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) Have the client void, then reassess the fundus:
A fundus that is firm but shifted to the right of the midline is a common sign of bladder distention. After childbirth, the bladder may fill with urine, which can displace the uterus and cause it to deviate from the midline, typically to the right. The first step in managing this situation is to have the client void to relieve the bladder distention, which often resolves the uterine shift. Once the bladder is empty, the nurse should reassess the fundus to see if the position returns to midline and remains firm. This is a non-invasive and effective initial intervention.

B) Encourage the client to ambulate:
Encouraging the client to ambulate could be beneficial for overall recovery, but it is not the priority action in this case. The issue at hand is a shifted fundus likely due to bladder distention, which should be addressed by encouraging the client to void first. Ambulation can be considered later when the immediate concern of bladder distention is managed.

C) Notify the healthcare provider:
While notifying the healthcare provider may be necessary if the issue persists after voiding or if there are other signs of complications, it is not the first step. The nurse should first attempt to resolve the issue through bladder emptying, as this is the most common cause of the shift in the fundus. If the problem persists after this, then further steps, including notifying the healthcare provider, would be appropriate.

D) Obtain an order for oxytocin:
Oxytocin is typically administered to help with uterine contraction and involution. However, since the fundus is firm and the primary issue appears to be bladder distention, administering oxytocin is not indicated at this time. The priority is to address the likely cause of the fundus being shifted, which is a full bladder. If the issue persists after voiding, then further intervention such as administering oxytocin may be considered.

A. Wash your hands before and after you use the bathroom and change your sanitary pad B. Do not take tub baths for eight weeks C. Use tampons instead of pads as they are better at inhibiting bacterial growth D. Douche with a mild antiseptic twice a day for two weeks, starting at day three

Correct Answer is A

Explanation

A) Wash your hands before and after you use the bathroom and change your sanitary pad:
The most important instruction for preventing postpartum infection is proper hand hygiene. The risk of infection in the postpartum period is high, especially because the perineum and cervix are healing after delivery. By washing hands before and after using the bathroom or changing sanitary pads, the mother reduces the risk of introducing harmful bacteria into the vaginal area. Proper hand hygiene helps minimize the risk of urinary tract infections (UTIs), wound infections, and endometritis, which are all common postpartum complications.

B) Do not take tub baths for eight weeks:
While it is true that taking tub baths can potentially introduce bacteria into the vaginal area, particularly if the perineum is healing from a tear or episiotomy, this is a secondary concern. The priority is hand hygiene, which directly prevents infection by limiting bacterial exposure. The recommendation to avoid tub baths is generally valid for the first 6 weeks, but it is less critical than hand washing.

C) Use tampons instead of pads as they are better at inhibiting bacterial growth:
Using tampons is not recommended in the postpartum period because they can increase the risk of toxic shock syndrome and can irritate the vaginal area or interfere with uterine healing. Pads are preferred to absorb lochia (postpartum discharge) and are safer for vaginal healing. Tampons do not inhibit bacterial growth more effectively than pads, and the use of tampons can actually increase the risk of infection, so this option is incorrect.

D) Douche with a mild antiseptic twice a day for two weeks, starting at day three:
Douching is not recommended during the postpartum period. It can disrupt the natural vaginal flora, increase the risk of infections like vaginitis, and delay the healing process. The vagina has its own natural defense mechanisms, and douching with antiseptics is unnecessary and can do more harm than good. Instead, the focus should be on keeping the area clean and dry and practicing proper hand hygiene.
