About Respiratory Adaptations in Hypoxia, Anemia and with Pressure Changes MCQs

The four hypoxia types and their arterio-venous oxygen differences, citrate-phosphate-dextrose preservation of 2,3-BPG and carbon dioxide's twenty-fold diffusion advantage headline these Respiratory Adaptations in Hypoxia, Anemia and with Pressure Changes MCQs, which test hypoxia as high-yield NEET PG revision.

Sample Respiratory Adaptations in Hypoxia, Anemia and with Pressure Changes MCQs with answers

Sample MCQ #1

Blood stored in citrate phosphate dextrose is better for hypoxia patients, than acid citrate dextrose because:

AIt has less P50
BIt is less acidic
CThe fall in 2,3 BPG is less
DNone of the above
Show Answer & Explanation ▾
✓ Correct Answer: C. The fall in 2,3 BPG is less

2-3 bisphosphoglycerate binds to beta chain of the hemoglobin, this is required in Rbcs to release oxygen from hemoglobin at the tissue leaving Right Shift therefore CPD is preferred over ACD In hypoxic patient so that 2-3BPG fall less and Oxygen delivery to tissues is better.

Sample MCQ #2

Formula to calculate minute ventilation volume:

ATV X RR
BFiO 2 /PEEP
CTV X (RR - dead space)
DTV + (RR - dead space)
Show Answer & Explanation ▾
✓ Correct Answer: A. TV X RR

Minute ventilation Also called as pulmonary ventilation It is the volume of air inspired or expired per minute It is equal to the tidal volume (TV) multiplied by respiratory rate (RR) Minute ventilation = TV X RR Normal minute ventilation is 6-7.5L/min Reference: Ganong 25th edition page no.628

Sample MCQ #3

CO 2 diffuses more easily through the respiratory membrane than O 2 because it is

ALess dense
BMore soluble in plasma
CLess molecular weight
DLes PCO 2 in the alveoli
Show Answer & Explanation ▾
✓ Correct Answer: B. More soluble in plasma

The diffusion coefficient of CO 2 is about 20 times that of O 2 So, CO 2 diffuses much faster and easily than O 2 Reference: Ganong, 25th edition page no.639

Sample MCQ #4

Oxygen therapy is least useful in -

AAnemia
BARDS
CAlveolar damage
DCOPD
Show Answer & Explanation ▾
✓ Correct Answer: A. Anemia

For anemia, hemoglobin levels have to be increased by blood transfusion Reference: Ganong, 25th edition page no.647

Sample MCQ #5

Arterial O2 content is reduced in one of the following

AStagnant hypoxia
BAnemic hypoxia
CHistotoxic hypoxia
DIschemia hypoxia
Show Answer & Explanation ▾
✓ Correct Answer: B. Anemic hypoxia

Characterized by reduction in hemoglobin concentration and decline in the O 2 -carrying capacity of the blood (reduced arterial O 2 content) Anemic hypoxia is seen in Carbon monoxide poisoning and methemoglobinemia Reference: Ganong, 25th edition page no.646

Sample MCQ #6

Arterial O2 content is decreased in hypoxia due to

ACyanide poisoning
BCO poisoning
CCOPD
DShock
Show Answer & Explanation ▾
✓ Correct Answer: B. CO poisoning

CO poisoning causes anemic hypoxia where arterial oxygen content decreases Reference: Ganong, 25th edition page no.646

Sample MCQ #7

Among which hypoxia AV O2 difference is max-

AHistotoxic
BStagnant
CHypoxic
DAnemic
Show Answer & Explanation ▾
✓ Correct Answer: B. Stagnant

Arterio venous O 2 difference (a-v-O 2 difference) is increased in stagnant hypoxia Arterio venous O 2 difference (a-v-O 2 difference) is decreased in histotoxic hypoxia Reference: Ganong, 25th edition page no.647

Sample MCQ #8

Cyanosis in trauma is interpreted as-

AEarly sign of hypoxia
BLate sign hypoxia
CAbsence of cyanosis is means adequate tissue ventilation
DAbsence of cyanosis is means adequate tissue oxygenation
Show Answer & Explanation ▾
✓ Correct Answer: B. Late sign hypoxia

Cyanosis in trauma is an extremely Late sign Hypoxemia or it doesn't occur at all Reference: Ganong, 25th edition page no.646
