Low potassium is an adverse reaction associated with taking:

Rationale

Hydrochlorothiazide is associated with low potassium levels.

Hydrochlorothiazide, a thiazide diuretic, promotes potassium excretion in urine, which can lead to hypokalemia (low potassium levels) as a common adverse effect. This mechanism is crucial for clinicians to monitor when prescribing this medication.

A (lisinopril) YOUR ANSWER

Lisinopril is an ACE inhibitor that typically does not cause low potassium levels; in fact, it can lead to hyperkalemia (high potassium levels) due to its effect on the renin-angiotensin-aldosterone system. Therefore, it is not associated with low potassium as an adverse reaction.

B (hydrochlorothiazide) CORRECT

As mentioned, hydrochlorothiazide increases potassium excretion through the kidneys, which can result in low potassium levels. This side effect is significant enough that potassium levels should be monitored regularly in patients taking this medication to prevent complications.

C (atenolol) YOUR ANSWER

Atenolol is a beta-blocker primarily used for hypertension and does not significantly affect potassium levels. While it may have other cardiovascular effects, it is not known to cause hypokalemia, making it an unlikely candidate for low potassium as an adverse reaction.

D (spironolactone) YOUR ANSWER

Spironolactone is a potassium-sparing diuretic, meaning it helps retain potassium in the body rather than causing its loss. It is often used to counteract the potassium-wasting effects of other diuretics, thus it is not associated with low potassium levels.

Conclusion

Hydrochlorothiazide stands out as the only medication among the options provided that is known to cause low potassium levels as an adverse reaction. Understanding the mechanisms of these medications is essential for safe prescribing practices, especially in managing electrolyte balance in patients.
