RNC-OB Exam: Cardiac with all Correct & 100% Verified
Answers |Latest Update |Already Graded A+
What does cardiac output do in pregnancy? ✔Correct Answer-Increase
What does stroke volume do in pregnancy? ✔Correct Answer-Increase
What does HR do in pregnancy? ✔Correct Answer-Increase
What does vascular resistance do in pregnancy? ✔Correct Answer-Decrease
What happens when cardiac output decreases during pregnancy? ✔Correct Answer-IUGR due
to decreased nourishment
Most common underlying cause of maternal cardiac disease? ✔Correct Answer-Rheumatic
heart disease
Increased Risks due to Cardiac Disease ✔Correct Answer-- MI
- CHF
- Pulmonary edema
- HTN
Stroke Volume ✔Correct Answer-The amount of blood pumped with each beat
What does stroke volume effect? ✔Correct Answer-Perfusion to uterine arteries and thus
fetal perfusion (remember the uterus is not a vital organ = less perfusion...blood is shunted
away from uterus to save vital organs)
How does pre-e effect stroke volume? ✔Correct Answer-Due to all the pressure and duration
of time, stroke volume is decreased which results in oligohydramnios to fetus
What does plasma volume do in pregnancy? ✔Correct Answer-Increases up to 60% which
increased the workload on heart which can lead to CHF
How much does cardiac output increase in the 2nd trimester? ✔Correct Answer-35-45%
S/S of Cardiac Disease ✔Correct Answer-- Dyspnea (limits ADLs)
- Progressive orthopnea/nocturnal dyspnea
- Chest pain with activity ischemia
- Swelling
- Decreased UO
