A client who was recently diagnosed with atrial fibrillation is receiving warfarin. To see the drug's effectiveness, which laboratory finding should the practical nurse (PN) review?

Complete blood count.

Serum troponin levels.

Creatinine clearance.

Prothrombin time (PT)

Answer and Explanation

The Correct Answer is D

Choice A: A complete blood count (CBC) is important for monitoring various aspects of the blood, including the number of red blood cells, white blood cells, and platelets. While important for assessing overall health, a CBC is not the primary laboratory finding used to assess the effectiveness of warfarin in managing atrial fibrillation.

Choice B: Serum troponin levels are typically measured to assess cardiac muscle damage, such as in myocardial infarction (heart attack). They are not the primary indicator for assessing the effectiveness of warfarin in atrial fibrillation.

Choice C: Creatinine clearance is a measure of kidney function and is not the primary laboratory finding used to evaluate the effectiveness of warfarin.

Choice D: Prothrombin time (PT) is the most relevant laboratory finding for monitoring the effectiveness of warfarin in clients with atrial fibrillation. Warfarin's therapeutic effect is primarily assessed through PT measurements, with the goal of maintaining the client's international normalized ratio (INR) within a specific target range to prevent excessive bleeding or clotting.

Correct Answer is D

Explanation

Choice A: The older female client who had a hip replacement yesterday and is notably pale with a hemoglobin of 10.5 g/dl likely needs attention, but the information provided does not indicate an urgent, life-threatening situation. Immediate intervention may not be necessary based on the information given.

Choice B: The adult client with osteomyelitis of the ankle who refuses an IV restart for antibiotics is concerning, but it does not represent an immediate life- threatening situation. The client's refusal should be addressed, but it may not require immediate attention.

Choice C: The elderly client with low back pain who removed pelvic traction and wants to go home may require assessment and intervention, but the information provided does not indicate an urgent, life-threatening situation. It may not be the first priority.

Choice D: The young adult client with a closed reduction of a fractured femur complaining of increasingly severe pain is the most concerning. Pain assessment and management are critical, and uncontrolled pain can lead to complications. This client should be attended to first to assess and address the pain.

A. Permanent life-style changes need to be made to promote safety in the home. B. Muscle tension is decreased with fine motor skill projects, so these activities should be encouraged C. Consistent discipline is needed to help the child control the movements. D. The chorea or movements are temporary and will eventually disappear.

Correct Answer is D

Explanation

Choice A: Permanent lifestyle changes may not be necessary for a child with rheumatic fever and associated chorea. Rheumatic fever is typically treated with antibiotics to clear the streptococcal infection and prevent further complications.

Choice B: Muscle tension is not typically decreased with fine motor skill projects, and encouraging such activities may not directly address the symptoms of chorea. Fine motor activities can be pursued if they are enjoyable for the child but should not be presented as a primary treatment.

Choice C: Consistent discipline is important for children but may not be the primary focus when addressing chorea associated with rheumatic fever. Discipline should be appropriate and consistent but should not be the primary intervention for chorea.

Choice D: The chorea or movements are temporary and will eventually disappear. This is the most accurate and reassuring information to provide to the parents. Chorea associated with rheumatic fever typically resolves over time with appropriate treatment, and the child is expected to recover fully.
