Q.Assertion (A) : It is advised to restrict sodium in the diet of hypertensive patients. Reason (R) : Sodium restricted diets are given in oliguria. Codes :
Correct answer: Both (A) and (R) are true, but (R) is not the correct explanation for (A).
Explanation
It is advised to restrict sodium in diet of hypertensive patient because high sodium accumulate in the body and hold water to dilute sodium, this inturn increase amount of fluid and volume of blood in blood stream. Increased blood volume increases pressure on the blood vessels. The pressure can stiffen blood vessel leading to hypertension, heart failure and strokes. Oliguria is low urine output. Sodium require more water to dilute which cause water retention in body and lower the urine output. So sodium is restricted in diet of oliguria patient.
