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. A public health nurse is evaluating a program designed to reduce the incidence of sexually transmitted infections (STIs) among teenagers. Which outcome indicates that the program is successful?

• A. increased attendance at educational sessions on STIs
• B. higher rates of condom use among teenagers
• C. more teenagers seeking testing for STIs
• D. greater knowledge of STI prevention methods

Correct answer: B

Rationale: The correct answer is B: higher rates of condom use among teenagers. This outcome indicates that the teenagers are adopting safer sexual practices, which can effectively reduce the incidence of STIs. Increased attendance at educational sessions (Choice A) may show interest but does not directly reflect behavior change. More teenagers seeking testing for STIs (Choice C) indicates awareness but not necessarily prevention. Greater knowledge of STI prevention methods (Choice D) is valuable but does not guarantee behavioral change like increased condom use.

3. The nurse is developing a workshop on cancer prevention for a group of adults at a wellness bar. Which recommendation should the nurse include in the workshop?

• A. Know the four warning signs of cancer
• B. Maintain a healthy weight and exercise regularly
• C. Refrain from alcohol
• D. Obtain at least 6 to 10 hours of sleep per night

Correct answer: B

Rationale: Maintaining a healthy weight and exercising regularly are crucial recommendations in cancer prevention. These habits help reduce the risk of developing cancer by promoting overall health and reducing factors associated with cancer development. Knowing the warning signs of cancer (Choice A) is important for early detection but does not directly prevent cancer. While refraining from alcohol (Choice C) is beneficial for some cancers, it is not as universally applicable as maintaining a healthy weight and exercising. Getting adequate sleep (Choice D) is essential for overall health but is not as directly linked to cancer prevention as maintaining a healthy weight and regular exercise.

4. The nurse must delegate some aspects of a homebound client's care to a home health aide. Which intervention should the nurse delegate to the home health aide?

• A. evaluating a pressure sore
• B. applying a prosthetic device
• C. performing a sterile dressing change
• D. assessing the client's need for an elevated toilet seat

Correct answer: B

Rationale: The correct answer is B: applying a prosthetic device. Home health aides are trained and authorized to assist with the application and management of prosthetic devices for clients. Evaluating a pressure sore (choice A) requires clinical assessment and judgment typically performed by a licensed healthcare provider such as a nurse. Performing a sterile dressing change (choice C) involves aseptic technique and wound care skills that are usually performed by licensed healthcare professionals. Assessing the client's need for an elevated toilet seat (choice D) involves a level of assessment and decision-making that is beyond the scope of practice for a home health aide.

5. A public health nurse is planning a vaccination clinic for a rural community. Which vaccine should the nurse prioritize for adults in this area?

• A. hepatitis A
• B. influenza
• C. varicella
• D. measles, mumps, rubella (MMR)

Correct answer: B

Rationale: The correct answer is 'B: influenza.' Influenza vaccination is crucial for adults, particularly in rural areas where access to healthcare may be limited. Influenza can cause serious illness and complications, and vaccination helps protect individuals and prevent the spread of the virus. While vaccines for hepatitis A, varicella, and measles, mumps, rubella (MMR) are important, prioritizing influenza vaccination in this scenario is essential due to its seasonal prevalence and potential impact on public health. Hepatitis A and varicella vaccines are also important but may not be as immediately critical for this population. MMR vaccine is typically administered in childhood, so it is not the priority for adults in this scenario.
