Nursing Elites

1. Lactulose (Chronulac) is prescribed for a client with a diagnosis of hepatic encephalopathy. The nurse would determine that this medication has had a therapeutic effect if which of the following is noted?

• A. Increased red blood cell count
• B. Decreased serum ammonia level
• C. Increased protein level
• D. Decreased white blood cell level

Correct answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.

2. The client has had a new colostomy created 2 days earlier. The client is beginning to pass malodorous flatus from the stoma. The nurse interprets that

• A. This indicates inadequate preoperative bowel preparation.
• B. This is a normal, expected event.
• C. The client is experiencing early signs of ischemic bowel.
• D. The client should not have the nasogastric tube removed.

Correct answer: B

Rationale: As peristalsis returns following creation of a colostomy, the client begins to pass malodorous flatus. This indicates returning bowel function and is an expected event. Within 72 hours of surgery, the client should begin passing stool via the colostomy.

3. Which of the following symptoms is a client with colon cancer most likely to exhibit?

• A. A change in appetite
• B. A change in bowel habits
• C. An increase in body weight
• D. An increase in body temperature

Correct answer: B

Rationale: A change in bowel habits is the most common symptom of colon cancer.

4. Which of the following symptoms indicates diverticulosis?

• A. No symptoms exist
• B. Change in bowel habits
• C. Anorexia with low-grade fever
• D. Episodic, dull, or steady midabdominal pain

Correct answer: A

Rationale: Diverticulosis often has no symptoms and is usually found incidentally during tests for other conditions.

5. A nurse orientee is preparing to insert a nasogastric tube, and a nurse educator is observing the procedure. Which of the following supplies if obtained by the nurse orientee would indicate a need for further education regarding this procedure?

• A. Half-inch or one-inch tape
• B. Oil-soluble lubricant
• C. A glass of tap water with a straw
• D. A 50-mL catheter tip syringe

Correct answer: B

Rationale: Water-soluble lubricant is used to lubricate 3 to 4 inches of the tube at the insertion end. An oil lubricant is not used because if the tube accidentally goes into the bronchus, pneumonia can develop. Half-inch tape is used to secure the tube after the correct placement is verified. A 50-mL catheter tip syringe is used to aspirate gastric contents to confirm placement. The client will be asked to take a sip of water through a straw to help with the passage of the tube.
