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 C
Explanation
Choice A reason: Respiratory Acidosis is characterized by a low pH and a high PCO2, which is not the case here.
Choice B reason: Respiratory Alkalosis would involve a high pH and a low PCO2, which is not consistent with the patient's PCO2 level.
Choice C reason: Metabolic Alkalosis is indicated by a high pH and a high HCO3, which matches the patient's blood gas values.
Choice D reason: Metabolic Acidosis would show a low pH and a low HCO3, which is the opposite of this patient's presentation.
Correct Answer is D
Explanation
Choice A reason: Muscle dysfunction can be a consequence of COPD due to decreased activity levels, but it is not a risk factor for developing COPD.
Choice B reason: Poor nutrition can affect the overall health of individuals with COPD but is not a direct risk factor for developing the disease.
Choice C reason: Weight loss can occur in advanced stages of COPD due to increased energy expenditure from breathing difficulties, but it is not a risk factor for developing COPD.
Choice D reason: Increased risk for pneumonia is a direct risk associated with COPD, as the disease can compromise the respiratory system's ability to clear infections.
