A patient has had a serious accident and lost a lot of blood. Unfortunately, all that is available is ocean saltwater. In an attempt to replenish body fluids, ocean saltwater (equal to the volume of blood lost) is transferred directly into one of his veins. What will be the most probable result of this transfusion? Hint: Ocean saltwater is saltier than human blood plasma. Group of answer choices The patient's red blood cells will shrivel up because the ocean saltwater is hypertonic compared to the red blood cells. The patient's red blood cells will swell because the ocean saltwater is hypotonic compared to the red blood cells. The patient's red blood cells will shrivel up because the ocean saltwater is hypotonic compared to the red blood cells. It will have a favorable effect as long as the water is free of viruses and bacteria. The patient's red blood cells will swell because the ocean saltwater is hypertonic compared to the red blood cells. Tay-Sachs Disease causes accumulation of lipids in the brain resulting in progressive neurodegeneration and death in early childhood. Individuals with this disorder cannot destroy a type of lipid called glucocerebroside that needs to be eliminated, resulting in its accumulation in the brain and spinal cord. These individuals have a defect in which organelle that breaks down different types of molecules? Group of answer choices mitochondria chloroplasts Golgi apparatus ribosomes lysosomes

Step 1
The most probable result of the transfusion of ocean saltwater into the patient's veins will be that the patient's red blood cells will shrivel up because the ocean saltwater is hypertonic compared to the red blood cells. Show more…

Ed Rivers, a 3rd-year medical student, was alone in the hospital ER one night. It was unusually quiet that night, and the resident was getting some much-needed sleep. A patient, Mrs. X, was brought in showing signs of serious dehydration. Ed tried to give her water, but she vomited it back up. Feeling he must try something, and not wanting to wake the resident, Ed administered 1 liter of sterile distilled water IV. Assume for simplicity that the red blood cells contain only solutes to which the RBC membrane is impermeable, and that the RBCs and plasma are in osmotic equilibrium when the patient is brought in. The osmolarity of the RBC is 300 mOsm/L.

1. A young man in his 20s has a heart attack and is rushed to the hospital. Blood is drawn, and his cholesterol level is tested and found to be very high. The doctor tells him he has a genetic condition in which he is unable to effectively remove LDL particles containing cholesterol from his blood and into his cells. Which cellular (membrane transport) process is not functioning normally? Be specific. 2. The liver produces a protein called albumin. The major function of albumin is to exert osmotic pressure to pull fluid back into the blood on the venule end of the capillary bed – the side that takes away some wastes and deoxygenated blood carried in the fluids after the oxygen and nutrients have been used by the cells of the tissue. a).Predict what happens to osmotic pressure in a patient who has cirrhosis of the liver and is not producing adequate levels of albumin. Does osmotic pressure increase or decrease? Why? b). Also, predict what will happen to the tissues. Will the tissue fluid levels stay the same, increase in the amount of fluid (swell) or decrease in the amount of fluid? 3. In a patient with pneumonia (a respiratory condition that results in lower levels of oxygen in the blood), will diffusion of oxygen between the blood and cells increase, decrease, or stay the same in comparison to normal? Explain. 4. A patient is admitted to the hospital and given intravenous (IV) fluids. Four hours later, the patient complains that his mouth and eyes feel dry. You notice that he displays signs of dehydration, and when you check his IV, you see that he was given the wrong kind of fluids. Were these fluids likely hypotonic, isotonic, or hypertonic? Explain.
