- B. Below the right nipple
- C. Left groin area

A patient will be undergoing abdominal computed tomography (CT) with contrast. The nurse has administered IV sodium bicarbonate and oral acetylcysteine (Mucomyst) before the study as ordered. What would indicate that these medications have had the desired therapeutic effect?
- A. The patient's BUN and creatinine levels are within reference range following the CT.
- B. The CT yields high-quality images.
- C. The patient's electrolytes are stable in the 48 hours following the CT.
- D. The patient's intake and output are in balance on the day after the CT.
Correct Answer: A
Rationale: Both sodium bicarbonate and Mucomyst are free radical scavengers that sequester the contrast byproducts that are destructive to renal cells. Kidney damage would be evident by increased BUN and creatinine levels. These medications are unrelated to electrolyte or fluid balance and they play no role in the results of the CT.
The nurse is preparing to perform a patient's abdominal assessment. What examination sequence should the nurse follow?
- A. Inspection, auscultation, percussion, and palpation
- B. Inspection, palpation, auscultation, and percussion
- C. Inspection, percussion, palpation, and auscultation
- D. Inspection, palpation, percussion, and auscultation
Correct Answer: A
Rationale: When performing a focused assessment of the patient's abdomen, auscultation should always precede percussion and palpation because they may alter bowel sounds. The traditional sequence for all other focused assessments is inspection, palpation, percussion, and auscultation.
A patient has come to the outpatient radiology department for diagnostic testing. Which of the following diagnostic procedures will allow the care team to evaluate and remove polyps?
- A. Colonoscopy
- B. Barium enema
- C. ERCP
- D. Upper gastrointestinal fibroscopy
Correct Answer: A
Rationale: During colonoscopy, tissue biopsies can be obtained as needed, and polyps can be removed and evaluated. This is not possible during a barium enema, ERCP, or gastroscopy.
Probably the most widely used in-office or at-home occult blood test is the Hemoccult II. The patient has come to the clinic because he thinks there is blood in his stool. When you reviewed his medications, you noted he is on antihypertensive drugs and NSAIDs for early arthritic pain. You are sending the patient home with the supplies necessary to perform 2 hemoccult tests on his stool and mail the samples back to the clinic. What instruction would you give this patient?
- A. Take all your medications as usual.
- B. Take all your medications except the antihypertensive medications.
- C. Don't eat highly acidic foods 72 hours before you start the test.
- D. Avoid vitamin C for 72 hours before you start the test.
Correct Answer: D
Rationale: Red meats, aspirin, nonsteroidal anti-inflammatory drugs, turnips, and horseradish should be avoided for 72 hours prior to the study, because they may cause a false-positive result. Also, ingestion of vitamin C from supplements or foods can cause a false-negative result. Acidic foods do not need to be avoided.
A nurse in a stroke rehabilitation facility recognizes that the brain regulates swallowing. Damage to what area of the brain will most affect the patient's ability to swallow?
- A. Temporal lobe
- B. Medulla oblongata
- C. Cerebellum
- D. Pons
Correct Answer: B
Rationale: Swallowing is a voluntary act that is regulated by a swallowing center in the medulla oblongata of the central nervous system. Swallowing is not regulated by the temporal lobe, cerebellum, or pons.
