The concentration of potassium ions (K + ) is high in the intracellular fluid (ICF). It determines volume and intracellular osmolarity of the cell. It regulates resting membrane potential and depolarization of nervous and muscular systems with sodium. It serves as a co-factor for translation and is involved in other metabolic processes. Homeostasis of K + is linked with sodium. Nearly 90% of K + ions are filtered through the glomerulus, and are reabsorbed by the proximal convoluted tubule (PCT). The rest of the K + ions are excreted through the urine. Later, nephron controls the variations in the K + ion excretion; distal convoluted tubules and collecting duct (CD) return the amount of K + ions to the tubular fluid. When K + concentration is more, high amount of K ions is released by tubules. If the K + concentration is low, low amount of K + ions is secreted by the tubules.

Summary Introduction

Introduction:

The concentration of potassium ions (K⁺) is high in the intracellular fluid (ICF). It determines volume and intracellular osmolarity of the cell. It regulates resting membrane potential and depolarization of nervous and muscular systems with sodium. It serves as a co-factor for translation and is involved in other metabolic processes. Homeostasis of K⁺ is linked with sodium. Nearly 90% of K⁺ ions are filtered through the glomerulus, and are reabsorbed by the proximal convoluted tubule (PCT). The rest of the K⁺ ions are excreted through the urine. Later, nephron controls the variations in the K⁺ion excretion; distal convoluted tubules and collecting duct (CD) return the amount of K⁺ ions to the tubular fluid. When K⁺ concentration is more, high amount of K ions is released by tubules. If the K⁺ concentration is low, low amount of K⁺ ions is secreted by the tubules.

rewrite: Problem 1 (Mental Health): The survivor victim is dealing with acute stress and symptoms of a post-traumatic stress disorder (PTSD) due to their traumatic experience during the January 2025 wildfire. Goal 1: To alleviate the client's overall level, frequency, and intensity of anxiety and PTSD symptoms so that daily functioning remains unimpaired. Objective 1: The client will learn and regularly use at least two anxieties management techniques to reduce anxiety symptoms to less than three episodes per week. Intervention 1: The therapist will provide psychoeducation about anxiety and PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.
