Question
Uncontrolled diabetes mellitus will results in a) respiratory acidosis b) respiratory alkalosis c) metabolic acidosis d) metabolic alkalosis Which of the following is most likely in a patient suffering emphysema (assume the uncompensated condition). a) alkalosis with low plasma PCO_2 b) alkalosis with high plasma PCO_2 c) acidosis with low plasma PCO_2 d) acidosis with high plasma PCO_2 Excessive release of atrial natriuretic hormone (also called atrial natriuretic peptide) will most likely result in a) low plasma sodium and hypotension b) low plasma sodium and hypertension c) high plasma potassium and hypotension d) low plasma anions and hypotension Why is osmotic pressure considered a colligative property of solutions? a) its value is depending on facultative reabsorption in renal tubules b) its value depends on the number of particles in a solution not the type c) its value is determined by the amount of water in a container d) its value obeys fluid movemExplanation / Answer
19. The correct answer is metabolic acidocis (c). During uncontrolled diabetes mellitus, excessive ketone bodies are formed which are acidic in nature and causes metabolic acidosis.
20. The correct answer is acidocis with high plasma PCO2. Emphysema is characterized by abnormal breathing which impairs the lung to remove CO2 from blood which causes high PCO2 (pressure of CO2) in blood which ultimately causes respiratory acidosis.
21. The correct option is a. ANP (atrial natriuretic peptide) is released from atrial muscle cells of the heart in response to high blood pressure. ANP inhibits the reabsorption of sodium and hence sodium level and water level decreases in blood which causes reduction in blood volume and ultimately causes hypotension (low blood pressure due to low blood volume).
22. Option b is correct. Colligative properties of solution depends upon concentration of solutes not the type of solutes. It includes vapour pressure, boiling point, freezing point and osmotic pressure.
23. Option d is correct. Osmorecetors are found in hypothalamus which regulate water intake (thirst) and water conservation (renal) by controlling the release of antidiuretic hormone (ADH).
