Example Question #14 : Help With Respiratory Injuries And Disorders
A seven-year-old boy has an inflamed nasal mucous membrane, runny nose, nasal itching, nasal congestion, and sneezing. What is the term for his condition?
Rhinoplasty
Rhinalgia
Rhinitis
Rhinorrhea
Rhinitis
Rhinitis is an inflammation of the nasal mucous membrane which is accompanied by the symptoms present in the question. It is caused by allergies. In contrast, rhinorrhea is the scientific term for "runny nose." It is also associated with the common cold, flu, and allergies, and it is caused by tears draining into the inferior nasal meatus through the nasolacrimal duct. Rhinoplasty is a kind of plastic surgery that changes the size or shape of the nose (a "nose job"). Rhinalgia, also known as rhinodynia, is simply the term for "pain in the nose."
Example Question #15 : Help With Respiratory Injuries And Disorders
The lungs are enclosed in a membrane called the pleural membrane, which consists of the parietal pleura attached to the wall of the thoracic cavity and the visceral pleura, which covers the surface of the lungs. Between these two pleura is a space called the pleural space.
The presence of air in the pleural space is called __________.
pneumonia
pneumothorax
emphysema
laryngitis
bronchitis
pneumothorax
In a healthy lung, the fluid in the pleural space makes the visceral and parietal pleura to adhere to one another. If air enters this space from a rupture of the lung or chest wall injury, it is called a pneumothorax, which can lead to collapse of the lungs. Laryngitis is the inflammation of the larynx, or the voice box. Bronchitis is the inflammation of the bronchi, which are branches of the trachea leading to the lungs. Emphysema is a progressive lung disease that causes shortness of breath. Pneumonia is an infection of the alveoli that can be life-threatening.
Example Question #1 : Help With Evaluation Methods For The Heart
Multiple “sawtooth” P waves on an EKG suggest what pathology?
Atrial fibrillation
First degree atrioventricular (AV) block
Ventricular tachycardia
Atrial flutter
Premature ventricular contraction (PVC)
Atrial flutter
"Sawtooth" P waves are characteristic of atrial flutter.
Example Question #1 : Help With Evaluation Methods For The Heart
You are looking at your patient's EKG, and you suspect he may be experiencing a first degree atrioventricular (AV) block. What EKG findings would lead you to this conclusion?
Multiple QRS complexes prior to a P wave
“Sawtooth” shaped P waves
Multiple P waves prior to the QRS complex
Absent P wave
Prolonged P-R interval
Prolonged P-R interval
A prolonged P-R interval, that does not get progressively longer is typical of a type I A-V block.
Example Question #2 : Help With Evaluation Methods For The Heart
What does an inverted or absent P wave (as an early beat) represent?
Premature junctional/nodal beat
Premature ventricular contraction
Bundle branch block
Paroxysmal atrial tachycardia
Premature atrial beat
Premature junctional/nodal beat
A premature junctional/nodal beat would be represented on an ECG as an inverted or absent P wave. In a premature junctional/nodal beat, the atrioventricular (AV) node is firing before the sinoatrial (SA) node. Since the AV node is at the bottom of the right atrium, the net vector of atrial depolarization is occurring in a more upward direction, causing the P wave to be absent or inverted. Note that there would be a compensatory pause after the premature beat.The answer could not be a premature atrial contraction because the P wave is absent or inverted (P wave would be normal in a premature atrial contraction (PAC)).
Example Question #3 : Help With Evaluation Methods For The Heart
Which of the following conditions is the most serious?
First degree AV block
Ventricular fibrillation
Bundle branch block
Third degree AV block
Atrial fibrillation
Ventricular fibrillation
Ventricular fibrillation is a very serious issue that requires immediate defibrillation. Ventricular fibrillation is the result of ventricular beats originating from many different automaticity foci, so the QRS looks squiggly, very fast, and incoherent. There are no P waves since the beats are originating in the ventricles.
Example Question #4 : Help With Evaluation Methods For The Heart
Which of the following is a difference between Bundle Branch Block (BBB) and a Premature Ventricular Contraction (PVC)?
None of these
BBB has a P wave, PVC does not
PVC has a P wave, BBB does not
PVC has a wide QRS, PVC does not
BBB has a wide QRS, PVC does not
BBB has a P wave, PVC does not
A bundle branch block is a block in one of the bundle branches, causing a long QRS (>.10 seconds). It is different than a PVC in that a bundle branch block will show a P wave since the beats are still originating in the atria. Bundle Branch Blocks also tend to show a notched QRS.
Example Question #5 : Help With Evaluation Methods For The Heart
Which AV block is characterized by a longer than normal PR interval (of consistent length)?
Second Degree AV Block, Mobitz Type 2
All of these
Second Degree AV Block, Mobitz Type 1 (Wenckebach)
First Degree AV Block
Third Degree AV Block
First Degree AV Block
In First Degree AV Block, there is a longer than normal PR interval (>.20s) due to slowed AV node conduction. Second degree, Mobitz Type 1 (Wenckebach) is progressive lengthening of the PR interval followed by a dropped QRS. Second Degree, Mobitz Type 2 is sudden dropping of the QRS (no lengthening of PR interval). Third Degree AV Block is when there is no relationship between the P and the QRS.
Example Question #6 : Help With Evaluation Methods For The Heart
What is a normal PR interval length?
.22 seconds
.06 seconds
.10 seconds
.14 seconds
.24 seconds
.14 seconds
The normal PR interval length is .12 - .20 seconds. The PR interval represents the time lag from the onset of atrial depolarization to the onset of ventricular depolarization. Most of the time lag occurs in the AV node, and it allows atrial systole to occur. This allows the ventricles to have time to fill before ventricular systole.
Example Question #44 : Circulatory And Respiratory Systems
What is the criteria for tachycardia?
>120 beats/minute
>100 beats/minute
<80 beats/minute
>90 beats/minute
<60 beats/minute
>100 beats/minute
Tachycardia is an abnormally rapid heart rate of rate >100 beats per minute.
