Potassium, Hyperkalemia, Hypokalemia
Also Consider: Abnormal lab result
Potassium, Hyperkalemia, Hypokalemia
Also Consider: Abnormal lab result
Decreased Level (hypokalemia)
Symptoms: constipation, weakness, cramps. arrhythmias, paralysis
Common causes: medications, malnutrition, vomiting, diarrhea, low magnesium level
Increased Level (hyperkalemia)
Symptoms: arrhythmias
Common causes: kidney problems, medications, lab error (hemolysis)
1. Take Vital Signs
Temperature:
Blood Pressure:
Heart Rate:
Respiratory Rate:
Oxygen Saturation:
2. Evaluate Symptoms and Signs
Acute mental status change
Not eating or drinking as much as usual
Cardiovascular: new irregular pulse
GI: Nausea, vomiting, diarrhea, constipation, heartburn, abdominal distention or tenderness, rebound tenderness, bowel sounds
GU: New or worsened incontinence, pain with urination, blood in urine, urinary retention / bladder scan
Neurologic changes: weakness, gait changes (unsteadiness, loss of coordination or balance)
Very low urinary output (<30cc/hr)
Fingerstick glucose (patients with diabetes)
3. Take Action using SBAR Report:
Immediately notify the medical staff & resident representative
Potassium less than 3.0 or greater than 6.0, OR
Any abnormal level in a patient on digoxin
Notify medical staff & resident representative within the next 16 hours.
Potassium between 3.0 and 3.5 OR higher than normal but <6.0
SBAR Report
Situation: (High) (Low) "Potassium level of ___ “ (in a patient on digoxin)
Background:
Reason the patient is in the nursing home (rehab for___, long term care for __).
Reason the test was done
When the problems started, how severe they are, getting worse or staying the same, what treatments have been used.
Abnormal vital signs
History of kidney disease or dialysis
Recent illness, medication changes
Presence of diarrhea, vomiting, poor oral intake
General observation of patient condition
Diuretic use & recent dose changes
On medication that increases potassium level: Potassium Chloride, ACE inhibitor, spironolactone, trimethoprim/Bactrim, NSAID
On medication that decreases potassium level: Diuretics such as furosemide/Lasix, torsemide, hydrochlorothiazide, metolazone, bumetanide, chlorthalidone; fludrocortisone; albuterol
Very low urinary output (<30cc/hr)
Diet restrictions, fluid restriction, thickened liquids
Blood glucose, if elevated
Abnormal findings on cardiovascular, abdomen, or neurologic observations.
Assessment: I am concerned about: __________
Recommendations/Requests:
Labs: BMP/Chem8, magnesium
When to repeat the potassium level
Additional oral potassium if level is low
Kayexalate/Polystyrene sulfonate if level is high
Low potassium diet if level is high
Medication changes to prevent recurrence
Change fluid restriction orders
Other:
Clarify expectations for care, interventions, and illness course/prognosis. Repeat any telephone orders back to the provider to ensure that they are correct and complete
4. Implement Management Plan
Monitor vital signs every 8 hrs for 24 hours
Place on Intake & Output monitoring
Monitor meal acceptance
Place on 24-hour report
Dietician consult/assessment
Obtain lab results (if ordered), and notify medical as needed of significantly abnormal values in lab tests (refer to appropriate Situation)
Review status and plan of care with designated representative
