The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
Questions on the NCLEX exam are of three different types or levels: Level 1, Level 2, and Level 3. Level 1 questions are the most basic questions and make up less than 10 percent of the total questions. Level 1 questions test the individual's knowledge and understanding. These questions require the individual to recall specific facts and ...
The Emergency Severity Index (ESI) is a five-level emergency department triage algorithm, initially developed in 1998 by emergency physicians Richard Wurez and David Eitel. [1] It was previously maintained by the Agency for Healthcare Research and Quality (AHRQ) but is currently maintained by the Emergency Nurses Association (ENA). Five-level ...
An ABI range of 0.90 to 1.40 is considered normal. A person is considered to have PAD when the ABI is ≤ 0.90. However, PAD can be further graded as mild to moderate if the ABI is between 0.41 and 0.90, and severe if the ABI is less than 0.40. These categories can provide insight into the disease course. [42]
Unlicensed assistive personnel are important members of the health care team who often hold a high level of experience and ability. While they do not require extensive health care training to practice their profession, manual dexterity and good interpersonal communication skills are usually necessary.
Activities of daily living (ADLs) is a term used in healthcare to refer to an individual's daily self-care activities. Health professionals often use a person's ability or inability to perform ADLs as a measure of their functional status.
One application of multilevel modeling (MLM) is the analysis of repeated measures data. Multilevel modeling for repeated measures data is most often discussed in the context of modeling change over time (i.e. growth curve modeling for longitudinal designs); however, it may also be used for repeated measures data in which time is not a factor.
This yields a single-level mathematical program with complementarity constraints, i.e., MPECs. If the lower level problem is not convex, with this approach the feasible set of the bilevel optimization problem is enlarged by local optimal solutions and stationary points of the lower level, which means that the single-level problem obtained is a ...
