CPR Practice Test: Video 4 Answers (24 Questions) — Questions and Answers

Question 1: In what situation should a healthcare provider use the jaw-thrust maneuver instead of head-tilt chin-lift?

When the patient has dentures
When cervical spine injury is suspected (Correct answer)
When the patient is a child
When bag-valve-mask ventilation is being used

Correct answer: When cervical spine injury is suspected

The jaw-thrust maneuver is used when cervical spine injury is suspected to avoid neck extension that could worsen a spinal injury.

Question 2: Before delivering an AED shock, what must the rescuer ensure?

Oxygen is flowing over the chest
No one is touching the patient ('clear') (Correct answer)
Compressions continue during the shock
Everyone is touching the patient

Correct answer: No one is touching the patient ('clear')

Ensure no one is in contact with the patient and call 'clear' before delivering a shock.

Question 3: A healthcare provider finds an unresponsive adult. After confirming no normal breathing and no pulse, what is the FIRST action?

Activate the emergency response system (call for help/AED)
Begin chest compressions (Correct answer)
Apply the AED immediately
Give 2 rescue breaths

Correct answer: Begin chest compressions

For a witnessed cardiac arrest with another rescuer present, begin chest compressions immediately while a second rescuer activates EMS and retrieves an AED.

Question 4: What compression depth is recommended for an infant?

About 3 inches
About one-third the depth of the chest (about 1.5 inches) (Correct answer)
Exactly 2.4 inches
At least 2 inches

Correct answer: About one-third the depth of the chest (about 1.5 inches)

Infant compressions should be about one-third the chest depth, approximately 1.5 inches (4 cm).

Question 5: What is the recommended tidal volume for bag-valve-mask ventilation during CPR?

200-300 mL
500-600 mL (enough to produce visible chest rise) (Correct answer)
800-1,000 mL
1,000-1,200 mL

Correct answer: 500-600 mL (enough to produce visible chest rise)

Each breath should deliver approximately 500-600 mL (6-7 mL/kg), just enough to produce visible chest rise, avoiding gastric inflation.

Question 6: To minimize interruptions, compressions should be paused for no longer than how many seconds for breaths or other tasks?

About 30 seconds
No more than 10 seconds (Correct answer)
About 1 minute
As long as needed

Correct answer: No more than 10 seconds

Interruptions in compressions should be limited to less than 10 seconds to maintain blood flow.

Question 7: How long should you take to check for a pulse before starting compressions?

At least 30 seconds
A full 60 seconds
5 minutes
No more than 10 seconds (Correct answer)

Correct answer: No more than 10 seconds

Spend no more than 10 seconds checking a pulse to avoid delaying compressions.

Question 8: What compression depth is recommended for a child (age 1 to puberty) during CPR?

About 2 inches (5 cm) (Correct answer)
About 0.5 inch (1 cm)
About 1 inch (2.5 cm)
About 4 inches (10 cm)

Correct answer: About 2 inches (5 cm)

Child compressions should be about 2 inches, or one-third the depth of the chest.

Question 9: If pediatric AED pads are not available for a child under 8, what should you do?

Wait for EMS to bring pediatric pads
Use adult pads, ensuring they do not touch each other (Correct answer)
Do not use the AED at all
Cut the adult pads in half

Correct answer: Use adult pads, ensuring they do not touch each other

If pediatric pads are unavailable, use adult pads but make sure they do not touch each other on a small chest.

Question 10: Why is allowing full chest recoil between compressions important?

It prevents rib fractures
It lets the heart refill with blood (Correct answer)
It saves rescuer energy
It increases compression depth

Correct answer: It lets the heart refill with blood

Full recoil allows the heart to refill, improving blood flow on the next compression.

Question 11: How often may epinephrine be repeated during ongoing neonatal resuscitation?

Every 3 to 5 minutes if heart rate stays below 60 bpm (Correct answer)
Every 1 minute
Every 10 minutes
Only once

Correct answer: Every 3 to 5 minutes if heart rate stays below 60 bpm

Epinephrine doses may be repeated every 3 to 5 minutes while the heart rate remains below 60 bpm.

Question 12: If umbilical venous access is not yet available, what alternate route can be used for the first epinephrine dose?

Endotracheal tube (higher dose) (Correct answer)
Subcutaneous injection
Rectal administration
Oral administration

Correct answer: Endotracheal tube (higher dose)

Endotracheal epinephrine at a higher dose may be given while vascular access is being obtained, though it is less reliable.

Question 13: What is the recommended target temperature range for a newborn after birth?

34.0°C to 35.5°C
37.5°C to 38.5°C
35.0°C to 36.0°C
36.5°C to 37.5°C (Correct answer)

Correct answer: 36.5°C to 37.5°C

Newborn axillary temperature should be maintained between 36.5°C and 37.5°C to avoid hypo- and hyperthermia.

Question 14: At what heart rate threshold does the NRP recommend initiating positive-pressure ventilation (PPV) in a newborn?

Below 100 beats per minute with labored breathing or apnea (Correct answer)
Below 120 beats per minute
Below 60 beats per minute
Below 80 beats per minute

Correct answer: Below 100 beats per minute with labored breathing or apnea

PPV should be initiated if the newborn has apnea, gasping respirations, or a heart rate below 100 bpm after the initial steps.

Question 15: Where do you place pediatric AED pads if they must go front and back?

One on the center of the chest and one on the back (Correct answer)
One on each arm
Both on the back
Both on the front of the chest

Correct answer: One on the center of the chest and one on the back

On a small child, pads may be placed front and back (anterior-posterior) to avoid overlap.

Question 16: What is a common cause of ineffective chest compressions?

Using two hands instead of one
Counting compressions aloud
Compressing too slowly on purpose
Leaning on the chest and not allowing recoil (Correct answer)

Correct answer: Leaning on the chest and not allowing recoil

Leaning prevents full recoil, reducing how much blood the heart can pump.

Question 17: What is the first thing you should do before starting CPR on an unresponsive adult?

Check responsiveness and call for help/911 and an AED (Correct answer)
Begin compressions immediately without checking
Give two rescue breaths first
Check blood pressure

Correct answer: Check responsiveness and call for help/911 and an AED

Confirm unresponsiveness and activate emergency response to get help and an AED en route.

Question 18: What is 'hands-only CPR'?

Continuous chest compressions without rescue breaths (Correct answer)
CPR using only the AED
Compressions given with one finger
Rescue breaths without compressions

Correct answer: Continuous chest compressions without rescue breaths

Hands-only CPR uses continuous compressions and is recommended for untrained bystanders of adult cardiac arrest.

Question 19: What can happen if compressions are given too shallow?

The ribs heal faster
Over-oxygenation of the blood
The heart restarts too quickly
Insufficient blood flow to vital organs (Correct answer)

Correct answer: Insufficient blood flow to vital organs

Shallow compressions fail to circulate enough blood to the brain and heart.

Question 20: What does a Good Samaritan law generally provide in overdose situations?

Legal protection for bystanders who help in good faith (Correct answer)
A cash reward for every rescue
Free naloxone for life
Mandatory arrest of anyone present

Correct answer: Legal protection for bystanders who help in good faith

Good Samaritan laws protect people who provide reasonable emergency aid from liability.

Question 21: Which of the following opioid reversal routes is preferred for rapid emergency use by bystanders?

Intravenous (IV)
Intramuscular (IM) or intranasal (IN) (Correct answer)
Subcutaneous (SQ)
Oral (PO)

Correct answer: Intramuscular (IM) or intranasal (IN)

IM and intranasal routes are preferred for bystanders and first responders because no needles or IV access are required, allowing rapid administration.

Question 22: Where is intramuscular naloxone typically injected?

Outer thigh or upper arm muscle (Correct answer)
Directly into a vein in the neck
Into the heart
Into the abdomen

Correct answer: Outer thigh or upper arm muscle

IM naloxone is injected into a large muscle such as the thigh or upper arm.

Question 23: What should you do if a victim vomits after receiving naloxone?

Give another dose of naloxone right away
Turn them onto their side to clear the airway (Correct answer)
Sit them straight up immediately
Force them to swallow it back

Correct answer: Turn them onto their side to clear the airway

Rolling the victim onto their side prevents choking and aspiration of vomit.

Question 24: During CPR on an overdose victim, what is the correct compression-to-breath ratio for a single adult rescuer?

10 compressions to 5 breaths
15 compressions to 2 breaths
30 compressions to 2 breaths (Correct answer)
5 compressions to 1 breath

Correct answer: 30 compressions to 2 breaths

Single-rescuer adult CPR uses a 30:2 compression-to-ventilation ratio.
