When preparing the patient for an exercise tolerance test (treadmill), the nurse should:

A patient having an exercise tolerance test is kept NPO except for water, for 4 hours until after the test. The nurse should never hold the patient’s heart medications before this test.
A patient has just had a liver biopsy. Immediately following this procedure, the nurse should:
tell the patient to avoid coughing.
coughing may cause increased intra-abdominal pressure.
After a bone scan, the nurse assesses a hematoma at the injection site of the dye. The nurse should apply ______ soaks or compresses.

ANS:
2, 6
When collecting a stool specimen for a guaiac (occult blood in stool), the nurse should take a specimen from _____ different parts of the stool.
