Answer and Explanation:
Ergotamine has been used for over 50 years and was the first specific drug to treat migraine attacks. Its therapeutic effect is due in part to its ability to contract the vessels. It is a vasoconstricting alkaloid used in migraine attacks, when treatment with non-steroidal anti-inflammatory drugs has no effect.
The mechanism of action of ergotamine is complex. The molecule has structural similarities to neurotransmitters such as seratonin, dopamine and adrenaline, and can therefore bind to various receptors and function as an inhibitor. Its use in the treatment of migraines is due to its vasoconstrictor effect of extracerebral intracranial blood vessels through their binding to the 5-HT1B receptor and inhibition of neurotransmitter binding.
Overuse of ergotamine may cause nausea, vomiting (to direct effects on the Central Nervous System in the vomiting centers) , malaise, headache, constriction of peripheral vessels and more severe effects such as ischemia of the extremities.
Ergotamine poisoning is called ergotism.
Ergotamine should not be used in patients with peripheral arterial or venous vascular insufficiency, ischemic heart disease, cerebrovascular disease, systemic infection and hypertension without effective control.
What would contraindicate the administration of scheduled immunizations at a client visit for a 6-month-old infant?
Answer:
Previous anaphylaxis reaction to a previously administered vaccine
Current illness
Immune deficiency
The administration of vaccines may be contraindicated for a 6-month-old infant if they are experiencing a moderate to severe illness, have known allergies to vaccine components, have had previous adverse reactions to vaccines, or have an immune-compromising condition.
There are several factors that may contraindicate the administration of scheduled immunizations to a 6-month-old infant. Generally, vaccinations should not be given if an infant is experiencing a moderate to severe illness with or without a fever, as this may impact the efficacy of the vaccine or exacerbate the existing illness.
Vaccines might also contain immunogens that could provoke severe allergic reactions in some children, especially those with a known allergy to any vaccine component or a history of anaphylactic reactions. Other contraindications include an adverse reaction to a previous dose of the same vaccine or a medical condition that compromises the immune system, making a vaccine potentially dangerous or ineffective.
It's important to closely follow the vaccination schedules recommended by health organizations, such as the US Centers for Disease Control and Prevention (CDC), which provides guidance on the appropriate ages and circumstances under which vaccines should be administered to infants and children.
These schedules are in place to protect children like Olivia, who, at one year of age, would no longer have maternal antibodies to protect against diseases such as meningococcal meningitis—which can be effectively prevented with early vaccination.
Lastly, for individuals with concerns about conditions such as Reye's syndrome related to aspirin allergy, it's essential to discuss potential risks with healthcare providers before proceeding with immunizations to ensure the safety of the child.
A certain type of recurring, often one-sided headache, which is often accompanied by nausea and/or vomiting and extreme sensitivity to light, is called _________
Answer:
Migraine
Explanation:
Migraine is a disabling, biologically based headache that affects genetically predisposed people. This type of primary headache can occur at any age, but it usually manifests more in adolescents, young adults, and affects women more than men.
In about 15% of cases, pain is preceded (or accompanied by) a premonitory aura involving visual symptoms. Its main feature is blurred vision or the presence of bright, zigzag or dark spots in the periods preceding the painful crises.
Typical symptoms are:
Throbbing and pulsating pain, usually unilateral, of moderate or severe intensity; Nausea; Vomiting; Hypersensitivity to light (photophobia), sounds (phonophobia) and certain odors (osmophobia), which last for four to 72 hours and worsen with movement; Irritability; Depression; AgitationFolate is a nutrient recommended especially toFolate is a nutrient recommended especially to ________ in order to ________.
Answer:
Pregnant women and women planning to become pregnant
Explanation:
Folate (Vitamin B) is one of the B vitamin and it is very important as it helps in the synthesizing of DNA and other genetic materials.
It also helps in cell division.
Normally, the human body gets the required amount of folate from normal daily nutrition, but, pregnant women or women seeking to get pregnant are usually prescribed folate supplements as it helps in preventing birth defects in fetus most especially Neural Tube Defects (NTDs) including spina bifida, anencephaly, heart defects. According to researchers, folate can help prevent these defects by more than 70%.
Which of the following statements about public health in the 21st century is true? Group of answer choices
The greatest challenge is how to change human behavior to promote health
The prevalence of obesity is expected to decline because of healthier diets
Violence and drug use are expected to decline because of stricter law enforcement It is expected that more people will become physically active
Answer:
The greatest challenge is how to change human behavior to promote health.
Explanation:
With the invention of new technologies that made our lives easier and simpler, we have become lazier and have changed their diets, replacing healthy food for quick and not nourishing meals. We dedicate more time to other activities where minimal movement is required. These habits have been forming since the last century along with new technologies and the changes in lifestyle. One of the greatest challenges is to change this unhealthy behavior and replace it for healthy habits throughout different plans, campaigns, and education.
Although the fertility rate for women in the United States has declined in recent years to a value below replacement level, the United States population is still increasing because of lower average age at first marriage
A lower infant death rates
B increased longevity
C improved health care
D immigration E Submit
Answer:
B) Increased longevity
Explanation:
Couples getting married earlier in their lives will always result in a longer time in which they could have a kid. Being married and trying for kids longer gives more of a chance to have one and over that extended period of time all it takes is the right circumstances and any non-infertile couple could get pregnant. People also live longer today than they did years ago which would also be grounds for increased longevity.

Olivia, a 9-year-old girl, has no record of ever receiving an influenza vaccination. She has a fear of needles. The only medication she receives on a regular basis is albuterol. Which of the following would be an appropriate recommendation for an influenza vaccination for Olivia?A) Do not administer any influenza vaccine.
B) Recommend one dose of IIV.
C) Recommend one dose of LAIV
D) Recommend two doses of IIV separated by 4 weeks.
Olivia should receive one dose of LAIV, a nasal spray influenza vaccine, which is suitable for children who fear needles, but should consult her healthcare provider first because of her albuterol use.
The appropriate recommendation for an influenza vaccination for Olivia, a 9-year-old girl with a history of albuterol use and no record of influenza vaccination, would be C) Recommend one dose of LAIV (Live Attenuated Influenza Vaccine). LAIV is administered as a nasal spray and can be preferable for individuals who have a fear of needles. It is important to note that the LAIV mimics the normal route of infection without causing the disease and is currently administered in the United States. Given that Olivia is within the recommended age range for LAIV, she can benefit from this type of vaccine. Moreover, Olivia may have asthma given her use of albuterol, in which case LAIV is generally not recommended due to safety concerns, so it would be necessary to consult her healthcare provider before vaccination.

When baroreceptors sense a drop in blood pressure, the vasomotor center responds by __________.
Answer:
Sympathetic stimulation of the heart and vascular system.
Explanation:
Baroreceptors are the type of the mechanoreceptors that are mainly located in the aortic arch and the carotid sinus. They are mainly activated by the change in the blood pressure.
The centers of the brainstem integrate the feedback mechanism in the form of the baroreceptors. This regulate the cardiac functioning of the body and the maintenance of the blood pressure. The vasomotor control center responds to the sympathetic stimulation of the vascular system and the heart.
Thus, the answer is sympathetic stimulation of the heart and vascular system.
Answer:
the vasomotor center responds by triggering peripheral vasoconstriction.
Explanation:
Peripheral vasoconstriction occurs to allow the body to retain core heat for longer as protection against hypothermia by allowing the skin to act as an insulating layer between core organs and the water.
Carol has terminal cancer. She has read that eating certain foods has been found to prolong a person's life. Therefore she spends a great deal of time preparing meals for herself. She was given six months to live but has now exceeded that time. She owes it to her diet and perseverance. What can we expect of Carol's demeanor?
Answer:
She will most likely be more alert and cheerful.
Explanation:
Of course, the fact that Carol has exceeded her life expectancy should make her happy, but no cure for cancer is miraculous, so she should be alert. But above all, positivism is a good way to deal with this disease, since being optimistic the patient improves his temperance to face the disease.
Carol's demeanor might be optimistic as she finds meaning and a sense of control through her precise dietary choices, similar to how Randy Pausch lived his final days with purpose and joy. Diet can influence health outcomes, which may explain her extended lifespan beyond the prognosis, but her emotional resilience and support system are also impactful.
Explanation:Given Carol's situation where she has terminal cancer and has surpassed the life expectancy given to her, it is likely that her demeanor would be influenced by her proactive approach to health through diet and her perseverance. These actions may have provided her with a sense of control and hope, possibly contributing to an optimistic outlook despite her circumstances. This is akin to the case of Randy Pausch, who chose to live his final days with joy and purpose. Carol may be experiencing a similar phenomenon, finding solace and meaning in her actions and possibly reaching a state of acceptance of her condition while still striving to live fully. The impact of diet is indeed significant; studies have indicated that certain dietary changes can influence health outcomes, including reducing tumor growth and extending lifespan in animals. This could partially explain Carol's exceeded life expectancy beyond the initial prognosis. However, Carol's outlook on life, her mental and emotional resilience, and the social support she receives are also crucial components that can affect her demeanor and overall wellbeing.
The _____ returns filtered blood to the bloodstream after passing through the glomerulus.
A. renal pelvis
B. renal vein
C. renal tubule
D. renal artery
Final answer:
The renal vein (option B) returns filtered blood to the bloodstream after it has passed through the glomerulus. This is part of the kidney's function to filter blood, where the renal artery brings in the blood, the nephrons filter it, and then the renal vein carries the purified blood back into circulation.
Explanation:
The structure that returns filtered blood to the bloodstream after passing through the glomerulus is the renal vein. Blood enters the kidney through the renal artery and moves into the glomerulus where filtration occurs. The filtered substances then pass to the renal tubule for reabsorption and secretion processes. Finally, the cleaned and processed blood is returned to the circulation via the renal vein, completing the filtration cycle.
The loop of Henle is part of the:
B. renal tubule

How do the kidneys compensate for acid-base imbalances?
by excreting bicarbonate ion by excreting H+
by reabsorbing bicarbonate ion
by reabsorbing H+ all of the above
Answer:
All of the above
Explanation:
The kidneys are slower to compensate, but renal physiology has several powerful mechanisms to control pH by the excretion of excess acid or base. In response to acidosis, the tubular cells reabsorb more bicarbonate from the tubular fluid, and the collecting duct cells secrete more hydrogen and generate more bicarbonate, and ammoniagenesis leads to an increase of the NH3 buffer. In its responses to alkalosis, the kidneys may excrete more bicarbonate by decreasing hydrogen ion secretion from the tubular epithelial cells, and lower the rates of glutamine metabolism and ammonium excretion.
The kidneys have two very important roles in maintaining the acid–base balance:
They reabsorb bicarbonate from urine.
They excrete hydrogen ions into urine.

Some types of vitamin A are immediately usable by the body, while other types need to be converted first.
Answer:
True: Retinol is the most absorbed.
Explanation:
Vitamin A digestion follows the same process as the rest of the food lipids. Thus, retinol esters are hydrolyzed by pancreatic lipases, after binding to bile salts and micelle formation, and free retinol is absorbed in the duodenum and jejunum. The absorption of retinoids is 80-90% while that of carotenes is 30-40%.
Answer:
Retinol is the most usable form of preformed vitamin A.
Explanation:
reformed vitamin A is only found in animal food sources, foods that are fortified, or supplements.

Unless each step in the conflict resolution process is followed precisely, a conflict cannot be resolved.
True
False
Answer:
true but not always the conflict resolution works every time sometimes the conflict resolution will not solve the problem other methods can solve the problem so it's a maybe
The given statement Unless each step in the conflict resolution process is followed precisely, a conflict cannot be resolved is False .
While following a conflict resolution process can be helpful, it is not necessarily true that each step must be followed precisely for a conflict to be resolved. Conflict resolution is a dynamic and complex process that can vary depending on the nature of the conflict, the individuals involved, and the specific circumstances.
Different conflicts may require different approaches and strategies. It is important to adapt the conflict resolution process to the specific situation and to be flexible in finding solutions that work for all parties involved.
While having a structured process can provide guidance and promote effective resolution, it is not a guarantee that following each step precisely will automatically lead to resolution. Factors such as communication, understanding, empathy, and willingness to find common ground also play significant roles in resolving conflicts successfully.

To treat a severe or minor wound, apply direct pressure with a bandage or a clean towel.
A. True
B. False
Answer:True
Explanation:
While this is wholly true for severe wound, it could be done for minor wounds too especially when they continue to bleed (minor wounds are expected to stop bleeding on their own within a few minutes). After the stoppage of the bleeding, the pressure can be sustained by binding the wound with a bandage. The wound can also be cleaned and rinsed with clean water or normal saline
It’s good to note that the bandage that should be used must be sterile to prevent wound infection and the part of the body involved could also be elevated afterwards especially if it’s a limb.
Answer:
True
Explanation:
Severe wound is when there is significant bleeding and broken bone can also be involved.

The most dangerous route of drug administration is ________________ injection.
Answer:
Intravenous injection (IV)
Explanation:
Injectable medication administration should be performed efficiently, safely and responsibly, in order to achieve the goals of the implemented therapy. Most drugs can be administered by a variety of routes. The choice of the appropriate route in a given situation depends on both the drug and patient-related factors.
Intravenous (IV): should be administered slowly for several hours into one of the superficial veins and with monitoring of the patient's reactions. The drug reaches the bloodstream directly and the effects are produced immediately. Once a drug is injected, there is no way to withdraw it. It is the most dangerous route and vital organs such as the heart, brain, etc., are exposed to high concentrations of the drug.
