Nursing Elites

1. Why is it important to genotype HCV before initiating drug therapy?

• A. Side effects of nucleotide analogs
• B. Measures for improving the appetite
• C. Ways to increase activity and exercise
• D. Administering alpha-interferon (Intron A)

Correct answer: B

Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.

2. After performing an assessment of an infant with bladder exstrophy, the nurse prepares a plan of care. The nurse identifies which problem as the priority for the infant?

• A. Urinary incontinence
• B. Impaired tissue integrity
• C. Inability to suck and swallow
• D. Lack of knowledge about the disease (parents)

Correct answer: B

Rationale: In bladder exstrophy, the bladder is exposed and external to the body, leading to impaired tissue integrity related to the exposed bladder mucosa as the priority problem. Urinary incontinence is not a concern as the infant is not yet toilet trained. Inability to suck and swallow is unrelated to the disorder. While educating the parents about the condition is important, it is not the priority over addressing the immediate risk of impaired tissue integrity in the infant.

3. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

4. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

5. To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor

• A. bilirubin levels.
• B. ammonia levels.
• C. potassium levels.
• D. prothrombin time.

Correct answer: B

Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.
