The nurse is calculating the estimated date of confinement (EDC) using Nagele's rule for a client whose last menstrual period started on February 13th. Which date is most accurate?
November 20
November 27
November 21
November 14
The Correct Answer is A
Choice A reason:
Nagele's rule for calculating the estimated date of confinement (EDC) involves subtracting 3 months from the first day of the last menstrual period and adding 7 days. For February 13th, subtracting 3 months gives us November 13th, and adding 7 days gives us November 20th. This is the most accurate calculation for the estimated date of confinement.
Choice B reason:
This choice is not accurate according to Nagele's rule. Adding 7 days to November 13th would give November 20th, not November 27th.
Choice reason:
This choice is not accurate according to Nagele's rule. Adding 7 days to November 13th would give November 20th, not November 21st.
Choice D reason:
This choice is not accurate according to Nagele's rule. Subtracting 3 months from February 13th would give November 13th, not November 14th.

Correct Answer is B
Explanation
Choice A reason: An antiemetic such as pyridoxine may be used to control vomiting in women with hyperemesis gravidarum, but it is not the initial treatment. The first priority is to restore fluid and electrolyte balance and prevent dehydration and hypovolemia.
Choice B reason: IV therapy is the initial treatment for women with hyperemesis gravidarum. It helps to correct fluid and electrolyte imbalances, prevent dehydration and hypovolemia, and restore normal blood pressure and urine output. IV fluids may also contain glucose, vitamins, and electrolytes to replenish losses.
Choice C reason: Enteral nutrition may be used to meet nutritional needs in women with hyperemesis gravidarum, but it is not the initial treatment. Enteral nutrition involves feeding through a tube inserted into the stomach or intestine. It may be considered if oral intake is not tolerated or adequate after IV therapy.
Choice D reason: Corticosteroids are not used to treat hyperemesis gravidarum. They are used to reduce inflammation in conditions such as asthma, rheumatoid arthritis, and allergic reactions. They have no effect on nausea and vomiting in pregnancy.
Correct Answer is D
Explanation
Choice A reason: Cramping is a common symptom of pregnancy, especially in the third trimester, due to the stretching of the ligaments and muscles that support the uterus. It is not a specific sign of abruptio placentae, which is the premature separation of the placenta from the uterine wall.
Choice B reason: Uterine activity is a normal phenomenon of pregnancy, as the uterus contracts and relaxes periodically. It is not a specific sign of abruptio placentae, which is associated with increased uterine tone and tenderness.
Choice C reason: Bleeding is a possible sign of both abruptio placentae and placenta previa, which is the implantation of the placenta over or near the cervical os. However, bleeding is more common and severe in placenta previa than in abruptio placentae, as the latter can have concealed hemorrhage.
Choice D reason: Intense abdominal pain is the most prevalent clinical manifestation of abruptio placentae, as the blood accumulates behind the placenta and causes pressure and irritation of the uterine nerves. It is a distinguishing sign from placenta previa, which is usually painless.
