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 "blown vein" is one that has been ruptured and is now bleeding beneath the skin. This often forms a hematoma, a green, blue, or darkened, painful area. For photographic documentation, see classmates' social media pages/stories.

Venous blood is very dark, deeper than Merlot, looks like poison.

"We have a bleeder!"

This is probably the only time seeing blood will make a student nurse happy--a smooth IV insertion, the "flashback" of red in the plastic chamber. However, it's not a successful insertion until blood actually returns to the syringe, the saline pushes in, everything is properly connected, sterile, and taped correctly, with minimal scrambling, patient complaints, or instructor eye-rolling.

If all else fails, hospitals have vein finders, which are super awesome and make tattoos and non-venous-bits fluorescent, which might entertain the patient briefly while a third nurse takes a stab at one of his last possible arm veins before a doctor's order needs to be obtained to move on to lower extremities.

3.2. ABO = blood type

In parts of Asia, people don't just consult the zodiac, star signs, and the eight numbers of one's birth (八字). There's an entire culture of personality decoding based on blood type. It all started in 1927 when Takeji Furukawa, a professor at Tokyo Women’s Teacher’s School, shared his research connecting personality traits with blood type. Since then, friends and romantic interests ask if one's A, B, AB, or O, and in Japan, people reportedly get discriminated against at school and work based on their blood type.


Correlation of personality with one's A, B, AB, or O blood has not been supported by many credible studies, but some people take this very seriously. If you know your blood type (and you really should), see if the traits below sound about right.

A: Contrary to the Western concept of a "type A personality," people with type A blood (and antigens) can take a long time doing something when they're not motivated, or finish the same task in a jiffy …

3.10. Crisis = time-limited, disruptive, challenge

Are you in a crisis? According to Erik Erikson, we all are. Erikson divides psychosocial development into eight stages. Each period comes with its own "crisis," which once resolved, yields an appropriate "virtue."

0-1.5 years: Baby learns to trust, or mistrust the world. The former yields hope; the latter does not. Seems like many of us are still working on this one.
1.5-3 years: Toddler's crisis (or rather, Toddler's parents' crisis) involves a battle between autonomy v. shame & doubt. Making it through this stage confirms the child's (free) will. No, _____, this does not mean you always get your way.
3-5 years: The Preschooler may struggle with initiative v. guilt, but "purpose" emerges as a way to make sense of it all (hence the Why? why? Whyyyyyyy? WHHHYYY?s). A little bit of guilt here and there is fine for the developing ego and superego.
5-12 years: The School-age Child feels anxious about industry v. inferiority, ideally striv…

TKD = taekwondo

We interrupt our regular programming of blood, guts and babies to talk about taekwondo, a traditional Korean martial arts form.

Tae = kick/strike with the foot.
The foot as a blade, as hammer, as hook, the blow that knocks someone out, a broom sweeping the enemy down, pushing an intruder to the ground.

Kwon = punch/strike with the hands.
The hands, fist or palm, can be knives, blocks for poles, a punch to the solar plexus, bladed support when one rolls or falls, or a friendly hand to help a competitor back up from the mat.

Do = the art, the way of life.
Like any relationship, one's journey in martial arts has ups and downs. There's a honeymoon period, initial excitement--passion or obsession, even. That may not last, but commitment does. There are milestones but also little bumps, minor or major injuries. Things get in the way of training, but some amazing people also support one along the way. Sometimes one learns to find fun in dressing in full storm-trooper sparring gear on a …
