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 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.

A. The consumption of protein products should come from lean meats, nuts, and dried beans. B. The consumption of fruit and/or vegetables should total between 4 to 6 servings. C. The consumption of dairy-based products should be eliminated from the diet. D. The consumption of bread products should be gluten-free.

Correct Answer is A

Explanation

Choice A: The client's statement reflects an understanding of the DASH diet's emphasis on lean meats, nuts, and dried beans as protein sources, which aligns with the principles of the diet.

Choice B: The DASH diet encourages the consumption of more than 4 to 6 servings of fruits and vegetables daily.

Choice C: The DASH diet does not eliminate dairy-based products but recommends choosing low-fat or fat-free options.

Choice D: The DASH diet does not focus on gluten-free foods but rather on overall dietary patterns that promote heart-healthy eating.
