Because of the failure to replace the defective electric fan immediately, a fire broke out and it became big enough to burn a major portion of the unit because the fire extinguisher was missing. What lesson can be gained from this?

Correct Answer: D

Rationale: The lesson that can be gained from this scenario is that every protocol must be followed. In this situation, failure to replace the defective electric fan immediately and having a missing fire extinguisher directly led to the fire escalating and causing significant damage. By ensuring that all safety protocols and procedures are followed promptly and consistently, potential hazards and risks can be mitigated or prevented. It is crucial for employees to understand the importance of adhering to established protocols in order to maintain a safe working environment and prevent accidents or emergencies.

Rationale: In a stratified sampling method, the population is divided into subgroups or strata based on certain characteristics that are relevant to the research objective. This allows for representation from each subgroup in the sample, ensuring that different segments of the population are taken into account.

Correct Answer: B

Rationale: The independent variable in an experiment is the variable that is manipulated or determined by the researcher. In this hypothesis, the nurse is suggesting that the age of the patient (elderly vs. younger) influences the aggressiveness of treatment received. Therefore, the age of the patient is the independent variable in this scenario. The dependent variable would be the degree of treatment received, as it is expected to be influenced by the independent variable, which is the age of the patient.

Correct Answer: C

Rationale: To create personal time as a nurse with rotating shifts, it is important to prioritize personal well-being and make time for oneself. By eliminating tasks that add no value, nurses can streamline their workload and focus on essential responsibilities. This can help in reducing unnecessary stress and allowing for more personal time outside of work. Delegating work to others and filling every moment with tasks or chores may not necessarily create personal time, as it can keep nurses constantly busy and overwhelmed. Hiring someone else to do the work may not always be feasible or practical in a nursing setting, but by eliminating non-essential tasks, nurses can better manage their time and have more opportunities for personal activities and self-care.

Correct Answer: C

Rationale: Nurse Gay should use abbreviations that are part of an approved standard list by the hospital. Using standardized abbreviations ensures clarity, accuracy, and consistency in documentation.
