A nurse in a prenatal clinic is caring for a client who is pregnant and asks the nurse for her estimated date of birth (EDB). The client's last menstrual period began on October 17. What is the client's EDB? (State the date in MMDD.
For example, October 17 is 1017)
Step 1 is: October 17 + 7 days = October 24.
Step 2 is: October 24 - 3 months = July 24.
Step 3 is: July 24 + 1 year = July 24. Answer: July 24 (0724)
The Correct Answer is A
Step 1 is: October 17 + 7 days = October 24.
Step 2 is: October 24 - 3 months = July 24.
Step 3 is: July 24 + 1 year = July 24. Answer: July 24 (0724)

Correct Answer is C
Explanation
Choice A rationale
A reaction from an epidural can cause side effects such as hypotension and shivering, but it is not related to tachysystole.
Choice B rationale
When the fetus's heart rate drops below baseline, it is termed bradycardia, not tachysystole. This condition can occur due to various reasons, including cord prolapse or placental insufficiency.
Choice C rationale
Tachysystole is defined as more than five contractions in 10 minutes. This condition can lead to reduced blood flow to the fetus, resulting in fetal distress.
Choice D rationale
Pitocin is a medication used to induce labor and can cause tachysystole, but the administration of Pitocin itself is not the definition of tachysystole. It's the increased frequency of contractions that defines the condition.
Correct Answer is C
Explanation
Choice A rationale
The placenta does not provide thermoregulation; that function is managed by maternal thermoregulation and the amniotic fluid which insulates the fetus.
Choice B rationale
Amniotic fluid cushions the fetus from maternal movements, not the placenta. The placenta's role is more focused on nutrient and waste exchange.
Choice C rationale
The placenta facilitates metabolic functions and gas exchange, supplying oxygen and nutrients to the fetus while removing carbon dioxide and waste products, ensuring fetal development.
Choice D rationale
The placenta doesn't provide a sterile environment. This is accomplished by the amniotic sac and amniotic fluid. The placenta connects the fetus to maternal blood supply, ensuring necessary exchanges for fetal growth.
