missed questions Flashcards
what does plasma do in the blood
transports carbon dioxide
diverticulitis, signs and symptoms
-lower, left-sided abdominal pain
-fever and malaise, body aches, chills, nausea and comiting
when are you likely to hear wheezing the loudest, with a pt experiencing an asthma attack
upon exhalation:
when does the second stage of labor begin
when fetus enters birth canal
why does wheezing occur?
because of swelling of bronchioles and bronco spasms
-high pitched, whistling breath sound, most prominent on exhalation
when does the third stage of labor begin
after baby is born until the afterbirth (placenta, umbilical chord, and some tissues from amniotic sac and lining of uterus is delivered)
what is left sided lung failure
lungs become congested with fluid because the left side of the heart fails to pump blood effectively.
-blood tends to back up un the pulmonary veins increasing the pressure in the lungs capillaries. When the pressure in the capilaries exceed a certain level, fluid passes through the walls of the capillary vessels into the alveoli, causing pulmonary edema
left sided lung failure, SS
pink, frothy sputum, and severe dyspnea
what happens in right sided lung failure
blood backs up in the vena cava, resulting in edema in lower extremities, or distention of the veins in the neck
ACS or acute coronary syndrom
term used to describe a group of symptoms associated with myocardial ischemia- decrease in blood flow to the heart, which leades to chest pain through reduced supply of O2 and nutrients to the tissues of the heart
what falls under the grouping of ACS
-unstable angina
-stable angina
-acute myocardial infarction
what is the difference between unstable and stable angina?
-unstable-pain or discomfort in the chest of coronary origin, that occurs in the absense of significant increase in myocardial oxygen demand
-stable- is characterized by pain in chest of coronary origin that occurs in response to excersize of some activity that increase the demand of the heart beyond the hearts capacity to increase its own blood flow
signs associated with early hypoxia
restlessness
irritability
tachycardia
first sign of heat stroke
confusion
placenta previa
-placenta covers cervix,
-moderate to severe bleeding
-painless`
abruptio placentae
separates from uterus wall, causing moderate to severe bleeding
-painful
spontaneous abortion
pregnancy complication, that commonly occurs in the first trimester,
cardiogenci shock
can show with chest pain
hypotension
fast heart rate
subarachnoid hemorrhage
bleeding in the space that surrounds the brain
chronic bronchitis S&S
chronic sputum-producing cough
wheexing
cyanosis
tachypnea
emphysema S&S
barrel chest
pursed lip breathing
dyspnea
cyanosis
wheezing/decreased BS
-seen mostly in older pts
Type I diabetes primary cause
pancreas does not produce insulin
Type 1 diabetes?
autoimmune disorder, produce antibodies against pancreatic beta cells.
-about missing pancreatic hormone insulin
-without insulin, glucose cannot enter the cell, and cell cannot produce energy
parasympathetic nervous system action
vasoconstriction
bradycardia
-this slows the heart and rr, constrict blood vessels in the muscles, and dilates blood vessels in digestive system
what happens when the brain activates PNS
the body will shunt blood to digestive organs to maintain homeostasis
ventricular tachycardia
heart arrhythmia, in which electrical impulses begin in ventricle instead of atria rate 150-250 bpm
ss:
chest pain,
unresponsiveness
impalpable radial pulse
-may even feel weak or lightheaded
-mb unresponiiive
signs of decompensated shock
-declining mental status
-labored or irregular breathing
-dilated pupils
-falling.blood pressure
-ashen, mottled, or cyanotic skin
-poor pee pee
how does naxalone improve ventilation in this patient
binds to opioid receptor sites, and blocks the effect of the drug, preventing uptake from CNS
if organs are outside of the body what do ya do
cover with moist, sterle dressings
cardiac tamponade traingle
(refered to as Beck’s Triad)
- JVD
-muffled heart sounds
-narrowing pulse pressure
