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
, 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
