Page 59 - ractice Exam Questions and rationales

A. anaphylaxis

B. toxicity

C. tinnitus

D. polyuria

Your response:
toxicity
Correct response:
toxicity
Rationale: In older adults, the rate of drug metabolism is decreased, and this increases the risk of
toxicity, which is the build-up of medication in the blood stream. Anaphylaxis is a serious
allergic reaction, tinnitus is ringing in the ears, and polyuria is a large amount of urine.
A female patient has come in for an ECG following a mastectomy. ECG electrodes should be
placed

A. three inches above the surgery site to avoid disruption of the site.

B. as close to the surgery site as possible without touching the site.

C. three inches lower than the surgery site in order to avoid disruption of the site.

D. in the intercostal spaces above the heart to avoid the surgical site.

Your response:
in the intercostal spaces above the heart to avoid the surgical site.
Correct response:
as close to the surgery site as possible without touching the site.
Rationale: If a female patient needing an ECG has had a mastectomy, the technician should
place the electrodes as close to the area they would normally be placed without touching the site
of surgery. If the technician were to place the electrodes three inches above or below the surgery
site, the electrodes would be too far away from the correct placement and therefore could give
false recordings.
