DRUG ADMINISTRATION

Legal aspects of medication administration

The Joint Commission requires that two patient identifiers (e.g., name, birthday, account number) be
checked prior to administration of any medication.

Components of a legal medication order

• Date and time

• Patient’s name

• Patient’s inpatient ID number

• Drug Name and strength of dose

• Frequency of dose

• Physician’s full signature

Nurse’s legal responsibility

• Interpret each component of the order

• Question the order by communicating with the physician if

 The nurse cannot read the order

 Any component of the order is erroneous or ambiguous

 The nurse had any doubt about the appropriateness of the order

 Any order which does to make sense, such as large number of tablets or
capsule. Or a large volume of solution for injection

Controlled Substances
⚫ All controlled substances must be stored in a locked container requiring a key or
computerized access code for entry.
⚫ An inventory record of all controlled substances used is maintained.

⚫ If any part of a dose of a controlled substance is discarded, a second nurse witnesses the
disposal and the record is signed by both nurses. (Agency policies and procedures are always
followed.)

⚫ Agency policies and procedures are followed with regard to the counting of controlled
substances at the end of a shift; any discrepancy in the count is reported immediately.

Before Administration

, Review for NCLEX-RN® - PHARMACOLOGY & PARENTERAL THERAPY
⚫ Wash your hands.
⚫ Assess the prescription and compare new medication prescriptions with the current list of
medications (reconciliation).

⚫ Ask the client whether he or she has a history of allergies.

⚫ Determine the purpose of the medication.
⚫ Assess the client for existing medical disorders in which the prescribed medication is
contraindicated (e.g., many medications are contraindicated in pregnancy and for breastfeeding
clients).
⚫ Check the client’s age (the older client and the neonate are at greater risk for toxicity than is an
adult client).
⚫ Assess the client’s vital signs and significant laboratory results (e.g., the potassium level in a
client who has been prescribed a loop diuretic).
⚫ Assess the client’s understanding of the purpose of the prescribed medication.
⚫ Identify and address concerns (e.g., social, cultural, religious) that the client has with regard to
taking the medication.
⚫ Use the appropriate resources (e.g., medication formulary, pharmacist) as necessary when
preparing the medication.




During Administration
⚫ Assess the six rights: right medication, right dose, right client, right route, right time, and right
documentation.
⚫ Assess the need for conversion or calculation of a dose when preparing medication for
administration.
⚫ Administer the medication within 30 minutes of the prescribed time.

⚫ Avoid administering medications with antacids, which affect absorption of medication. Also
avoid administering medications with grapefruit juice, which contains an enzyme that inhibits
absorption of many medications.

After Administration

, Review for NCLEX-RN® - PHARMACOLOGY & PARENTERAL THERAPY
⚫ Do not recap needles; discard needles in an appropriate container, using the safety device
provided with the syringe if one is available.

⚫ Dispose of any unused medication in accordance with agency policy: Liquid medication may be
discarded in a sink or flushed down a toilet; tablets or capsules may be flushed down the toilet.
Never discard medication in a trash container.

⚫ Document administration of the medication given at€” including its name, the dose, the date
and time, and your initials at€” immediately after giving the medication.
⚫ Monitor the client for side effects or adverse effects (e.g., allergic reaction) to the medication
and take action if adverse effects occur.
⚫ Evaluate the client for a therapeutic response to the medication.

Administering Oral Medications
⚫ Pour tablets or capsules into the medication container's cap, not your hand. Medications
prepared for unit dosage may be opened at the time of administration in the client's room.

⚫ Scored tablets (those marked to facilitate division) may be divided into halves or quarters.

⚫ Enteric-coated tablets and sustained-released capsules must not be crushed.
⚫ To pour medication accurately using a medicine cup, hold the cup at eye level, then pour to the
line designating the desired measure of medication.
⚫ Volumes of less than 5 mL are measured with the use of a syringe from which the needle has
been removed.
⚫ A calibrated dropper is used to give medicine to a child or to add a small amount of liquid to
water or juice.
⚫ Do not mix liquids with tablets or liquids with liquids in the same container.

Sublingual (under the tongue) and Buccal (between the cheek and the gum):

⚫ Instruct clients to keep the medication in place until it is absorbed.

⚫ Clients should not eat or drink while the tablet is in place.

Liquids, Suspensions, & Elixirs:

⚫ Follow directions for dilution and shaking.
⚫ When administering the medication, the base of the meniscus (lowest fluid line) is at the level of
the desired dose.

Standard precautions require the wearing of gloves when placing a tablet under a patient’s tongue.
The patient should not chew a sublingual tablet and should not drink or swallow until the tablet is
completely dissolved and absorbed.
