●​ Pulse Oximetry : This measures the oxygen saturation of arterial blood and is often performed using a sensor on the client's finger or other appropriate body parts. The normal range for oxygen saturation is 94-100%. ●​ Spirometry : This diagnostic test provides information such as tidal volume, forced vital capacity, maximum inspiratory and expiratory pressure, lung capacity, and other pulmonary function measurements. ●​ Forced Vital Capacity (FVC) : FVC measures the volume of air a client can expel against resistance and reflects the strength of respiratory muscles. ●​ Forced Expiratory Volume (FEV1) : This measurement assesses the lung's ability to forcefully exhale for one second. ●​ Diffusion Capacity (DLCO) : DLCO measures the lung's ability to transfer oxygen from inhaled air to the bloodstream. The normal level is around 25 mL/min/mm Hg. ●​ I:E Ratio : The ratio of the duration of inspiration to expiration. A normal ratio is 1:2, but it can become altered in respiratory disorders like asthma, chronic bronchitis, and emphysema. ●​ Minute Volume : Minute volume is the amount of air inhaled or exhaled in one minute. ●​ Expiratory Reserve Volume : This is the maximum volume of air that can be exhaled after a normal exhalation. ●​ Inspiratory Reserve Volume : It is the maximum volume of air that can be inhaled after a normal inhalation. ●​ Residual Volume : Residual volume is the air remaining in the lungs after a forceful exhalation. ●​ Exercise Testing : Different types of exercise testing, such as exercise-induced bronchoconstriction tests, full cardiopulmonary exercise testing, and the Six-Minute Walk test, can assess a client's respiratory and cardiovascular responses during exercise. The nurse integrates the client's signs and symptoms with these diagnostic results and collaborates with the healthcare team, including physicians, nurse practitioners, physician assistants, and certified respiratory therapists, to provide comprehensive care and follow-up for the client's respiratory issues.

Maintaining Optimal Client Temperature Normal body temperature exhibits minimal individual variation, with minor fluctuations due to the body's circadian rhythm. However, deviations from this narrow range can lead to specific conditions:
