A patients severe asthma has necessitated the use of a long-acting beta2-agonist (LABA). Which of the patients statements suggests a need for further education?

Correct Answer: C

Rationale: A patient's statement about using a long-acting beta2-agonist (LABA, e.g., salmeterol) ‘each time I feel an asthma attack coming on' signals a need for further education, as LABAs are for maintenance, not rescue. LABAs prevent bronchospasm over 12-24 hours, not acutely relieving symptoms that's the role of short-acting beta-agonists (e.g., albuterol). Misuse risks delaying effective treatment, worsening attacks. Tachycardia is a known side effect, correctly noted. LABAs do prevent exercise-induced asthma, a valid benefit. Tolerance (less effectiveness over time) can occur, a fair concern. The nurse must clarify LABA's prophylactic role twice-daily dosing versus rescue inhalers, ensuring the patient's action plan prevents severe exacerbations, per asthma management standards.

Correct Answer: B

Rationale: The nurse delegates to the nursing assistant to inform if patients are unwilling to perform exercises, leveraging their scope to observe and report while retaining oversight for follow-up. Teaching and demonstrating exercises require nursing judgment, beyond the assistant's role. Documentation in the medical record is a nursing responsibility for legal accuracy. Doing nothing neglects patient care needs. This delegation ensures the nurse addresses barriers like pain or reluctance, maintaining exercise compliance to prevent complications like thrombosis or atelectasis, per collaborative care principles.

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.
