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 C

Explanation

Choice A: Salad greens with tomatoes do not provide a significant source of protein.

Choice B: One slice of cheese pizza may contain saturated fats from cheese and processed meats, so it may not be the best choice if the goal is to reduce saturated fat intake.

Choice C: A roasted turkey sandwich can be a good alternative source of protein without the same level of saturated fats found in hamburgers. Turkey is typically leaner than beef, and if prepared without excessive fats or sauces, it can be a healthier choice.

Choice D: Baked potato with low-fat butter is primarily a source of carbohydrates and fats but does not provide a significant source of protein.

A. Medication teaching concerning thyroid hormones B. Client and family referral to a hospice. C. Psychological counseling to address body image changes. D. Preoperative and postoperative teaching for adrenalectomy.

Correct Answer is D

Explanation

Choice A: Medication teaching concerning thyroid hormones is not directly related to the care of a client with pheochromocytoma. Pheochromocytoma primarily involves the adrenal glands and excessive secretion of catecholamines.

Choice B: Referral to a hospice is not a relevant goal for a client diagnosed with pheochromocytoma. Hospice care is typically provided for clients with advanced, life- limiting illnesses, and pheochromocytoma can often be treated or managed.

Choice C: Psychological counseling to address body image changes is not the primary goal for a client with pheochromocytoma. While psychological support may be beneficial, the primary focus should be on addressing the physiological effects and treatment of pheochromocytoma.

Choice D: Preoperative and postoperative teaching for adrenalectomy is the most relevant goal for a client with pheochromocytoma. Surgical removal of the tumor (adrenalectomy) is the primary treatment for pheochromocytoma, and education about the procedure, preparation, and postoperative care is essential to ensure a successful outcome.
