Nursing Elites

1. 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.

2. When teaching a client postoperative breathing techniques with an incentive spirometer (IS), what should the nurse encourage the client to do to maintain sustained maximal inspiration?

• A. Exhale forcefully into the tubing for 3 to 5 seconds.
• B. Inspire deeply and slowly over 3 to 5 seconds.
• C. Breathe into the spirometer using normal breath volumes.
• D. Perform IS breathing exercises every 6 hours.

Correct answer: B

Rationale: To maintain sustained maximal inspiration when using an incentive spirometer, the client should be encouraged to inspire deeply and slowly over 3 to 5 seconds. This technique aids in achieving the goal of sustained maximal inspiration, which is essential for postoperative respiratory recovery.

3. A 65-year-old female client arrives in the emergency department with shortness of breath and chest pain. The nurse accidentally administers 10 mg of morphine sulfate instead of the prescribed 4 mg. Later, the client's respiratory rate is 10 breaths/minute, oxygen saturation is 98%, and she states her pain has subsided. What is the legal status of the nurse?

• A. The nurse is guilty of negligence and will be sued.
• B. The client would not be able to prove malpractice in court.
• C. The nurse is protected by the Good Samaritan Act.
• D. The healthcare provider should have given the morphine sulfate dose.

Correct answer: B

Rationale: The correct answer is B because, in this scenario, the client would not be able to prove malpractice in court. Despite the nurse administering a higher dose of morphine than prescribed, the client's respiratory rate, oxygen saturation, and pain relief indicate that no harm resulted from the error. Therefore, the client would not have legal grounds to pursue a malpractice case against the nurse.

4. A client with coronary artery disease (CAD) is prescribed atorvastatin (Lipitor). Which laboratory value requires immediate intervention?

• A. Total cholesterol of 180 mg/dL.
• B. Low-density lipoprotein (LDL) of 200 mg/dL.
• C. Triglycerides of 150 mg/dL.
• D. High-density lipoprotein (HDL) of 40 mg/dL.

Correct answer: B

Rationale: An LDL level of 200 mg/dL is significantly elevated and requires immediate intervention to reduce the risk of cardiovascular events in a client with coronary artery disease (CAD). High LDL levels contribute to the development and progression of atherosclerosis, which can lead to complications like heart attacks and strokes. Lowering LDL levels is a key goal in managing CAD and preventing further cardiovascular damage. Total cholesterol of 180 mg/dL, triglycerides of 150 mg/dL, and HDL of 40 mg/dL are within acceptable ranges and do not pose an immediate risk that necessitates urgent intervention.

5. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.
