A nurse is preparing to administer penicillin G benzathine 1.2 million units IM now. The amount available is penicillin G benzathine 600,000 units/mL. How many mL should the nurse administer?
(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 it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 18.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.

Choice A Reason: This is correct because this response provides realistic and supportive advice for a woman who wants to have a baby with lupus. Lupus is an autoimmune disease that causes inflammation and damage to various organs and tissues. Lupus can affect fertility and pregnancy outcomes, such as increasing the risk of miscarriage, preterm delivery, preeclampsia, or neonatal lupus. Therefore, it is important for the woman to have her lupus under control before conceiving and to consult with her doctor about her treatment plan and prenatal care.

Choice B Reason: This is incorrect because this response is discouraging and insensitive for the woman who wants to have a baby with lupus. Lupus does not necessarily prevent a woman from having a healthy pregnancy and a healthy baby, as long as she follows her doctor's recommendations and monitors her condition closely. The nurse should respect the woman's reproductive choices and provide information and support.

Choice C Reason: This is incorrect because this response is inaccurate and misleading for the woman who wants to have a baby with lupus. Lupus can have various effects on pregnancy, such as causing flares or complications that can affect both the mother and the baby. The nurse should educate the woman about the possible risks and benefits of pregnancy with lupus and help her prepare for any challenges.

Choice D Reason: This is incorrect because this response is vague and alarming for the woman who wants to have a baby with lupus. Lupus treatment may or may not change during pregnancy, depending on the type and severity of lupus, the medications used, and the stage of pregnancy. The nurse should explain the rationale and safety of any medication changes and address any concerns or questions that the woman may have.
