Drug administration

  1. 1. DRUG ADMINISTRATIONBYNelson Munthali Dip/RN
  2. 2. OBJECTIVES Define drug administration. Mention types of drug administration. Explain the indications for each route of drug administration. Advantages and disadvantages of each route. List the five rights to ensure proper drug administration. Discuss important information concerning medication to assess from the patient on admission and before medication administration.
  3. 3. DEFINITION This is the process of giving out medication to the patient in order to treat or prevent disease or complication. A drug is any substance that alters physiologic function with the potential for affecting health. A medication is a drug administered for its therapeutic effects. Thus all drugs are medications but not
  4. 4. ROUTES OF DRUGADMINISTRATION Oral. Parenteral- intramuscular, intradermal, intravenous and subcutaneous. Topical – skin, otic , vagina, rectal, nasal and ophthalmic.
  5. 5. COMPONENTS OF A DRUGORDER Medication nameThe name of the medication can be written in most settings using the genetic or trade name. The name should be clear all the time. Medication dosageThis includes the frequency and strength of the of the dose e.g. Metronidazole 500mg every 8 hours. Route of administrationMost medications can be given by several routes e.g. orally (PO), intravenously (IV),and intramuscularly (IM).
  6. 6. COMPONENTS OF A DRUGORDER SignatureA signature of the prescribing officer must appear below the written order.
  7. 7. THE PATIENTS RIGHTS To be informed of the drugs name, purpose, action and any possible adverse effects. To refuse any medication. To have complete information about the experimental use of drug and to refuse or consent to its use. To receive labelled medications safely. Not to be given unnecessary
  8. 8. MEDICATION ASSESSMENT To administer medication safely to any patient, it is important to collect information during the initial assessment. This is baseline data but it should be on going nursing assessment to determine drug effectiveness and promptly identification of side effects. This will also assist in individualized patient teaching to help ensure patient compliance with pharmacologic therapy.
  9. 9. INFORMATION COLLECTED ONADMISSION. Important information to elicit from the patient during the initial interview includes a medication history , allergies, medical history and pregnancy lactation status.
  10. 10. ASSESSMENT BEFOREMEDICATION ADMINISTATION Medication record.This allows the nurse to see which medication has been used most recently and whether it is time for the medication to be administered . This prevents incidences whereby a drug is administered at the wrong time. Diet and fluid orders.A patient may have fluids and food withheld in preparation for surgery or a
  11. 11. Cont…But if patient is on medication which cannot be stopped abruptly, like antihypertensives , they have to take them with small sips of water.If a diabetic patient is on NPO the physician should be contacted because of the need to adjust or withhold the medication. Patients blood glucose levels are checked regularly and if
  12. 12. Cont… Physical assessment.-Check for the ability to of the patient by giving the patient a sip of water to swallow aswallow nd if he does not cough or chock then he can take medication orally.-Gastrointestinal motility should be assessed too because a dysfuntional gastrointestinal system affects drug absorption.
  13. 13. -Check if the patient has enough muscle mass to tolerate the medication because lean muscles can result into poor absorption of medication as they are injected in the subcutaneous muscles. -check for adequate venous access and the temperature, redness, swelling and pain at the insertion site.- Vital signs should be checked for medication requiring this e.g. digitalis which require a heart rate of not less than 60 beats per minute because they slow the heart beat.
  14. 14. CONT…Assessment of knowledge and compliance.This ensures that the patient takes the medication with knowledge of the purpose and side effects of the medication.
  15. 15. FIVE RIGHTS IN MEDICATIONADMINISTRATION.Each time a medication is administered it is important to make sure that the right patient , is given the right medication in the right dose by the right route at the right time.1. Right patientmedication has to be given to the patient for whom it is intended. The patient should tell you their name and you check on the treatment chart.
  16. 16. Cont…3. Right dosage.Giving the dose that was ordered for the individual patient.4. Right route.Medication is given by the ordered route is safe and appropriate for the individual patient.5. Right time..Giving the medication at the time it is
  17. 17. DOCUMENTATION This is very important because it avoids medication errors like repeatition . The time when the drug was given should be indicate against the signature. If medication was not given for some reasons it should be indicated on the chart e.g. NPO. For drugs like insulin injections the site too should be indicated. The therapeutic and side effects of the medication should be
  18. 18. ROUTES OF MEDICATIONADMINISTRATION ORAL MEDICATIONMedication that are given by mouth are designe dto be swallowed(oral route), to be held under the tongue until they dissolve (sublingual).Purpose1. Provide a safe, effective, economical route for administering medications.2. Provides a sustained drug action with
  19. 19. ASSESSMENT Review the order considering the five rights. Assess patients allergy history . Assess patient ability to take oral medications .- Level of consciousness, cooperativeness.- Presence of swallow reflex.- Symptoms of nausea and vomiting.
  20. 20. Cont….-identify any pre administration assessment of pulse, Bp, that must be done.- Check that correct medication and dosage is available at the time scheduled.EQUIPMENT Treatment charts/ kardex. Trolley.
  21. 21. PROCEDURE Wash hands to reduce transfer of microorganisms from hand to medication. Arrange medication charts next to medication trays and cups. This saves time and reduces chances of errors. Prepare medications for only one patient at a time to prevent errors during preparation.
  22. 22. Cont…. Ask patient to state their name and compare name on medication card or record with name the patient is mentioning. Complete any preadministration assessment e.g. (Bp) required by specific medication to determine if medication can be given at that time. Expain the purpose of the medication to patient, in accordance with patients
  23. 23. Cont… Dispose of soiled supplies and wash hands. Record time medication was administered and any pre- administration assessment data which were collected.
  24. 24. Examples of oral medication Paracetamol, Brufen, metronidazole etc.
  25. 25. PARENTERAL The giving of medication that are given by injection or infusion through intramuscular(IM), intradermal(ID), subcutaneous (SC) and intravenous(IV).IndicationTreatment of disease / conditions whereby the appropriate is the parenteral route.
  26. 26. ADVANTAGES ANDDISADVANTAGES Medication given through the parenteral route usually are absorbed more completely and have a faster onset of action than other routes . The risk for infection is high because the skin barrier is bypassed, if aseptic techniques are not used when preparing and administering parenteral medication. Complications may occur if parenteral medications are not given tissue site or space intended.
  27. 27. EQUIPMENT Vials – containers that hold one or two dose of medication. Medication that are in powder form come with a diluent. Ampules – thin walled glass container that hold a single dose of a liquid medication. Before it is opened all medication should be moved to the ampule base by gently tapping the top of the ampule with a finger. To open the ampule the nurse holds an alcohol pad
  28. 28. Cont… Syringes – for drawing and administration of medication part : plunger, barrel, needle and needle guard.
  29. 29. INTRADERMAL INJECTIONS Given into the dermis (the layer of tissue located underneath the skin surface). A small needle and a 1ml syringe is mostly used. The skin is cleansed using alcohol wipe. The syring is held with the level of the needle up almost parallel to the skin . Small volumes of medication are injected slowly e.g. 0.25mls or less.
  30. 30. SUBCUTANEOUS INJECTION Injections are given into the subcutaneous tissue the layer of fat located below the dermis and above tissue. Absorption is usually slow, sustained and completely. Small sized syringe and needle used.Common sites : upper arm, upper back, abdomen, buttocks and thigh.
  31. 31. INTRAMUSCULARINJECTIONS Injection are given into the muscle layer , beneath the dermis and subcutaneous tissue. Absorption is at an intermediate rate, slower than IV administration and more rapid than SC administration. A larger volume of medication is given . Site choices are influenced by the age, medication to be given , amount and
  32. 32. PROCEDURE PURPOSE Administer medication deeply into muscle tissue, without injury to the patient. Administer a medication with absorption and onset of action quicker than the oral route and that may be irritating to the subcutaneous tissues.
  33. 33. ASSESSMENT Review patients medical history, medication history and allergy status. Assess for contraindications to receiving IM injections. Assess for anxiety related to fear of injection. Review chart for documentation of previous injection sites, if it’s a patient receiving multiple injections.
  34. 34. EQUIPMENT Treatment charts/ order or kardex. Antiseptic swabs . Vials or ampule. Syringes. Gloves.
  35. 35. PROCEDURE1. Check medication order.2. Wash hands.3. Assemble needle and syringe.4. Remove needle guard.5. Vials Rotate vial between palms to disperse medication. Cleanse top of medication vial with
  36. 36. Procedure cont.. Insert needle into vial and inject the air. Injected air prevents creation of negative pressure within the vial so that medication is easily withdrawn. Invert vial and withdraw the desired volume of medication.6. Ampules Flick upper stem of the ampule with finger
  37. 37. Cont… Insert needle into ampule and withdraw required dosage of medication. Dispose of ampule in appropriate container to prevent broken glass from cutting other health care workers.7. Cover needle with guard.8. If medication is known to be irritating to subcutaneous tissues replace needle after withdrawing medication. To
  38. 38. Cont..9. Select appropriate injection site by inspecting muscle size and integrity . Consider volume of medication to be injected. Larger muscles can absorb larger volumes of medication.10. Assist patient to a comfortable position and expose only the area to be injected. Don gloves especially on non dominant hand. This promotes comfort and privacy. Maintains universal precautions if blood
  39. 39. Cont….12. Cleanse the site with antiseptic swab , wiping from center of site and rotating outwards.13. Remove needle cover.14. Expel air bubbles from syringe .15. Hold syringe between thumb and forefinger of dominant hand (like a dart).16. Spread skin at the side with non dominant hand. This facilitates needle insertion by firming skin surface and flattens tissues so needle penetrates into muscle.
  40. 40. Cont…17. Insert needle quickly at a 90 degrees angle this enables needle to reach deep muscle layer . Rapid needle insertion minimizes patient discomfort.18. Stabilize syringe barrel by grassing with non dominant hand . Aspirate slowly by pulling back the plunger with dominant hand . If no blood appears inject medication slowly. If blood appears in the syringe, remove needle and dispose of syringe and prepare new medication. Blood in a syringe indicates
  41. 41. Cont…20. Gently massage site, this stimulates local circulation and speeds drug absorption.21. Do not recap needle , dispose of equipment in proper reception to protect nurses and health care workers from accidental needle injury.22. Wash hands.23. Record medication and patient
  42. 42. INTRAVENOUS PUSHPROCEDURE1. Verify medication card against the written doctor’s prescription.2. Explain procedure to reassure patient and significant other before administration.3. Do hand hygiene before and after the procedure(use gloves especially for chemotherapeutic).4. Check patency and other reaction signs or swelling, redness, phlebitis etc
  43. 43. 6. Disinfect injection port of the diluent, vial or ampule as appropriate.7. Aspirate right amount of diluent for the drug if the drug needs to be diluted.8. Aspirate the right dose and disinfect the port of the IV administration set.9. Close the roller clamp of the IV tubing from the bottle and push IV drug aseptically and slowly or according to
  44. 44. Cont…10. Open the intravenous fluids and let it run to flush medicine given .11. Regulate rate of IV fluids infusion as prescribed.12. Reassure patient and observe for signs and symptoms of adverse drug reactions.
