Nursing Elites

1. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?

• A. Lactic acid
• B. Ammonia
• C. Albumin
• D. Lactase

Correct answer: B

Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.

2. Which goal of the client’s care should take priority during the first days of hospitalization for an exacerbation of ulcerative colitis?

• A. Promoting self-care and independence
• B. Managing diarrhea
• C. Maintaining adequate nutrition
• D. Promoting rest and comfort

Correct answer: B

Rationale: Managing diarrhea should take priority during the first days of hospitalization for an exacerbation of ulcerative colitis.

3. A client has just had surgery for colon cancer. Which of the following disorders might the client develop?

• A. Peritonitis
• B. Diverticulosis
• C. Partial bowel obstruction
• D. Complete bowel obstruction

Correct answer: C

Rationale: After surgery for colon cancer, the client may develop a partial bowel obstruction.

4. 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.

5. Which of the following symptoms best describes Murphy’s sign?

• A. Periumbilical ecchymosis exists
• B. On deep palpation and release, pain is elicited
• C. On deep inspiration, pain is elicited and breathing stops
• D. Abdominal muscles are tightened in anticipation of palpation

Correct answer: C

Rationale: Murphy's sign is described as pain elicited on deep inspiration when the examiner's fingers are placed under the right costal margin.
