Question 1 of 5
and tumor necrosis factor-alpha (TNF-α) during the acute phase response?
Correct Answer: A
Rationale: Macrophages are the primary cells responsible for producing tumor necrosis factor-alpha (TNF-α) during the acute phase response. TNF-α is a pro-inflammatory cytokine that plays a critical role in initiating and propagating the inflammatory response. Macrophages secrete TNF-α in response to infection, injury, or other inflammatory stimuli, contributing to the recruitment of immune cells and the activation of additional inflammatory pathways. In the context of the acute phase response, macrophages are key mediators of the immune response and play a crucial role in host defense mechanisms.

Question 3 of 5
A patient with chronic respiratory failure secondary to severe restrictive lung disease requires long-term oxygen therapy to maintain adequate oxygenation. Which of the following oxygen delivery devices is most appropriate for delivering continuous supplemental oxygen in this patient?
Correct Answer: D
Rationale: The most appropriate oxygen delivery device for a patient with chronic respiratory failure secondary to severe restrictive lung disease requiring continuous supplemental oxygen is a non-rebreather mask. A non-rebreather mask is designed to deliver high-flow oxygen and is typically used for short-term medical treatment in emergency situations or for critically ill patients. It is ideal for providing the highest concentration of oxygen available for inhalation, making it suitable for patients with severe hypoxemia.
Question 4 of 5
A patient presents with a history of recurrent nosebleeds, easy bruising, and gum bleeding. Laboratory tests reveal prolonged bleeding time and normal platelet count, PT, and aPTT. Which of the following conditions is most likely to cause these findings?
Correct Answer: A
Rationale: Von Willebrand disease is a hereditary bleeding disorder that results from a deficiency or dysfunction of von Willebrand factor (vWF), a protein that plays a key role in platelet adhesion and the initiation of primary hemostasis. The clinical manifestations of von Willebrand disease include recurrent mucocutaneous bleeding, such as nosebleeds, easy bruising, and gum bleeding. Laboratory findings typically show a prolonged bleeding time due to impaired platelet function, while platelet count, PT (prothrombin time), and aPTT (activated partial thromboplastin time) are usually normal. This distinguishes von Willebrand disease from other bleeding disorders such as hemophilia A (Factor VIII deficiency), which would show abnormal PT and aPTT due to deficiencies in specific clotting factors. Thrombocytopenia, on the other hand, would be characterized by a low platelet count
Question 5 of 5
A patient with a history of chronic liver disease presents with easy bruising and prolonged bleeding from minor cuts. Laboratory tests reveal prolonged PT and aPTT, and mixing studies show correction of coagulation times with normal plasma. Which of the following conditions is most likely to cause these findings?
Correct Answer: B
Rationale: Vitamin K is essential for the production of several clotting factors in the liver, including factors II, VII, IX, and X. In a patient with chronic liver disease, impaired liver function can lead to decreased synthesis of these clotting factors. As a result, there is an underlying deficiency of these clotting factors, leading to prolonged PT (prothrombin time) and aPTT (activated partial thromboplastin time). The mixing studies showing correction with normal plasma further support the diagnosis of a factor deficiency rather than an inhibitor, which helps in ruling out conditions like DIC or hemophilia.
