1
Q

Meaning of this word?

A

Excessive potassium in the blood

2
Q

Normal Potassium Range?

A

3.5 - 5.1

3
Q

Hyperkalemia range?

A

Anything higher than 7.0 or higher is very dangous

4
Q

Where is Potassium found?

A

Most of the body’s potassium is found in the intracellular part of the cell compared to the extracellular which is where sodium is mainly found. Blood tests that measure potassium levels are measuring the potassium outside of the cell in the extracellular fluid.

5
Q

What is Potassium Responsible for?

A

Remember that potassium is responsible for nerve impulse conduction and muscle contraction.

6
Q

Saying for Causes of Hyperkalemia?

A

“The Body CARED too much about Potassium”

7
Q

“The Body (C)ARED too much about Potassium”

A

Cellular movement of potassium from ICF to ECF (Burns , tissue, damages, acidosis)

8
Q

“The Body C(A)RED too much about Potassium”

A

Adrenal Insufficiency with Addisons Disease

9
Q

“The Body CA(R)ED too much about Potassium”

A

Renal Failure

10
Q

“The Body CAR(E)D too much about Potassium”

A

Excessive Potassium Intake

11
Q

“The Body CARE(D) too much about Potassium”

A

Drugs (Potassium-Sparing drugs like Aldactone , Triamterene, ACE Inhibitors, NSAIDS

12
Q

Saying for Signs and Symptoms of Hyperkalemia?

A

MURDER

13
Q

(M)URDER

A

Muscle Weakness

14
Q

M(U)RDER

A

Urine Production little or none (renal failure)

15
Q

MU(R)DER

A

REspiratory Failure (due to the decreased ability to use breathing muscles or seuzires develop

16
Q

MUR(D)ER

A

Decreased cardiac contractility (weak pulse, low blood pressure)

17
Q

MURD(E)R

A

Early signs of muscle twitches /cramps .. late profound weakness, flaccid

18
Q

MURDE(R)

A

Rhythm changes: TRall peaked T waves , flat p waves, Widened WRS and prolonged PR interval

19
Q

Nursing Interventions for Hyperkalemia

A

Monitor Cardiac, Respiratory, Neuromuscular, Renal, And GI Status

Stop IV Potassium if Running

Potassium Restrictive Diet

20
Q

Dialysis Consideration

A

Prepare patient for ready for dialysis. Most patient are renal patients who get dialysis regularly and will have high potassium.

Kayexalate is sometimes ordered and given PO or via enema. This drug promotes GI sodium absorption which causes potassium excretion.

May order Lasix to remove Potassium

Administer a hypertonic solution of glucose and regular insulin to pull the potassium into the cell
