CORONARY CIRCULATION: Bill had severe chest pains while watching TV and he broke into a sweat. Fortunately, he was brought to the emergency room. Following an angiogram, it was decided that he would need by pass- surgery. First , they operated on his legs and eventually he had a quadruple coronary by-pass surgery . Explain the chest pains and unusual sweating. What is an angiogram ? how is it done? In this case, what did the angiogram reveal? What is the DIAGNOSIS? Why did the surgical team operated on his legs first? What is coronary by-pass surgery? What is a quadruple by-pass surgery? How is done and what is needed? Following the surgery, Bill was put on a fat controlled and salt controlled diet. Explain the benefit of both diet restriction. Explain why he must follow an exercise regime .Why should that exercise program be a MODERATE one He may be required to take an aspirin a day. Explain the specific benefit of this recommendation.

A. Explain the chest pains and unusual sweating. - Chest pains also known as angina pectoris is a common symptom of coronary artery disease. This type of heart disease can lead to a heart attack or myocardial infarction. The unusual sweating is because stress stimulates the sympathetic nervous system causing the adrenal glands to release epinephrine or adrenaline which causes constriction of the blood vessels in the heart and excess sweating. B. What is an angiogram ? how is it done? In this case, what did the angiogram reveal? What is the DIAGNOSIS? - Angiogram is a special test or x-ray done after injecting a dye in a blood vessel and checking for blockage or aneurysm. The diagnosis of an angiogram would be an embolism or an aneurysm. C. Why did the surgical team operated on his legs first? - Located in the legs are the great saphenous veins which are the most common blood vessels used in coronary bypass surgery due to their length and less need for blood vessels in the leg than in the heart. D. What is coronary by-pass surgery? What is a quadruple by-pass surgery? How is done and what is needed? - Coronary bypass surgery is used to detour blood on the surface of the heart usually to prevent myocardial infarction (MI) or help after you have MI. Quadruple bypass is when 4 different coronary arteries are detoured. In traditional coronary bypass there is general anesthesia, rib cage is cracked open, and heart and lungs machine to keep it functional. Leg surgery is done to get access to the veins. Risks include heavy bleeding, infection, scarring, and lung therapy. E. Following the surgery, Bill was put on a fat controlled and salt controlled diet. Explain the benefit of both diet restriction. - Fat can build up in the coronary arteries leading to a blockage eventually atherosclerosis. Salt will increase your water retention which lowers the water concentration in the blood making blood thicker and making it harder for blood to pass through the blood vessels. F. Explain why he must follow an exercise regime .Why should that exercise program be a MODERATE one - Exercise causes increase contractions of the skeletal muscles and diaphragm, squeezing the veins and increasing blood flow to the heart. It should only be moderate exercise so you don't overwork the heart and the blood vessels. G. He may be required to take an aspirin a day. Explain the specific benefit of this recommendation. - Aspirin is blood thinner than prevents clotting making it easier to flow through the blood vessels.

The sinoatrial node is made of autorhythmic cells. What does that mean? Describe the contraction signal timing as it passes through the conduction system of the heart. How is that timing important for the pumping action of the heart?

Auto rhythmic cells are self-excitatory and have the ability to spontaneously depolarize. The cardiac conduction system is a pathway of cardiac muscle fibers in which electrical impulses travel along the heart. Electrical impules in the heart travel from the sinoatrial node (SA) and spread to both atria. When the action potential reaches the AV node, it slows down allowing time for both atria to completely contract and empty into the ventricles. It is important that this happens so that the ventricles can pump out the most blood possible during systole.

This is an organelle that modifies proteins produced elsewhere.

Mrs.J. delivers her first child 8 weeks premature. The physician notices that the infant's inhalation are long and forced, and the infant seems to tire rapidly. What do you think the physician will recommend? Why?

At 28 weeks the baby produces surfactants so if it does not produce surfactant then it prevents the wall for the alveoli from separating. Surfactant prevents the walls of the alveoli from sticking together, which would cause forced exhalation. The surfactants are made from Type 2 alveolar cells. The physician would recommend supplemental O2 and surfactant therapy.

Blood vessels enter through the periosteum into a perforating canal. The vessel may follow along the axis of the bone through a central canal. Osteocytes have long, almost dendritic-like extensions or arms that reach out through tiny holes called canaliculi. The canaliculi connect one cell to another and to the central canal. Oxygen would leave the blood vessel in the central canal and travel through the canaliculi from cell to cell until it reaches the cell in question.

The episode passes, but when the infant is bathed (warm water) she becomes cyanotic again. Blood gas levels are taken and they show the arterial blood is only 60% saturated. Physical examination indicates that there are no structural deformities involving the respiratory or digestive systems. ECHOCARDIOGRAPHY shows a heart defect. What is the specific causes of the problem?

Cyanosis is lack of O2 in the cells and tissues. When the temperature increases, the blood veeseel dilates and then you can see the blue color more. When less O2 goes to the baby the valves do not open and close properly. This is a congenital heart dieaes where not enough O2 goes to the rest of the body.

Jonathan a young college student was determined to get in shape fast for summer. He participated in many classes and lifting as heavy as he could. But after a major workout using the HIT plan, for High Intensity Interval training, he experienced major pain in the back of his left leg, The swelling was huge and the pain extreme. Later on he noticed his urine was a much darker color than normal. He went to see his physician. After tests, It turned out that he had overexerted his muscles and in this case had torn his gastrocnemius. This is an example of rhabdomyolysis. Urine tests were ordered and they confirm rhabdomyolysis. Jonathan was told the muscle will heal and some repair will occur .But the prognosis is : muscle will not return to its initial perfect state. Explain the urine test, the healing, the repair and the prognosis

Due to the myoglobin (the protein found in the urine) Muscle cells would not full repair the muscle instead it will be replaced with the collagen tissue (scar tissue/satellite cells) to repair

Carly was playing tennis and fell. She hurt her right knee. Her bruises were very apparent although apparently not too serious. A few days later, her friends were shocked and saddened to learn that Carly died of a " Pulmonary embolism". What is an embolism? What is a pulmonary embolism? Why is a pulmonary embolism more common than a cerebral embolism as a result of leg injury?

Embolism is blockage of an artery by a clot. This embolism originated from the veins of her right knee when she hurt it during tennis. Once it reached her pulmonary arteries it prevented deoxygenated blood from reaching the lungs and becoming deoxygenated. Pulmonary embolism is more common as a result of a leg injury because the embolism would have traveled through the pulmonary circuit before traveling back to systemic circuit.

Emily, a 64 year old obese woman, was brought to the hospital suffering pain in her legs and an X-ray revealed that she had a simple fracture in her right femur and a crack in her left tibia. Other tests revealed that her bones were brittle and porous. What might have happened to Emily and what advise would she have been given by her physicians.?

Emily is an unhealthy individual who has developed postmenopausal osteoporosis due to the lack of estrogen (anabolic steroid) in her body. Estrogen is an anabolic steroid that promotes bone growth, maintains Ca deposition in bone, and helps keep bone hard in adulthood. Her physicians would give her vitamin d supplements and recommend more calcium in her diet and weight bearing exercises. Vitamin D promotes Ca and P absorption from the small intestine and bone mineralization. Deficiency in Vitamin D leads to decreased collagen production which slows down bone growth and delays repair of broken bones. Collagen is a molecule that forms a triple helix that is very strong and keeps bone very strong, lacking it makes one brittle and easily broken (she overall needs to lose weight because her bones are too brittle and can't support her body weight)

Alicia , 15 years old , following a CT scan of her right thigh, was just diagnosed with osteogenic sarcoma, a form of bone cancer. She will need surgery to remove the tumor. Prior to the surgery, she will undergo chemotherapy to shrink the tumor. If the surgeon is unable to remove the whole tumor, she will undergo radiation therapy. Explain why her tumor is called sarcoma. Why will she need surgery? How is chemotherapy different from radiation therapy?

Her tumor is called a sarcoma because it destroys normal bone tissue. She needs surgery due to the possibility of spreading through to the body. Chemotherapy involved the administration of drugs that cause death to cancerous cells where as radiation therapy breaks down chromosomes blocking cell division

How is the beginning of intramembraneous ossification different from endochondral ossification?

Intramembraneous ossification starts in connective tissue from mesenchymal cells that become osteoblasts. These osteoblasts cluster together into an ossification center. Endochondral ossification starts with a hyaline cartilage "template." Mesenchymal cells become osteoblasts and begin forming bone around the cartilage.

Marty, an apparently healthy 35 year old male, just moved from the New Jersey Shore to Aspen ,Colorado . He is having a hard time adjusting to living at high altitude. He feels unusually tired all the time and has been also experiencing difficulty breathing. Following tests including spirometry , he was told that his lungs were functioning well but that his new environment was the cause of his symptoms. His physician reassured him that eventually these symptoms would subside and that his body would adapt. Upon the diagnosis, his daughter Rachelle, an aspiring nurse, explained to him that she had learned in her A & P class that hypoxia could lead to hypoxemia and eventually to ischemia which explains his symptoms. The adaptation the physician mentioned would be due to his bone marrow providing more red blood cells and that will help him eventually. Explain the symptoms, the tests, the causes and adaptation.

Hypoxia: low O2 in environment Hypoxemia: low O2 in blood Ischemia: not enough O2 going to tissues Spirometry: measure our capacity of lungs; how much you breath out At high altitude, there is less atmospheric pressure of O2, so harder to get air into your lungs Low O2: Chemoreceptors detect that in Medulla and stimulate bone to produce more Red BC

Evelyn arrived to hospital with a several symptoms. She complained of weakness in her muscles including her arm muscles, difficulty breathing at times, and flabby or laxed orbicularis occuli . The doctor ordered an EMG as well as blood tests.. 4.Upon confirmation, among other things, Evelyn was prescribed Corticosteroids to be followed later with Methotrexate.

Initial treatment of the corticosteroids can be used not only help reduce the inflammation but it can stop White Blood Cells from producing antibodies to attack the acetylcholine receptors. The reason for changing her initial treatment of corticosteroids to methotrexate because it is highly discouraged to use corticosteroids the for a prolonged period of time. Prolonged use will lead to significant bone resorption which can cause bone weakness, fractures, etc.

Integumentary System

Stacey has been diagnosed with a form of anemia due to vitamin B12 deficiency. Apparently she cannot absorb the vitamin from the food she eats. Her physician recommended periodic intramuscular injections of the vitamin. Stacey knows that you are taking A & P and would like to know the difference between Intramuscular as opposed to subcutaneous injections. She asked you to indicate and explain where she may receive the injections and why those particular sites would be preferred.

Intramuscular injection penetrates the skin and subcutaneous layer to enter the muscle itself . - Common sites for this injection type include the gluteus medium muscle or the buttock, lateral side of thigh in the middle portion of the vastus laterals muscle, or deltoid muscle of the shoulder because areas of these muscles are thick and absorption is promoted by their extensive blood supply. Subcutaneous injections are administered as a bolus into the subcutis - Abdomen: at or under the level of the belly button, about two inches away from the navel. Arm: back or side of the upper arm

Usually for large doses or chronic or long term situations they use intramuscular injections, meaning they inject the drug within a large and vascular muscle such as Gluteus Medius and not directly into the Blood stream or a vein . 2. Why would they select the Gluteus Medius over the Gluteus Maximus for such injection?

Intramuscular injections are given deep within the muscle of the gluteus medius to avoid injury as it is away from major nerves (i.e. Sciatic nerve) and blood vessels.

This is a negatively charged atom.

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent succinylcholine to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent such as succinylcholine would interfere with muscle contraction

Muscle contraction begins with a stimulus to the nerve, when the impulse reaches the neuromuscular jxn depolarization occurs resulting of an influx of calcium ions which then release a neurotransmitter AcH into the cleft. The AcH combines with receptor sites on the post junctional muscle cell membrane, depolarizes, and then facilities the entry of sodium. Neuromuscular blocking agents act at the motor end plate by competing w/ AcH for the receptor sites, or by blocking depolarization.

Alice and James adopted a 3-year old child from a Third World Country. They notice that her legs were bowed and there were some deformities in her cranial and pelvis bones. They brought her to a physician for a diagnosis. What was the diagnosis and what was the treatment for the disorder?

The 3 year old child has rickets which is a form of dwarfism osteoporosis caused from inadequate calcification of the extracellular bone matrix, usually caused bv vitamin d deficiency. Growing bones become "soft" or rubbery are are easily deformed. Because new bone formed at the epiphyseal plate fails to ossify, bowed legs and deformities of the skull, rib cage, and pelvis occur. Treatments for rickets is Vitamin D supplements and administration of T4 (Thyroxine). Vitamin D promotes Ca and P absorption from the small intestine and bone mineralization. T4 is a hormone produced by thyroid gland which controls basic metabolism before and after brith. Bone growth will be fixed with the administration of this hormone

Veronica is a 50 year old woman went to see her physician . She complained of shortness of breath and intermittent fainting spells. Her doctor runs various tests and finds that the AV node is not functioning properly. How is that finding related to her symptoms ? What is the suggested treatment?

The AV node is located in the intertribal septum just anterior to the opening of the coronary sinus, If AV node not working properly this means VENTRICLES do not have ENOUGH time to fill up with blood therefore NOT enough blood for RIGH VENTRICLE goes to LUNGS to pick up oxygen and not enough oxygen blood from LEFT ventricle goes to the REST of body - Consequences , faster and shorter breathing rate to get more Oxygen, Diaphragm ( a muscle) also not very powerful may even be ischemic to get more air etc, Even the MYOCARDIUM is weaker , not just pumping less blood , but less force too ( again ischemia) All cells are getting LESS and LESS oxygen but the BRAIN is in a worse situation and that explains the CEREBRAL CORTEX shutting down.. Remember SHE IS NOT DEAD ,so other brain regions ( PONS, MEDULLA) although oxygen poor are still working treatment = The suggested treatment is surgery to implant an artificial pacemaker.

Regina is taking a class in First Aid. She is learning CPR or Cardio Pulmonary Resuscitation. She is instructed on how to place her hands on the STERNUM, to press more in the center , closer to the manubrium. Based on what you have learned in lab, why is it BEST to place the hands more in the center and NOT on the lowest portion of the sternum? explain the potential problems if instruction not followed - what may happen if Regina puts pressure on the BOTTOM instead?

The best place to have the hands more towards the center and not the lowest portion of the sternum is because you will not only break/fracture the xiphoid process to the point where you are driving it into the internal organs, such as the diaphragm and liver. The reason as to why the xiphoid process can break is because it is an unsupported structure and can break off under pressure.

Ghis has been suffering from a "bad knee" for several months. She is a tennis player who often slides in to attack a ball; she is an aerobic devotee and a jogger. She visited an orthopedic surgeon last week who told her that he would "like to have a look at her knee joint". He also told her that her symptoms indicated damage to the meniscus and it might have to be removed. What will the doctor do to see the joint and if the meniscus is removed will Ghis be able to play tennis again? If yes, how soon?

The doctor will preform a minimal invasive procedure called arthroscopy which involved the examination of the interior joint with an arthroscope. Yes she will be able to play again after six weeks because that is when re-establishment of synovial fluid occurs

Lynn is a woman who lives in Wayne NJ. One Saturday, a nice sunny day , for some fun exercise, she ventured with her son into the woods behind her house. A few days later, she complained of joint pain, flu-like symptoms with fever, and difficulty thinking.

The doctor would look for the "bull's eye" mark on the patient's skin.

A Doppler ultrasound was performed on an infant who had symptoms of breathlessness and it was found that he had a patent ductus arteriosus. Discuss the location and function of the ductus arteriosus in the fetus and relate it to the reason for the infant's breathlessness.

The ductus arteriosus is a shunt between the pulmonary trunk and the aorta in the fetus, which normally closes at birth. Breathlessness is due to the mixing of oxygenated and deoxygenated blood because the connection between the aorta and the pulmonary trunk remains slightly open

A 35 year old woman went for check up due to multiple fractures in recent months. Since she had not gone through menopause at this age, her condition was puzzling. Several Blood tests were done as well as a bone densitometry. The TESTS results SO FAR are as follow: Bone Density results: osteoporosis of the right hip Blood Ca Normal, within 9-11 mg% Vitamin D levels normal Estrogen levels Normal Cortisol levels normal The only test results still missing is about PTH level 1. Based on the results so far, indicate what the expected result for PTH is and explain why

The expected result for the PTH would be abnormally high, because their may be a parathyroid tumor

The muscle has two, three, or four origins, respectively.

If your doctor notices a marked decrease in calcium ion levels in your blood, what gland might he suspect is not functioning properly and why?

The parathyroid gland normally responds to low calcium ion levels in the blood and releases PTH which mobilizes osteoclasts to step up bone destruction, releasing more calcium into the bloodstream. If the parathyroid is not functioning properly it may release too much PTH or not respond at all, which seems to be the case here.

Most muscles contain ________.

a mixture of fiber types

Bill broke his leg in a football game and after 6 weeks in a cast, the cast is finally removed. As he steps down from the table after the cast is removed, he loses his balance and falls. What was the purpose of the Cast? Explain why Bill fell.

The purpose of the cast was to let the bone fracture repair which occurs in four phases. The four phases are called Reactive phase, Fibrocartilaginous callus formation, bony callus formation and bone remodeling phase. The purpose of treatments for fractures like the cast was to realign bone fragments, immobilize to maintain realignment, and restore function (process called reduction). Bill fell because the strength of the unstressed bones diminishes due to the loss of bone minerals and decreased number of collagen

Sharon replies "This is the first time I have ever had a head injury from a bike. I don't think I need a helmet". Based on your understanding of the skull, how should the nurse respond to Sharon?

The skull is the frame work of the head. The cranial bones form the cranial cavity which encloses and protects the brain. The skull protects a vital organs such as the brain and intramembranous membrane . Skull bones are thin and should be protect in order to avoid injuries to the brain which plays a vital role in many of the functions of your body. These bones are made through ossification. If there is an injury to the skull the brain will be effected and there will not be room for the brain to swell up and cause no injury

Usually for large doses or chronic or long term situations they use intramuscular injections, meaning they inject the drug within a large and vascular muscle such as Gluteus Medius and not directly into the Blood stream or a vein . 1.Why would they inject some drugs into a large muscle and not into the Blood stream directly?

They would inject some drugs into a large muscle and not into the blood stream directly because the particular medication may irritate the vein or a suitable vein my not be located. With an intramuscular injection you can put the medicine deep into the muscle tissue, allowing it to be quickly absorbed into the bloodstream.

Forrester , a 65 years old man has long suffered for arthritis . His hip joints are severely damaged and he has been told that he has to undergo total arthroplasty. What is this procedure? Describe how is it done? What would be the potential benefits of his surgery?

Total arthroplasty is the replacement of joints that have been severely damaged with prosthesis. The damaged portions of the acetabulum and the head of the femur are replaced by prostheses The acetabulum is shaped to accept the new socket, the head of the femur is removed, and the center of the femur is shaped to fit the femoral component. once the appropriate acetabular and femoral components are selected they are attached to the healthy portion of bone with acrylic cement which forms an interlocking mechanical bond.

Angelina was in a car accident. She had multiple injuries on her right thigh or leg above the Knee. She suffered 1. Muscle lacerations in that leg 2. Damage of the blood vessels serving that leg 3.

Didi just had a bone density test done and she was told diagnosed with early signs of osteoporosis in her right hip. In addition to other things, her physician instructed her to do weight baring exercises Her doctor recommended weight bearing exercises . What is the concept behind this recommendation? ( why this type of exercise) Explain

Weight baring exercises are recommended because like muscle bone is a living tissue, and it stimulates the cells (osteoblasts) to prevent the constant degradation of bone (osteoclasts). Weight-bearing exercise also puts more tension on your muscles, and it puts more pressure on your bones, which then respond by continuously creating fresh, new bone.

Walking is an example of this type of exercise
