  3. 12.5 remains in the body.
  4. 8 remains in the body.

Answer to Question 1

3
Rationale: The 8-hour half-life means that 50 is left in the body after 8 hours.

Answer to Question 2

1
Rationale: Very often, the only sign of pain that the nurse will see is the immobilization of the affected area of pain by the client. This can be particularly true of small children if the pain is not severe. The mother cannot tell the nurse the level of the child's pain. Toddlers might or might not play quietly, depending on the toy. Toddlers usually ignore other children and engage in parallel play.
