Quiz One Flashcards
Be able to give 5 examples of causes of delirium.
D-Drugs (Continuous drips, Na+, Ca+, BUN/Cr, NH3+) E-Environmental factors (hearing aids, eyes glasses, sleep/wake cycle) L-Labs (Na, K, Ca, BUN/Cr, NH3+) I-Infection R-Respiratory Status (ABGs, PaO2, PaCO2) I-Immobility O-Organ Failure U-Unrecognizable Dementia S-Shock (Sepsis, cardiogenic, steroid)
What are the different features that are associated with the definition of delirium
1)Acute Changes or fluctuating Mental status 2) Inattention 3) Altered LOC or Disorganized Thinking
ABCDE Protocol
Awakening and Breathing Coordination Delirium Management Exercise and Mobility It is important to know so that the RN and Rt can coordination the SAT and SBT trial to be done together Rt can help with the non pharm intervention in delirium management RT may help with airways in early exercise
What is you ICP normals
10-15 mmHg
How to calculate MAP
(Systolic + [Diastolic *2]) /3
Ideal CPP
>60-70 But may depend on dr. Orders
Jugular Venous Saturation
Measures SjvO2 (could also give PO2) Gives a global approximation Can be used both as a spot check and continuous monitor
Cerebral Oximetry
SO2 of the underlying tissue Can be continuous or used for spot checks
Licox
PO2 of underlying tissue Is a continuous measurement
What type of ICP monitor allows for concurrent EVD
Fluid filled system where catheter is inserted into the ventricle of the brain
What is the relationship between SjvO2, Cerebral Metabolic Rate, and Cerebral Oxygen Therapy Delivery
SjvO2=(Cerebral Oxygen Delivery)/(Cerebral Metabolic Rate)
GCS-Motor Response
6-Obey Command
5-Localizes to pain
4- Withdrawl frm pain
3- Adbnormal flexion
2-Abnormal extension
1-No movement
GCS-Verbal Response
Oriented (5) Confused (4) Inappropriate Words (3) Inappropriate sounds (2) No Response (1)
GCS-Eye Opening Response
Spontaneously(4) To Speech (3) To Pain (2) None (1)
Glossopharyngeal Nerve
Cranial Nerve IX Gagging and swallowing (Sensory) and taste Assessed through oral care
Vagus Nerves
Cranial Nerve X Gagging and swallowing speech and cough Assessed through suctioning
RASS -3
Patient has any movement in response to voice but no eye contact
RASS -4
Patient has any movement to physical stimulation
RASS -5
Patient has no response to any stimulation
RASS
- Observe the Patient-The patient is alert, restless, or agitated (Score 0 to +4) 2.If Not Alert, State Patient Name and Ask to Open Eyes and Look at Speaker-Patient awake with sustained eye opening and eye contact (Score -1) Patient awakened with eye opening and eye contact, but it is not sustained (Score -2) Patient has any movement in response to voice but no eye contact (Score -3) 3.There is no response to verbal stimulation, physically stimulate by shaking shoulder and/or rubbing sternum •Patient has any movement to physical stimulation (Score -4) •Patient has no response to any stimulation (Score -5)
Sedative
any drug that reduces CNS arousal Sleep is not the same as sedative Benzodiazepines Nonbenzodiazepines Barbituates
Hypnotic
any drug that induces sleep
Anxiolytic
any drug that reduces symptoms of anxiety
Analgesia
any drug that reduces the sensation of pain General anesthesia has four characteristics: unconsciousness, analgesia, muscle relaxation, and depression of reflexes.
Anesthetics
any drug that reduces the ability to perceive sensations
Pharmacological Therapies
Many drugs can have multiple effects! Effect(s) often dose dependent Can get sedation effects at low dose and full anesthetic at high dose. Most available evidence regarding sedatives and analgesics in ICU patients indicates that it may be less important which drugs are delivered than their proper titration using goal-directed delivery (RASS Target) to optimize patient comfort while avoiding complications such as prolonged mechanical ventilation or reintubation
Benzodiazepines
Sedatives/Hypnotics/Anxiolytics Used for its effects of sedative (madadala), hypnotic (valum), anxiolytic Used to treat: anxiety, agitation, insomnia, seizures/ status epilepticus, muscle spasms, alcohol withdrawal (DTs) Can be short, intermediate or long-acting (longer-acting used for anxiety) Outside ICU used for anxiety and insomnia-Note: there are other benzo’s that are prescribed for assisting with sleep Some common benzo’s used for anxiety/hypnotic effects
Benzodiazepines Cautions
Can cause loss of airway reflexes at high doses and decreased tidal volume at lower doses
