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)
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 C
Explanation
Choice A: This is not specifically related to the side effects of phenytoin.
Choice B: This is not directly related to the common side effects of phenytoin, which primarily affect the oral cavity.
Choice C: Phenytoin (Dilantin) is known to cause gingival hyperplasia (enlargement of the gums) as a common side effect. The nurse should regularly inspect the client's mouth to monitor for this adverse effect.
Choice D: This is not specifically relevant to monitoring for phenytoin's side effects.
Correct Answer is B
Explanation
Choice A: Comprehension of simple commands is an earlier developmental stage and not directly related to the infant's ability to search for a fallen toy.
Choice B: Exploration beyond caregiver presence is a key characteristic of the sensorimotor stage in Piaget's theory. During this stage, infants develop object permanence and begin to explore their environment independently.
Choice C: Visible or audible separation anxiety is common during the early stages of infancy and is not specific to the sensorimotor stage.
Choice D: The ability to place objects in a container is more related to later developmental stages when fine motor skills are more developed.
