CPR Practice Test: Video 6 Answers (25 Questions) — Questions and Answers

Question 1: What is the first step after recognizing an adult is unresponsive and not breathing normally?

Activate the emergency response system and get an AED (Correct answer)
Give two rescue breaths
Check pulse for 2 minutes
Begin chest compressions

Correct answer: Activate the emergency response system and get an AED

After confirming unresponsiveness, immediately activate EMS and retrieve an AED before starting CPR.

Question 2: What is the recommended epinephrine dose for adult cardiac arrest in the BLS/ACLS context?

0.5 mg IV every 5 minutes
1 mg IV every 3-5 minutes (Correct answer)
0.1 mg IV every minute
2 mg IV once

Correct answer: 1 mg IV every 3-5 minutes

The standard epinephrine dose for adult cardiac arrest is 1 mg IV/IO every 3-5 minutes.

Question 3: For an infant, which artery is used to check the pulse?

Temporal
Radial
Brachial (Correct answer)
Carotid

Correct answer: Brachial

The brachial artery on the inside of the upper arm is used for infant pulse checks.

Question 4: When an AED advises 'no shock advised' but the patient remains in arrest, what should you do?

Reanalyze right away
Remove the pads
Immediately resume chest compressions (Correct answer)
Wait for EMS

Correct answer: Immediately resume chest compressions

If no shock is advised, immediately resume high-quality CPR starting with compressions.

Question 5: For an adult in cardiac arrest, what is the recommended chest compression depth?

Exactly 1.5 inches (4 cm)
About 3.5 inches (9 cm)
At least 1 inch (2.5 cm)
At least 2 inches (5 cm) but no more than 2.4 inches (6 cm) (Correct answer)

Correct answer: At least 2 inches (5 cm) but no more than 2.4 inches (6 cm)

Adult compressions should be at least 2 inches but not exceeding 2.4 inches to maximize perfusion without injury.

Question 6: What is the primary goal of post-resuscitation care?

Prevent recurrence and improve outcomes (Correct answer)
Administer sedatives
Initiate CPR again
Prepare for discharge

Correct answer: Prevent recurrence and improve outcomes

Post-resuscitation care focuses on stabilizing the patient after return of spontaneous circulation (ROSC) and addressing the underlying cause of the cardiac arrest. The primary goal is to prevent further cardiac events, manage organ dysfunction resulting from the arrest, and optimize neurological recovery to improve the patient's overall long-term outcome and quality of life.

Question 7: After return of spontaneous circulation (ROSC), what oxygen saturation range should be targeted to avoid hyperoxia?

94-99% (Correct answer)
100% at all times
85-90%
70-80%

Correct answer: 94-99%

Titrate oxygen to keep SpO2 between 94-99% to prevent both hypoxia and harmful hyperoxia.

Question 8: Which laboratory abnormality is commonly monitored and corrected during post-resuscitation care?

Blood glucose (Correct answer)
Hair color
Bone density
Eye pressure

Correct answer: Blood glucose

Both high and low blood glucose worsen outcomes, so glucose is monitored and kept in a moderate range.

Question 9: Targeted temperature management after cardiac arrest typically maintains core temperature in which range?

28-30 C
25-27 C
38-40 C
32-36 C (Correct answer)

Correct answer: 32-36 C

Current guidelines recommend a constant target between 32 C and 36 C for at least 24 hours.

Question 10: Which finding immediately after ROSC most strongly indicates the need to identify and treat a reversible cause?

Spontaneous eye opening
Persistent hypotension (Correct answer)
Strong radial pulse
Normal blood pressure

Correct answer: Persistent hypotension

Persistent hypotension signals ongoing instability and prompts a search for reversible causes like hypovolemia.

Question 11: How many rescuers are needed for the 15:2 compression-to-ventilation ratio in children?

Any number
2 (Correct answer)
1
3

Correct answer: 2

Two rescuers are needed for the 15:2 compression-to-ventilation ratio in children. This ratio is used in two-rescuer CPR for children to provide more frequent ventilations, which are often more critical for pediatric cardiac arrest. The presence of two rescuers allows for more efficient delivery of both compressions and breaths.

Question 12: What is the correct compression depth for an adult during CPR?

At least 2 inches (5 cm) (Correct answer)
About 1 inch (2.5 cm)
Exactly 4 inches (10 cm)
At least 3 inches (7.5 cm)

Correct answer: At least 2 inches (5 cm)

Adult compressions should be at least 2 inches but no more than 2.4 inches deep.

Question 13: Why is full chest recoil important between compressions?

It lets the heart refill with blood (Correct answer)
It conserves the rescuer's energy
It prevents rib fractures entirely
It increases body temperature

Correct answer: It lets the heart refill with blood

Allowing complete recoil lets the heart refill so the next compression circulates more blood.

Question 14: What compression-to-ventilation ratio is used for a single rescuer performing CPR on an adult?

30:2 (Correct answer)
15:2
5:1
10:2

Correct answer: 30:2

A single rescuer uses 30 compressions to 2 breaths for adults.

Question 15: Which is an appropriate hand placement for CPR on a child?

Over the ribs
Upper sternum
Lower half of the sternum (Correct answer)
Left side of chest

Correct answer: Lower half of the sternum

An appropriate hand placement for CPR on a child is on the lower half of the sternum. Similar to adults, this central chest placement ensures that compressions are delivered directly over the heart. Using one or two hands, depending on the child's size, helps achieve the correct depth and effectiveness while avoiding injury.

Question 16: When using an AED, what must you do before delivering a shock?

Give a rescue breath
Remove the pads
Ensure no one is touching the victim (Correct answer)
Pour water on the chest

Correct answer: Ensure no one is touching the victim

Everyone must be clear of the victim so the shock is not absorbed by a rescuer.

Question 17: After performing CPR on a victim, how many minutes do you wait to check their pulse again?

1
50 seconds
3 (Correct answer)
2

Correct answer: 3

The absence of a pulse, along with unresponsiveness and no normal breathing, is the primary indicator for initiating chest compressions in CPR. Chest compressions are vital to circulate blood and oxygen to the brain and other vital organs when the heart is not effectively pumping on its own. Therefore, if a victim has no pulse, CPR should be performed.

Question 18: Which of these is a sign of an arterial bleed?

Clear fluid leaking
No visible blood at all
Bright red blood spurting with each heartbeat (Correct answer)
Slow, steady oozing of dark blood

Correct answer: Bright red blood spurting with each heartbeat

Arterial bleeding produces bright red blood that spurts in rhythm with the heartbeat.

Question 19: What type of shock results specifically from severe blood or fluid loss?

Cardiogenic shock
Hypovolemic shock (Correct answer)
Septic shock
Anaphylactic shock

Correct answer: Hypovolemic shock

Hypovolemic shock is caused by a significant loss of blood or body fluids.

Question 20: For a choking conscious adult, which technique should you use?

Abdominal thrusts (Heimlich maneuver) (Correct answer)
Chest compressions
Have them drink water
Back blows only

Correct answer: Abdominal thrusts (Heimlich maneuver)

Abdominal thrusts are used to dislodge an obstruction in a conscious choking adult.

Question 21: What does 'NIHSS score' of 0 indicate in a stroke patient?

The patient requires immediate surgery
The patient is in a coma
The most severe possible deficit
No neurological deficit detected on examination (Correct answer)

Correct answer: No neurological deficit detected on examination

NIHSS 0 indicates a normal neurological examination with no detectable deficits; scores increase with greater deficit severity up to a maximum of 42.

Question 22: What stroke risk factor is most modifiable and responsible for the highest population-attributable risk?

Genetics
Hypertension (Correct answer)
Age
Gender

Correct answer: Hypertension

Hypertension is the single most important modifiable stroke risk factor, responsible for approximately 35-40% of population-attributable risk.

Question 23: What is the recommended first response action when stroke is suspected in a community setting?

Drive the patient to the hospital immediately
Give the patient aspirin and water
Call 911 immediately and note the time symptoms started (Correct answer)
Wait 30 minutes to see if symptoms resolve

Correct answer: Call 911 immediately and note the time symptoms started

Call 911 immediately and note the exact time symptoms started—this information is critical for determining tPA eligibility at the hospital.

Question 24: What is the maximum time window for administration of tPA (tissue plasminogen activator) for eligible ischemic stroke patients?

1 hour from symptom onset
3-4.5 hours from last known well time (Correct answer)
6 hours from symptom onset
12 hours from symptom onset

Correct answer: 3-4.5 hours from last known well time

tPA can be administered within 3-4.5 hours of last known well time in eligible ischemic stroke patients to dissolve the clot.

Question 25: Which condition is known as a 'stroke mimic' and can be confused with stroke symptoms?

Hypertension
Myocardial infarction
Todd's paralysis (post-ictal weakness after a seizure) (Correct answer)
Atrial fibrillation

Correct answer: Todd's paralysis (post-ictal weakness after a seizure)

Todd's paralysis is focal post-seizure weakness that can perfectly mimic stroke symptoms, making it one of the most common stroke mimics.
