Nursing Elites

1. A 68-year-old man with a history of diabetes, hypertension, and coronary artery disease (s/p coronary artery bypass graft two years ago) presents to the emergency room with fevers and left-sided abdominal pain. His physical examination reveals a temperature of 101.5°F, pulse 96, and blood pressure of 135/80. His abdomen is soft with moderate left lower quadrant tenderness. There is no rebound or guarding. Bowel sounds are present. A CT scan is done which reveals inflammation around an area of the left colon. The next step in his workup/management should be

• A. Antibiotic therapy with ciprofloxacin and metronidazole
• B. Referral for urgent colonoscopy
• C. Referral to a surgeon for immediate hemicolectomy
• D. Barium enema

Correct answer: A

Rationale: The patient's presentation is consistent with diverticulitis without evidence of perforation or abscess formation on CT scan. During acute infections, procedures like barium enema and colonoscopy should be avoided to prevent the risk of perforation. Urgent surgery is not indicated initially. The appropriate next step is to start antibiotic therapy aimed at gram-negative aerobes and anaerobes, such as ciprofloxacin and metronidazole, which are the initial treatment of choice for diverticulitis.

2. The nurse formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely etiology for this nursing diagnosis?

• A. Pain when coughing.
• B. Diminished cough effort.
• C. Thick, dry secretions.
• D. Excessive inflammation.

Correct answer: B

Rationale: The correct answer is B: Diminished cough effort. Clients with myasthenia gravis often experience muscle weakness, including respiratory muscles, which can lead to diminished cough effort. This weakness can result in ineffective airway clearance, putting the client at a high risk. Pain when coughing (choice A) is not directly related to the etiology of ineffective airway clearance in myasthenia gravis. While thick, dry secretions (choice C) and excessive inflammation (choice D) can contribute to airway clearance issues, the primary concern in myasthenia gravis is the muscle weakness affecting cough effort.

3. When assessing a client with a chest tube connected to suction, which observation indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation in the water seal chamber.
• D. Steady bubbling in the suction control chamber.

Correct answer: D

Rationale: Steady bubbling in the suction control chamber is the correct observation that indicates the chest tube is functioning properly. This steady bubbling signifies that the suction is actively maintaining the desired pressure level within the system, ensuring proper drainage and lung re-expansion. Continuous bubbling in the water seal chamber, intermittent bubbling in the suction control chamber, or no fluctuation in the water seal chamber are not indicative of optimal chest tube function and may require further assessment or intervention.

4. The patient described in the preceding question has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?

• A. She is at low risk for reinfection with H. pylori
• B. A positive serum IgG indicates that eradication of H. pylori was successful
• C. The urease breath test is an ideal test to document failure of eradication
• D. Dyspepsia typically worsens with H. pylori eradication

Correct answer: C

Rationale: Reinfection with H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. The serum IgG may remain positive indefinitely and cannot be used to determine failure of eradication; however, a decrease in quantitative IgG levels has been utilized to indicate treatment success. If available, either the stool antigen or urease breath test is ideal to document treatment failure due to their high sensitivity, specificity, and ease of performance. The relationship between dyspepsia and H. pylori is controversial, but generally, dyspepsia does not typically improve with H. pylori eradication.

5. What action should the nurse take to prevent tracheal tissue damage in a client with a tracheostomy?

• A. Secure the tracheostomy ties firmly.
• B. Change the tracheostomy tube daily.
• C. Use the minimal leak technique when inflating the cuff.
• D. Clean the stoma with hydrogen peroxide.

Correct answer: C

Rationale: To prevent tracheal tissue damage in a client with a tracheostomy, the nurse should use the minimal leak technique when inflating the cuff. This method helps avoid excessive pressure on the tracheal tissue, thereby reducing the risk of damage. Choice A is incorrect because securing the tracheostomy ties too tightly can cause pressure and tissue damage. Choice B is incorrect as changing the tracheostomy tube daily is not necessary unless there is a specific clinical indication. Choice D is incorrect as cleaning the stoma with hydrogen peroxide can irritate the skin and mucous membranes, potentially leading to damage.
