Calculate the gravity rate for gentamycin 100 mg/100ml with secondary tubing (20gtts/mL) over 60 minutes.

A) Goodell’s sign:
Goodell's sign refers to the softening of the cervix that occurs early in pregnancy, typically around 4–6 weeks. It is a probable sign of pregnancy due to increased vascularity and hormonal changes. However, it does not describe the movement of the fetus or the sensation felt by the provider when pressure is applied to the cervix.

B) Lightening:
Lightening refers to the sensation of the fetus dropping or descending into the pelvic cavity, which typically happens in the later stages of pregnancy (around 36 weeks or later). It is not related to the fetal movement felt by the provider through upward pressure on the cervix, but rather to the physical repositioning of the fetus as it prepares for labor.

C) Ballottement:
Ballottement is the correct term for the movement of the fetus that can be felt by the provider when upward pressure is applied to the cervix. This technique involves a gentle tapping or pushing on the cervix, causing the fetus to rise and then "bounce" back. This is a probable sign of pregnancy, typically noticeable between 16 and 18 weeks gestation.

D) Chadwick's sign:
Chadwick’s sign refers to the bluish discoloration of the cervix, vagina, and vulva due to increased blood flow and is often an early sign of pregnancy. It does not relate to the movement of the fetus felt by the provider, but rather to changes in the color of the genital tissues.

A) Decrease the heart rate of the fetus:
Lying on the left side can sometimes help improve fetal oxygenation, especially if there is a concern about reduced blood flow from compression of the inferior vena cava, which can occur when the mother lies on her back. However, the primary rationale for this position is to prevent supine hypotension, not specifically to decrease fetal heart rate. In fact, side-lying can promote better oxygen exchange, which can indirectly benefit the fetal heart rate.

B) Aid the women while she pushes:
While a left-side lying position may offer comfort during labor and can help with uterine positioning, it is not specifically intended to aid in the pushing phase. Positions such as squatting or hands-and-knees are generally more helpful during the pushing phase because they can facilitate effective pushing and help the baby descend into the birth canal. The left-side position is more about circulation and preventing hypotension.

C) Prevent supine hypertension:
Supine hypotension occurs when the pregnant woman lies flat on her back, which can compress the inferior vena cava and reduce blood return to the heart. This leads to a drop in blood pressure and can compromise both maternal and fetal circulation. The left-side position is recommended because it helps to prevent this compression and allows optimal blood flow to both the mother and fetus, improving oxygenation and circulation.

D) Prevent the client from falling out of bed:
While lying on the left side may make the woman feel more stable, the primary reason for this position is to prevent supine hypotension, not to prevent her from falling out of bed. The nurse would ensure safety by using appropriate bed rails and monitoring, but the primary concern is supporting optimal circulation, not preventing falls.
