Answer:
D - High Arousal; Low Arousal
Explanation:
The Yerkes Dodson law explains the relationship between arousal and performance. It was posited by Robert M. Yerkes and John Dillingham Dodson in 1908.
The law asserts that there is a direct relationship between arousal and performance. An increase in arousal up to a certain level will enhance performance, and once the optimal threshold is exceeded, performance will begin to decline.
Thus arousal should be kept at a midpoint as too little causes boredom, and too much causes hyperactivity, so moderate arousal is optimal.
A simple task requires higher arousal because it uses less cognitive function and brain power thus higher arousal is required to keep interest; while a difficult task requires low arousal since it requires higher cognitive function, it requires lots of focus and higher arousal is not good for intense focus as it causes hyperactivity.
The Yerkes-Dodson law states that the performance on simple tasks is best with high arousal, while complex tasks require low arousal for optimized performance.
Explanation:According to the Yerkes-Dodson law, successful performance on a simple task requires high arousal, whereas successful performance on a difficult and complex task requires low arousal. The correct answer is d) high arousal; low arousal. The Yerkes-Dodson law suggests that there is an inverted U-shaped relationship between arousal and task performance, meaning that moderate levels of arousal are optimal for task performance.
However, the peak of the curve shifts depending on the complexity of the task, with higher arousal being more beneficial for simple tasks and lower arousal levels being more advantageous for complex tasks. This is because high arousal can help maintain concentration on simple tasks, while it can be overwhelming and harmful to performance on complex tasks.
A painful sensation in the chest that results from gastric juices seeping back up into the esophagus is called _____.
Answer:
Gastroesophageal reflux.
Explanation:
Human's body secretes different juices and enzyme that helps in the process of digestion. Each juice is secreted into the specific component of the digestive system.
The gastric juice is present in the stomach but sometimes this juice can get into the esophagus. This causes the burning and painful sensation in the chest known as gastroesophageal reflux. This medical conditions needs to be treated properly.
Thus, the correct answer is gastroesophageal reflux.
Heartburn is the painful sensation resulting from gastric juices seeping back into the esophagus due to issues with the gastro-esophageal sphincter. Although it is painful and often mistaken for a heart attack, it does not indicate a heart condition.
Explanation:A painful sensation in the chest that results from gastric juices seeping back up into the esophagus is called heartburn.
Heartburn occurs due to acid reflux, where acidic digestive juices escape into the esophagus. This usually happens when there's a malfunction in the gastro-esophageal sphincter, a ring-like muscle that prevents the contents of the stomach from traveling up the esophagus. When we swallow, this sphincter opens up to let food pass into the stomach and closes when there's no swallowing. Hence, acid reflux, or heartburn, often occurs when this sphincter fails to close properly or opens at the wrong time.
Please note that although the sensation can be quite painful and is often mistaken for a heart attack, heartburn is a completely different condition linked to the digestive system, not the cardiovascular system, and doesn't have any correlation with heart diseases like angina pectoris.

Which of the following statements about BPA and phthalates is false?
A. They are components of plastic
B. They are used in food and drink containers
C. They have been found in the blood of Americans
D. They have been proven to cause obesity and diabetes
Answer:
They have been proven to cause obesity and diabetes
Explanation:
Bisphenol A (BPA) and phthalatees are also known as everywhere chemicals because they are present and very common in nature. The items that constitute BPA and phthalates are plastic bottle, toys and sippy caps.
Phthalates and BPA are present in the body of people especially in Americans. These chemicals might cause a danger for the couples that expect baby. These chemicals acts as a powerful tetratogen that might cause abnormality in the infants. These chemicals are not associated with diabetes and obesity.
Thus, the correct answer is option (D).
The false statement about BPA and phthalates is that they have been proven to cause obesity and diabetes, which is not established. BPA is used in polycarbonate plastics and epoxy resins for packaging food and drinks while phthalates make plastics flexible.
Explanation:The false statement about BPA and phthalates among the options provided is D. They have been proven to cause obesity and diabetes. While studies suggest that BPA and phthalates can affect the reproductive system and hormone function, definitive proof that they cause obesity and diabetes is not established. Bisphenol A (BPA) is a chemical used primarily in the production of polycarbonate plastics and epoxy resins found in many consumer products such as food and drink packaging, including cans and plastic bottles. Phthalates, also present in various plastics, are used to make plastics more flexible. These compounds have been found in human tissues, including blood, due to their prevalence in consumer products and packaging.
It's important to note that exposure to these chemicals is widespread, as they can leach into foods from containers, and they have been detected in the blood of a large percentage of Americans. However, the link to specific health conditions like obesity and diabetes is still under investigation, making statement D the false claim.

Which food has the greater nutritional density of vitamin C: (a) an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories, or (b) an 8-ounce serving of a sport drink that contains 175 milligrams of vitamin C and has 250 calories?
Answer: (a) an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories
Explanation:
Nutrient density or nutritional density reflects the ratio of the nutrient content to the total energy content of the food. Therefore the nutrient density is expressed in terms of the amount of a specific nutrient (in weight) per 1000 calories or joules
Comparing the nutritional density of the two drinks;
(a) For an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories(111/1000 Kcal) or 0.111Kcal
nutritional density = 125mg/0.111Kcal = 1126.126 mg/Kcal
(b) For an 8-ounce serving of a sport drink that contains 175 milligrams of vitamin C and has 250 calories(250/1000 Kcal) or 0.250Kcal
nutritional density = 175/0.250Kcal =700 mg/Kcal.
Therefore, an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories has a greater nutritional density of Vitamin C than an 8-ounce serving of a sport drink that contains 175 milligrams of vitamin C and has 250 calories.

The health care provider determines the maximum tolerable dose of isosorbide dinitrate (Isordil) by increasing the dose until what happens?
Answer:
Several reactions could happen after the increase of the dose, but the most important and dangerous is the abrupt decrease of blood pressure.
Explanation:
Isordil (isosorbide dinitrate) is a medicine used for the treatment of angina or heart failure. This drug is for oral or sublingual use. It acts as a vasodilator that helps to relax smooth muscle while reducing chest pain.
In addition to the smooth vascular muscles, Isordil relaxes the bronchial, biliary, gastrointestinal, urethral and uterine smooth muscles. Nitrates are physiological antagonists of norepinephrine, acetylcholine and histamine. Following administration of therapeutic doses of the drug, systemic blood pressure is generally decreased; heart rate is unchanged or slightly compensatory increase.
If the dose was increase more than the tolerable, would happen: immediate abrupt decrease in blood pressure; persistent throbbing headache; dizziness; palpitation (feeling of rapid and strong heartbeat); visual disturbances; erythema and sweating (then the skin becomes cold); nausea and vomiting (possibly with colic and even bloody diarrhea); fainting (especially in the upright position); initial hyperpnea (increased respiratory rate), dyspnea (shortness of breath) and slow breathing; slow pulse; cardiac arrest; increased intracranial pressure with symptoms of confusion and moderate fever; paralysis and coma followed by convulsions and possibly death due to circulatory collapse.
The maximum tolerable dose of isosorbide dinitrate (Isordil) is determined by increasing the dose until the patient encounters unacceptable side effects, balancing medication efficacy with patient comfort.
The health care provider determines the maximum tolerable dose of isosorbide dinitrate (Isordil) by increasing the dose until the patient experiences side effects that are no longer deemed acceptable. Isosorbide dinitrate is a medication used to prevent and treat angina (chest pain) by widening blood vessels to improve blood flow to the heart muscle. However, increasing the dose can lead to side effects such as headaches, dizziness, or hypotension. The goal is to find the highest dose that the patient can tolerate without experiencing these adverse effects.
Here are the points to remember:
The safety of patients comes first: Healthcare professionals put their patients' safety and well-being first and abstain from anything that could endanger them.It's crucial to practice ethics: Creating adverse effects to figure out the highest dose that may be taken is unethical and goes against medical ethics.Customized strategy: The ideal dosage may change depending on the particular requirements of the patient and how they react to the drug.If a child has a human hormone deficiency he or she may not grow taller than 5 feet of a?

Phil and Sarah bought a life policy in which both are insured. Sarah dies before Phil. If the policy pays the death benefit after Phil dies, it is a:
Answer:
Survivorship life.
Explanation:
Life insurance may be defined as the policies that provide the beneficiaries to the individual with the sum payments. This beneficiary is beneficial when the individual dies.
The survivorship life is a type of life insurance and the type of the variable life insurance of the policy that individually covers the two individual. This policy pays the death benefit to the individual beneficiary only after the death of the two people.
Thus, the answer is survivorship life.
Phil and Sarah's policy, which pays out only after both insured parties have died, is known as a survivorship or second-to-die life insurance policy. These policies are particularly useful in estate planning, offering financial protection and peace to heirs. The life insurance landscape also features innovative practices like life settlements, impacting costs and policy management.
Explanation:Phil and Sarah purchased a life insurance policy with both of them as insured parties. This type of policy, which pays out the death benefit only after the second person dies, is known as a survivorship or second-to-die life insurance policy. Survivorship policies are often used for estate planning purposes, allowing the remaining policy proceeds to cover estate taxes or provide for heirs without burdening the surviving spouse. Cash-value (whole) life insurance, one of the types of policies that can incorporate the survivorship feature, blends a death benefit with a savings element, accumulating value over time that the policyholder can use.
The life insurance sector has evolved with practices like life settlements, where policies are transferred to third parties who continue premium payments and collect benefits upon the death of the insured. This has impacted life insurance costs and practices significantly. Yet, the core purpose of life insurance is to offer financial protection and peace to the survivors of the insured, with some policies offering the flexibility of cash withdrawals or loans against the accrued cash value.
