In a client with mitral regurgitation the nurse would expect to see which of the following signs and symptoms?

Correct Answer: C

Rationale: Mitral regurgitation causes blood to flow back into the left atrium, leading to pulmonary congestion and exertional dyspnea (shortness of breath with activity). Crushing chest pain is more typical of myocardial infarction, and elevated WBC suggests infection, not regurgitation directly.

Correct Answer: C

Rationale: Excessive alcohol increases warfarin's anticoagulation effect by impairing liver metabolism, raising bleeding risk. INR increases (not decreases, B), and vitamin K absorption (D) is unaffected; A is the opposite effect.

Correct Answer: A

Rationale: The heart is situated in the thoracic cavity, specifically within the mediastinum, between the lungs. The abdominal cavity (Choice B) contains organs like the stomach and liver, the pelvic cavity (Choice C) houses reproductive and urinary organs, and the cranial cavity (Choice D) contains the brain. Only the thoracic cavity correctly identifies the heart’s location.

Correct Answer: C

Rationale: Coagulation (Choice C) specifically refers to the process of blood clot formation, where blood transforms from a liquid to a gel-like state through a cascade of clotting factors. Hemostasis (Choice A) is the broader process of stopping bleeding, which includes coagulation but also vessel constriction. Thrombolysis (Choice B) is clot dissolution, and fibrinolysis (Choice D) is the breakdown of fibrin in clots—both opposites of formation. Choice C is the precise term.
