Pharmacology and Medication Administration: Key Concepts for Nurses
I. The Nurse's Role in Medication Administration
The nurse plays a critical role in ensuring safe and effective medication
administration. This encompasses several key responsibilities:
Ensuring Safe Delivery: Medications must be administered and delivered
in a safe manner, adhering to established protocols and best practices.
Verifying Order Accuracy: Nurses are responsible for being certain that
healthcare provider orders are accurate and complete before administering
any medication.
Patient Education and Understanding: It is crucial to ensure that the
patient understands the use, administration technique, and potential side
effects of all prescribed medications.
Preventing Adverse Drug Reactions: Proper administration of medications
is essential to prevent adverse drug reactions.
Important Note: While patient input is valuable, nurses must ensure prescribed
medications are administered as ordered to maintain patient safety and treatment
efficacy. Option 3 in the original question is incorrect in implying the patient's
agreement is the sole determinant for medication administration.
II. Enteral Medication Administration
Before administering drugs via the enteral route (oral, nasogastric tube, etc.), the
nurse must evaluate specific patient factors:
Swallowing Ability: The patient's ability to swallow safely is a primary
concern to prevent aspiration.
III. Managing Patient Allergies
When a patient reports a severe drug allergy, the nurse has a vital role in
preventing an allergic reaction:
, Documenting the Allergy: The allergy must be thoroughly documented in
the medical record.
Notifying Healthcare Team: The provider and the pharmacy must be
notified of the allergy and the specific type of allergic reaction.
Implementing Allergy Alert: Placing an allergy bracelet on the patient
serves as a visual reminder for all healthcare providers.
Note: While informing the patient is important, the nurse's primary responsibility
lies in direct communication and documentation within the healthcare system.
Instructing the patient to refuse medication (option 5) is not a standard nursing
intervention.
IV. Interpreting Medication Orders: STAT Orders
A "STAT" order indicates that a medication should be administered immediately.
For an order reading "Lasix 40 mg IV STAT," the nurse should administer
the medication within 5 minutes of receiving the order to achieve the rapid
therapeutic effect required.
V. Medication Administration via Nasogastric (NG) Tube
Certain medication formulations are not suitable for administration through an NG
tube:
Enteric-coated tablets: These are designed to dissolve in the intestine, not
the stomach.
Sustained-release tablets: Crushing these tablets alters the intended slow
release of the medication.
IV medications: These are formulated for intravenous administration and are
not meant for enteral routes.
Acceptable forms for NG tube administration generally include liquids and
finely crushed immediate-release tablets (when appropriate and allowed by
pharmacy).
VI. Managing Medications for NPO Patients
When a patient with diabetes is NPO (nothing by mouth) before surgery, the usual
administration of oral antidiabetic medications requires careful consideration:
