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 A
Explanation
Choice A reason: Hypertension is a well-known modifiable risk factor for stroke. Controlling blood pressure can significantly reduce the risk of having a stroke.
Choice B reason: A history of sickle cell disease is a genetic condition and is not considered a modifiable risk factor.
Choice C reason: Having a parent with cardiovascular disease is a non-modifiable risk factor as it is related to genetics.
Choice D reason: Age is a non-modifiable risk factor for stroke. The risk of stroke increases with age.
Correct Answer is B
Explanation
Choice A reason: Inadequate retention of serum sodium is not typically associated with anemia in chronic renal failure.
Choice B reason: Inadequate production of erythropoietin is the correct answer because the kidneys produce erythropoietin, which stimulates the bone marrow to produce red blood cells. In chronic renal failure, the kidneys cannot produce enough erythropoietin, leading to anemia.
Choice C reason: While blood loss in the urine can occur, it is not the primary cause of anemia in chronic renal failure.
Choice D reason: Renal desensitization to Vitamin D affects bone health and calcium levels but is not the primary cause of anemia in chronic renal failure.
