Answer:
trying to be good
Explanation:
Men with a repressive coping style who experience chronic or excessive stress may have sharp increases in blood pressure and heart rate, leading to psychophysiological disorders primarily caused by stress.
Researchers have found that men with a repressive coping style are inclined to have a significant increase in blood pressure and heart rate when stressed. This stress response, often seen as the fight-or-flight reaction, is driven by the activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. Such rises in blood pressure and heart rate can contribute to the prevalence of psychophysiological disorders where the primary cause is excessive and chronic stress.
For instance, frequent exposure to stressors, such as job strain, natural disasters, or marital conflict, has been linked to cardiovascular issues. When individuals experience strong negative emotions in response to daily stressors and respond to stress with hostility, they're more likely to encounter adverse health outcomes, including hypertension and heart disease.
It is crucial to note that stress reactions that consistently exceed normal ranges or chronic stress can lead to wear and tear on the body, similar to overusing a machine, increasing the risk of health problems related to stress, such as heart attacks.

Answer: The mother's nutrition-related advice about the benefit of taking the gelatin pills is an example of an anecdote.
Explanation:
In medicine, an anecdote is when a person uses something that may of worked for them previously. In this case, it was gelatin pills 3 times a day. There is no scientific research that shows that this will really help fingernails, but people will use it because of others success with it.
Final answer:
Emily's mother advises her to take gelatin pills to strengthen her brittle fingernails, based on the belief that gelatin can improve nail health due to its collagen content. Fingernails are made of keratin, which makes them tough but flexible. However, the effectiveness of gelatin supplements for this purpose has mixed scientific support.
Explanation:
Emily has brittle fingernails that frequently crack and split. Her mother's advice to take gelatin pills three times a day is based on the belief that gelatin can strengthen fingernails. This advice is an example of a dietary recommendation based on the component keratin, which is crucial for the strength and health of nails. Nails consist of dead keratinocytes filled with keratin, making them tough yet flexible.
Keratin is a structural protein that plays a key role in the health of nails, skin, and hair. While some believe that consuming gelatin (which is a form of collagen and a source of amino acids) can help improve nail strength, scientific evidence on the efficacy of gelatin supplements for nail health is mixed.
Fingernails serve important functions, such as protecting the fingertips and enhancing sensation, by acting as a counterforce when objects are handled. They are made up of a nail plate, nail matrix, and nail bed below it. The advice given by Emily's mother is rooted in the nutritional approach to improving nail health, although it's important for individuals to also consider other factors that could influence nail health, including overall diet, health conditions, and external factors that may cause damage to the nails.
While you are returning from lunch, a frantic woman flags you down and states that she just found a young child on the roadside who appears to have been hit by a car. She is not sure if the child is breathing. You should immediately:A) inform the woman that she will need to calm down.B) advise dispatch that you have been flagged down for a possible emergency.C) grab equipment and get to the child's location.D) call for paramedic assistance and await their arrival.
Answer:
The answer to the question: You should immediately... while talking about a woman who flagged you after lunch to inform you that she has found a young child by the roadside, who seems not to be breathing, and who seems to have been hit by a car, would be, B: Advise dispatch that you have been flagged down for a possible emergency.
Explanation:
The reason for this being the correct answer, instead of simply calling for assistance, calming the woman down, or grabbing your equipment and getting to the child´s location is that you have been informed of a possible emergency, but you are not yet sure of what exactly has happened, and if everything the woman has related, is accurate. As such, the first thing you need to do is inform dispatch that you have been informed of a possible situation so that they ready the necessary support in case the emergency is real, and it is all that was made out to be. Then, you must go and assess the situation.
In this situation, the correct action to take is to grab equipment and get to the child's location. Assess the child's condition and provide immediate assistance. Time is of the essence, so acting quickly is important.
Explanation:In this situation, the correct action to take is option C: grab the equipment and get to the child's location. As a first responder, it is important to act quickly and provide immediate assistance to the child.
Once you reach the child, you should assess the situation and check their breathing and pulse. If the child is not breathing, you should perform CPR while waiting for paramedic assistance to arrive.
It is crucial to remember that time is of the essence in emergency situations, and taking prompt action can greatly increase the chances of saving a life.

A group of nursing students are studying information about childhood cancers in preparation for a class examination. They are reviewing how childhood cancers differ from adult cancers. The group demonstrates understanding of the information when they identify what location as an unlikely site for childhood cancer?
1) Brain
2) Kidney
3) Lymph
4) Bladder
Answer:
The best answer for the statement: The group demonstrates understanding of the information when they identify what location as an unlikely site for childhood cancer, would be, 4) Bladder.
Explanation:
Talking about cancer in children is already hard enough. Their bodies, which are so new, should not be undergoing a condition that was once thought to be an attribution of old age. However, statistis show a rise in the prevalence of cancer in children, as well as adults. Incidence of cancer, and locations of such a condition, differ between adults and children, with children having, unfortunately a high incidence of lukemias, followed by tumors in the brain, lymphatic system, kidneys, muscles and bones. However, one cancer type that is not prevalent in children, is bladder cancer. This is a type that is most prevalent in adults, though it cannot be said that it will never appear. However, it is not common.

Mrs. Walters is enrolled in her state’s Medicaid program in addition to Medicare. What should she be aware of when considering enrollment in a Medicare Advantage plan?
Answer:
Medicaid will coordinate benefits only with Medicaid participating providers
Explanation:
Medicaid is a program funded and administered by federal and state governments. Firstly, it is a law program, different from Medicare, in that it is a social care program based on basic needs. Eligibility for Medicaid depends on the person's age (over 65) or a physical or mental disability that requires them to seek medical attention. Financial criteria based on income and assets are then evaluated. Regarding Medicaid, a client considering enrolling in the Medicare Advantage plan should be aware that Medicaid will only coordinate benefits with participating Medicaid providers.
Final answer:
Mrs. Walters, enrolled in both Medicare and Medicaid, should understand the network restrictions and additional benefits of Medicare Advantage plans, as well as how these plans may interact with her Medicaid coverage. She should thoroughly review plan details for any potential impacts on her current health care services and provider availability.
Explanation:
Mrs. Walters, who is enrolled in both Medicare and Medicaid, should be informed about the implications of enrolling in a Medicare Advantage plan. It is important to note that Medicare is a federally funded health insurance program primarily for individuals 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease (ESRD) or ALS. Medicaid is a joint federal and state program that assists eligible low-income individuals and those with disabilities in accessing health care. A crucial aspect Mrs. Walters must consider is that fewer health care providers may accept Medicaid due to lower payments compared to Medicare; this is a factor when choosing a Medicare Advantage plan as it can limit the network of available providers.
Medicare Advantage plans, also known as Part C, are an alternative to original Medicare (Part A and Part B) and typically offer additional benefits, potentially including prescription drug coverage (Part D), dental, vision, and wellness programs. However, these plans often come with specific network restrictions, requiring care to be provided through in-network doctors and hospitals. Since Mrs. Walters also receives Medicaid benefits, she should review the compatibility of her Medicaid coverage with any Medicare Advantage plan she is considering to ensure she doesn't lose access to her current doctors or health services provided by Medicaid.
It is essential for beneficiaries like Mrs. Walters to understand the coverage details and cost implications of enrolling in a Medicare Advantage plan while on Medicaid. These include weighing the additional benefits against potential network limitations and costs associated with the Advantage plan. Detailed plan comparisons and discussions with Medicare representatives or healthcare advisors can provide clarity on the best options for her specific situation.

When should clients, who don’t require PPIs or H2 inhibitors, take their antacids?
a) Routinely before meals
b) Routinely after meals
c) Whenever heartburn occurs (prn) Q.I.D.
d)At bedtime only
Answer:
c) Whenever heartburn occurs (prn) Q.I.D.
Explanation:
Antacids are OTC drugs (no prescription needed) used to treat heartburn. They are usually salts (aluminium, calcium or magnesium) that neutralize the excess of acid in the stomach.Examples of antacids are: Pepto Bismol (P&G), Maalox (SANOFI) and Tums (GSK)There are other types of medications that control heartburn, but they do it through a different mechanism: instead of neutralizing the excess of acid, they inhibit the production of acid in the stomach. These are: PPIs (Proton Pump Inhibitors) and H2 inhibitors/blockers. These medications have important side effects and interactions, which is why they shouldn't be taken instead of an antacid to relief sporadic heartburn symptoms.Ranitidine (Zantac, by SANOFI) is an example of an H2 inhibitor, and Pantoprazole (Protonix, by Pfizer) is an example of a PPI.People who present heartburn only from time to time and have no underlying reflux disease are not prescribed PPIs or H2 inhibitors. It is advised that they take antacids after meals when heartburn occurs, but not in a routinely manner and not for more than 2 weeks. If symptoms persist or worsen, clients should see a doctor.Diet and lifestyle changes are also recommended for people who present heartburn; these include: avoiding foods that trigger it such as fried and spicy food & carbonated beverages, eating smaller meals, maintaining a healthy weight, avoiding smoking, and avoiding lying down after eating.You are completing an assessment of a client with end stage liver disease. Which of the following findings is most important to notify to the physician?
A. Expanding ecchymosis
B. Ascites and a serum albumin of 3.2g/dl
C. HCT of 37% and a HGB of 12g/dl
D. Occasional disorientation and forgetfulness
Answer:
A. Expanding ecchymosis
Explanation:
Terminal liver disease occurs when the liver cannot effectively participate in the body's detoxification process and all other metabolism functions and can cause signs and symptoms such as jaundice, swelling or even brain damage. This disease is the most serious consequence of chronic liver disease and can lead to death if a transplant is not performed.
Some situations may aggravate the patient's condition and therefore should be notified to the attending physician promptly. One such situation is the expansion of bruise. Bruise is a subcutaneous bleeding that can cause a major problem in patients with end-stage liver disease.
A nurse is teaching a class on X-linked recessive disorders. Which of the following statements would the nurse most likely include?A) Males are typically carriers of the disorders.B) No male-to-male transmission occurs.C) Daughters are more commonly affected withthe disorder.D) Both sons and daughters have a 50% risk ofthe disorder.
Answer:
B) No male-to-male transmission occurs
Explanation:
X-linked recessive disorder are passed via X chromosomes. A female with two recessive alleles will have the disorder while a female with one recessive allele will be a carrier. Since a male has only one X chromosome, having a single copy of the recessive allele is enough to make him affected. Hence, males can not be carrier of these disorders, they will either be affected or unaffected.
Sons are also more commonly affected by this disorder since they require only one recessive allele to express it. Since males pass on Y chromosome to sons and not X chromosome, male to male transmission of the disorder is not possible.
A nurse teaching about X-linked recessive disorders would indicate that no male-to-male transmission occurs, as males cannot be carriers. While sons have a 50% chance of being affected, daughters have a 50% chance of being carriers, not of being affected.
Explanation:When teaching a class on X-linked recessive disorders, a nurse would most likely include the statement that no male-to-male transmission of the disorder occurs. This is due to the fact that males have only one X chromosome and any gene mutation on it will express the disorder rather than the individual becoming a carrier. Specific characteristics of X-linked recessive disorders include:
Females can be carriers of the disease and have a 50% chance of passing the gene to their offspring. However, they will typically not display symptoms of the disorder since they have two X chromosomes and the normal one will compensate for the defect.Males who inherit the mutated gene will be affected by the disorder because they have only one X chromosome and no backup copy to offset the mutation.Daughters of a carrier mother and an unaffected father have a 50% chance of being carriers themselves. They will not be affected unless they receive a recessive gene from both parents.Sons of a carrier mother have a 50% chance of being affected as they receive only one X chromosome from their mother.Therefore, the accurate statement among the options given would be 'B) No male-to-male transmission occurs.' Since males cannot be carriers, they cannot pass on a carrier status. Similarly, as the daughters can be carriers, the risk of them being affected is not the same as for sons.
A nurse is educating a client on the basal body temperature method as a form of contraception. Which statement by the client indicates and understanding of when she can expect to see a rise in her temperature?
Answer:
"Immediately following ovulation my temperature will increase."
Explanation:
One type of contraceptive method is basal temperature, which is based on body temperature analysis to detect the fertile period. This measurement should be done daily, for graphing, and with the body at rest (after at least six hours of sleep). The temperature should always be measured with the same thermometer to avoid variations. In case of breakage, the material change should be noted on the chart. The place to check the temperature can be oral, rectal or vaginal and should be the same for the entire cycle.
During the woman's cycle, at the time of ovulation, the yellow body, which secretes estrogen and progesterone, forms. The latter is related to the rise in temperature by a few tenths of a degree due to its thermogenic effect. To confirm that this phase has begun, it is important for the woman to understand if there was a difference of at least 0.2ºC between one temperature and another. For this reason, the client exposed in the question, shows that she understood everything about this contraceptive method when she says "Immediately after ovulation, my temperature will rise."
Early recognition of cardiac arrest and activation of an emergency response protocol; immediate high-quality CPR; rapid defibrillation; effective BLS and ALS care and transportation; and effective post-cardiac arrest care at a hospital are the links in which chain of survival?

Explanation:
The American Hearth Association, in 1991, release this publication, in which is mention all the steps to be done in case of a cardiac arrest. Since this incident occurs suddenly, any person from the community can act to help a person in case of cardiac arrest. Al least until the EMS personnel are in the place of the incident.
A client is being admitted to the medical unit after being seen in the emergency department. Which statement by the nurse indicates an understanding of the importance of the appropriate timing of a health assessment?
Answer:
"I'm going to assess the client now so that I can begin formulating the care plan."
Explanation:
Whenever a patient needs to be interned, it is important for the medical staff to create a care plan specific to that patient's problem. Only in this way will the patient have the chance to improve his health and leave the hospital as soon as possible. This care plan can only be formulated after a nurse assesses the patient's condition. For this reason, the best statement that the nurse can make in the case of the patient exposed in the question is "I'm going to assist the client now that I can begin formulating the care plan."

A patient was climbing a ladder, slipped on a rung, and fell on the right side of the chest. X-ray studies reveal three rib fractures, and the patient is complaining of pain with inspiration. What is the anticipated treatment for this patient?a. Chest strappingb. Mechanical ventilationc. Coughing and deep breathing with pillow splintingd. Thoracentesis
Answer:
The correct answer for the question: What is the anticipated treatment for this patient, when talking about a patient who fell from a ladder, fell on the right side of the chest, was shown to have three ribs fractured and is now having pain at inspiration, would be: Coughing and deep breathing with pillow splinting.
Explanation:
This type of procedure can be done by healthcare professionals and it can also be done by the patient, and it will help with the pain as it will protect the injured area when using the pillow, retain the excessive expansion of the chest while inspiring, and the coughing will help with relaxation of the muscles, while deep breathing will allow the chest cavity to function but without much mechanical injury, caused by rapid breathing, or excessive expansion. The point is to use a pillow as a splint, and ask the patient to hold it against the chest, while inspiring. The coughing will help the muscles relax, and increase oxygenation, the deep breathing will further enhance oxygenation, without overexerting the chest cavity, and thus the ribs, and the pillow splint will further protect the injury site by becoming almost a limit to the expansion of the chest. In the case of this patient, given his injury, it is the most effective treatment to use.

Kyle, a 5-year-old boy, has been growing by leaps and bounds; his height is 100% above normal for his age. He has been complaining of headaches and vision problems. A CT scan reveals a large pituitary tumor.
A) Which hormone is being secreted in excess?
B) Which condition will Kyle exhibit if corrective measures are not taken?
C) What is the probable cause of the headaches and visual problems?
Answer:
The human body thrives on the balance of all its factors, including hormones that mediate the responses that our bodies give in different circumstances. During childhood development, these balances are vital for normal functioning. In Kyle´s case, this balance has been disrupted completely by the appearance of a pituitary tumor, which is clearly affecting the secretion of hormones, especially those who make his body enlarge and grow. Given this small background, the answers to your questions, are:
1. The hormone that is being affected by being secreted in excess by the pituitary is the hGH, human growth hormone, also known as somatotropin. It is the one responsible to signal all cells of the body to allow growth and development.
2. The condition that Kyle will exhibit if the corrective measures are not taken in time, is known as gigantism, or giantism. A condition in which the body enlarges beyond what is expected and there is disbalance in the height, and size of certain parts of the body.
3. The probable cause of the headaches and also the visual problems that Kyle is displaying is that the tumor in the pituitary is growing to protrude inferiorly from the gland and it is probably pressing on the optic chiasma of the child.

Aaron complains to his parents that he is experiencing significant pain in his right leg, and he does not have much of an appetite. Aaron's father takes him to the doctor for a thorough exam. After getting lab results, the doctor reports, "The pain is his leg is likely due to the presence of misshapen red blood cells." Of the following disorders, which is the most likely diagnosis of Aaron's condition?
A) Sickle-cell anemia
B) Down syndrome
C) Tay-Sachs disease
D) Klinefelter's syndrome
Answer:
A) Sickle-cell anemia
Explanation: People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
The most likely diagnosis of Aaron's condition is A) Sickle-cell anemia.
Sickle-cell anemia is a genetic disorder characterized by the presence of misshapen red blood cells, which can lead to pain in various parts of the body, including the legs. This condition is caused by a mutation in the hemoglobin gene, which results in abnormal hemoglobin known as hemoglobin S. The red blood cells become rigid and sickle-shaped, leading to a variety of complications, including pain crises, anemia (due to the rapid breakdown of the abnormal red blood cells), and increased susceptibility to infections. The symptoms Aaron is experiencing, such as significant pain in his leg and a decreased appetite, are consistent with the vaso-occlusive crises that occur in sickle-cell anemia, where the sickle-shaped cells can block blood flow to certain areas of the body.
The other options listed do not directly relate to the symptoms described:
B) Down syndrome is a genetic disorder caused by the presence of an extra chromosome 21 (trisomy 21). It is associated with a range of physical and intellectual disabilities, but it does not typically cause misshapen red blood cells or leg pain as seen in Aaron's case.
C) Tay-Sachs disease is a rare genetic disorder that results in the destruction of nerve cells in the brain and spinal cord. It is characterized by progressive neurological deterioration, but it does not cause misshapen red blood cells.
D) Klinefelter's syndrome is a condition that occurs in males when they have an extra X chromosome. It can lead to a variety of developmental and physical abnormalities, but it is not associated with the presence of misshapen red blood cells.
Therefore, based on the symptoms of leg pain and the lab results indicating misshapen red blood cells, sickle-cell anemia is the most likely diagnosis for Aaron's condition.
Juliana's uncle was diagnosed with gallbladder disease. Eventually he had to have his gallbladder removed. Juliana, a biology major, knew that the gallbladder is necessary for fat digestion and worried about her uncle's long-term health. How does his body digest fat without this accessory organ?A. His body cannot digest fat and he needs to avoid all fat for the rest of his life.B. His liver continues to produce bile for fat metabolism, but the bile is secreted directly into the duodenum.C. Since his body cannot store bile, he must take bile in the form of a supplement with meals.D. His body does not produce gastric lipase, and he must take a gastric lipase supplement with meals.
Answer:
Option (B).
Explanation:
Bile is an important digestive juice that helps in the emulsification of fat. Bile is produced in the liver and stored in the gall bladder before releasing into the intestine.
Any injury in gallbladder may results in the removal of the gallbladder of the organism. After removal of bladder, the bile is produced by liver but can not be stored in the organ. The bile is directly passed into the duodenum and helps in the digestion of lipids.
Thus, the correct answer is option (B).
The liver continues to produce bile for fat digestion after gallbladder removal, secreting it directly into the duodenum. The body can still digest fats without the gallbladder, although dietary adjustments might be necessary.
Explanation:Juliana's concern about her uncle's ability to digest fat after gallbladder removal is common. However, the liver continues to produce bile, which is necessary for fat metabolism. After gallbladder removal, bile is no longer stored and concentrated but is instead secreted directly into the duodenum.
Even without a gallbladder, the liver still aids in digestion by continuously secreting a more dilute bile into the duodenum, where it emulsifies fats, making them easier for digestive enzymes to break down. Surgical removal of the gallbladder doesn't seriously affect digestion for this reason, although some patients may need to adjust their diets to smaller, more frequent meals to accommodate the more constant flow of bile into the intestines.

Answer:
c) one
Explanation:
Piaget theory states that a child can modify it reflections. In this stage the child starts to search or experiment certain like using it senses like the fingers, the smell, the suck. This is also associated with the security of the mother, because is a natural reflex of how the sucking is an automatic reflex to cover the security and the need of the child.
Freddy is in stage three of Piaget's sensorimotor development, where he can act on his own preference, demonstrated by his continued thumb sucking despite being offered a pacifier.
Explanation:Freddy is demonstrating behaviors aligned with stage three of Piaget's theory of sensorimotor development. In this stage, which happens typically between 4-8 months of age, babies start to act on objects outside them. They can protrude objections, including their own body parts, not only due to reflexes but because they have learned to do so.
This is exhibited in Freddy's proclivity to continue to suck his thumb even when offered a pacifier. He has reached a stage in his development in which he can express an independent preference and choice, indicating a disconnect between his desired action (thumb sucking) and the option presented by his parents (using a pacifier).

A scientist, Dr. Sigma, states that a chemical taken internally once a day will prevent the common cold. However, no other scientist is able to duplicate the results. The statement by Dr. Sigma is ___.a. a lawb. a hypothesisc. a theoryd. not valid
Answer:
d. not valid
Explanation:
In the scientific method an experiment is a set of actions about phenomena. The experiment is fundamental in the empirical approach to the acquisition of a deeper knowledge about the physical world. Depending on the philosophical perspective an experience can lead to objective and complete understanding of the physical world or just an aid in improving subjective knowledge through fallibilism. Dr. Sigma's statement about a chemical that if taken internally once a day will prevent the common cold, must have come about through a scientific experiment. However, Dr Sigma's conclusions cannot be considered valid.
This is because, for the conclusions made through an experiment to be considered valid and correct, other scientists must be able to duplicate the results. No scientist has been able to duplicate the results found by Dr. Sigma, so we can conclude that Dr. Sigma's statement is invalid.
