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 B
Explanation
Choice A: Introducing non-pharmacologic strategies for pain reduction is a valid intervention for managing pain in a client with sickle cell anemia. However, in this scenario, the client's laughter on the phone call may not necessarily indicate that the pain level is accurately reflected by the numerical rating. It is essential to consider the client's overall well-being and pain management plan.
Choice B: Allowing adequate privacy and time for the client's phone call is a considerate and appropriate action. It acknowledges the client's need for communication and emotional support, which can be important in managing pain.
Choice C: Documenting the concern of incongruent pain rating and behavior is a necessary step for the nurse to record the observation. However, it should not be the only action taken in response to the situation.
Choice D: Administering pain medication should be based on a comprehensive assessment of the client's pain and the healthcare provider's orders. While pain medication may be indicated for this client, it should not be administered solely based on the numerical pain rating without further assessment and consideration of the client's overall condition.
Correct Answer is ["A","B","C"]
Explanation
Choice A: Redness at the intravenous site may indicate infection or phlebitis, which are complications of TPN.
Choice B: Generalized nonpitting edema may indicate fluid overload, which can occur due to the high osmolarity of TPN.
Choice C: Frequent productive cough may indicate pulmonary edema or aspiration, which are also potential complications of TPN.
Choice D: Hypoactive bowel sounds in all 4 quadrants are not necessarily abnormal, as TPN bypasses the gastrointestinal tract.
Choice E: Urinary output greater than 30 mL per hour is within the normal range and indicates adequate renal function.
