PHARMACOLOGICAL PERSPECTIVES
  IN NURSE’S CONTEXTUALITIES
FIVE RIGHTS IN DRUG
                 ADMINISTRATION
 RIGHT DOSE
    The nurse
       Minimizes any forms of errors
       Checks the supply – UNIT DOSE or STOCK SUPPLY
       Requires two nurses to verify the medicine being administered

 RIGHT DRUG
    The nurse
       Compares the medicine card or unit dose recording form with
        the physician’s order
       Compares the label three times
       Administers one has prepared
FIVE RIGHTS IN DRUG ADMINISTRATION

 RIGHT CLIENT
   The nurse
      Identifies the patient correctly
 RIGHT ROUTE
   Oral (Buccal or Sublingual)
   Parenteral
FIVE RIGHTS IN DRUG ADMINISTRATION

 RIGHT TIME
   The nurse must know why a medicine is ordered
    for certain times of the day & whether the time can
    be altered
      EXAMPLE: q8h and TID
      The q8h (every 8 hour) is intended for around the clock
      TID (three times a day) is given during waking hours (8 – 1 – 6)
      QID (8 – 12 – 4 – 6)
      Physician orders (stat, prn, single dose, standing)
FIVE RIGHTS IN DRUG ADMINISTRATION

 RIGHT ASSESSMENT
 RIGHT APPROACH
 RIGHT DOCUMENTATION
 RIGHT EVALUATION
 RIGHT TO CONSIDER THE CLIENT’S
  REFUSAL TO TREATMENT OR
  MEDICATION
ORAL MEDICATION

• Assessment – client’s knowledge, diet status, oral
  cavity, ability to swallow
• Enteric coated not be crushed only the scored tablet
• Time release capsule contents may be mixed with
  food
• SOLID MEDICATIONS
   – All solid medications can be placed in one container unless
     if one needs further assessment before administering
   – Unit dose in original individual package
   – Reduce chance of contamination – medicines into cap of
     container, top side down, transfer to medicine cap and
     replace lid and container
ORAL MEDICATION
• LIQUID MEDICATION
  – Shake liquid medication
    if necessary
  – Pour away from liquid
    bottle
  – Do not administer alcohol
    based products to
    alcohol dependents
  – Iron preparation with
    straw
ORAL MEDICATIONS
ORAL MEDICATIONS
• Absorption is reduced by the presence of
  food
• Dilute or dissolve irritating drugs to reduce
  gastric irritation
ORAL MEDICATIONS
• INFANTS
  – Use calibrated dropper, nipple or syringe
  – Keep infant 45 degrees
  – Not to use medicine as child’s favorite food or
    punishment
  – If using NGT, check for patency
VAGINAL INSTILLATIONS
Available as suppo, enema, foam,
jellies, creams
Individually packaged in foil wrappers
Foam, jellies, creams with inserter or
applicator; suppo with a gloved hand
Patient prefers to insert their own,
privacy needed                                 SIMS POSITION

Perineal pads provided
Aseptic technique & perineal hygiene



                                         RETRACT LABIA WITH
                                         NON DOMINANT HAND



              INSERT 2 – 3INCHES
RECTAL MEDICATION
 Differ in shape from V, thinner,
  bullet shaped, rounded

SPECIAL ASSESSMENT
 Bowel function, ability to retain supp
  or enem
 Supp from refrigerator
 Provide privacy
 Left lateral position
 Gloves or finger cot
 Lubricant
 Insert approx 2 inches, retain 10 –
  20 minutes
 If enem retain 20 – 30 min
OTIC INSTILLATIONS

         Internal ear structures

High sensitivity with extreme temperatures

    Causes vertigo (severe dizziness)
OTIC MEDICATION
SPECIAL ASSESSMENT
 Warm meds in hands
 Don gloves
 Turn to unaffected side
 Clean outer ear
 Straighten ear canal by
  pulling pinna UP & BACK
  (ADULTS), DOWN & BACK
  (CHILDREN > 3)
 Instill gtts along side w/o
  touching ear
 Remain on side 5 – 10 min
OPTHALMIC APPLICATION

Eye drops, ointment, OTC artificial tears, vasoconstrictors

                           PRINCIPLES

Cornea is supplied with pain fibers
Risk of transmitting infection
Used only for affected eye
Never allows a person to use another’s eye medication
OPTHALMIC MEDICATION
 Check solution & warm in hands
 Lie on back or sit with head turned
  to affected side
 Cleanse eyelid & eyelashes
 Have patient look up
 Assist patient in keeping eye open
  by pulling down on cheekbone with
  thumb or forefinger
 Lower conjunctiva near outer
  canthus
 OINTMENT – Squeeze into lower
  conjunctiva moving from inner to
  outer canthus, do not touch eye with
  applicator, have client blink 2-3
  times
 Wipe any excess from inner to outer
  canthus
NASAL INSTILLATION
             Altered nasal sinuses

             Spray, drops, tampons
             (Decongestant spray)

   Overuse                           Swallowed

REBOUND EFFECT                SYSTEMIC EFFECTS
NOSE DROP MEDICATION
 Have patient blow nose
 Position patient – head is tilted
  back or specific position to
  expose sinuses
 Push up on tip of nostril
 Place dropper slightly upward
  just inside the nostril not
  touching nose with applicator
 Head tilted 5 minutes
 Instruct not to blow, drops may
  produced unpleasant taste
SPECIAL CONCERNS
 (+) if patient begins to aspirates
  & coughs?
 (+) if patient is infant?
INHALANTS

          Deeper passages of respiratory tract

          Vascular alveolar – capillary network



                 EASY ABSORPTION

Designed to produce LOCAL EFFECTS but have dangerous
                  SYSTEMIC EFFECTS
             (Oxygen and general anesthetics)
METERD DOSE NEBULIZER
ORAL INHALER
METERED DOSE
 INHALER
IRRIGATION
• Medications may be used to irrigate or wash
  out body cavity & delivered thru a stream of
  solution (sterile water, NSS, antiseptic)
• Eye, ear, throat, vagina & urinary tract
• Avoid further injury to the tissue
• Prevent transmission of infection
• Maintain patient’s comfort
PARENTERAL DRUG ADMINISTRATION


ADVANTAGES                   DISADVANTAGES
• More rapid absorption      • Penetrates the first line of
  and effect                   defense, the skin
• Effects are more           • Danger of damaging
  predictable                  nerves and blood vessels
• Desirable for patients     • Pain might be present
  who are irrational,        • Possibility of abscess
  unconscious on having GI     formation
  disturbances
PARENTERAL DR ADMINISTRATION
                       UG
              SPECIAL CONSIDERATION
The size and type are determined by     Know the volume of the drug

Assess if you need assistance –
restraining or turning
