Nursing Elites

1. Which of the following measures should the nurse focus on for the client with esophageal varices?

• A. Recognizing hemorrhage
• B. Controlling blood pressure
• C. Encouraging nutritional intake
• D. Teaching the client about varices

Correct answer: A

Rationale: The primary focus for a client with esophageal varices is recognizing hemorrhage because these varices can rupture and cause significant bleeding.

2. The nurse is teaching the client how to perform a colostomy irrigation. To enhance the effectiveness of the irrigation and fecal returns, what measure should the nurse instruct the client to do?

• A. Increase fluid intake
• B. Reduce the amount of irrigation solution
• C. Perform the irrigation in the evening
• D. Place heat on the abdomen

Correct answer: A

Rationale: Increasing fluid intake helps to enhance the effectiveness of colostomy irrigation by softening the stool and promoting better fecal return.

3. The nurse aspirates 40 mL of undigested formula from the client’s nasogastric tube. Before administering an intermittent tube feeding, the nurse understands that the 40 mL of gastric aspirate should be

• A. Discarded properly and recorded as output on the client’s intake and output record.
• B. Poured into the nasogastric tube through a syringe with the plunger removed.
• C. Mixed with the formula and poured into the nasogastric tube through a syringe with the plunger removed.
• D. Diluted with water and injected into the nasogastric tube by putting pressure on the plunger.

Correct answer: B

Rationale: After checking the residual feeding contents, the gastric contents are reinstalled into the stomach by removing the syringe bulb or plunger and pouring the gastric contents into the syringe and through the nasogastric tube. Gastric contents should be reinstalled to maintain the client’s electrolyte balance. The gastric contents should be poured into the nasogastric tube through a syringe without a plunger and not injected by putting pressure on the plunger. Gastric contents do not need to be mixed with water or should the contents be discarded.

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. The most important pathophysiologic factor contributing to the formation of esophageal varices is:

• A. Decreased prothrombin formation
• B. Decreased albumin formation by the liver
• C. Portal hypertension
• D. Increased central venous pressure

Correct answer: C

Rationale: Portal hypertension is the most important pathophysiologic factor contributing to the formation of esophageal varices.
