Nursing Elites

1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

2. Following a CVA, the nurse assesses that a client developed dysphagia, hypoactive bowel sounds, and a firm, distended abdomen. Which prescription for the client should the nurse question?

• A. Continuous tube feeding at 65 ml/hr via gastrostomy.
• B. Total parenteral nutrition to be infused at 125 ml/hour.
• C. Nasogastric tube connected to low intermittent suction.
• D. Metoclopramide (Reglan) intermittent piggyback.

Correct answer: A

Rationale: In a client with dysphagia, hypoactive bowel sounds, and a firm, distended abdomen post-CVA, continuous tube feeding at 65 ml/hr via gastrostomy may exacerbate abdominal distension and hypoactive bowel sounds. This situation requires immediate assessment and reevaluation before continuing with the prescription.

3. After a client with ascites due to liver cirrhosis undergoes a paracentesis, what should the nurse do post-procedure?

• A. Encourage the client to drink plenty of fluids
• B. Monitor the client's blood pressure and heart rate
• C. Position the client flat on their back
• D. Administer a dose of furosemide

Correct answer: B

Rationale: Post-paracentesis, monitoring the client's blood pressure and heart rate is crucial as it helps in early detection of potential complications such as hypotension or bleeding. This close observation enables timely intervention and ensures the client's safety.

4. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

5. A client with heart failure is receiving intravenous furosemide (Lasix). Which assessment finding indicates that the medication is having the desired effect?

• A. Decreased peripheral edema.
• B. Elevated blood pressure.
• C. Increased heart rate.
• D. Decreased urine output.

Correct answer: A

Rationale: The correct answer is A: 'Decreased peripheral edema.' In a client with heart failure receiving furosemide, decreased peripheral edema indicates that the medication is effectively reducing fluid overload. Furosemide is a diuretic that helps the body eliminate excess fluid and salt through increased urine output, leading to a reduction in peripheral edema, which is a common symptom of heart failure. Monitoring and recognizing this improvement in edema are crucial in managing heart failure effectively.
