Help!! Case Scenario 45 y/o M w/diabetes post op revascularisation (PAD)

Published

Hi Everyone,

I am new here, so please be gentle. So below me I have a case scenario, my assessment is to pick the highest priority out of 5 clinical problems. At first I was going to choose Problem #4 altered blood glucose level .

The reason , because dehydration will take a few hours to rectify, he needs more urgent treatment because he has already got paralysis, his altered BGL is the reason for all the problems listed. I feel that once that is addressed then all other problems will be like a domino effect.

As you can see from below I have changed my intervention to addressing dehydration instead. I had queried this with other uni students and most seem to think that dehydration is it!!

They said I was diagnosing the fact that he may have HHNS when he may be on his way to that state but isnt yet.

The question is to justify my reasoning of why dehydration is of the highest priority, I guess I'm just reaching out for a second opinion, after all if I can justify with a decent rationale then I'm sweet.

Cheers Sian

CASE SCENARIO

Mr George Brown, a 45-year-old male, has been admitted to a ward and has undergone a limb revascularization procedure following experiencing severe leg pain on his anterior right lower leg. The following data were obtained on admission: Subjective data: (reported by Mr Brown's friend) - Diagnosed with type 2 diabetes mellitus 2 years ago - Diagnosed with peripheral arterial disease (PAD) 1 year ago - 2 year history of hypertension - 10 year history of smoking - Taking oral hypoglycaemic medications and anti-hypertensive medications Reported by Mr Brown: - Feeling 'weak' with nausea and vomiting 2 days prior to admission (don't know what has caused him to feel like this) - Extremely thirsty (caused by the dehydration which in turn caused by vomiting and also hyperglycaemia would be aggravating his fluid loss)

- Foot and leg ache continually -( better at rest) (Dehydration causing hypotension which decreases blood flow to the periphery, aggravating the effects of his PAD) Objective data: - Drowsy but can be roused (dehydration) - Dry mouth (dehydration) - Skin dry and warm with decreased turgor (dehydration) - Weight 132 kgs - Height 170 cms - Blood glucose level 21mmol/L (will be increased due to reduced volume of water in his blood - hence increased concentration of all elements in the blood) - Serum potassium level 6mmol/L (as above) normal range 3.5-5.0 mmol/l - Lipid profile: total 253 mg/dl; LDL 91 mg/dl; HDL 25 mg/dl; triglycerides 423 mg/dl (as above) - Diminished peripheral pulses (aggravated with hypotension which accompanies severe dehydration) - Ankle-Brachial Index 0.4 (severe PAD) normal 0.90-1.30, decreased peripheral blood flow due to severe hypotension in a patient with PAD. Previous hospital admission for: - Hyperosmolar Hyperglycaemic Nonketotic Syndrome (State) 2 months ago (>34mmol/l) - ST-segment elevation myocardial infarction 12 months ago Social: - has 3 children visiting, who live with ex-wife - has been working as a real estate agent 20hrs/wk ASSESSMENT Mr Brown presents with multiple clinical problems. Five of Mr Brown's problems are: 1. Altered serum potassium level 2. Dehydration 3. Decreased level of consciousness 4. Altered blood glucose level 5. Paraesthesia (abnormal feelings i.e. pins and needles) and paralysis (loss of ability to move one or all limbs)

Hi gold I do know what Paresthesias is :)

the paralysis is mentioned (as well as the Paresthesias) in the case study.

The only information myself and the Op has is on the first post... unfortunately not much to go off :(

HI! Gold is how many stars I have from my posts....I'm Esme

It is difficult because I don't have your information and when it is incomplete on the thread I can't be completely accurate.

So he has an elevated temp....what other information do you have? Can dehydration cause a temp? What do you do for a fever?

Your priority is dehydration. Why? Because after oxygenation (which appears OK based upon the data you give) the next most important basic human need is fluid and electrolyte balance. You did not tell us what his serum chemistries are, but chances are very good the BUN and creatinine are quite elevated.

His K+ is high because he's dehydrated, and thus he is not perfusing his kidneys well. Give him fluid replacement, the kidneys should kick in and the K+ will come down. BUT WATCH OUT!!! Are you going to give him insulin to treat his hyperglycemia? Insulin drives K+ into the intracellular space. If you aggressively and unwisely treated his hyperglycemia you could find your patient suddenly hypokalemic (and dead.)

Dehydration (or more properly hyperosmolarity) is his priority problem because his level of consciousness is impaired. CNS neurons are telling you he has to be hydrated NOW.

Some (probably not all but some) of his fever can be related to dehydration. More to the point, you don't know how much of the fever is true fever until his fluid imbalance is corrected.

Fluid imbalance is your problem because he's got a fever and this drives his insensible fluid loss up, aggravating dehydration. If his output has been low and his blood sugar high, I'd worry about urosepsis. But you analyze fever in the following order: Wind (lungs), water (cystitis, pyelonephritis), wound, and "walking" (this relates to DVT but they had to have a "w" to keep the alliteration going).

You didn't tell us what his chemistries are but (counterintuitively) his serum sodium is likely low. (You see this when there is hyperglycemia. The hypothalamus is telling the kidneys to dump sodium in a desperate attempt to correct the osmolality.) That is why the patient needs normal saline. He has lost sodium in excess of water.

So... dehydration first. Potassium balance second (but not simply hyperkalemia. Beware sudden hypokalemia!)

First an easy way to make the conversion from mg/dl to mmol/L is to divide by 18. To convert mmol/L to mg/dl, multiply by 18.

The glucose is 380.CASE SCENARIO

You prioritize according to what is going to kill him first. So looking here what is most important?

Potassium. An elevated K can cause lethal cardiac arrythmias. Why is this patients glucose elevated? How does and elevated glucose impact the elevated K? http://www.elsevierhealth.com/media/us/samplechapters/9780443071973/9780443071973.pdf

The next would be dehydration....why is he dehydrated? Well he stated he had nausea and vomiting prior to admission. Why was he vomiting? Well....he has a history of HHNK. The chances this has reoccurred are high. Is his elevated sugar causing nausea and vomiting due to the stress his body being stressed from an occlusion of his lower leg? I think his compliance might be an issue as well.

Altered blood glucose. The elevated glucose will affect healing and contributes to his overall health picture.

Decreased LOC. Patients with elevated glucose that are dehydrates with nausea and vomiting and dehydration will have a decreased LOC and an elevated K

Now looking at these symptoms what disease process causes these symptoms? the hint is in his PMH

Pain. Your patient has pain.

He is at risk for further peripheral circulatory occlusions and infection due to his disease process, poorly maintained health (still smoking), and fresh post op

What are your thoughts? Do you use NANDA I? What semester are you? What did your instructor say?

Hey Esme12,

Your brain amazes me :) haha. Sorry it's taken a bit to get back.

I'm 3rd year 1st Semester. My tutor did get back to me and has stated that I go through each clinical problem and find out which one is worse for his case. not much help really. Although he did specify these questions which really do have me in a pickle now...

So he said to research these:

T2DM/PAD; Altered mobility; Acute Pain; Altered BGL; Altered Serum Potassium Level and Dehydration.

And answer these:

How do these problems affect patients?

Which one is the highest priority?

Which problems can lead to serious complications?

How do these complications occur in the body? - Why is this important?

How quickly can these complications occur in patients like Mr Brown?

Which complications are the most serious for Mr Brown?

I think you are bang on the mark, my query now is that he is post op and reading up on perioperative phases etc the dehydration issue should have been addressed prior to anasthesia (preop checklist) ...otherwise the nurses/doctors would be putting the patient at a huge risk considering he has previously had an MI.

So... it makes sense (sort of) that maybe dehydration is not the highest intervention right now! Hmmm...I'm still on struggle street.

So what do you get from his potassium level 6mmol/L and normal range is 3.5-5.0mmol/l? Slightly elevated or is this a serious elevation?

I also do believe he may be in pain hence his level of conciousness - drowsey but can be roused, however that can also be the anathesia wearing off.

What you have stated regarding his nausea and vomitting is also an issue i.e. with his BGL's, non compliancy and dehydration.

Unfortunately I do not know what NADA 1 is. Sounds important though :(

the patient is definitely at a high risk of infection and I'm pretty sure thats where our question 2 comes in to play.

Your information is highly regarded. It does give me some light at the end of the tunnel haha!

Hey tulip5,

Thanks for your input :) I need all the help I can get right now.

In regards to the case study it does state he is post op after a limb revascularization. Do you think the patient's dehydration should have been adressed pre op (preop check list) prior to procedure considering the medical staff could put him at rish considering he had a Myocardial infarct previously? If you still consider it being dehydration, can I please ask how? (thats a serious question by the way). Is it because of his elevated BGL's? or potassium levels?

Pain is definitely an issue here. All the information I have on the case study i have uploaded on this forum lol and I wish they did give us more info, but I guess that would make it too easy. Thinking outside the box now :)

Hey I'm doing this case study too! :o

It's dehydration from what I've found out so far and that is what my tutor said as well. From starting him on a sodium chloride infusion it will prompt diuresis and also the blood level will be higher so the ratio to potassium will be lower. Also you need to start a sodium chloride infusion as this is done before a attacking his bsl (journals). His circulation will also be improved and loc. His paralyiss will be improved as well.

I have a question too!

the second question of the case study is

"Mr Brown has a further problem of an orally taken temperature of 39o C. He is complaining of general

discomfort related to his body temperature. Identify the best management for the above problem in

Mr Brown’s case. Using an academic writing style, justify your decision for Mr Brown’s body

temperature management in this admission with a synthesis of evidence-based literature. (approx.

750 words). "

Apparently he has an infection and we have to find out what sort of infection it is (via my tutor) is osteomylitis a good one? why/ why not?

Hey l1234567,

Glad you and I are in the same boat haha :(

Dehydration seems too easy in this case study though. I have and still am researching the dehydration part but there is something I am not completely satisified with, I'm missing something. Everyone (fellow students) are saying dehydration, and it doesnt matter what clinical problem you choose as long as you can justify it with an awesome rationale. So meh ha!

However in regards to question 2, I did hear my tutor say he has an infection and it is up to us to figure out what type of infection through signs and symptoms:

Managing temperature

T2DM/PAD

Hyperthermia

Fever

Anti-pyretic

and....

What does the HIGHEST LEVEL of evidence say about managing temperature/fever for

hospitalised T2DM patients osteomylitis...his words exaclty so osteomylitis it must be lol!!

NANDA I is what we use here in the US for nursing diagnosis.

NANDA International (formerly the North American Nursing Diagnosis Association) is a professional organization of nurses standardized nursing terminology that was officially founded in 1982 and develops, researches, disseminates and refines the nomenclature, criteria, and taxonomy of nursing diagnoses
Welcome to NANDA International - Defining the Knowledge of Nursing 'What do you use for nursing diagnosis? I have to run out for a bit But I will be back

So if I understand your current question(s). (1) Why am I adamant his priority problem is dehydration? The answer is: fluid imbalance (current... not risk for) always ranks everything else except issues of oxygenation. End of story. Is your instructor asking you to justify your nursing diagnosis? If so, that's the answer.

(2) Why is pain not up there as a top priority? Because it won't kill him. Also because with a clouded sensorium we really don't know what his subjective experience is. It's tough to know. First... I don't want to treat what I can't assess and second... he is so unstable I don't want to push much opiate just this minute.

(3) Is your instructor asking you WHY the pt. is dehydrated? Because he's so hyperglycemic, his renal threshold has been exceeded, he's loosing lots of glucose into the filtrate, and it's dragging water with it. (Osmotic diuresis.)

(4) Pre-operatively, it would have been insane to operate on the guy in this condition. (Nothing will heal when there is hyperglycemia) and his graft is going to fail because of the dehydration and other derangements. So I have to think, he became a metabolic mess post-operatively.

(5) What is the source of the infection? Without further assessment, it's impossible to know. But, figuring it out would mean checking first his lungs (CXR, physical assessment) and then water (urinalysis) then wound (which will not be healing because of the hyperglycemia), then looking for DVT (and he's probably on heparin post-operatively to keep the graft from clotting off, so that's unlikely.) I'm thinking they were trying to revascularize the leg to save a foot which likely has infected bone in it or something and the osteo is distal to the graft.

Bottom line (take it to the bank) your priority problem is fluid imbalance (dehydration). Your secondary problem is hyperkalemia but the correction of his high sugars will tank it, so you would just watch it as you gave insulin and normal saline. Your third problem is likely infection (which will make his sugars go way up due to stress hormone... cortisol) So insulin, saline, and antibiotic... prescribed by the MD, obviously.

There has to be missing information from your assignment. From the information here I would not assume the patient has osteomyelitis.

There is definitely something missing. You have presented no evidence that this patient has osteo. Nor that he has paralysis. The lethargy can be from HHNK and non ketotic coma. IN the US temps are treated but cautiously because it may suppress the immune response to fight infection.

What has your research shown about treating a temp and infection.

We are happy to help but we will not do the work for you.

Is this a med school student case study? Cuz I'm seeing a lot of medical diagnostic problems and treatment guesses here, and not seeing a lot of nursing diagnosis or care. Of course it's useful, yea, critical, to understand the underlying medical diagnoses and physiological processes underlying a patient's presentation, but ... nursing, nursing, nursing, please.

And second the comment about do your own homework, and asking an online forum for the answers is not research.

Thanks Grntea for your input,

However, I'm not looking at diagnosing I am simply asking a question due to confusion and I'm second guessing myself so am aiming for a second opinion.

Before you jump on forums, my suggestion to you would be to dont jump to conclusions unless you actually are aware of the situation. Perhaps trying a more poilte approach and asking next time instead of assuming.

Its nice to get a professionals opinion sometimes...you know?? Have a nice day :)
