A patient is being prepared for an amniocentesis. The patient is a G2P1 and is 34 weeks gestation suffering from pre eclampsia. The patient asks what the purpose of this amniocentesis is. The best response from the nurse would be:
To identify abnormal fetal cells.
To detect metabolic disorders.
To determine fetal lung maturity.
To identify the sex of the fetus.
The Correct Answer is C
A. To identify abnormal fetal cells: This is typically the purpose of amniocentesis earlier in pregnancy to check for genetic disorders, not at 34 weeks.
B. To detect metabolic disorders: Metabolic disorders are usually identified through newborn screening after birth rather than through late pregnancy amniocentesis.
C. To determine fetal lung maturity: At 34 weeks gestation, determining fetal lung maturity is critical, especially in cases of preeclampsia, as early delivery might be necessary.
D. To identify the sex of the fetus: The sex of the fetus is usually determined earlier in pregnancy if necessary, not at 34 weeks, and it is not the primary purpose in this context.

Correct Answer is B, E, D, F, A, C
Explanation
Meiosis is the process of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and egg). This is the first step in the process of reproduction.
Fertilization occurs when a sperm cell unites with an egg cell to form a zygote. This marks the beginning of the formation of a new organism.
The zygote is the single-cell result of fertilization. It will undergo several mitotic divisions to form a blastocyst.
The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass that will eventually develop into the embryo.
Nidation, or implantation, occurs when the blastocyst attaches to the uterine wall.
After implantation, the endometrium is called the decidua, which provides a nourishing environment for the developing embryo.
Correct Answer is B
Explanation
A. Calcium gluconate is used for hypocalcemia, not for treating hypotension.
B. Ephedrine is a vasopressor used to treat hypotension, which can occur as a side effect of epidural anesthesia by helping to increase blood pressure.
C. Apresoline is an antihypertensive and would not be appropriate for treating hypotension.
D. Nifedipine is a calcium channel blocker used for hypertension, not for treating hypotension related to epidural anesthesia.
