The nurse practitioner works in an overnight sleep laboratory, assessing and diagnosing clients with sleep apnea. During this diagnostic procedure, the nurse notes that one client’s blood pressure is 162/97 mm Hg. The nurse explains this connection to the client based on which pathophysiologic principle? When airways are obstructed, the body will retain extracellular fluid so that this fluid can be shifted to intravascular space to increase volume. Specialized cells are located in the back of the throat that signal when the airway is obstructed; this sends signals to the kidney to increase the pulse rate. When the client starts to snore, the epiglottis is closed over the trachea. During apneic periods the client experiences hypoxemia, which stimulates chemoreceptors to induce vasoconstriction.
