Nursing Elites

1. 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.

2. 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.

3. 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.

4. A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?

• A. Increase urine output
• B. Reduce blood sugar levels
• C. Decrease urine output
• D. Lower blood pressure

Correct answer: C

Rationale: Desmopressin is prescribed to decrease urine output in patients with diabetes insipidus. It works by increasing water reabsorption in the kidneys, helping to control fluid balance in the body.

5. The client was recently diagnosed with chronic gastritis. What health practice should the nurse address when teaching the client to limit exacerbations of the disease?

• A. Perform 15 minutes of physical activity at least three times per week.
• B. Avoid taking aspirin to treat pain or fever.
• C. Take multivitamins as prescribed and eat organic foods whenever possible.
• D. Maintain a healthy body weight.

Correct answer: B

Rationale: The correct answer is B. Avoiding aspirin is crucial in managing chronic gastritis as it can further irritate the stomach lining, leading to exacerbations of the condition. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that can increase stomach acid production, potentially worsening gastritis symptoms. Therefore, the nurse should educate the client on using alternative pain or fever relief methods that are less likely to aggravate gastritis, such as acetaminophen.
