44
Q

Physiological status of pregnant client: What goes on reproductively?

A

Uterus increases in size and changes shape and positions

Ovulation and menses cease during pregnancy

45
Q

Physiological status of pregnant client: What happens to the cardiovascular system?

A

CO and blood volume increase (45-50% at term) to meet the greater metabolic needs; HR increases

46
Q

Physiological status of pregnant client: What happens with respiratory?

A

Maternal oxygen needs increase

During last trimester, the size of the chest may enlarge allowing for lung expansion and the uterus pushes upward

RR increases and total lung capacity decreases

47
Q

Physiological status of pregnant client:

What happens in the musculoskeletal system?

A

Body alterations and weight increase necessitate an adjustment to posture; pelvic joints relax

48
Q

Physiological status of pregnant client:

What happens with GI?

A

N/V and constipation

49
Q

Physiological status of pregnant client:

What happens in the renal system?

A

Filteration rate increases secondary to the influence of preg. hormones and an increase in blood volume and metabolic demands

Amount of urine remains the same, but urinary frequency is common

50
Q

Physiological status of pregnant client:

What happens in the endocrine system?

A

The placenta becomes an endocrine organ–hormones are very active in pregnancy

51
Q

Physiological status of pregnant client:

Body image changes?

A

First trimester= not obvious–many women look forward to the changes of pregnancy to become more noticable

2nd trimester= enlargement of abdomen and breasts; skin changes (stretch marks, hyper pigmentation); back, leg discomfort and fatigue–> all lead to negative body image and the woman ready for pregnancy to be over

52
Q

How is BP like in first tri?

A

Within pre-pref range

53
Q

How is BP during 2nd tri?

A

Decreases 5-10 mmHg for both diastolic and systolic

54
Q

When should BP return to pre pregnancy baseline range?

A

Approx. 20 weeks gestation

55
Q

Why should preg woman not lay supine?

A

Affect BP–BP may be lower due to weight and pressure of uterus on the vena cava–this decreases blood flow to the heart—maternal hypotension and fetal hypoxia can occur

56
Q

What are signs of supine hypotensive syndrome/supine vena cava syndrome?

A

Dizziness
Lightheadedness
Pale, clammy skin

57
Q

What positions should we encourage the mom to be in when resting to prevent maternal hypotension and fetal hypoxia?

A

Left lateral side
Semi-fowlers
If supine, put a wedge under one hip to alleviate pressure to vena cava

58
Q

When does pulse increase? Does it stay elevated or decline back down for the remainder of pregnancy?

A

Increases 10-15/min around 20 weeks; it remains elevated

59
Q

How much do respirations increase by?

A

1-2/MIN

60
Q

What is normal fetal heart beat?

A

110-160, with reassuring FRH accelerations noted, which indicates an intact fetal CNS

61
Q

By 36 weeks gestation, the top of the uterus and the funds will reach the ____

A

Xiphoid process–this may cause preg woman to experience SOB as uterus pushes against diaphragm

62
