A nurse is caring for a newborn who has early-onset VKDB due to maternal use of anticoagulants during pregnancy.
Which of the following interventions should the nurse anticipate for this newborn?
Administer fresh frozen plasma
Administer packed red blood cells
Administer intravenous immunoglobulin
Administer recombinant erythropoietin
The Correct Answer is A
The correct answer is choice A. Administer fresh frozen plasma. This is because fresh frozen plasma contains clotting factors that can help stop the bleeding caused by vitamin K deficiency. Vitamin K is needed for the synthesis of clotting factors in the liver, but newborns have low levels of vitamin K and may develop vitamin K deficiency bleeding (VKDB) if they do not receive prophylaxis at birth. VKDB can manifest as bleeding in various sites, such as the skin, mucous membranes, umbilicus, gastrointestinal tract, or central nervous system.
Choice B is wrong because packed red blood cells do not contain clotting factors and will not correct the underlying deficiency of vitamin K.
Choice C is wrong because intravenous immunoglobulin is used to treat immune-mediated thrombocytopenia, not vitamin K deficiency.
Choice D is wrong because recombinant erythropoietin is used to stimulate red blood cell production in anemia, not to treat bleeding disorders.
Early-onset VKDB occurs within 24 hours of birth and is associated with maternal use of drugs that interfere with vitamin K metabolism, such as anticoagulants, anticonvulsants, or antituberculosis drugs .
These drugs induce the enzymes that break down vitamin K in the fetal liver

Correct Answer is ["A","B","C","D","E"]
Explanation
The correct answer is choice A, B, C, D and E.All of these are possible modes of transmission for hepatitis B virus (HBV), which is a viral infection that attacks the liver and can cause both acute and chronic disease.The virus is most commonly transmitted from mother to child during birth and delivery, as well as through contact with blood or other body fluids during sex with an infected partner, unsafe injections or exposures to sharp instruments.
Choice A is correct because unprotected sexual contact can expose a person to the blood, semen, or vaginal fluids of an infected partner.
Choice B is correct because sharing drugs, needles, or “works” when using drugs can expose a person to the blood of an infected person.
Choice C is correct because poor infection control practices in medical settings can expose a person to contaminated needles or syringes or sharp objects that have been used on an infected person.
Choice D is correct because sharing of blood sugar (diabetes) testing equipment can expose a person to the blood of an infected person.
Choice E is correct because needle sticks or sharps exposures on the job can expose a person to the blood of an infected
Correct Answer is C
Explanation
The correct answer is choice C. A temperature of 36°C (96.8°F) is below the normal range for a newborn, which is 36.5°C to 37.5°C (97.7°F to 99.5°F).
A low temperature can indicate hypothermia, infection, or hypoglycemia, and should be reported to the provider.
Choice A is wrong because a heart rate of 140/min is within the normal range for a newborn, which is 120 to 160/min.
Choice B is wrong because a respiratory rate of 50/min is within the normal range for a newborn, which is 30 to 60/min.
Choice D is wrong because a blood pressure of 60/40 mm Hg is within the normal range for a newborn, which is 50 to 75/30 to 45 mm Hg.
