The nurse is going to administer a dose of Vitamin K (Aquamephyton) 0.5mg IM to a newborn. Available: Vitamin K 1 mg/1ml. How many mLs would the nurse administer? (Please answer numerically only)
The Correct Answer is ["0.5"]
Given:
Desired dose: Vitamin K 0.5 mg IM
Available concentration: Vitamin K 1 mg/1 mL
To find:
Volume to administer (in mL)
Step 1: Set up the proportion
We can use the following proportion to solve the problem:
(Desired dose) / (Available concentration) = Volume to administer
Step 2: Substitute the values
Plugging in the given values, we get:
(0.5 mg) / (1 mg/1 mL) = Volume to administer
Step 3: Simplify
To simplify, we can invert the denominator and multiply:
(0.5 mg) x (1 mL / 1 mg) = Volume to administer
The "mg" units cancel out, leaving us with:
(0.5 x 1 mL) / 1 = Volume to administer
Step 4: Calculate
Performing the multiplication and division, we get:
0.5 mL / 1 = Volume to administer
0.5 mL Volume to administer

Correct Answer is B
Explanation
A) Soft, nontender, colostrum is present:
In the early postpartum period, specifically on day 1, the woman is still in the process of transitioning from producing colostrum (a thick, yellowish fluid rich in antibodies) to mature breast milk. The colostrum may be present, but the breasts are typically not soft and nontender. Instead, they are more likely to be swollen and tender as the milk production ramps up. Therefore, this is not the typical finding on day 1 postpartum.
B) Swollen, warm, and tender upon palpation:
This is the expected finding on day 1 postpartum, especially for a primiparous woman. After childbirth, the breasts begin the transition from producing colostrum to mature breast milk. The increased blood flow and milk production cause the breasts to become swollen, warm, and tender to the touch. This condition is often referred to as engorgement, which is common within the first few days after delivery, particularly in breastfeeding mothers. Engorgement usually peaks around day 3 but may begin to occur slightly earlier, as the body adjusts to milk production.
C) Leakage of milk at let-down:
This finding is more typical of a woman who is further along in the postpartum period, usually after her milk has transitioned from colostrum to mature milk. Milk let-down and the associated leakage typically occur later, often after a few days (around day 3 or later). On day 1, the milk supply is still establishing itself, and leakage is less common.
D) A few blisters and bruises on each areola:
Blisters and bruises on the areola could indicate improper latch or trauma from breastfeeding. This is not a typical or expected finding in a woman who is only 1 day postpartum. If this occurs, the nurse should assess the infant’s latch and the breastfeeding technique to prevent further complications. Such findings should be addressed promptly, but they are not considered normal on day 1.
Correct Answer is ["A","C","D"]
Explanation
A) Clear fluids from airway:
Immediately clearing the infant's airway is one of the first steps in stabilizing the newborn after birth. This ensures the infant can breathe freely, reducing the risk of aspiration or airway obstruction. Suctioning the mouth and nose with a bulb syringe or suction catheter is the usual practice, especially if there are visible fluids or secretions. This intervention is critical for ensuring the infant's respiratory function.
B) Immediately assess and bathe baby:
While assessing the newborn is vital, it is not the immediate priority. The first step in stabilization is ensuring the newborn’s airway is clear, followed by efforts to prevent heat loss. Bathing should be delayed until after the baby is stable, and drying the baby thoroughly should be done as the first action to prevent hypothermia.
C) Dry infant thoroughly:
Drying the newborn thoroughly after birth is essential for preventing heat loss. Wet skin can quickly lead to hypothermia, and drying helps maintain the infant's body temperature. This intervention is vital for stabilizing the newborn and ensuring thermoregulation in the first moments of life.
D) Place baby skin to skin:
Skin-to-skin contact is a fundamental practice immediately after birth. It promotes bonding, helps regulate the infant's temperature, supports successful breastfeeding initiation, and stabilizes vital signs like heart rate and blood sugar levels. The mother’s body heat helps the baby maintain a normal temperature, which is especially important right after birth.
E) Give erythromycin ointment in baby’s eyes:
While applying erythromycin ointment to the baby’s eyes is a standard practice to prevent neonatal conjunctivitis (especially from gonorrhea or chlamydia), it is not a priority for immediate stabilization. This step is typically performed later, after the newborn is stable, and thermoregulation is addressed. The primary focus should be on airway clearance, drying, and promoting skin-to-skin contact first.
