The nurse is educating a class of expectant parents about fetal development. What is considered fetal age of viability?

Answer and Explanation

The Correct Answer is C

A. At 8 weeks, the embryo is transitioning into the fetal stage of development and is not viable outside the womb. Organs are still in the early stages of formation.

B. While some sources may consider 24 weeks the age of "reasonable viability" with intensive medical support, many medical guidelines recognize viability beginning as early as 20 weeks under optimal conditions.

C. The age of 20 weeks is often cited as the lower threshold of fetal viability due to improved neonatal care, although survival rates improve significantly after this point.

D. At 14 weeks, the fetus is in the second trimester, but it is far too underdeveloped for survival outside the womb.

Correct Answer is A

Explanation

A. Supine hypotension syndrome occurs when the gravid uterus compresses the inferior vena cava when the woman is lying flat on her back, leading to decreased venous return, lowered cardiac output, and a drop in blood pressure. This can cause dizziness, lightheadedness, and sometimes fainting. It is more common in the later stages of pregnancy, such as at 38 weeks.

B. Pregnancy-induced hypotension refers to a decrease in blood pressure due to pregnancy, but it typically does not occur specifically when lying on the back, and is not the main cause of dizziness when positioned in that way.

C. Anxiety can cause dizziness, but it is not the most likely cause of dizziness related to lying flat on the back, especially in late pregnancy.

D. Hypoglycemia can cause dizziness, but it is not typically triggered by a change in position like lying on the back, making it less likely in this scenario.

A. "Don't worry, I will stay in there with you for the exam." B. "A pelvic exam is required if you want birth control pills.” C. "Tell me more about your concerns.” D. "All you need to do is relax during the exam.”

Correct Answer is C

Explanation

A. Offering to stay with the client may be supportive, but it does not directly address the client’s expressed feelings or concerns, which is the priority in therapeutic communication.

B. Telling the client that the exam is necessary for birth control may seem dismissive and does not validate or explore her anxiety.

C. Encouraging the client to share more about her concerns is an appropriate therapeutic response. It allows the nurse to understand the client’s feelings, provide reassurance, and educate her about the procedure.

D. Advising the client to relax may come across as minimizing her feelings and does not provide an opportunity for the client to express her anxiety.
