3.Discuss the importance of identifying a patients’ use of alternative, nutritional, and complementary therapies in the delivery of pharmacological care.
4.To maximize beneficial responses and minimize harm, discuss how drug therapy must be adjusted to account for sources of individual variation.
Answer:
Pharmacodynamics and Pharmacokinetic Principles during the Nursing Administration of Medications
Pharmacodynamics refers to the study of how medicine or drugs act on a living organism while pharmacokinetic influences the route of medication administration that is, the frequency and amount of every dose. Absorption refers to how a drug gets into the blood circulation, distribution refers to the dispersion of a drug all through the body, metabolism refers to changing of the drug from patent element to metabolites, and excretion refers to the removal of a drug from the body (Schatzberg, Cole, DeBattista, 2010). One of the similarities between excretion and metabolism is that they are jointly subsumed as elimination of a drug. Notably, all the principles involve the administration of drugs; however, the difference is that each carries out different function in the administration of drug.
Nursing’s Role and Legal Responsibilities for Drug Administration
The nurses literally play the role of lifeguarding in drug administration. They provide the final chance for the health care team to identify as well as correct errors in the prescription and distribution of medication or drugs. The nurses always administer the medication. They are the final link a safeguard against error and medication administration (Schatzberg, Cole, DeBattista, 2010). The nurses also have legal responsibilities to ensure the right patient is administered for a drug, right medication and right dose are provided for a patient, right route of medication is followed, right time of medication is adhered to, and the drug administered to a patient responds as desired.
The Importance of Identification of Patients’ Use of Complementary Therapies, Alternative, and Nutritional Delivering Pharmacological Care
It is important to note that identification of a patients’ use of alternative, nutritional, and complementary therapies in the delivery of pharmacological care helps in eradication the side effects of a drug (Schwartz, 2010). It ensures that health care providers prove an evidenced-based and comprehensive care which encourages the significance of compassion and caring focuses on healing, and encourages patients to take part in decision-making about choices of care and therapeutic options.
How Drug Therapy Should Be Adjusted to Account for Sources of Personal Variation
To minimize harm and maximize beneficial responses base adjustments on body surface is necessary. It is important for the nurses to take into account how lean or fat a patient is and how body fats impacts distribution (Schwartz, 2010). The pharmacists should also measure the drug concentration and interpret the results before administration to patients to minimize harm and maximize beneficial responses.
