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","C"]
Explanation
Choice A rationale:
The nurse does not need to report the blood pressure finding. While blood pressure is an essential vital sign to monitor during pregnancy, the scenario does not indicate any abnormalities or concerning values in the client's blood pressure. Therefore, there is no immediate cause for reporting this finding.
Choice B rationale:
The nurse should report cerebral manifestations to the provider. The client's complaint of a more severe headache, rated at 5 on a 0 to 10 pain scale, along with feeling dizzy when getting up from the examination table, may indicate potential neurological symptoms. These could be signs of conditions like preeclampsia, which is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, including the brain.
Choice C rationale:
The nurse should also report fetal heart rate findings to the provider. The client reports occasional contractions and positive fetal movement, but there is no mention of fetal heart rate in the nurse's notes. Monitoring the fetal heart rate is crucial during prenatal care, as changes in fetal heart rate could indicate fetal distress or other complications.
Choice D rationale:
The nurse does not need to report respiratory rate findings. There is no indication in the nurse's notes of any respiratory issues or complaints from the client, making this finding less relevant to the current situation.
Choice E rationale:
The nurse does not need to report deep tendon reflexes in this context. Deep tendon reflexes are not typically a priority assessment during routine prenatal care unless there are specific concerns or indications of neurological issues.
Choice F rationale:
The nurse does not need to report gastrointestinal assessment findings based on the information provided in the scenario. While the client reports "heartburn,”. there are no other gastrointestinal symptoms or indications of acute gastrointestinal issues requiring immediate reporting.
Correct Answer is B
Explanation
Choice A rationale:
Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.
Choice B rationale:
nature.
Choice C rationale:
Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.
Choice D rationale:
Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which c
