A patient taking hydrochlorothiazide reports unusual muscle cramps and weakness. Which laboratory result should the nurse review?
Correct answer: A. Serum potassium level
- A. Serum potassium level
- B. Serum amylase level
- C. Platelet count
- D. Thyroid-stimulating hormone level
Explanation
Hydrochlorothiazide can increase urinary potassium loss, so hypokalaemia may cause cramps, weakness and dysrhythmias. Platelets, amylase and thyroid-stimulating hormone are not the usual first monitoring tests for this adverse effect.
