Diuretics and Adverse Effects Explained

This question concerns the adverse effects of high ceiling diuretics and the underlying reason. Let's analyze the Assertion (A) and Reason (R).

Assertion A Analysis

Assertion A states that high ceiling diuretics commonly cause adverse effects such as weakness, fatigue, and muscle cramps.

• High ceiling diuretics, like furosemide, are potent diuretics.
• A known side effect profile includes electrolyte disturbances.
• Symptoms like weakness, fatigue, and muscle cramps are characteristic of electrolyte imbalances, particularly low potassium levels.
• Therefore, Assertion A is factually correct.

Reason R Analysis

Reason R proposes that these diuretics induce hypokalemia (low potassium levels).

• High ceiling diuretics increase the excretion of sodium, chloride, and water from the kidneys.
• This process also significantly increases the excretion of potassium ions, especially in the distal tubule.
• This increased potassium loss leads to hypokalemia.
• Therefore, Reason R is also factually correct.

Relationship Between Assertion A and Reason R

We need to determine if Reason R correctly explains Assertion A.

• Hypokalemia, the condition described in Reason R, is a direct cause of the symptoms mentioned in Assertion A (weakness, fatigue, muscle cramps).
• The mechanism is that low potassium levels affect nerve and muscle function.
• Thus, the hypokalemia induced by high ceiling diuretics is the direct reason for the weakness, fatigue, and muscle cramps.
• Reason R provides the correct physiological explanation for Assertion A.

Based on this analysis, both statements are correct, and Reason R is the correct explanation for Assertion A.
