Study Notes
Drug Names and Classifications
- Drugs have multiple names: chemical, generic, and brand names.
- Understanding different names is crucial for accurate identification and safe medication administration.
Drug Action and Patient Response
- MEC (Minimum Effective Concentration): The minimum drug level needed to produce a therapeutic effect.
- Therapeutic Level: Drug concentration producing the desired effect without toxicity.
- Subtherapeutic Level: Drug concentration below the MEC, insufficient for therapeutic effect.
- Toxic Level: Drug concentration exceeding the therapeutic range, potentially causing harm.
-
Patient Experiences:
- Therapeutic: Desired effect, e.g., pain relief.
- Subtherapeutic: Lack of desired effect, e.g., continued pain.
- Toxic: Adverse effects, e.g., nausea, vomiting, organ damage.
Side Effects and Adverse Reactions
- Serious Adverse Reactions (e.g., anaphylaxis): Life-threatening, often requiring immediate intervention.
- Annoying Side Effects (e.g., nausea): Less serious, but can impact patient comfort.
- Anaphylaxis/Allergic Reactions: Characterized by sudden, severe allergic response with symptoms like hives, difficulty breathing, swelling.
Occult Bleeding
- Definition: Hidden blood in the stool, not visibly apparent.
- Examples: Certain drugs and diseases can cause occult bleeding.
First-Pass Effect
- Definition: The metabolism of a drug as it passes through the liver after oral administration, reducing the bioavailability.
- Explanation for Non-Medical Person: Imagine a drug traveling through the body after swallowing. The liver processes the drug first, reducing how much of it reaches the target area.
Pharmacodynamics vs. Pharmacokinetics
- Pharmacodynamics: How a drug works on the body's cells or systems. Focuses on drug action.
- Pharmacokinetics: How the body absorbs, distributes, metabolizes, and excretes a drug. Focuses on drug movement.
Reye Syndrome Risk Factors
- Note: Specific risk factors are needed to address this question.
Salicylism
- Definition: Toxic effect of salicylates (aspirin-like drugs)
- Patient Complaints: Symptoms that are a sign of toxicity include tinnitus, nausea, vomiting, dizziness, headache, and hyperventilation.
-
Risk Factors:
- Patients at risk include those taking high doses or prolonged use of salicylate-containing medications. Note: Detailed info about specific populations at risk is necessary.
Drug Classification Systems
- Review several systems for drug classification in books and educational materials.
Oliguria
- Definition: Decreased urine output.
- Suggestions it Suggests Suggests problems with kidney function requiring prompt investigation. Provide examples of what might cause oliguria.
Morphine IV Administration
- IVP administration time for morphine: Administered rapidly, generally over 2–5 minutes.
Pain Management Reassessment
- Importance: Periodic pain assessment after medication administration is essential for accurate dosage and optimal pain management.
- Patient Misrepresentation: If a patient reports feeling better but pain persists, it may indicate inadequate treatment; careful reassessment is necessary.
- Value of Good Pain Control: Appropriate analgesia promotes comfort, preventing complications and improving healing.
Steroid Adverse Effects
- Potential Adverse Effects: Discuss various steroid-specific adverse effects, including the long-term impact on metabolic processes.
- Safe Patient Teaching: Emphasize specific methods of steriod use to minimize adverse effects.
NSAID Adverse Effects
- Organ Affected: Primarily affecting the kidneys and gastrointestinal tract. Specific examples of adverse effects related to each of these organ systems.
Drug Interaction, Stacking
- Possible Interactions: Stacking medications in the same drug class can increase the risk of adverse effects, especially if there is an individual patient sensitivity.
- Exceptions: Consider exceptions to stacking under a doctor's guidance.
Opioid Potency
- Least Potent: List opioid medications least potent.
- Most Potent: List opioid medications most potent.
Specific Medications
- Summarize properties and actions of specific medications like meloxicam, nalbuphine, tramadol, and oxycodone.
Medication Teaching for Patients
- Provide clear and informative instructions on medication use. Give examples like:
- Safety: Proper storage and disposal of medications.
- Timing: Emphasizing medication timeframes as per dosage and frequency.
- Dosage: Correct medication intake based on patient instructions.
Adverse Effects of Opioids & NSAIDs
- Opioids: List various opioid adverse effects with detailed descriptions.
- NSAIDs: Categorize various NSAID adverse effects.
Opioids and Alcohol
- Risk: Combining opioids and alcohol significantly increases the risk of respiratory depression and other adverse effects. Explain the risk.
Fecal Occult Blood Test
- Positive Result: A positive result means that hidden blood is in the stool and needs further investigation.
- Relevant Medications: List medications that can cause occult bleeding.
