During adult CPR, your partner notes that

Multiple choice — select the best answer

AThe compression rate will automatically increase above 120/min
BThe compression depth will exceed the maximum safe limit
CVenous return to the heart will be reduced, lowering cardiac output
DVentilation volumes will increase due to higher intrathoracic pressure

✓ Correct answer: C. Venous return to the heart will be reduced, lowering cardiac output Incomplete chest recoil (leaning on the chest) elevates intrathoracic pressure and impairs venous return, which decreases cardiac output and reduces the effectiveness of CPR.
