Nurse's Role and Responsibilities in Medication Administration
1. Assess the Medication: Ensure that the ordered medication is correct for the patient’s diagnosis and
condition.
2. Assess Self-Administration: Evaluate the patient’s capability to manage their own medications safely.
3. Determine Administration Timing: Decide if the medication should be given based on the patient's
condition, lab values, and specific guidelines.
4. Administer Medications Correctly: Provide medications according to established protocols and
guidelines, and monitor the patient's reaction to the medication closely.
5. Educate Patients and Families: Provide clear information about the medication's purpose, side effects,
and necessary monitoring measures to both patients and their families.
6. Do Not Delegate Medication Administration: The nurse is responsible for all aspects of medication
administration and should not delegate this duty to nursing assistive personnel.
7. Apply the Nursing Process: Incorporate the nursing process—assessment, diagnosis, planning,
implementation, and evaluation—into every medication administration instance.
8. Practice the 6 Rights: Adhere to the “Rights” of medication administration: Right Patient, Right Drug,
Right Dose, Right Route, Right Time, and Right Documentation.
Physiological Mechanisms of Medication Action
1. Absorption: The process whereby medication molecules travel from the site of administration to the
bloodstream. Key factors include:
, - Route of absorption (oral, intravenous, etc.)
- Ability of the medication to dissolve
- Blood flow to the site of administration
- Body surface area for absorption
- Lipid solubility of the drug
2. Distribution: The transport of the medication throughout the body to tissues and organs where it will
exert its therapeutic effect. Influenced by:
- Circulation (blood flow to tissues)
- Membrane permeability (ease of passage through cell membranes)
- Protein binding (capacity of the drug to bind to plasma proteins)
3. Metabolism: The biochemical alterations that drugs undergo, resulting in a less active or inactive form
that can be excreted. This process often involves enzyme activity for detoxification and breakdown.
4. Excretion: The elimination of medications from the body, which can occur through the kidneys, liver,
lungs, intestines, or exocrine glands.
Types of Medication Actions
1. Therapeutic Effects: The predicted positive physiological response resulting from medication use.
2. Adverse Effects: Undesired and often unpredictable responses that can occur with medication.
3. Side Effects: Predictable and typically unavoidable adverse reactions that occur at therapeutic doses.
4. Toxic Effects: Dangerous effects that can develop after prolonged drug use or when accumulation in
the blood occurs due to impaired metabolism or excretion.
5. Idiosyncratic Reactions: Unpredictable effects that do not typically occur in most patients.
