What is the 3 letter position abbreviation

(R/L) occiput positions to the R/L side of mothers pelvis
presenting parts (O, S, M) occiput, sacrum, mentum
-(A/P) occiput positioned to the anterior or posterior portion of the pelvis

What is difference between fetal station and fetal engagement

Fetal station is a measure of thee degree of descent in birth canal using spines
Fetal engagement is the fetus basing Through maternal pelvic brim

What is the difference between gynecoid, android, anthropoid, and playlpelloid pelvises

Gynecoid - normal round circle
Android —heart shaped
Anthropoid — vertical oval
Platypelloid —flat pelvis

What is primary and secondary powers

Primary powers are involuntary uterine contractions
Secondary- bearing down efforts
— may have to turn down epidural for mom to feel urge

What is fetal adaption

Fetal circulation
Fetal respiration—chemoreceptors prepare the fetus for intimating respiration immediately after birth

What are physiological adaption to labor for maternal adaptions

Increase cardiac output,
Inc O2 consumption
Proteinurea
Decreased absorption and N/V
Increase metabolism, dec BS
Increase WBC

Considered normal
Highly predictive of a normal fetal acid-base balance
Represents adequate cerebral oxygenation

Perfectly

What does minimal or absent variability mean

Can result form hypoximia
Congenital anomalies and preexisting neurological injury
CNS depressant medications (analgesics, barbiturates, tranquilizers, phenothiazines, pentobarbital, anesthetics
—also sleeping

What are the three main causes of fetal tachycardia

Study These Flashcards

Maternal fever
Maternal infections
Early fetal hypoxia
-maternal hyperthyroidism
-drugs

What are some causes of fetal Bradycardia

Study These Flashcards

True bradycardia occurs rarely
Fetal cardiac problem
Viral infections
Maternal hypoglycemia
Maternal hypothermia

What are periodic changes vs episodic

Study These Flashcards

Periodic = associated with uterine contractions
Episodic= not associated with contractions

What is different between acceleration and prolonged acceleration

Prolonged is greater the 2 minutes, but less than 10

What causes acceleration

Uterine contractions, spontaneous fetal movement, electrode application, fetal scalp stimulation, No nursing intervention required

What is early deceleration

Gradual decrease and then return of FHR associated with contractions Causes are head compression, baby is on the way

What is late deceleration

Late recovery Usually a perfusion issue from uteroplacental insufficiency Related to uterine contractions contraction

What is the most common cause and intervention for late decelerations

Uterine tachysystole, usually caused by oxytocin administration Also: supine hypotension, epidural anesthesia, post-dates, hypertensive disorders, Abnormal patterns cased by fetal hypoxia, academia, and low apgar score

What is LION PUT

Lateral change of position of mom Increase IV fluids oxygen on mom Notify provider Pitocin decrease Interventions for late decelerations

What are variable decelerations

Usually have U, V, W shape characterized by rapid descent Associated with cord compression Reposition mom

What if changing positions does not relieve variable decelerations, what do you do

Discontinue oxytocin (pitocin) Administer O2 Notify provider Pit

What are the causes of prolonged deceleration

When teh mechanisms responsible for late or variable decelerations last more than 2 minutes Maternal hypotension Uterine tachysystole or rupture Extreme placental insufficiency Prolonged cord compression

How long should a contraction be, and how long should the resting tone be

Contraction 50 to 70 seconds, Resting should be at least 30 seconds

Variable decelerations, what is the cause and management

Cord compression, maternal reposition

Early decelerations, what is the cause and management

Head compression, identify labor progress

Acceleration, what is cause and management

Okay, no interventions

Late deceleration, what is cause and management

Placental insufficiency Execute interventions, lion pit

What is the emergency severity index

1 being most urgent, 5 being least

What is the mass casualty triage

Red- emergent Yellow urgent Green non urgent Black deceased

Upon primary survey of Airway, what does AVPU stand for

Alert Responsive to voice Response to pain Unresponsive

What is primary survey

Airway Breathing Circulation Disability Environment Full set of vitals Get monitors and give comfort

What is secondary survey

History Inspect posterior Just keep reevaluating

From hisotry and head to toe of secondary survey, what does SAMPLE mean

Symptoms Allergies Medications Past medical history Last oral intake Events/environment preceding illness or injury

In the emergency department, what is the most important vital sign

What is therapeutic hypothermia

32-36 C Provided 24 hours after ROSC Decrease mortality and improve neurological outcomes

What are 2 sedative meds

Propofol, dexmedetomidine

What are some paralytic meds

Nimbex, cistracurium, vecuronium

T.F must sedate patients to paralyze them

What are medication considerations to avoid delirium in ICU

Use haldol or dexmedetomidine with caution, along with benzodiazepines

T.F parental nutrition has low dextrose compared to Peg tube feedings

What are Hs for ventricular dysrhythmias

Hypoxia Hypovolemia Hyperthermia Hydrogen ions (acidosis) Hypo/hyperkalemia

What are the Ts for ventricular dysrhytmias

Tension pneumothorax Tamponade Toxins Thrombosis Trauma
