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.).
0.5
1.0
2.0
0.6
The Correct Answer is A
Choice A rationale:
To calculate the amount of vitamin K (1 mg) to administer, you need to use the given concentration (1 mg/0.5 mL). This means that 1 mg is present in every 0.5 mL of the solution. To determine how many milliliters (mL) you should administer to get 1 mg, you can set up a proportion: 1 mg / X mL = 1 mg / 0.5 mL Cross-multiply and solve for X: X = (1 mg * 0.5 mL) / 1 mg X = 0.5 mL Therefore, the nurse should administer 0.5 mL, which can be rounded to 2.0 mL to the nearest tenth of a milliliter. Now, let's move on to the next question.

Correct Answer is C
Explanation
Answer and explanation
A nurse is reinforcing teaching with a newly licensed nurse about the complications associated with maternal gestational diabetes. Which of the following complications should the nurse include? The correct answer is choice C: Newborn hypoglycemia.
Choice A rationale:
Small for gestational age (SGA) newborns are not typically associated with maternal gestational diabetes. Instead, maternal diabetes (both pre-gestational and gestational) is more commonly linked to larger-than-average babies, known as macrosomia or LGA (large for gestational age).
Choice B rationale:
Oligohydramnios is a condition characterized by a decreased volume of amniotic fluid, which can have various causes. While maternal diabetes can contribute to certain complications, it is not a direct cause of oligohydramnios.
Choice C rationale:
Newborn hypoglycemia is a significant complication associated with maternal gestational diabetes. When a pregnant woman has diabetes, her baby may experience high blood sugar levels in the womb, leading to increased insulin production. After birth, the baby's insulin production continues, causing a drop in blood sugar levels, which can result in hypoglycemia. Therefore, this is a complication that should be emphasized in teaching.
Choice D rationale:
Placenta previa is not directly related to maternal gestational diabetes. It is a condition in which the placenta partially or completely covers the cervix, leading to bleeding during pregnancy. It is a separate complication from gestational diabetes and should not be included in teaching about the complications of maternal diabetes.
Correct Answer is A
Explanation
Choice A rationale:
The rooting reflex is the newborn's natural response to touch around their mouth, particularly the cheek. When the cheek is touched, the infant will turn their head in that direction and open their mouth, initiating the sucking reflex. This reflex helps the newborn find the breast or bottle for feeding.
Choice B rationale:
The Moro reflex is not associated with the initiation of sucking. The Moro reflex is a startle reflex that involves extending and retracting the arms and legs when a newborn feels a sudden loss of support or experiences a loud noise.
Choice C rationale:
The stepping reflex is not related to the initiation of sucking. The stepping reflex is an automatic response that occurs when you hold a newborn upright with their feet touching a surface, causing them to make stepping movements.
Choice D rationale:
The Babinski reflex involves the extension and fanning out of the toes when the sole of the foot is stroked. It is not associated with the initiation of sucking.
