Correct Answer is ["415"]
Explanation
To calculate the amount of NG drainage, the nurse should subtract the amount of irrigation fluid from the amount of fluid in the NG canister. The irrigation fluid is not part of the drainage, but rather a way to keep the NG tube patent and prevent clogging.
The amount of irrigation fluid is 30 mL x 2 = 60 mL.
The amount of fluid in the NG canister is 475 mL.
Therefore, the amount of NG drainage is 475 mL - 60 mL = 415 mL.
The answer should be rounded to the nearest whole number and use a leading zero if it applies. Do not use a trailing zero.
Therefore, the final answer is 415 mL.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because administering Rho(D) immune globulin 24 hours before delivery is too early and may not provide adequate protection for the fetus. Administering it 24 hours after delivery is too late and may not prevent the mother from developing antibodies against the fetal Rh-positive blood cells.
Choice B Reason: This is incorrect because administering Rho(D) immune globulin in the first trimester is unnecessary and may not be effective, as the risk of Rh isoimmunization is very low before 28 weeks of gestation. Administering it within 2 hours of delivery is appropriate, but not sufficient, as it should be repeated within 72 hours after delivery.
Choice C Reason: This is correct because administering Rho(D) immune globulin at 28 weeks gestation and again within 72 hours after delivery is the recommended schedule for preventing Rh isoimmunization in Rh-negative pregnant women who have Rh-positive partners. This regimen can prevent up to 99% of cases of Rh isoimmunization by blocking the maternal immune response to the fetal Rh-positive blood cells.
Choice D Reason: This is incorrect because administering Rho(D) immune globulin at 32 weeks gestation is too late and may not prevent Rh isoimmunization if there has been any fetal-maternal hemorrhage before that time. Administering it immediately before discharge is also too late and may not prevent the mother from developing antibodies against the fetal Rh-positive blood cells.
