Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. The client with liver cirrhosis needs immediate intervention for which abnormal laboratory result?

• A. Prothrombin time (PT) of 14 seconds.
• B. Bilirubin of 1.2 mg/dL.
• C. Albumin of 4 g/dL.
• D. Ammonia level of 80 mcg/dL.

Correct answer: D

Rationale: An elevated ammonia level of 80 mcg/dL indicates hepatic encephalopathy, a serious complication of liver cirrhosis that requires immediate intervention. Ammonia is a neurotoxin that accumulates in the blood due to impaired liver function, leading to cognitive impairment and altered mental status. Monitoring and lowering ammonia levels are crucial in managing hepatic encephalopathy to prevent further neurological deterioration. Prothrombin time, bilirubin, and albumin levels are important parameters in assessing liver function and overall health status in clients with liver cirrhosis, but an elevated ammonia level poses an immediate threat to neurological function and warrants prompt attention.

3. To prepare a presentation on the greatest health concern facing the city, how should the health nurse begin collecting data?

• A. Review morbidity data for the city's population compiled by the Bureau of Vital Statistics
• B. Conduct a random telephone survey to determine the public's perception about health problems
• C. Survey major hospitals in the area to determine the most common reasons for admissions
• D. Call American Medical Association members to determine the most frequently treated diagnoses

Correct answer: A

Rationale: The correct answer is to review morbidity data for the city's population compiled by the Bureau of Vital Statistics. Morbidity data provides detailed and accurate information on the health issues prevalent in the city's population. This data is essential as it reflects actual health conditions rather than perceptions or specific hospital data. Conducting a telephone survey (choice B) may provide subjective opinions rather than objective data. Surveying hospitals (choice C) may only capture data on hospitalized cases and may not represent the entire population. Contacting American Medical Association members (choice D) may provide insights into medical treatments but may not reflect the overall health concerns of the city's population.

4. During a community health fair, the nurse conducts a blood pressure screening for a 60-year-old woman who has a blood pressure of 160/100 mm Hg. What should the nurse do first?

• A. Instruct the client to monitor her blood pressure at home
• B. Refer the client to her healthcare provider for further evaluation
• C. Educate the client on lifestyle changes to reduce blood pressure
• D. Recheck the blood pressure in 15 minutes

Correct answer: B

Rationale: When encountering a high blood pressure reading at a community health fair, it is essential for the nurse to refer the client to her healthcare provider for further evaluation. This step ensures that the client receives a comprehensive assessment, diagnosis, and appropriate management plan. In this scenario, it is crucial to prioritize professional evaluation over self-monitoring, lifestyle education, or immediate rechecking of the blood pressure. Referral to a healthcare provider allows for timely intervention and ongoing monitoring of the client's blood pressure to prevent potential complications.

5. The school nurse who is reviewing immunization records of students who will start kindergarten within the next month notes that most of the students have only received one dose of the measles, mumps, rubella (MMR) vaccine. Which intervention should the nurse implement?

• A. Note in the student records that the second dose of the MMR vaccine should be administered prior to entering first grade
• B. Send notices home with the children on the first day of class advising that MMR vaccine series must be completed
• C. Contact kindergarten parents to remind them that the second dose of MMR is due at the start of the school year
• D. Speak at the next parent-teacher association meeting to teach parents the benefits of immunizing their children

Correct answer: C

Rationale: The correct intervention for the school nurse is to contact kindergarten parents to remind them that the second dose of the MMR vaccine is due at the start of the school year. This approach directly addresses the issue of incomplete vaccination coverage and ensures that children receive the complete vaccination on time. Choice A is incorrect as it only notes the need for the second dose without actively engaging parents. Choice B is not as effective as directly contacting parents and may lead to delays in completing the vaccination series. Choice D, while promoting immunization, does not directly address the current situation of incomplete MMR vaccination among the kindergarten students.
