Your response:
recently ingested hot or cold food or beverages.
Correct response:
recently ingested hot or cold food or beverages.
Rationale: An oral temperature reading can be falsely elevated or decreased if a patient ingests
hot or cold food or drink close to the time the temperature is taken. Prescribed medications
would not cause the reading to be inaccurate (though they may help accurately reduce the fever
if they include antipyretics). Neither having a fever within the last 24 hours nor trouble
swallowing should have any bearing on the accuracy of an oral temperature reading, provided it
is taken correctly.
When performing a capillary puncture on an infant, the medical assistant understands the lateral
heel is the proper site for collection due to which of the following?

A. The tissue layers on the finger are more susceptible to permanent nerve damage.

B. The finger produces a slower flow of blood, making it more difficult to obtain a
specimen.

C. The small amount of tissue between the skin and bone in the finger makes an injury to
the bone likely.

D. The blood in the fingertip has been found to contain a higher concentration of
hemoglobin than the heel.

Your response:
The small amount of tissue between the skin and bone in the finger makes an injury to the bone
likely.
Correct response:
The small amount of tissue between the skin and bone in the finger makes an injury to the bone
likely.
Rationale: Heel sticks are easily accessible and minimally invasive for capillary puncture.
Fingers of infants are too small to tolerate the trauma of skin puncture.
