Nursing informatics, what does USB mean

Correct Answer: B

Rationale: The correct answer is B: Universal Serial Bus. USB is a common interface used to connect devices to a computer. Nursing informatics often involves using various devices that connect via USB. Choice A, Updated System Binary, is incorrect as it does not accurately describe USB. Choices C and D are blank options, making them obviously incorrect. In summary, USB stands for Universal Serial Bus, a widely used interface in nursing informatics for connecting devices to computers.

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 because biologic sex is determined by both external and internal genitalia, which are physical characteristics present at birth. This is based on chromosomal and hormonal factors that dictate the development of male or female reproductive organs. Choice A is incorrect as sexual intercourse does not determine biologic sex. Choice C refers to gender identity, not biologic sex. Choice D pertains to sexual orientation, not biologic sex. In summary, the physical characteristics of external and internal genitalia are the key factors in determining a person's biologic sex.

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: C

Rationale: The correct answer is C: Review the events leading up to each medication administration error. This strategy is the most critical initial step in addressing medication administration errors. By conducting a thorough review of the events leading up to each error, the committee can identify root causes and contributing factors, allowing for targeted interventions to prevent similar errors in the future. This approach aligns with the principles of continuous quality improvement (CQI) by focusing on understanding the underlying issues before implementing solutions. Choice A: Providing an inservice on medication administration to all nurses may be beneficial, but without understanding the specific factors contributing to errors, the impact may be limited. Choice B: Requiring staff nurses to pass a medication administration examination focuses on individual competency, which is important but not as effective as addressing system issues that contribute to errors. Choice D: Developing a quality improvement program for nurses involved in errors is necessary but should come after identifying and addressing the root causes of errors through a comprehensive review process.

Correct Answer: B

Rationale: The correct answer is B: 12 feet. This distance is established to prevent fires as oxygen supports combustion. Smoking within 12 feet of oxygen administration poses a significant fire hazard. Choice A (4 meters) is incorrect as it is greater than 12 feet. Choices C and D are incorrect as they do not provide a specific distance requirement.

Correct Answer: B

Rationale: The correct answer is B: Depression. The patient's symptoms such as being easily distracted, recent life changes, and the loss of his pet suggest a mood disorder rather than a cognitive impairment like dementia (A) or delirium (C). The patient's alertness and ability to engage in conversation indicate that he is not experiencing delirium. Additionally, the patient's medical history of diabetes makes a hypoglycemic reaction (D) less likely, as he is alert during the assessment. Depression is a common comorbidity in patients with chronic illnesses like osteoarthritis and diabetes, and the recent life stressors could exacerbate his depressive symptoms.

Correct Answer: C

Rationale: Rationale: 1. Occult blood in stool can indicate gastrointestinal bleeding, a serious complication of prolonged ibuprofen use. 2. Gastrointestinal bleeding can lead to anemia, hypovolemia, and shock. 3. Promptly addressing bleeding is crucial to prevent further complications. 4. Diarrhea, Hematuria, and Ova & Parasites are less likely related to ibuprofen use for back pain and are not immediate priorities.

Correct Answer: A

Rationale: The correct answer is A: The slower the pulse. As people age, their heart muscles may weaken, causing the heart to pump less efficiently, resulting in a slower pulse rate. This physiological change is a common part of the aging process. Choice B is incorrect as aging typically leads to a decrease, not an increase, in pulse rate. Choices C and D are left blank as they are irrelevant to the question.
