Med Surg Exam 3C QUESTIONS WITH 100% VERIFIED ANSWERS Shock is a life-threatening condition that results from inadequate tissue perfusion. Rapid assessment with early recognition and response to shock states is essential to the patient's recovery.=======true Normal pulse pressure, which is 60 to 80 mm Hg, is calculated by dividing the diastolic measurement from the systolic measurement.=======false Failure of the cardiac pump occurs in the progressive stage of shock.=======true The most common and serious side effects of fluid replacement are cardiovascular overload and pulmonary edema.=======true Cardiogenic shock, the most common type of shock, occurs when there is a reduction in intravascular volume by 15% to 30%.=======false Regardless of the initial cause of shock, certain physiologic responses common to all types include hypoperfusion of tissues,______________ and activation of the inflammatory response.=======hypermetabolism Failure of ____________ mechanisms to effectively restore physiologic balance is the final pathway of all shock states and results in end-organ dysfunction and death.=======compensatory If fluid therapy alone does not effectively improve tissue perfusion, vasopressor agents, specifically ____________ or dopamine, may be initiated to achieve a MAP of 65 mm Hg or higher.=======norepinephrine A modified ____________ position is recommended for patients in hypovolemic shock to assist with fluid redistribution.=======trendelenburg Elevated body temperature (hyperthermia), common with sepsis, is considered to be at a dangerous level when it reaches _______=======104 The medulla contains the nephrons, the structural and functional units of the kidney responsible for urine formation.=======false The angling of the ureterovesical junction is the primary factor preventing backward movement of urine from the bladder toward the kidney.=======true Urea is an abnormal constituent of urine.=======false The glomerular filtration rate decreases at a yearly decline of about 1 mL/min after age 40.=======true When fluid intake decreases, specific gravity increases.=======true Enclosed in an epithelial structure called Bowman capsule, the _________ is a unique network of capillaries that form that part of the nephron through which filtration occurs.=======glomerulus Regulation of sodium volume excretion depends on _________, a hormone synthesized and released from the adrenal cortex.=======aldosterone Dull, continuous pain that is located over the suprapubic area is most likely pain involving the ________=======bladder The normal adult bladder capacity is ________ of urine.=======400 to 500 mL Bladder _____________ is a noninvasive method of measuring urine volume in the bladder that can be performed by the nurse at the bedside.=======ultrasonography Diabetes is the primary cause of chronic kidney disease.=======true
