Nokea
A patient asks the nursing assistant for a bedpan. When the patient is finished, the nursing assistant notifies the nurse that the patient has bright red streaking of blood in the stool. What is this most likely a result of?
- A. Diet high in red meat
- B. Upper GI bleed
- C. Hemorrhoids
- D. Use of iron supplements
Correct Answer: C
Rationale: Lower rectal or anal bleeding is suspected if there is streaking of blood on the surface of the stool. Hemorrhoids are often a cause of anal bleeding since they occur in the rectum. Blood from an upper GI bleed would be dark rather than frank. Iron supplements make the stool dark, but not bloody and red meat consumption would not cause frank blood.

The nurse is caring for a patient who has a diagnosis of AIDS. Inspection of the patient's mouth reveals the new presence of white lesions on the patient's oral mucosa. What is the nurse's most appropriate response?
- A. Encourage the patient to gargle with salt water twice daily.
- B. Attempt to remove the lesions with a tongue depressor.
- C. Make a referral to the unit's dietitian.
- D. Inform the primary care provider of this finding.
Correct Answer: D
Rationale: The nurse should inform the primary care provider of this abnormal finding in the patient's oral cavity, since it necessitates medical treatment. It would be inappropriate to try to remove skin lesions from a patient's mouth and salt water will not resolve this problem, which is likely due to candidiasis. A dietitian referral is unnecessary.
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 nurse is assessing the abdomen of a patient just admitted to the unit with a suspected GI disease. Inspection reveals several diverse lesions on the patient's abdomen. How should the nurse best interpret this assessment finding?
- A. Abdominal lesions are usually due to age-related skin changes.
- B. Integumentary diseases often cause GI disorders.
- C. GI diseases often produce skin changes.
- D. The patient needs to be assessed for self-harm.
Correct Answer: C
Rationale: Abdominal lesions are of particular importance, because GI diseases often produce skin changes. Skin problems do not normally cause GI disorders. Age-related skin changes do not have a pronounced effect on the skin of the abdomen when compared to other skin surfaces. Self-harm is a less likely explanation for skin lesions on the abdomen.
A patient has been experiencing significant psychosocial stress in recent weeks. The nurse is aware of the hormonal effects of stress, including norepinephrine release. Release of this substance would have what effect on the patient's gastrointestinal function?
- A. Decreased motility
- B. Increased sphincter tone
- C. Increased enzyme release
- D. Inhibition of secretions
- E. Increased peristalsis
Correct Answer: A,B,D
Rationale: Norepinephrine generally decreases GI motility and secretions, but increases muscle tone of sphincters. Norepinephrine does not increase the release of enzymes.
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.
