Question 2 of 5
A nurse is caring for a client with peripheral artery disease who has an arterial ulcer. Which of the following best describes the mechanism for developing the clinical problem?
Correct Answer: B

Question 3 of 5
A nurse is reviewing laboratory data from a client who has pulmonary embolism and is receiving IV heparin. Which of the following findings should the nurse report to the provider?
Correct Answer: D
Rationale: A low platelet count (74,000/mm³) may indicate heparin-induced thrombocytopenia, a serious complication of heparin therapy that requires immediate reporting.
