Explanation
When taking an electronic blood pressure measurement, it is important to properly position the cuff on the client’s arm. The artery indicator on the blood pressure cuff should be aligned with the client’s brachial artery1. It is also important to select a cuff that fits properly and to have the client sit comfortably with their back supported and feet flat on the ground2.
Correct Answer is D
Explanation
The first step in the inflammatory response is the recognition of harmful stimuli by pattern recognition receptors (PRRs) on the surfaces of various cells, including immune cells and non-immune cells. PRRs recognize specific patterns associated with pathogens, damage-associated molecular patterns (DAMPs), and pathogen-associated molecular patterns (PAMPs), among others. This recognition leads to the activation of signaling pathways that promote the recruitment and activation of immune cells and the release of inflammatory mediators, such as cytokines and chemokines.
Once the PRRs recognize the harmful stimuli, inflammatory cells are activated, including neutrophils, macrophages, and dendritic cells. These cells then release inflammatory markers, such as C-reactive protein, which promote the recruitment and activation of more immune cells and further amplify the inflammatory response. Inflammatory pathways are also triggered, leading to the production of various inflammatory mediators and the activation of transcription factors that regulate the expression of genes involved in the inflammatory response.
