someone please please help me...?1. Jamie has the flu. She is uncomfortable and reaches out for flu medication, which is supposed to make her more comfortable. But her sister who is taking a course in Anatomy and Physiology informs her that having a fever might actually be beneficial. Pick the statement that is incorrect regarding the benefits of fever: (immunity)
(a)Fever can retard (slow down) the multiplication of certain pathogens
(b)Fever increases the metabolic rate of the body thereby encouraging immune reactions
(c)Fever slows down the action of interferons
(d)Fever can help promote tissue repair by retarding the physical activities of the host
2. Little Joseph is bitten by a stray dog and he is rushed to the ER. The attending physician gives him an antiserum with anti-rabies antibodies. Joseph is provided with _________ type of immunity: (immunity)
(a)naturally acquired active immunity
(b)naturally acquired passive immunity
(c)artificially acquired active immunity
(d)artificially acquired passive immunity
3. Oneka's village has been struck by famine and like many other children of her village, she too shows signs of starvation (her arms and legs are really frail and her abdomen is swollen). All of the following statements correctly describe the physiological basis of her condition EXCEPT: (blood)
(a)Hypoproteinemia has caused water to leave her blood vessels by osmosis
(b)Lowered levels of albumin in her plasma have contributed greatly to lower than normal blood osmolarity.
(c)Lowered levels of fibrinogen in her plasma have contributed greatly to lower than normal blood osmolarity.
(d)Low protein intake has led to reduced synthesis of albumin resulting in lowered blood osmolarity
4. If the oxygen level in the blood is 100 mmHg and the oxygen level in the alveoli is 140 mmHg: (Respiration)
(a)oxygen moves by simple diffusion from the alveoli into the blood
(b)oxygen moves by simple diffusion from the blood into the alveoli
(c)oxygen moves by active transport from the alveoli into the blood
(d)oxygen moves by active transport from the blood into the alveoli
5. A recent news item reported a nurse who was suspected of killing his patients using an overdose of vecuronium, which is a skeletal muscle relaxant normally used in limited quantities during surgery. The victims stopped breathing and died quietly in their sleep because vecuronium causes: (Respiration)
(a)massive vasodilation, leading to circulatory shock
(b)relaxation of the heart muscle, leading to death
(c)relaxation of the diaphragm, which makes inhalation impossible
(d)constriction of the bronchioles thereby cutting off air supply to the lungs
6. Susan is an obese patient who has recently had a partial gastrectomy. She must be given Vitamin B12 injections in order to prevent pernicious anemia because: (Digestive system)
1.vitamin B12 is necessary for the formation of hemoglobin
2.intrinsic factor produced by the stomach is necessary for the absorption of Vitamin B12
3.an oral administration of Vitamin B12 might be ineffective in this case
4.The stomach is stimulated to produce above normal levels of intrinsic factor
7. Mr. Ray has been diagnosed with atherosclerosis (the formation of plaque and subsequent hardening of the arteries) of the carotid artery. His cardiologist suggests stenting of the carotid artery. The advantage of stenting directly impacts the relationship between: (blood vessels)
(a) blood flow and blood pressure
(b) blood flow and vessel length
(c) blood flow and viscosity
(d) blood flow and vessel radius
8. Jacqui finally quit smoking, but the damage done over the years has resulted in her having to go to the hospital for sever pneumonia on a recurring basis. The pneumonia is bad enough because it makes it harder to breathe, but sometimes it gets so bad that it actually causes her blood pH to shift. Then she has: (Acid base balance)
(a)metabolic alkalosis
(b)metabolic acidosis
(c)respiratory acidosis
(d)respiratory alkalosis
9. Michael has severe pernicious anemia. He frequently resists taking his vitamin B12 shots and ends up in the hospital complaining of shortness of breath. In order to compensate for the lack of RBCs (and therefore O2 carrying capacity) he ends up breathing more deeply and rapidly. Unfortunately, this sometimes leads to a change in his plasma pH. If so, he has: (Acid base balance)
(a)metabolic alkalosis
(b)respiratory acidosis
(c)metabolic acidosis
(d)respiratory alkalosis
10. Baby Carrie is born with an opening called Foramen ovale in the septum or wall between the ventricles. Which of the following is a likely consequence? (Heart)
(a)pumping of blood through the body will be more efficient because pressure from both ventricles will be added together
(b)deoxygenated blood will be sent to the body
(c)hemorrhage due to loss of blood from the hole in the heart
(d)this is normal, there would be no significant consequence

Too much for us to do sunshine! We are able to help people, b ut to ACTUALLY DO your homework, - NOT the intention of this website! But if you study your text book, there should be answers to the questions.
