Part c,d and e PLEASE
There are two patients who enter the hospital, each with weak distal pulses, elevated heart rate, and severe hypotension (i.e., low blood pressure). One patient is suffering from dehydration due to the water-borne disease cholera, whereas the second patient has been involved in a severe car accident Both have stabilized fluid/blood loss, yet standard emergency protocols differ for these two patients Answer the questions below about each patient to gain insight into why rehydration and attempts to restore blood pressure differ for these two patients. (14 points) Both patients suffer from hypotension. Describe a control system engaged to restore blood pressure. Be sure to identify the typical components of a reflex and state whether blood pressure is homeostatically controlled by negative or positive feedback. (5 points) a. b. Before medical intervention, predict each patient's blood osmolarity (i.e., isosmotic, hypoosmotic, or hyperosmotic) (2 points) i. Cholera Patient with Dehydration ii. Car Accident Victim with Blood Loss Suppose the car accident victim lost 0.5 L of blood. Paramedics infuse 500 cc of 140 mM saline. Assuming that reference blood osmolarity is 300 mOsM, what happens to the patient's plasma osmolarity after infusion? (increase/decrease/no change)? (2 points) Assume the volume of the car accident victim's plasma (before the IV) was 2.5 L. Assume that there was complete mixing of the infusion with plasma, but no mixing with interstitial fluid. Calculate the patient's plasma osmolarity after the infusion mixed with her plasma but before any water enters her red blood cells. (3 points). c. d. e. Rehydration protocols differ in resource-limited areas (i.e., Haiti) and developed countries (i.e., US). Emmanuel required intravenous isotonic fluids in addition to ORS for rehydration Rehydration protocol in the US is infusion of hypotonic fluids intravenously slowly over 24- hours. Why might rehydration protocols differ between resource-limited areas and developed countries? Predict what might happen to the patient's RBC volume with improper rehydration. (2 points)Explanation / Answer
C.the patient plasma osmolarity will decrease, since 140 mOsM saline is added to 300 mOsM blood. You can assume that the blood is 300 mOsM, since the RBCs are 300 mOsM and the body should be in osmotic equilibrium.thus the plasma osmolarity decreases.
D.how to calculate the osmolarity is given below-osmolarity is 293 mOsM.
Blood: 2.5 L * 300 mosmoles/L = 750 mosmoles (IV): 130 mmoles/L = 260 mosmoles/ L; 0.5 L * 260 mosmoles/L = 130 mosmoles The osmolarity is then (750 + 130 )mosmoles / 3 L = 293 mOsM
E. Dehydration—as the volume of the body fluid in the blood drops, the count of red bloos cells per volume of fluid rises.The body tries to compensate by producing more red blood cells.which make your blood thick and which result into blood clots which causes heart attack.it is very important to maintain the water balance in the blood.
