Module 1 assignment: Electrolyte abnormalities
Identify an electrolyte from the list below. Using references that you may already have identified, indicate conditions caused by too much or too little of that electrolyte. In the first column with the identified electrolyte, write the normal lab value range and cause of imbalance. After identifying the hyper- and hypo- conditions, also identify treatment of those conditions.
· Potassium
· Sodium
· Magnesium
· Phosphorus
· Chloride
· Calcium
Format: Use at least one scholarly source to support your findings. Examples of scholarly sources include academic journals, textbooks, reference texts, and CINAHL nursing guides. Be sure to cite your sources in-text and on a References page using APA format.

Electrolyte Selected: Potassium (K+)
Normal Range and Causes of Imbalance
The normal serum potassium level ranges from 3.5 to 5.0 mEq/L (Braddy & Winslow, 2020). Imbalances in potassium levels can be life-threatening, affecting cardiac and neuromuscular functions. Hyperkalemia, an elevated potassium level, occurs when serum potassium exceeds 5.0 mEq/L, while hypokalemia, a decreased level below 3.5 mEq/L, can result from various causes.
Causes of hyperkalemia include:
- Renal failure or impaired kidney function
- Use of potassium-sparing diuretics
- Excessive potassium intake
Causes of hypokalemia include:
- Diuretic use, especially loop and thiazide diuretics
- Inadequate dietary intake
- Gastrointestinal losses such as vomiting and diarrhea
Signs and Symptoms of Electrolyte Imbalances
Hyperkalemia often presents with muscle weakness, fatigue, palpitations, and alterations in cardiac rhythm such as arrhythmias, which can be detected through EKG changes. Severe hyperkalemia can lead to cardiac arrest if not promptly treated (Kumar & Clark, 2018).
Hypokalemia manifests through muscle cramps, weakness, fatigue, irregular heart rhythms, and in severe cases, paralysis. EKG changes such as flattened T waves and prominent U waves are indicative of hypokalemia (Braddy & Winslow, 2020).
Treatment of Hyper- and Hypokalemia
Management of hyperkalemia includes reducing potassium intake, administering medications such as sodium polystyrene sulfonate to promote potassium excretion, intravenous calcium to stabilize cardiac membranes, and in severe cases, dialysis (Weinhouse et al., 2019). Conversely, hypokalemia treatment involves potassium supplementation either orally or intravenously, addressing underlying causes such as discontinuing diuretics or treating gastrointestinal losses (Kumar & Clark, 2018). Close monitoring of serum potassium levels is vital during therapy to prevent complications.
