A laboring client who is positive for group B Streptococcus (GBS) is given an initial dose of 2 g of ampicillin at 9 AM. Accordi

Vikki [24]

Answer:

The next dose will be 1 g of ampicillin after 4 hours.

Intrapartum antibiotic administration to women with group B that tested ampicillin or penicillin G, either antibiotic should first be considered for(2 g of ampicillin IV followed by 1 g every four hours until giving birth.

Explanation:

Group B streptococci (GBS) colonizes the vagina and rectum in 10–30% of pregnant women.1 In the newborn, GBS is a leading cause of neonatal sepsis and a major cause of pneumonia and meningitis.2

In 2002, the Centers for Disease Control and Prevention (CDC) issued guidelines to recommend that all pregnant women be screened at 35–37 weeks of gestation for GBS and, if positive, treated with intrapartum antibiotic prophylaxis. The aims of prophylaxis are 1) to decrease colony counts at the time of delivery; 2) to prevent the organism from ascending and proliferating in the amniotic fluid compartment; and 3) to achieve adequate levels of effective antibiotic in the fetal bloodstream during labor.

For Ampicillin nonallergic patients, the protocol recommends a 2 g unit infusion of ampicillin, followed by 1 g every 4 hours until delivery.3 At least 4 hours of intrapartum antibiotic prophylaxis are recommended.

Mountain ranges form along ___ plate boundaries via orogenic processes.

Tamiku [17]

1. Mountain ranges form along <u>convergent </u>plate boundaries via orogenic processes.

<h3>What is tectonic plates?</h3>

The formation of mountains is caused by tectonic plates. A mountain is formed when two tectonic plates move towards each other and collide, resulting in altitudes that can take years to reach but that eventually create massive mountains through what are known as convergent plate borders.

2. Rift valleys formed through the stretching of divergent plates occurs through a divergent boundary process.

When tectonic plates separate, they can leave low ground areas like the Rift Valley, which are produced by diverging continental plate borders. They can be found on the surface of the Earth or at the bottom of the ocean, and they are formed by the expansion of the seabed.

3. The formation of mountain ranges occurs as a result of <u>orogeny</u>.

This process occurs when one continental plate dips and the other rises, allowing mountain ranges to form. Orogeny is the name given to this process.

4. Scientists observe an extremely long <u>deformation </u>area in a continental plate during an orogenic process..

Scientists use tectonic plate simulations to study this deformation in order to better predict natural disasters such as earthquakes.

5. <u>Epeirogenic </u>process causes vertical plate motion along tectonic plates.

The vertical movement of a continent that generates soft arcs or rises parts uniformly is known as epeirogeny.

The unwinding of DNA at the replication fork causes twisting and strain in the DNA ahead of the fork, which is relieved by an en

Eddi Din [679]

Answer:

Topoisomerase

Explanation:

Topoisomerase is an enzyme that is involved in the unwinding of Deoxyribonucleic acid (DNA). They are involved in double stranded DNA and they help to relieve the making of supercoils.

Topoisomerase play an important role during DNA replication, as the prevent the the twisting of the DNA double helix ahead of the replication fork. In other words, they ensure that the DNA open up for unwinding without being tightly wound.
