A nurse observes reddish-purple spots and areas of purple bruising on a newly admited patient. Which laboratory results support this assessment finding?
INR 0.9
Hematocrit 28%
WBC 4500
Platelets 60000
The Correct Answer is D
Choice A reason: An INR of 0.9 is within the normal range (0.8-1.2) and does not support the presence of bruising or bleeding disorders.
Choice B reason: A hematocrit level of 28% is below the normal range (36%-50% for women, 40%-54% for men), indicating anemia, but it does not directly explain bruising or petechiae.
Choice C reason: A WBC count of 4500 is within the normal range (4500-11000), suggesting that there is no active infection or leukocytosis that would explain the bruising.
Choice D reason: A platelet count of 60000 is below the normal range (150000-450000), which can lead to easy bruising and petechiae, supporting the nurse's observation.

Correct Answer is B
Explanation
Choice A reason: An embolic stroke is caused by an embolus traveling to the brain and blocking a blood vessel. The symptoms described do not specifically indicate an embolic stroke.
Choice B reason: A hemorrhagic stroke, which is bleeding within the brain, often presents with a sudden, severe headache, vomiting, and a change in consciousness, aligning with the symptoms described.
Choice C reason: A thrombotic stroke is caused by a thrombus forming in a blood vessel in the brain. While it can cause similar symptoms, the sudden severe headache is more characteristic of a hemorrhagic stroke.
Choice D reason: A transient ischemic attack (TIA) is a temporary blockage of blood flow to the brain. The symptoms usually resolve within minutes to hours and do not typically include a severe headache or vomiting.
Correct Answer is A
Explanation
Choice A reason: Stopping the transfusion immediately is the first and most critical action in response to signs of a possible transfusion reaction, which can be life-threatening.
Choice B reason: While informing the provider is a necessary step, it should come after stopping the transfusion to prevent further harm to the patient.
Choice C reason: Calling the lab is an appropriate action but not the first priority. The immediate concern is the patient's safety.
Choice D reason: Obtaining a urine specimen may be part of the diagnostic process for a transfusion reaction, but it is not the first action to take.
