The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability
Zinaida [17]

Answer:

Explanation:

<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

            <em>Bb     x     Bb</em>

<em>            BB    2Bb    bb</em>

1.

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8

2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>

  = 3/4 x 3/4 = 9/16

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.
