1.Human anatomyMedium

Which pulse is felt just behind the medial malleolus of the ankle?

  1. ADorsalis pedis artery
  2. BPopliteal artery
  3. CPosterior tibial artery
  4. DFibular artery
2.Human anatomyHard

After a fracture of the midshaft of the humerus, a patient cannot extend the wrist and fingers ("wrist drop"). Which nerve is most likely injured?

  1. ARadial nerve
  2. BMedian nerve
  3. CAxillary nerve
  4. DUlnar nerve
3.Human physiologyMedium

Vital capacity is the sum of which lung volumes?

  1. ATidal volume and residual volume
  2. BTidal volume, inspiratory reserve volume and expiratory reserve volume
  3. CResidual volume and expiratory reserve volume
  4. DInspiratory reserve volume and residual volume
4.Human physiologyHard

Why does a deep sea diver risk decompression sickness when surfacing quickly?

  1. AThe lungs collapse when the pressure falls
  2. BOxygen becomes toxic at the surface
  3. CNitrogen dissolved at high pressure forms bubbles as the pressure falls
  4. DCarbon dioxide cannot leave the lungs fast enough

2Solutions

1.Human anatomy

Answer: C · Posterior tibial artery

Why this is the answer

The posterior tibial artery passes behind the medial malleolus into the sole. The dorsalis pedis pulse is felt on the top of the foot.

Answer

C · Posterior tibial artery
2.Human anatomy

Answer: A · Radial nerve

Why this is the answer

The radial nerve runs in the radial (spiral) groove of the humeral shaft. It supplies the wrist and finger extensors, so injury causes wrist drop.

Answer

A · Radial nerve
3.Human physiology

Answer: B · Tidal volume, inspiratory reserve volume and expiratory reserve volume

Why this is the answer

Vital capacity = IRV + TV + ERV. It excludes the residual volume, which always stays in the lungs.

Answer

B · Tidal volume, inspiratory reserve volume and expiratory reserve volume
4.Human physiology

Answer: C · Nitrogen dissolved at high pressure forms bubbles as the pressure falls

Why this is the answer

At depth more nitrogen dissolves in the tissues. If pressure falls too fast it comes out of solution as bubbles in tissues and blood, causing "the bends".

Answer

C · Nitrogen dissolved at high pressure forms bubbles as the pressure falls
