Which of the following hematological processes is most likely occurring in response to the infection? (Points : 0.4) * Proliferation of immature neutrophils|

|Question 2. As part of his diagnostic workup, a 77-year-old man’s nurse practitioner has ordered blood work that includes ferritin levels. The man is very interested in the details of his health care and is unfamiliar with ferritin and its role. He asks his nurse practitioner to explain the significance of it and the rationale for testing it. Which of the following explanations by the nurse practitioner is most accurate? (Points : 0.4) “Ferritin is the activated and usable form of iron that your red blood cells can use to transport oxygen.”|
“Ferritin is a stored form of iron that indirectly shows me whether you would benefit from iron pills.”
“Ferritin is a protein-iron complex that allows your red blood cells to make use of the iron that you consume in your diet.”
“Ferritin is the form of iron that is transported in your blood plasma to the red blood cells that need it.”

Which of the following statements best captures an aspect of the underlying rationale for the nurse practitioner’s suggestion? (Points : 0.4) Platelet aggregation can be precluded through inhibition of prostaglandin production by aspirin.|
Aspirin helps to inhibit adenosine disphosphate (ADP) action and minimizes platelet plug formation.
Aspirin can reduce unwanted platelet adhesion by inhibiting thromboxane A2 (TXA2) synthesis.
Aspirin inhibits the conversion of fibrinogen into fibrin and consequent platelet plug formation.
|Question 5. A 22-year-old female who adheres to a vegan diet has been diagnosed with iron-deficiency anemia. Which of the following components of her diagnostic blood work would be most likely to necessitate further investigation? (Points : 0.4) Decreased mean corpuscular volume (MCV)|
