Rationale: The initial step in the process of change for the senior nurse should be to identify the inefficiency that needs improvement or correction. Before setting goals, planning strategies, or identifying solutions, it is essential to first pinpoint the specific area or aspect that requires change. By identifying the inefficiency, the senior nurse can gain a clear understanding of the root cause of the issue and focus efforts on addressing it effectively. This step lays the foundation for the rest of the change process by providing a specific target for improvement.

Correct Answer: B

Rationale: A living will is a legal document that allows an individual to express their wishes regarding medical treatment in the event they become unable to make decisions. It specifically outlines the medical treatments a person chooses to refuse or accept under certain circumstances. It is important to differentiate a living will from a durable power of attorney, which designates someone to make healthcare decisions on behalf of the individual when they are unable to do so, and advance directives, which encompass both a living will and a durable power of attorney for healthcare. The living will serves as a guide for healthcare professionals and family members to honor the individual's preferences for medical care.

Correct Answer: D

Rationale: When a patient is crying and continuously pulling at a specific body part, such as Catherine pulling her right ear, it indicates discomfort or pain in that area. Nurse Selma's most appropriate action would be to further assess the description and frequency of the pain. This will help her identify the possible cause of the pain, whether it is due to an ear infection, injury, or any other underlying issue. Understanding the nature and intensity of the pain will guide Nurse Selma in providing appropriate care and intervention for Catherine. It is crucial to address the patient's pain promptly to ensure their comfort and well-being. Referring to the attending physician may be necessary after this initial assessment but assessing the pain should be the immediate priority.

Correct Answer: A

Rationale: Given the sudden-onset severe scrotal pain, swelling, and erythema, along with the physical examination findings of a tender, swollen, and high-riding testicle, the most likely diagnosis is testicular torsion. Testicular torsion occurs when the spermatic cord twists, leading to compromised blood flow to the testicle, causing ischemia and severe pain. It is considered a surgical emergency that requires prompt diagnosis and intervention to salvage the affected testicle. Prompt surgical detorsion is necessary to prevent irreversible testicular damage. While epididymitis, testicular trauma, and testicular tumors can also present with scrotal pain and swelling, the presence of a high-riding testicle in this context is highly suggestive of testicular torsion.

Correct Answer: B

Rationale: In quantitative research, randomness plays a crucial role in eliminating bias. Random sampling ensures that every individual or element in the population has an equal chance of being selected for the study. This helps in reducing the possibility of bias creeping into the results due to selective sampling or favoritism towards certain groups. By using random sampling methods, researchers can increase the generalizability of their findings and have a higher level of confidence that the results are unbiased and representative of the entire population. Therefore, randomness is a key mechanism to eliminate bias in quantitative research studies.
