A nurse is serving on a continuous quality improvement (CQI) committee that has been assigned to develop a program to reduce the number of medication administration errors following a sentinel event at the facility. Which of the following strategies should the committee plan to initiate first?

Correct Answer: C

Rationale: Step 1: Reviewing the events leading up to each medication administration error is the most crucial first step. It allows the committee to understand the root causes of the errors, identify patterns or common factors contributing to errors, and develop targeted interventions to prevent future errors. Step 2: Providing an inservice on medication administration to all nurses (Choice A) is important but should come after understanding the specific issues causing errors. Step 3: Requiring staff nurses to demonstrate competency by passing an examination (Choice B) is not the most effective initial strategy as it focuses on individual performance rather than systemic issues. Step 4: Developing a quality improvement program for nurses involved in errors (Choice D) is important but should follow the analysis of the errors to ensure the program's effectiveness in addressing the identified issues.

Correct Answer: B

Rationale: The correct answer is B: Hypothermia. Subnormal core body temperature indicates the body temperature is below normal range, which is characteristic of hypothermia. Hyperthermia refers to elevated body temperature, making choice A incorrect. Choices C and D are likely not provided as they do not directly relate to the concept of body temperature.

Correct Answer: B

Rationale: The correct answer is B: Clear and light sample. This is because sputum should ideally be clear and light in color, indicating a lower presence of mucus and other contaminants. A cloudy, thick sample (choice A) may indicate an infection or presence of pus. Choices C and D are likely left blank as they are irrelevant or incorrect responses. In summary, a clear and light sputum sample is preferred for accurate testing and diagnosis.

Correct Answer: B

Rationale: The correct answer is B: Intact skin. Intact skin acts as the first defense against infection by forming a physical barrier that prevents pathogens from entering the body. It is composed of multiple layers, including the epidermis and dermis, which provide protection against microbes. Skin also produces antimicrobial substances and has immune cells that can defend against pathogens. A: Skin is not specific enough, as damaged skin may not provide effective protection. C and D are incomplete answers and do not accurately describe the primary role of intact skin in defending against infections.

Correct Answer: B

Rationale: The correct answer is B because a vesicle is a small fluid-filled blister on the skin. Vesicles are commonly caused by friction, burns, or insect bites, resulting in fluid accumulation beneath the skin. Pus is typically associated with larger, infected lesions such as pustules, not vesicles. Choice C and D are likely incorrect as they do not provide relevant information or support for the appearance of a vesicle on the leg.
