Chapter 1 & 2:

 Medications: amiodarone, lidocaine, magnesium, procainamide, and

vasopressin  these are antiarrhythmic used in life threatening cardiac

problems

Alpha 1- cause skin and mucous membranes to vasoconstrict

Beta 1- stimulate the heart (you have 1 heart)

Beta 2- affects heart and lungs (you have 2 lungs) bronchodilation in lungs, and

uterine smooth muscle to relax.

Dopamine- causes renal blood vessels to dilate

Epinephrine- triggers alpha 1, and beta 1 and 2 receptors. Vasoconstriction,

increased HR, and bronchodilation SE: Hypertensive crisis, dysrhythmias, angina,

Dopamine- triggers dopamine receptors, beta 1 receptors, useful for shock and

heart failure

Dobutamine- triggers beta 1 receptors (heart rate increased, and used for heart

failure)

CH. 3 Neurologic diagnostic procedures

Cerebral angiogram: catheter inserted in groin or neck. Contrast dye is used so be

aware of pregnancies, shellfish and iodine allergies, check for patient’s renal

function (BUN, creatnine). Check is patient is on anticoagulant because bleed risk.

NPO 4-6 hrs before procedure. After procedure, check distal pulses and bleeding at

site.

EEG: Used to detect seizures, but can also check for sleep disorders and behavioral

changes. Wash hair prior to hair, and be sleep deprived, don’t have to fast for this.

This stress can trigger seizures or abnormal brain activities.

Glasgow Coma scale: how we determine level of consciousness. Highest score is 15;

anything less then 8 is severe head injury and coma. 4 are eyes opening.

Intracranial pressure & monitoring: If someone has a low Glasgow scale more

monitoring needs to be done. High infection risk with the machine that is taking

pressure.

Symptoms in increase ICP: irritability, headache, decreasing LOC, no pupil response,

alterations in breathing, decorticate posturing. Normal intracranial pressure should

be between 10-15.
