Q

Lab value for serum creatinine and what kind of test is it?
What is creatinine
How does it compare to BUN
What do different levels mean?

A

0.6-1.3mg/dl blood test
A waste product from mm and protein. It is not reabsorbed in the kidneys and is there for a reliable indicator of kidney function.
It is more accurate than BUN
Increase=inflammation or infection, kidney damage
Decrease=malnutrition

Q

What is GFR normal value and what kind of test?
What does it say about kidney function?
How accurate is it?

A

> 90ml/min It is based on creatinine, age, sex, and race and it estimates the GFR.
If it is decreased then we have decreased kidney function
It is very accurate because it measures GFR and that is the best indicator of kidney function.

Q 
Prerenal AKI 
What is oliguria from?

What do we treat?
What can it lead to?
A

Decreased volume of blood not damage to parenchyma
Because of low BP kidneys are trying to raise BP by saving NA+ and H2O RAAS

Q

What defines oliguric stage value
When does it happen-3
How long does it last
Prognosis?

A

A reduction of urine output of less than 400ml a day. Usually happens within 1-7 days of injury but if ischemia is present than 24 hours. If from drugs it might be a week.

Q 
Describe diuretic phase of AKI 
UOP
WHy?
One thing
How long 
Two more things
A

UOP- 1-3 lt sometimes 5 or more. It is from osmotic diuresis from high urea concentration. Kidneys can excrete waste but cant concentrate it. Can last 1-3 weeks. BUN and creatine start to stabilize.

Q

Recovery phase of AKI
starts when?
What does recovery look like 4

A

Starts when GFR starts to increase and BUN and c start to decrease Major improvement in first 1-2 weeks. Full recovery can take 2 months.

Q

Below list 5 complications of MG as a result of the muscle weakness in specific muscle groups.
What crisis and what are the s/s?

A
  1. ptosis/facial drooping
  2. difficulty with speech
  3. issues with chewing food
  4. problems with swallowing
  5. difficulty breathing (increased risk for aspiration and infections).

Other complications: fatigue, risk of falls/injury
These complications are associated with the lack of Ach and subsequent progressive muscle weakness. Muscle weakness in the face, neck and chest are especially concerning because they are vital for eating/swallowing/breathing.
Myasthenic Crisis-Exacerbation, worsening of mm weak like swallowing and breathing

Q

RA

A

Rheumatoid arthritis is a systemic autoimmune disease that is characterized by inflammation of connective tissue in diarthrodial (synovial) joints. The person will have fever, fatigue and potentially organ involvement. Joint stiffness is a common symptom and can last several hours. There is a genetic predisposition associated with RA. Unlike osteoarthritis, those with RA experience periods of remission and exacerbation.

Q

You are doing patient teaching on the treatments used in RA. Explain in layman’s terms to the patient the types of drug therapy used in RA, how they work and any side effects of the drug therapy.

A

DMARDs (Disease Modifying Antirheumatic Drugs) are the main treatment for slowing the disease progression and decreasing the risk for joint erosion or deformity. Methotrexate is the preferred DMARD. Methotrexate side effects include bone marrow suppression and hepatoxicity. Lab monitoring must take place -therapeutic levels can be reached in 4-6 weeks.

Q

Pharmacology of fibromyalgia: How do tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs) work in the treatment of fibromyalgia? How do muscle relaxers work to treat fibromyalgia?
Two common drug tx
One last thing

A

TCAs and SSRIs are used to relieve pain and helping with depression and treat insomnia that comes with the debilitating nature of extreme pain.
