Integumentary System Changes: What is common?

A

Striae gravidarum (stretch marks) are common on the breasts, abdomen, and thighs.

82
Q

Striae gravidarum

A

(stretch marks)

83
Q

How does Striae gravidarum appear initially?

A

Striae gravidarum may initially appear dark or red and then become paler or silvery over time.

84
Q

Integumentary System Changes: What is often found on the skin of darker skinned patients?

A

Linea nigra, a dark line from the pubic symphysis to the fundus, is more often found in pregnant patients with darker skin and gradually disappears after pregnancy.

85
Q

Integumentary System Changes: What happens to moles, freckles and areolae during pregnancy?

A

Nevi (moles), macules (freckles), and areolae darken.

86
Q

Integumentary System Changes: Having to do with skin tone, what changes during pregnancy?

A

Chloasma (also known as the mask of pregnancy) darkens with sun exposure and disappears after pregnancy.

87
Q

Integumentary System Changes: What happens to blood vessels during pregnancy?

A

Blood vessels dilate and become more prominent in early pregnancy due to increased estrogen levels.

88
Q

Integumentary System Changes: Palmar erythema

A

Palmar erythema is caused by increased blood flow and is harmless and painless.

Is increased blood flow to the hands

89
Q

Integumentary System Changes: How is the hair during pregnancy?

A

Hair grows longer and thicker in pregnancy due to estrogen stimulating the hair follicles.

Body hair tends to be more course and abundant after pregnancy.

90
Q

Integumentary System Changes: When does hair growth return to normal?

A

Hair growth returns to normal during the first 4 months after delivery.

91
Q

Integumentary System Changes: How are nails during pregnancy?

A

Nails may become softer, harder, or more brittle during pregnancy.

92
Q

Respiratory System Changes: How is oxygen consumption during pregnancy?

A

Oxygen consumption increases 15% to 20% during pregnancy.

93
Q

Respiratory System Changes: How is tidal volume during pregnancy?

A

Tidal volume, or the amount of air exchanged in respiration, increases 40% to 50%.

94
Q

Respiratory System Changes: Why would a pregnant person be in a state of physiological respiratory alkalosis?

A

Mild hyperventilation and sense of dyspnea results in a state of physiological respiratory alkalosis.

Patient who is pregnant “blows off” more CO2 than normal allowing for CO2 in fetal circulation to diffuse into the maternal blood stream while O2 diffuses to the fetus.

95
Q

Respiratory System Changes: How is the diaphragm of a pregnant person?

A

Diaphragm elevates approximately 5 cm during pregnancy, to accommodate this change, ribs expand and the subcostal angle increases.

96
Q

Respiratory System Changes: What would cause congestion of mucous membranes in pregnant persons?

A

Increased estrogen causes congestion of mucous membranes.

97
Q

Respiratory System Changes: Congestion of mucous membranes in pregnant people can cause what?

A

This congestion can cause swelling of pharynx, trachea, larynx, while engorged capillaries may cause frequent nose bleeds.

98
Q

Cardiovascular System Changes: How is cardiac output of pregnant person?

A

Cardiac output increases by as much as 50%.

99
Q

Cardiovascular System Changes: What do hormones do to peripheral vascular resistance?

A

Hormones in pregnancy reduce peripheral vascular resistance to compensate for increased blood volume.

100
Q

Cardiovascular System Changes: What happens to blood volume? What does this result in?

A

Total blood volume increases by 40% to 45% while red blood cell count increases by 30%. Result is physiological anemia of pregnancy.

101
Q

Cardiovascular System Changes: What happens to wbc during pregnancy?

A

White blood cell count increases during pregnancy and may not indicate infection.

102
Q

Cardiovascular System Changes: What is thought to prevent excessive postpartum bleeding in pregnancy?

A

Rise in fibrinogen and other clotting factors thought to prevent excessive postpartum bleeding puts pregnant persons at risk for blood clots, which could lead to pulmonary embolism or stroke.

103
Q

Cardiovascular System Changes: What puts pregnant persons at risk for blood clots?

A

Rise in fibrinogen and other clotting factors thought to prevent excessive postpartum bleeding puts pregnant persons at risk for blood clots, which could lead to pulmonary embolism or stroke.

Cardiovascular System Changes: What happens to heart sounds during pregnancy?

A

Temporary changes in heart sounds are common and benign in pregnancy.

105
Q

Urinary System Changes: How is blood flow to and through kidneys during pregnancy?

A

Blood flow to and through the kidneys increases by 80% during pregnancy.

106
Q

Urinary System Changes: How is glomerular filtration rate during pregnancy?

A

Glomerular filtration rate increases about 50% during pregnancy.

107
Q

Urinary System Changes: What is not uncommon in urine during pregnancy?

A

Not uncommon for persons who are pregnant to spill small amounts of glucose and protein into the urine.
