Question Of The Day: Genitourinary Disorders

Q. Of the following findings in the client's history, which would be the least likely to have predisposed the client to renal calculi?

A. Having had several urinary tract infections in the past 2 years.
B. Having taken large doses of vitamin C over the past several years.
C. Drinking less than the recommended amount of milk.
D. Having been on prolonged bed rest after an accident the previous year.

Correct Answer: C

Explanation: A high, rather than low, milk intake predisposes to renal calculi formation, owing to the calcium in milk. Recurrent urinary tract infections are implicated in stone formation as certain bacteria promote stone formation. High daily doses of vitamins C are a risk factor because they can increase the citric acid level. Prolonged immobility is a risk factor for renal calculi because it causes calcium to be released into the bloodstream.
