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.).

Choice A rationale:

Copious vaginal bleeding Rationale: Copious vaginal bleeding, especially if it's heavy and associated with pain, can be a sign of a miscarriage or other significant complications during pregnancy. While some bleeding can be normal in early pregnancy (implantation bleeding), copious bleeding is not expected and should prompt immediate medical attention. However, it is not a typical finding for an ectopic pregnancy.

Choice B rationale:

Pelvic pain Rationale: Pelvic pain is a concerning symptom in a client with a possible ectopic pregnancy. Ectopic pregnancies occur when the fertilized egg implants outside the uterus, often in the fallopian tube. As the embryo grows, it can cause the tube to rupture, leading to severe abdominal pain and internal bleeding. Pelvic pain is a hallmark symptom of an ectopic pregnancy and should be reported to the provider immediately.

Choice C rationale:

Uterine enlargement greater than expected for gestational age Rationale: Uterine enlargement is expected during pregnancy as the uterus accommodates the growing fetus. However, in the case of an ectopic pregnancy, the fertilized egg implants outside the uterus, typically in the fallopian tube. Therefore, uterine enlargement greater than expected for gestational age would not be a typical finding. This choice is not correct for an ectopic pregnancy.

Choice D rationale:

Severe nausea and vomiting Rationale: Severe nausea and vomiting can be associated with pregnancy-related conditions like hyperemesis gravidarum, but it is not a typical finding in ectopic pregnancies. Ectopic pregnancies are more likely to present with pelvic pain and may progress to severe abdominal pain if the fallopian tube ruptures. .

Choice A rationale:

The purpose of administering vitamin K to a newborn is to prevent bleeding. Vitamin K plays a crucial role in blood clotting. Newborns often have lower levels of vitamin K, which can make them more susceptible to bleeding disorders, such as hemorrhagic disease of the newborn (HDN). HDN can lead to serious bleeding complications, including intracranial hemorrhage, which can be life-threatening.

Choice B rationale:

Hyperbilirubinemia is not the primary purpose of administering vitamin K. While vitamin K can indirectly help in preventing jaundice (hyperbilirubinemia) by reducing the risk of bleeding that may lead to hemolysis, it is not the primary aim of vitamin K administration.

Choice C rationale:

Potassium deficiency (hypokalemia) is not a primary concern related to vitamin K administration. Vitamin K is specifically administered to prevent bleeding disorders and not to address potassium levels.

Choice D rationale:

Infection is not related to the administration of vitamin K. Vitamin K is not used to prevent or treat infections in newborns; its primary role is in blood clotting.
