Correct Answer: D

Rationale: In a high-stress situation like a multiple-car accident with multiple trauma clients arriving at the Emergency Department, autocratic leadership is most effective. This type of leadership allows for clear direction and quick decision-making, crucial in managing emergencies. Democratic leadership may slow down the decision-making process due to the need for consensus. Bureaucratic leadership focuses on following established rules and procedures, which may not be flexible enough in an emergency. Laissez-faire leadership, characterized by a hands-off approach, is not suitable in urgent situations where immediate action is required.

Correct Answer: A

Rationale: The most important goal for a 55-year-old female patient with type 2 diabetes and imbalanced nutrition due to more than body requirements is to reach a glycosylated hemoglobin level of less than 7%. This goal directly addresses the management of diabetes and is crucial in preventing complications associated with high blood sugar levels. Choice B focuses on weight loss, which may be beneficial but is not as critical as controlling blood sugar levels. Choice C, distributing calories throughout the day, is important for glycemic control but not as immediate as reaching a target HbA1c level. Choice D, stating the reasons for eliminating simple sugars, is a good educational goal but not as urgent as achieving glycemic control.

Correct Answer: A

Rationale: The correct action for the nurse to take when caring for a client with tuberculosis is to use antimicrobial sanitizer for hand hygiene. Tuberculosis is primarily spread through the air, so wearing a surgical mask when providing care (choice B) would be more appropriate for diseases transmitted via droplets. Limiting visitors (choice C) and wearing gloves for oral care (choice D) are important infection control measures but are not specifically tailored to tuberculosis transmission.

Correct Answer: A

Rationale: The concept of resilience in healthcare refers to the ability to bounce back and recover quickly from setbacks, such as adverse events, stress, or failures. This resilience allows healthcare professionals to navigate challenges effectively and continue providing quality care to patients. Choice B, strict adherence to protocols, though important, does not fully encompass the flexibility and adaptability required for resilience. Choice C, adapting to changing environments, is closely related to resilience but does not solely define it. Choice D, maintaining consistent performance, is valuable but does not capture the aspect of overcoming setbacks and bouncing back resiliently.

Correct Answer: A

Rationale: Before a person becomes violent, observable behaviors may include tense shoulders, clenched fists, a blank stare, and being positioned with one foot in back and an arm pulled back. Wandering is not typically associated with threatening behaviors signaling imminent violence. DelBel (2003) suggests that strategies such as relaxed body language, maintaining physical distance, and silence can help de-escalate an agitated individual's response.
