A nurse is preparing to administer vitamin K 1 mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose?
Choice A: 0.25 mL
Choice B: 0.5 mL
Choice C: 0.75 mL
Choice D: 1 mL
The Correct Answer is B
Choice A rationale:
0.25 mL - The nurse should not administer 0.25 mL because the available concentration of vitamin K injection is 1 mg/0.5 mL. To achieve the prescribed dose of 1 mg, administering only 0.25 mL would be insufficient.
Choice B rationale:
0.5 mL - This is the correct choice. The nurse should administer 0.5 mL of the vitamin K injection to deliver 1 mg of vitamin K, as the concentration of the injection is 1 mg/0.5 mL. By giving the full 0.5 mL, the newborn will receive the appropriate 1 mg dose.
Choice C rationale:
0.75 mL - Administering 0.75 mL would be excessive for the prescribed 1 mg dose of vitamin K. It is unnecessary to give a higher volume than required, as it could lead to potential adverse effects or wastage.
Choice D rationale:
1 mL - Similarly, administering the entire 1 mL of the vitamin K injection would result in doubling the prescribed dose, leading to potential overdose and adverse reactions. The nurse should avoid administering more than the necessary 0.5 mL.

Correct Answer is B
Explanation
Choice B rationale:
The correct answer is Choice B, which is "Newborn hypoglycemia.”. Newborn hypoglycemia is a potential complication associated with maternal gestational diabetes. When a pregnant woman has gestational diabetes, her blood glucose levels can be elevated, leading to increased insulin production in the fetus. After birth, the baby's insulin production continues at a high level, which can result in a rapid drop in blood glucose levels, causing hypoglycemia. This condition can be serious and requires close monitoring and timely intervention to prevent complications in the newborn.
Choice A rationale :
Placenta previa is not a complication associated with maternal gestational diabetes. Placenta previa occurs when the placenta partially or completely covers the cervix, which can lead to bleeding during pregnancy and delivery. However, this condition is not directly related to gestational diabetes, and there is no physiological rationale connecting the two.
Choice C rationale
Small for gestational age (SGA) newborn is not a direct complication of maternal gestational diabetes. SGA refers to babies who are smaller in size than expected for their gestational age. While poorly controlled diabetes during pregnancy can lead to large babies (macrosomia), it is not typically associated with small babies.
Choice D rationale
Oligohydramnios, which is a condition characterized by low levels of amniotic fluid, is not a common complication associated with maternal gestational diabetes. Oligohydramnios can be caused by various factors, but it is not specifically linked to gestational diabetes.
Correct Answer is D
Explanation
The correct answer is choice D. Uterine contraction lasting 2 min.
Choice A rationale:
Early decelerations in the FHR are usually not a concern during the second stage of labor. They are a normal physiological response to the compression of the fetal head during contractions and are generally considered benign.
Choice B rationale:
Pelvic pressure with contractions is a normal finding during the second stage of labor as the baby descends into the pelvis. It does not typically require reporting to the provider unless it is associated with other concerning symptoms.
Choice C rationale:
A bloody show from the vagina is a common and expected finding during the second stage of labor. It indicates that the cervix is dilating and effacing, which is a normal part of the labor process.
Choice D rationale:
A uterine contraction lasting 2 minutes is abnormal and could indicate uterine tachysystole, which can lead to fetal distress due to reduced uterine blood flow and oxygen to the fetus. This finding should be reported to the provider immediately.
