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 nurse is caring for a client with Addison's disease. Which finding requires immediate intervention?

• A. Hyperpigmentation of the skin.
• B. Low blood pressure.
• C. Nausea and vomiting.
• D. Hypoglycemia.

Correct answer: B

Rationale: Low blood pressure in a client with Addison's disease requires immediate intervention as it can indicate an Addisonian crisis, a life-threatening condition that necessitates prompt treatment. Hyperpigmentation of the skin is a characteristic finding in Addison's disease but does not require immediate intervention. Nausea and vomiting can be managed symptomatically in Addison's disease. While hypoglycemia needs attention, it is not the most critical finding requiring immediate intervention in this context.

3. In a community clinic where a recent case of tuberculosis (TB) has been diagnosed, which client who attended the clinic is at the highest risk for presenting with TB?

• A. a young adult who works as a daycare worker
• B. an adult who works in a corporate office
• C. an adolescent who attends the community high school
• D. an adult with a history of alcoholism and homelessness

Correct answer: D

Rationale: Individuals who are homeless and have a history of alcoholism are at the highest risk for presenting with TB in this scenario. Homeless individuals often live in crowded conditions with poor ventilation, increasing the likelihood of TB transmission. Additionally, alcoholism can weaken the immune system, making individuals more susceptible to developing TB. The other options, such as a daycare worker, an office worker, or a high school student, do not inherently carry the same level of risk factors for TB transmission as being homeless with a history of alcoholism.

4. 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.

5. When developing a presentation on injury prevention for high school students in a health education class, which topic is most important for the nurse to include?

• A. Sports-related injuries
• B. Substance abuse
• C. Seat belt safety
• D. Pregnancy prevention

Correct answer: C

Rationale: The correct answer is C: Seat belt safety. This topic is crucial as it can significantly reduce the risk of injury or death in car accidents, which is a common cause of severe injuries among high school students. While sports-related injuries, substance abuse, and pregnancy prevention are important topics, seat belt safety directly addresses a preventable cause of injuries that can have immediate life-saving effects.
