2.9. HTN = hypertension, high blood pressure

A little tension in life keeps things interesting, but if the pressure increases too much, something (like a blood vessel, or relationship,) might blow up.
A base level of stress improves focus, while too much stress leads to tunnel vision and helplessness. Hypertension in the brain can cause problems with memory and understanding (due to reduced blood flow to brain cells), an aneurysm (localized enlargement of artery), or dementia (chronic lack of blood flow to the brain).

The sympathetic nervous system dilates pupils so one can see better in a dangerous situation, but long term hypertension will damage blood vessels behind the eyes and lead to vision problems.

Our hearts beat faster and circulate more blood when we're excited, aroused, etc., nothing wrong with that, but if that tension persists, the hardworking left ventricle might grow thick and ineffective, and eventually fail. Damage and inflammation in arteries from high blood pressure can also lead to a heart attack or stro…

2.8. Cotyledon = embryonic leaf, or placental lobe

Religious or folk tales and heavy-handed symbolism aside (forbidden fruit, Snow White, One Tree Hunahpu), human mothers are like plants in many literal and practical ways.

They have ovaries, petals of sorts, and buds.

They each have special vascular systems for transporting the fluid that supplies gases and nutrients necessary for life.

They respond to seasons and have cycles. They are part of larger life cycles, and take part in a grand, ecological cycle as well.

They have cotyledons. Human cotyledons are plump, vascular lobes of maternal placenta. Plant cotyledons, two green halves of a split pea or edamame, are the food their mothers packed them so they could eat and grow.

Like plants making our atmosphere habitable and magically creating sugar out of simple ingredients, through the placenta mothers supply O2 and glucose for baby to use and help get rid of baby's CO2 and waste products.

They need water to live and function.

They are endlessly resilient at every stage of life, b…

2.7. Gravida = a pregnant woman

There is such a thing as being a little bit pregnant, presumably pregnant, or probably pregnant before one is positively pregnant. Cis men can have hysterical pregnancies (Couvade syndrome), while a positive pregnancy test could be the result of medications or a (non-pregnancy-related) medical condition.
Image source: Crash Course
Presumptive Signs of Pregnancy: "presumptuous" signs perceived by the woman may be caused by just about anything other than actual pregnancy.
1. Absence of menstruation: could be stress, very low or high body weight, excessive physical activity, just late, or menopause.
2. Nausea & vomiting: stress, food poisoning, overindulgence/ having too much fun (without occurence of conception).
3. Breast changes: PMS.
4. Fatigue: anemia, sleep deprivation, or does one need a reason to be tired? How about being a woman in the first place and having to worry about all of this, and everybody else, too?
5. Urinary frequency: possible UTI, or too much liquid, …

2.6. SN = Student nurse

Dear Student Nurse,

Today is the first clinical day of the rest of your life.

You're probably nervous; you might be scared. In fact, you're probably petrified. But remember: you have been prepared. You have practiced your skills, gotten items in your little white book checked off, received 90-100% on your math, and most of all, know how to stay safe to protect you and your patient(s).

You will make mistakes. You will forget things. You may be sentenced to Mandatory Skills Lab of Shame. You will linger in skills lab anyways, with or without sentencing, because you need to practice that urinary catheter insertion for the 50th time on the dismayed mannequin, or practice drawing up with a blunt needle every last drop of fake medicine in a leaky 1ml vial without getting bubbles, no flicking allowed. You may cry at some point (public meltdown in the computer lab; driving down G St.; secretly, at night)--this is normal. Common, even. Don't let things get to you; just do better ne…

2.5. OT = Oxytocin

I. Oxytocin, sometimes called the love hormone, or the bonding hormone, is important right from the beginning of one's life. Released in large amounts during labor, it is responsible for uterine contraction, milk ejection, maternal behavior, and bonding. It is also related to arousal, orgasm, generosity, trust, healing, and other generally good things.   Above and below are crystallized, stained images of oxytocin, courtesy of a polarized light microscope. Everything, including intelligence, looks prettier crystallized, refracting all the colors of the rainbow.

II. Serotonin, a monoamine neurotransmitter, regulates mood, appetite, and sleep (also, gastrointestinal motility/activity, but nobody cares about that.) It also affects memory and learning. Many antidepressants act through increasing the availability of serotonin (in all its diverse, layered beauty, seen below,) at the synapses of the central nervous system.
III. Estradiol is an estrogen steroid hormone involved in the deve…

2.4. Evisceration = exiting of viscera

Sometimes a feeling of evisceration, of being gutted, emptied out from the inside, is not a metaphor.

The below scene is summarized from p. 269 of Ignatavicius & Workman's Medical-Surgical Nursing, 8th ed.

Readers who get queasy easily are advised to stop here. Here's a cute package of sterile gauze to look at instead : )
Those of you still here, it's still highly advised that you never Google Image the word, "evisceration."

After abdominal surgery, it is important to splint the incision site with a pillow to support the integrity of stitches/staples/sutures while coughing, sneezing, or laughing really hard, or things will cease being funny really fast.

It is possible for the insides to bust through sutures and spill outside, piling up on top of the abdomen, especially if the patient is already crashing and emergency chest compressions are taking place.

Should this occur, call for help (surgeon, rapid response team) immediately, but do not leave the patient a…

2.3 IV = Intravenous (therapy)

Things learned during IV insertion skills lab: Hydrate well so veins are plump and popping and unlikely to collapse or constrict and shrivel in fright, practically disappear. Disappearing won't stop someone from sticking the vein, will only increase the likelihood of the catheter needle missing its mark, poking all the way through the vessel, digging around, backing out, making more holes all the way up the dorsal metacarpal or cephalic veins.

Veins can be slippery, roll-y little buggers. Go too slow with the needle and the target vein will literally roll to the side from light pressure, some kind of magical, evolutionarily-fit way to evade thorns, pricks, and accidental bleeding-out. Unfortunately, blood vessels have not yet evolved to tell the difference between life-saving IV antibiotics and malicious pricks.

Slapping the vein to make it pop really hurts (especially if the instructor does it), more so than the needle poking around later, or the bruise that will soon form.

A &q…
