Nursing Elites

1. Kevin has a history of peptic ulcer disease and vomits coffee-ground emesis. What does this indicate?

• A. He has fresh, active upper GI bleeding.
• B. He needs immediate saline gastric lavage.
• C. His gastric bleeding occurred 2 hours earlier.
• D. He needs a transfusion of packed RBCs.

Correct answer: C

Rationale: Coffee-ground emesis is a sign of upper gastrointestinal bleeding that occurred approximately 2 hours earlier. It results from the breakdown of blood in the stomach due to digestive enzymes, giving it a coffee-ground appearance. Choice A is incorrect because coffee-ground emesis indicates older, partially digested blood, not fresh active bleeding. Choice B is incorrect as gastric lavage is not indicated for coffee-ground emesis. Choice D is incorrect because a transfusion of packed RBCs is not the immediate management for this presentation.

2. 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.

3. Which of the following nursing measures would be inappropriate when caring for a client with a Cantor tube?

• A. Injecting 10 mL of air into the tube to facilitate drainage.
• B. Applying a water-soluble lubricant to the client's nares.
• C. Coiling extra tubing on the client's bed.
• D. Irrigating the tube with 50 mL of normal saline solution.

Correct answer: D

Rationale: Intestinal tubes are not irrigated. Injecting air into the tube, applying water-soluble lubricant, and coiling extra tubing are appropriate nursing measures.

4. The hospitalized client with gastroesophageal reflux disease is complaining of chest discomfort that feels like heartburn following a meal. After administering an ordered antacid, the nurse encourages the client to lie in which of the following positions?

• A. Supine with the head of the bed flat
• B. On the stomach with the head flat
• C. On the left side with the head of the bed elevated 30 degrees
• D. On the right side with the head of the bed elevated 30 degrees

Correct answer: C

Rationale: The discomfort of reflux is aggravated by positions that compress the abdomen and the stomach. Lying flat on the back (supine) or on the stomach (prone) after a meal can exacerbate symptoms. Similarly, lying on the right side can worsen reflux. The most appropriate position to alleviate discomfort in a client with gastroesophageal reflux disease is lying on the left side with the head of the bed elevated at a 30-degree angle. This position helps prevent the backflow of stomach contents into the esophagus, providing relief to the client.

5. Which of the following factors is believed to cause ulcerative colitis?

• A. Acidic diet
• B. Altered immunity
• C. Chronic constipation
• D. Emotional stress

Correct answer: B

Rationale: Ulcerative colitis is believed to be caused by an altered immune response in the gastrointestinal tract.
