PHPM 407 507 Health Care Economics and Policy
Medicare was created over the protests of doctors who ultimately have benefited from the increased
health care consumption it fuels.
Undergraduate students should complete the first 4 questions.
1) What sort of market failure existed prior
to 1965 which prevented the free market
for health insurance, from satisfying the
need for the elderly to protect against
the risk of catastrophic health events?
2) Explain how this market failure, would
cause harm to individuals.
3) What government agency or program
exists to try to correct this market
failure?
4) What private sector, industry, or group of
individuals would have a financial
incentive to capture this government
agency?
5) Describe which Hallmarks of Regulatory
Capture you see in this area of health
care. (graduate students only)
1) Prior to 1965, the free market for health insurance failed to adequately address the needs of the elderly in protecting against the risk of catastrophic health events.
2) This market failure caused harm to individuals by exposing them to the risk of incurring exorbitant medical expenses that could potentially deplete their savings or push them into poverty.
3) To address this market failure, the U.S. government established the Medicare program in 1965.
4) In the context of Medicare, the private health insurance industry and healthcare providers have a financial incentive to capture the government agency responsible for administering the program.
5) This dynamic raises concerns about regulatory capture, where private interests can exert undue influence over a government agency meant to serve public interests.
1) Prior to 1965, the free market for health insurance fell short of meeting the needs of the senior population in terms of reducing their chance of experiencing catastrophic medical events. This market failure resulted from a number of issues, including the high costs of geriatric healthcare and the inherent unpredictability and uncertainty of medical expenses as people age.
As a result, obtaining comprehensive health insurance was often difficult or prohibitively expensive for senior people, leaving them at risk of facing severe financial hardship in the case of a serious sickness or accident.
2) Individuals suffered harm as a result of this market failure since it put them at risk of expensive medical bills that would exhaust their resources or force them into poverty. Elderly people faced the possibility of shouldering the full financial burden of catastrophic health events if they did not have access to affordable health insurance options that were tailored to their unique needs. This had negative effects such as inadequate or delayed medical care and higher mortality rates among the elderly population.
3) The Medicare program was developed by the American government in 1965 to solve this market failing. Medicare is a government health insurance program that is primarily intended to cover those over the age of 65 as well as some younger people who have impairments or end-stage renal illness. The government wanted to make sure that seniors had access to inexpensive healthcare and were shielded from the financial risks associated with catastrophic medical events through Medicare.
4) The private health insurance sector and healthcare providers have a financial interest to control the government organization in charge of running Medicare. Healthcare providers have an interest in influencing Medicare reimbursement rates and policies to increase their revenue streams, while the private insurance sector stands to gain by providing supplemental insurance plans that fill in Medicare coverage gaps.
5) The private sector has a financial stake in capturing the Medicare program, including insurance firms and healthcare providers. For their own financial interest, they can sway laws, reimbursement rates, and practices. This situation gives rise to worries about regulatory capture, in which corporate interests can have disproportionate influence over a government agency that is supposed to represent the interests of the public.

a 6 week-old male infant is brought to the nurse practitioner because of vomiting. The mother describes vomiting after feeding and feeling a "knot" in his abdomen especially after he vomits. The child appears adequately nourished. What is the likely etiology?
The likely etiology of the infant's symptoms is pyloric stenosis, characterized by vomiting after feeding and a palpable "knot" in the abdomen.
The likely etiology of the 6-week-old male infant's symptoms is pyloric stenosis. Pyloric stenosis is a condition characterized by the narrowing of the pylorus, the opening between the stomach and the small intestine. It is more common in males and usually presents around 2-8 weeks of age.
The symptoms described by the mother, including vomiting after feeding and a feeling of a "knot" in the abdomen, are classic signs of pyloric stenosis. The narrowing of the pylorus prevents the normal passage of food from the stomach to the intestine, leading to forceful projectile vomiting. The "knot" sensation may be due to the hypertrophied pylorus, which can be palpated as a firm mass in the upper abdomen.
To confirm the diagnosis, the healthcare provider may perform an abdominal ultrasound, which will show the thickened pylorus. Treatment for pyloric stenosis typically involves a surgical procedure called pyloromyotomy to relieve the obstruction.

Flexion of the forearm at the elbow involves the use of the principle of third-class lever. The muscles of the human body move the bones, producing movements such as flexion, extension, and rotation.
The bones act as levers, and the joints function as fulcrums.
The muscles of the human body function like the applied force that pulls the lever, while the weight of the limb represents the resistance or load against which the force is applied.
The levers used in the body are classified as either first-class, second-class, or third-class levers.
The forearm joint (elbow joint) operates as a third-class lever, while the triceps brachii muscle works as the applied force, and the weight of the forearm acts as the resistance.
The elbow joint has a smaller radius than the hand, which means that the force applied by the triceps brachii must be more significant than the weight of the forearm.
Consequently, the elbow joint has mechanical disadvantage, meaning that it requires more force to move than the resistance it carries.

Correctly label the following structures surrounding the testis. Rete testis 0.2 points Body of epididymis Skipped Seminiferous tubule eBook Tail of epididymis Print References Spermatic cord Efferent ductule Blood vessels and nerves Ductus deferens < Prey 7 of 25 Next >
The structures surrounding the testis are: rete testis, body of epididymis, seminiferous tubules, tail of epididymis, spermatic cord, efferent ductules, blood vessels and nerves, and ductus deferens.
The testis is an essential reproductive organ in males, and it is surrounded by several structures that play crucial roles in the production, maturation, and transport of sperm. One of these structures is the rete testis, which is a network of tubules located within the testis. It acts as a collecting system for sperm produced in the seminiferous tubules.
The body of the epididymis is another structure surrounding the testis. It is a tightly coiled tube that sits on the back of the testis. The epididymis functions as a site for sperm maturation and storage.
Seminiferous tubules are found within the testis and are responsible for sperm production through a process called spermatogenesis. These tubules are lined with cells that undergo cell division and differentiation to produce spermatozoa.
The tail of the epididymis is the last part of the epididymis and acts as a storage site for mature sperm before they are transported further.
The spermatic cord is a bundle of structures that includes blood vessels, nerves, and the ductus deferens. It extends from the inguinal canal to the testis and provides the essential blood supply and innervation to the testis and other associated structures.
The efferent ductules connect the rete testis to the epididymis, allowing the transport of sperm from the testis to the epididymis.
Finally, the ductus deferens (also known as the vas deferens) is a muscular tube that transports mature sperm from the epididymis to the urethra during ejaculation.
In summary, the structures surrounding the testis include the rete testis, body of epididymis, seminiferous tubules, tail of epididymis, spermatic cord, efferent ductules, blood vessels and nerves, and ductus deferens. Each structure plays a crucial role in the production, maturation, and transport of sperm.

a) establishing boundaries
b) discussing the role of the nurse
c) beginning the termination process
d) explaining the purpose of the meetings
Establishing boundaries is essential in the nurse-client relationship. Boundaries serve as guidelines or limitations that healthcare professionals and clients establish to differentiate their personal and professional interactions. Clear communication of these boundaries is crucial to ensure that clients understand the limitations and expectations within the relationship.
During the initial meetings, the nurse should explain the purpose of the sessions, which is to establish a plan of care to help the client achieve their goals. The nurse should also clarify their role and responsibilities in the therapeutic relationship. Additionally, the nurse should discuss the time-limited nature of the relationship and initiate the termination process when appropriate, emphasizing that it is a natural progression rather than a personal decision.
Setting boundaries helps prevent clients from becoming overly dependent on the nurse. It is essential to maintain a professional distance to avoid the development of an unhealthy attachment or reliance on the nurse. Nurses should refrain from establishing personal relationships with clients or blurring the lines between their personal and professional lives.
By establishing and maintaining appropriate boundaries, nurses ensure a professional and therapeutic environment that fosters the client's growth and autonomy.

If you're having trouble filling the tube or getting blood flow at all
Ease the needle backward as it might have punctured through the other side of the vein
Gently move the needle forward to clear the lumen
Adjust your angle as the bevel might be against the vein wall
All the above
If you're having trouble filling the tube or getting blood flow at all, all the above steps should be taken. The steps are: Ease the needle backward as it might have punctured through the other side of the vein. Gently move the needle forward to clear the lumen. Adjust your angle as the bevel might be against the vein wall.
Usually, when blood does not come out, a nurse would not know whether it is because of a clot in the vein or the needle being placed wrongly. It is best to ease the needle backward if you are having trouble filling the tube or getting blood flow at all. This is to check if the needle has gone through the other side of the vein. If it is not on the other side of the vein, try to gently move the needle forward to clear the lumen. If you still are not getting any blood flow, adjust the angle as the bevel might be against the vein wall.
It is best to start again if you are still having trouble getting blood flow. The practice of venipuncture must be performed in a specific manner to prevent complications, which can range from mild to severe. Proper blood collection, storage, and analysis are critical components of laboratory operations, and they necessitate the use of skilled personnel and safe techniques. This minimizes the risk of infection, errors in test results, or injuries.

calculate the dosage in milligrams per kilogram body weight for a 175 lb adult who takes two aspirin tablets containing 0.324 g of aspirin each.
Answer:
Therefore, the dosage of aspirin for the 175 lb adult is approximately 8.16 mg per kilogram of body weight.
Explanation:
o calculate the dosage in milligrams per kilogram body weight, we need to convert the weight of the adult from pounds to kilograms.
1 pound is approximately equal to 0.4536 kilograms.
So, the weight of the adult in kilograms would be:
175 lb * 0.4536 kg/lb = 79.378 kg (rounded to three decimal places)
Next, let's calculate the total dosage of aspirin in grams:
2 tablets * 0.324 g/tablet = 0.648 g
Now, we can calculate the dosage in milligrams per kilogram body weight:
Dosage = (0.648 g) / (79.378 kg)
Converting grams to milligrams:
Dosage = (0.648 g) * (1000 mg/g) / (79.378 kg)
Calculating the dosage:
Dosage ≈ 8.16 mg/kg (rounded to two decimal places)
Therefore, the dosage of aspirin for the 175 lb adult is approximately 8.16 mg per kilogram of body weight.

b. Drinking 3 to 5 beers a day
c. Previous peptic ulcer
d. Taking warfarin (Coumadin)
The nurse should consult with the provider if the patient has a (option C) previous peptic ulcer when considering the use of acetaminophen for osteoarthritis.
The correct option in this case is option C: Previous peptic ulcer.
When assessing the patient's health history, the nurse should look for any factors that may increase the risk of adverse effects or interactions with acetaminophen. In this scenario, a previous peptic ulcer is the most concerning finding that would warrant consultation with the healthcare provider.
Acetaminophen is generally considered safe for most individuals when taken at recommended doses. However, it can pose a risk to patients with a history of peptic ulcer due to its potential to cause gastrointestinal irritation and bleeding. The nurse should consult with the provider to discuss alternative pain management options for the patient to avoid exacerbating the peptic ulcer.
The other options (a, b, and d) may also be significant in the patient's health history, but they are not as directly related to the choice of acetaminophen for osteoarthritis. Smoking history (option a) and alcohol consumption (option b) can have various health implications, but they do not specifically affect the choice of acetaminophen. Taking warfarin (option d) would require careful monitoring due to its potential interaction with acetaminophen, but it does not directly necessitate a consultation regarding the choice of medication.
