The six rights OF Medication Pass
D Drug
R Route
P Patient
A Amount
T Time
S Scribe/ Documentation
Helps prevent medication
errors
1. Right patient:
– identify the patient you are
going to give
the medicine
Look at the patient’s ID
band too!!!
• Is this the appropriate
drug for the
condition of the patient?
• Is this the correct drug?
2. Right Drug
Is this the right dose
based on the patients
size
and age?
Right
Dosage:
Does the patient’s condition
need the quick acting route
– or can I use the longer
acting route?
• Is the medication made to
be given by that route?
– Not all IV meds can be
given IM and vise versa
Right
Route:
Is the timing between the
dosages correct?
• Is it every 3 minutes?
• Or every 5 minutes?
• Can I give this medication
only once
Right Time:
• Documentation of what you
have done
D – Drug
A – Amount
R – Route
T – Time
Right
Scribe/Documentation
• Correct medication
• Correct concentration
• Expiration date
• Seals intact
• Color
• No precipitate (floaters)

Syringes
Types of Syringes
Syringe Tips
Luer-Lok syringe (note threaded tip)
non-Luer-Lok syringe (note the smooth graduated tip)
Prefilled Syringes
The cartridge slides into syringe barrel, turns, and locks at needle end. The plunger then screws into cartridge end
Needles
• Stainless steel
• Most disposable
• Parts
• Hub
• Cannula or shaft
• Bevel
Needles
• Characteristics
• Slant or length of bevel
• Length of the shaft
• Gauge
Elder Considerations
• Altered memory
• Decreased visual acuity
• Decrease in renal function
• Less complete and slower absorption
from the gastrointestinal tract
Elder Considerations
• Increased proportion of fat to lean body
mass
• Decreased liver function
• Decreased organ sensitivity
• Altered quality of organ responsiveness
• Decrease in manual dexterity

Things to Consider
What are the life span considerations for administering oral medications?
What are the home care considerations for administering oral medications?
Nasogastric/Gastrostomy
Tube Medication
Administration
• Check with pharmacist for a liquid form
• Check to see if medication can be
crushed
• Crush a tablet into a fine powder and
dissolve in at least 30 mL of warm
water
• Open capsules and mix the contents
with water only with the pharmacists
advice
Nasogastric/Gastrostomy
Tube Medication
Administration
• Do not administer whole or undissolved
medications
• Assess tube placement
• Aspirate stomach contents and measure
the residual volume
Nasogastric/Gastrostomy
Tube Medication
Administration• Remove the plunger from the syringe
• Connect syringe to a pinched or kinked
tube
• Put 15 - 30 mL (5 - 10 mL for children)
of water into the syringe barrel to flush
the tube
• Pour liquid or dissolved medication into
the syringe barrel and allow to flow by
gravity into the enteral tube
Nasogastric/Gastrostomy
Tube Medication
Administration
• Administer each medication separately
and flush in between
• After administration of all medications,
flush again
• If the tube is connected to suction,
disconnect the suction and keep the
tube clamped to enhance absorption
