The S1 heart sound is caused by closure of the:
-
Tricuspid valve and aortic valve
-
Semilunar valves
-
Atrioventricular valves
-
Nitral valve and pulmonic valve
Correct Answer
A. Atrioventricular valvesExplanation
The S1 heart sound, also known as the "lub" sound, is caused by the closure of the atrioventricular valves (the tricuspid valve and the mitral valve). These valves separate the atria from the ventricles and prevent the backflow of blood into the atria when the ventricles contract. The closure of these valves produces a sound that can be heard with a stethoscope. The semilunar valves (aortic valve and pulmonic valve) are responsible for the S2 heart sound, also known as the "dub" sound, which occurs when these valves close at the end of ventricular contraction.Rate this question:

When a myocardial fiber is at rest the charge within the cell is:
-
Polarized
-
Negative
-
Depolarized
-
Positive
Correct Answer
A. NegativeExplanation
When a myocardial fiber is at rest, the charge within the cell is negative. This is because the cell is in a polarized state, meaning that there is a difference in electrical charge between the inside and outside of the cell. The inside of the cell is more negatively charged compared to the outside. This state of polarization allows for the proper functioning of the cell and is important for the transmission of electrical signals in the heart.Rate this question:

The presence of S3 heart sounds is associated with:
-
Cardiac tamponade
-
Aortic aneurysm
-
Bundle branch block
-
Congestive heart failure
Correct Answer
A. Congestive heart failureExplanation
The presence of S3 heart sounds is associated with congestive heart failure. S3 heart sounds are caused by a rapid rush of blood into a dilated ventricle during the early phase of diastole. In congestive heart failure, the heart is unable to effectively pump blood, leading to an accumulation of fluid in the lungs and an enlarged ventricle. This results in the presence of S3 heart sounds, which can be detected during a physical examination using a stethoscope.Rate this question:

Which factor is common to all forms of shock?
-
Inadequate tissue perfusion
-
Tachypnea
-
Hypovolemia
-
Tachycardia
Correct Answer
A. Inadequate tissue perfusionExplanation
Inadequate tissue perfusion is a common factor in all forms of shock. Shock is a condition where there is insufficient blood flow to the body's organs and tissues, leading to cellular dysfunction and organ failure. Inadequate tissue perfusion means that the organs and tissues are not receiving enough oxygen and nutrients due to reduced blood flow. This can occur in various types of shock, including hypovolemic shock (caused by severe blood or fluid loss), cardiogenic shock (caused by heart failure), and septic shock (caused by severe infection). In all these forms of shock, the underlying problem is inadequate tissue perfusion.Rate this question:

-
Pulse difference
-
Pulse deficit
-
Circulatory gap
-
Pulsis paradoxis
Correct Answer
A. Pulse deficitExplanation
A pulse deficit occurs when there is a difference between the apical pulse rate and the radial pulse rate. In this case, the apical pulse rate is 130 and the radial pulse rate is 96, indicating a pulse deficit of 34. This can be caused by various factors such as irregular heart rhythms or poor circulation. Monitoring and addressing pulse deficits is important as it can be an indication of cardiovascular issues and may require further medical intervention.Rate this question:

Stimulation of the beta receptors causes:
-
Bronchial constriction and tachycardia
-
Increased heart rate and force of contraction
-
Increased vasular resistance and vasocontriction
-
Decreased cardiac oxygen consumption
Correct Answer
A. Increased heart rate and force of contractionExplanation
Stimulation of the beta receptors in the body leads to an increase in heart rate and force of contraction. Beta receptors are found in the heart and when they are activated, they cause the heart to beat faster and with more force. This results in an increased cardiac output, which is the amount of blood pumped by the heart per minute. The increased heart rate and force of contraction help to meet the body's increased demand for oxygen and nutrients during periods of stress or exercise.Rate this question:

You have been ordered to give a patient 7 mcg/min of isuprell. Mix 1 mg in 250 ml of D5W and use a microdrip. What drip rate is needed?
-
28 gtts/min
-
90 gtts/min
-
105 gtts/min
-
210 gtts/min
Correct Answer
A. 105 gtts/minExplanation
To calculate the drip rate, we need to convert the dosage from mcg/min to mg/min. Since 1 mg is mixed in 250 ml of solution, we can calculate the concentration of the solution as 1 mg/250 ml = 0.004 mg/ml.
Next, we need to convert mg/min to ml/min by dividing the dosage (7 mcg/min) by the concentration (0.004 mg/ml). This gives us a result of 1750 ml/min.
Since we are using a microdrip, the drip factor is usually 60 gtts/ml. Therefore, we can calculate the drip rate by multiplying the ml/min (1750 ml/min) by the drip factor (60 gtts/ml). This gives us a result of 105, which means a drip rate of 105 gtts/min is needed.Rate this question:

-
0.4-0.12
-
0.2-0.4
-
0.1-0.20
Correct Answer
A. 0.12-0.20Explanation
The normal PR interval is 0.12-0.20 seconds. This is the standard range of time it takes for an electrical signal to travel from the atria to the ventricles in the heart.

-
10-20 mins
-
20-40 min
-
40-60 min
-
60-70 min
Correct Answer
A. 20-40 minExplanation
The Purkinje system is a network of specialized cells in the heart that helps regulate its electrical activity. These cells have an intrinsic firing rate, which means they can generate electrical impulses on their own. The correct answer of 20-40 min suggests that the Purkinje system typically fires at a rate of once every 20 to 40 minutes. This firing rate is important for maintaining a regular heart rhythm and ensuring efficient pumping of blood throughout the body.Rate this question:

A possible complication of the PASG is:
-
Increased bleeding under the suit
-
Decreased ventilation
-
Gastric dilatation
-
Reduced venous return to the heart
Correct Answer
A. Decreased ventilationExplanation
The possible complication of the PASG (Pneumatic Anti-Shock Garment) is decreased ventilation. This means that wearing the PASG can hinder the ability to breathe properly. The garment may restrict the movement of the chest and abdomen, making it difficult for the person to take in an adequate amount of air. This can lead to respiratory distress and potentially worsen the patient's condition. It is important to monitor the patient's breathing and ensure that the PASG is not causing any respiratory complications.Rate this question:

Which of the following is a result of a serious insulin deficit?
-
Metabolic acidosis
-
Respiratory alkalosis
-
Respiratory acidosis
-
Metabolic alkalosis
Correct Answer
A. Metabolic acidosisExplanation
A serious insulin deficit can lead to metabolic acidosis. Insulin is responsible for regulating glucose levels in the blood. Without enough insulin, glucose cannot enter the cells for energy production, leading to increased fat breakdown and the production of ketones. Ketones are acidic byproducts that accumulate in the blood, causing a decrease in blood pH and resulting in metabolic acidosis. Symptoms of metabolic acidosis include rapid breathing, confusion, and fatigue.Rate this question:

Which of the following is the earliest sign of shock?
-
Hypotension
-
Restlessness
-
Cyanosis
-
Cool clammy skin
Correct Answer
A. RestlessnessExplanation
Restlessness is the earliest sign of shock because it is the body's natural response to decreased blood flow and oxygenation. When the body is in shock, it tries to compensate by increasing heart rate and respiratory rate, causing the person to feel restless and anxious. This is a crucial early warning sign that indicates the body's attempt to maintain adequate blood flow and oxygenation. Hypotension, cyanosis, and cool clammy skin are all later signs that occur as shock progresses and the body's compensatory mechanisms become overwhelmed.Rate this question:

Airway obstruction can be caused by:
-
Dorsal flexion
-
Lateral extension
-
Ventral flexion
-
Ventral extension
Correct Answer
A. Ventral flexionExplanation
Ventral flexion refers to the bending of the body or body part towards the front or belly side. In the context of airway obstruction, ventral flexion can cause narrowing or closure of the airway, leading to difficulty in breathing. This can occur when the muscles or structures in the front of the airway collapse or compress the airway, obstructing the flow of air. Therefore, ventral flexion is a potential cause of airway obstruction.Rate this question:
