A client will be having a total colectomy in 4 days. The client does not have an obstruction. What does the nurse anticipate instructing the client about doing prior to the surgery to prepare the bowel?
- A. Instructing the client about dietary restrictions and lavage agents
- B. Making sure the client drinks 2 L of fluids prior to the procedure
- C. Instructing the client to have no food except clear liquids for 4 days
- D. There will be no special preparation, and the client may eat until midnight the night prior to surgery.
Correct Answer: A
Rationale: Cleansing of the bowel before surgery is carried out using dietary restriction in combination with laxative or lavage agents, depending on the client's condition (i.e., presence or absence of obstruction) and according to the surgeon's preference. There are no benefits to the client drinking 2 L of fluids prior to the procedure or taking in only clear liquids for 4 days.

The nurse is instructing a client with an ileostomy on appliance and changing it. What statement made by the client demonstrates the client understands using a new appliance for the first time?
- A. I will patch test it first on nonirritated skin at the inner side of my forearm.'
- B. I can expect the new appliance to sting or itch for the first 24 hours.'
- C. When changing the appliance and faceplate, I should scrub vigorously to remove all debris.'
- D. I should change the faceplate every 8 hours.'
Correct Answer: A
Rationale: When using a new adhesive product, the client should patch test it first on nonirritated skin at the inner aspect of the forearm. The most common causes of discomfort are reactions to the adhesive or solvent used to remove it or irritation from leaking fecal drainage. In such cases, the client may experience stinging, tingling, or itching immediately after an appliance change. If a sensation is prolonged or intensified, the client should remove the appliance regardless of whether it has been on for 1 hour or several days. The client should avoid rubbing, which may further irritate skin. If the faceplate is changed too frequently, skin around the stoma may become raw and excoriated secondary to removal of protective layers of epithelium with the faceplate.

Correct Answer: D
Rationale: Karaya paste, which becomes gelatinous when in contact with moisture, is commonly used in place of an adhesive. Karaya paste promotes adhesion of the ostomy appliance.

A client who is scheduled for an ileostomy surgery and been taking corticosteroids is instructed to taper the drug, eventually discontinuing it. The nurse would monitor this client for which of the following?
- A. Cerebral anoxia
- B. Cardiac dysrhythmias
- C. Hypothyroidism
- D. Adrenal insufficiency
Correct Answer: D
Rationale: Adrenal crisis is potentially life-threatening and may result from the abrupt withdrawal of corticosteroids. Therefore, the nurse should closely monitor a client who is scheduled for an ileostomy surgery for adrenal insufficiency, resulting from corticosteroid withdrawal. Withdrawal of corticosteroids does not cause cerebral anoxia, cardiac dysrhythmias, or hypothyroidism.
A client is to have a total colectomy and has been on prednisone for 6 months for the treatment of Crohn disease. What medication does the nurse anticipate administering in the preoperative phase to prevent adrenal crisis?
- A. Intravenous hydrocortisone
- B. Intravenous antibiotics
- C. Blood transfusion
- D. A low-molecular-weight heparin
Correct Answer: A
Rationale: A preoperative 'stress' IV steroid (e.g., hydrocortisone) is given to clients who have been on prednisone within the previous 6 months to prevent adrenal crisis. Antibiotics, blood transfusions, and low-molecular-weight heparin are not typically used to prevent adrenal crisis in this context.
