WGU C478 - Critical Care Nursing Clinical Learning. Exam Review Questions ad answers, Rated A+ What is the typical setting for Tidal Volume? - -10-12 mL/kg What is the typical setting for pressure support? - -5-10 cm H2 Which of the following ventilator alarms can be caused by a kinked/clogged tubing? - -High Pressure Limit Which of the following ventilator alarms can happen when the patient stops spontaneously breathing on their own? - -low exhaled tidle volume Which of the following ventilator alarms can happen when a patient disconnects their ET tube from the ventilator tubing? - -low inspiratory pressure The nurse is discussing the pharmacological treatment of a pulmonary embolism (PE) - - Streptokinase is a fibrinolytic reserved for severe PE. Heparin is administered to prevent further clots from forming and has no effect on the existing clot. The heparin should be adjusted to maintain the activated partial thromboplastin time (aPTT) in the range of 2 to 3 times of upper normal. Warfarin should be started at the same time, and when the international normalized ratio (INR) reaches 3.0, the heparin should be discontinued. The INR should be maintained between 2.0 and 3.0. The patient with an arterial line has a systolic blood pressure of 110 on inspiration but 128 on expiration. This is known as - -The patient is experiencing pulsus paradoxus, which is a drop in systolic blood pressure owing to increased intrathoracic pressure during inspiration. This is often the result of volume depletion or cardiac tamponade. Pulsus alternans is a pattern of amplitude change noted in end-stage left ventricular failure. Narrowed pulse pressure is a compensatory mechanism noted with vasoconstriction, and vascular bruit is a sound noted when there is vascular turbulence, especially with increased plaque buildup. The patient has a diastolic murmur located at the fifth intercostal space (ICS) midclavicular line (MCL). - -Mitral stenosis produces a diastolic murmur that is heard at the fifth ICS/MCL. Tricuspid regurgitation and pulmonic stenosis are systolic murmurs. Aortic regurgitation is a diastolic murmur that is heard at the second ICS right sternal borde The 12-lead EKG reveals ST elevation in leads V1-V4. Where is the MI? - -Anterior MI: ST elevation in leads V1-V4. The 12-lead EKG reveals ST elevation in leads II, III and aVF. Where is the MI? - -Inferior MI: ST elevation in leads II, III and aVF. Treatment for atrial fibrillation/atrial flutter may include which of the following? Select all that apply. - -The main treatments for atrial fib/flutter include 3 meds: anticoagulants, rate controllers and rhythm controllers. If the patient doesn't respond - or if they become more symptomatic, cardioversion is used. *Blood thinners, beta blockers, calcium channel blockers, digoxin, amiodarone, tambicor, cardioversion First-line treatment of ventricular fibrillation is: - -defibrillation Treatment for a conscious, asymptomatic patient with ventricular tachycardia could include which of the following? - -You need rate controllers and rhythm controllers. They are asymptomatic, so no cardioversion is needed yet. *Procainamide, amiodarone, beta blockers, calcium channel blockers AGE RELATED MYOCARDIAL - -Increased myocardial collagen content renders the myocardium less compliant; therefore a decrease in myocardial compliance can adversely affect diastolic filling (through decreased distensibility and dilation) and myocardial relaxation. Consequently, the left ventricle must develop a higher filling pressure for a given increase in ventricular volume. CMV - -Which of the following ventilator modes delivers oxygen at a preset tidal volume or pressure in response to the patient's inspiratory efforts and initiates a breath if the patient fails to do so within the preset time
