Question 3 of 5
During vital sign assessment of a pregnant patient in her third trimester, the patient complains of feeling faint, dizzy, and agitated. Which nursing intervention is most appropriate?
Correct Answer: D
Rationale: The correct answer is D: Have the patient turn to her left side and recheck her blood pressure in 5 minutes. This intervention is most appropriate because the patient is experiencing symptoms of potential hypotension, common in pregnant women due to changes in blood volume and hormonal levels. Turning the patient to her left side helps improve blood flow to the heart and can alleviate symptoms. Rechecking the blood pressure in 5 minutes allows for monitoring of any changes. Choice A is incorrect as it does not provide a specific intervention. Choice B is incorrect as having the patient stand up may worsen symptoms. Choice C is incorrect as holding the arm in a dependent position may not effectively address the underlying issue of hypotension.
Question 4 of 5
What is the physiologic reason for vascular volume increasing by 40% to 60% during pregnancy?
Correct Answer: C
Rationale: The correct answer is C: Provides adequate perfusion of the placenta. During pregnancy, the increased vascular volume ensures sufficient blood flow to the placenta, supplying oxygen and nutrients to the developing fetus. This is crucial for fetal growth and development. The other choices are incorrect because: A: Preventing maternal and fetal dehydration is not the main reason for the significant increase in vascular volume during pregnancy. B: Eliminating metabolic wastes of the mother does not require such a substantial increase in vascular volume. D: Compensating for decreased renal plasma flow is not the primary physiologic reason for the vascular volume expansion during pregnancy.
Question 5 of 5
Which finding is a positive sign of pregnancy?
Correct Answer: B
Rationale: The correct answer is B: Breast changes. During pregnancy, hormonal changes cause breast enlargement, tenderness, and darkening of the areolas. This is considered a positive sign of pregnancy because it is a direct physiological response to the hormonal changes associated with pregnancy. Amenorrhea (choice A) is a common early sign of pregnancy but can also be due to other factors. Fetal movement (choice C) and visualization of fetus by ultrasound (choice D) are considered presumptive and probable signs of pregnancy, respectively, but not definitive positive signs like breast changes.
