A nurse is preparing to administer vitamin K 1mg IM to a newborn.
Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
Step 1: (1 mg ÷ 1 mg/0.5 mL) = 0.5 mL. Final answer: 0.5 mL.

Correct Answer is C
Explanation
Choice A rationale
Decreased arterial resistance is not associated with eclampsia. Eclampsia is characterized by increased arterial resistance due to hypertension and vascular changes during pregnancy.
Choice B rationale
Unexpected placental implantation is not a feature of eclampsia. Eclampsia is related to the development of seizures in the context of preeclampsia, which involves high blood pressure and organ damage.
Choice C rationale
Increased uterine spiral artery remodeling is associated with the pathophysiology of eclampsia. Poor remodeling leads to inadequate blood flow to the placenta, contributing to the development of hypertension and related complications.
Choice D rationale
Vasodilation is not typically associated with eclampsia. Instead, vasoconstriction and endothelial dysfunction are more common, leading to high blood pressure and potential organ damage.
Correct Answer is D
Explanation
Choice A rationale
An occult cord prolapse occurs when the umbilical cord is hidden but not necessarily within the vagina. It is often compressed alongside the fetus, causing a risk for decreased oxygenation.
Choice B rationale
An occult prolapsed cord is not characterized by being wrapped around the fetal neck; that condition is known as a nuchal cord.
Choice C rationale
A compound prolapsed cord does not involve the cord being felt through the cervix inside an intact amniotic sac. Instead, it involves the cord alongside the fetal presenting part.
Choice D rationale
An overt prolapsed cord occurs when the umbilical cord comes through the cervix ahead of the presenting part, posing significant risk due to potential cord compression and interruption of blood flow to the fetus.
