The nurse administers vitamin K to the newborn for what reason?

Bacteria that synthesize vitamin K are not present in the newborn's intestinal tract.

Vitamin K prevents the synthesis of prothrombin in the liver and must be given by injection.

The supply of vitamin K is inadequate for at least 12 months, and the newborn musti supplemented throughout infancy.

Most mothers have a diet deficient in vitamin K, which results in the infant being deficient.

Answer and Explanation

The Correct Answer is A

A) Bacteria that synthesize vitamin K are not present in the newborn's intestinal tract:
Newborns are born with a sterile gastrointestinal tract, meaning they do not yet have the intestinal bacteria necessary to synthesize vitamin K. Vitamin K is essential for the activation of clotting factors, and without sufficient vitamin K, newborns are at risk for bleeding disorders, particularly a condition known as vitamin K deficiency bleeding (VKDB). Administering vitamin K by injection shortly after birth ensures the baby has adequate levels to prevent bleeding.
B) Vitamin K prevents the synthesis of prothrombin in the liver and must be given by injection:
This statement is incorrect. Vitamin K does not prevent the synthesis of prothrombin; rather, it is essential for the liver to synthesize clotting factors, including prothrombin. The injection of vitamin K in newborns is necessary to provide adequate levels of vitamin K to support proper blood clotting, as newborns cannot produce enough on their own at birth due to the absence of gut bacteria that normally produce it.

C) The supply of vitamin K is inadequate for at least 12 months, and the newborn must be supplemented throughout infancy:
While it is true that newborns have a limited supply of vitamin K at birth, this deficiency is typically addressed with a single injection given shortly after birth. Supplementing vitamin K throughout infancy is generally not required, as the infant's gastrointestinal tract will start to develop the necessary bacteria to synthesize vitamin K within the first few weeks to months of life. The first dose of vitamin K prevents bleeding disorders, and in most cases, additional supplementation is not necessary.

D) Most mothers have a diet deficient in vitamin K, which results in the infant being deficient:
While maternal diet does play a role in the newborn's initial vitamin K levels, it is not the primary reason for the deficiency. Vitamin K deficiency in newborns is primarily due to the lack of gut bacteria necessary to produce it, rather than maternal diet. The practice of administering vitamin K to all newborns ensures that they receive adequate levels to prevent bleeding, regardless of maternal dietary intake.

Correct Answer is A

Explanation

A. Excessive uterine bleeding:
Bladder distention can displace the uterus to the right and elevate it above the umbilicus, interfering with uterine contraction. This displacement prevents the uterus from contracting effectively, which can lead to excessive uterine bleeding, a serious complication. When the uterus does not contract properly, it may not effectively compress the blood vessels, increasing the risk of hemorrhage. Immediate attention to bladder distention is crucial to prevent this potentially life-threatening issue.

B. Urinary tract infection:
While urinary tract infections (UTIs) can occur in the postpartum period, especially if the bladder is not emptied completely, they are not the most immediate or serious consequence of bladder distention. The priority is to address the distended bladder to prevent complications like excessive bleeding. A UTI would be a concern later, but it would not be the most acute risk following delivery.

C. Ruptured bladder:
A ruptured bladder is a rare and severe complication but is not the most likely consequence of bladder distention in the immediate postpartum period. Bladder rupture typically occurs due to significant trauma or extreme distention, which is not common in this situation. The more immediate concern is uterine atony and hemorrhage due to displaced uterine tone from bladder distention.

D. Bladder wall atony:
Bladder wall atony could result from severe bladder distention, causing difficulty in voiding. However, this is not the most serious consequence immediately after birth. Bladder distention typically results in impaired uterine contraction, which causes bleeding rather than atony of the bladder wall itself. Addressing bladder distention will help prevent complications such as hemorrhage rather than focusing on bladder atony initially.

A. Keep the baby on his to back to sleep B. Keep the cord as dry as possible until it falls off C. Always keep the baby dressed and wrapped in 2 blankets when you go outside D. After your milk comes in your baby should have 3-4 wet or dirty diapers a day E. Have the bulb syringe near the baby at all times

Correct Answer is ["A","B","E"]

Explanation

A) Keep the baby on his back to sleep:
Placing babies on their back to sleep is the most effective way to reduce the risk of sudden infant death syndrome (SIDS). The American Academy of Pediatrics (AAP) strongly recommends this practice. Babies should not sleep on their stomach or side because these positions increase the risk of suffocation. This position should be maintained until the baby is at least 1 year old, even though many parents may be encouraged to place babies on their tummies when they start rolling over on their own.

B) Keep the cord as dry as possible until it falls off:
It is important to keep the umbilical cord stump clean and dry until it falls off, which typically happens between 1-3 weeks of life. Moisture can cause infection, so avoiding unnecessary exposure to water and keeping the stump exposed to air is essential for healing. The area should not be submerged in water until the stump falls off, and the diaper should be folded down so it doesn’t rub against it, promoting proper drying and healing.

C) Always keep the baby dressed and wrapped in 2 blankets when you go outside:
This is not an ideal practice. Overheating can be dangerous for newborns, as they have a limited ability to regulate their body temperature. Instead of wrapping the baby in two blankets, the baby should be dressed appropriately for the weather—usually in one extra layer than an adult would wear in the same conditions. This ensures the baby stays warm without the risk of overheating, which is a risk factor for SIDS.

D) After your milk comes in your baby should have 3-4 wet or dirty diapers a day:
This information is inaccurate for a 2-day-old baby. After milk comes in (usually around day 3 or 4 postpartum), the baby should be producing at least 6-8 wet diapers a day and 3-4 dirty diapers by day 4 or 5. Fewer wet diapers or a decrease in bowel movements may indicate that the baby is not feeding effectively, and it is important to monitor this carefully. In the first few days, before the milk comes in, the baby might have fewer wet diapers, but by day 3-4, this is the standard for adequate hydration and nutrition.

E) Have the bulb syringe near the baby at all times:
Having a bulb syringe nearby is a good practice in case of respiratory distress. Newborns often have mucus in their airways, and a bulb syringe can help clear their nasal passages if they are having trouble breathing. While the baby should not be suctioned too frequently or aggressively, keeping a bulb syringe available can help manage mild congestion. Additionally, in the case of sudden breathing difficulties or choking, it’s important to be prepared.
