Cardac output A mother of a child with a heart disease asks the nurse what a right to left shunt refers to. The best response from the nurse would be? IE s a passageway that diverts blood from its normal drauletory e The pumping of blood from the right to the keft side of the It is a shunt that aways results to cyanoss heart through the ventricular septal defect The pumping of the blood from the left to right side of the heart through a hole between the atria Which of the following characteristics of blood is correct Select all that apply Three to five times more vicous than water Oxygen-poor blood is blue-red 16. Amount not affected by body stae, gender, and age Viscosity can luctuate widely aNormal phH is 7.35-745 The cardiac impulse rate of sinoatrial node is? 50 to 60 375 to 100 70 to 85 4 60 to 100 A dlient with a heart disease is taking a vagomimetic drug. The client asks the nurse," What is a vagomimetic drug?" What of the following responses from the nurse is most appropriate? It "mimics the vagal stimulation It is a drug that dilates the coronary artery 18. It blocks the effect of vagal stimulation It is a drug that "mimics" the aspirin When there is excessive breakdown of these blood cells, the patient may present with jaundice Red blood cells Platelets Lymphocytes An example of a connective tissue that has a liquid intercellular matrix is 20. Blood

Answer 1

15. The pumping of blood from the right to left side of the heart through the ventricular septal defect.

• right to left shunt is a type of cardiac shunt, oxygen poor blood flows from the right side to left side of the heart and this deoxygenated blood enters the circulatory system which can cause cyanosis like defects.

16. 3 to 5 times more viscous than water, oxygen poor blood is blue-red, amount not affected by body size, gender and age, normal pH 7.35 - 7.45

• Blood in artery contains oxygenated blood which appears as red color and blood in vein contains impure or deoxygenated blood which appears as blue in color. The blood in vein have high carbon dioxide content.
• A healthy average adult has about 4.5 to 5.5 litres of blood, it may vary with respect to diseases but amount does not depends on age, size or gender of a human.

17. Cardiac impulse rate of sinoatrial (SA) node is 60-100 beats per minute (bpm)

• It is located on the hearts right atrial wall, which is also called as pacemaker.
• All of the cardiac impulses are originated from the sinoatrial node orninus node.

18. It mimics the vagal stilulation

• It deliver electric impulse to the vagus nerve which is used in treating migraines and epilepsy.
• It is also involved in parasympathetic control of heart, digestive system, and lungs

19. Red blood cells.

• Jaundice is caused by excessive break down of red blood cells which results in formation of bilirubin in blood.
• Thus the increased level of bilirubin causes jaundice.
• Jaundice is only a symptom which may be due to a liver disease.

20. blood

• Type of connective tissue with liquid intercellular matrix that is what called plasma.
• Constitute 55% of total blood volume in a body.
• Plasma is a yellowish component which contain water, proteins, enzymes, etc.
