Nursing Elites

1. A client is suspected of being poisoned and presents with symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth. The nurse should consider these findings consistent with which potential bioterrorism agent?

• A. ricin
• B. botulism toxin
• C. sulfur mustard
• D. yersinia pestis

Correct answer: B

Rationale: The correct answer is B: botulism toxin. The symptoms described, including symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth, are classic manifestations of botulism, which is caused by a toxin produced by Clostridium botulinum. This toxin affects the nervous system, leading to muscle weakness and paralysis. Choice A, ricin, typically presents with gastrointestinal symptoms and organ failure. Choice C, sulfur mustard, causes blistering skin and respiratory issues. Choice D, yersinia pestis, is associated with the plague and presents with fever, chills, weakness, and swollen lymph nodes.

2. A public health nurse is working with a community to improve vaccination rates. Which intervention is most likely to be effective?

• A. Setting up vaccination clinics in accessible locations
• B. Distributing flyers with information about vaccines
• C. Offering incentives for getting vaccinated
• D. Partnering with local businesses to promote vaccination

Correct answer: A

Rationale: Setting up vaccination clinics in accessible locations is the most effective intervention to improve vaccination rates. This intervention ensures easy access to vaccination services for community members, removing barriers such as transportation or time constraints. Distributing flyers (Choice B) may increase awareness but may not directly address access issues. Offering incentives (Choice C) might temporarily boost vaccination rates but may not lead to sustained behavior change. Partnering with local businesses (Choice D) could be beneficial for promotion but may not directly impact vaccination accessibility.

3. Community health nurses are particularly concerned with the source of communicable diseases such as hepatitis A. Which group of individuals have a higher risk of contracting that type of hepatitis?

• A. IV drug users who share needles
• B. low-income families living in cramped quarters
• C. those who have recently received a blood transfusion
• D. sexually active persons with multiple partners

Correct answer: B

Rationale: The correct answer is B. Hepatitis A is often spread through close personal contact and poor sanitary conditions, which are more common in low-income, cramped living situations. IV drug users sharing needles are at higher risk of hepatitis B and C due to bloodborne transmission. Those who have recently received a blood transfusion are at risk of hepatitis C or other bloodborne infections. Sexually active persons with multiple partners are at risk of hepatitis B, which can be transmitted through sexual contact.

4. The nurse is assessing a client with pneumonia who is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client's respiratory rate is 20 breaths per minute.
• B. The client's arterial blood gases show a pH of 7.35.
• C. The client's oxygen saturation is 92%.
• D. The client's breath sounds are clear.

Correct answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

5. 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.
