  The characteristics of sperm that have undergone capacitation include the: Note: Credit will be given only if all correct and no incorrect choices are selected. Select all that apply. 1. Ability to undergo an acrosomal reaction.
  2. Ability to block polyspermy.
  3. Ability to bind to the zona pellucida.
  4. Ability to release the protease acrosin.
  5. Acquisition of hypermotility.

Question 2

Persistent early decelerations are noted. What would the nurse's first action be?
 
  1. Turn the mother on her left side and give oxygen.
  2. Check for prolapsed cord.
  3. Do nothing. This is a benign pattern.
  4. Prepare for immediate forceps or cesarean delivery.

Answer to Question 1

1,3,5
Rationale 1: Sperm that undergo capacitation take on the ability to undergo the acrosomal reaction.
Rationale 2: At the moment of penetration by a fertilizing sperm, the zona pellucida undergoes a reaction that prevents additional sperm from entering a single ovum. This is known as the block to polyspermy.
Rationale 3: Sperm that undergo capacitation take on the ability to bind to the zona pellucida.
Rationale 4: null
Rationale 5: Sperm that undergo capcitation have the acquisition of hypermotility.

Answer to Question 2

3
Explanation: 3. Early decelerations are considered benign, and do not require any intervention.
