Free CV-BC Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

Pathophysiology knowledge and rapid assessment under Assessment and Diagnosis require recognition of the classic features of acute aortic dissection: abrupt severe tearing or ripping pain, pulse or blood-pressure differentials, and possible acute aortic regurgitation. This presentation, particularly with signs of ascending aortic involvement, constitutes a surgical emergency. Immediate suspicion drives urgent advanced imaging and controlled blood-pressure reduction while avoiding therapies that could worsen the dissection. CV-BC nurses must rapidly synthesize history and physical findings to identify this life-threatening condition and activate the appropriate institutional pathway.

Comprehensive and Detailed Explanation:

Invasive procedures, legal and ethical considerations, and risk-reduction measures are part of Planning and Implementation. Device implantation requires documented informed consent, careful management of antithrombotic therapy to balance bleeding and thromboembolic risk, and peri-procedural antibiotics to reduce infection risk. Nurses coordinate these safety elements, provide pre-procedure education, and ensure the patient understands post-implant restrictions and follow-up. Thorough preparation supports successful device therapy outcomes.

Comprehensive and Detailed Explanation:

Prioritization and interventions for acute heart-failure decompensation fall under Planning and Implementation. Nitroglycerin and diuretics reduce preload and afterload but can cause hypotension; simultaneous respiratory support is often required. Continuous monitoring allows rapid titration and early detection of deterioration. Nurses also position the patient upright, prepare for possible non-invasive or invasive ventilation, and coordinate ongoing therapy. This integrated approach reflects evidence-based management of cardiogenic pulmonary edema.

Comprehensive and Detailed Explanation:

Recognition and treatment of adverse reactions (HIT is specifically listed) is a core Evaluation and Modification skill. A significant platelet drop plus thrombosis constitutes high clinical probability of HIT. Immediate cessation of all heparin (including flushes and coated catheters), laboratory confirmation, and transition to an alternative anticoagulant (argatroban, bivalirudin, or fondaparinux) are mandatory. Platelet transfusion is generally avoided. Prompt nursing recognition and action prevent further life- or limb-threatening thrombosis.

Comprehensive and Detailed Explanation:

Pharmacologic therapies and safety considerations are critical under Planning and Implementation. Prasugrel is contraindicated in patients with prior stroke or TIA and is generally avoided in those ≥75 years or weighing <60 kg because of increased bleeding risk. Nurses screen for these contraindications, confirm the indication (usually ACS managed with PCI), and educate the patient about bleeding precautions and the importance of adherence. Safe selection and administration reduce preventable hemorrhagic complications.
