Question:

An infection found of both kidneys is considered a(n) _____ infection.

A. bilateral

B. unilateral

C. ipsilateral

D. contralateral

Anatomical Terms:

The key to this question lies in knowing what these anatomical terms refer to, particularly the lesser-known prefixes. The prefix 'ipsi-' means 'same'; an example is the right arm and the right leg are on the same side of the body. The prefix 'contra-' means 'opposite' but typically diagonal; the right arm and the left leg are contralateral to one another.

'

Answer and Explanation: 1

The answer is A. bilateral.

Bilateral means both sides, which is correct because the question says both kidneys. An infection in only one kidney would be unilateral. Ipsilateral and contralateral does not apply here, because those anatomical terms are in reference to one another (the way that the right arm is ipsilateral to the right leg). However, the kidneys are not referred to in this way because they are even, mirror images of one another, making them bilateral as opposed to ipsi- or contra-.
