II. GENERAL PRINCIPLES OF
DRUG ADMINISTRATION
& SAFETY GUIDELINES
GIVING MEDICATIONS
General Principles of Drug Administration and Safety Guidelines Giving Medications
1.Confirm client diagnosis and appropriateness of medicines
2.Identify all concurrent medicines and any potential C/I and allergies
3.Research drug compatibilities, action, purpose, route, C/I, S/E
4.Calculate dosage accurately especially for pediatric clients
5.Check for expiration date of medicines
6.Confirm client’s identity 7.Provide client teachings8.Stay with client until medicines is gone; do not
leave at bedside9.After giving medicines, leave client in position
of comfort10.Give medicines within 30 minutes of
prescribed time
General Principles of Drug Administration and Safety Guidelines Giving Medications
General Principles of Drug Administration and Safety Guidelines Giving Medications 11. To ensure safety do not give a medication
that someone else prepared12. Know the policies of your office regarding
the administration of medication.13. Give only the medication(s) that the
physician has order in writing. Do not accept verbal order.
14. Check with the physician if you have any doubt about a medication or an order.
15. Avoid conversations or other distractions while drawing up and administering medication. It is important to remain attentive during this task.
General Principles of Drug Administration and Safety Guidelines Giving Medications 16. Work in quiet, well lighted area.17. Check the label when taking the
medication from the shelf, when pouring it, and when replacing it on the shelf. This is known as the “three checks” for safe medication administration.
18. Place the order and the medication side by side to compare its accuracy.
19. Check strengths of the medication (eg. 250 mg versus 500 mg) and the routes (eg. ophthalmic, otic, topical).
20. Read labels carefully. Do not scan labels or orders.
General Principles of Drug Administration and Safety Guidelines Giving Medications 21. Check the patient’s chart for allergies to components of the medication.22. Check the medication’s expiration date.23. Be alert for color changes, precipitation, odor, or any indication that the medication’s properties have changed (especially insulin, nitroglycerin & phenytoin). 24. Measure exactly; there should be no bubbles.25. Have sharps containers as close to the area of use as possible.
General Principles of Drug Administration and Safety Guidelines Giving Medications 26. Put on gloves for all procedures that might
result in contact with blood or body fluids.27. Stay with the patient while oral medication is
being taken. Watch for any reaction and record the patient’s response.
28. Never return a medication to the container.29. Never recap, bend, or break a used
needle.30. Never give a medication poured or drawn up by
someone else.31. Never leave the medication cabinet unlocked
when not in use.32. Never give the keys of the medication cabinet
to an unauthorized person. Limit access to the medication cabinet by limiting access to the cabinet keys.
Even if you are extremely careful, you may make an error when administering a medication. It is imperative that you report the error to the physician and that intervention measures start immediately. The error and all corrective actions must be documented thoroughly on the patient’s chart. An incident report must be completed for the error and filed in the patient’s chart as verification that all possible precautions were taken for the patient.
Errors made in charting medications must be corrected using a standard procedure. If you discover a charting error, mark it with one line. Then mark the correction above the error and sign it.
THERAPEUTIC SERUM MEDICATION LEVEL

Right ClientRight DrugRight DoseRight RouteRight Time
Right DocumentationRight Drug Preparation and Administration
1. Assess oral cavity and ability to swallow medicines2. Enteric-coated medicines must not be crushed. Only scored
tablets can be broken3. Do not administer alcohol-based products like elixirs to alcohol
dependent persons4. Have patients swallow medicines except for sublingual and
buccal route. Do not allow fluids 30 minutes after giving medicines. Give iron preparation using straw to prevent teeth staining.
5. When giving medicines via NGT, do not mix with food. Give before or after meals and flush tubing with 30 ml of H2O. Check for tube patency before giving medications.
IV. GENERAL CONSIDERATIONS FOR ORAL MEDICINES
• Select appropriate needle size and syringe for ID, SQ, IM ROUTES• Use tuberculin syringe for medicines less than 1 ml• Draw up air equal to amount of medicines needed• Inject air to vial to prevent negative pressure and aid in aspirating
medicines• Ampule: place needle into ampule to draw medicines and use filter
needle to avoid glass shards• Select and rotate sites avoiding bruised or tender areas• Insert needle quickly with bevel side up. Aspirate to check for blood
except heparin. If blood is present, remove needle and start again. For giving IV medicines, blood return is desired
• Apply gentle pressure after giving injections except for heparin and Z-track.
V. GENERAL CONSIDERATIONS FOR PARENTERAL MEDICINES
a. Use 25g to 27g, ½ to 1 inch needleb. Maximum volume of 1.5 mlc. Pinch skin to form SC fold and insert at 45 degrees in thigh or arm and 90 degrees in
abdomend. Possible sites: lateral aspect of upper arm,
anterior thigh, abdomen…1 inch from umbilicus and scapular area
EXAMPLES: Heparin,
Insulin, MMR,
Enoxaparin (Lovenox)
a. Use 26g to 27g, 1" needle on a 1 ml or tuberculin syringe (vol. approximately 0.1 ml)
b. Insert needle at 10-15 angle with 1-2 mm depth with needle bevel upward
c. When wheal appears, do not massage, mark
d. Possible sites: ventral forearm, scapula, upper chest
EXAMPLES: BCG,
PPD (Purified Protein Derivative)/ Mantoux test
a. Use 18 g to 23 g, 1-2 inch needle, maximum volume is 5mlb. Stretch skin tautc. Insert at 90 degrees angle. 45 degrees for infants and childrend. Possible sites: gluteus medius (ventrogluteal and dorsogluteal, vastus lateralis (anterior thigh), rectus femoris (medial thigh) and deltoide. For Z-track: 20-22 g, 2-3 inches long with a different needle to draw medicines; draw skin laterally with non-dominant hand to ensure that medicines enter muscle; wait 10 sections before removing injection; do not massage to lock irritating substances in placeEXAMPLES: Vit.K, Hep. B, DPT, Iron dextran (Z-track)
a. Check site for complications (redness, swelling, tenderness)b. Check blood returnc. Prepare medicines according to manufacturer’s specificationsd. Prepare tubing according to requirement: micro or macro tubinge. Change tubing and dress site every 24-72 days depending on hospital policy and label appropriatelyf. Never hang solutions more than 24 hours g. Use syringe infusers and infusion pumps EXAMPLES: vancomycin (Vancocin), amphoterecin B, cisplatin (Platinol), fluorouracil (5-FU), Oxytocin, Mannitol
a. Monitor the risk for fluid overload especially in patients with respiratory, cardiac, renal and liver diseases. Elderly clients and very young clients cannot tolerate excessive fluid volumeb. Clients with CHF cannot tolerate solutions containing sodiumc. Clients with diabetes mellitus does not typically receive dextrose (glucose) solutionsd. Lactated Ringer’s Solution contain potassium and should not be given to clients with renal failure
A. INFECTION
• LOCAL: redness, swelling and drainage at site• SYSTEMIC: fever, chills, HA, tachycardia, malaise
The longer the site, the higher the riskAt risk are HIV/Aids patients and those
receiving chemotherapyAssess for the S/Sx of infection, maintain strict
asepsis in IV site care, monitor WBC, check the integrity of solutions, change tubings and dressings q 24-72 hrs, prepare to obtain blood culture from venipuncture device

• PHLEBITIS: Redness, heat and tenderness at site, sluggish IV
• THROMBOPHLEBITIS: Hard and cordlike vein Use IV cannula smaller than vein
Avoid lower extremities and areas of flexion as the site
C. INFILTRATION
• Edema, pain and coolness at the site d/t seepage of IV fluid outside vein and into the interstitial space;
• May or may not have blood return
Caused when devise dislodged or perforates vein or when vein backs up pressure d/t venospasm
Infiltrated if no backflow of blood upon lowering fluid container or after occluding the vein proximal to site and IV continues to flow
Remove infiltrated IV, elevate extremity and apply cold or warm compress based on MD’s order
D. CIRCULATORY OVERLOAD
• Increased BP, distended jugular veins, rapid breathing dyspnea, moist cough and crackles
Use infusion pump esp. for clients at risk of overload and time tape
If it occurs, KVO rate, elevate head of bed, assess for edema and inform MDIf these occurs, remove and restart in opposite extremity apply warm and moist compress; inform doctor
E. AIR EMBOLISM
• Increased BP, distended jugular veins, rapid breathing dyspnea, moist cough and crackles

Place the necessary drops near the outer canthus and away from cornea.5. If using ointment, squeeze into lower conjunctiva and move from inner to outer canthus. Do not touch tip to the eye and twist tube to break medication stream.
VI. CONSIDERATIONS IN GIVING
OPTHALMIC MEDICINES
6. Let patient blink 2-3 times7. Press on nasolacrimal glands (to prevent systemic
absortion, a perfect example is atropinr sulfate)8. Wipe excess medicines starting from inner canthus9. Droppers and ointments are for individual clients and
never shared.
VII. CONSIDERATIONS IN GIVING

4. Have client remain on side for 5-10 minutes to allow medicines to reach to reach inner ear.
VIII. CONSIDERATIONS IN GIVING
TOPICAL MEDICINES1. Cleanse area to remove old medicines using gauze with
soap and warm water2. Spread medication evenly and thinly wearing gloves if the
skin is broken3. When applying nitroglycerin ointment, take the client’s BP
5 minutes before and after application4. Wash hands after applying to prevent self-absorption5. For transderm patches, wear gloves to prevent self
absorption and place in an area with little hair. Press down edges to secure patch
