  2. Cerebral death
  3. Imminent death
  4. Natural death

Answer to Question 1

2
Rationale:
1. Heartlung death, the irreversible cessation of cardiorespiratory functions, has not occurred, because the child is being mechanically ventilated.
2. Cerebral death, or brain death, is the irreversible cessation of all brain functions, including those of the cerebral cortex and brainstem, manifested by the absence of brain waves on EEG.
3. Imminent death means physical death is inevitable within a period of time.
4. Natural death is allowing cessation of all body functions without extraordinary medical interventions.

Answer to Question 2

D

Feedback
A Estrogen plays a vital role in pregnancy, but it is not the primary hormone for maintaining pregnancy.
B hCG levels rise at implantation but decline after 60 to 70 days.
C Oxytocin stimulates uterine contractions.
D Progesterone is essential for maintaining pregnancy; it does so by relaxing smooth muscles. This reduces uterine activity and prevents miscarriage.
