PHARMACOLOGY-NURS 3502-EXAM 1 STUDY GUIDE
CHAPTER 1: CLINICAL JUDGEMENT MODEL
Clinical Judgement Model – Purpose and Components
Recognizing cues
• This step involves collecting patient information from both subjective and objective
sources.
• Subjective data includes what the patient or family reports about the condition.
• Objective data consists of measurable or observable findings gathered by the nurse.
• Nurses also ask direct questions to better understand the patient’s condition.
• Information is collected from multiple sources such as:
o Physical assessments of all body systems
o Medical records (history, labs, vital signs, and documentation)
• From this data, the nurse identifies relevant cues (important, related findings) and
irrelevant cues (unrelated or non-contributing findings).
• This step corresponds to the assessment phase of the nursing process.
Analyzing cues (interpreting problems)
• In this stage, the nurse interprets the collected data to identify patient problems.
• Cues are evaluated in relation to the patient’s history and overall condition to determine
appropriate care needs.
• The nurse determines which findings support or rule out potential health problems.
• This step is part of the analysis phase of nursing.
Prioritizing hypotheses (ranking problems)
• Patient problems are identified and then organized by importance.
• Once data is analyzed, hypotheses (possible problems) are formed.
• Problems are ranked based on urgency, severity, risk, and timing.
• Abnormal findings help define the patient’s primary concerns.
• The nurse decides which issues require immediate attention and which are less urgent.
• This also falls under the analysis phase.
Generating solutions
• The nurse develops a care plan based on identified problems.
• Expected outcomes are established for the patient.
• Interventions are evidence-based actions designed to achieve those outcomes.
• Outcomes must be patient-centered, measurable, and include a timeframe for evaluation.
• This represents the planning phase of nursing.
Taking action
• The nurse implements the planned interventions.
• This includes medication administration, patient teaching, and direct care.
• Priority actions are determined based on the most urgent patient needs.
• This is the implementation phase of nursing care.
Evaluating outcomes
• The nurse assesses whether the patient’s condition improved after interventions.
• Outcomes are compared with expected goals to determine effectiveness.
• Interventions are classified as effective, ineffective, or unchanged in outcome.
• If goals are not met, the care plan is revised accordingly.
• This is the evaluation phase of the nursing process.
,Clinical judgment definition
• Clinical judgment refers to the result of critical thinking and decision-making based on
patient data and clinical experience.
Patient Teaching for Medications – Key Points
• A patient’s willingness and readiness to learn significantly influence education success.
• Medication teaching should include:
o Name of the medication
o Reason for use
o Dosage and timing schedule
o Instructions for proper administration
o Possible side effects
o Ways to reduce or manage side effects (e.g., avoiding sun exposure with
photosensitive drugs)
o Serious adverse reactions and when to report them
o Contact information for the healthcare provider
o Warnings specific to the medication (e.g., avoid alcohol use)
o Dietary instructions, including foods to avoid or include
• Nurses must maintain patient confidentiality (HIPAA compliance).
• Assess the patient’s health literacy before teaching.
• Encourage teach-back or return demonstration to confirm understanding.
• Provide clear, simple written instructions including provider and pharmacy contact
details.
CHAPTER 2: ETHICAL PRINCIPLES AND RESEARCH
Core Ethical Principles in Clinical Research
Respect for persons (informed consent and autonomy)
• Patients must be treated as capable individuals who can make their own healthcare
decisions.
• They should receive full information about treatment options and possible consequences.
• Autonomy refers to the patient’s right to make independent decisions about care.
• Healthcare providers must respect patient choices even if they disagree, unless the
decision places others at risk.
• Patients may refuse treatment or withdraw from research at any time without penalty.
Beneficence (risk–benefit balance)
• Healthcare professionals have a responsibility to protect patients from harm.
• Research must clearly define risks and potential benefits.
• The expected benefits must outweigh potential risks.
• Risks may include physical, psychological, and social harm, all of which must be
evaluated.
Justice
• Research participants must be selected fairly.
• Benefits and burdens of research should be distributed equally.
• Participant groups should represent diverse social, racial, and ethnic populations.
Informed Consent – Components
• Informed consent ensures voluntary participation without pressure or coercion.
, • It is a continuous communication process, not just a signature.
• It demonstrates respect for patient autonomy and promotes active participation in care
decisions.
• Patients must be mentally alert and able to understand the information provided.
• Consent documents should be written at or below an eighth-grade reading level and use
simple wording.
Phases of Clinical Research
Preclinical trials
• Conducted before human testing begins.
• Includes laboratory (in vitro) and animal (in vivo) testing.
• Evaluates toxicity, drug absorption, distribution, metabolism, and elimination.
• Assesses genetic toxicity and overall safety.
Phase I (human testing – small group)
• First testing in humans.
• Focuses on safety, dosage range, and identifying side effects.
• Conducted with a small number of participants.
Phase II and III (larger trials)
• Phase II: Expands to larger groups to evaluate effectiveness and continued safety.
• Phase III: Large-scale testing to confirm effectiveness, compare treatments, monitor
adverse effects, and ensure safe use in the general population.
CHAPTER 3: PHARMACOLOGY
Pharmacokinetics vs. Pharmacodynamics
Pharmacokinetics (what the body does to the drug)
• Describes how a drug moves through the body: absorption, distribution, metabolism, and
excretion.
Absorption
• Movement of a drug into the bloodstream after administration.
• Influenced by:
o Age (slower with aging)
o Gastric acidity (changes with age, medications, and food)
o Food intake
Distribution
• Movement of drug from bloodstream into tissues.
• Influenced by blood flow, membrane permeability, protein binding, and cardiac output.
• Highly perfused organs (heart, liver, kidneys) receive more drug.
• Poorly perfused tissues (fat, muscle) receive less.
• Depends on protein binding and free drug levels.
Metabolism (biotransformation)
• Chemical alteration of drugs into forms that can be eliminated.
• Mainly occurs in the liver.
• Liver disease (e.g., cirrhosis, hepatitis) can reduce metabolism.
• Half-life determines how long a drug stays active.
• Steady state occurs when drug input equals elimination.
• Typically reached after about four half-lives.
• Loading doses are higher initial doses used to reach therapeutic levels quickly.
