What is drug therapy? Drug therapy is the use of drugs to diagnose, prevent, or treat disease or to prevent pregnancy
Name the three most important properties of an Ideal Drug. Effectiveness, Safety, and Selectivity
What are additional properties of an Ideal Drug Reversible action, Predictability, Ease of administration, Freedom from drug interactions, Low cost, Chemical stability. Simple generic name
Four factors that determine the intensity of drug response are: Administration Pharmacokinetics Pharmacodynamics Sources of individual variation
What are the aspects of administration that influence intensity of drug response? dosage size, route, timing Medication errors Patient adherence
What is Pharmacokinetics? It is the movement of a drug and how it reaches it's site of action;or impact of body on drugs
What are the four major pharmacokinetic processes? absorption, distribution, metabolism, excretion
What is pharmacodynamics It is the impact of drugs on the body.
What is the process undertaken by a drug that induces a response body Drug-receptor interaction:binding to the cell's receptor; Patient's functional status influences pharmacodynamics (disease; Placebo effect determine response that a drug elicits.
Describe the therapeutic objective of drug therapy Provide maximum benefit with minimum harm where benefits outweigh risks
What are the factors that determine intensity of a drug responses Administration, Pharmacokinetics, Pharmacodynamics,and Individual variation
What are sources of individual variations that influence drug response? PHYSIOLOGIC: age, gender, weight; PATHOLOGIC: diminished kidney, liver function; GENETICS: may alter drug metabolism and predispose patient to unique interaction; Drug interactions
Key points about drug? All drugs cause harm and side effects; Obj is to provide max benefit with min harm; Drug therapy must be tailored for each individual.
What are the 6 rights of Drug Administration Right patien; right medication; right route; right time; right dose; right documentation.
What must the nurse know when giving drugs to a Pt Is Med appropriate for Pt? Any contraindication for Pt? Anticipate consequences of interaction b/t drug and Pt.
What are the responsibilities a nurse fulfills when administering drugs to a patient? Conduct a PREADMISSION ASSESSMENT relative to med; Determine dose and administer; EVAL and PROMOTE therapeutic effects; Minimize Adverse effects and interactions; Make PRN decisions; Manage toxicity by monitoring blood.
What is the goal of Preadmission Assessment? Gather baseline data to eval therapeutic responses and adverse effects; Identify High Risk Pts
Who is considered a high risk patient for drug therapy? Patient with Liver and kidney impairment; Genetic factors; Drug allergies;Pregnancy; Elderly and pediatrics.
What should the nurse do before administering a drug to a Pt? Read medication order; Verify Pt id; Read medication label; Verify dosage calculations; Implement any special handling instructions; Don’t administer drug if don’t understand the reason for its use.
what should the nurse know to EVALUATE a drug's therapeutic response? Know the rational for treatment; the nature, and time course of intended response.
What does the nurse promote to achieve a drug's therapeutic effects? Pt adherence (aka compliance or concordance) to the extent to which Pt's behavior coincides with medical advice.
What is another way therapeutic effects can be promoted? Implementing nondrug measures such as Biofeedback, emotional support, weight reduction, smoking cessation, sodium restriction
What should the nurse always now about adverse effects The major adverse effects the drug can produce The time when these reactions are likely to occur Early signs that an adverse reaction is developing Interventions that can minimize discomfort (ie food)
How does nurse minimize adverse effects Take a thorough drug history (allergies) Advise the patient to avoid OTC drugs that can interact with the prescribed medication. Monitor for adverse interactions known to occur. Be alert for as-yet unknown interactions.
What is important when nurse makes PRN decision? know the reason for the drug use assess the Pt's medication needs
When teaching the patient about dosage and adminstration, the nurse provides what information? Name of drug Dosage and schedule of administration Technique of administration Duration of drug use Storage of drug
When teaching the patient about Promoting therapeutic effects and minimizing effects? Nature and time course of expected beneficial effects
When educating Pt about minimizing adverse interactions, The nurse informs about what? hazardous drug-drug and drug-food interactions Example: phenelzine and amphetamines or figs
What are the nursing process steps for drug therapy? Preadministration assessment Analysis and nursing diagnoses Planning Implementation Evaluation
Preadministration assesment during drug therapy includes: Collection of baseline data to evaluate therapeutic effects Collection of baseline data to evaluate adverse effects Identification of high-risk patients Assessment of the patient’s capacity for self-care
Analysis and nursing diagnoses during drug therapy includes 3 objectives,what are they? Judge the appropriateness of the prescribed regimen Identify potential health problems that the drug might cause Determine the patient’s capacity for self-care
Planning during drug therapy includes: Defining goals Setting priorities Identifying specific interventions Drug administration Interventions to enhance therapeutic effects Interventions to minimize adverse effects Patient education Establishing objective criteria for evaluation
Implementation during drug therapy includes: Drug administration Patient education Interventions to promote therapeutic effects Interventions to minimize adverse effects
Evaluation during Drug therapy Includes Therapeutic responses achieved Adverse drug reactions and interactions Adherence to the prescribed regimen Satisfaction with treatment
