A nurse is caring for a patient admitted with symptoms of an anorectal infection; cultures indicate that the patient has a viral infection. The nurse should anticipate the administration of what drug?
- A. Acyclovir (Zovirax)
- B. Doxycycline (Vibramycin)
- C. Penicillin (penicillin G)
- D. Metronidazole (Flagyl)
Correct Answer: A
Rationale: Acyclovir (Zovirax) is often given to patients with viral anorectal infections. Doxycycline (Vibramycin) and penicillin (penicillin G) are drugs of choice for bacterial infections. Metronidazole (Flagyl) is used for other infections with a bacterial etiology; it is ineffective against viruses.

- A. Development of new hemorrhoids
- B. Abdominal bloating and flank pain
- C. Unexplained weight gain
- D. Change in bowel habits

A patients colorectal cancer has necessitated a hemicolectomy with the creation of a colostomy. In the 4 days since the surgery, the patient has been unwilling to look at the ostomy or participate in any aspects of ostomy care. What is the nurses most appropriate response to this observation?
- A. Ensure that the patient knows that he or she will be responsible for care after discharge.
- B. Reassure the patient that many people are fearful after the creation of an ostomy.
- C. Acknowledge the patients reluctance and initiate discussion of the factors underlying it.
- D. Arrange for the patient to be seen by a social worker or spiritual advisor.
Correct Answer: C
Rationale: If the patient is reluctant to participate in ostomy care, the nurse should attempt to dialogue about this with the patient and explore the factors that underlie it. It is presumptive to assume that the patients behavior is motivated by fear. Assessment must precede referrals and emphasizing the patients responsibilities may or may not motivate the patient.
A nurse is working with a patient who is learning to care for a continent ileostomy (Kock pouch). Following the initial period of healing, the nurse is teaching the patient how to independently empty the ileostomy. The nurse should teach the patient to do which of the following actions?
- A. Aim to eventually empty the pouch every 90 minutes.
- B. Avoid emptying the pouch until it is visibly full.
- C. Insert the catheter approximately 5 cm into the pouch.
- D. Aspirate the contents of the pouch using a 60 mL piston syringe.
Correct Answer: C
Rationale: To empty a Kock pouch, the catheter is gently inserted approximately 5 cm to the point of the valve or nipple. The length of time between drainage periods is gradually increased until the reservoir needs to be drained only every 4 to 6 hours and irrigated once each day. It is not appropriate to wait until the pouch is full, and this would not be visible. The contents of the pouch are not aspirated.
A patient with a diagnosis of colon cancer is 2 days postoperative following bowel resection and anastomosis. The nurse has planned the patients care in the knowledge of potential complications. What assessment should the nurse prioritize?
- A. Close monitoring of temperature
- B. Frequent abdominal auscultation
- C. Assessment of hemoglobin, hematocrit, and red blood cell levels
- D. Palpation of peripheral pulses and leg girth
Correct Answer: B
Rationale: After bowel surgery, it is important to frequently assess the abdomen, including bowel sounds and abdominal girth, to detect bowel obstruction. The resumption of bowel motility is a priority over each of the other listed assessments, even though each should be performed by the nurse.
A nurse is working with a patient who has chronic constipation. What should be included in patient teaching to promote normal bowel function?
- A. Use glycerin suppositories on a regular basis.
- B. Limit physical activity to promote bowel peristalsis.
- C. Consume high-residue, high-fiber foods.
- D. Resist the urge to defecate until the urge becomes intense.
Correct Answer: C
Rationale: Goals for the patient include restoring or maintaining a regular pattern of elimination by responding to the urge to defecate, ensuring adequate intake of fluids and high-fiber foods, learning about methods to avoid constipation, relieving anxiety about bowel elimination patterns, and avoiding complications. Ongoing use of soaps or pharmacologic aids should not be promoted, due to the risk of dependence. Increased mobility helps to maintain a regular pattern of elimination. The urge to defecate should be heeded.
