Some pregnant patients may complain of changes in their voice and impaired hearing. The nurse can tell these patients that these are common reactions to:
a. A decreased estrogen level.
b. Displacement of the diaphragm, resulting in thoracic breathing.
c. Congestion and swelling, which occur because the upper respiratory tract has be-come more vascular.
d. Increased blood volume.
C
Feedback
A Estrogen levels increase, causing the upper respiratory tract to become more vascular; this produces swelling and congestion in the nose and ears and there-fore voice changes and impaired hearing.
B The diaphragm is displaced. However, the key is that estrogen levels increase, causing the upper respiratory tract to become more vascular; this produces swel-ling and congestion in the nose and ears and therefore voice changes and im-paired hearing.
C Estrogen levels increase, causing the upper respiratory tract to become more vascular; this produces swelling and congestion in the nose and ears and there-fore voice changes and impaired hearing.
D The volume of blood is increased. However, the key is that estrogen levels in-crease, causing the upper respiratory tract to become more vascular; this pro-duces swelling and congestion in the nose and ears and therefore voice changes and impaired hearing.
