any potential interactions and the consequence of those interactions. They also need to know if the problem with interactions can be solved by taking substances further apart or whether they need to avoid an interacting food or drug for the duration of therapy. For example, antacids may be taken with most drugs as long as administration is separated by 2 hours; however, patients taking metronidazole must avoid alcohol for the duration of therapy. Duration of Therapy It is important to let the patient know if medication therapy is being prescribed for a short time (e. Failure to recognize the need for prolonged therapy is a common reason patients stop medications prematurely when a prescription runs out. Written Instructions Medication information is notoriously easy to forget, especially for patients taking numerous medications. For those who are unable to read due to literacy or vision problems, video or audio instructions can be used.
It is safe provided circulation is maintained (no fear of hepatic encephalopathy purchase 0.25mcg calcitriol with visa treatment zamrud, thought previously) buy cheap calcitriol 0.25 mcg line medicine qd. Plasma expander such as dextran (8 g/L of ascitic fuid removed) or haemaccel (125 mL/L of ascitic fuid removed) may be used buy 0.25mcg calcitriol mastercard symptoms pinched nerve neck. It relieves resistant ascites 0.25mcg calcitriol sale administering medications 8th edition, also frequency of paracentesis and diuretic doses are reduced. A: It means bacterial infection in peritoneum in a patient with cirrhosis of liver with ascites in the absence of any apparently primary source of infection. Source of infection cannot be determined usually (so it is called spontaneous), suspected in any patient with ascites who presents with fever with deterioration of general condition. Other organisms are Klebsiella, Haemophilus, Enterococcus, other enteric Gram-negative organisms, rarely pneumococcus and streptococcus. Clinical features: Patient with cirrhosis and ascites may present with sudden abdominal pain, fever, increasing ascites, not responding to diuretic. This can be prevented by norfoxacin 400 mg daily or ciprofoxacin 500 mg once or twice daily or cotrimoxazole (1 double- strength tablet, 5 days/week). In any patient with acute variceal bleeding, risk of bacterial peritonitis may be reduced by giving injection ceftriaxone 1 g daily or oral norfoxacin. In a1-antitrypsin defciency: Serum a1-antitrypsin (which may be associated with liver disease and pulmonary emphysema, particularly in smokers). A: Hepatorenal syndrome is a form of functional renal failure without renal pathology in a patient with advanced cirrhosis or acute liver failure. It occurs in 10% cases and is of two types: • Type 1: characterized by progressive oliguria with rapid rise of serum creatinine. No proteinuria, urine sodium excretion is low (,10 mmol/day) and urine/plasma osmolality ratio is. Mechanism of hepatorenal syndrome: Initially there is vasodilatation possibly due to nitric oxide, which causes hypotension. Also there is high plasma renin, aldosterone, nor-epinephrine and vaso- pressin, causes vasoconstriction of renal vessels and increases pre-glomerular vascular resistance. A: Hepatopulmonary syndrome is defned as hypoxaemia occurring in a patient with advanced liver disease. It is due to intrapulmonary vascular dilatation with no evidence of primary pulmonary disease. But with more severe disease, the patient is dyspnoeic on standing with characteristic reduction of arterial oxygen saturation. Transthoracic echo shows intrapulmonary shunting (probably due to excess nitric oxide produc- tion). A: It is defned as pulmonary hypertension and cirrhosis of the liver with portal hypertension. There is increased pulmonary vascular resistance with normal pulmonary artery wedge pressure, found in 1 to 2% cases of cirrhosis. It is caused by vasoconstriction and obliteration of pulmonary artery due to circulating vasoconstrictors, particularly endothelin-1. Lower end of oesophagus: • Portal: Oesophageal tributaries of left gastric vein communicate with • Systemic: Oesophageal tributaries of azygos veins. Lower end of rectum and anal canal: • Portal: superior rectal vein communicates with • Systemic: middle and inferior rectal veins. Paraumbilical: (called Caput Medusae) • Paraumbilical vein (portal) communicates with systemic veins in superfcial epigastric vein. Bare area of liver (intra-hepatic): • Portal: Portal radicles of liver communicates with • Systemic: diaphragmatic veins by a number of small veins, called accessory portal system of Sappey. Retroperitoneal site: • Portal: splenic and colic veins communicate with • Systemic: left renal veins and other tributaries of inferior vena cava by small veins called veins of Retzius. These are found along the area of superior vena cava, common in neck, face, chest and dorsum of hand, above the nipple lines, cause of which is unknown. Blanches on pressure with rapid flling on release of pressure, may pulsate if large. Physiological: • Rarely present in normal people (2%), 1 to 2 in number, common in children. Spider angioma in Spider angioma in Spider angioma in Spider angioma in shoulder hand nose face Mechanism of spider angioma: • Due to hyperdynamic circulation. Differential diagnoses of spider angioma: • Purpura (spontaneous bleeding into skin and mucous membrane, does not blanch on pressure, there is progressive colour change). It is caused by elevated venous pressure, does not blanch on pressure and blood fow is from periphery to the centre of lesion (opposite to spider angioma). Because circulating levels of oestrogen increase in both cirrhosis and pregnancy, oestrogen is thought to be the cause for the increased vascularity. Transverse white lines may also be seen in hypoalbuminaemia associated with liver cirrhosis. It is elicited by asking the patient to stretch out arms in front, separate the fngers, dorsifexion of wrist with fxed forearm by the examiner’s hand. Features of fapping tremor: • It is absent at rest, produced by intentional movement, maximum at sustained posture. It is due to methyl mercaptan, exhaled in breath, derived from amino acid methionine, which is not deaminated by the diseased liver. Methyl mercaptan is of intestinal origin (reduced by defaecation or use of antibiotics). Presence of foetor hepaticus indicates severe hepatocellular failure with collateral circulation. Actual cause is unknown, probably due to upregulation of opioid receptors and increased levels of endogenous opioids. Less or not helpful in parenchymal liver disease, as vitamin K is not used or less used by the diseased liver. It is reversible, does not cause marked pathological change in brain and may cause cerebral oedema in advanced stage. In diseased liver, these are not metabolized and enter into the brain through portosystemic shunt. Nitrogenous substances are: • Ammonia (due to breakdown of protein by intestinal bacteria). A: As follows: • Precipitating factors should be avoided (drugs, constipation, electrolyte imbalance, bleeding). Rifaximin 550 mg three times daily orally (not absorbed, acts by reducing bacterial content of bowel). A: Lactulose is a non-absorbable disaccharide, reaches the colon intact, metabolized by colonic bacte- ria to lactic acid. A: It is a clinical syndrome of encephalopathy characterized by confusion, stupor and coma, resulting from sudden severe impairment of hepatic function, occurring within 8 weeks of onset in the absence of pre-existing liver disease. A: As follows: • Two commonest causes are viral hepatitis (commonly B and E, rarely A) and paracetamol toxicity. Features of cerebral oedema due to raised intracranial pressure, such as: • Hyperventilation. A: Constructional apraxia means inability to perform a known act in the absence of any motor or sensory disturbance.
A: As follows: • Ataxia is usually truncal safe 0.25 mcg calcitriol symptoms vitamin d deficiency, causes diffculty in standing and sitting unsupported with broad based gait cheap calcitriol 0.25 mcg 4 medications at walmart. A: Alcohol cheap calcitriol 0.25mcg medications names, which causes atrophy of anterior part of vermis (sparing the upper limb) generic calcitriol 0.25 mcg with amex medicine kit. A: When only truncal ataxia is present, there is abnormal speech and heel–toe walking is positive. Vascular (cerebellar haemorrhage or infarction, arteriovenous malformation, brainstem vascular lesion). Neoplasm (haemangioblastoma, medulloblastoma, astrocytoma, secondary deposit, compression by acoustic neuroma). A: It is concerned with the control of voluntary movements, maintenance of posture and balance. A: Carcinoma of ovary, uterus, breast, small-cell carcinoma of lung, Hodgkin’s lymphoma etc. Cerebellar lesions are usually bilateral (unilateral lesion is against paraneoplastic cerebellar lesion). Two antibodies are recognized for different malignancies: • Anti-Yo (anti-Purkinje cell antibody): Related to carcinoma of ovary, uterus and breast. A: As follows: • Gait ataxia: inability to do tandem walking (heel to toe walking)—lesion in anterior lobe (palaeocerebellum). Talk to the patient: • Speech—slow initiation, husky, slurred, indistinct, lacking intonation, low volume and monotonous (or mutism). Glabellar tap (Myerson’s sign): Positive (tap the forehead above the bridge of nose repeatedly). In normal person, blinking will stop after 3 to 5 blinks, but in parkinsonism, the patient continues to blink. Look at the tremor (see below): Present at rest, tremor disappears or reduces with activity or holding something. Tests for hypokinesia: • Ask the patient to do fastening of button (patient is unable or can do slowly). Ask the patient to stand and see the position (there is fexed and stooped attitude). Gait: Ask to walk and to turn quickly (there is diffculty in starting to walk, called freezing, paucity of movement, less swinging of arms and fexed attitude, inability to turn rapidly, called fractionated turn). Once started, there is rapid, small, shuffing steps (hardly raising the foot from ground), as if trying to keep up with his own centre of gravity. A: Mention the causes according to the age: In elderly patients, the causes are: • Idiopathic or paralytic agitans (common cause). Tremor is absent in 1/3rd cases at presentation, also may be absent throughout its course in • some cases. A: 2 types: • Lead pipe: Resistance is uniform throughout the passive movement (better seen in elbow and knee). A: In hysterical rigidity, muscle tone increases more and more with increasing manoeuvre of the affected limb. A: Dyskinesia is the diffculty in initiating motor activity or poverty or slowing of movement (called bradykinesia). In Parkinsonism, there is delay or slowness in initiating or slowness of movement (bradykinesia). Also, progressive slowing, smaller in amplitude and speed of repetitive movements, such as opening and closing the hand or fnger tapping. Stimulus Tremor is present with voluntary movement, Tremor is present at rest rarely at rest (called action tremor) 2. Course Stable and slowly progressive Progressive Q:Describe the typical gait in Parkinsonism. A: It is characterized by: • Rapid small shuffing step (festination) with stooping forward and narrow base in order to avoid falling, hardly raises the foot from the ground and feet may scrap the ground. A: As follows (these tests should not be done at the bedside): • Propulsion: If the patient is pushed from behind, he is unable to stop himself and may fall forward. Other diseases (called atypical Parkinsonian syndrome): • Shy–Drager syndrome (Multiple system atrophy). A: It is a syndrome consisting of tremor, rigidity, bradykinesia and loss of postural refexes. A: Parkinson’s disease (paralysis agitans) is the primary or idiopathic Parkinsonism. It is a neurode- generative disorder due to involvement of basal ganglia, characterized by slowness of movement, rigidity, tremor and loss of postural refex. A: It characterized by features of Parkinsonism associated with other degenerative disease of cerebellum and pyramidal system, such as progressive supranuclear palsy (Steele–Richardson–Olszewski syn- drome), olivopontocerebellar degeneration, nigrostriatal degeneration, primary autonomic failure (Shy–Drager syndrome, also known as multiple system atrophy). A: In idiopathic Parkinsonism, there is progressive degeneration of pigmented dopaminergic neurons of substantia nigra and formation of eosinophilic cytoplasmic inclusions in neurons (Lewy bodies, which contains a synuclein and ubiquitin). Hence, there is defciency of dopamine (and melanin) with relative increase in cholinergic transmission (imbalance between dopamine and acetylcholine). There may be slowness of thought and memory retrieval (bradyphrenia) and subtle personality changes. Drugs: Phenothiazines (chlorpromazine, prochlorperazine), butyrophenones (haloperidol), metoclopramide, tetrabenazine, methyldopa, sodium valproate, lithium. Parkinsonian plus (when associated with features or pathology of other disease): • Shy–Drager syndrome (Multiple system atrophy). Normal pressure hydrocephalus (triad of urinary incontinence, gait apraxia and dementia). Atherosclerotic Parkinsonism (characterized by stepwise progressive broad based gait and pyramidal signs). In patient,50 years, screening for Wilson’s disease: • Serum ceruloplasmin (low). Q:How to differentiate between post-encephalitic Parkinsonism and paralytic agitans? Complaints Mainly rigidity, also impaired higher Mainly tremor functions, excess salivation (autonomic features), little or no tremor 5. Eye signs: Present Absent • Oculogyric crisis Present Absent • Ophthalmoplegia Abnormal (dilated, irregular) No abnormality • Pupil 7. Neurological features: • Present • Absent • Dystonia, dementia, chorea, • Usually lead pipe (due to absence of • Usually cogwheel hemiparesis tremor) • Normal • Rigidity • Brisk • Flexor • Tendon refexes • Extensor • Plantar response 8. Combination of levodopa and dopa-decarboxylase inhibitor is the treatment of choice. Available combinations are levodopa and carbidopa (110 or 275 mg), levodopa and benserazide (62. Drugs should be started with lowest possible dose and gradually increased as needed. Tremor may be controlled by anticholinergic drugs (such as trihexyphenidyl, benztropine, orphenadrine, benzhexol, biperiden). Less used because of side effects (dry mouth, blurred vision, constipation, urinary retention). Other measures: • Cognitive impairment and psychiatric symptoms may be helped by rivastigmine.
