Answer:
a) probability that the first child of this couple will have Huntington's disease is 1/2 = 50%
b) probability that any six of the seven children will have Huntington's disease is 0.05468 ( 5.468% )
Step-by-step explanation:
a)Given that;Hh ( diseased father) and hh (normal)
H h
h Hh hh
h Hh hh
therefore Hh ⇒ 2 and hh ⇒ 2
so here we can see that chances of getting Huntington's disease is 1 : 1
so probability that the first child of this couple will have Huntington's disease is 1/2 = 50%b)
probability that 6 out of the 7 children will have Huntington's disease;
we use the expression: <P> = (n! / (S! × t!)) × p^S × q^t
where n! is total number of children factorial
S! is diseased number of children factorial
t! is healthy number of children factorial
p is probability of diseased children
q is probability of healthy children
so we substitute: <P> = (7! / (6! × 1!)) × 1/2^6 × 1/2^1
= (7 × 6! / (6! × 1!)) × 1/2⁶ × 1/2
= 7 × 1/64 × 1/2
= 0.05468
probability that any six of the seven children will have Huntington's disease is 0.05468 ( 5.468% )
prescription medications are designed to induce a specific effect on a neurotransmitter. many of the effects of legal and illegal drugs are due to their action on neurotransmitters. match the drug with the primary neurotransmitter it affects.
The correctly matched answers are

C) heroin with 4
D) Alcohol with 3
Serotonin and norepinephrine are released by MDMA more so than dopamine. Mood, sleep, pain, appetite, and other behaviours are significantly regulated by the neurotransmitter serotonin. The effects of MDMA that allow people to feel happier are probably due to the extra serotonin release.
Dopamine builds up at the junction of VTA cells and NAc cells as a result of cocaine use, resulting in euphoric feelings and NAc cell activity that make the brain more sensitive to more drug exposure.
Heroin strongly stimulates dopamine neurons, whereas serotonin neurons are only stimulated at higher doses. In just a few seconds, nicotine activates dopamine neurons, but it has little impact on serotonin neurons.
Alcohol increases GABA receptor activity, which slows down brain activity. It is hypothesised that this is the reason why it immediately reduces anxiety, and overdosing can result in coma. But if alcohol is constantly available, the brain's receptors adjust by producing fewer GABA receptors.

a woman has just given birth to a healthy term newborn. upon assessing the umbilical cord, the nurse would identify what findings as normal? select all that apply.
Answer: The nurse would identify one vein and two arteries as normal
Explanation:
A one-minute examination of the placenta performed in the delivery room provides information that may be important to the care of both mother and infant. The findings of this assessment should be documented in the delivery records.
During the examination, the size, shape, consistency, and completeness of the placenta should be determined, and the presence of accessory lobes, placental infarcts, hemorrhage, tumors, and nodules should be noted.
The umbilical cord should be assessed for length, insertion, number of vessels, thromboses, knots, and the presence of Wharton's jelly. The color, luster, and odor of the fetal membranes should be evaluated, and the membranes should be examined for the presence of large (velamentous) vessels.
Tissue may be retained because of the abnormal location of the placenta or because of placenta accreta, placenta increta, or placenta percreta. Numerous common and uncommon findings of the placenta, umbilical cord, and membranes are associated with abnormal fetal development and perinatal morbidity. The placenta should be submitted for pathologic evaluation if an abnormality is detected or certain indications are present.

O urinary output
O venous valves
O activity of skeletal muscles
Factors that aid venous return include pressure changes in the thorax, venous valves, and activity of the skeletal muscles except urinary output. Thus, the correct option is B.
What is Venous return?
Venous return is the rate of back flow of blood to the heart. It normally limits the cardiac output. Superposition of the cardiac function curve and venous return curve is used in hemodynamic model. The main driver force in venous return is the blood flowing back to the heart which is driven by the pressure difference between the mean systemic filling pressure and right atrial pressure (RAP).
Venous return can be facilitated by a number of different factors, such as inspiration, increased total blood volume, the cardiac suction effect, the presence of venous valves and the skeletal muscle pump.

a nurse is planning care for a client from Indonesia. What should the culturally competent nurse be aware of when completing the pain assessment?
Answer:
The nurse should identify first the language preference of the patient. Since Indonesian's primary language is not English, there could be a language barrier.
Explanation:
choose the one best answer explaining how oxaloacetate and acetyl-coa levels are balanced to maximize flux through the citrate cycle when energy charge in the cell is low.
To balance oxaloacetate and acetyl-CoA levels to maximize flux through the citrate cycle when the energy charge in cells is low, pyruvate dehydrogenase is activated by CoA but inhibited by its product Acetyl-CoA, whereas pyruvate carboxylase is activated by acetyl-CoA to produce more oxaloacetate for the reaction synthase citrate.
Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes that converts pyruvate to acetyl-CoA by a process called pyruvate decarboxylation. Acetyl-CoA can then be used in the citric acid cycle to carry out cellular reactions.
Acetyl CoA formed in the oxidation of fatty acids will enter the citric acid cycle only if the breakdown of fats and carbohydrates occurs in a balanced way. Because the entry of acetyl CoA into the citric acid cycle depends on the availability of oxaloacetate for citrate formation. But the concentration of oxaloacetate will decrease if carbohydrates are not available, or their use is not as it should be. Oxaloacetate is normally formed from pyruvate.
