Blooket Question Set - Answer Key

These flashcards cover key concepts from the Blooket question set related to blood physiology, EKG interpretation, and patient care in cardiology.

Hemoglobin

The protein that carries oxygen and returns carbon dioxide in the blood.

Components of blood

The four main components of blood are Red Blood Cells (RBC), White Blood Cells (WBC), plasma, and platelets.

Vena cava

The vessel that brings deoxygenated blood to the heart.

Location of hemoglobin

Hemoglobin is found in red blood cells.

Universal donor blood type

O- is considered the universal donor blood type.

Aorta

The vessel that carries oxygenated blood from the heart to the body.

SA node normal rate

The normal rate of the SA node is between 60-100 beats per minute.

Ventricles

The ventricles are the thick muscular pumping chambers of the heart that pump blood into arteries.

Diffusion of oxygen location

Diffusion of oxygen occurs in the capillaries.

Leading cause of death in the US

The leading cause of death in the US is heart disease.

Electrical malfunction of the heart

An irregular heartbeat due to electrical malfunction is called cardiac arrest.

Myocardial infarction

Blocked blood flow to the heart causes a myocardial infarction.

Aorta and oxygen-depleted blood

The statement that the aorta carries oxygen-depleted blood is FALSE.

AV node function

The AV node slows the signal to the ventricles.

Pulmonary artery function

The function of the pulmonary arteries is to carry blood away from the heart to the lungs.

Bicuspid valve

The bicuspid valve is also called the mitral valve.

Diastole

The heart fills with blood during diastole.

HIPAA compliance

HIPAA compliance includes keeping diagnosis information private and not disclosing ID numbers.

Reduce child anxiety for EKG

One way to reduce child anxiety for an EKG is to touch the equipment.

Stress test result communication

The cardiologist communicates the results of a stress test.

Correct patient identification method

The correct method for patient identification is to use name and date of birth.

Disinfecting leads frequency

Leads should be disinfected after each use.

Reduce tremor artifact

To reduce tremor artifact, patients can be instructed to put their hands under their buttocks.

Lead V4 placement

Lead V4 is placed at the midclavicular line in the 5th intercostal space (ICS).

Ground electrode location (Holter)

The ground electrode for a Holter monitor should be placed on the left lower abdomen.

Emergency symptoms during stress test

Symptoms like syncope during a stress test are considered emergencies.

Pulse oximeter measurement

A pulse oximeter measures oxygen saturation in the blood.

Continuous inpatient monitoring

Continuous inpatient monitoring is achieved through telemetry.

Cleaning skin before electrodes

Skin should be cleaned with alcohol wipes before placing electrodes.

Double height of tracing

To double the height of an ECG tracing, set it to 20 mm/mV.

Lead V1 placement

Lead V1 is placed in the 4th ICS at the right sternal border.

Small box duration on EKG

A small box on the EKG represents 0.04 seconds.

Counting ventricular rate

Ventricular rate is determined by counting the R waves.

Atrial contraction wave

The atrial contraction wave is represented by the P wave.

Ventricular contraction wave

The ventricular contraction wave is represented by the QRS complex.

Fast heart rate term

A fast heart rate greater than 100 bpm is called tachycardia.

60-cycle interference

60-cycle interference is a type of artifact caused by other electrical equipment.

Ventricular depolarization representation

Ventricular depolarization is represented by the QRS wave.

Dysrhythmias without pulse

Atrial fibrillation and ventricular fibrillation are dysrhythmias that do not produce a pulse.

Standard EKG paper speed

The standard speed of EKG paper is 25 mm/sec.

Large square duration on EKG

One large square on the EKG captures 0.20 seconds.

Checking EKG validity

To check EKG validity, look for a standardization mark that is 10 mm high.

Red limb lead placement

The red limb lead should be placed on the left arm.

Standard calibration box size

A standard calibration box on the EKG measures 10 mm x 5 mm.

Holter monitor instructions during palpitations

If experiencing palpitations while wearing a Holter monitor, the patient should press the event button.
