Anatomy and Physiology of Pregnancy Questions
Question 1 of 5
The decrease in systemic vascular resistance aids in decreasing which physiological measure?
Correct Answer: D
Rationale: The decrease in systemic vascular resistance leads to a decrease in blood pressure for the following reasons: 1. Vasodilation reduces resistance to blood flow in the blood vessels, lowering overall pressure. 2. As resistance decreases, the heart doesn't have to work as hard to pump blood, resulting in a decrease in blood pressure. 3. Lower resistance allows blood to flow more easily, reducing pressure on the arterial walls. The other choices are incorrect because: A: Decreasing systemic vascular resistance would typically increase cardiac output, not decrease it. B: Pulse rate is primarily affected by factors like sympathetic nervous system activity and not directly by changes in vascular resistance. C: Renal blood flow is more influenced by factors like renal artery pressure and hormonal regulation, rather than changes in systemic vascular resistance.
Question 2 of 5
After receiving information on the signs and symptoms of potential complications during pregnancy, the prenatal client knows to immediately report which of the following to her health care provider? Select all that apply.
Correct Answer: C
Rationale: The correct answer is C: Enlargement of breasts and tenderness. This is because backache, flank pain, burning on urination, abdominal cramping, and vaginal bleeding are not typically associated with potential complications during pregnancy. Enlargement of breasts and tenderness could indicate conditions like preeclampsia or ectopic pregnancy, which require immediate medical attention to prevent serious complications. The other choices do not directly relate to pregnancy complications and may not be urgent concerns. It's crucial for the prenatal client to report any unusual or concerning symptoms to her healthcare provider promptly to ensure the safety of both her and the baby.
Question 3 of 5
Now in her second trimester of pregnancy, the client, who was a marathon runner before nausea and overwhelming tiredness kept her from exercising regularly, is wondering whether she can run now. What is the nurse's best response?
Correct Answer: B
Rationale: The correct answer is B: "Your level of exercise will be somewhat modified by the changes occurring in your body." Rationale: 1. Pregnancy impacts a woman's body significantly, including changes in hormones, weight distribution, and center of gravity. 2. These changes can affect a woman's ability to engage in high-impact activities like running. 3. The nurse's response acknowledges the need for modification in exercise routine to accommodate these changes. 4. It promotes a balanced approach to exercise during pregnancy, considering both the benefits of physical activity and the safety of the mother and baby. Summary of Other Choices: A: "Certainly, if you feel up to it." - This response oversimplifies the situation and does not consider the specific physiological changes during pregnancy that may impact the woman's ability to run safely. C: "Your primary health care provider will need to give you permission." - While consulting a healthcare provider is important, this response does not address the specific concerns related to exercise during pregnancy.
Question 4 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 5 of 5
A woman who is primigravida is complaining of leg cramps. Which statement by the nurse best describes how to provide relief from this discomfort?
Correct Answer: B
Rationale: The correct answer is B: Dorsiflex the foot to relieve the cramping. Dorsiflexing the foot, which involves pulling the toes towards the shin, helps to stretch the calf muscle and alleviate cramping. This action targets the specific muscle group affected by leg cramps. A: Incorrect. Stretching by extending both legs and touching your toes may not directly target the calf muscle. C: Incorrect. Elevating the leg above the heart is more suitable for reducing swelling, not necessarily relieving leg cramps. D: Incorrect. Plantar flexing the foot (pointing toes away from the shin) may worsen the cramping as it contracts the calf muscle further.
