EMT FISDAP Cardiology Exam | 78 Quotation And Answers Which intervention or interventions would have the MOST positive impact on the cardiac arrest patient's outcome? Correct Ans ➡ Early CPR and defibrillation The AED gives "no shock" message to a patient who is in cardiac arrest. You should: Correct Ans ➡ Resume chest compressions What is the maximum amount of time that should be spent checking for spontaneous breathing in an unresponsive child? Correct Ans ➡ 10 seconds When performing CPR on an adult, you should compress the chest to a depth of ___ at a rate of ___. Correct Ans ➡ 2.0-2.4 in, 100-150BPM What is the appropriate compression to ventilation ratio for adult two-rescuer CPR?
Correct Ans ➡ 30:2
When checking for a pulse in an infant, which artery should you palpate? Correct Ans ➡ Brachial When performing CPR on an adult or child, you should reassess the patient for return of respirations/circulation every ____ minutes. Correct Ans ➡ 2 What is the preferred method of removing a foreign body in an unresponsive child?Correct Ans ➡ Chest compressions Cardiogenic shock is caused by: Correct Ans ➡ Inadequate function of the heart muscle Pericardial effusion Correct Ans ➡ Collection of fluid between the pericardial sac and the myocardium Cardiac tamponade Correct Ans ➡ Occurs when blood leaks into the space between the pericardium and the pericardial sac Signs and symptoms of cardiac tamponade: Correct Ans ➡ Beck triad: the presence of jugular vein distention, muffled heart sounds, and a narrowing pulse pressure where the systolic and diastolic blood pressures start to merge.Signs of cardiogenic shock: Correct Ans ➡ -Skin may be cool, clammy, and ashen -High BP -Rapid, shallow breathing -Weak, irregular pulse -Anxiety, nausea 1 / 2
You arrive on scene to find a conscious 58YOF sitting up and reporting severe chest pain and SOB. She is anxious and "feels like she's going to die." Her skin is pale, cool, and clammy and her pulse is rapid, weak, and irregular. Her breathing is labored, with a RR of 28 breaths/min. Her SpO2 is 90%. Lung sounds show crackles in all fields, and BP is 92/60 mmHg. What is your differential diagnosis of the patient? Correct Ans ➡ Cardiogenic shock The heart is divided down the middle into left and right sides by the: Correct Ans ➡ Septum Which chamber of the heart receives incoming unoxygenated blood? Correct Ans ➡ Atrium Which chamber of the heart pumps oxygenated blood? Correct Ans ➡ Ventricles Normal electrical impulses begin in the: Correct Ans ➡ Sinoatrial (SA) node What characteristic allows a cardiac muscle cells to contract spontaneously without an external stimulus? Correct Ans ➡ Automaticity The sympathetic nervous system acts on the body by: Correct Ans ➡ -increasing HR and RR -constricting blood vessels in the muscles
The parasympathetic nervous system acts on the body by: Correct Ans ➡
(directly opposes the sympathetic NS) -decreases HR and RR -constricts blood vessels in muscles Increased oxygen demand in a normal heart is supplied by ______ of the coronary arteries. Correct Ans ➡ Dilation The heart itself is supplied by blood through what vessels? Correct Ans ➡ Coronary vessels
The iliac arteries descend into the: Correct Ans ➡ femoral arteries
Which veins bring blood back to the right atrium? Correct Ans ➡ Venae cavae Systolic pressure is the: Correct Ans ➡ maximum pressure generated in the arteries during contraction of the left ventricle Pulses felt in the extremities are called: Correct Ans ➡ Peripheral pulses Pulses felt near the trunk of the body are called: Correct Ans ➡ Central pulses
