HEART CHAMBERS-NAME THE FOUR CHAMBERS
- A.
ATRIA
- B.
SEPTUM
- C.
VENTRICLES
- D.
TRICUSPID
- E.
PERICARDIAL
Correct Answer(s)
A. ATRIA
C. VENTRICLESExplanation
The correct answer is ATRIA and VENTRICLES. The atria are the two upper chambers of the heart, responsible for receiving blood from the body and lungs. The ventricles are the two lower chambers of the heart, responsible for pumping blood out to the body and lungs. The other terms mentioned in the question, such as septum, tricuspid, and pericardial, are not chambers of the heart but rather refer to other structures or components of the heart.Rate this question:

WHAT ARE THE FOUR FACTORS THAT EFFECT BLOOD PRESSURE?
- A.
HEART ACTION
- B.
BLOOD VOLUME
- C.
RESISTANCE TO BLOOD FLOW
- D.
VISCOSITY OF THE BLOOD
- E.
ALL OF THE ABOVE
Correct Answer(s)
A. HEART ACTION
B. BLOOD VOLUME
C. RESISTANCE TO BLOOD FLOW
D. VISCOSITY OF THE BLOOD
E. ALL OF THE ABOVEExplanation
The correct answer is "HEART ACTION, BLOOD VOLUME, RESISTANCE TO BLOOD FLOW, VISCOSITY OF THE BLOOD, ALL OF THE ABOVE." These four factors are known to affect blood pressure. The heart's pumping action determines the force at which blood is pushed through the arteries, thus impacting blood pressure. Blood volume refers to the amount of blood in the body, and an increase in blood volume can lead to higher blood pressure. Resistance to blood flow occurs when the arteries are narrowed or constricted, making it harder for blood to flow through, resulting in increased blood pressure. Viscosity of the blood refers to its thickness or resistance to flow, and higher viscosity can contribute to higher blood pressure. Therefore, all of these factors play a role in determining blood pressure levels.Rate this question:

SA NODE, AV, NODE, BUNDLE OF HIS CAN BE VIEWED BY WHAT LEADS ON THE RIGHT SIDE OF THE HEART?
Correct Answer(s)
V1 AND V2Explanation
The SA node, AV node, and Bundle of His are all located in the right atrium of the heart. Leads V1 and V2 are placed on the right side of the heart and provide a view of the electrical activity in this area. Therefore, these leads can be used to visualize the SA node, AV node, and Bundle of His.Rate this question:
- 4.
LEADS V3 AND V4 VIEW THIS OF THE HEART
Correct Answer(s)
RIGHT AND LEFT BUNDLE BRANCHES, AND TOP OF THE INTERVENTRICULARS SEPTUMExplanation
This answer is correct because leads V3 and V4 provide a view of the heart's right and left bundle branches, as well as the top of the interventricular septum. These leads are typically placed on the anterior chest wall and provide a specific perspective on the electrical activity and conduction system of the heart.Rate this question:
- 5.
LEADS V5 AND V6 VIEW.....
Correct Answer(s)
OVER LEFT VENTRICLE, VIEW OF THE APEX POINT OF THE HEART LOWEST POINT OF THE HEART.Explanation
The correct answer is "OVER LEFT VENTRICLE, VIEW OF THE APEX POINT OF THE HEART, LOWEST POINT OF THE HEART." This answer accurately describes the location and view of the apex point of the heart, which is the lowest point of the heart, as seen in leads V5 and V6.Rate this question:

ATRIAL FLUTTER
- A.
SA NODE SENDS SIGNALS RAPIDLY 250-350 BEATS PER MIN
- B.
AV NODE CANNOT KEEP UP
- C.
SEVERAL SAW-TOOTH -P- WAVES.
- D.
OCCASIONAL QRS COMPLEXES
- E.
ALL OF THE ABOVE
Correct Answer(s)
A. SA NODE SENDS SIGNALS RAPIDLY 250-350 BEATS PER MIN
B. AV NODE CANNOT KEEP UP
C. SEVERAL SAW-TOOTH -P- WAVES.
D. OCCASIONAL QRS COMPLEXES
E. ALL OF THE ABOVEExplanation
The correct answer explains that in atrial flutter, the SA node sends signals rapidly at a rate of 250-350 beats per minute, which is faster than the AV node can keep up with. This results in several saw-tooth P-waves on the ECG. Occasionally, QRS complexes may be seen, but not consistently. Therefore, all of the above options are correct in describing atrial flutter.Rate this question:

ATRIAL FIBRILLATION HAS THESE SYMPTOMS..
- A.
350-600 BEATS PER MINUTE
- B.
INEFFECTIVE CONTRACTIONS OF ATRIA
- C.
SMALL NUMBER OF IMPULSES REACH THE VENTRICLES
- D.
NOT COMPATIBLE WITH LIFE
- E.
ALL OF THE ABOVE
Correct Answer(s)
A. 350-600 BEATS PER MINUTE
B. INEFFECTIVE CONTRACTIONS OF ATRIA
C. SMALL NUMBER OF IMPULSES REACH THE VENTRICLES
E. ALL OF THE ABOVEExplanation
The correct answer is "ALL OF THE ABOVE". Atrial fibrillation is a condition characterized by rapid and irregular heartbeats, ranging from 350 to 600 beats per minute. This rapid rate leads to ineffective contractions of the atria, which can result in a small number of impulses reaching the ventricles. If left untreated, atrial fibrillation can be life-threatening. Therefore, all of the symptoms mentioned in the question are associated with atrial fibrillation.Rate this question:

SINUS TACHYCARDIA , HAS NORMAL SINUS RHYTHM AND
- A.
100-170 BPM
- B.
170-200 BPM
- C.
200-250 BPM
- D.
300- 350 BPM
- E.
100-160 BEATS
Correct Answer
E. 100-160 BEATSExplanation
The correct answer is 100-160 BEATS. Sinus tachycardia refers to a faster than normal heart rate originating from the sinus node. A normal sinus rhythm typically falls within the range of 60-100 beats per minute. In the case of sinus tachycardia, the heart rate is elevated but still within a relatively normal range, specifically between 100-160 beats per minute.Rate this question:

SINUS BRADYCARDIA, HAS....
- A.
NORMAL SINUS RHYTHM, HEART RATE OF 100 BPM
- B.
NORMAL SINUS RHYTHM BUTSLOW HEART RATE OF LESS THAN 60 BPM
- C.
NORMAL SINUS RHYTHM HEART RATE OF 200 BPM
- D.
IRREGULAR SINUS RHYTHM , HEART RATE OF 350-
- E.
NONE OF THE ABOVE
Correct Answer
B. NORMAL SINUS RHYTHM BUTSLOW HEART RATE OF LESS THAN 60 BPMExplanation
The correct answer is "NORMAL SINUS RHYTHM BUT SLOW HEART RATE OF LESS THAN 60 BPM". Sinus bradycardia refers to a condition where the heart rate is slower than normal (less than 60 beats per minute) but maintains a regular rhythm. This can be caused by factors such as certain medications, underlying heart conditions, or increased vagal tone. It is important to monitor and evaluate the underlying cause of sinus bradycardia to determine appropriate treatment.Rate this question:

ATRIAL TACHYCARDIA HAS...
- A.
SA NODE IS STILL DOMINENT, 200-250
- B.
SA NODE IS NO LONGER , DOMINENT PACEMAKER
- C.
RAPID HEART RATE, ATRIA DEPOLARIZING, DURING VENTRICULAR REPOLARIZATION
- D.
INTERMITTENT PROBLEM THAT OFTEN ENDS ABRUPTLY
- E.
160-250
Correct Answer(s)
B. SA NODE IS NO LONGER , DOMINENT PACEMAKER
C. RAPID HEART RATE, ATRIA DEPOLARIZING, DURING VENTRICULAR REPOLARIZATION
D. INTERMITTENT PROBLEM THAT OFTEN ENDS ABRUPTLY
E. 160-250Explanation
Atrial tachycardia is characterized by a rapid heart rate, with the atria depolarizing during ventricular repolarization. In this condition, the SA node is no longer the dominant pacemaker, meaning that it is not controlling the heart rate as it should. Atrial tachycardia is an intermittent problem that often ends abruptly. The heart rate during atrial tachycardia typically falls within the range of 160-250 beats per minute.Rate this question:
