Chapter No. 1 Homeostasis
Q.31 In case of uremia,to remove nitrogenous wastes, particularly the urea, the blood of the patient is treated through:
A) Centrifugation
B) Lithotripsy
C) Transfusion
D) Dialysis
Answer:
D) Dialysis
Answer:
Answer is “Dialysis”.
Explanation:
Dialysis is a temporary measure to clean the blood off nitrogenous wastes until the kidney transplant is managed.
Q.32 There are two types of dialysis i.e.:
A) Blood dialysis and peritoneal dialysis
B) Plasma dialysis and peritoneal dialysis
C) Hemodialysis and peritoneal dialysis
D) Hemodialysis and permanent dialysis
Answer:
C) Hemodialysis and peritoneal dialysis
Answer:
Answer is “Hemodialysis and peritoneal dialysis”.
Explanation:
Hemodialysis is a pure mechanical dialysis whereas in peritoneal dialysis a human membrane called peritoneum is used as filtering membrane to isolate the nitrogenous wastes from blood.
Q.33 Hemodialysis means:
A) Cleaning the blood
B) Replacing the blood
C) Washing the blood
D) Centrifugation of the blood
Answer:
A) Cleaning the blood
Answer:
Answer is “Cleaning the blood”.
Explanation:
Hemodialysis literally means cleaning the blood.
Q.34 The wastes and excess water pass during dialysis from blood through the membrane:
A) Into the body
B) Out of the body
C) Into the dialysis fluid
D) Out of the dialysis fluid
Answer:
C) Into the dialysis fluid
Answer:
Answer is “Into the dialysis fluid”.
Explanation:
Wastes are collected in dialysis fluid during dialysis.
Q.35 Peritoneal cavity is filled with dialysis fluid that enters the body through a/an:
A) Artery
B) Vein
C) Capillary
D) Catheter
Answer:
D) Catheter
Answer:
Answer is “Catheter”.
Explanation:
A catheter is a thin tube made from medical grade materials, serving a broad range of functions along with filling and draining the dialysis fluid from peritoneal cavity.
Q.36 It is the kidney machine that works on the same principle as the kidney for removal of wastes and excess water from the blood:
A) Catheter
B) Peritoneum
C) Dialyzer
D) Epithelium
Answer:
C) Dialyzer
Answer:
Answer is “Dialyzer”.
Explanation:
As the name indicates, it is a dialysis machine.
Q.37 The surgical transplantation of a matching donor’s kidney is the only option left for the permanent treatment of:
A) Kidney stones
B) Hypercalcemia
C) Uremia
D) Hyperoxaluria
Answer:
C) Uremia
Answer:
Answer is “Uremia”.
Explanation:
Uremia is an end stage kidney failure and it can be treated with kidney transplant only.
Q.38 Homeostasis is the central requirement in the maintenance of an organism, which compels the ________ in constant changing conditions and contribute in evolutionary process.
A) Thermoregulation
B) Osmoregulation
C) Excretion
D) Adaptations
Answer:
D) Adaptations
Answer:
Answer is “Adaptations”.
Explanation:
Adaptations gradually accumulate and become a result of evolution in longtime.
Q.39 Pick up the matching one:
A) Conservation of water-concentration of filtrate
B) Conservation of water-diluted urine
C) Restricted supply of water-diluted urine
D) Sufficient supply of water-concentration of filtrate
Answer:
A) Conservation of water-concentration of filtrate
Answer:
Answer is “Conservation of water – concentration of filtrate”.
Explanation:
When water is taken back from the filtrate it becomes concentrated.
Q.40 Pick up the incorrect one:
A) Conservation of water results in concentration of filtrate
B) Restricted supply of water cause conservation of water
C) Release of ADH is inhibited in the presence of hypo-osmotic body fluids
D) Reduction in reabsorption results in production of small volume of conc. urine
Answer:
D) Reduction in reabsorption results in production of small volume of conc. urine
Answer:
Answer is “Reduction in reabsorption results in production of small volume of conc. urine”
Explanation:
When reabsorption from filtrate is reduced it results in production of massive volume of diluted urine.
