Nursing Elites

1. A patient underwent fiberoptic colonoscopy 18 hours ago and presents to the emergency department with increasing abdominal pain, fever, and chills. Which of the following conditions poses the most immediate concern?

• A. Bowel perforation
• B. Viral gastroenteritis
• C. Colon cancer
• D. Diverticulitis

Correct answer: A

Rationale: The correct answer is bowel perforation. Bowel perforation is the most serious complication of fiberoptic colonoscopy, with signs such as progressive abdominal pain, fever, chills, and tachycardia indicating advancing peritonitis. Although colonoscopic perforation is rare (0.03% to 0.7% incidence), it can lead to high mortality and morbidity rates. Viral gastroenteritis (Choice B) typically presents with symptoms like diarrhea, nausea, vomiting, and abdominal cramps, but it is not the most immediate concern in this scenario. Colon cancer (Choice C) and diverticulitis (Choice D) are important conditions but are less likely to present acutely after colonoscopy compared to bowel perforation.

2. The nurse is preparing to care for an infant who has esophageal atresia with tracheoesophageal fistula. Surgery is scheduled to be performed in 1 hour. Intravenous fluids have been initiated, and a nasogastric (NG) tube has been inserted by the primary healthcare provider. The nurse plans care, knowing that which intervention is of highest priority during this preoperative period?

• A. Monitor the temperature.
• B. Monitor the blood pressure.
• C. Reposition the infant frequently.
• D. Aspirate the NG tube every 5 to 10 minutes.

Correct answer: D

Rationale: Esophageal atresia with tracheoesophageal fistula is a critical neonatal surgical emergency. The highest priority intervention during the preoperative period is to aspirate the NG tube every 5 to 10 minutes to keep the proximal pouch clear of secretions and prevent aspiration. This is crucial in reducing the risk of gastric secretions entering the lungs. Repositioning the infant frequently is not as critical as ensuring the NG tube is aspirated. Monitoring the temperature and blood pressure are important nursing interventions but are not the highest priority in this situation. It is essential to prioritize airway protection and prevent aspiration in this neonate undergoing urgent surgical intervention.

3. A client is in need of hemodialysis for end-stage renal failure. The physician has inserted an AV fistula. Which of the following nursing interventions is appropriate when caring for this access site?

• A. Assess for clotting in fistula tubing
• B. Apply a dressing over the fistula site
• C. Assess for a bruit or thrill at the site of the fistula
• D. Assess circulation proximal to the fistula site

Correct answer: A

Rationale: When caring for an AV fistula used for hemodialysis, it is important to assess for a bruit (a humming sound) or thrill (a vibrating sensation) at the site of the fistula. These indicate proper blood flow through the fistula, ensuring it is patent and suitable for hemodialysis. Assessing for clotting in fistula tubing (Choice A) is not a routine nursing intervention for AV fistulas. Applying a dressing over the fistula site (Choice B) is not necessary as the site needs to be accessible for hemodialysis. Assessing circulation proximal to the fistula site (Choice D) is important but not specific to caring for the access site of an AV fistula.

4. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

5. The nurse is caring for a 13-year-old following spinal fusion for scoliosis. Which of the following interventions is appropriate in the immediate post-operative period?

• A. Raise the head of the bed at least 30 degrees
• B. Encourage ambulation within 24 hours
• C. Maintain in a flat position, logrolling as needed
• D. Encourage leg contraction and relaxation after 48 hours

Correct answer: C

Rationale: In the immediate post-operative period following spinal fusion for scoliosis in a 13-year-old, it is important to maintain the patient in a flat position and perform logrolling as needed. This helps prevent injury to the surgical site and ensures proper spinal alignment. Raising the head of the bed at least 30 degrees is contraindicated as it can put strain on the surgical site. Encouraging ambulation within 24 hours may be appropriate in the recovery process but not in the immediate post-operative period. Encouraging leg contraction and relaxation after 48 hours may also be part of the rehabilitation process but is not a priority in the immediate post-operative period.
