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. A client is undergoing chemotherapy and is at risk for developing thrombocytopenia. What precaution should the nurse teach the client to minimize the risk of bleeding?

• A. Use a soft-bristled toothbrush.
• B. Engage in daily aerobic exercise.
• C. Take aspirin for headaches.
• D. Use an electric razor for shaving.

Correct answer: A

Rationale: Using a soft-bristled toothbrush is essential for clients at risk of thrombocytopenia to prevent gum bleeding, as their platelet counts may be low. Vigorous brushing with a hard-bristled toothbrush can injure the gums, leading to bleeding, which can be exacerbated in clients with low platelets. Therefore, advising the client to use a soft-bristled toothbrush is a crucial precaution to minimize the risk of bleeding.

3. A client with chronic kidney disease (CKD) has an arteriovenous (AV) fistula for hemodialysis. Which finding should the nurse report to the healthcare provider immediately?

• A. No bruit or thrill over the AV fistula.
• B. Redness at the site of the AV fistula.
• C. Client's complaint of pain at the AV fistula site.
• D. Swelling of the hand on the side of the AV fistula.

Correct answer: A

Rationale: In a client with a chronic kidney disease who has an arteriovenous (AV) fistula for hemodialysis, the absence of a bruit (a humming sound) or thrill (vibratory sensation) over the AV fistula indicates a potential occlusion. This finding suggests inadequate blood flow through the AV fistula, which is a critical issue requiring immediate intervention to prevent complications such as thrombosis or clot formation. Reporting this absence of bruit or thrill promptly to the healthcare provider is essential to ensure timely assessment and management to maintain vascular access for hemodialysis.

4. The nurse is caring for a client who is receiving chemotherapy. Which laboratory result indicates that the client is at risk for infection?

• A. Hemoglobin level of 12 g/dL.
• B. Platelet count of 150,000/mm3.
• C. White blood cell count of 2,000/mm3.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: C

Rationale: A white blood cell count of 2,000/mm3 is low and indicates leukopenia, which increases the client's risk for infection. Hemoglobin level and platelet count are not directly indicative of infection risk. Serum creatinine level is related to kidney function, not infection risk.

5. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.
