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 client with a history of coronary artery disease is admitted with chest pain. Which assessment finding requires immediate intervention?

• A. Heart rate of 90 beats per minute.
• B. Respiratory rate of 20 breaths per minute.
• C. Blood pressure of 130/80 mm Hg.
• D. Chest pain radiating to the left arm.

Correct answer: D

Rationale: Chest pain radiating to the left arm is a classic symptom of a myocardial infarction (heart attack) in individuals with coronary artery disease. This finding indicates that the heart muscle may not be receiving adequate oxygen, which requires immediate intervention to prevent further damage or complications. The other assessment findings (heart rate of 90 beats per minute, respiratory rate of 20 breaths per minute, blood pressure of 130/80 mm Hg) are within normal limits and do not suggest an acute, life-threatening condition like myocardial infarction.

3. The public health nurse is called to investigate a report of several cases of chickenpox at a daycare center. The daycare worker states that five children have been sent home over the past two weeks with fever and itchy blisters. Which intervention should the nurse implement first?

• A. Validate that the children sent home did develop chickenpox
• B. Report the presence of a viral endemic at the daycare center
• C. Confirm the number of children with symptoms
• D. Determine how many people have been exposed

Correct answer: A

Rationale: Validating that the children sent home did develop chickenpox is the most crucial initial step for the nurse. This intervention ensures that the appropriate public health measures are implemented for the containment of chickenpox. Reporting a viral endemic or confirming the number of children with symptoms may be important but are secondary to confirming the diagnosis. Determining the number of people exposed comes after confirming the diagnosis to assess the extent of the outbreak and implement necessary control measures.

4. During a home visit, the nurse observes that a client with limited mobility has difficulty accessing the bathroom. What should the nurse do first?

• A. suggest the client install a bedside commode
• B. assist the client in modifying the home environment
• C. refer the client to an occupational therapist
• D. educate the client on mobility aids

Correct answer: A

Rationale: The correct answer is to suggest that the client installs a bedside commode. This option provides an immediate solution to the client's difficulty accessing the bathroom. While modifying the home environment (Choice B) and referring the client to an occupational therapist (Choice C) are important steps, suggesting a bedside commode addresses the immediate need efficiently. Educating the client on mobility aids (Choice D) can be beneficial but may not be the most urgent action required in this scenario.

5. A 56-year-old female client is receiving intracavitary radiation via a radium implant. Which nurse should be assigned to care for this client?

• A. A nurse who is pregnant.
• B. A nurse with Marfan syndrome who is postmenopausal.
• C. A nurse with a cold.
• D. A nurse who is lactating.

Correct answer: B

Rationale: A nurse with Marfan syndrome who is postmenopausal can safely care for the client because Marfan syndrome does not affect the ability to care for this client, and postmenopausal status minimizes the risk of radiation exposure affecting reproductive health. Choice A is incorrect because pregnancy increases the risk of radiation exposure to the fetus. Choice C is incorrect because a nurse with a cold may have a compromised immune system and should not be exposed to radiation therapy. Choice D is incorrect because lactation can increase the risk of radiation exposure to breast tissue.
