Calculate the velocity of nerve impulse in the Frog's nerve muscle preparation from the data
given below:

५)
(0)

(फ)

Latent period with stimulation of spinal end of the nerve = 0.01 sec.
Latent period with stimulation of muscle end of the nerve = 0.005 sec.
Length of the nerve between the two stimulated points = 7.5 cm.

೨0 the velocity of the nerve impulse is

(ക്ര 1660 दप (18 1576 cm

(C) 1600 cm (D) 15000 cm

Calculate the respiratory quotient from the datas are given :

@
ம்‌
(फ)

Volume of expired air in 8 minutes = 30 liters
Percentage of CO, in expired air = 4.2%

Oxygen consumption in 6 minutes = 1470 ml,

the respiratory quotient (RQ) is

(ക 0.85 (ए) 0.75
(0 5 (D) 0.81

Determine the oxygen carrying capacity and oxygen content of arterial and venous blood
samples from the data are provided :

(0)
(0)
(1)

Percentage saturation of arterial blood with oxygen = 97%

Percentage saturation of venous blood with oxygen = 16%

Hemoglobin concentration = 14.5 g/dl.

Oxygen carrying capacity of blood and oxygen content of venous blood are respectively.
(ಹ) 18.33 ml/dl, 14.37 ml/100 ml ല്‍ 19.48 17041, 14.57 711100 को

Find out the breathing reserve and the dyspnea index from the data provided below :

@
ॐ)
प)

Respiratory rate = 12/min

Tidal volume = 500 ml

Maximum Voluntary Ventilation (MVV) = 130 liters
So Dyspnea index (Breathing reserve percent) is

ക്ര 88% (18 98%
(¢) 80% (2) 100%

Calculate the heart rate from the ECG provided 1500 by the number of smallest squares
between two R waves are assume 18, the heart rate will be:

(A) 82/min (B) 78/ min
(C) 68/min ^ (0) 72/1
