Video Summary - 7ª AULA FUNDAMENTOS BÁSICOS DA PRÁTICA ASSISTENCIAL

Main ideas, concepts, and lessons (7ª AULA – fundamentos básicos da prática assistencial)

1) Course logistics + institutional messages

7th lesson topic: Basic principles of clinical practice, focused on patient safety during preparation and administration of medications.
Announcements:
- The General Knowledge Week is ending soon.
- Students should watch three live streams (topic: sovereignty/society/power/regulation/data in the digital age).
- There is an assignment worth up to 1 point toward the final grade.
- Students are encouraged to explore the learning environment (shared info, infographics, instructor videos, and forums).
Academic integrity message:
- Every assessment is an opportunity to build real skills/knowledge.
- Cheating and misuse of materials (including selling/sharing exam questions) violates academic integrity and can lead to academic/administrative sanctions, and potentially civil/criminal liability depending on misuse/dissemination.

2) Teaching approach and structure of the class

The class is designed to be dialogical, with student participation via chat and answers. The lesson includes:

A commented question
A case study
Practical visualization (simulation/laboratory demonstrations applying the concepts)

Core clinical content: Medication safety and patient safety principles

3) “10 rights” of medication administration (with one added right)

The instructor references a framework that evolves to 10 rights and emphasizes: students should not memorize them mechanically—each one supports safety in real clinical incidents.

Key risks highlighted before the checklist

The most serious risks discussed in chat focus mainly on:

Wrong medication
Wrong dose
Wrong technique/route
Wrong timing/patient

Central idea: serious harm can occur beyond “infection”, including life-threatening complications and even death.

The “10 rights” (checklist)

Right patient
- Verify at least two identifiers (e.g., full name + date of birth, not only bed number).
- Bed numbers and wall identification can be wrong due to patient transfers/record mix-ups.
Right medication
- Confirm the medication name precisely (look-alike/sound-alike names are major risk points).
Right route (oral, IM, SC, intradermal, IV)
- Different routes change absorption rate and risk profile.
- Incorrect route administration can be fatal.
Right time
- Administer within the prescribed schedule/interval.
- Timing delays can compromise therapy (especially emphasized for antibiotic schedules).
(Prescribed scheduling concept tied to the time right)
- Medication schedules follow SOP/service routines and must be renewed with new chart days/records.
- Nurses document administered times so the next shift continues safely.
Right assessment
- Assess patient before and after administration.
- Check for:
  - Allergy history
  - Vital signs and medication-related changes
  - Clinical conditions that make administration unsafe (e.g., pediatric fever sensitivity/seizure risk)
Right documentation/record (correct record)
- Record administration in the medical chart (legal documentation + safety for continuity).
- Documentation protects both patient and professionals.
Right guidance/instruction to patient/caregiver
- Explain purpose/effects and what to expect (to handle refusal or misunderstandings).
- If the order seems incompatible with usual route/indication, the nurse should question the prescriber.
(Right response / expected effect follow-up)
- Observe whether the medication achieves the expected effect.
Right to refuse
- The patient or legal guardian may refuse if the patient is capable (e.g., lucid/oriented).
- If refusal occurs, the team must:
  - Provide guidance
  - Confirm capacity/conditions
  - Obtain a signed refusal form when possible
- If no legal companion is available, handle immediate responsibility first, then proceed via legal channels.

Patient safety tools: verifying prescription details

4) Prescription verification and labeling essentials

Medication safety depends on confirming prescription information, including:

Medication name
Quantity/dose
Route
Time of administration

If only partial info is available (e.g., name + dose but missing route/time), risk increases.

The instructor also stresses a cultural warning:

Do not assume “it’s common” or “they said it verbally”—verification must be explicit and documented.

5) Shift changes and responsibility

When prescription changes or clarifications are needed:

If a doctor is no longer present after shift change, responsibility for verification/confirmation falls to the incoming professional(s).
If professionals refuse to redo changes, they must identify and confirm with another professional—but the medical prescription responsibility cannot be treated as someone else’s when verification is required.

Medication timing and scheduling (practical safety rationale)

6) Why timing matters

Correct timing prevents:

Improvisation of schedules by the nurse/team
Disruption of antibiotic therapy
Misalignment between doses (e.g., delaying every interval shifts the next-dose windows)

Example scheduling logic shown:

Every 12 hours starting at 10:00 → 10:00, 22:00, etc.
Every 6 hours or every 8 hours → repeated intervals across the day

If delays occur, traceability and professional responsibility must reflect that reality.

Practical skills: injections, needles, and angles (methodology)

7) Recommended non-invasive routes discussed (injection-related)

The instructor distinguishes:

IM (intramuscular): 90° angle to muscle tissue
SC (subcutaneous): 45° to 90° angle into subcutaneous tissue
Intradermal: into dermis; described visually as approximately 15°
IV (intravenous): into the vessel (technique differs by device/route)

8) Why needle angle and depth matter

Correct depth affects:

Absorption and medication effectiveness
Risk of delivering into the wrong tissue layer
Potential complications from incorrect placement

9) Needle identification: gauge, color, and standardization

Needles differ by:

Gauge/thickness (G)
Color coding
Intended use/route

The instructor notes:

Color coding is internationally standardized and references ANVISA/ANVISA-related standards.

General rule:

Higher gauge number → thinner needle
Higher G is smaller/thinner

Examples mentioned:

Colors associated with certain gauges (e.g., pink for larger gauge; gray for smaller gauge)
Exam tip: memorize color–gauge associations (including heuristics such as “rose for aspiration”)

10) Needle/infusion device categories shown

Scalp vein needles / butterfly needles
- Wing-shaped design for easier puncture
- Used for rapid infusion and situations needing short-term IV access (especially in elderly/children)
Peripheral IV cannulas (GEs / “gelcos”)
- Sizes selected based on vein size/fragility and infusion goals
- Not random—chosen to prevent leakage/rupture
Infusion set components
- Drip chamber, vent/piercing tip, roller clamp, tubing
- Importance of setting drip rate correctly
- Air-venting prevents vacuum issues
Multiple access devices
- Four-way polyfixes: multiple medications via the same venous access point
- Three-way stopcock / extension sets: more movement freedom; fewer repeated punctures and reduced contamination risks

Syringe sizing and volume limits (instructional content)

11) Syringes match route and volume needs

Intradermal/SC routes use very small-volume syringes (example guidance references insulin syringe concepts).
IV syringes use larger graduation scales (example references ranges like 10 mm/20 mm in the instructor’s explanation).
Syringe choice must consider:
- Route
- Required volume
- Age/physiology

12) Age-based volume limits

The instructor emphasizes:

Elderly and children often need smaller volumes and appropriate needle sizes to avoid tissue damage/abscess and to support correct absorption.
Volume guidance varies by muscle size and patient age (e.g., newborns have smaller maximum volumes; older children use different muscle sites).

Case study (exam-style reasoning)

13) Case: medication safety checklist—what went wrong

Scenario presented:

Patient bracelet says: Maria José da Silva
Chart shows: Maria José dos Santos (name discrepancy)
Medication (dipyrone) prepared by another professional; injection planned into the deltoid
Patient reports allergy to dipyrone, but the allergy is not recorded

Questions:

Which “right” was not followed and could risk the patient?
- Guided answer: Right patient / wrong patient due to wrong identification
What actions should be taken before administering any medication?
- Confirm patient identity with proper identifiers and resolve discrepancies
Additional clinical checks included:
- Allergy verification
- Correct syringe suitability (e.g., insulin syringe not appropriate for IM route)
- Correct IM angle (90°, not 45°)

Key corrections emphasized:

Use proper identifiers (not only bed number)
Do not proceed with suspected IM using an inappropriate syringe/route depth
Confirm allergy information and injection-site/technique requirements

Demonstration/simulation: IV antibiotic preparation/administration safety (procedure logic)

14) Practical steps emphasized during the simulation

Hand hygiene and glove changes when switching routes/medications
Validate catheter/IV access before use (e.g., aspirate blood return)
Track IV access time on adhesive tape to maintain safety window
Preparing infusion:
- Close clamps/rollers appropriately before connecting
- Remove protective barriers without contaminating areas contacting medication/patient
- Slowly puncture the saline bag port using the piercing tip to avoid leaks/contamination
Continual focus on:
- controlling contamination risk
- correct sequence and handling of equipment

Exam-style multiple-choice scenario (patient safety responsibility)

15) Question presented during class

Scenario:

Nurse observes an IV antibiotic being administered 2 hours early compared to prescription.
Nurse stops infusion but:
- does not inform the patient
- does not record the event in the chart

Options included:

A: correct without informing/recording
B: incorrect because nurse should inform patient and document
C/D: other justifications about no additional risk or limited notification

Correct answer stated: Option B Reason: patient safety principles require informing the patient and documenting the event in the chart.
