Postural hypotension is likely in the setting of decrease in preload whih decrease? ANSWER: cardiac output; sustained decrease of at least 20 mm Hg in systolic BP or 10 mm Hg in diastolic BP within 3 minutes of moving from a lying or sitting to a standing position. It is usually accompanied by dizziness, lightheadedness, or syncope. | Assessing Patients for Postural Hypotension The following steps are recommended when assessing patients for postural hypotension: 1. Position the patient supine for 10 minutes before taking the initial blood pressure (BP) and heart rate measurements. 2. Reposition the patient to a sitting position with legs in the dependent position, wait 2 minutes, then reassess both BP and heart rate measurements. 3. If the patient is symptom free or has no significant decreases in systolic or diastolic BP, assist the patient into a standing position, obtain measurements immediately, and recheck in 2 minutes; continue measurements every 2 min for a total of 10 minutes to rule out postural hypotension. 4. Return the patient to a supine position if postural hypotension is detected or if the patient becomes symptomatic. 5 Document heart rate and BP measured in each position (e.g., supine, sitting, and standing) and any signs or symptoms that accompany the postural changes. The blood pressure represents the amount of pressure that's exerted on the walls of the arteries during systole and diastole and is influenced by? ANSWER: cardiac output and peripheral vascular resistance (distention of the arteries) Auscultate the apical pulse (point of maximal impulse) at the: ANSWER: intersection of the FIFTH intercostal space and MIDCLAVICULAR lin
