the bridge we trek
is the road we take
to our next destination.
to our next destination.
it is nothing but a mere dash or hyphen
stuck between point A and B.
oh yet, how this bridge intimidated us.
it was wooden and it was wobbly.
unsteady to the touch,
uneasy on the eyes.
it made us second guess ourselves,
and caused our anxiety to erupt as it has never done before.
with the crowd of travelers beside us
and the glorious reward just the end of the way,
how could we possibly think about turning around?
winds of worry,
waves of tears,
earthquakes of nervous tremors,
and typhoons of complications,
life tried to destroy this bridge,
so it appeared,
a thousand times over.
but we did not fret,
not enough to jump off at least.
for the crowds of travelers surrounding us
soon became friends.
a new support system flourished.
sturdy beams of friendship,
arches of comic relief,
and caring ears smoothed the path over.
there were even bright lights,
in ever changing forms,
which illuminated the way,
making the bridge we trek
not so unbearable after all.
we have made it through one year friends.
you could say the worst part is over,
or the hard part is only beginning,
but halfway home sounds much better.
congratulations on completing one year of nursing school!

It Don't Come Easy
It used to be easier, dealing with death.
Oh, occasionally a particularly devastating case would get to me, but I worked codes with professional detachment and took care of the surviving family members with compassion and professionalism.
It used to be easy.
It’s not so easy anymore.
*****
I knew you for a little over an hour, and the minute I saw you I knew you were dying. War had been raging inside your body for over three years; you met every battle with determination.
The enemy was pernicious. Malevolent. This particular enemy always is. Silent until its damage is irreparable, it was now ready to end its rampage.
I knew it. And so did you. In the few words we exchanged, you told me you were ready to “turn the page”; you were so exhausted.
Bone weary. Exhaustion so deep that you didn’t have the energy to even want to fight anymore.
I gave you my hand. You gave it a squeeze.
Peace was at hand.
Twenty minutes later you were gone.
*****
As I watched your monitor slowly dissolve into that undulating line of asystole, my throat tightened and my eyes burned. I made sure your family members were comfortable and I went to the nurses station to do the required paperwork. That infernal, damned paperwork.
You had just died, but God forbid that I do anything but the required paperwork. It was the most important aspect of the night.
Not the fact that I was ready to cry. I made it to the bathroom, but that made it worse so I swallowed hard, came back out and talked to your doctor, the coroner and the donor network, finished your chart and sent you to our “refrigeration unit”. That’s what the transplant coordinator called it. Guess “morgue” is no longer PC.
I didn’t even know you.
But two hours later I was crying for you on my way home from work.
*****
Why is dealing with death becoming so much harder? As a young nurse, it was what I did.
It was also something that happened to other people.
Is it my age that makes me more aware of my own mortality, making death that much harder to deal with?
Is it that I have now buried my parents-in-law, my father, three grandparents, an uncle, an aunt and two brothers-in-law, the last four within the last 18 months?
Is it because I know the feeling of the shock that sets in immediately following the split second of disbelief or the depth of the sadness that precedes the seemingly endless, painful ache?
*****
I’m not sure what it is, but the more I experience death, the more it affects me and the harder it is to control my emotions.
I wondered if maybe it was time for me to get out of this line of nursing, that maybe I had lost the ability to detach enough to remain the impartial professional.
Then I realized, after all these years I should be thankful that I can still feel for my patients and grieve their loss.
When I stop feeling for my patients, that would be the time I would need to explore another avenue of nursing.
As for now, I’ll stay right where I am.

"Hey I'm a fun guy!"
Here's a joke told by a patient in Suite A at CMH to Dr. Zia, his case manager, and to the three of us doing rounds:
A mushroom wanted to make some people laugh. He starts dancing around and making faces but they are not amused. So, the mushroom leaves and comes back in a clown suit. They still don't think it's funny. The mushrrom gets frustrated and says, "Oh, come on! I'm a fun guy!"
Ha Ha...get it? fun guy...fungi...

Learn your ABG lab values...
just a few tips for nursing 4 that seems to help:
Isabel Romena-
-powerpoint presentations are directly from the book, DIRECTLY, but it is a good idea to read over them anyway, particularly the NP
>not all information from the ppt will be tested
-listen during lecture, paying special attention to scenarios she brings up, many of these show up on the test
>"So your neighbor complains to you about symptoms she has been experiencing..."
>"What would you do if a patient is exhibiting these symptoms..."
>there are also personal experiences she brings up to incorporate into lecture
-do the study guides
-read the chapters, but not the whole thing, there is too much! instead take the questions from the study guide and read the section corresponding to it.
>ie: the study guide question is asking about types of fractures, read that entire section because small details show up on the tests at times
>if you cannot read, read the related charts at minimum
-know your diagnostic tests and labs, not necessarily the ranges, but diagnostic tests/labs which can diagnose a patient's problem or determine if a treatment is working effectively
-know your "at risk" patients for each disease studied
-and no...the Lewis study worksheets were not THAT helpful
Caralee Bromme-
-a majority of test questions come from the lecture
-points which are emphasized during lecture are generally tested
-know your diagnostic tests and ranges for labs
-answer the study guide questions from the lecture first, particulary the NP questions
-understand pathology of the disease process
-make certain you understand the concept of fluids and electrolytes
*continue to perfect your testing skills using ATI practice tests, test banks, and the program in the nursing computer lab...
Don't forget to take care of yourself!!!

Exam #6: Ch. 62-65 (Musculoskeletal System)
KEEP ON TRUCKIN...FINAL FOR N004!!!
1. Explain the effects of aging on the MS system.
-joint and muscle discomfort
-loss of bone density
-decreased tendon flexibility and muscle strength
-vertebral disc compression causing loss of height
2. Explain the different diagnostic tests of the musculoskeletal system and related nursing care.
*standard x-ray: determines bone density
-avoid unnecessary exposure and ensure patient is not pregnant
*diskogram: contrast dye x-ray to determine intevertebral disk abnormalities
-assess for allergy
*CT scan: identifies soft tissue and bony abnormalities and musculoskeletal trauma
-painless, assess for allergy
*myelogram: sensitive test able to pick up nerve impingement and subtle lesions and injuries

California Pizza Kitchen Fundraiser
Next Thursday, the Student Nursing Association will be holding a fundraiser at California Pizza Kitchen. Just show up to California Pizza Kitchen and buy something to eat or drink and hand them a flyer and 20% of the bill will go to the Student Nursing Association. The fundraiser was scheduled between the two classes so that it gives everyone a time to relax and talk to other nursing students there about what to expect for the rest of the semester. It will be a great time to find out about the Nursing 4 and 5 classes and encourage the Nursing 2 students. I tried to add a copy of the flyer at the bottom of this post. You should be able to click it to open it so you can print one yourself. If you can't print one feel free to email me and I can send you a copy of it. If you have any questions just ask!

Missing Classes?
The counseling office recommends getting transcript evaluations before graduation. This way, the student knows which classes still need to be completed before receiving a degree. Right now is a good time to do so because it takes some time for them to evaluate the transcript. All you need is an official transcript of all schools attended and an evaluation form from the counseling office. Once the paper is filled out, turn it into Admissions and Records. Find out what classes you need because the summer is a perfect time to complete these classes!

Exam #4: Ch. 17, 48-50 (Endocrine System)
Ch. 17-Fluid and Electrolytes
1. Review calcium regulation.
-present in the body as free or ionized, bound to proteins like albumin, and complexed with phosphate, citrate, or carbonate
-serum calcium levels reflect all three forms
*plasma acidosis: decreases albumin bound calcium, thus increasing ionized calcium
*plasma alkalosis: increases albumin bound calcium, thus decreasing ionized calcium
*calcium balance controlled by parathyroid hormone (PTH), calcitonin, and vitamin D
-PTH: produced by parathyroid gland and stimulated by low serum calcium
>increases movement of calcium out of bones, GI absorption of calcium, and renal tubule reabsorption of calcium
-calcitonin: produced by thyroid gland and stimulated by high serum calcium
>opposes PTH action—decreases GI absorption, increases calcium deposition into bone, and promote renal excretion
-vitamin D: formed through UV rays in precursors found in skin or diet
>aids in absorption of calcium in GI
2. Identify clients at risk for calcium imbalance.
*hypercalcemia
-hyperparathyroidism
-malignancies: cause bone destruction from tumor invasion or secrete a parathyroid-like protein to stimulate calcium release from bones
-vitamin D overdose
-prolonged immobility: bone mineral loss and increased plasma calcium concentration
-rarely occurs from increased calcium intake
*hypocalcemia
-removal or injury of parathyroid gland
-acute pancreatitis: causes lipolysis which produces fatty acids that combine with calcium ions

1. Review the normal regulation of hormonal secretion.
-stimulate or inhibit hormone synthesis or secretion using:
*simple feedback: based on blood levels of a particular substance
-negative feedback: increase or decrease of secretion depending
>calcium regulation: low serum calcium stimulates PTH to increase calcium levels, once achieved the increased calcium levels inhibit further PTH release
-positive feedback: increases target organ action beyond normal
>pressure receptors in the vagina during birth stimulate more oxytocin secretion to make stronger uterine contractions
*complex feedback: hormone stimulation or inhibition involving multiple glands
*nervous system control: hormone secretion directly affected by nervous system actvity like pain, emotion, sexual excitement, and stress
*physiologic rhythms: secretions by rhythms originating in the brain structure like the circadian rhythm related to sleep-wake or dark-light cycles
2. Review the actions of the different hormones and their sources.

-increases calcuim reabsorption and phosphate excretion
-stimulates conversion of vitamin D in most active form to enhance intestinal absorption of calcium
**adrenal glands
*adrenal medulla
-catecholamines: stress response neurotransmitters
*adrenal cortex: any hormones secreted are referred to as corticosteroids except androgens
-cortisol: glucocorticoid; regulates blood glucose concentration by stimulating hepatic conversion of amino acids to glucose; necessary to maintain life

-Type 2 DM: pancreas can produce insulin, but is insufficient and/or poorly utilized by the body
-Gestational: high blood glucose during pregnancy and high risk of developing type 2 diabetes
-Pre-Diabetic: not enough to be diagnosed, but high risk of type 2 diabetes if not treated
>Fasting glucose and OGTT higher than normal

Ch. 48-Nursing Assessment: Endocrine System
1. Review the normal regulation of hormonal secretion.
-stimulate or inhibit hormone synthesis or secretion using:
*simple feedback: based on blood levels of a particular substance
-negative feedback: increase or decrease of secretion depending
>calcium regulation: low serum calcium stimulates PTH to increase calcium levels, once achieved the increased calcium levels inhibit further PTH release
-positive feedback: increases target organ action beyond normal
>pressure receptors in the vagina during birth stimulate more oxytocin secretion to make stronger uterine contractions
*complex feedback: hormone stimulation or inhibition involving multiple glands
*nervous system control: hormone secretion directly affected by nervous system actvity like pain, emotion, sexual excitement, and stress
*physiologic rhythms: secretions by rhythms originating in the brain structure like the circadian rhythm related to sleep-wake or dark-light cycles
2. Review the actions of the different hormones and their sources.

Ch. 49-Nursing Management: Diabetes Mellitus
1. Differentiate the pathophysiology of the different types of DM.
-Type 1 DM: destruction of islets by immune system, therefore there is a little to no insulin production
-Type 2 DM: pancreas can produce insulin, but is insufficient and/or poorly utilized by the body
-Gestational: high blood glucose during pregnancy and high risk of developing type 2 diabetes
-Pre-Diabetic: not enough to be diagnosed, but high risk of type 2 diabetes if not treated
>Fasting glucose and OGTT higher than normal
-Secondary Diabetes: result of another medical condition or treatment which causes high glucose levels
2. Differentiate normal, pre-diabetic, and diabetic blood-glucose levels.
-normal: 70-120 mg/dl

*HHS: inadequate hydration paired with polyuria cause blood glucose to be >400 mg/dl and high serum osmolality
*hypoglycemia: too much insulin in proportion to glucose in the blood
*hyperglycemia: too much glucose in proportion to insulin in the blood
8. Use the NP to provide care for a patient with DKA, HHS, and hypoglycemia
**DKA

-if after 2-3 doses of simple carbohydrates do not work or the patient is not alert
--administer 1 mg of glucagon IM or SQ
--give complex carbohydrate after recovery
--20-30 ml D50 IVP in acute care setting
9. List and explain the chronic complications resulting from diabetes.
*microvascular angiopathy: thickening of capillary and arteriole vessel membranes particularly in the eyes, kidneys and skin
