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. A nurse is developing a plan of care for a client who will be returning to a nursing unit following a percutaneous transhephatic cholangiogram. The nurse includes which intervention in the postprocedure plan of care?

• A. Place a sandbag over the insertion site.
• B. Allow the client bathroom privileges only.
• C. Encourage fluid intake.
• D. Allow the client to sit in a chair for meals.

Correct answer: A

Rationale: Following this procedure, the nurse monitors the client’s vital signs closely for indications of hemorrhage and observes the needle insertion site for bleeding and bile leakage. A sandbag is placed over the insertion site to prevent bleeding. The client is maintained on bedrest, and oral intake is avoided in the immediate postprocedure period in case surgery is necessary to control hemorrhage of bile extravasation.

3. Before administering an intermittent tube feeding through a nasogastric tube, the nurse assesses for gastric residual. The nurse understands that this procedure is important to

• A. Confirm proper nasogastric tube placement.
• B. Observe gastric contents.
• C. Assess fluid and electrolyte status.
• D. Evaluate absorption of the last feeding.

Correct answer: D

Rationale: Evaluating the absorption of the last feeding is important because administration of a tube feeding to a full stomach could result in overdistention, thus predisposing the client to regurgitation and possible aspiration.

4. The nurse is caring for a client with chronic gastritis. The nurse monitors the client, knowing that this client is at risk for which of the following vitamin deficiencies?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin E

Correct answer: B

Rationale: Clients with chronic gastritis are at risk for Vitamin B12 deficiency due to impaired absorption.

5. 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.
