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. Which of the following associated disorders may the client with Crohn’s disease exhibit?

• A. Ankylosing spondylitis
• B. Colon cancer
• C. Malabsorption
• D. Lactase deficiency

Correct answer: A

Rationale: Clients with Crohn's disease may exhibit associated disorders such as ankylosing spondylitis, which is an inflammatory condition affecting the spine.

3. A client with which of the following conditions may be likely to develop rectal cancer?

• A. Adenomatous polyps
• B. Diverticulitis
• C. Hemorrhoids
• D. Peptic ulcer disease

Correct answer: A

Rationale: Adenomatous polyps are a known risk factor for the development of rectal cancer.

4. A client who has had gastrectomy is not producing sufficient intrinsic factor. The nurse interprets that the client has lost the ability to absorb cyanocobalamin (vitamin B12) in the

• A. Stomach.
• B. Small intestine.
• C. Large intestine.
• D. Colon.

Correct answer: B

Rationale: Intrinsic factor is produced in the stomach but is used to aid in the absorption of vitamin B12 in the small intestine. Vitamin B12 is not absorbed in the large intestine (options 3 and 4).

5. A client with liver dysfunction has low serum levels of thrombin. The nurse provides care, anticipating that this client is most at risk of

• A. Dehydration
• B. Malnutrition
• C. Bleeding
• D. Infection

Correct answer: C

Rationale: Thrombin is produced by the liver and is necessary for normal clotting. When a client with liver dysfunction has low serum levels of thrombin, they are at risk of bleeding due to impaired clotting mechanisms. Dehydration (choice A) is not directly related to low thrombin levels. Malnutrition (choice B) may impact overall health but is not the most immediate concern associated with low thrombin levels. Infection (choice D) is not directly related to the clotting function affected by low thrombin levels.
