A 65 years old patient had a major abdominal surgery a day ago. It is known that during surgery he had a few episodes with a significant decrease in blood pressure. It did require an additional administration of fluids intravenously. Currently this patient has a serum sodium level of 122 mEq/L and a serum osmolality is 250 mOsm/kg. He shows no evidence of dehydration. Describe the sequence of physiogical events that led to this abnormality and its possible consequences.

The renal handling of a novel drug is being studied. When the drug is present in the blood, it is filtered into the Bowman’s capsule and secreted via transport proteins in the renal tubules, but it is NOT reabsorbed. The lines on the following graph represent filtration, secretion and excretion rates of this drug at various plasma concentrations. For the three lines shown (labeled A-C) identify which line represents filtration, which line represents secretion, and which line represents excretion Explain how you determined this.

30, With respect to renal autoregulation, myogenic mechanism refers to Multiple Choice both glomerulus increase of blood flow and macula densa secreting renin are correct ability of macula densa to sense a increase in Na+ content in tubular fluid and secrete renin in response ability of a muscle to contract reflexively without nervous stimulation to adjust blood vessel diameter ability of glomerulus to increase blood flow and increase filtration rate
Renin is secreted in response to hypovolemia or to an increase in the osmolality of the blood. Provide three possible mechanisms by which these conditions may stimulate rennin secretion. What are the consequences of increased rennin secretion that lead to increased aldosterone secretion? Present this sequence of events. Why are angiotensin converting enzyme inhibitors (ACEIs) used as a common therapy for hypertension? How do they influence blood pressure? Are plasma levels of renin elevated or depressed in a patient with Conn’s disease? Why?
In a person with diabetes mellitus, what would be causing polyuria? Glucose has saturated the secondary active transporters in the PCT that move glucose into the cells, increasing the concentration gradient between the filtrate and the ISF or Glucose has saturated the secondary active transporters in the PCT that move glucose into the cells, reducing the concentration gradient between the filtrate and the ISF
An investigator is studying renal physiology in patients with type 1 diabetes mellitus. When a substance that inhibits glucose reabsorption is given, which of the following best describes the clearance of glucose?a. Decreases and approaches the clearance of p-aminohippurateb. Decreases and approaches the clearance of inulinC. Increases and approaches the clearance of p-aminohippurated. Increases and approaches the clearance of inuline. Increases and approaches the clearance of sodium
In the management of DKA, why would potassium be added to the maintenance fluids even if potassium levels are normal or high? Question 66 options: a) Potassium shifts from the extracellular fluid to the intracellular fluid when acidosis corrects b) Insulin promotes renal potassium loss c) Osmotic diuresis may continue to deplete extracellular fluid potassium levels d) Maintenance fluids will dilute potassium levels in the extracellular fluid
Which of the following is TRUE about glucose reabsorption in the kidney? a.If an individual does not have diabetes mellitus, 100% of filtered glucose is reabsorbed at the proximal convoluted tubule. b.If an individual has diabetes mellitus, filtered glucose will be present in all the renal tubule. c.Glucose reabsorption along the proximal convoluted tubule uses the sodium glucose secondary active transporter and it is independent of insulin. d.All of the above e.None of the above asap
The immediate effect of ADH on the renal tubules of frogs and mice is the same, yet when ADH is secreted, frogs produce urine that is approximately isosmotic to their blood plasma, whereas mice produce urine far more concentrated than their blood plasma. Explain this difference in terms of the factors affecting osmosis in the kidneys of frogs and mice.
the major difference between plasma and interstitial fluid is the absence of plasma proteins from the interstitial. explain how this affects solute distrbution and what kind of correction you would do it if you were measuring solute concentration
Which of the following is TRUE concerning glucose transport across the proximal convoluted tubule (PCT)? Group of answer choices must choose one answer Glucose is usually absorbed approximately 70% here and the remainder of the absorption is under hormonal control in the distal convoluted tubule (DCT). Glucose moves by paracellular transport. Glucose moves across the apical membrane by secondary active transport via co-transport with sodium. Glucose transport is passive, requiring facilitated diffusion across both the apical and basolateral membranes.
What are major factors that determine blood osmolality? The osmolality of 0.9% NaCl is ___________. How is the osmolality different from the molarity? Also, predict the effect of 1 L of 600 mOsm/L infusion of sucrose on patients RBC’s osmolality and volume, if previous osmolality of RBC’s was 250 mOsm/L, plasma volume – 3.6 L and RBC’s volume – 2.4 L.
