The nurse is caring for a patient in the postanesthesia care unit who has undergone a left total knee arthroplasty. The anesthesia provider has indicated that the patient received a left femoral peripheral nerve block. Which assessment would be an expected finding for a patient with this type of regional block?

Correct Answer: C

Rationale: A left femoral peripheral nerve block, used in knee arthroplasty, targets the femoral nerve, numbing the anterior thigh, knee, and medial leg, so decreased sensation in the left leg is an expected finding. This regional anesthesia blocks sensory pathways, reducing postoperative pain in the targeted area without affecting systemic consciousness. Decreased pulse, cool toes, or cyanosis suggest vascular compromise, not nerve block effects, and would indicate complications like arterial injury. Pain in the left foot contradicts the block's purpose effective anesthesia should prevent this unless it's wearing off or incomplete. The nurse's assessment confirms the block's efficacy, ensuring pain control and monitoring for unintended motor or circulatory issues, per regional anesthesia standards.

Correct Answer: B

Rationale: Securing table attachments with foam padding minimizes skin breakdown by cushioning pressure points (e.g., heels, sacrum) during prolonged intraoperative positioning. Unusual positions for surgical access can cause abrasions or ulcers without protection padding distributes weight, preserving circulation. Bathing pre-surgery reduces microbes, not pressure injury. Adjusting the patient risks sterility breaches and airway disruption, impractical intraoperatively. Measuring time monitors risk but doesn't prevent breakdown. The nurse's use of padding aligns with skin integrity protocols, ensuring safety during immobility under anesthesia.

Correct Answer: B

Rationale: Culture refers to the collective customs, habits, traditions, attitudes, and beliefs that characterize a social group, distinguishing it from others. It's a comprehensive concept that defines a society's way of life. 'Culture,' is correct because it encapsulates all these elements, as defined by Edward Tylor, who described culture as the complex whole of a society's learned behaviors and beliefs. 'Personality,' is incorrect, as it pertains to individual characteristics, not group traits. 'Norm,' refers to specific behavioral rules within a culture, a narrower scope than the broad concept of culture itself. 'Ideology,' denotes a system of ideas, often political or philosophical, which is only a part of culture, not its entirety. Culture's all-encompassing nature, covering the full range of social group attributes listed in the question, makes B the most fitting answer, supported by its foundational role in anthropology and sociology as the shared essence of a community.

Correct Answer: D

Rationale: Viruses are unique pathogens with specific characteristics, and the question seeks the false statement. 'It multiplies by binary fission,' is correct as the exception because viruses do not reproduce via binary fission (a bacterial process of splitting into two); instead, they replicate by hijacking host cells to produce viral components. 'It cannot be grown on inanimate object or artificial media,' is true, as viruses require living host cells, not artificial media alone. 'It possesses either DNA or RNA but never both,' is true, as viruses are either DNA or RNA-based, not dual (per virology texts like Fields Virology). 'It is heat labile,' is true, as most viruses are sensitive to heat. Binary fission's absence in viral replication, contrasted with their reliance on host machinery, makes D the false statement, aligning with established virological principles.

Correct Answer: A

Rationale: System software manages and interacts with hardware, enabling it to function and support other programs. 'System software,' is correct because it includes operating systems (e.g., Windows) and drivers that directly interface with hardware circuits, per software engineering texts (e.g., Sommerville). 'Circuit software,' is not a recognized category. 'Interaction software,' is vague and undefined. 'Application software,' like word processors, relies on system software to access hardware, not interacting directly. System software's role as the bridge between hardware and applications, controlling circuits like CPUs or GPUs, makes A the precise answer, foundational to computer operation.
