Lab Values
What is the normal value for Potassium (K)?
What is 3.5-5.0 mEq/L?
What imbalance occurs when the serum level falls below 135mEq/L , hint Critical RED FLAG: <120
What is Hyponatremia?
What should the nurse assess for when the serum sodium reaches 115 mEq/L?
What is - the nurse should assess the client for clinical manifestations of lethargy, increasing intracranial pressure, and **seizures?
Oliguria is defined as urine output less than ___________mL/kg/hr.
What is .5?
A physician orders regular insulin 10 units I.V. along with 50 ml of dextrose 50% for a client with acute renal failure. What electrolyte imbalance is this client most likely experiencing? What is the rationale?
Yes!!! A 2 part question!!
What is hyperkalemia
Insulin rapidly shifts potassium into the cells. Since we are administering insulin, the clients blood glucose drops, therefore we have to replace it. This takes place in either the ED or ICU setting.
What is a normal sodium level (NA)?
What 135 -145 mEq/L?
What lab values are associated with Hypokalemia? Can you also identify the critical lab value?
Just need to answer one to receive the 200 points.
What is Potassium serum below 3.5 mEq/L, Critical RED FLAG: <2.5?
What nursing interventions are appropriate
to include in the plan of
care for a client w/ Hyponatremia?
List (5)
What is:
Administer Sodium containing IV fluids
*NS 0.9% or 3%
Reduce water intake
Monitor electrolytes
*Monitor vital signs
*Monitor neurological responses/Mental Status
*Headaches
*Monitor fluids/I&O for overload
*Weights daily
*Monitor musculoskeletal-cramps/ weakness/tremor
How should you prepare for clinical? Name 5 things that you should do to set yourself up for success!
What is:
Get a good nights sleep!
Lay out your uniform, supplies, paperwork the night before.
Be neat, clean, no fake nails, no heavy perfumes! Save that for the weekend :)
EAT breakfast and drink fluids - We don't need to call a RRT on our students!
Leave your troubles at the door. Get in the right frame of mind.
Leave early, arrive on time!
Have a positive attitude, be ready to jump in and help!
What organ is primarily responsible for potassium excretion?
What are the Kidneys?
Fun Facts:
Hyperkalemia seldom occurs in patients with normal kidney function.
Kidney function should be monitored through BUN and creatinine levels and urine output if the patient is receiving potassium replacements!
Therefore the nurse should know that Potassium supplements are extremely dangerous for patients who have impaired kidney function and decreased ability to excrete potassium.
Even more dangerous is the IV administration of potassium to such patients because serum levels can rise very quickly.
What is the normal lab value for Magnesium (Mg)?
What is 1.3-2.6 mEq/L?
What are the lab values associated with Hyperkalemia?
What is serum above 5.0 mEq/ ?
Critical RED FLAG: >6
What concentration of potassium can the nurse administer safely through a peripheral IV?
What is a peripheral IV line is 10 mEq/100 mL at a rate no faster than 10 mEq/hr.
What electrolyte imbalance should the nurse monitor for in a client taking furosemide?
What sport did Dr. Hagen play in college?
Hint...her kids play this sport, and she talks about it ALL THE TIME!
What is Lacrosse?
What is the normal Blood Urea Nitrogen (BUN) level?
What is 10-20 mg/dl?
What BUN value would be a critical red flag?
What is greater than >100mg/dl?
List 5 Nursing Interventions for a client who is diagnosed with Hyperkalemia.
What is:
Administer Insulin/D50
Administer Calcium Gluconate
Administer Potassium wasting diuretic (furosemide)
Place on cardiac monitor - looking for peaked T waves and wide QRS complex
Irregular heart rate and rhythm for increased ectopy-PVC’s/Vtach
Monitor neurological responses, mental status, headache
***Lose points if say "kayexolate" - that is no longer current practice.
What is 0.5 mL/kg/h?
What electrolyte imbalance are you primarily going to see with kidney failure?
Hint: it is the leading cause of cardiac arrest in clients with Kidney failure.
What is Hyperkalemia?
What is the normal Brain Natriuretic Peptide (BNP) level?
What would an elevated level indicate?
**Yes! This is a 2 part question - it's for 500 points- it wasn't going to be easy***
What is <100 ng/L?
This is a lab that would indicated heart failure. It is a biochemical marker of severity of congestive heart failure.
Which lab is the most sensitive indicator of renal function?
What is the normal value?
Yes! This is a 2 part question!!!!
What is Serum creatinine?
The normal value is Normal: 0.5-1.2 mg/dl
What are appropriate nursing interventions when administering potassium replacement with a concentration of potassium greater than 20 mEq/100 mL
List 3 interventions
What is: The potassium must be administered through a central IV catheter using an infusion pump with the patient monitored by ECG.
What is the name of Dr. Hagen's Dog?
There is an EXTRA 100 points if you can guess his breed!!
What is Tank?
He is an English Staffordshire Bull Terrier... he is not a Pitbull, or an American Staffordshire....although he looks just like one.
