NCLEX: Assessment of Cardiovascular Function Exam with Complete Solutions The nurse is discussing cardiac hemodynamics with a nursing student. The nurse explains preload to the student and then asks the student what nursing interventions might cause increased preload. The student correctly answers which of the following? Correct response: Application of antiembolytic stockings Explanation: Preload is the amount of blood presented to the ventricles just before systole. Anything that ...

1. A 30-year-old climber is experiencing sever shortness of breath after reaching an elevation of 12000feet. The PT is very anxious and has rales noted to all quadrants but is otherwise healthy.

preload - degree of stretch (volume of blood) of the ventricular muscle fibers at the end of diastole (when filling volume is the greatest). the higher this is the stronger the contraction preload - increased by blood transfusions, IV fluids, hypervolemia, regurgitation preload - decreased by hemorrhage, diuresis, dehydration, vasodilation afterload - resistance to ejection of blood from the ventricles afterload - increased by htn and vasoconstriction afterload - decreased by nitroglyceri...

Introduction to BP. Blood pressure is defined as the force exerted by the blood against the walls of the arteries. Write the equation for blood pressure here: BP = CO x SVR Cardiac output (CO) is defined as the total blood flow through the systemic or pulmonary circulation per minute. Write the equation for CO here: CO = SV x HR  Stroke volume is approximately 70mL/min True or False: A HR of 50bpm would lead to a lower CO than a HR of 80bpm Stroke volume is determined by: 1. Contra...

ST segment elevation - CORRECT ANSWER The classical ECG change with muscle injury in acute myocardial infarction is: CHF - CORRECT ANSWER Elevated cardiac iso-enzymes generally do not occur in which response below? Increased CO - CORRECT ANSWER The major therapeutic goal in the treatment of cariogenic shock is to: Reduce...

Dysrhythmias * they can result in deviations from a normal HR and/or rhythm, causing decreases in cardiac output. Some dysrhythmias are lethal, causing a complete loss of CO, which result in cardiopulmonary arrest. Other dysrhythmias are apparent on ECG's but are symptomless correct answer: Disruptions in the cardiac conduction pathway or disorders of the electrical impulse conduction within the heart HR x SV = CO HR is how many times the heart beats per minute; SV is the amount of...
