The nurse explains that blood volume increases during pregnancy that will offset the loss. Which of the following is the correct percentage of increased blood volume during pregnancy that the nurse should explain to the client?
25%-35%.
10%-20%.
60%-70%.

The Correct Answer is D
Choice A rationale
A 25%-35% increase in blood volume is lower than the actual increase observed during pregnancy. This choice is incorrect.
Choice B rationale
A 10%-20% increase in blood volume is significantly lower than the actual increase observed during pregnancy. This choice is incorrect.
Choice C rationale
A 60%-70% increase in blood volume is higher than the actual increase observed during pregnancy. This choice is incorrect.

Correct Answer is C
Explanation
Choice A rationale
The placenta does not cushion the fetus from maternal movement. Instead, the amniotic fluid within the amniotic sac provides cushioning and protection to the fetus from external forces and maternal movements.
Choice B rationale
The placenta does not provide thermoregulation. Thermoregulation is primarily managed by the mother’s body. The placenta’s main functions are related to nutrient and gas exchange, hormone production, and waste removal.
Choice C rationale
The placenta is responsible for metabolic and gas exchange. It provides oxygen and nutrients to the fetus while removing waste products from the fetal blood. This exchange occurs through the placental barrier, which separates maternal and fetal blood.
Choice D rationale
The placenta does not provide a sterile environment. The amniotic sac and its fluid help maintain a sterile environment for the fetus. The placenta’s role is more focused on nutrient and gas exchange, hormone production, and waste removal.
Correct Answer is ["C","E","G"]
Explanation
Choice C rationale
Lower abdominal cramping during early pregnancy can be a sign of various conditions, including normal uterine growth, but it can also indicate potential complications such as an ectopic pregnancy or miscarriage. It is crucial to report this symptom to the provider to rule out any serious issues and ensure the safety of both the mother and the fetus.
Choice E rationale
Vaginal spotting during early pregnancy can be a sign of implantation bleeding, which is usually harmless. However, it can also indicate more serious conditions such as a threatened miscarriage or an ectopic pregnancy. Reporting this symptom to the provider is essential for further evaluation and appropriate management.
Choice G rationale
Dysuria, or painful urination, can be a sign of a urinary tract infection (UTI), which is common during pregnancy due to hormonal changes and the growing uterus pressing on the bladder. UTIs can lead to complications if left untreated, so it is important to report this symptom to the provider for prompt diagnosis and treatment.
