Anatomy and Physiology of Pregnancy Questions
Question 1 of 5
A client at 20 weeks gestation has just been examined during a prenatal visit. Which assessment should the nurse recognize as an abnormal finding and the need for further testing?
Correct Answer: A
Rationale: The correct answer is A. At 20 weeks gestation, the fundal height should correspond closely to the number of weeks pregnant (around 20 cm). A fundal height of 26 cm indicates potential fetal growth abnormalities or incorrect dating. Further testing, such as an ultrasound, is needed to assess fetal growth and well-being. Choice B (Pulse rate 15 bpm higher) is not typically concerning during pregnancy as pulse rate can increase due to physiological changes. Choice C (Blood pressure of 128/68) falls within the normal range for pregnancy. Choice D (Deep tendon reflexes +2) is a normal finding and not an indication for further testing.
Question 2 of 5
A client in her third trimester reports increased perineal pressure. Which is the clinical cause for this complaint?
Correct Answer: A
Rationale: The correct answer is A: Fundal height. In the third trimester, the growing uterus causes increased pressure on the pelvic organs, leading to perineal pressure. Fundal height measures the height of the uterus and correlates with gestational age, indicating the position and size of the fetus. As the uterus grows, fundal height increases, causing pressure on the perineal area. Urinary infection (B) can cause discomfort but would present with other symptoms like burning urination. Constipation (C) may cause discomfort but typically does not lead to increased perineal pressure. Hydramnios (D) refers to excess amniotic fluid, which can lead to abdominal distension but is not directly related to perineal pressure.
Question 3 of 5
A client at 10 weeks gestation is being seen by the nurse. The client reports that she has nausea and vomiting each morning. Which is the nurse's best response?
Correct Answer: B
Rationale: The correct answer is B: Eat crackers before you get out of bed. This is the best response because eating crackers before getting out of bed can help alleviate nausea and vomiting associated with morning sickness in early pregnancy. The crackers can help stabilize blood sugar levels and settle the stomach. Drinking a large glass of milk (choice A) may exacerbate nausea for some individuals. Eating dinner before 6:00 p.m. (choice C) is not directly related to morning sickness. Eating small meals during the day (choice D) is generally a good strategy, but specifically eating crackers before getting out of bed is more effective for morning sickness.
Question 4 of 5
The woman who is primigravida is in the clinic for her first prenatal visit. She states that she has experienced dizziness when she gets out of bed and sometimes when she stands up from a sitting position. What is the reason for this?
Correct Answer: B
Rationale: The correct answer is B: She is standing up too quickly and must be careful to avoid injury. When a person stands up quickly, blood pools in the lower extremities, causing a momentary drop in blood pressure. This sudden drop can lead to dizziness or lightheadedness. This phenomenon is known as orthostatic hypotension. It is common during pregnancy due to the hormonal and physiological changes that affect blood pressure regulation. Explanation for why other choices are incorrect: A: She is experiencing hypoglycemia from being diabetic - There is no information provided in the scenario to suggest that the woman is diabetic or experiencing low blood sugar levels. C: She needs to drink more fluids to prevent orthostatic hypotension and it will clear up soon - While staying hydrated is important, simply drinking more fluids may not address the underlying issue of orthostatic hypotension caused by rapid changes in position. D: She is not getting enough exercise, so circulation to the
Question 5 of 5
A woman at 10 weeks of gestation who is seen in the prenatal clinic with presumptive signs and symptoms of pregnancy likely will have:
Correct Answer: A
Rationale: The correct answer is A: amenorrhea. At 10 weeks of gestation, a woman should have missed at least two menstrual periods, indicating amenorrhea. This is a presumptive sign of pregnancy as it is a common early pregnancy symptom. Positive pregnancy test (B) confirms pregnancy but is not specific to 10 weeks. Chadwick's sign (C) is a bluish discoloration of the cervix and vagina, typically seen around 6-8 weeks, not specifically at 10 weeks. Hegar's sign (D) is softening of the lower uterine segment, usually felt around 6-12 weeks, not specifically at 10 weeks.
