Question 10. Question : Which statement is true concerning the IgM?

IgM is the first antibody produced during the initial response to an antigen.

IgM mediates many common allergic responses.

IgM is the most abundant class of immunoglobulins.

Question 11. Question : An infant has a loud, harsh, holosystolic murmur and systolic thrill that can be detected at the left lower sternal border that radiates to the neck. These clinical findings are consistent with which congenital heart defect?

Atrial septal defect (ASD)

Ventricular septal defect (VSD)

Question 12. Question : What is the chief predisposing factor for respiratory distress syndrome (RDS) of the newborn?

Low birth weight

Alcohol consumption during pregnancy

Premature birth

Smoking during pregnancy

Question 13. Question : Which cardiac chamber has the thinnest wall and why?

The right and left atria; they are low-pressure chambers that serve as storage units and conduits for blood.

The right and left atria; they are not directly involved in the preload, contractility, or afterload of the heart.

The left ventricle; the mean pressure of blood coming into this ventricle is from the lung, which has a low pressure.

The right ventricle; it pumps blood into the pulmonary capillaries, which have a lower pressure compared with the systemic circulation.

Sodium retention

Sodium excretion

Water retention

Water excretion
