A nurse is caring for a client who has an NG tube set to low intermittent suction. The nurse irrigates the NG tube twice with 30 mL of normal saline solution during his shift. At the end of the shift, the NG canister contains 475 mL. What amount of NG drainage should the nurse record? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason: This is incorrect because wearing spandex-type full-length pants can constrict the blood flow and increase the swelling in the feet. The nurse should advise the woman to wear loose-fitting clothes and comfortable shoes that do not squeeze or rub her feet.

Choice B Reason: This is correct because elevating the legs when sitting can improve venous return and reduce the swelling in the feet. The nurse should encourage the woman to elevate her legs above her heart level whenever possible and avoid crossing her legs or standing for long periods.

Choice C Reason: This is incorrect because limiting the intake of fluids can cause dehydration and worsen the swelling in the feet. The nurse should recommend the woman drink plenty of water and other healthy fluids to maintain hydration and flush out excess sodium and waste products from her body.

Choice D Reason: This is incorrect because eliminating salt from the diet can cause electrolyte imbalance and affect the fluid balance in the body. The nurse should advise the woman to consume salt in moderation and avoid processed foods that are high in sodium.

Choice A Reason: This is correct because this description accurately reflects one of the main functions of amniotic fluid, which is to act as a shock absorber and buffer against external forces or movements that could harm the fetus. Amniotic fluid also allows the fetus to move freely and develop its muscles and bones.

Choice B Reason: This is incorrect because this description is false. The amount of amniotic fluid changes throughout the pregnancy, depending on the stage of fetal development and other factors. The normal range of amniotic fluid volume is between 500 and 1000 mL at term. Too much or too little amniotic fluid can indicate a problem with the fetus or the placenta.

Choice C Reason: This is incorrect because this description is false. The fluid is not mostly protein, but mostly water (about 98%). The water comes from the mother's blood plasma and the fetal urine. The remaining 2% of amniotic fluid consists of various substances, such as electrolytes, hormones, enzymes, antibodies, and fetal cells. Amniotic fluid does not provide nourishment to the fetus, but rather protects it from infection and helps regulate its temperature.

Choice D Reason: This is incorrect because this description is false. Amniotic fluid does not act as a transport mechanism for oxygen and nutrients, but rather as a barrier that prevents them from reaching the fetus directly. Oxygen and nutrients are delivered to the fetus through the placenta and the umbilical cord, which are connected to the maternal blood circulation.
