PTCB Certified Pharmacy Technician (PTCE)MedicationsMedium
A pharmacy technician is reviewing a patient's medication profile and notices an order for 'potassium chloride 20 mEq PO daily.' Based on this order, what is the most likely reason the patient is taking this medication?
- ATo reduce stomach acid
- BTo correct hypokalemia
- CTo treat hypertension
- DTo prevent blood clots
Show answer & explanationAnswer & explanation
Correct answer: B. To correct hypokalemia
Potassium chloride is a common electrolyte supplement used to prevent or treat hypokalemia (low potassium levels). Hypokalemia can be caused by various factors, including diuretic use, vomiting, or diarrhea.
Why the other options are wrong
- A. Medications like proton pump inhibitors or H2 blockers are used to reduce stomach acid, not potassium chloride.
- C. While potassium can play a role in blood pressure regulation, potassium chloride supplements are not a primary treatment for hypertension.
- D. Potassium chloride has no role in preventing blood clots; anticoagulants like warfarin or heparin do.
Electrolyte Replacement
The administration of mineral salts to correct deficiencies in the body's electrolytes, which are essential for nerve and muscle function, hydration, and pH balance.
- Commonly replaced electrolytes include potassium, sodium, calcium, magnesium.
- Deficiencies can be caused by diuretics, vomiting, diarrhea, kidney disease.
- Important to monitor levels to avoid hyper- or hypo-states.
