Nursing Elites

1. 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.

2. A client is admitted with a diagnosis of ulcerative colitis. Which of the following symptoms should the nurse expect the client to report when responding to questions about his bowel elimination pattern?

• A. Constipation.
• B. Bloody, diarrheal stools.
• C. Steatorrhea.
• D. Alternating periods of constipation and diarrhea.

Correct answer: B

Rationale: Diarrhea is the primary symptom of ulcerative colitis. It is profuse and severe; the client may pass as many as 15 to 20 watery stools per day. Stools may contain blood, mucus, and pus. The frequent diarrhea is often accompanied by anorexia and nausea. Constipation is not a sign or symptom of ulcerative colitis. Steatorrhea (fatty stools) is more typical of pancreatitis and cholecystitis. Alternating diarrhea and constipation is associated with irritable bowel syndrome.

3. Which of the following techniques would the nurse use first to determine if a nasogastric tube is positioned in the stomach?

• A. Aspirating with a syringe and observing for the return of gastric contents.
• B. Irrigating with normal saline and observing for the return of solution.
• C. Placing the tube's free end in water and observing for air bubbles.
• D. Instilling air and auscultating over the epigastric area for the presence of the tube.

Correct answer: A

Rationale: The initial way to determine if a nasogastric tube is in the stomach is to apply suction to the tube with a syringe and observe for the return of stomach contents. Then the pH of the aspirate can be measured. This is the method of choice. One would not irrigate until tube placement is confirmed. Observing for air bubbles when the free end of the tube is placed under water is an unacceptable, unsafe method of determining tube placement. Another method is to instill air into the tube with a syringe while auscultating over the epigastric area. Hearing the air enter the stomach helps ensure proper placement, but the method is not foolproof and is no longer considered an effective or preferred way to determine placement.

4. After a subtotal gastrectomy, care of the client’s nasogastric tube and drainage system should include which of the following nursing interventions?

• A. Irrigate the tube with 30 ml of sterile water every hour, if needed.
• B. Reposition the tube if it is not draining well
• C. Monitor the client for N/V, and abdominal distention
• D. Turn the machine to high suction of the drainage is sluggish on low suction.

Correct answer: C

Rationale: Monitoring the client for nausea, vomiting, and abdominal distention is crucial for ensuring proper functioning of the nasogastric tube and drainage system.

5. The client being treated for esophageal varices has a Sengstaken-Blakemore tube inserted to control the bleeding. The most important assessment is for the nurse to:

• A. Check that the hemostat is on the bedside
• B. Monitor IV fluids for the shift
• C. Regularly assess respiratory status
• D. Check that the balloon is deflated on a regular basis

Correct answer: C

Rationale: Regularly assessing respiratory status is crucial when a Sengstaken-Blakemore tube is inserted to control bleeding in esophageal varices.
