After an emergency birth, the nurse encourages the woman to breastfeed her newborn.
The primary purpose of this activity is to:.

Choice A rationale:
Correction of acidosis is not the primary intervention for vaso-occlusive sickle cell crisis. The crisis primarily involves pain due to the obstruction of blood flow by sickled cells. Correcting acidosis is not a direct treatment for this condition.
Choice B rationale:
Adequate hydration is essential in managing vaso-occlusive sickle cell crisis. Proper hydration helps prevent dehydration, which can worsen the crisis and lead to complications. Hydration helps maintain blood flow and prevent further sickling of red blood cells.
Choice C rationale:
Pain management is a crucial intervention for a child with vaso-occlusive sickle cell crisis. Pain results from tissue ischemia caused by sickled red blood cells. Effective pain management, often with analgesics, helps improve the child's comfort and quality of life during the crisis.
Choice D rationale:
Administration of heparin is not indicated for vaso-occlusive sickle cell crisis. Heparin is an anticoagulant that prevents blood clot formation. In sickle cell crisis, the primary issue is the obstruction of blood flow by sickled cells, not the formation of clots. Administering heparin may not address the underlying problem and can lead to potential complications.
Choice E rationale:
Replacement of factor VIII is not relevant to vaso-occlusive sickle cell crisis. Factor VIII is a protein involved in blood clotting and is primarily used in the treatment of hemophilia, a different condition unrelated to sickle cell crisis.

The correct answer is choiceb. Fetal movement palpated by the nurse-midwife.

Choice A rationale:

A positive pregnancy test is considered a probable sign of pregnancy, not a positive sign. Probable signs are those that strongly suggest pregnancy but are not definitive.

Choice B rationale:

Fetal movement palpated by the nurse-midwife is a positive sign of pregnancy. Positive signs are those that provide definitive evidence of pregnancy, such as fetal heart tones heard by a Doppler device or ultrasound visualization of the fetus.

Choice C rationale:

Braxton Hicks contractions are considered a probable sign of pregnancy. These are irregular, painless contractions that can occur throughout pregnancy but do not confirm pregnancy definitively.

Choice D rationale:

Quickening, or the first feeling of fetal movement by the mother, is a presumptive sign of pregnancy. Presumptive signs are those that the woman experiences and reports, which may suggest pregnancy but are not conclusive.
