The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
a. "Do you take salicylates?"
b. "Are you taking any oral contraceptives?"
c. "Have you been prescribed antiseizure drugs?"
d. "How long have you taken antihypertensive drugs?"
ANS: A
Salicylates interfere with platelet function and can lead to petechiae and ecchymoses. Antiseizure drugs may cause anemia, but not clotting disorders or bleeding. Oral contraceptives increase a person's clotting risk. Antihypertensives do not usually cause problems with decreased clotting.
