You are in the delivery room caring for a preterm newborn at 27 weeks' gestation. resuscitation has been completed and the baby is ready to be transported to the neonatal intensive care unit. which of the following is a true statement about the baby???s subsequent care?
The next step is STABLE
Further ExplanationThe principle of neonatal stabilization in STABLE consists of:
S - Sugar and Safe Care
T - Temperature
A - Airway
B - Blood pressure
L - Laboratory
E - Emotional support
The word STABLE is made so that the baby helper does not forget important aspects of stabilization. In its own action does not require that it must be in accordance with the order of the word. STABLE is a stabilization action that is focused on 6 basic treatments recommended by the American Academy of Pediatrics (AAP), aimed at increasing patient safety, both in management, preventing the possibility of errors, and reducing side effects.
Resuscitation was successful: the baby cried and breathed normally after receiving the action after ventilation.
Monitoring danger signs in infants: Observing gasping for breath Observe whether the baby is whimpering Observe the pull of the chest wall Observe whether the body and lips are blue Observe whether the baby feels cold / fever Calculate the frequency of breath, whether <40X / minute or> 60X / minute Calculate the heart frequency, whether <120X / minute or> 160X / minute Observe whether the baby's body is pale Observe whether the baby's body is yellow Observe whether the baby is weak Observe whether the baby has a seizureUmbilical cord care and monitoring Monitor cord bleeding, if the ties are off, correct by the midwife Explain the correct umbilical cord care to the mother and or family If baby and normal skin color Do IMD
Prevention of hypothermia Lay the baby in a room> 250 C with his mother Catch baby (baby's skin contact to the skin of the mother) as often as possible Postpone bathing the baby for up to 6-24 hours and the baby is stable Weigh the weight covered, reduce the weight of the blanket Keep the baby warm during the examination, open the baby's blanket partially.
Provision of vitamin K1
Give an intramuscular injection of vitamin K1 1 mg in the left thigh, to prevent BBL bleeding.
Prevention of infection Provide antibiotic ointment/eye drops Giving Hepatitis B immunization 0.5 ml intramuscularly in the right thigh, 1 hour after administration of vitamin K1 Notify the mother and family on how to prevent infant infections. Physical examination
Careful physical examination of the baby after resuscitation. The initial examination is preferred for respiratory and cardiac examinations by monitoring danger signs. A complete examination should be done within 24 hours and after the baby is stable.
Carry out case records
As with any childbirth, complete a complete partograph that includes the mother's identity, pregnancy history, delivery, maternal condition, fetal condition, and LBW condition. It is very important to note the fetal heart rate because asphyxia often starts from fetal distress at delivery. If fetal distress is found write what is done. When did the amniotic rupture need to be recorded on the partograph and explain whether the amniotic fluid is mixed with meconium?
The BBL condition is also filled in on the partograph. If you experience asphyxia in addition to being recorded on the partograph, special notes should be made in a diary/notebook, simply handwritten. Try to record the membranes completely and clearly:
Mother's name, place, date of birth and time Fetal/baby conditions: Is there previous fetal distress? Is the amniotic fluid mixed with meconium? Is the baby crying spontaneously, breathing regularly, gasping for breath or not breathing? Is muscle tone good? Time to start resuscitation The resuscitation steps are taken Resuscitation results.

Attenuation is a type of regulation that can control
Attenuation is the regulatory mechanism to control gene expression or transcription. Attenuation was first observed in trp operon of E.Coli bacteria (commonly found at guts of warm blooded animal). E.Coli bacteria need tryptophan which is a kind of amino acid. The bacteria can either take tryptophan from environment or itself synthesize by using bio synthetic enzymes. These bio synthetic enzymes are encoded by five genes located next to each other which we called as trp operon.
When tryptophan levels are high, then the transcription of trp operon is controlled. This process is called Attenuation. In this process the RNA polymerase is prematurely stopped during transcription of trp operon which results in formation of short mRNA. Due to premature control such mRNA doesn’t gets encoded with tryptophan biosynthesis enzymes.
Attenuation is carried out when tryptophan level is high, so as to prevent unnecessary production of biosynthetic enzymes which are needed to make tryptophan.
Which of the following is true of hydrogen bonds
A. Hydrogen bonds are strong
B.hydrogen bonds make the positive sides of water molecules stick to each other
C.hydrogen bonds are not strong but there are plenty of them in a drop of water.
Hydrogen bonds are not very strong, but there are many of them in a drop of water, making them crucial for the properties of water.
Explanation:The correct answer to the question is that hydrogen bonds are not inherently strong, but there are plenty of them in a drop of water, which makes them vital for water's unique properties (option C). A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Although they are weak when compared to covalent bonds, they are nevertheless very necessary for the properties of water due to their large quantity.

Julia had a sibling who died because of a genetic disease as an infant. Before having children, she and her husband Tobias get genetic testing and counseling. They are unlucky.
For the GAA gene, Julia has one normal allele and one totally non-functional allele. Tobias has one normal allele and one totally non-functional allele.
If any of their offspring test positive for Pompe disease, when are symptoms likely to develop (remember, both parents have one non-functioning allele, 0%GAA)?
1.) Before the age of nine months
2.) Anytime during adolescence up through middle adulthood.
The right answer is A.
It turns out that this family possesses in their gene the infantile form of Pompe disease, so the disease will appear early in the offspring.
Pompe disease is caused by a deficiency of lysosomal acid α-glucosidase resulting from mutations in the GAA gene. The clinical spectrum ranges from a rapidly fatal multisystem disorder (classical, beginning before 1 year) to less severe myopathy in adults.

Explanation:
How does an f+ cell differ from an hfr cell? how does an f+ cell differ from an hfr cell? hfr strains have the f plasmid integrated into the chromosome. f+ cells have no plasmids. hfr cells cannot perform conjugation. hfr strains can no longer reproduce?
In summary , the most difference between an F+ cell and an Hfr cell are the area of the F plasmid (extrachromosomal vs. coordinates into the chromosome) and the degree of DNA exchange amid conjugation.
Bacterial cell explained.
An F+ cell and an Hfr cell are both sorts of bacterial cells that have the F plasmid, too known as the richness calculate. In any case, there are critical contrasts between them:
F+ Cell (F-Positive Cell):
An F+ cell carries the F plasmid as an extrachromosomal circular DNA atom partitioned from the bacterial chromosome.The F plasmid in an F+ cell can duplicate autonomously and is competent of conjugation, which is the exchange of hereditary fabric to a beneficiary cell.F+ cells can act as givers amid conjugation and can exchange the F plasmid to an F- (F-negative) cell, changing over it into an F+ cell.Hfr Cell (High-Frequency Recombination Cell):
An Hfr cell moreover carries the F plasmid, but it is coordinates into the bacterial chromosome instead of existing as a isolated plasmid.Integration of the F plasmid into the chromosome comes about in an Hfr strain.Hfr cells have the capacity to perform conjugation and exchange both chromosomal and plasmid DNA to beneficiary cells amid conjugation.However, the exchange of the whole F plasmid from the Hfr cell to the beneficiary cell is regularly fragmented, because it requires the replication and recombination of the coordinates F plasmid with the beneficiary chromosome.
It's imperative to note that Hfr strains can still replicate, and they hold the capacity to perform conjugation. In any case, the total exchange of the F plasmid and chromosomal DNA to the recipient cell seldom happens amid conjugation with Hfr cells.
In summary , the most difference between an F+ cell and an Hfr cell are the area of the F plasmid (extrachromosomal vs. coordinates into the chromosome) and the degree of DNA exchange amid conjugation.

d. hydrogenation
Answer is fusion, according to e2020. Just took the quiz
Answer:
a. fusion
Explanation:
The Sun's energy is produced at its core through a process that is referred to as nuclear fusion. The type of nuclear fusion involved in the production of energy at the Sun's core is known as Hydrogen fusion.
Hydrogen fusion is a nuclear fusion reaction whereby two atoms of hydrogen form or produce four hydrogen nuclei. These four hydrogen nuclei come together or fuse together to form one helium atom. During this reaction, some mass of hydrogen is changed or converted to light energy in the Sun.
The neurons of the central nervous system are also known as ________.
Final answer:
The neurons of the central nervous system are specialized cells that make up the brain and spinal cord, crucial for processing and transmitting sensory information.
Explanation:
The neurons of the central nervous system are also known as the fundamental building blocks of the central nervous system (CNS), which includes the brain and the spinal cord. The CNS is central because it processes sensory information, like touching a hot stove or seeing a rainbow, and then sends signals for action through the peripheral nervous system (PNS). Neurons are specialized cells that transmit information via electric signals and form connections with other neurons at synapses. There are approximately 100 billion neurons in the human brain, each with the capability of creating numerous synapses. The structure of neurons consists of a dendrite, a soma, and an axon that collectively facilitate the reception and transmission of information within the nervous system.
