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 D
Explanation
Choice A rationale:
The instruction to "cover the cord with the diaper" is incorrect. It's essential to keep the umbilical cord stump dry and exposed to air to promote healing. Covering it with a diaper can trap moisture and increase the risk of infection.
Choice B rationale:
The recommendation to "wrap the cord in petroleum jelly gauze" is not appropriate. Applying petroleum jelly or other ointments to the cord stump is not recommended, as it can also trap moisture and create an environment for bacterial growth.
Choice C rationale:
The instruction to "bathe the newborn with a washcloth until the cord stump falls off" is not the best practice. It's advisable to give sponge baths and avoid submerging the cord stump until it has completely dried and fallen off. Using a washcloth may cause unnecessary friction and irritation.
Choice D rationale:
The advice to "wash the cord daily with mild soap and water" is the correct instruction. Cleaning the cord stump with mild soap and water and then gently patting it dry with a clean cloth is a standard practice for cord care. Keeping the area clean helps prevent infection and promotes healing.
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.
